Description

Technical Field

[0001] This utility model relates to the technical field of MVR evaporation treatment systems, and in particular to a separator for MVR evaporation treatment systems. Background Technology

[0002] MVR evaporation treatment system is a highly efficient and energy-saving evaporation solution widely used in chemical, pharmaceutical, and environmental protection industries. This system uses mechanical vapor recompression technology to compress the secondary steam generated by the evaporator, increase its temperature and pressure, and then return it to the evaporator as heating steam, recycling the latent heat of the steam and significantly reducing energy consumption. Its core equipment includes an evaporator, a separator, and a compressor. During operation, the solution to be treated is heated and evaporated in the evaporator, and the generated steam is separated into gas and liquid in the separator. The separated pure steam is pressurized and heated by the compressor and used to heat the solution, while the concentrated liquid is discharged from the system for further processing.

[0003] In daily operation, it has been found that the separators or pipes in existing evaporation systems are prone to clogging. Factors causing this clogging include: crystallization of soluble inorganic salts (e.g., sodium sulfate, sodium carbonate), which crystallize and precipitate under supersaturated conditions, causing blockages in the separators or pipes; and fiber and silt deposition: large amounts of fibrous materials and silt in industrial wastewater can deposit in the MVR evaporator, forming sediment and clogging the pipes. Once clogging occurs, the separator cannot function properly, affecting the separation efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem of pipe blockage in the prior art, and to propose a separator for MVR evaporation treatment systems.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a separator for an MVR evaporation treatment system, comprising a separator body, an inlet fixedly connected to the surface of the separator body, a steam outlet and a liquid outlet fixedly connected to both the upper and lower sides of the separator body, a protective device provided at one end of the inlet, the protective device including an auxiliary pipe located at one end of the inlet, a connecting pipe provided at the other end of the auxiliary pipe, an installation part for installing the auxiliary pipe provided between the auxiliary pipe, the inlet and the connecting pipe, an interception net provided on the inner wall of the auxiliary pipe, and a buffer part for buffering the interception net. Through the above components, the auxiliary pipe can be installed between the connecting pipe and the inlet through the installation part. Subsequently, during system operation, impurities carried by the steam enter the auxiliary pipe, which can be effectively intercepted by the interception net, while the buffer part can buffer and protect the interception net.

[0006] Preferably, the mounting part includes two threaded caps fitted onto the surface of the auxiliary pipe, and one end of the inlet and the connecting pipe are fixedly connected with threaded heads. The threaded caps are threadedly connected to the threaded heads. Through the above components, the threaded caps and threaded heads can be connected to each other, thereby installing the auxiliary pipe between the inlet and the connecting pipe.

[0007] Preferably, the buffer section includes a support frame fixed in the inner wall of the auxiliary tube. Multiple hollow sliding sleeves are fixedly connected to the surface of the support frame, and multiple sliding rods are fixedly connected to the surface of the interception net. The sliding rods are slidably connected to the inner wall of the hollow sliding sleeves, and a buffer spring is fixedly connected to the side of the sliding rod corresponding to the inner wall of the hollow sliding sleeve. Through the above components, when the interception net is subjected to impact force, the buffer spring can buffer the interception net, and at the same time, the support frame can support and reinforce the interception net.

[0008] Preferably, the support frame is arranged in a cross shape.

[0009] Preferably, the auxiliary pipe is inclined between the connecting pipe and the inlet. Through the above-mentioned components, the inclined auxiliary pipe can better allow the liquid to flow into the separator body.

[0010] Preferably, the surface of the inlet is provided with an auxiliary component, which includes a sliding frame fixed to the surface of the inlet. A shielding iron plate is slidably connected to the surface of the sliding frame. With the above-mentioned component, when the auxiliary tube is disassembled, the shielding iron plate can slide in the sliding frame to shield the inlet and reduce the entry of impurities.

[0011] Preferably, a magnetic strip is fixedly connected to the surface of the sliding frame, and the magnetic strip is magnetically connected to the shielding iron plate. Through the above-mentioned components, the shielding iron plate can be positioned by the magnetic strip, thereby ensuring stability.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] In this invention, by setting up a protective device, the auxiliary pipe can be installed between the inlet and the connecting pipe through the installation part. The interception net in the auxiliary pipe can effectively block impurities carried by the steam and prevent them from entering the separator body, greatly reducing the risk of separator blockage and ensuring stable system operation. The buffer part can also provide buffer protection for the interception net.

