Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization spray towers, in particular to a desulfurization spray tower with high-efficiency dust removal. Background Art

[0002] Industrial production often generates a large amount of waste gas that needs to be treated by spray towers. Waste gas treatment refers to the pretreatment of waste gas generated in industrial sites and factory workshops before external discharge to meet national standards for waste gas discharge. Spray towers are commonly used equipment for industrial dust removal or waste gas treatment.

[0003] For example, the Chinese patent number CN216136992U is a desulfurization spray tower with efficient dust and mist removal functions. In this utility model, a pressurizing mechanism is used to allow the treated exhaust gas to enter a water tank for secondary treatment. However, this utility model uses a lifting structure to pressurize and cooperates with an elastic mechanism to reset. In actual use, the resetting of the elastic mechanism takes a certain amount of time, which will cause water leakage inside the water tank, thereby affecting the desulfurization treatment operation. At the same time, this utility model cannot recycle spray water, resulting in a huge water consumption of the spray tower, which is not conducive to user use. Therefore, a desulfurization spray tower with efficient dust removal is proposed to solve the above problems. Utility Model Content

[0027] exist Figure 2 In the embodiment, a spray chamber 403 is provided inside the shell 1, and a water storage chamber 404 is provided inside the shell 1, so that two completely separated chambers are formed inside the shell 1, thereby improving the sealing performance of the exhaust gas treatment structure.

[0028] exist Figure 2 In the embodiment, a shunt pipe 405 is installed on the inner top wall of the spray chamber 403, and a nozzle below is used to spray water to the waste gas entering the spray chamber 403. A connecting pipe 406 is installed on the inner left wall of the water storage tank 401 to connect the spray chamber 403 and the water storage tank 401, so as to facilitate the circulation of water and filter the waste water.

[0029] exist Figure 2 and Figure 3 In the figure, a filter screen 407 is installed inside the connecting pipe 406 to intercept dust and large impurities in the wastewater from entering. A filter plate 408 is installed on the right side of the filter screen 407 to preliminarily filter the wastewater and reduce harmful substances.

[0031] It should be noted that this section is intended to provide a background or context for the implementation methods stated in the claims, and detailed descriptions of known functions and known components are omitted. At the same time, fixed and movable installations are determined according to actual application methods. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment. The description here is not admitted to be prior art because it is included in this section.

[0032] When implementing, follow these steps:

[0033] 1) First, start the water pump 402 to extract the water in the water tank 401 and transport it to the diversion pipe 405, spray it downward through the nozzle, and then transport the exhaust gas to the spray chamber 403 through the air inlet pipe 2, so that the exhaust gas contacts the water under the spray;

[0034] 2) Then, the treated gas will enter the vent pipe 410 through the waterproof vent valve 411, and then pass through the waterproof vent plug to enter the water storage chamber 404, so that the waste gas after the first treatment will contact the treated water in the water storage chamber 404 for further treatment;

[0035] 3) Finally, the sewage sprayed down is filtered through the filter screen 407, the filter plate 408 and the activated carbon filter cotton block 409, and then becomes clean water and returns to the water storage tank 401, waiting for the next use.

[0036] In summary, the desulfurization spray tower with high-efficiency dust removal completely separates the space inside the shell 1 by dividing the spray chamber 403 and the water storage chamber 404, thereby avoiding the risk of leakage of treated water inside the water storage chamber 404 and improving the sealing of the desulfurization spray tower. At the same time, by using the ventilation pipe 410, the waterproof ventilation plug and the waterproof ventilation valve 411, the internal gas of the spray chamber 403 and the water storage chamber 404 can circulate, and the waterproof ventilation valve 411 is set above the diversion pipe 405, so that only the exhaust gas treated by the spraying can enter the ventilation pipe 410, thereby improving the efficiency of exhaust gas treatment and making it convenient for users to use.

[0037] Moreover, by using the filter screen 407, the filter plate 408 and the activated carbon filter cotton block 409, the accumulated waste water falling from the spray is filtered to prevent dust from flowing back into the water storage tank 401, thereby improving the dust removal effect of the spray tower, reducing the water consumption required for spraying, and reducing the water consumption cost of the desulfurization spray tower, thereby facilitating the use of users. The water storage chamber 404 and the spray chamber 403 cooperate with each other to allow the incoming waste gas to undergo secondary treatment, further improving the waste gas treatment effect, and solving the problems of unstable sealing of the gas pipeline in the comparative documents, which leads to easy water leakage, and lack of wastewater recovery structure, resulting in huge water consumption.
