In the figure: the dust removal device comprises a dust removal barrel body 1, an air inlet cavity channel 2, a cyclone tube cavity 3, an air outlet 4, an atomizing spray pipe 5, an atomizing nozzle 6, a conical liquid collecting tank 7, a liquid seal pipe 8, a liquid seal tank 9 and a manhole 10.
Detailed Description
The present invention will be described more fully and clearly with reference to the accompanying drawings, which are incorporated in and constitute a part of this specification.
As shown in fig. 1 and 2, a wet process cyclone dust removal equipment, including dust removal barrel 1, air inlet chamber way 2 and cyclone tube chamber 3, cyclone tube chamber 3 intercommunication dust removal barrel 1 is passed through to 2 one ends in air inlet chamber way, the fan is connected to the other end that air inlet chamber said 2, the fan is used for letting in dusty air current to equipment and removes dust, be provided with a plurality of atomizing spray pipes 5 in the air inlet chamber way 2, be provided with a plurality of atomizing spray nozzles 6 on the atomizing spray pipe 5, atomizing spray nozzle 6 is used for spraying the rivers in the atomizing spray pipe 5 and forms the curtain that one water sprays, dust removal barrel 1 top is provided with air outlet 4, purifies back air current and passes through air outlet 4 and discharges, dust removal barrel 1 below is provided with album of liquid device, album of liquid device is used for retrieving dusty liquid drop. The vertical setting of atomizing spray tube 5 is in air inlet chamber way 2, atomizing nozzle 6 on the atomizing spray tube 5 evenly sets up, makes the water that it sprays out drench curtain evenly distributed. The liquid collecting device comprises a conical liquid collecting tank 7, a liquid seal pipe 8 and a liquid seal tank 9, the bottom surface of the conical liquid collecting tank 7 is communicated with the lower part of the dust removing cylinder body 1, the top end of the conical liquid collecting tank 7 is connected with the liquid seal pipe 8, the liquid seal pipe 8 is led into the liquid seal tank 9 filled with solution, and the liquid seal tank 9 is arranged to prevent dust-containing liquid drops at the bottom of the dust removing cylinder body 1 from being sucked to the upper part again by high-speed rotating airflow. The upper end of the air inlet cavity channel 2 is provided with a manhole 10. For checking the operating condition of the atomising nozzle 5.
The working process is as follows:
the wet cyclone dust removal equipment is connected with an outlet pipeline of the fan when in use, and when the fan runs, the spraying water valve is opened simultaneously; the air flow from the outlet of the fan enters the air inlet cavity channel 2 along the straight line direction; after water with certain pressure is atomized by a specially selected atomizing nozzle 6, a curtain wall with water spraying is formed at an inlet; when the airflow passes through the cyclone tube cavity 3, dust particles and liquid drops collide to be intercepted and condensed, water mist is combined to form particles larger than 10 mu, the particles collide to be intercepted and condensed to form large liquid drops, the large liquid drops flow downwards along the tube wall in a spiral shape to the conical liquid collecting tank 7 to be discharged, the outer cyclone airflow which rotates and descends continuously flows into the central part of the dust removal tube body 1 in the descending process to form centripetal radial airflow, and the airflow forms inward cyclone which rotates upwards; the rotation directions of the inner rotational flow and the outer rotational flow are the same, the bottom of the dust removal cylinder 1 is provided with a water seal, and the purified air flow can only be discharged through the air outlet 4; because the water spray direction and the air flow direction are opposite, the air flow and the fog drops collide more intensely and contact more fully; therefore, the dust removal effect is better; when the device is used for secondary dust removal, the emission can reach less than 25mg/m < 3 > (ppm) which is far lower than the national standard, but the water consumption is only 20Kg/t powder to 25Kg/t powder which is far less than the water consumption of a tower spray washer (800 Kg/t powder), the collected water can be recycled, and the heat of the tail gas is fully utilized.
According to the structure of the utility model, the wet cyclone dust removal equipment of the utility model has small volume and greatly reduces water consumption; the dust removal efficiency is high, and fine dust particles with the particle size of less than 10 mu m can be removed; simple structure, convenient use and low maintenance cost.
