[0002] Printing plates are the materials needed for printing. A lot of industrial waste gas will be generated during the production process of printing plates. If this kind of waste gas is discharged into the atmosphere without being treated to meet the standards, it will inevitably reduce the quality of the atmospheric environment and cause serious harm to human health. Therefore, waste gas treatment equipment is needed in the production process of printing plates to treat the waste gas generated during the production process of printing plates.

[0003] For example, Chinese patent application No. 202021830262.8 is a waste gas treatment device for printing plate production.

At the same time, it absorbs part of the waste gas and reduces the concentration of combustibles in the waste gas.

[0004] It has the following defects:

[0005] The tiny water droplets have less absorption and filtering effect on particles, impurities, and some water-soluble harmful gases in the exhaust gas, which can lead to higher concentrations of particles, impurities, and some water-soluble harmful gases in the exhaust gas after filtration. Therefore, the exhaust gas treated with tiny water droplets will be discharged into the air, which can still cause a high degree of air pollution.

First, add a certain amount of clean water into the water tank 6, and then start the water pump 7. The start of the water pump 7 will transport the clean water in the water tank 6 to the exhaust gas treatment box 1 through the connecting pipe 8, until the water in the exhaust gas treatment box 1 overflows the leak plate 5, and then transport the waste gas produced by the printing plate to the first air inlet pipe 3, and then start the air intake pump 2. The start of the air intake pump 2 will transport the waste gas transported to the first air intake pipe 3 through the second air intake pipe 4 to the clean water at the bottom inner side of the exhaust gas treatment box 1. The waste gas transported to the clean water at the bottom inner side of the exhaust gas treatment box 1 will absorb and filter the particles, impurities, and some water-soluble harmful gases in the waste water under the action of the clean water, and the impurities and particles filtered by the clean water will settle below the leak plate 5. The cooperation between the water storage tank 6 and the water pump 7 facilitates the injection of water into the exhaust gas treatment box 1. The setting of the air intake pump 2 facilitates the absorption and filtration of particles, impurities, and some harmful gases that are easily soluble in water in the exhaust gas transported to the exhaust gas treatment box 1, thereby reducing the pollution caused by the exhaust gas discharged into the air.

[0023] A connection frame 11 is fixedly connected in the waste gas treatment box 1. The connection frame 11 is located above the leak plate 5. A heating resistor 12 is fixedly connected in the connection frame 11. A plurality of heating resistors 12 are arranged in sequence. When the waste gas filtered by clean water passes through the connection frame 11, the heating resistor 12 is started. The start of the heating resistor 12 will dry and evaporate the water in the waste gas, thereby avoiding the problem that the humidity of the filtered waste gas is too high and affects the working environment of the printing plate production device.

[0024] like Figure 4 As shown, a filter plate 13 is provided in the waste gas treatment box 1. The filter plate 13 is located above the connection frame 11.

[0026] The working principle of the utility model is:

[0027] First, add a certain amount of clean water into the water storage tank 6, and then start the water pump 7. The start of the water pump 7 will transport the clean water in the water storage tank 6 to the exhaust gas treatment box 1 through the connecting pipe 8, until the water in the exhaust gas treatment box 1 overflows the leak plate 5, and then transport the waste gas produced by the printing plate to the first air intake pipe 3, and then start the air intake pump 2. The start of the air intake pump 2 will transport the waste gas transported to the first air intake pipe 3 through the second air intake pipe 4 to the clean water at the bottom end of the inner side of the exhaust gas treatment box 1. The waste gas transported to the clean water at the bottom end of the inner side of the exhaust gas treatment box 1 will absorb the particles, impurities, and some harmful gases that are easily soluble in water in the waste water under the action of the clean water. The impurities and particles filtered by the clean water will settle under the leak plate 5. When the exhaust gas filtered by the clean water floats upward through the connecting frame 11, the heating resistor 12 is started. The activation of the heating resistor 12 will dry and evaporate the moisture in the exhaust gas. When the exhaust gas with dried moisture floats upward through the filter plate 13, the filter mesh layer 131 will filter the impurities or dust in the exhaust gas again. The filtered exhaust gas will pass through the activated carbon layer 132 and the anti-biochemical activated carbon cloth layer 133 to absorb and filter the harmful gas. In this way, the exhaust gas can be further treated, thereby making the treatment of the exhaust gas cleaner and reducing the pollution of the exhaust gas to the air.
