Description

Technical Field

[0001] The utility model relates to the field of tail gas purification, and more specifically, to an adjustable catalyst adding device. Background Art

[0002] Tail gas is produced in the production process of dichlorotoluene. If it is discharged directly without treatment, it will cause serious environmental pollution. Therefore, the tail gas needs to be treated by a tail gas treatment device. During the treatment process, a catalyst needs to be added (liquid catalysts are often used for dichlorotoluene tail gas purification) to speed up the treatment rate.

[0003] At present, catalysts are generally added to exhaust gas treatment devices through catalyst adding equipment. However, when the catalyst is added to the catalyst adding equipment, since the adding equipment is connected to the exhaust gas treatment device, some exhaust gas will leak out from the adding equipment, which may easily cause harm to surrounding personnel. In addition, when the catalyst is added, the adding position is fixed, resulting in a smaller spraying coverage area. Especially when encountering exhaust gas treatment equipment with a larger internal space, it is easy to cause the catalyst to be unable to contact the exhaust gas more comprehensively, thereby affecting the purification efficiency of the exhaust gas.

[0004] Therefore, in order to solve the above technical problems, the present application proposes an adjustable catalyst addition device. Utility Model Content

[0007] Preferably, the movable adjustment component includes a motor A fixed on one side of the exhaust gas treatment device shell, and a reciprocating screw that drives the rod sleeve to move back and forth is installed on the transmission part of the motor A. The surface of the rod sleeve is fixed to the back of the nozzle through a connecting rod, and a track assembly that maintains the linear movement of the rod sleeve is provided at the rear of the rod sleeve. This embodiment is suitable for an exhaust gas treatment device with a square shell.

[0011] Preferably, both sides of the catalyst tank are fixed to the top of the catalyst tank through a support plate, and the two sides of the catalyst tank are supported by the support plate to avoid the vertical pipe from bearing a large force, thereby causing the connection part with the exhaust gas treatment device shell to be deformed due to force.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. When the top cover is opened and the liquid catalyst is added into the catalyst tank, the vertical pipe can be closed by the valve, thereby closing the passage connected to the tail gas treatment device to prevent tail gas from leaking from here, thereby solving the problem in the background technology that when the catalyst is added into the catalyst adding device, part of the tail gas will leak out from the adding device;

[0015] 2. The utility model drives the movement of the nozzle by moving the adjustment component, thereby continuously adjusting the position of the nozzle inside the exhaust gas treatment device shell to expand the spraying range of the catalyst, so that the catalyst can better contact with the exhaust gas to improve the purification efficiency of the exhaust gas, thereby solving the problem of small spraying coverage in the background technology.

After the liquid catalyst is added, the top cover 2 is closed and the top of the catalyst tank 1 is sealed.
