Description

Technical Field

[0001] The utility model relates to the technical field of sodium hydroxide production, in particular to a chlorine cooling device used for sodium hydroxide production. Background Art

[0002] The principle of chlorine cooling is mainly to reduce the water vapor content in wet chlorine by lowering the temperature. The main task of the chlorine treatment process is to cool, dry and pressurize the high-temperature wet chlorine. In saturated wet chlorine, the water vapor content is closely related to the temperature. During the cooling process, the wet chlorine passes through the chlorine water washing tower and is sprayed with chlorine water. It then enters the titanium cooler and is cooled to a lower temperature by chilled brine or chilled water. It then passes through the demister to remove the water mist before entering the drying tower.

[0022] The annular tubes 204 are distributed in multiple groups parallel to the central axis of the main tube 203 .

[0023] In this embodiment, when cooling is required, the cold inlet valve block 202 is opened to allow the refrigerant to enter the main pipe 203 through the cold inlet pipe 201. After entering the main pipe 203, the main pipe 203 and the annular pipe 204 absorb the heat inside the box shell 104, and after absorbing the heat, the heat is discharged from the equipment through the heat exhaust pipe 205.

[0024] The load-bearing drainage assembly 1 includes a pad 101, a bottom supporting plate 102, a bolt bracket 103, a box shell 104, an insulation board 105, a top cover 106, an inner plate 107, a duct frame 108, a fin group 109 and a drainage valve port 1010. The top side of the pad 101 is provided with a bottom supporting plate 102, and the top of one end of the bottom supporting plate 102 is bolted to the box shell 104 on which the insulation board 105 is installed through a bolt bracket 103.

[0025] In this embodiment, when in use, the equipment is placed at the processing site through the pad 101, and the box shell 104 and the insulation board 105 are assembled through the bottom supporting plate 102 and the bolt bracket 103 to effectively socket the circulating heat absorption mechanism 2 and the separation compression component 3.

[0027] In this embodiment, after the water is discharged, it falls onto the inclined surface on the inner bottom side of the box shell 104. The output passing through the inclined surface is finally output through the drain valve port 1010 at the output end of the box shell 104, thereby achieving the water discharge effect.

[0028] The separation and compression component 3 includes an inlet 301, an air intake valve block 302, a middle pipe 303, a branch pipe 304, a diffuser 305, a convex side pipe 306, a reverse osmosis membrane group 307, an air outlet valve block 308, a compressor 309 and a gas storage tank 3010.

[0029] In this embodiment, when air intake is required, the air intake valve block 302 is opened, and after opening, the air is input into the middle pipe 303 through the inlet 301, and then the material is distributed through the middle pipe 303 and the branch pipe 304 through the dispersion pipe 305. After distribution, the heat is discharged in cooperation with the fin group 109, and the water is discharged through the convex side pipe 306 and the reverse osmosis membrane group 307 after cooling.

[0030] An air outlet valve block 308 is provided at the output end of the diffuser pipe 305 , a compressor 309 is provided at the output end of the air outlet valve block 308 , and an air storage tank 3010 is provided at the output end of the compressor 309 .

[0031] In this embodiment, after the water is discharged and the product is cooled, the compressor 309 outputs power to drive the output end to operate, so that the gas outlet valve block 308 stores the cooled gas through the storage gas tank 3010.

[0032] The working principle of the chlorine cooling device for sodium hydroxide production is as follows: when in use, the device is placed at the processing site through the pad 101, and the box shell 104 and the insulation board 105 are assembled through the bottom supporting plate 102 in conjunction with the bolt bracket 103, so as to effectively socket the circulating heat absorption mechanism 2 and the separation compression component 3. When cooling is required, the cold inlet valve block 202 is opened to allow the refrigerant to enter the main pipe 203 through the cold inlet pipe 201. After entering the main pipe 203, the main pipe 203 and the annular pipe 204 absorb the heat inside the box shell 104, and after absorbing the heat, the heat is discharged from the equipment through the heat exhaust pipe 205. When air intake is required, the air intake valve block 302 is opened. After opening, the material is input into the middle pipe 303 through the inlet 301, and then the material is distributed through the dispersion pipe 305 through the middle pipe 303 and the branch pipe 304. After distribution, the heat is discharged in cooperation with the fin group 109. After cooling, the water is discharged through the convex side pipe 306 and the reverse osmosis membrane group 307. When the water is discharged, it falls on the inclined surface on the inner bottom side of the box shell 104. The output through the inclined surface is finally output through the drain valve port 1010 at the output end of the box shell 104, thereby achieving the water discharge effect. When the water is discharged and the product is cooled, the power is output by the compressor 309 to drive the output end to operate, so that the gas outlet valve block 308 stores the cooled gas through the storage tank 3010.
