Description

Technical Field

[0001] The utility model relates to the technical field of alkali making industry, in particular to a leakage-proof decomposition device for chlorate. Background Art

[0002] The salts formed by chloric acid contain trigonal pyramidal chlorate ions, in which the oxidation state of the chlorine atom is +5. Chlorate is highly oxidizing, so it should be stored away from organic materials and reducing substances. The current synthesis method is the chemical removal method of chlorate, which uses steam to heat part of the light salt water diverted from electrolysis to 95°C, and then adds 31% hydrochloric acid (acidity of about 2.3 mol / l) to the heated light salt water. The mixed light salt water enters the chlorate decomposition tank, and the chlorate decomposes into chlorine and sodium chloride. During the reaction, chlorine dioxide is produced, which is a flammable and explosive gas and can easily cause production accidents.

[0003] According to the patent website's publication of "An Efficient Chlorate Decomposition Device (Publication Number: CN 208235004U; Application Number: 201820420732.X)", the above application optimizes the problem that: 'At present, the domestic chlor-alkali industry generally adopts a tank-type chlorate decomposition tank, that is, the salt water enters from the bottom of the decomposition tank and overflows from the middle and upper parts. The equipment with this structure has low decomposition efficiency and unstable operation'. However, when the decomposition device in the above application is in use, it is impossible to discharge the chlorine dioxide generated during the reaction in a timely manner, which easily leads to a large amount of chlorine dioxide accumulation and explosion.

[0031] Furthermore, the staff only needs to start the exhaust fan 1102 to drive the air in the material box 3 into the exhaust pipe 1103 for discharge, so that the air in the material box 3 can keep circulating without accumulating too much chlorine dioxide and posing the risk of explosion, thereby increasing the safety of the staff.

[0032] Embodiment 2

[0033] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 On the basis of the first embodiment, it is further obtained that the fixing mechanism 2 includes a locking component 21, a supporting component 22 and a positioning component 23. The locking component 21 is arranged in the front and rear sides of the air filter component 12, the supporting component 22 is arranged in the upper and lower sides of the locking component 21, and the positioning component 23 is arranged in the locking component 21 and the supporting component 22.

[0034] The clamping assembly 21 includes a clamping plate 2101, which is sleeved on the front and rear sides of the fixed frame 1201, and the clamping plate 2101 is clamped on the front and rear sides of the handle 1 1204. The outer side of the clamping plate 2101 is fixedly connected to a fixed cylinder 2102, and the outer side of the fixed cylinder 2102 is fixedly connected to a handle 2 2103. The supporting assembly 22 includes a sleeve 2201, which is arranged on the upper and lower sides of the fixed cylinder 2102, and a fixed block 2202 is fixedly connected to the left side of the sleeve 2201, and the fixed block 2202 is fixedly connected to the right side of the unloading box 3.

[0036] In actual operation, when the device is used, the exhaust fan 1102 is started, and the exhaust fan 1102 is started to extract the air in the material box 3 to the exhaust pipe 1103 for discharge, so that the air containing chlorine dioxide in the material box 3 will not accumulate in the material box 3. After the air in the material box 3 is discharged, the internal air pressure decreases. At this time, the fresh air from the outside enters the material box 3 from right to left to fill the vacancy of the air in the material box 3. Keeping the exhaust fan 1102 started means completing the continuous renewal of the air in the material box 3.

Then the staff pulls the handle 2103 to move outward, and the handle 2103 moves outward to drive the clamping plate 2101 to move outward through the fixed cylinder 2102. The clamping plate 2101 moves outward to disengage from the fixed frame 1201 and the clamping frame 1202. Then the staff can hold the handle 1204 to drive the filter plate 1203 to move to the right. At this time, the disassembly of the filter plate 1203 is completed, and then the above operation can be performed in reverse to install the new filter plate 1203 into the fixed frame 1201.
