Description

Technical Field

[0001] The invention belongs to the technical field of waste gas treatment equipment, and in particular relates to a highly efficient and energy-saving waste gas washing equipment. Background Art

[0002] Waste gas refers to toxic and harmful gases discharged by humans in the process of production and life, especially from chemical plants, steel mills, pharmaceutical plants, coking plants and refineries. The waste gas emitted has a strong odor, seriously pollutes the environment and affects human health. Therefore, a scrubber is usually used to treat the waste gas before it is discharged.

[0003] A scrubber is a device used to treat harmful substances in industrial waste gas or exhaust gas. It is also called an absorption tower or tower absorber. It usually consists of a tower body, packing (or tower plate), a spray system, an air inlet, an air outlet, etc. When the scrubber is working, the waste gas enters the waste gas tower tangentially from the air inlet below the tower body. Under the power of the fan, it quickly fills the lower space in the tower and then rises evenly through the flow-equalizing section to the first-stage packing absorption section; on the surface of the packing, the acidic substances in the gas phase react chemically with the alkaline substances in the liquid phase; the reaction products (mostly soluble salts) flow into the lower liquid tank with the absorption liquid; the waste gas that is not completely absorbed continues to rise into the first-stage spray section, where the absorption liquid is sprayed out at high speed from the uniformly distributed nozzles, forming countless fine droplets that fully mix and contact with the gas and continue to react chemically; then the acid gas rises to the second-stage packing section and spray section to undergo an absorption process similar to the first stage.

[0004] The commonly used fillers in the washing tower are multi-faceted hollow plastic spherical fillers. The spherical fillers are evenly filled on the mesh plate, and the gas and liquid contact and react at the spherical fillers. After the exhaust gas tower has been working for a long time, impurities are attached to the fillers, causing some fillers to stick together. Some harmful substances in the exhaust gas are directly discharged without fully reacting with the substances on the filler area, and the quality of exhaust gas treatment is low, which in turn affects the working efficiency and exhaust gas treatment effect of the washing tower; in addition, after the exhaust gas tower has been working for a long time, the spherical fillers need to be cleaned or replaced, that is, a window is set on the outside of each layer of fillers to replace the fillers. Workers need to use an escalator to take out the fillers from the window and replace them. Since the fillers are only taken out from the window, they also need to be refilled into the spray tower from the window, which is very inconvenient for workers to quickly replace the fillers, further reducing the working efficiency of the washing tower. Therefore, it is urgent to design an efficient and energy-saving exhaust gas washing equipment to solve the above problems. Summary of the invention

[0045] Working principle:

[0046] During operation, the exhaust gas enters the air inlet cylinder 19 from the air inlet 20, and quickly fills the air inlet cylinder 19 under the power of the ventilator, and flows into the cyclone cylinder 5. Under the cyclone action of the dust reduction component 3 and the cyclone plate 4, the exhaust gas is subjected to dust reduction treatment. At the same time, under the spraying action of the spray structure 6, countless fine droplets are mixed and contacted with the gas, and a chemical reaction can occur while removing dust. Then the exhaust gas rises to the packing absorption section between the first-stage packing support plate 7 and the packing cover plate 9; on the surface of the packing, the acidic substance in the gas phase reacts chemically with the alkaline substance in the liquid phase, and the reaction product flows into the lower waste liquid collection box 2 with the absorption liquid; the exhaust gas that is not completely absorbed continues to rise and enters the first-stage spray section between the spray structure 6 and the packing cover plate 9, and the absorption liquid is sprayed out at a high speed from the uniformly distributed nozzles 6-1 in the spray section, forming countless fine droplets that are fully mixed and contacted with the gas, and continue to react chemically; then the acid gas rises to the second-stage packing section and the second spray section to undergo an absorption process similar to the first stage;

[0047] After working for a period of time, the motor in the rotary drive assembly 14 and the lifting drive motor 12-4 in the reciprocating drive assembly 12 are started regularly to drive the spline shaft 18 to rotate and reciprocate and lift, thereby driving the stirring and disturbing mechanism 16 to rotate and reciprocate and lift, so as to achieve the purpose of breaking up the filler and avoid that part of the filler is adhered together after a long time, thereby affecting the working efficiency and exhaust gas treatment effect of the washing tower; in the stirring and breaking process, under the action of the material pressing elastic component 10, the filler cover plate 9 is elastically pressed downward, thereby compacting the filler;

[0048] When the packing needs to be replaced, the electric push rod 22-7 in the valve plate device 22 is started, and then the discharge port opened on the packing support plate 7 is opened, and the packing slides along the discharge chute 17 to the open packing outlet 21 for discharge, and the rotating stirring disturbance mechanism 16 can speed up the packing discharge speed; after the packing is emptied, the staff can fill the packing from the packing inlet 8 to the space between the packing support plate 7 and the packing cover plate 9. At this time, the rotating and reciprocatingly lifting and lowering stirring disturbance mechanism 16 can ensure that the packing is evenly distributed between the packing support plate 7 and the packing cover plate 9, thereby realizing the rapid replacement of the packing.
