Description

Technical Field

[0001] The invention belongs to the technical field of chlorine liquefaction recovery, and in particular relates to chlorine liquefaction recovery equipment. Background Art

[0002] Chlorine liquefaction recovery is a technical process that converts gaseous chlorine into liquid chlorine and recycles it. In chemical production, especially in the chlor-alkali industry, a large amount of chlorine will be produced. If it is discharged directly, chlorine will not only cause a waste of resources, but also seriously pollute the environment because it is a toxic gas that has a strong irritating and corrosive effect on the human respiratory tract, eyes, etc. The principle of chlorine liquefaction recovery is based on the physical state changes of chlorine at different temperatures and pressures. Gaseous chlorine can be converted into liquid by lowering the temperature or increasing the pressure. In actual operation, a combination of cooling and compression is usually used. First, use cooling equipment to cool the chlorine to a certain low temperature, and then use a compressor to increase the pressure of the chlorine to make it reach liquefaction conditions, thereby realizing the transformation from gas to liquid;

[0003] However, when cooling the chlorine, if the worker temporarily opens the closed door, a large amount of cold air will be ejected outwards, causing an impact on the face of the worker opposite. Summary of the Invention

DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0026] like Figure 1-5 As shown, a chlorine liquefaction recovery device of the present invention includes a body 1, a working box 11 is provided on the lower side of the body 1, a refrigeration mechanism is provided in the working box 11, a working chamber 12 is provided in the middle of the body 1, a feed pipe 13 is provided on the upper side of the body 1, the feed pipe 13 is connected to a plurality of round-shaped pipes 14 installed in the working chamber 12, and a drain pipe 15 is commonly connected to the lower side of the plurality of round-shaped pipes 14. A collecting box 16 connected to the drain pipe 15 is provided on the outside of the body 1, a chute 2 extending into the working chamber 12 is provided on one side of the body 1, a box door 21 is slidably installed in the chute 2, and the box door 21 is equipped with an adsorption mechanism facing the working chamber 12, and the adsorption mechanism is used to absorb the cold air in the working chamber 12 when the box door 21 is opened.

[0027] The staff can inject chlorine gas into the plurality of meandering tubes 14 through the feed pipe 13. The chlorine gas can move through the meandering tubes 14. Since the meandering tubes 14 are constantly bent in the working chamber 12, the residence time of the chlorine gas in the working chamber 12 can be increased. At the same time, the refrigeration mechanism can start working, injecting cold air into the working chamber 12 to cool the working chamber 12. Since the chlorine gas is in the meandering tubes 14 and the meandering tubes 14 are inside the working chamber 12, the chlorine gas in the meandering tubes 14 can be cooled. After the chlorine gas is cooled and liquefied, it is discharged from the working chamber 12 through the drain pipe 15 and falls into the collection box 16.

[0028] When the staff needs to open the box door 21 for a while to inspect and maintain the internal components in the working chamber 12, the staff can directly slide the box door 21 to drive the box door 21 to slide outward from the slide groove 2. When the box door 21 gradually exposes the working chamber 12, the adsorption mechanism starts to work. In the process of opening the box door 21, the cold air in the working chamber 12 floats outward. At this time, the adsorption mechanism absorbs the cold air. In this way, a large amount of cold air is absorbed when the box door 21 is opened for the first time, and will not directly impact the staff's face. When the staff closes the box door 21, the adsorption mechanism will spit out the absorbed cold air into the working chamber 12. This design can effectively reduce the cold air loss caused by opening the box door 21.

[0029] Limit grooves 22 are provided on the upper and lower sides of the box door 21, and limit blocks 23 extending into the limit grooves 22 are provided on the upper and lower sides of the opening of the slide groove 2. The adsorption mechanism includes two sliding cavities 24 provided on the upper and lower sides of the box door 21. The two sliding cavities 24 are both slidingly sealed and equipped with magnetic sliders 25. The limit blocks 23 are iron limit blocks. The magnetic sliders 25 can adsorb the limit blocks 23. The outsides of the two sliding cavities 24 are commonly connected to an absorption structure.

