Description

Technical Field

[0001] The invention relates to the technical field of chemical product production, in particular to a chlorine treatment mechanism in calcium hypochlorite production. Background Art

[0002] Calcium hypochlorite is mainly produced by the chlorination reaction of calcium hydroxide and chlorine. During the production process, reaction tail gas containing chlorine and dust containing dry calcium hypochlorite powder will be generated. Although the existing calcium hypochlorite production device is equipped with a dust removal device and a tail gas recovery device, a certain amount of dust cannot be recovered. In addition, the recovery rate of the chlorine is not ideal.

[0003] For example, the patent with application number 201420610625.5 discloses an environmentally friendly recovery device for calcium hypochlorite production, which consists of a bag dust collector and a tail gas absorption mechanism. The bag dust collector is connected to a drying mechanism for calcium hypochlorite production, and the tail gas absorption mechanism is connected to a chlorination reactor for calcium hypochlorite production. The technical solution adopted to solve its technical problems is that the tail gas absorption mechanism includes a primary tail gas absorption tower and a secondary tail gas absorption tower, and the solid outlet of the bag dust collector is connected to the drying mechanism. By sending the dust not recovered by the bag dust collector to a water adsorption tower and a dilute hydrochloric acid adsorption tower, the maximum recovery of dust is achieved. At the same time, the chlorine in the tail gas is also recycled in the water adsorption tower and the dilute hydrochloric acid adsorption tower, which not only reduces the environmental emission pressure of the calcium hypochlorite enterprise, but also recovers the useful substances in the tail gas and dust into the production system.

[0004] However, although the above patent can recycle chlorine when treating it, in actual use, the treatment effect is relatively simple, resulting in unsatisfactory chlorine filtering effect, thereby reducing the treatment quality and treatment efficiency of chlorine. Therefore, a chlorine treatment mechanism in calcium hypochlorite production is proposed to solve the above problem. Summary of the invention

[0015] Furthermore, one end of the movable rod located inside the filter bin is rotatably connected to the support plate, and one end of the filter plate located inside the filter bin is provided with a connection groove located outside the support plate.
