The second tail gas pipeline is connected with the gas inlet end of the second switch valve. The first steam input valve is installed at the gas inlet end of the first tail gas pipeline and close to the first switch valve. And the steam input valve II is vertically mounted at the top of the middle of the liquid collecting tank. The third steam input valve is installed at the gas outlet end of the second tail gas pipeline and close to the second switch valve. The level gage is installed at the one-third position of the bottom of the liquid collecting tank. The vertical end of the discharge valve is installed at the bottom of the discharge valve, and the other end of the discharge valve is connected with the discharge pipe which is connected with the storage box. The storage height of the bottom of the material collecting groove is monitored through the material level indicator, and when the storage height exceeds the design requirement, the discharge valve is opened to discharge materials into the material storage box. When the discharging speed is low, the second steam input valve is opened, and the tail liquid is heated and softened through steam. When the whole tail gas treatment system detects that the resistance of the pipeline is increased, the circulation sectional area of the tail gas pipeline is reduced, a first switch valve and a second switch valve can be controlled to be opened and closed, steam softening tail liquid is input from a first steam input valve and a third steam input valve in a partitioned mode, tail liquid accumulated in the first tail gas pipeline and the second tail gas pipeline is exhausted in an accelerated mode, and the tail liquid is collected in a collecting tank. And the tail gas is collected into the storage box through the discharge valve and the discharge pipe, so that the normal operation of the tail gas treatment system is ensured.

Description

Technical Field

[0001] This utility model relates to the field of chemical production exhaust gas treatment, and in particular to a chemical material exhaust gas anti-clogging treatment device. Background Technology

[0002] Currently, many chemical enterprises generate various types of exhaust gases during production processes due to different technologies. These exhaust gases are treated by exhaust gas purification equipment to meet emission standards. However, over long periods of operation, the exhaust gases can deposit under gravity, forming tail liquid. If this tail liquid is not cleaned for a long time, it will slowly crystallize at the bottom of the pipes. The crystals will accumulate over time until the pipes are completely blocked, rendering the exhaust gas purification equipment inoperable. This disrupts the normal production and operation of the entire chemical enterprise and makes maintenance extremely difficult. Therefore, we have developed a chemical material exhaust gas anti-clogging treatment device. Utility Model Content

[0003] To address the above problems, this utility model overcomes the technical difficulties of cleaning and preventing blockages in chemical plant exhaust gas pipelines, which negatively impact production and operations. It provides a more efficient cleaning and lower maintenance cost anti-blockage treatment device for chemical exhaust gas pipelines.

[0004] This utility model provides a chemical material tail gas anti-clogging treatment device, which includes a first switch valve (1), a first steam input valve (2), a first tail gas pipeline (3), a first tail gas elbow (4), a second steam input valve (5), a second tail gas elbow (6), a second tail gas pipeline (7), a third steam input valve (8), a second switch valve (9), a collection trough (10), a level gauge (11), a discharge valve (12), a discharge pipe (13), and a storage tank (14).

[0005] Further improvements are made in the following ways: exhaust pipe 1 (3) and exhaust pipe 2 (7) are made in sections and not exceed 6 meters in length, and are connected by flanges.

[0006] Further improvements are made in that: the first (1), the second (9), the first (2), the second (5), and the third (8) steam input valves are automatically controlled by electric switching valves.

[0007] Further improvements are made in that: exhaust bend one (4), exhaust bend two (6), and collection trough (10) are all independent components and are connected by flanges.

[0008] Further improvements include: the level gauge (11) adopts a flange connection.

[0009] Further improvements include: the discharge pipe (13) adopts a flanged stainless steel metal hose.

[0010] The beneficial effects of this utility model are as follows:

[0011] This utility model installs a steam heating melting device on the exhaust gas conveying pipeline, and implements anti-clogging cleaning modes such as segmented, zoned, manual and automatic, single-point and multi-point cleaning of the exhaust gas pipeline, which completely solves the technical problems of exhaust gas pipeline blockage and cleaning difficulties in chemical enterprises.

[0012] The U-shaped collection trough (10) and the slope design of tail gas pipe one (3) and tail gas pipe two (7) not only reduce the flow resistance of flue gas during the pipeline transportation process, but also efficiently collect the collected tail liquid, achieving the purpose of secondary recycling and reuse of materials.

[0013] This device has a simple structure and is easy to operate. It implements automated remote control and local control, which greatly saves on manual maintenance costs while ensuring stable system operation. It reduces the drawback of having to shut down production for maintenance due to pipeline blockage, and responds to the national call for energy conservation, emission reduction, cost reduction and efficiency improvement.
