Description

Technical Field

[0001] The utility model belongs to the technical field of oil and gas adsorption, in particular to a vertical detachable adsorption tank. Background Art

[0002] Petroleum and its products are mixed products of various hydrocarbons, among which the light components are highly volatile. These volatile organic compounds participate in the formation of ozone and secondary aerosols in the atmospheric environment, which has a significant impact on regional atmospheric ozone pollution and PM2.5 pollution. Therefore, volatile organic compounds (VOCs) need to be recovered. Common recovery methods include adsorption treatment, condensation treatment, and absorption treatment. Among them, adsorption treatment is widely used due to its strong adaptability, low cost, and simple process. However, the adsorption equipment that currently uses adsorption to adsorb volatile organic compounds has the disadvantages of being difficult to dissipate the adsorption heat, resulting in significant adsorption heat and heat accumulation, which affects the adsorption rate and adsorption effect. Utility Model Content

[0003] In view of this, in order to solve the above technical problems, the utility model proposes a vertical detachable adsorption tank with a simple structure, which can remove the adsorption heat in time, effectively improve the adsorption rate, and optimize the adsorption effect.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0005] A vertical detachable adsorption tank, comprising:

[0006] The tank body comprises a cylinder, a detachable top cover on the top of the cylinder and a bottom cover; an air inlet pipe is provided at the lower end of the side wall of the cylinder; an air outlet pipe, an exhaust pipe, a coolant pipe inlet and a coolant pipe outlet are provided on the top cover; and a sewage pipe is provided on the bottom cover;

[0007] The lower buffer filter layer is circular and is located at the lower end of the inner cavity of the cylinder and above the air inlet pipe.

[0008] An upper buffer filter layer, which is annular and disposed at the upper end of the inner cavity of the cylinder;

[0009] A support seat, the support seat comprising an outer ring fixed to the inner wall of the cylinder and located below the upper buffer filter layer, an inner cylinder concentrically arranged with the outer ring, and a connecting rod connecting and fixing the inner cylinder to the outer ring; the inner diameter of the inner cylinder is consistent with the inner diameter of the inner circle of the upper buffer filter layer;

[0010] A cooler, the cooler being arranged in the inner cylinder; the coolant inlet of the cooler being connected to a coolant inlet pipe, the coolant inlet pipe passing through the coolant pipe inlet being connected to an external coolant supply end; the coolant outlet of the cooler being connected to a coolant outlet pipe, the coolant outlet pipe passing through the coolant pipe outlet being connected to an external coolant recovery end;

[0011] The adsorption medium is filled in the inner cavity of the cylinder and is located between the lower buffer filter layer and the upper buffer filter layer.

[0012] The oil and gas enter the tank through the air inlet pipe, pass through the lower buffer filter layer and then enter the adsorption medium, where they are adsorbed. The gas after adsorption purification passes through the upper buffer filter layer and then is discharged through the air outlet pipe. The heat generated during the adsorption process is removed through heat exchange cooling in the cooler. The coolant enters the cooler through the coolant inlet pipe, exchanges heat with the adsorption medium, removes the heat generated in the adsorption medium, and heats up the coolant. The heated coolant is then discharged through the coolant outlet pipe. The cooler is set in the middle of the adsorption medium where the adsorption heat is most concentrated, so that the generated heat can be removed in time to avoid heat accumulation. Open the top cover, remove the coolant inlet pipe and the coolant outlet pipe, and then take the cooler out of the tank for easy maintenance later.

[0013] Furthermore, the side wall of the cylinder is provided with an adsorption medium feeding port, an adsorption medium discharging port and a manhole to facilitate the replacement of the adsorption medium.

[0014] Furthermore, a dividing net is provided in the middle of the inner cavity of the cylinder to divide the inner cavity into an upper adsorption area and a lower adsorption area, and the upper adsorption area and the lower adsorption area are both filled with the adsorption medium; the side walls of the cylinder corresponding to the upper adsorption area and the lower adsorption area are provided with the adsorption medium feeding port, the adsorption medium unloading port and the manhole.

[0015] The use of a splitting net to divide the adsorption medium into two layers can relieve the pressure on the bottom adsorption medium and prevent the bottom adsorption medium from being crushed by an overly high adsorption medium layer.

[0016] Furthermore, the lower buffer filter layer has a three-layer structure, which includes a lower grid plate, a lower buffer layer and a lower filter layer from bottom to top.

[0017] Furthermore, the upper buffer filter layer is a three-layer structure, which includes an upper filter layer, an upper buffer layer and an upper grid plate from bottom to top.

[0018] Furthermore, the adsorption medium is activated carbon; and the cooling liquid in the cooler is circulating cold water or ethylene glycol.

[0019] Compared with the prior art, the vertical detachable adsorption tank described in the utility model has the following advantages:

[0020] The vertical detachable adsorption tank described in the utility model has a simple structure. On the basis of the traditional adsorption tank, by arranging the cooler in the middle position of the adsorption medium where heat is most easily accumulated and the heat is most difficult to remove, the generated adsorption heat can be removed in time, avoiding the situation where heat accumulation affects the adsorption rate and adsorption effect; the top cover, bottom cover and cylinder are detachably connected in a structure that is convenient for maintenance inside the tank and for inspection and maintenance of the cooler.