[0014] In this invention, by setting an auxiliary component at the inlet, when the auxiliary tube is disassembled, the inlet can be blocked by a sliding shielding iron plate, reducing the entry of external impurities. The magnetic strip positioning ensures the stability of the shielding iron plate and maintains the cleanliness of the system. Attached Figure Description

[0023] In this embodiment, the separator body 1 is provided with a wire mesh demister and a liquid diversion section.

[0024] Specifically, the protective device 5 includes an auxiliary pipe 51 located at one end of the inlet 2, a connecting pipe 52 at the other end of the auxiliary pipe 51, a mounting part for installing the auxiliary pipe 51 between the auxiliary pipe 51, the inlet 2 and the connecting pipe 52, an intercepting net 55 on the inner wall of the auxiliary pipe 51, a buffer part for buffering the intercepting net 55 on the inner wall of the auxiliary pipe 51, and the auxiliary pipe 51 is inclined between the connecting pipe 52 and the inlet 2.

[0025] In this embodiment, the auxiliary pipe 51 can be installed between the connecting pipe 52 and the inlet 2 through the installation part. Then, during the operation of the system, the impurities carried by the steam enter the auxiliary pipe 51, and the interception net 55 can effectively intercept them. At the same time, the buffer part can buffer and protect the interception net 55. The inclined auxiliary pipe 51 can better allow the liquid to flow into the separator body 1.

[0026] Specifically, the installation part includes two threaded caps 53 fitted on the surface of the auxiliary tube 51. One end of the inlet 2 and the connecting tube 52 are fixedly connected with a threaded head 54. The threaded caps 53 and the threaded heads 54 are threadedly connected. The auxiliary tube 51 can be installed between the inlet 2 and the connecting tube 52 by connecting the threaded caps 53 and the threaded heads 54.

[0027] Specifically, the buffer section includes a support frame 56 fixed in the inner wall of the auxiliary tube 51. Multiple hollow sliding sleeves 57 are fixedly connected to the surface of the support frame 56. Multiple sliding rods 58 are fixedly connected to the surface of the interception net 55. The sliding rods 58 are slidably connected to the inner wall of the hollow sliding sleeves 57. A buffer spring 59 is fixedly connected to the side of the sliding rod 58 corresponding to the inner wall of the hollow sliding sleeve 57. The support frame 56 is arranged in a cross shape.

[0028] In this embodiment: when the interception net 55 is subjected to an impact force, the buffer spring 59 can buffer the interception net 55, and at the same time the support frame 56 can support and reinforce the interception net 55.

[0029] Specifically, an auxiliary component 6 is provided on the surface of the inlet 2. The auxiliary component 6 includes a sliding frame 61 fixed on the surface of the inlet 2. A shielding iron plate 62 is slidably connected to the surface of the sliding frame 61. A magnetic strip 63 is fixedly connected to the surface of the sliding frame 61. The magnetic strip 63 is magnetically connected to the shielding iron plate 62.

[0030] In this embodiment: after the auxiliary tube 51 is disassembled, the shielding iron plate 62 can slide in the sliding frame 61. The shielding iron plate 62 can block the inlet 2 to reduce the entry of impurities. The magnetic strip 63 positions the shielding iron plate 62 to ensure stability.

[0031] Working principle: During operation, steam enters the connecting pipe 52 and auxiliary pipe 51 before entering the inlet 2 of the separator body 1. The intercepting net 55 in the auxiliary pipe 51 can intercept impurities carried by the steam. During the interception process, the intercepting net 55 will be subjected to a certain impact force. When subjected to impact, the sliding rod 58 can move in the hollow sliding sleeve 57. At the same time, the buffer spring 59 can provide buffer protection, and the support frame 56 provides support. Due to the inclined auxiliary pipe 51, the liquid can enter the separator body 1 better. When disassembling the auxiliary pipe 51, simply rotate the threaded cap 53 to remove it from the threaded head 54. After the auxiliary pipe 51 is disassembled, the shielding iron plate 62 can slide in the sliding frame 61. The shielding iron plate 62 can block the inlet 2 to reduce the entry of impurities. The magnetic strip 63 positions the shielding iron plate 62 to ensure stability.
