Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
The electric dust collector adopted in the market at present is arranged in a module form, and can be combined with other arrangement forms on the basis of the independent arrangement form of vertical circular airflow and horizontal flue gas flow; adopt dry-type dust remover to need to adopt rapping device, produce the condition of secondary raise dust easily, and the wet-type electrostatic precipitator who exists on the market, the required a large amount of water of equipment can cause the wasting of resources, and sewage burden is too big moreover, handles improperly to circulation operation, will influence the environment, causes secondary pollution to the environment, and dust collecting equipment also can be easily corroded the damage by sewage. Therefore wet electrostatic precipitator technique needs constantly research and development and improves, to this the utility model provides a wet-type is gathered dust and dust collector.
The utility model also provides the following preferred embodiment
As shown in fig. 1 and 2, the wet dust collecting and removing device comprises a main platform 1, wherein a dust removing tower 2 and an exhaust chimney 3 are erected on the main platform 1, and the dust removing tower 2 is formed by assembling a circular cylinder and a conical top cover; a plurality of spray pipe groups 5 are arranged in the dust removing tower 2 and are distributed at equal intervals in the vertical direction; the spraying pipe group 5 is connected with a water inlet pipe 4 arranged outside the dust removal tower 2, and the inlet end of the water inlet pipe 4 is connected with external cooling water and is pressurized and conveyed through a water pump; an air outlet is reserved at the top of the dust removing tower 2, and an air guide device 6 is arranged between the air outlet of the dust removing tower 2 and an air inlet of the exhaust chimney 3. After the smoke and dust that produces in the production process enters into gas wash tower 2, inlet tube 4 is with the leading-in shower nest of tubes 5 of cooling water after, and the spray water smoke carries out the dust fall to the smoke and dust in whole gas wash tower 2 and handles. And a mode of overlapping multiple layers of the multilayer spraying pipe group 5 is adopted to perform dust fall on the smoke dust for multiple times.
Flue gas contact water smoke in-process, the particulate matter in the flue gas can condense with water smoke, forms the liquid film simultaneously in whole gas wash tower 2, under the self gravity of water and the flow of flowing flue gas, the liquid film can be torn, produces a large amount of liquid drops. The thermophoretic force is generated by the temperature gradient between the flue gas and the tube row, and the particles are promoted to move towards the tube wall. The movement of the particles tends to be disordered by combining the Brownian diffusion of the fine particles and the disturbance of the tube rows to the smoke, thermophoresis and diffusion electrophoresis, so that the collision frequency among the particles is improved, and the particle agglomeration is strengthened. Due to the existence of inertial collision, liquid drop interception and Brownian diffusion, partial particles and large liquid drops in the smoke are trapped. Dust large particles fall into the bottom of the dust removal tower 2 along with large liquid drops to be collected, so that dust removal treatment is efficiently realized on the smoke dust.
