Description

Technical Field

[0001] The utility model relates to the technical field of spray towers, in particular to a circulating water tank for a spray tower with an automatic spray liquid replacement structure. Background Art

[0002] The spray tower exists as a treatment equipment for environmental waste gas treatment. According to the working principle, it is divided into circulating water spray tower, alkali spray tower, and acid spray tower. According to the tower body material, it is divided into FRP spray tower, PP spray tower, and stainless steel spray tower. Choose reasonable spray material and spray process according to the different properties of waste gas;

[0003] Its working principle is to use chemical agents to treat waste gas in order to achieve the purpose of waste gas purification and deodorization; when the gas containing pollutants passes through the packing layer, the pollutant molecules and tiny dust in the gas will be intercepted and blocked by the liquid film on the packing, and the pollutant molecules will be transformed from gas phase to liquid phase, and react with the effective molecules in the liquid phase, so as to be adsorbed, decomposed and filtered out. The water after spraying will directly fall into the circulating water tank at the bottom of the spray tower body for recycling.

[0004] When using a conventional circulating water tank, the solution in the spray tower needs to be manually replaced regularly, which will affect the exhaust gas treatment effect inside the spray tower. At the same time, when the spray liquid needs to be replaced according to different treatment needs, manual operation is also required, which makes the overall operation time-consuming and labor-intensive, and prone to structural leakage.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a circulating water tank for a spray tower with an automatic spray liquid replacement structure is proposed. Utility Model Content

[0011] Furthermore, the external valve pipe is installed at the lower end of the side of the liquid collecting box, and the filter box is fixed to the inner bottom side of the liquid collecting box.

[0012] Furthermore, the drainage assembly includes an assembly seat, a docking valve tube, a centrifugal pump and a liquid extraction pipe. A docking valve tube is installed on the top of the assembly seat, and the centrifugal pump is connected to the side of the docking valve tube close to the liquid collecting tank, and the end of the centrifugal pump away from the docking valve tube is connected to the liquid extraction pipe.

[0013] Furthermore, the liquid extraction pipe is arranged inside the liquid collecting box, and the centrifugal pump is fixed to the lower end of the side of the liquid collecting box.

[0014] Furthermore, the liquid exchange assembly is symmetrically installed on the left and right sides of the liquid collecting box, and the liquid discharge assembly is arranged between the front and rear liquid exchange assemblies.

[0015] The utility model provides a circulating water tank for a spray tower with an automatic spray liquid replacement structure, which has the following beneficial effects:

[0016] 1. The utility model has four groups of liquid changing components symmetrically arranged on the side of the liquid collecting box, wherein different spray liquids are injected into each liquid changing box by means of a liquid inlet. Therefore, when one of the liquids is needed, the spray liquid in the liquid changing box is extracted by means of a two-way pump in cooperation with the operation of a control valve, and is injected into the liquid collecting box through a delivery pipe. When the spray liquid in the liquid collecting box needs to be replaced, the spray liquid currently collected in the liquid collecting box is extracted by means of a delivery pipe through the operation of a two-way pump, and is delivered to the liquid changing box of the corresponding component, and then the liquid changing operation is performed under the operation of another group of liquid changing components. By using the above structure, the flexibility of use of the liquid collecting box is effectively guaranteed, so that it can be flexibly operated according to different use needs, thereby achieving different purification treatment effects on the exhaust gas.

[0017] 2. The utility model adopts a circulation component symmetrically installed at the front and rear ends of the liquid collecting box, wherein only the downstream spray device needs to be connected with an external valve pipe. When the circulation component is in operation, as the suction pump installed at the bottom of the liquid collecting box by the fixed frame operates, the spray liquid in the liquid collecting box will be collected from the filter tube, wherein the filter tube will preliminarily filter the spray liquid, and then the spray liquid will be further transported to the interior of the filter box for further filtering treatment, and then enter the downstream spray device under the transmission of the external valve pipe and re-enter the spray tower for recycling. By using the above structure, on the one hand, by arranging the circulation component inside the liquid collecting box, the liquid collecting box can be effectively used to provide structural protection for the circulation component to prevent the liquid from directly leaking into the external environment when the circulation component has structural leakage, causing pollution and waste of spray liquid. On the other hand, it can effectively ensure the filtering and purification effect of the spray liquid, so as to better recycle the spray liquid. BRIEF DESCRIPTION OF THE DRAWINGS
