Description

Technical Field

[0001] The utility model relates to the technical field of packed towers, in particular to a composite chemical packed tower. Background Art

[0002] The composite chemical packed tower is a chemical equipment that integrates a packed tower with other technical elements. It is mainly composed of a tower body, a packing layer, a liquid distribution device, a gas distribution device, a redistribution device, a defoaming device and other parts. The tower body is filled with packings of various shapes and materials to provide a surface for gas-liquid contact and promote mass transfer and heat transfer processes. The working principle of the composite chemical packed tower is based on the large surface area provided by the packing layer, which enables effective contact between gas and liquid, thereby realizing separation, adsorption, reaction and other process processes. The liquid is sprayed onto the packing from the top of the tower through the liquid distributor and flows down along the surface of the packing; the gas is fed into the tower from the bottom, and after being distributed by the gas distribution device, it flows through the gaps in the packing layer in countercurrent or cocurrent with the liquid. On the surface of the packing, the gas and liquid phases are in close contact for mass transfer and heat transfer to achieve the process goals;

[0003] The packing in the existing chemical packing tower usually needs to be sprayed with liquid. Since the liquid may contain impurities, it is easy to cause the internal holes to become clogged, which not only slows down the operation efficiency of the packing tower, but also affects the work efficiency. To solve this problem, in the patent document with publication number CN 218358352 U, a motor drives a threaded rod to rotate, the threaded rod drives a slider to move, the slider drives a connecting rod to move, and the connecting rod drives a cleaning brush to move to clean the filter plate, clean the impurities to a place near the second manhole, and then use a long rod to pull a scraper to discharge the impurities accumulated after cleaning through the second manhole, thereby avoiding the problem of clogging of the holes inside the packing tower, improving the operation efficiency and improving the anti-clogging performance. However, after the filter plate is cleaned by the cleaning brush driven by the connecting rod, it is still necessary to manually use a long rod to pull the scraper to discharge the impurities accumulated after cleaning through the second manhole, resulting in the need for special staff to handle it. When the long rod is manually operated, it is easy to cause the dirt on the outside of the scraper to be pushed out of the position away from the second manhole, and the problem of cleaning the filter plate is not fundamentally solved.

[0004] In order to solve the above problems, it is necessary to improve the filter screen plate and the cleaning assembly based on the structure of publication number CN 218358352 U to solve the above technical problems.

[0005] Therefore, it is necessary to provide a new composite chemical packing tower to solve the above technical problems. Utility Model Content

[0008] The cleaning assembly includes a rotating shaft, which is rotatably mounted on the top of the truncated cone-shaped filter plate, and a plurality of cleaning plates distributed in an annular manner are provided on the rotating shaft;

[0009] The sewage discharge assembly includes a sewage collecting cylinder, a sewage inlet is provided on the sewage collecting cylinder, and a spiral plate for spiral discharge is provided in the sewage collecting cylinder.

[0010] Preferably, a fixing ring is fixedly installed on the outer ring wall of the bottom of the truncated cone filter screen plate, and the fixing ring is fixedly installed in the packing tower. A plurality of mounting holes are opened on the fixing ring, and a sewage discharge component is provided at each mounting hole.

[0011] Preferably, the dirt collecting cylinder is fixedly engaged in the mounting hole provided in the fixing ring, and the lower wall of the dirt inlet provided in the dirt collecting cylinder is flush with the upper surface of the fixing ring.

[0012] Preferably, a rotatably connected rotating column is fixedly installed in the dirt collecting barrel, and a servo motor for driving the rotating column to rotate is mounted at the bottom of the dirt collecting barrel, and the spiral plate is fixedly sleeved on the rotating column.

[0013] Preferably, a sewage discharge pipe connected to the sewage collecting cylinder is fixedly installed on the outer ring wall near the top of the sewage collecting cylinder, and the sewage discharge pipe extends out of the packing tower.

[0014] Preferably, a driving motor for driving the rotating shaft to rotate is fixedly mounted on the inner plate wall of the frustum-shaped filter screen plate.

[0015] Preferably, the frustum-shaped filter screen is provided with a protective cover for covering the drive motor and the servo motor.

[0016] Compared with related technologies, the composite chemical packing tower provided by the present invention has the following beneficial effects:

[0017] The utility model starts the driving motor to drive the cleaning plate on the rotating shaft to brush the conical filter screen plate, so the conical filter screen plate can be cleaned quickly, and the hidden danger of clogging of the conical filter screen plate is effectively prevented. Since the conical filter screen plate is narrow at the top and wide at the bottom, the dirt brushed off can flow along the inclined surface of the cone to the fixed ring. When the dirt is discharged onto the fixed ring, it can flow to the sewage inlet opened in the sewage collecting barrel with the flushing of water. At this time, the servo motor is turned on to drive the spiral plate to rotate, so that the spiral plate can transport the dirt and impurities upward along the sewage collecting barrel, and the dirt and impurities are then discharged to the outside through the sewage pipe, so that the cleaned dirt does not need to be handled manually, saving time and effort.
