Round, ellipse expands any one in cylinder；Obstruction catching net is using in installation outside installation in nozzle or nozzle
Any one.
Sulfur-bearing (sulphur steam, hydrogen sulfide, sulfur dioxide etc.) tail gas (air, which enters, keeps tail gas oxygen-containing) that gas gathering mask is collected, warp
Be mounted on pipeline opening obstruction catching net capture wherein most sulphur steam after, enter digester along pipeline, digester lower part into
Gas is tangential manner, and gas its solid, liquid body carried after eddy flow is separated, uniformly leads to after gas distributor is uniformly distributed
Desulfurizing agent filler is crossed, the gas after desulfurization is emptied through air exhauster.Digester top is equipped with the valve on thermometer and nitrogen pipeline
Door is chain, and when thermometer data is more than 100 DEG C, valve opening, the oxidation reaction being passed through on nitrogen prevention desulfurizing agent, is desulfurization
Agent cooling；When thermometer data is less than 80 DEG C, valve is closed.Sulphur steam is by stopping catching net, pipeline, cyclonic separation, porcelain
Ball is removed substantially after capturing.
The beneficial effects of the present invention are: 1, sulfur-bearing of the present invention (sulphur steam, hydrogen sulfide, sulfur dioxide etc.), oxygen-containing tail gas
Treatment process, handicapping block catching net, eddy flow entrance, porcelain ball and capture equipment, substantially eliminate into sulphur steam in the tail gas of desulfurizing agent
Amount, improves the desulfuration efficiency of desulfurizing agent.
2, sulfur-bearing (sulphur steam, hydrogen sulfide, sulfur dioxide etc.) of the present invention, oxygen-containing tail gas treatment process on digester top
Chain equipped with the valve on thermometer and nitrogen pipeline, when thermometer data is more than 100 DEG C, valve opening is passed through nitrogen resistance
The only oxidation reaction on desulfurizing agent cools down for desulfurizing agent；When thermometer data is less than 80 DEG C, valve is closed, and restores normal behaviour
Make.Such design can protect desulfurizing agent, increase safety.
