Description

Technical Field

[0001] The present application belongs to the technical field of waste gas treatment, and in particular relates to an organic waste gas treatment device used for thermal hydrolysis of organic waste. Background Art

[0002] Thermal hydrolysis of organic waste is a pretreatment technology mainly used to treat sludge and organic waste. This technology mixes sludge or organic waste with steam waste heat and performs thermal hydrolysis reaction under high temperature and pressure to improve the hydrolysis and digestion efficiency of sludge.

[0003] In the thermal hydrolysis reaction, some organic matter in organic waste will volatilize or decompose to form organic waste gas, which may contain volatile organic compounds (VOCs), odorous substances, etc. Molecular sieve is one of the excellent VOCs adsorbents, with a large specific surface area and micropore volume, and a strong adsorption capacity for polar molecules such as water. It is often used in the treatment of organic waste gas, but the adsorption capacity of molecular sieve is limited, so the molecular sieve needs to be replaced regularly. However, most of the molecular sieves are replaced and cleaned regularly. When the ventilation volume is large, the amount of organic waste gas adsorbed is also large. If the regular replacement method is adopted, it is easy to cause the molecular sieve to be replaced untimely, affecting the treatment quality of organic waste gas. Utility Model Content

[0012] Compared with the prior art, the present application provides an organic waste gas treatment device for hot hydrolysis of organic waste, having the following beneficial effects:

[0013] 1. For the organic waste gas treatment device for hot hydrolysis of organic waste, through the provided processing shell and end cover, a molecular sieve is fixed in the processing shell through a filter screen frame. The intake pipe conveys the organic waste gas into the processing shell, and the impurities in the organic waste gas are adsorbed and treated through the adsorption effect of the molecular sieve, and then discharged through the exhaust pipe. The stable sealing connection between the end cover and the processing shell is realized through the matching insertion of the sealing insertion frame and the sealing insertion groove. Then, through the matching clamping of the T-shaped clamping block and the T-shaped clamping groove, the locking block firmly clamps and limits the processing shell and the end cover. At this time, the clamping rod is aligned with the clamping groove, and the clamping spring pulls back the clamping pull plate.

The transmission shaft cooperates with the reduction gearbox to drive the reciprocating lead screw to rotate in the trigger shell. Through the threaded socket connection between the reciprocating lead screw and the trigger plate, the trigger plate moves in the trigger shell. Then, after a period of time, the trigger plate acts on the trigger switch, and the trigger switch controls the warning device to sound, reminding the staff to replace the molecular sieve to ensure the continuous treatment quality of the organic waste gas. Moreover, the more and faster the organic waste gas is introduced, the shorter the interval time for the trigger plate to act on the trigger switch. It can roughly judge the adsorption degree of the molecular sieve based on the automatic feedback of the treatment speed of the organic waste gas, making the replacement of the molecular sieve relatively more accurate.
