Abstract
A smoke multilevel wet dust-removal decontamination device is composed of a plurality of decontamination chambers which are the same in structure in series. Each decontamination chamber is filled with specific dissolvent. A water outlet pipe (2) is arranged at the bottom of each chamber, a smoke inlet pipe (1), a water outlet pipe (3) and a smoke outlet pipe (5) are arranged on a top cover of each chamber, and a sieving screen (6) and a water spray nozzle (4) are arranged inside the smoke outlet pipe. Solid particles in smoke can be freely settled in solution after closely contacting with the solution, and therefore the purpose of dust-removal can be achieved. Throughchemical reaction between the dissolvent in the decontamination chambers and harmful gases in the smoke, the purpose of decontamination can be achieved. The smoke multilevel wet dust-removal decontamination device has the advantages of being simple in structure, small in occupied area, convenient to operate and maintain, high in decontamination efficiency, and capable of processing high-temperature and high-humidity airflow and removing some gaseous pollutant, and therefore the purpose of decontaminating the gases can be achieved.
Description
Technical field
The utility model relates to technical field of waste gas treatment, relates in particular to a kind of multistage wet dust removal purifier.
Background technology
Flue gas is the mixture of gas and flue dust, is the main cause of atmosphere pollution.The composition of flue gas is very complicated, comprises SO in the gas
2, CO, CO
2, hydrocarbon and oxynitrides etc., flue dust comprises ash content, coal grain, mineral grain of fuel etc.
Deduster commonly used is separated flue dust in boiler and the commercial production from flue gas, reaches the effect of cleaning of off-gas.Deduster is divided into dry collector, half dry type deduster, wet scrubber according to dedusting method.Use in the industry now many be dry bag formula deduster.
Filter bag in the sack cleaner is easy blocking in use, shortens the life-span, and the pressure loss rises significantly simultaneously, and efficiency of dust collection reduces.Deduster is connected with the exhaust apparatus of Industrial Stoves usually, and high-temperature flue gas makes the filter bag distortion damaged easily.
Wet scrubber is that flue gas is contacted with liquid (being mostly water) closely, utilizes the inertial collision of water droplet and particle and the device that other effect captures particle.Existing wet scrubber commonly used is the spray form, utilizes the water curtain depositing dust.Above-mentioned dust arrester only can filter the solid particle in the flue gas, and dust-laying effect is not good, to containing S0
2Flue gas Deng pernicious gas can not play catharsis.
The utility model content
The purpose of the utility model is exactly in order to solve the defective of existing dust arrester dust removing effects difference, the multistage wet dust removal purifier of a kind of flue gas that provides.
The technical scheme that the utility model adopts is following:
The multistage wet dust removal purifier of a kind of flue gas; It is characterized in that this device is composed in series by at least two identical clean rooms of structure; The bottom of each clean room is provided with drainpipe, and the top of each clean room is respectively equipped with air inlet pipe, water inlet pipe and blast pipe, and the blast pipe of prime clean room is connected with the air inlet pipe of back level clean room; Be marked with the liquid flux that absorbs flue gas in each clean room, the air inlet pipe mouth of pipe immerses in the clean room below the liquid flux liquid level.In addition, be provided with screen cloth and water spout in the blast pipe, water spout is positioned at directly over the screen cloth.
The utility model contacts with solution through the solid particle in the flue gas closely, and natural subsidence in solution reaches the effect of depositing dust, reaches the purpose of purification through solvent in the clean room and the pernicious gas generation chemical reaction in the flue gas.
The utlity model has simple in structure, floor space is little, operation and easy to maintenance and purification efficiency advantages of higher, can handle the air-flow of high temperature, high humidity, also can remove the part gaseous contaminant, plays the effect of Purge gas.
Description of drawings
Fig. 1 is the multistage wet dust removal purifier of a kind of flue gas of a utility model sketch map.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, the multistage wet dust removal purifier of a kind of flue gas that the utility model provides is composed in series by three identical clean rooms (A, B, C) of structure.Charge into the desulfurizing agent (alkaline solution of calcium carbonate medicament configuration) that accounts for clean room's volume 80% in each clean room; Drainpipe 2 is arranged at the bottom, clean room; Air inlet pipe 1, water inlet pipe 3, blast pipe 5 are arranged on the top, chamber, clean room, and the blast pipe 5 of prime clean room is connected with the air inlet pipe 1 of back level clean room.Be provided with screen cloth 6 and water spout 4 in the blast pipe.The air inlet pipe mouth of pipe immerses in the clean room below the liquid flux liquid level.Be provided with screen cloth 6 and water spout 4 in the blast pipe, water spout is positioned at directly over the screen cloth.
To be mixed with SiO
2Particle and SO
2The flue gas of pernicious gas guarantees that from air inlet pipe 1 A of feeding clean room the air inlet pipe mouth of pipe immerses below clean room's internal solvent liquid level.Solid particle in the flue gas contacts with solvent closely, is deposited in wherein SO
2Gas forms CaSO under the effect of desulfurizing agent
4, be deposited in the clean room.The blast pipe of the A of clean room links to each other through flange 7 with the air inlet pipe of the B of clean room, and the flue gas of process preliminary purification feeds the B of clean room and carries out 2 purifications, feeds the C of clean room according to this again and carries out 3 purifications.
Screen cloth 6 is installed on the blast pipe mouth of pipe of the A of clean room, and the bulky grain solid that reduces in the flue gas gets into next clean room with air-flow.Water spout 4 be installed in screen cloth 6 directly over, can wash screen cloth, prevent to stop up.
Outlet pipe 2 is installed on the bottom of clean room, is used to discharge saturated solvent.Water inlet pipe 3 is installed on clean room's top cover, is used for the solvent that after-purification is used.
Through monitoring in continuous 2 days, this device exhaust outlet particle concentration and SO
2Content meets " discharge standard of air pollutants " (GB16297) secondary standard.
The utility model is simple in structure, floor space is little, operation and easy to maintenance, and purification efficiency is high, can handle the air-flow of high temperature, high humidity, also can remove the part gaseous contaminant, plays the effect of Purge gas.
The foregoing description only is the preferred embodiments of the utility model; The technical conceive and the essential implementation of the utility model have been specified; Be not to be that protection domain to the utility model limits; All any simple modification and equivalent structure transformation or modifications of being done according to the utility model spirit all should be encompassed within the protection domain of the utility model.
