[0002] Multi-pollutant combined cycle removal devices are an integrated and efficient environmental governance technology with advantages of high efficiency, energy saving, environmental protection, and economy, and are becoming the mainstream development direction of modern industrial pollution control. Traditional treatment methods require the construction of separate independent systems for desulfurization, denitrification, and dust removal, which require a large area and high equipment investment. Multi-pollutant combined removal devices, through integrated design, reduce the number of equipment and the area occupied, and lower the initial investment and subsequent maintenance costs. While removing pollutants, the combined removal technology can convert SO2 into useful chemicals such as concentrated sulfuric acid and sulfur, realizing waste resource utilization and reducing secondary pollution.

[0003] However, the multi-pollutant combined circulation removal devices commonly available on the market have some obvious drawbacks: First, the disassembly process of the wastewater collection tank is extremely inconvenient, which not only consumes a lot of time and manpower, but also increases the difficulty and complexity of maintenance work; second, the operating platform of the particle separator lacks dust protection equipment, which will affect the service life of the operating platform in the long run; therefore, it is necessary to design a multi-pollutant combined circulation removal device. Utility Model Content

[0004] The purpose of this invention is to provide a multi-pollutant combined circulation removal device to solve the shortcomings of existing multi-pollutant combined circulation removal devices, such as the difficulty in disassembling the wastewater collection tank and the lack of dust protection equipment on the operating platform.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a multi-pollutant combined circulation removal device, including a supporting base plate, a particle separator, a dustproof plate, an operating platform, a dehumidification device, an operating button, a wastewater collection tank, a catalytic reactor, and a demisting and dust removal device. The particle separator is fixedly connected to the supporting base plate, and the operating platform and a fixing block are fixedly connected to the particle separator. A limiting shaft is sleeved in a through hole opened on the fixing block. A fixing shaft is fixedly connected to the operating platform, and a connecting block is rotatably connected to the fixing shaft. A dustproof plate is fixedly connected to the connecting block, and a limiting block is fixedly connected to the dustproof plate. A fixing plate is fixedly connected to the supporting base plate, and a sliding groove is opened on the fixing plate. A limiting plate is slidably connected in the sliding groove, and one end of a spring is fixedly connected to the limiting plate. The other end of the spring is fixedly connected to the sliding groove.

[0006] As a further technical solution of this utility model, the particle separator is fixedly connected to one end of the first pipe and the second pipe, and the other end of the second pipe is fixedly connected to a dehumidification device, which is equipped with an operation button.

[0007] As a further technical solution of this utility model, a dehumidification device, a first support frame, a second support frame, and a defogging and dust removal device are fixedly connected to the support base plate.

[0008] As a further technical solution of this utility model, one end of the dehumidification equipment is fixedly connected to a third pipe, the other end of the third pipe is fixedly connected to a spray tower, and the spray tower is fixedly connected to a first support frame.

[0009] As a further technical solution of this utility model, one end of the seventh pipe is fixedly connected to the bottom of the spray tower, and the other end of the seventh pipe is fixedly connected to the wastewater collection tank, and the wastewater collection tank is slidably connected in the groove opened in the fixed plate.

[0010] As a further technical solution of this utility model, one end of the fourth pipe is fixedly connected to the spray tower, and the other end of the fourth pipe is fixedly connected to the water storage tank, which is fixedly connected to the support base plate.

[0012] This utility model provides a multi-pollutant combined circulation removal device, the advantages of which are as follows: Waste gas enters a particle separator through a first pipe, where large particles are removed. The waste gas then enters a dehumidification device through a second pipe, where its moisture content is reduced. Finally, it enters a spray tower through a third pipe, where it comes into countercurrent contact with an alkaline / neutral aqueous solution to neutralize the acidic gas. The spray system employs a high-efficiency nozzle design to ensure sufficient gas-liquid contact. The spray-treated waste gas then enters a catalytic reactor through a fifth pipe, where selective catalytic reduction and other technologies are used to remove NO under the action of a catalyst. X The waste gas is reduced to N2 and H2O, while some mercury is oxidized to divalent mercury, which facilitates subsequent removal. The waste gas enters the demister and dust collector through the sixth pipe. The demister and dust collector performs dust removal treatment, specifically targeting ultrafine particles smaller than PM1, ultimately achieving deep purification of the flue gas. The waste liquid in the spray tower enters the wastewater collection tank through the seventh pipe. The limiting plate is pushed into the groove of the fixed plate, and finally the wastewater collection tank is removed. This not only saves a lot of time and manpower, but also reduces the difficulty and complexity of maintenance work. The limiting shaft is removed, and the dustproof plate is rotated around the fixed shaft. The limiting block is then fitted into the fixed block, and the limiting shaft is installed to complete the fixation. The dustproof plate can improve the service life of the operating platform.
