Description

Technical Field

[0001] The utility model relates to the field of trichloroisocyanuric acid production, in particular to a cooling device for trichloroisocyanuric acid production. Background Technique

[0002] Trichloroisocyanuric acid is one of the chlorinated isocyanuric acid series products, abbreviated as TCCA. The pure product is a powdery white crystal, slightly soluble in water and easily soluble in organic solvents. Trichloroisocyanuric acid is a replacement product for bleaching powder and bleaching essence. The three wastes are greatly reduced compared with bleaching essence. With its increasingly wide application, the market demand is also getting higher and higher.

[0003] At present, the production process of trichloroisocyanuric acid mainly uses cyanuric acid, caustic soda and chlorine as raw materials. The reaction principle is as follows: cyanuric acid and caustic soda are formulated into trisodium cyanurate according to the molar ratio. After salting, the slurry is fed with chlorine gas in a chlorination kettle, and a chlorination reaction is carried out at an appropriate temperature to generate trichloroisocyanuric acid and sodium chloride. Trichloroisocyanuric acid needs to cool the solution before subsequent centrifugal washing, but the existing cooling equipment has a large water consumption and is also prone to leakage of polluted water.

[0014] (III) Beneficial effects

[0015] The utility model provides a cooling device for the production of trichloroisocyanuric acid. It has the following beneficial effects:

[0016] 1. For the cooling device for the production of trichloroisocyanuric acid, by setting the water cooling assembly and the uric acid circulation mechanism, the cooling water in the water tank can circulate in the two outer shells. When trichloroisocyanuric acid passes through the water cooling pipes and through the inside of the outer shell, heat is taken away. The lower outer shell is first connected to the cooling water with a lower temperature, so that trichloroisocyanuric acid can be basically cooled when passing through the lower water cooling assembly. And after trichloroisocyanuric acid fills the first outer shell, it will rise along the overflow pipe and then be discharged into the lower outer shell along the one-way pipe. The upper water inlet pipe can release the pressure of trichloroisocyanuric acid and make its temperature drop rapidly. The bottom water inlet pipe can slow down the flow rate of trichloroisocyanuric acid, so that the water cooling pipes inside the lower outer shell are filled with trichloroisocyanuric acid and are fully cooled. The cooling water in the upper water tank is replaced when it reaches a certain temperature. Thus, trichloroisocyanuric acid can be cooled with a small water consumption.

[0017] 2. The cooling device for the production of trichloroisocyanuric acid, by setting an overflow pipe and an exhaust pipe, when the trichloroisocyanuric acid in the overflow pipe flows into the inside of the overflow pipe, it is discharged through the one-way pipe without completely filling the overflow pipe. The one-way pipe can prevent the backflow of trichloroisocyanuric acid and can also increase the pressure below the one-way pipe, increasing the pressure in the lower outer shell, so that the water-cooling pipe is filled with trichloroisocyanuric acid. And the poisonous gas in the overflow pipe can be integrated into the water tank through the exhaust pipe and adsorbed by the cooling water in the water tank. Thus, waste gas leakage can be avoided. If the heating rate of the cooling water in the water tank is slow, then a large amount of polluted water can be avoided under the premise of less consumption of cooling water.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] It should be noted that all the directional indications in the embodiments of the present application are only used to explain the relative positional relationship, movement conditions, etc. between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0026] An embodiment of the utility model provides a cooling device for the production of trichloroisocyanuric acid:

[0027] As Figures 1-5 shown, it includes two water-cooling components 1. The upper water-cooling component 1 is horizontally arranged, and the lower water-cooling component 1 is inclined. The upper end of the lower water-cooling component 1 is connected to the upper water-cooling component 1 by a water pipe A2; it also includes a water tank 3. An exhaust port 4 is provided at the upper end of the water tank 3. The other end of the upper water-cooling component 1 is connected to the bottom of the water tank 3 by a water pipe B5. The side surface of the upper end of the water tank 3 is connected to the other end of the lower water-cooling component 1 by a water pipe C6. The water pipe C6 can extract the cooling water inside the water tank 3 for circulating the two water-cooling components 1; it also includes a uric acid circulation mechanism 7, which is connected to one end of each of the two water-cooling components 1 at both ends, communicates with the two, and is also connected to the water tank 3, for transferring the waste gas inside the uric acid circulation mechanism 7 into the water tank 3.

[0028] A heat dissipation device is installed on the water tank 3, including heat dissipation fins, a fan and a circulation device, for ensuring that the cooling water in the water tank 3 heats up slowly. A circulation pump is installed inside the water pipe C6.

