Abstract
A tower type exhaust treatment device and an exhaust treatment method are disclosed. With continuous advancement of the society and continuous development of industrialization, many environmental problems are generated, and exhaust removal treatment is considered as the top priority. A tower-type exhaust treatment device comprises an exhaust pollution source collection tank (1), which is connected to an exhaust hood (2). The exhaust hood is connected to a centrifugal fan (4) through an exhaust duct (3). The centrifugal fan is connected to an adsorption tower through an exhaust pipeline. An absorption liquid tank (7) is arranged below the adsorption tower. The bottom of the adsorption tower has a grid (8). A packing layer (9) is arranged on the grid. An airflow equalization layer (10) is arranged on the packing layer. A packing layer (11) is arranged on the airflow equalization layer. A water sprinkler (14) is arranged on the packing layer. A grid (12) is arranged on the water sprinkler. A demisting layer (13) is arranged on the grid. The right end of the adsorption liquid tank is connected to an adsorption liquid circulating pump (16) through a tube bundle. The invention is used for exhaust treatment of the tower-type exhaust treatment device.
Description
Technical field:
The present invention relates to a kind of tower emission-control equipment and waste gas processing method.
Background technology:
Along with the continuous progress of society, industrialization development, create many environmental problems therewith, wherein the process removing waste gas is classified as the most important thing.Waste gas not merely can contaminated air, affect the living environment of people, more importantly can endanger the health of the mankind, band serves unnecessary disease and pathogenic bacteria, along with the generation of greenhouse effect and increasing the weight of of air harm, it is accomplished by after enterprise and factory process for unnecessary tail gas exhaust in discharge, brings good fresh air.
Summary of the invention:
It is an object of the invention to provide a kind of tower emission-control equipment and waste gas processing method.
Above-mentioned purpose is realized by following technical scheme:
A kind of tower emission-control equipment, its composition includes: exhaust emission source collecting pit, described exhaust emission source collecting pit is connected with hood, described hood is connected with centrifugal fan by discharge duct, described centrifugal fan is connected with absorption tower by gas exhaust piping, there is under described absorption tower absorption liquid bath, bottom described absorption tower, there is grid, described grid has packing layer, described packing layer has air-flow equalizing layer, described air-flow equalizing layer has packing layer, described packing layer has Water spray device, described Water spray device has grid, described grid has except mist layer, described removing has exhanst gas outlet on mist layer, described absorption liquid bath right-hand member is connected with absorption liquid circulating pump by restraining, described absorption liquid circulating pump is connected with Water spray device by restraining.
Described tower emission-control equipment, described centrifugal fan is connected with ventilation blower shock mount, and described ventilation blower is covered with ventilation blower acoustic hood.
nullThe processing method of described tower emission-control equipment is，First exhaust emission source collecting pit collects waste gas，Through hood, waste gas is sent into absorption tower，Unabsorbed sour gas continues to ascend into first order spray section，The countless tiny absorption liquid mist formed by nozzle in spray section is dripped and is contacted with gas mixing，Proceed chemical reaction，Then go up second level packing section、Spray section，Carry out the processing procedure same with the first order，The second level is different from first order spray nozzle density，Spray liquid pressure is different，The intensity of absorption reaction and scope are also different，In spray section and filling surface gas-liquid two-phase haptoreaction process，It it is the process of heat and mass transfer，The abundant and stable of this process is ensured by controlling void tower flow velocity and holdup time，For the sour gas that chemism is higher，Adopt neutral water to absorb and just can reach enough purification efficiencies，And for some activity poor material of activity，Still need and add a certain amount of surfactant in absorbing liquid，It is provided with mist section at tower body upper-part，The absorption liquid mist carried secretly in gas drops in and is eliminated here，Clean air after treatment enters air from purifying column upper end.
Beneficial effect:
1. the present invention designs a kind of tower emission-control equipment, the hydrochloric acid of discharge, nitric acid, sulphuric acid, tail gas and oxysulfide, nitrogen oxides, the cyanide etc. such as Fluohydric acid. in the industry production processes such as chemical industry, light industry, printing and dyeing, medicine, machinery, electronics, instrument, iron and steel, adopt this equipment, be all up satisfied purified treatment effect.Tower for purifying waste gas adopts 2 grades of inversely spraying, 2 grades of packing material absorbings process techniques, the gas liquid ratio determined by experimentation, the absorption fluid component according to the preparation of waste gas main component, ensure that the stable operation of absorption reaction, the purification efficiency of all kinds of acid waste gas all can be reached 85～95%.Adopt efficiently except mist design, overcome the entrainment phenomenon that tradition spray column is common, not only contribute to environmental conservation, not reduce further absorption liquid increment.This equipment by tower body, absorb liquid bath, circulating pump, absorption liquid tubing are combined into the equipment of complete set, compact conformation, it is simple to in-site installation and operation management, floor space is less, is arranged on ground or roofing board and all has clear superiority.
