DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Embodiment: A waste gas treatment device for chemical production, such as Figure 1-Figure 5As shown, it includes a base 1, a smoke exhaust pipe 101, a mounting tube 2, a water tube 22, a visual bin 3, a placing rack 4, a packing layer assembly, a pull rope 13 and a spray assembly. The top of the base 1 is fixedly connected to the water tube 22, the outer wall of the water tube 22 is connected to an air inlet 21, the outer wall of the water tube 22 is provided with a drain outlet, the top of the water tube 22 is connected to three layers of mounting tubes 2, the top of the top mounting tube 2 is fixedly connected to the smoke exhaust pipe 101, the outer wall of the mounting tube 2 is detachably connected to the visual bin 3, the middle part of the visual bin 3 is transparent glass, the outer wall of the mounting tube 2 is fixedly connected to the placing rack 4, one side of the placing rack 4 extends toward the side away from the mounting tube 2, the inside of the mounting tube 2 is connected to the packing layer assembly, the pull rope 13 and the spray assembly, and the pull rope 13 is connected to the packing layer assembly.

[0020] like Figure 2 , Figure 4 and Figure 5 As shown, the packing layer assembly includes a mounting frame 5, a packing layer grid 6 and a guide frame 11. The mounting frame 5 is slidably connected to the bottom of the mounting tube 2, the packing layer grid 6 is detachably connected to the middle of the mounting frame 5, and three guide frames 11 are evenly distributed and fixedly connected to the bottom of the mounting tube 2 along the circumferential direction. The mounting frame 5 and the guide frame 11 are slidably connected via rollers 12.

[0021] like Figure 2 and Figure 4 As shown, the spray assembly includes a spray pipe 9 and a nozzle 10. The outer wall of the installation tube 2 is fixedly connected with the spray pipe 9, the spray pipe 9 is connected to the water supply system, the spray pipe 9 extends into the interior of the installation tube 2, the spray pipe 9 is located above the packing layer grid 6, and the spray pipe 9 is fixedly connected with the nozzle 10.

[0022] When treating chemical waste gas, the chemical waste gas enters the water cylinder 22 through the air inlet 21, and the external water supply system inputs water into the spray pipe 9, and then the inside of the installation cylinder 2 is sprayed with water through the spray pipe 9, thereby reducing the temperature of the waste gas, so that some solid particles in the waste gas are combined with water to form larger water droplets, and then adsorbed and filtered through the packing layer grid 6, and the sewage seeping from the packing layer grid 6 falls into the water cylinder 22, and the waste gas after multi-layer filtration is discharged from the smoke exhaust pipe 101, completing the filtration treatment of the waste gas, and observing the packing layer grid 6 through the visual bin 3. When the packing layer grid 6 is scaled and needs to be cleaned, the air inlet 21 is closed, and the visual bin 3 is opened to allow the installation cylinder 2 to be cleaned. The interior is exposed, and the pull rope 13 is pulled to make the installation frame 5 move upward along the guide frame 11 through the roller 12, so that the packing layer grid frame 6 is close to the visible bin 3, and then the packing layer grid frame 6 is cleaned. When the packing layer grid frame 6 needs to be replaced, the packing layer grid frame 6 is removed and replaced. After cleaning and replacement, the installation frame 5 is reset, and the visible bin 3 is reinstalled on the installation cylinder 2, and then the drain port is opened to discharge the sewage in the water cylinder 22. In this way, the maintenance of the exhaust gas treatment device is completed. During maintenance, the maintenance tools can be temporarily placed on the placement rack 4, which is convenient for workers to maintain the exhaust gas treatment device. The operation is simple and convenient to ensure the purification effect of the exhaust gas treatment device.

The upper and lower fixing frames 7 are fixedly connected inside the top mounting tube 2, and the demister 8 is fixedly connected between the upper and lower fixing frames 7. When the exhaust gas is mixed with water, the moist exhaust gas is discharged from the exhaust pipe 101. The demister 8 can separate the water from the exhaust gas, reduce the water content in the exhaust gas, and avoid the condensation of the moist exhaust gas with the water. The exhaust gas may enter the ground or underground water source with the water flow, causing water pollution, and can also prevent the moist exhaust gas from corroding the exhaust gas treatment device.

[0024] like Figure 4 As shown, it also includes an upper inclined plate 14 and a lower inclined plate 15. Twenty upper inclined plates 14 are fixedly connected to the top of the installation cylinder 2 along the circumferential direction. The end of the upper inclined plate 14 away from the installation cylinder 2 is lower than the end close to the installation cylinder 2. Twenty lower inclined plates 15 are connected to the bottom of the upper inclined plate 14. The upper inclined plates 14 and the lower inclined plates 15 are symmetrically arranged up and down. The upper inclined plates 14 and the lower inclined plates 15 can slow down the flow speed of the exhaust gas and prolong the time that the exhaust gas stays in the installation cylinder 2, thereby improving the filtering efficiency of the exhaust gas.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
