Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of waste gas and wastewater treatment, in particular to a particle adsorbent desorption tank. Background Art
[0002] Granular adsorbents are often used to adsorb impurities and harmful components in gases or liquids due to their porous structure and large specific surface area. When a granular adsorbent adsorbs a certain amount of pollutants, its adsorption capacity will decrease. At this time, the granular adsorbent needs to be regenerated to restore its adsorption capacity. The desorption regeneration tank is the equipment to complete this process.
[0003] At present, more and more industrial enterprises are using particle adsorbent adsorption equipment to adsorb and treat impurities and organic components generated by production lines. Some enterprises do not have desorption and regeneration equipment, and the particle adsorbents after adsorption saturation can only be treated as hazardous waste. It costs a lot of money to hire people to recycle them at a high price and purchase new particle adsorbents to fill the equipment. Some enterprises have multiple particle adsorbent waste gas treatment equipment. If all of them are equipped with in-situ desorption and regeneration devices, the cost is too high to bear. Therefore, there is an urgent need for a desorption and regeneration device to solve the problem of high environmental protection management costs in the form of centralized desorption and regeneration. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, the utility model aims to provide a desorption regeneration device in the form of a particle adsorbent desorption tank, which performs centralized desorption regeneration. The particle adsorbent after desorption and regeneration can be reloaded into the adsorption equipment for continued use, and has a good adsorption effect. This process only consumes a small amount of electricity or natural gas, which can save environmental protection management costs for enterprises.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A particulate adsorbent desorption tank comprises a tank body, a feed port cover, an air inlet, an air outlet, a first pneumatic valve, a second pneumatic valve and a temperature sensor, wherein the feed port cover is movably connected to the top of the tank body, the air outlet is fixedly connected to the side of the tank body and close to the feed port cover, the temperature sensor is connected to the side of the tank body and close to the air outlet, the air inlet is arranged at the bottom of the tank body, the first pneumatic valve and the second pneumatic valve are both fixedly connected to the bottom of the tank body, the first pneumatic valve is fixedly connected to the top of the air inlet, the second pneumatic valve is fixedly connected to the bottom of the air inlet, and a discharge port is also arranged at the bottom of the tank body.
[0007] Compared with the prior art, the particle adsorbent desorption tank of the present application has the following beneficial effects:
[0008] In actual application, the granular adsorbent particles are evenly added into the interior of the tank body, and the hot air flow enters the tank body through the air inlet at the bottom. The air flow temperature is monitored by the temperature sensor to keep it stable. The hot air flow passes through the first pneumatic valve to gradually heat the granular adsorbent particles, and then is discharged through the air outlet. A small hole is opened on the first pneumatic valve baffle at the top of the air inlet to facilitate the hot air flow to flow out of the air inlet. The second pneumatic valve at the bottom of the air inlet plays a sealing role. When the regeneration tank is desorbed, the two sets of pneumatic valves are opened to discharge the material through the discharge port at the bottom of the tank body.
[0009] Preferably, a movable grille and a guide plate are further provided, the guide plate and the movable grille are both fixedly connected to the inside of the tank body, and the movable grille is provided above the guide plate.
[0010] Beneficial effect: The movable grid inside the tank body is arranged to facilitate the granular adsorbent particles to fall evenly into the lowered guide plate for accumulation when falling. The guide plate divides the inside of the tank body into independent sectors, which helps the adsorbent particles to fall and desorb and conduct heat more evenly.
[0011] Preferably, the tank body is cylindrical, a heat-insulating layer is provided on the outer side of the tank body, and an inspection port is provided on the bottom of the tank body.
[0012] Beneficial effect: By setting an insulation layer on the outside of the tank body, the temperature inside the tank body is kept constant, which is conducive to the desorption of the granular adsorbent particles. An inspection port is opened at the bottom of the tank body to observe the situation inside the tank. When the pneumatic valve fails and cannot unload, the inspection port can be opened as a temporary drain to discharge the adsorbent particles in the equipment.
[0013] Preferably, the feed port cover is flipably connected to the top of the tank body, and a stop edge is provided on the top of the tank body.
[0014] Beneficial effects: By setting a stopper edge on the top of the tank, when the staff adds adsorbent granules, the spilled adsorbent granules are not easy to fall out of the tank. There are several drainage holes on the stopper edge to prevent water from accumulating on the top when the equipment is placed outdoors. The flip-up connection of the feed port cover is convenient for the staff to open and add materials.
[0015] Preferably, an equipment bracket is further provided, and the equipment bracket is fixedly connected to the tank body.
[0016] Beneficial effect: The regeneration tank is supported by the equipment bracket to make its bottom connection stable and firm.
[0017] Preferably, a ladder and an operating platform are also fixedly connected to the equipment bracket.
[0018] Beneficial effect: By setting up a ladder and an operating platform, the operator can use the ladder to go up and down the operating platform to desorb the regeneration tank.
[0019] Preferably, a hoist is also provided, the hoist is fixedly connected to the operating platform, and the hoist is arranged above the feed port cover.
[0020] Beneficial effect: By connecting a hoist to the operating platform, the operator can save effort by using the hoist to move the granular adsorbent bag to the top of the feed port cover of the regeneration tank. BRIEF DESCRIPTION OF THE DRAWINGS

The temperature sensor 3 arranged on the tank body 1 monitors the desorption temperature in real time. The whole process is continuously carried out to achieve the desorption effect. The first pneumatic valve 6 and the second pneumatic valve 9 are arranged at the bottom of the tank body 1. The first pneumatic valve 6 is provided with uniform small holes to prevent the particulate adsorbent pellets from falling, and at the same time, the hot air flow can pass through uniformly upward.
