Description

Technical Field

[0001] This utility model relates to the field of mixing tank technology, specifically to a desorption gas mixing tank. Background Technology

[0002] Pressure swing adsorption (PSA) technology utilizes the differences in the equilibrium adsorption capacity, adsorption rate, and other adsorption characteristics of different gas components on an adsorbent, as well as the characteristic that the adsorption capacity changes with pressure. By periodically changing the pressure, the adsorption and desorption processes are alternated, thereby achieving the separation or purification of gases.

[0003] In the pressure swing adsorption (PSA) cycle, the mixed feed gas enters the adsorption bed from the bottom of the adsorption tower for adsorption. The adsorbent in the PSA unit can be desorbed by low-pressure flushing and vacuum desorption. During the desorption process, various desorbed gases need to enter the desorbed gas mixing tank for mixing and buffering before being sent out of the PSA unit. However, the existing desorbed gas mixing tanks have poor mixing and buffering effects when mixing and buffering the desorbed gases. They cannot accurately control the gas pressure inside the tank during use. Excessive pressure may cause the gas to be discharged before it is fully mixed, resulting in poor practicality. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a desorbed gas mixing tank that can ensure that the desorbed gas entering the mixing tank can be fully and evenly mixed.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.

[0006] A desorption gas mixing container includes a container body with support legs at the bottom. The lower part of the container body is provided with a first air inlet pipe and a second air inlet pipe communicating with the inner cavity of the container. An air outlet pipe is provided inside the container body along its axial direction, with its top penetrating the top cover of the container body. An air inlet hole is opened on the lower periphery of the air outlet pipe. An opening and closing assembly for controlling the opening and closing of the air inlet hole is installed at the bottom of the container body. A flow guide tube is also provided inside the container body, and the flow guide tube is sleeved outside the air outlet pipe.

[0007] In the aforementioned desorption gas mixing container, the air intake directions of the first air intake pipe and the second air intake pipe are respectively tangent to the side wall of the container body, and the air intake direction of the first air intake pipe is opposite to that of the second air intake pipe.

[0008] In the aforementioned desorption gas mixing container, the air inlet holes are evenly arranged along the axial and circumferential directions of the air outlet pipe.

[0009] The aforementioned desorption gas mixing can includes an opening and closing assembly comprising a sealing plug that is slidably connected to the bottom of the outlet pipe and blocks the inlet hole. An extension cylinder that is slidably connected to the sealing plug is provided at the bottom of the can body. A guide post is provided on the bottom surface inside the extension cylinder. A moving groove that is slidably connected to the guide post is provided at the bottom of the sealing plug. A return spring is sleeved on the outside of the guide post. One end of the return spring is connected to the extension cylinder, and the other end is connected to the bottom surface of the sealing plug.

[0010] The aforementioned desorption gas mixing tank is further provided with baffles on the inner side wall of the tank, and the baffles are arranged at intervals along the axial direction of the tank.

[0011] The technological advancements achieved by this utility model are as follows, due to the adoption of the above technical solutions.

[0012] This invention provides a desorbed gas mixing tank. By setting a guide tube to guide the desorbed gas and using a baffle to agitate the airflow, the airflow path is extended, allowing sufficient mixing time for the desorbed gas to achieve uniform mixing. Furthermore, the desorbed gas delivered into the tank through the first and second air inlets directly forms a swirling flow, enabling better mixing. At the same time, by setting an opening and closing component that changes with the tank pressure, the discharge of the desorbed gas is controlled to ensure that the desorbed gas is fully mixed and to prevent the direct discharge of unevenly mixed desorbed gas due to excessive pressure, thus ensuring the mixing effect of the desorbed gas.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] A desorption gas mixing container, such as Figures 1 to 2 As shown, the device includes a tank body 1, with a support leg 13 at the bottom. The lower part of the tank body 1 is provided with a first air inlet pipe 2 and a second air inlet pipe 3 that communicate with the inner cavity of the tank body 1. An air outlet pipe 4 is provided inside the tank body 1 along the axial direction of the tank body 1. The top of the air outlet pipe 4 passes through the top cover of the tank body 1. An air inlet hole 7 is opened on the lower periphery of the air outlet pipe 4. An opening and closing assembly for controlling the opening and closing of the air inlet hole 7 is installed at the bottom of the tank body 1.

[0018] The air intake directions of the first air intake pipe 2 and the second air intake pipe 3 are tangent to the side wall of the tank body 1, and the air intake direction of the first air intake pipe 2 is opposite to that of the second air intake pipe 3, which facilitates better mixing after the formation of swirl.

[0019] Inside the tank body 1, there is also a guide tube 5, which is set outside the gas outlet pipe 4 to guide the desorbed gas and promote the mixing of the desorbed gas.

[0020] A baffle plate 6 is also provided on the inner wall of the tank body 1. The baffle plate 6 is arranged at intervals along the axial direction of the tank body 1, which can promote uniform mixing of desorbed gas.

[0021] The air inlets 7 are evenly arranged along the axial and circumferential directions of the air outlet pipe 4, which facilitates the control of the gas flow rate entering the air outlet pipe.

[0022] The opening and closing assembly includes a sealing plug 8 that is slidably connected to the lower part of the air outlet pipe 4 and seals the air inlet 7. An extension cylinder 12 that is slidably connected to the sealing plug 8 is provided at the bottom of the tank body 1. A guide post 9 is provided on the bottom surface inside the extension cylinder 12. A return spring 10 is sleeved on the outside of the guide post 9. One end of the return spring 10 is connected to the extension cylinder 12, and the other end is connected to the bottom surface of the sealing plug 8. A moving groove 11 that is slidably connected to the guide post 9 is provided at the bottom of the sealing plug 8.

[0023] The guide posts 9 are evenly distributed in a circular pattern, and in this embodiment, there are six guide posts 9.

[0024] The air inlet 7 at the bottom of the air outlet pipe 4 is blocked by the sealing plug 8. When the pressure inside the mixing tank reaches a certain value, the sealing plug is pushed down to open the air inlet 7, so that the desorbed gas after mixing is directly discharged from the air outlet pipe. When the pressure value decreases, the sealing plug is gradually reset under the action of the return spring to block the air inlet.

[0025] This invention provides a desorbed gas mixing tank. By setting a guide tube to guide the desorbed gas and using a baffle to agitate the airflow, the airflow path is extended, allowing sufficient mixing time for the desorbed gas to achieve uniform mixing. Furthermore, the desorbed gas delivered into the tank through the first and second air inlets directly forms a swirling flow, enabling better mixing. At the same time, by setting an opening and closing component that changes with the tank pressure, the discharge of the desorbed gas is controlled to ensure that the desorbed gas is fully mixed and to prevent the direct discharge of unevenly mixed desorbed gas due to excessive pressure, thus ensuring the mixing effect of the desorbed gas.
