Description

Technical Field

[0001] This application relates to the field of gas purification, and in particular to a gas purification spray tower. Background Technology

[0002] In industrial production and environmental protection, gas purification technology is crucial. With the acceleration of industrialization, emissions of various waste gases are increasing daily, posing a serious threat to the environment and human health. Effective gas purification technology can reduce the emission of harmful gases, improve air quality, protect the ecological environment, and also help enterprises meet environmental regulations and achieve sustainable development. Gas purification equipment is constantly being upgraded to adapt to the treatment needs of different industries and different types of waste gases.

[0003] In traditional gas purification methods, spray towers are commonly used equipment. Traditional spray towers are typically designed with a multi-layered structure. When gas enters the tower, it needs to be sprayed through each layer multiple times by water jets to purify the gas. This multi-layered design requires the spray tower to have a considerable height and volume to accommodate the various spray layers and the gas flow space. Furthermore, to ensure effective spraying, it also requires large water pumps and complex piping systems.

[0004] However, this design of traditional spray towers has significant shortcomings. Due to their high requirements for height and volume, construction costs increase substantially, including site occupancy costs, building material costs, and equipment installation costs. Furthermore, their large size and complex structure lead to higher energy consumption during operation and increased maintenance difficulty. Moreover, traditional spray towers are unsuitable for locations with limited space. Utility Model Content

[0005] In order to reduce the operating cost of spray towers, this application provides a gas purification spray tower.

[0006] The gas purification spray tower provided in this application adopts the following technical solution:

[0007] A gas purification spray tower includes a main body, a purification cylinder, an air inlet device, and a spray device.

[0008] The purification cylinders are provided in multiple locations, all of which are located within the main body, with at least two purification cylinders distributed horizontally.

[0009] The air intake device is used to deliver gas into the purification cylinder.

[0010] The spraying device is used to spray purification liquid into the purification cylinder.

[0011] By adopting the above technical solution and setting up multiple horizontally distributed purification cylinders, the design of multi-layer structures is avoided, reducing the requirements for the height and volume of the spray tower, thereby reducing the cost of gas purification. Simultaneously, gas can be supplied to the purification cylinders through the air inlet device, and purification liquid can be sprayed into the purification cylinders using the spray device to achieve gas purification.

[0012] Preferably, it also includes defogging balls.

[0013] The demisting ball is located inside the main body and above all the purification cylinders.

[0014] The exhaust port of the main body is located above the defogging ball.

[0015] By adopting the above technical solution, the demisting balls located above all the purification cylinders are used to further treat the impurities such as mist in the gas, and finally the gas is discharged through the main exhaust port located above the demisting balls, thus achieving gas purification.

[0016] Preferably, it also includes a liquid storage tank.

[0017] The liquid storage tank is located below the purification cylinder.

[0018] The spraying device is also used to pump out the purified liquid in the storage tank.

[0019] By adopting the above technical solution, the spraying device sprays the purification liquid into the purification cylinder, and the purification liquid automatically flows into the storage tank below, realizing the recycling of the purification liquid.

[0020] Preferably, the spraying device includes a pump body, pipelines, and spray nozzles.

[0021] The pump body is used to draw purified liquid from the storage tank.

[0022] The pipeline is connected to the liquid outlet of the pump body.

[0023] The nozzle is provided in multiple parts and is connected to the pipeline. The nozzle is used to spray the purification liquid into the purification cylinder.

[0024] By adopting the above technical solution, the pump body draws the purified liquid from the storage tank and transports it through pipelines to multiple nozzles. The nozzles then spray the purified liquid into the purification cylinder, thereby achieving the purification of the gas in the purification cylinder and the recycling of the purified liquid.

[0025] Preferably, all the purified liquid sprayed from the nozzle flows into the purification cylinder.

[0026] By adopting the above technical solution, it is ensured that the purification liquid fully acts on the gas inside the purification cylinder, thereby improving the purification efficiency.

[0027] Preferably, the nozzle of the spray head is located inside the purification cylinder.

[0028] By adopting the above technical solution, it is ensured that all the sprayed purification liquid flows into the purification cylinder, effectively purifying the gas inside the purification cylinder.

[0029] Preferably, the air intake device includes a main pipe and branch pipes.

[0030] The branch pipe is provided in multiple parts, one end of the branch pipe is connected to the main pipe, and the other end of the branch pipe is connected to the purification cylinder.

[0031] By adopting the above technical solution, the gas can be distributed to various branch pipes through the main pipe and then enter different purification cylinders, realizing simultaneous gas intake and purification of multiple purification cylinders. This avoids the traditional method of using multi-layer spray towers that require spray purification layer by layer, reduces the requirements for the height and volume of the spray tower, and thus reduces the purification cost.

[0032] Preferably, the connection between the branch pipe and the purification cylinder is located at the lower part of the purification cylinder.

[0033] By adopting the above technical solution, the gas enters the purification cylinder from the bottom, which facilitates the spraying device to spray the purification liquid into the purification cylinder to purify the gas.

[0034] Preferably, corresponding to one main pipe: there are two branch pipes.

[0035] By adopting the above technical solution, the two branch pipes corresponding to each main pipe simultaneously deliver gas to the purification cylinder, optimizing the gas delivery method, improving the efficiency of gas entering the purification cylinder, and thus improving the overall working efficiency of the gas purification spray tower.

[0036] In summary, this application includes at least one of the following beneficial technical effects:

[0037] 1. The horizontal distribution of multiple purification cylinders replaces the multi-layer design, reducing the dependence on the height and volume of the spray tower and lowering construction costs such as site, materials and equipment installation;

[0038] 2. The simplified structure reduces operating energy consumption and maintenance difficulty;

[0039] 3. It reduces the requirements for site space and can be applied to places with limited site space. Attached Figure Description
