Embodiment 1

[0032] Such as figure 1 As shown, the organic waste gas biological filtration tower includes a tower body 1, and the tower body 1 is sequentially provided with a water storage layer 10 and a biodegradation layer 11 from bottom to top. The top of the tower body 1 is provided with an exhaust port 15. The water outlet is connected to the water source, and the outlet of the water storage layer 10 is connected to the water treatment system. The water storage layer 10 is built with an air distribution device 100, and the air distribution device 100 is preferably an aeration plate, and the air inlet of the air distribution device 100 passes through a pipe equipped with a fan Connect the exhaust gas source, the tower body 1 is provided with a spray assembly 13, the spray assembly 13 is located above the biodegradable layer 11, the spray assembly 13 includes a bracket installed in the tower body 1, and an installation pipe is installed on the bracket. The pipe is provided with several ...

Embodiment 2

[0038] The difference between the present embodiment and the first embodiment lies in the structure of the biodegradable layer 11, such as figure 2 and image 3 Commonly shown, the biodegradable layer 11 includes a cylinder 2 arranged horizontally. The cylinder 2 is an integrally formed part of the tower body 1. A first hollow shaft 20 is coaxially installed in the cylinder 2. On the first hollow shaft 20, a There are several through holes 200, the several through holes 200 are arranged at intervals along the axial direction of the first hollow shaft 20, and are arranged in a circle around the axis of the first hollow shaft 20, and the first hollow shaft 20 is connected with The mesh cylinder 21 of degradable filler, the mesh cylinder 21 clearance fits in the cylinder 2, the outer wall of the mesh cylinder 21 and the inner wall of the cylinder 2 are provided with a nylon sleeve, and one end of the first hollow shaft 20 is rotatably connected to the cylinder 2, The other end ...

Abstract

The invention discloses a biofilter for organic waste gas. The invention relates to the technical field of waste gas treatment devices. The tower comprises a tower body, wherein the tower body is sequentially provided with a water storage layer and a biodegradation layer from bottom to top; wherein an exhaust port is formed in the top of the tower body, a gas distribution device is arranged in thewater storage layer, a gas inlet of the gas distribution device is connected with a fan, a spraying assembly is arranged in the tower body, the spraying assembly is located above the biodegradation layer, and the spraying assembly is connected with the water storage layer through a first liquid inlet pipeline provided with a circulating water pump. The technical problem that in the prior art, theorganic waste gas filtering efficiency is poor is solved. A three-stage waste gas filtering stage is adopted, the filtering efficiency and effect of organic waste gas are greatly improved, meanwhile,the manufacturing cost is reduced, the economic benefits are improved, and the device further has the functions of maintaining the efficient filtering performance of the biodegradation layer, periodically cleaning the biodegradation layer, controlling the water content and the like.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment devices, in particular to a biological filter tower for organic waste gas. Background technique [0002] At present, the devices that use biological filtration technology to treat organic waste gas mainly include biological filter beds and biofilm packed towers. Fill active fillers, such as soil, peat, sawdust, chaff, etc. Microorganisms that can degrade pollutants grow in the fillers, and the exhaust gas is purified when passing through the filler layer. The problem with the biological filter bed is that during long-term operation, due to the compaction of the packing, the filter bed will be blocked, the pressure drop will increase, and the performance will decrease. The biofilm packed tower can maintain stable performance for a long time. It uses inert materials as packing ( Such as gravel, plastic particles, ceramics, carbon fiber, etc.), the circulating nutrient solution is spraye...
