Description

Technical Field

[0001] The utility model relates to the field of waste gas treatment, and more specifically, to a spray tower structure based on waste gas treatment. Background Art

[0002] The spray tower is an important equipment for treating flue gas in factories. The acidic or alkaline acid mist waste gas is introduced into the purification tower through the air duct, passes through the packing layer, and is sent into the tower from the bottom. After being distributed by the gas distribution device, it continuously passes through the gaps of the packing layer in countercurrent with the sodium hydroxide absorption liquid. On the surface of the packing, the gas and liquid phases fully contact and absorb the neutralization reaction to adsorb the acidic or alkaline pollutants contained in the waste gas. After the acid mist waste gas is purified, it is dehydrated and defogged by the demister plate, and the clean gas is discharged from the fan into the atmosphere. Insoluble viscose particles and dust are discharged into the collection tank, suspended particles go out from the overflow port, and the collected sediment is discharged from the sewage outlet. The absorption liquid is pressurized by the water pump at the bottom of the tower and sprayed down at the top of the tower, and finally refluxed to the bottom of the tower for recycling. In the current use process, the first and second layer spray systems of the spray tower mostly use two sets of pressurized spray devices. Therefore, the equipment cost and maintenance cost of the pressurized feeding device are high during use, and the energy consumption and redundant waste are large.

[0003] The utility model with authorization announcement number CN214635352U discloses a spray tower for waste gas treatment, including a spray tower, an air inlet pipe, an air outlet pipe and a packing layer, wherein one side of the bottom end of the spray tower is connected to an air inlet pipe, the top layer of the spray pipe is connected to an air outlet pipe, the packing layer is installed on the top layer of the spray tower, a washing layer is arranged in the spray tower, a second washing layer is arranged in the spray tower and located above the first washing layer, and a return water treatment tank is arranged below the spray tower. The utility model relates to the technical field of waste gas treatment. The spray tower for waste gas treatment has a simple structure and is easy to operate. A single-group plunger pump is used as a power source. The spray water is controlled by adjusting the water diversion component to control the pressure and flow rate of the water flow, and the adjusted diversion is respectively passed into the first washing layer and the second washing layer, thereby reducing the cost of the equipment and the subsequent maintenance cost, and saving the operating cost of the equipment.

[0004] In the above-mentioned disclosed structure, the spray structure is fixedly installed inside the spray tower and cannot be adjusted flexibly, which affects the uniformity of the spray and is not conducive to operation and control. Moreover, when the water supply is large, it cannot automatically flow back, resulting in a large spray water pressure, affecting the exhaust gas discharge effect and being not conducive to treatment. Improvements are needed. Utility Model Content
