Description

Technical Field

[0001] This application relates to the field of waste gas treatment equipment technology, and in particular to a horizontal spray tower. Background Technology

[0002] Spray towers are a commonly used purification equipment for waste gas purification and filtration. Their principle is to use a fan to draw waste gas into the tower, which then flows through the packed layer (the medium for gas / liquid contact reaction), allowing the waste gas to fully contact the liquid flowing on the packed surface to adsorb acidic or alkaline pollutants contained in the waste gas. In horizontal spray towers, the waste gas passes through the equipment horizontally and comes into contact with the vertically downward liquid to achieve the purification treatment of the waste gas.

[0003] Currently, the spray liquid in spray towers is recycled to save on operating costs. However, after prolonged use, the spray liquid becomes mixed with particulate impurities due to contact with exhaust gas, which can easily clog the pipeline during the circulating flow of the spray liquid. Furthermore, existing spray towers lack the function of filtering the circulating spray liquid, thus affecting the actual use of the spray tower. Utility Model Content

The circulation component includes a water tank located outside the tower body. The water tank is connected to the liquid collection tank. A detachable filter assembly is provided inside the water tank. A circulation pump is also provided inside the water tank. The circulation pump is used to pump the spray liquid filtered by the filter assembly into the spray pipe through the circulation pipe.

[0008] Furthermore, the water tank is equipped with a water storage chamber and an equipment chamber. The filter assembly can be pulled out and installed in the water storage chamber. When the filter assembly is installed in the water storage chamber, it is used to divide the water storage chamber into a first chamber and a second chamber. The first chamber is connected to the liquid collection tank through a connecting pipe. A dosing pipe connecting to the second chamber is opened on the upper side wall of the water tank.

[0015] Compared with the prior art, the application has the following beneficial effects:

[0016] 1. By arranging the detachable filtering assembly in the water tank, the filtering assembly can filter the circulating spray liquid, so as to avoid that the particles in the spray liquid block the spraying assembly and affect the working of the spraying assembly. In addition, the filtering assembly can be disassembled and cleaned, so as to ensure the filtering effect of the filtering assembly.

[0017] 2. By arranging the dosing pipe and the stirring assembly, the stirring assembly can stir the spray liquid in the second chamber along with the circulation of the spray liquid, so as to mix the medicament with the spray liquid quickly, and ensure the treatment effect of the circulating spray liquid on the exhaust gas.

When the filter assembly 320 is installed in the water storage compartment, the water storage compartment is divided into a first chamber 401 and a second chamber 402. The first chamber 401 communicates with the liquid collecting groove through the connecting pipe 302. The upper side wall of the water tank 110 is provided with a dosing pipe 331 communicating with the second chamber 402. The second chamber 402 is provided with a stirring assembly.

[0041] In the embodiment, the spray liquid collected in the liquid collecting groove can enter the water storage compartment through the connecting pipe 302. After being filtered by the filter assembly 320, the spray liquid entering the second chamber 402 is filtered, so that the filtered spray liquid is pumped into the spray pipe 220 by the circulating pump 310 to perform the spraying operation.

[0042] The pullable arrangement of the filter assembly 320 makes it possible to pull out the filter assembly 320 and clean the filter assembly 320 when the filter assembly 320 is blocked due to long-time filtering, so as to ensure the filtering effect.
