Description

Technical Field

[0002] In industries such as chemical and petrochemical, heat exchangers with high temperature, high pressure, high temperature differential stress, and large diameter are widely used. In high-pressure synthesis processes in the chemical field, such as methanol synthesis and ammonia synthesis, these heat exchangers are indispensable. The cold and hot gases of the synthesis gas require heat exchange, and the gas pressure is extremely high, reaching over 16.5 MPa. In such high-pressure applications, high-pressure plate heat exchangers are generally used.

[0003] Currently, high-pressure plate heat exchangers require regular cleaning during use. However, due to the need to withstand relatively high pressures, the distance between the heat dissipation support plates in existing high-pressure plate heat exchangers is relatively small. Therefore, cleaning the heat dissipation support plates one by one is necessary, which is time-consuming and labor-intensive, increases the trouble for staff, reduces the efficiency of cleaning the heat exchanger structure, and also reduces the practicality of the heat exchanger structure.

A rotating shaft 204 is symmetrically rotatably connected to the inner wall of the through holes 203. One end of the rotating shaft 204 is fixedly connected to the side surface of the heat exchange tubes 202.

A second driving mechanism is provided on one side of the swing plate 2010. A support frame 1 is fixedly installed on the outer side of the base 2.

[0023] As a technical optimization of this utility model, the cleaning mechanism includes brush plate I 404 and brush plate II 406. Brush plate I 404 is located in the middle of the heat dissipation support plate 201. Support rods 405 are fixedly connected to both ends of brush plate I 404. Support rods 405 are fixedly connected to the inner surface of the horizontal plate 4. An L-shaped support rod 403 is fixedly connected to one side surface of brush plate II 406. One end of the L-shaped support rod 403 is fixedly connected to the surface of the horizontal plate 4. The cleaning mechanism can uniformly clean the side surface of the heat dissipation support plate 201, thus avoiding the need for workers to clean each heat dissipation support plate 201 individually, improving the cleaning efficiency of the heat exchanger structure and reducing the trouble for workers.

[0024] As a technical optimization of this utility model, the first driving mechanism includes a driving plate 302. One end of the driving plate 302 is fixedly connected to the outer surface of one of the sets of horizontal plates 4. A reciprocating screw 3 is threadedly connected inside the driving plate 302. The lower end of the reciprocating screw 3 is fixedly connected to the inner wall of the support frame 1. The upper end of the reciprocating screw 3 passes through the support frame 1 and is fixedly connected to a motor II 301. The reciprocating screw 3, the driving plate 302 and the motor II 301 in the first driving mechanism can drive the cleaning mechanism to move up and down along the heat dissipation support plate 201 to clean the heat dissipation support plate 201.

[0025] As a technical optimization of this utility model, the limiting mechanism includes symmetrically arranged limiting plates 401. One end of the limiting plate 401 is fixedly connected to the outer surface of another set of horizontal plates 4. The limiting rod 402 is slidably connected inside the limiting plate 401.

The limiting plate 401 and the limiting rod 402 can limit the horizontal plate 4, thereby improving the operational stability of the horizontal plate 4 and the cleaning mechanism, and further improving the cleaning effect on the heat exchange structure.

[0026] As a technical optimization of this utility model, the second driving mechanism includes a side plate 205. One end of the side plate 205 is fixedly connected to the outer surface of the swing plate 2010. A keyway hole 206 is provided inside the side plate 205.

A motor I 208 is fixedly connected to the lower surface of the turntable 209. The motor I 208 is fixedly connected to the inner wall of the support frame 1. Through the cooperation of the motor I 208, the turntable 209 and the side plate 205 in the second driving mechanism, the heat dissipation support plate 201 in the heat exchanger structure can be driven to swing back and forth when the heat dissipation support plate 201 is not cleaned. Therefore, the air flow around the heat dissipation support plate 201 can be accelerated, and the heat dissipation effect of the heat dissipation support plate 201 can be further improved.

[0027] As a technical optimization of this utility model, a heat dissipation hole 101 is provided inside the upper end of the support frame 1, and the heat dissipation hole 101 corresponds to the upper end of the heat dissipation support plate 201.

[0028] A heat exchanger device specifically designed for high-pressure applications, comprising a heat exchanger structure.

[0029] When this utility model is in use, if it is necessary to clean the heat dissipation support plate 201 in the heat exchanger structure, the motor II 301 in the first drive mechanism is first started. At this time, the motor II 301 drives the reciprocating screw 3 to rotate. Therefore, the reciprocating screw 3 drives the horizontal plate 4 to move up and down along the reciprocating screw 3 through the drive plate 302. Then, the horizontal plate 4 drives the brush plate I 404 and brush plate II 406 to move along the heat dissipation support plate 201 through the L-shaped support rod 403 and support rod 405, thereby uniformly cleaning the surface of the heat dissipation support plate 201 and reducing the workload. To reduce the inconvenience to personnel and improve the cleaning efficiency of the heat dissipation support plate 201, after cleaning, when using the heat exchanger, the staff starts the motor I 208 in the second drive mechanism. The motor I 208 drives the turntable 209 and the drive block 207 to rotate. Then, the drive block 207 drives the swing plate 2010 to move back and forth through the keyway hole 206 and the side plate 205. After that, the swing plate 2010 drives the heat dissipation support plate 201 to swing left and right, increasing the airflow around the heat dissipation support plate 201, thereby further improving the heat exchange efficiency of the heat exchanger structure.
