Description

Technical Field

[0001] This utility model belongs to the field of gas purification technology, and in particular relates to a temperature-controlled gas adsorption tank. Background Technology

[0002] In industrial production, inert gases (such as nitrogen and argon) are often used as protective gases to isolate the reaction system from air, while hydrogen is widely used as a reactant or reducing agent in catalytic and synthetic reactions. However, if inert gases or hydrogen contain trace impurities (such as moisture, oxygen, carbon dioxide, hydrocarbons, etc.), they may react with the reactants, leading to decreased product purity, reduced reaction efficiency, and even safety hazards. Therefore, it is necessary to purify inert gases or hydrogen. During the purification process, some reactions require a low-temperature environment to suppress side reactions (heat may be generated when removing oxygen and oxides, requiring timely cooling). At the same time, when the reactants are saturated with impurities, they also need to be cleaned. During the cleaning process, the reactants need to be heated. Existing reaction devices have slow cooling rates and poor temperature uniformity, making rapid heating and cooling inconvenient and hindering efficiency improvement. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a temperature-controlled gas adsorption tank.

[0004] The technical solution adopted by this utility model is as follows: a temperature-controlled gas adsorption tank includes a reaction tank body, the reaction tank is filled with packing material for reaction, a cooling coil is also installed in the reaction tank, the cooling coil is disposed between the packing material, a channel is provided on the inner side wall of the reaction tank, the channel is connected to the cooling coil, a discharge pipe B is installed in the reaction tank, the lower end of the discharge pipe B is located at the lower end of the reaction tank, and the upper end of the discharge pipe B penetrates the upper wall of the reaction tank and is located outside the reaction tank.

[0005] The reaction vessel is equipped with an inlet pipe A at the upper end of its side wall. The inert gas or hydrogen that needs to be purified enters through the inlet pipe A, and after being purified by the reaction packing, it moves to the bottom of the reaction vessel and is discharged through the outlet pipe B at the bottom.

[0006] The reaction vessel is also equipped with an inlet pipe C and an outlet pipe D on its side wall, both of which are connected to the inner side wall channel of the reaction vessel.

[0007] The reaction vessel is equipped with a heating tank at its upper end, and the discharge pipe B passes through the heating tank and is located outside the heating tank.

[0008] The air inlet pipe C and the air outlet pipe D are both equipped with diaphragm valves, and the air inlet pipe A and the discharge pipe B are both equipped with valves.

[0009] The reaction vessel has a material discharge port installed on its bottom wall, and a valve is installed on the material discharge port. The material discharge port is connected to a channel inside the side wall of the reaction vessel for discharging impurities.

[0010] The beneficial effects of this utility model after adopting the above structure are as follows:

[0011] The reaction vessel can freely switch between heating and cooling functions to meet the process requirements of heating and cooling. The entire reaction vessel achieves temperature control through the upper heater and the middle cooling coil. The double-layer container in the middle achieves the effect of heat preservation and water (air) bath.

[0012] When gas enters the reaction tank through the inlet pipe A and flows out through the outlet pipe B, a large amount of reaction heat is generated. At this time, cooling gas enters through the inlet pipe C and flows out through the outlet pipe D, carrying away a large amount of reaction heat, which can quickly achieve the technical effect of uniform cooling.

[0013] When gas enters the reaction tank through the discharge pipe B and flows out through the inlet pipe A, the reaction tank needs to be heated to break down the adsorbed impurities inside. When the upper heating tank is working, the gas entering through the discharge pipe B is heated, flows through the reaction tank, and finally flows out through the inlet pipe A. At this time, the valves of the inlet pipe C and the outlet pipe D are closed, so as not to take away the heat. The reaction tank is kept warm as a whole, which improves the cleaning effect.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0019] like Figure 1 As shown, a temperature-controlled gas adsorption tank includes a reaction tank body 1, which is filled with packing material for the reaction. A cooling coil 2 is also installed inside the reaction tank and is located between the packing material. A channel 3 is provided on the inner side wall of the reaction tank and is connected to the cooling coil 2. A discharge pipe B4 is installed inside the reaction tank. The lower end of the discharge pipe B4 is located at the lower end of the reaction tank, and the upper end of the discharge pipe B4 passes through the upper wall of the reaction tank and is located outside the reaction tank.

[0020] An inlet pipe A5 is installed on the upper side wall of the reaction vessel. The inert gas or hydrogen that needs to be purified enters through the inlet pipe A5, and after being purified by the reaction packing, it moves to the bottom of the reaction vessel and is discharged through the outlet pipe B4 at the bottom.

[0021] The side wall of the reaction vessel is also equipped with an inlet pipe C6 and an outlet pipe D7, both of which are connected to the channel 3 on the inner side wall of the reaction vessel.

[0022] It should be noted that when inert gas or hydrogen enters the reaction vessel to carry out the reaction, cooling water or cooling gas enters the channel 3 of the reaction vessel through the inlet pipe C6, and then enters the cooling coil 2 inside the reaction vessel through the channel 3, and finally exits through the outlet pipe D7. In this process, the cooling water or cooling gas absorbs the heat inside the reaction vessel, thereby achieving the cooling effect of the reaction process.

[0023] A heating tank 8 is installed at the upper end of the reaction tank, and the discharge pipe B4 passes through the heating tank 8 and is located outside the heating tank 8.

[0024] It should be noted that when the impurities adsorbed in the reaction tank need to be decomposed, the reaction tank needs to be heated. The upper heating tank 8 is working. The clean gas enters through the discharge pipe B4, is heated, rises through the packing, flows through the reaction tank, and finally flows out through the inlet pipe A5. At this time, the valves of the inlet pipe C6 and the outlet pipe D7 are closed, so as not to take away the heat, and the reaction tank is kept warm as a whole.

[0025] Both the air inlet pipe C6 and the air outlet pipe D7 are equipped with diaphragm valves 10, and both the air inlet pipe A5 and the discharge pipe B4 are equipped with valves.

[0026] The bottom wall of the reaction vessel is equipped with a material discharge port 9, which is fitted with a valve. The material discharge port 9 is connected to the channel 3 inside the side wall of the reaction vessel for discharging impurities.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents. In conclusion, if those skilled in the art, inspired by this description, design similar structural methods and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
