Background technique

With the development of the national economy, the problem of air pollution is becoming more and more serious. How to ensure air quality has become the bottleneck of sustainable economic development, and air purification technology is now becoming more and more important.

Increasing urban green area is an effective way to improve air quality, but it is not so easy to implement. Most cities in my country are in the stage of infrastructure construction, and it will take some time to shift the focus to greening construction, and the urgent need for air pollution cannot be resolved in the short term.

In recent years, the development of air purifiers is relatively rapid, and various air purifiers emerge in endlessly. However, most of the air purification products are only for indoor use, the price is high, and they cannot be popularized on a large scale, and they have little effect on improving the air quality in cities.

According to the search, the existing air purifiers, such as the Chinese patent No. 201420804158.X titled "A Power Supply and Control Circuit for Electrostatic Precipitator", place a plurality of rectangular electrode plates in parallel, and the volume is relatively small. Large, it is difficult to adopt an easy-to-place package, and its application range has certain limitations.

Another example is the Chinese patent No. 200820230657.7 titled "A Kind of Electrostatic Precipitator". The discharge electrode of this patent is formed by alternating arrangement of discharge electrode tube units and auxiliary electrode tube units. It has high efficiency and good reliability, but its The structure is complex, and the circuit part is not specially protected, so it is easy to be scrapped when a fault occurs.

To sum up, although the problem of air pollution has been paid attention to, there are few air purification products that focus on improving the overall air quality of the city. It is necessary to develop an outdoor air purification system with a simple structure, low cost, strong popularity, and low maintenance costs. device.

Contents of the invention

The purpose of the present invention is to provide an outdoor brick-type air cleaner, which can effectively and effectively solve the problem of air pollution in cities.

The purpose of the present invention is achieved through the following technical solutions: an outdoor brick-type air cleaner, including a circuit part and a mechanical structure part, the electrostatic precipitator circuit includes a main fuse at the input end of the transformer, and a rectifier at the output end of the transformer The input and output of the rectifier are connected to the high-voltage busbar, and the output of the high-voltage busbar is connected to the sub-fuse; the wall net has a number of regular hexagonal holes, and there are sewage channels between adjacent meshes and are connected to each other; the air purification bricks are placed on the regular hexagonal sides In the shaped hole, air passages are provided on the outer walls of the two adjacent sides of the air purification brick, and a plurality of iron wires drawn from the high-voltage bus are arranged below the air passages. A metal sleeve is provided on the periphery of each iron wire, and the sleeve passes through the air passage. The outlet below the air channel extends to the sewage channel of the wall net, and the adjacent sides of the air purification brick are respectively provided with locks or buckles.

The air purifier is distributed in the regular hexagonal holes of the wall net in the form of bricks, and has a regular hexagonal shape.

Each of said air purification bricks contains a sub-fuse, and its sensitivity is lower than that of the main fuse.

The cathode and anode stages of the electrostatic precipitator circuit are in the form of iron wire+conductor bushing.

The wall net is fixed on the outer wall of the building, and the air purification brick is fixed in the mesh of the wall net with a lock. The lower side of the air purification brick has several small holes with a radius of 1 cm, from which a plurality of conductor sleeves are inserted.

Use a step-up transformer to convert 220V AC to 3000V AC, and then use a bridge rectifier for full-wave rectification to output a higher DC voltage, which is drawn out from the high-voltage bus. The iron wires are connected in parallel to the high-voltage busbar, and the air purification bricks are introduced into the air purification bricks through a dedicated channel in the wall net, passing through the inside of each casing and reaching the top. The iron wire and the casing are not in contact with each other.

The present invention realizes air adsorption through the structure of rod+sleeve, and its principle is as follows: the iron rod is used as the anode, and the conductor sleeve is used as the cathode. The strong electric field between the two stages ionizes the air, causing anions to move to the iron rod and cations, carrying dust particles, to the bushing. Compared with the traditional bipolar plate type electrostatic adsorption device, this design has two advantages: it can form electrostatic isolation between multiple iron wires, avoid the mutual interference of the electrostatic fields of multiple iron rods, and then make multiple iron wires work intensively. Possibly, the space utilization rate is improved; the electric field is made uniform, because the insulation level of the air for the uniform electric field is much higher than that of the non-uniform electric field, the breakdown voltage of the device is obtained, and the reliability is increased.

Compared with the prior art, the present invention has the advantages and effects: the outer wall of the building is used as the application occasion, and the air purifier is installed in the form of "brick", which has a wide application space. Different from traditional air purifiers that only focus on indoor air purification, the present invention expands the application field to outdoor air purification. If it is popularized on a large scale, it will have great social benefits.

The maintenance work of the present invention is relatively simple. Dust accumulates on the metal pipe wall and falls directly into the sewage pipe when subjected to external vibrations. The sewage pipes are interconnected tree structures, and the cleaning liquid is poured from the top of the wall network to make it flow through the entire device to complete the cleaning work.

The air purification brick of the present invention is regular hexagonal, beautiful in appearance, and compared with rectangular bricks, it is more conducive to the discharge of fallen dust particles, and compared with round bricks, the space utilization rate is improved.

In the present invention, bricks and wall nets are connected by locks to facilitate the removal of individual bricks.

The power supply module sequentially includes an AC power supply, a fuse, and a transformer rectification circuit.

The transformer rectifier circuit includes a step-up transformer and a full-bridge rectifier.

The high-voltage busbar is connected to a rectifier to supply power to each air purification brick. The power supply circuit of each brick is connected with a fuse whose sensitivity is higher than that of the main circuit fuse.

It also includes a WiFi relay module connected between the fuse and the transformer rectification circuit.

All bushings are grounded through ground straps.

detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

The power supply 1 is a power frequency 220V alternating current, followed by a fuse 2 , a WiFi relay 3 , a step-up transformer 4 , and a bridge rectifier 5 . The outlet 6 of the rectifier is used as a high-voltage bus. Each air purification brick is connected in parallel on the high-voltage bus, and each branch is connected with a fuse 7, whose sensitivity is greater than that of the main fuse 2, so that the fault area is reduced.

The shape of the air purification brick is a regular hexagon, and the outer and inner sides of the shell are hollowed out as the air channel 8 . There are several small holes 9 on the outer side, so that there is air exchange inside and outside the brick. Each iron wire 10 is connected in parallel on the high-voltage bus 6, and is inserted from the lower side of the brick, and the outer layer is covered with a conductor sleeve 11. All iron wires are suspended, and all conductor casings are uniformly grounded.

The potential difference between the iron wire and the casing is as high as 3000V, forming a strong electric field and ionizing the air. The ions attach to the dust particles, "carrying" them to the inner wall of the sleeve 10. The bushing absorbs external vibrations which can cause dust to fall from the tube wall and be discharged through the outlet.

Since the distance between the iron wire 10 and the conductor sleeve 11 is relatively short, short-circuit faults are prone to occur. When a fault occurs, the sensitivity of the fuse 7 is higher than that of the main fuse 2, and the short circuit point can be located to a single air cleaning brick. Adopt snap close 12 to connect between every brick and the wall net. The lock catch is easy to remove, which is convenient for removing bricks and troubleshooting.

Lock catch 12 fixes brick on the wall net. The dust falls to the waste channel 15 through the outlet 9. The entrance 14 of the sewage channel pours into the cleaning liquid, and the cleaning liquid can flow through the whole wall net through the tree-like sewage channel, and flows out from the outlet 13 of the sewage channel, which realizes easy cleaning.
