Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to a deodorization device for environmental protection sludge treatment. Background Technique

[0002] At present, in the deodorization equipment on the market, during the work of purifying and deodorizing odors, due to the lack of an air flow pressure reduction mechanism, often because the air flow pressure is relatively large during the transportation of odors, the odor purification is not thorough, which is likely to cause secondary pollution to the environment, or because the odor treatment does not meet the standards and needs to be deodorized and purified again, resulting in low deodorization and purification efficiency.

[0003] Publication No. CN218501692U discloses a low-temperature plasma deodorization device for a sludge treatment plant, including a sludge treatment tank. A blower is installed in the middle of the top of the sludge treatment tank. A washing and buffering tank is installed on one side of the sludge treatment tank. A low-temperature plasma deodorizer is installed at the bottom of the washing and buffering tank. A filter box is installed on one side of the low-temperature plasma deodorizer. This device provides driving force through a blower. Through the cooperation of the washing and buffering tank, the limiting partition board, the air guiding cover, the pressure relief driving fan, the hollow air distribution head and the connecting frame, the pressure of the odor can be effectively relieved, so that the odor can be smoothly carried out for subsequent odor treatment work, and the washing and buffering tank, the low-temperature plasma deodorizer and the filter box can carry out more comprehensive and thorough odor purification work on the odor, effectively improving the deodorization quality and efficiency, and effectively avoiding incomplete odor purification caused by large air flow pressure and secondary pollution to the environment. However, the following problems still exist in the actual use of this patent:

[0004] The odor in the above device lacks pretreatment after being extracted, and the impurities in the odor will directly enter the low-temperature plasma deodorizer. When the existing low-temperature plasma deodorizer deodorizes, the impurities mixed in the air flow will increase the equipment burden, and the above device mainly decelerates the air flow through the pressure relief driving fan, but the pressure relief efficiency of a single pressure relief driving fan for the air flow is relatively low.

[0005] A deodorization device for environmental protection sludge treatment is proposed to solve the problems raised above. Content of the Utility Model

[0035] Working principle: Before using the deodorization device for a kind of environmentally friendly sludge treatment, it is necessary to first check the overall situation of the device to determine that it can work normally. According to Figure 1 - Figure 5 As shown, first, the odor is drawn into the connection shell 202 through the first conduit 103 by the air extraction device 102. At this time, the high-speed air flow will blow the deceleration drive fan 205 to rotate, so that the hollow column 203 rotates, and then the connecting rod 207 drives the scraping rod 208 to rotate;

[0036] The air flow will enter the hollow column 203 through the air inlet groove 204, and then escape through the air outlet holes 206 to form bubbles in the water body, thereby greatly reducing the air flow speed. As the connecting rod 207 rotates, the bubbles will be disturbed and broken, so that the impurities inside the bubbles will be mixed into the water body. Eventually, when the bubbles float and leave through the air outlet pipe 212, the impurities in the bubbles will be reduced, and finally the multi-layer pressure relief, deceleration and pre-removal of impurities of the odor are realized;

[0037] The scraping rod 208 can reduce the attachment of impurities on the inner wall of the flow reduction box 201;

[0038] The air flow of the air outlet pipe 212 will blow a number of deceleration fans 303 to rotate, realizing the secondary deceleration of the air flow. The contact between the deceleration fans 303 and the low-speed odor will make the impurities in the odor easily attach to the deceleration fans 303. By pressing the pressing column 306, the vertical plate 307 can drive the clamping head 308 to disengage from the clamping groove 309, and finally the deceleration fans 303 are easy to disassemble and maintain;

[0039] The water body is discharged by opening the water valve on the exchange pipe 211, and the exchange pipe 211 is also used to re-inject water;