[0030] When the staff slides the box door 21 to expose the working chamber 12, the limit block 23 slides relatively in the limit groove 22. During the sliding process of the limit block 23 in the limit groove 22, the inner walls on both sides of the limit groove 22 can block the limit block 23, thereby preventing the box door 21 from separating from the machine body 1. Moreover, since the magnetic slider 25 and the limit block 23 can attract each other, when the box door 21 is opened, the magnetic slider 25 attracts the limit block 23, so the position of the magnetic slider 25 relative to the limit block 23 is fixed, and the magnetic slider 25 is The magnetic slider 25 slides relatively in the sliding cavity 24. When the box door 21 is opened, the space on the left side of the sliding cavity 24 gradually increases, so that a negative pressure can be formed on the left side of the sliding cavity 24, and the negative pressure is transmitted to the absorption structure. The absorption structure can absorb the cold air that is emitted when the box door 21 is opened, and the cold air can be sucked into the sliding cavity 24. When the staff closes the box door 21, the magnetic slider 25 can squeeze the space on the left side of the sliding cavity 25 and squeeze the cold air into the absorption structure. This design can effectively blow the cold air into the working cavity 12 when the box door 21 is closed.

[0031] The absorption structure includes an inner cavity 3 arranged inside the side of the box door 21 away from the opening of the slide 2. The inner wall of the box door 21 is provided with a plurality of suction holes 31 connected to the inner cavity 3. The inner walls of the two sliding cavities 24 on the side close to the opening of the slide 2 are both provided with connecting pipes 32 connected to the inner cavity 3.

[0032] When the negative pressure is formed in the sliding cavity 24, the negative pressure is injected into the inner cavity 3 through the connecting pipe 32, and the negative pressure is transmitted into the air suction hole 31 because the inner wall of the box door 21 is provided with a plurality of air suction holes 31 communicated with the inner cavity 3. Thus, the cold air can be absorbed through the air suction hole 31. When the cold air in the sliding cavity 24 is extruded, the cold air is discharged into the working cavity 12 through the air suction hole 31.

[0033] The vertical frame 33 is provided outside the box door 21, and the distribution cavity 34 is arranged in the vertical frame 33. The connecting hole 35 communicated with the distribution cavity 34 is arranged on the side of the sliding cavity 24 away from the opening of the sliding groove 2. A plurality of air blowing holes 36 are arranged on the side of the vertical frame 33 away from the opening of the sliding groove 2.

[0034] When the box door 12 is opened, the space on the right side of the sliding cavity 24 is gradually reduced, and the gas on the right side of the sliding cavity 24 is injected into the vertical frame 33 through the connecting hole 35, and then is sprayed out through the air blowing hole 36. Thus, when the box door 21 is opened, the space of the working cavity 12 exposed can be closed by the gas through the air blowing hole 36, and the cold air in the working cavity 12 is further prevented from floating out.

[0035] A plurality of refrigeration components corresponding to the plurality of U-shaped pipes 14 are arranged in the working cavity 12. The refrigeration components can directly cool the U-shaped pipes 14, and improve the cooling effect of the chlorine gas in the U-shaped pipes 14.

[0036] The refrigeration component includes two vertical plates 4 arranged in front of and behind the U-shaped pipe 14. The refrigeration cavity connected with the refrigeration mechanism is arranged in each vertical plate 4. The refrigeration hole 42 communicated with the refrigeration cavity is arranged on the opposite side of each vertical plate 4. The cold air generated by the refrigeration mechanism is injected into the refrigeration cavity, and then is blown out from both sides of the U-shaped pipe 14 through the refrigeration hole 42, so as to improve the refrigeration effect of the U-shaped pipe 14.

[0037] The box door 21 is provided with an observation window 43. The observation window 43 is convenient for the staff to observe the cooling effect of the working cavity 12.

[0038] The above embodiments only exemplarily illustrate the principles and effects of the present application, and are not used to limit the present application. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought of the present application should be covered by the claims of the present application.
