(5) GAS CLEANING DEVICE

 ,,. ,; one . , . : /;

The invention relates to devices for separating dispersed particles from gases, air or vapors of CHP plants, boiler houses, sintering and firing machines, melting furnaces, converters, pickling and electrical insulation plants, powerful aspiration systems in the metallurgical, chemical, energy and other industries using fluids as a release agent.

A gas cleaning apparatus is known, comprising a housing with a drip tray and nozzles for supplying and. removal of gas and liquid, inside which vertical partitions are installed, forming gas cleaning channels 1.

A disadvantage of this device is the low degree of purification of gas flowing through vertical channels, whose operation is based on the inertial effect when changing the direction of the gas flow.

The closest to the proposed invention to the technical essence and the achieved result is a device for gas purification, including a housing with a drip tray and nozzles for supplying and discharging gas and liquid, a bubbling device. D2.

The disadvantages of this dust collector are the low degree of gas flow turbulence, the contact surface of dust and liquid particles is small, the impossibility of trapping dust particles of less than 5 microns for the indicated reasons, the inability to control the cleaning mode

tS gas, the need to use hot water and nozzles that quickly become clogged or wear out and go out of service.

The aim of the invention is to increase the degree of gas purification.

Claims (2)

The goal is achieved by the fact that a gas-cleaning device with a cap with a condenser and nozzles for supplying and discharging gas and liquid is equipped with a bubbling device, which is equipped with transverse water supply pipes and horizontal parallel plates fitted with flow turbulators , with the plates in pairs on one side connected to the pipes, forming a gas cleaning channels. The pipes are equipped with rotary valves, the turbulators are made in the form of segments and installed, according to the internal plates, plates. In addition, the device is equipped with a reflector made in the form of a vertical partition or in the form of a lattice. FIG. 1. shows the proposed gas cleaning device, a longitudinal section V in FIG. 2 is the same cross section} in FIG. 3 gas cleaning channels, a longitudinal section in FIG. k — yctan of the pivot pipe of the flap, unit 1 in FIG. 2. The device includes a housing 1 with nozzles for supplying 2 and discharging gas 3 of the plate 4, with turbulators 5 and through pepper pipes 6 for supplying the gas cleaning liquid. Each pipe is provided with a rotary tubular valve 7, which can be rotated around its axis by means of a shaft 8, change the area of the gas inlet opening into the pipe and thus adjust the amount of incoming gas to be purified. The device includes a reflector 9 made in the form of a partition or a package of parallel inclined plates in the form of a louvered grille located perpendicular to the gas cleaning channels at a distance of 0.5-1 m: from the gas cleaning channels. In the device, the liquid is supplied to the gas cleaning channels by means of a junction box 10, inside of which there are wedge-shaped overflow pipes 11, these tubes are connected to the pipes 6 by means of hoses 12. The circulation pump 13 through pipelines 1 and 15 ensures continuous recirculation gas cleaning fluid inside the apparatus. The device is provided with a side chamber 16 for removing sludge, a drip catcher 17 and a hopper 18 for removing dry dust. As turbulizers, besides tubular segments, channel bars, angles, etc. can also be used. The gas cleaning device operates as follows. Dangerous gas from the furnace with the temperature before and the dust content up to 100 g / mm and more is fed to the apparatus through the nozzle 2. Dust particles larger than 5 microns are deposited under the action of inertial forces into the bunker 18 and removed from it then dry. Partially purified gas at a speed of m / s enters the transverse pipes 6, captures the top layer of gas cleaning liquid, breaks it up into tiny droplets and foam, and then this gas-liquid flow at a speed of 30-60 m / s dL1gaC in gas-cleaning channels formed by plates and a turbulator and 5. In this case, there is an intensive mixing of gas and liquid and the trapping of dust particles and other impurities by the smallest drops of gas cleaning liquid and foam for a diffusion estimate. adhesive, inertial and absorption effects. Then gas-bone flows at a speed of 30-60 m / s hit d6 reflector 9. As a result, impact splitting of liquid droplets and the formation of foam and mist occur, additionally intensifying the trapping of impurities from the gas. The cleaned gas with a dust content of 0.001-0.005 g / m and a temperature of 20-80 ° C enters at a speed of 2-4 m / s and the droplet separator 17, is released from liquid droplets and then is removed from the apparatus through pipe 3. The hydraulic resistance of the gas cleaning device is 100150 kgf / m (1-1.5 kPa) and can, if necessary, be increased to 1000-1500 kgf / m - (10-15 kPa) with particularly fine gas cleaning by disconnecting a certain number of gas-cleaning channels using rotary tubular valves 7. The specific consumption of meat / bone for gas cleaning is 0.001-0.5 l / m of gas, the capacity of the device is up to 20 million MV4. This device is simple, compact, reliable, highly efficient and allows you to purify gases from virtually any impurities to any residual concentration and, accordingly, using it increases the degree of gas purification from harmful impurities.