[0029] The water-cooling component 1 includes two connecting plates 101; it includes a number of water-cooling pipes 102, all of which are between the two connecting plates 101. Both ends of the water-cooling pipes 102 are fixed to the two connecting plates 101 respectively and penetrate through the two connecting plates 101; it includes a housing 103. The connecting plates 101 and the water-cooling pipes 102 are both inside the housing 103, and the connecting plates 101 are fixed to the housing 103; it includes a water inlet pipe 104. One end of the water inlet pipe 104 is fixed to the housing 103 and communicates with it. The water pipes A2, B5 and C6 are all installed on the housing 103.

[0030] The water-cooling pipes 102 are densely arranged in an array and have a small diameter, which can enable the cooling water to fully cool each water-cooling pipe 102.

[0031] The water inlet pipe 104 is in a flared structure, and its large end is connected to the housing 103 and covers the outside of the connecting plate 101.

[0032] The water inlet pipe 104 of the upper water-cooling component 1 can suddenly release high-pressure trichloroisocyanuric acid, so that its temperature is reduced. The diameter of the lower water inlet pipe 104 needs to be larger than that of the upper water inlet pipe 104.

[0033] The uric acid circulation mechanism 7 includes an overflow pipe 701, which is connected to one end of the housing 103 of the upper water cooling component 1 away from the water inlet pipe 104 and is communicated with the inside of the housing 103; includes an exhaust pipe 702, which is connected to the upper end of the overflow pipe 701, and the other end is inserted into the bottom of the water tank 3; includes a one-way pipe 704, one end of which is connected to the upper side wall of the upper end of the overflow pipe 701, and a one-way component 705 is installed at the other end; further includes an S-shaped pipe 703, one end of which is connected to the one-way component 705, and the other end is connected to the housing 103 of the lower water cooling component 1.

[0034] The diameters of the overflow pipe 701 and the one-way pipe 704 are both relatively large and are filled with air inside, which can enable trichloroisocyanuric acid to flow naturally without being full.

[0035] The overflow pipe 701 is of an L-shaped structure. The end close to the housing 103 is arranged horizontally, and the end away from the housing 103 is arranged vertically upward.

[0036] The one-way component 705 includes a box body 7051, a cut-off plate 7052 and a down pipe 7053. The box body 7051 is respectively connected to the one-way pipe 704 and the S-shaped pipe 703. The cut-off plate 7052 is inside the box body 7051. The down pipe 7053 is fixed at the bottom end of the cut-off plate 7052, and its inside penetrates through the cut-off plate 7052. A cover plate 7054 is elastically hinged to the bottom end of the down pipe 7053.

[0037] A make-up water pipe 8 is also installed on the water tank 3.

[0038] When the cooling water in the water tank 3 becomes hot, the make-up water pipe 8 can be used to replace the cooling water.

[0039] During use, before washing with trichloroisocyanuric acid, it needs to be cooled. The cooling water in the water tank 3 can circulate within the two outer casings 103. Heat dissipation devices can also be installed on the water tank 3 to prevent the cooling water in the water tank 3 from heating up too quickly. When the trichloroisocyanuric acid passes through the water-cooling pipe 102 and through the outer casing 103, its heat is carried away. The lower outer casing 103 is first connected to the cooling water with a lower temperature. Thus, the trichloroisocyanuric acid can be basically cooled when passing through the lower water-cooling assembly 1. And after the trichloroisocyanuric acid fills the first outer casing 103, it will rise along the overflow pipe 701. When the trichloroisocyanuric acid in the overflow pipe 701 flows into the interior of the overflow pipe 701, it is discharged through the one-way pipe 704 before being completely filled. The one-way pipe 704 can prevent the trichloroisocyanuric acid from flowing back and can also increase the pressure below the one-way pipe 704, increasing the pressure in the lower outer casing 103 to fill the water-cooling pipe 102 with trichloroisocyanuric acid. And the poisonous gas in the overflow pipe 701 can be incorporated into the water tank 3 through the exhaust pipe 702 and adsorbed by the cooling water in the water tank 3. The upper water inlet pipe 104 in the form of pumping can release the pressure of the trichloroisocyanuric acid and rapidly reduce its temperature. The bottom water inlet pipe 104 can slow down the flow rate of the trichloroisocyanuric acid to fill the water-cooling pipe 102 in the lower outer casing 103 with trichloroisocyanuric acid for sufficient cooling.
