Description

Technical Field

[0001] The utility model relates to the technical field of descaling of heat exchange equipment, in particular to a descaling circulation device for a pressure swing adsorption oxygen generation heat exchange equipment. Background Technique

[0002] After the factory circulating cooling water system operates for a period of time, a large amount of calcium and magnesium carbonate scale and microbial sludge will form in the water. These dirt firmly adhere to the inner surface of the heat exchanger, resulting in deteriorated heat transfer and increased circulating water pressure, affecting the operating efficiency of the unit and causing significant economic losses over time. At present, when descaling the pressure swing adsorption oxygen generation heat exchange equipment, the cleaning liquid is poured into the water tank, and then the water pump pumps the cleaning liquid into the heat exchange equipment. The cleaning liquid cleans the inside of the heat exchange equipment, and after passing through the inside of the heat exchange equipment, it is discharged from the water outlet pipe and flows back to the water tank, and is pumped into the heat exchange equipment again by the water pump for cleaning. Since the discharged cleaning liquid contains foreign matters such as dirt, corrosion, and slime removed from the inner surface of the heat exchange equipment, when it is pumped into the heat exchange equipment again, it is easy to damage the water pump and affect the cleaning efficiency and effect of the heat exchange equipment.

[0003] Therefore, a descaling circulation device for a pressure swing adsorption oxygen generation heat exchange equipment that can filter the cleaning liquid and prevent dirt from flowing back into the heat exchange equipment has been developed. Content of the Utility Model

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] The following details the preferred technical solutions of the present utility model with reference to the accompanying drawings.

[0020] A descaling circulation device for a heat exchange equipment in pressure swing adsorption oxygen production, as Figure 1 and Figure 2 shown, comprising a support base 1, a circulation water pump 2, a water suction pipe 3, a water outlet pipe 4, a water discharge pipe 5 and a filtering mechanism 6. The upper side of the right part of the support base 1 is connected with the circulation water pump 2. The left side of the circulation water pump 2 is connected with the water suction pipe 3. The upper side of the circulation water pump 2 is connected with the water outlet pipe 4. The front side of the left part of the support base 1 is connected with the water discharge pipe 5. Threaded joints are provided on the upper sides of the water outlet pipe 4 and the water discharge pipe 5 for easy connection. A filtering mechanism 6 is provided on the support base 1.

[0021] As Figure 1 、 Figure 3 and Figure 4 shown, the filtering mechanism 6 comprises a filter plate 61, a support frame 62, an electric push rod 63, a piston plate 64, a rotating piece 65 and a torsion spring 66. The filter plate 61 is clamped on the left part of the support base 1. The filter plate 61 is located on the left side of the water suction pipe 3. The upper side of the left part of the support base 1 is connected with the support frame 62. The middle of the support frame 62 is connected with the electric push rod 63. The telescopic end of the electric push rod 63 is connected with the piston plate 64. The piston plate 64 contacts with the filter plate 61. The piston plate 64 is slidably connected with the support base 1. The rotating piece 65 is rotatably connected to the inner side of the front part of the left part of the support base 1. The rotating piece 65 fits with the support base 1. The rotating piece 65 is located at the water outlet of the water discharge pipe 5. A torsion spring 66 is connected between the rotating piece 65 and the support base 1.

[0022] When using the present utility model, first place the support base 1 in the descaling area of the pressure swing adsorption oxygen generation heat exchange equipment. Then, mix the descaling agent ZJ-821 and water in a certain proportion to form a cleaning liquid, and pour the cleaning liquid into the support base 1. After that, connect the water outlet pipe 4 and the water discharge pipe 5 to the inlet and outlet of the heat exchange equipment respectively through a hose. After the connection is completed, start the circulating water pump 2, so that the circulating water pump 2 pumps the cleaning liquid into the water outlet pipe 4, and then injects the cleaning liquid into the heat exchange equipment through the water outlet pipe 4, so that the cleaning liquid fully contacts the inner surface of the heat exchange equipment, effectively removing foreign matters such as dirt, corrosion, and slime on the inner surface of the heat exchange equipment. After the cleaning liquid cleans the heat exchange equipment, it flows back to the support base 1 from the water discharge pipe 5. The circulating water pump 2 makes the cleaning liquid circulate inside the heat exchange equipment until the heat exchange equipment is completely cleaned. When the cleaning liquid flows from the water discharge pipe 5 into the support base 1, the filter plate 61 filters the cleaning liquid pumped into the water suction pipe 3, so that the dirt in the cleaning liquid remains in the support base 1, thus playing a role in filtering the cleaning liquid and preventing the dirt from flowing back into the heat exchange equipment. When the cleaning liquid is discharged from the water discharge pipe 5, the cleaning liquid pushes out the rotating piece 65, and the torsion spring 66 deforms. When the speed of the cleaning liquid passing through the filter plate 61 is slow, start the electric push rod 63 on the support frame 62 to push the piston plate 64 downward to pressurize the inside of the support base 1, accelerating the cleaning liquid to pass through the filter plate 61. When the pressure in the support base 1 and the water discharge pipe 5 is balanced, the piston plate 64 rotates and adheres tightly to the support base 1, and the torsion spring 66 resumes, preventing the cleaning liquid from flowing back into the heat exchange equipment.

[0023] As Figure 1 and Figure 5 shown, it further includes a cleaning mechanism 7. The cleaning mechanism 7 includes a sliding frame 71, a cleaning strip 72 and an elastic member. The right part of the piston plate 64 is slidably connected with the sliding frame 71. The lower side of the sliding frame 71 is connected with the cleaning strip 72. The cleaning strip 72 contacts the filter plate 61. Elastic members are provided between the front and rear parts of the sliding frame 71 and the piston plate 64, and the elastic members are springs 73.

[0024] Using the cleaning mechanism 7 of the present device, the filter plate 61 can be cleaned. When the piston plate 64 moves downward, it drives the sliding frame 71 to move downward, so that the cleaning strip 72 moves on the filter plate 61, thus playing a role in cleaning the filter plate 61 and preventing the filter plate 61 from being blocked. When the cleaning strip 72 contacts the support base 1 and the piston plate 64 continues to move downward, the spring 73 is stretched to avoid affecting the pressurization of the piston plate 64. After the cleaning liquid passes through the filter plate 61, the piston plate 64 is reset, so that the spring 73 rebounds and drives the sliding frame 71 to reset.

[0025] The above has introduced the present application in detail. Specific examples are used herein to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea; at the same time, for those of ordinary skill in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
