specific Embodiment 1

[0057] Specific embodiment one: please refer to Figure 1-16 A reaction device for a continuous piped cyclization process of BIT products, comprising a piped reactor, the piped reactor includes a converging unit 1, a mixing unit 2 and a reaction unit 3 connected in sequence.

[0058] The confluence unit 1 includes a confluence pipe 101 for inputting a liquid reactant A, and the liquid reactant B is sucked into the confluence unit 1 by the suction of the reactant A to form a mixed solution.

[0059] The intersection pipe 101 is provided with a narrow tube area 102, the diameter of which is much smaller than that of other areas, and the upper end of the narrow tube area 102 is connected with a suction pipe 103, which is connected with a liquid storage tank 104 for storing reactant B, and the suction pipe A starting valve is provided in 103 , and when the suction force of the narrow pipe area 102 reaches the starting threshold, the starting valve is opened, and the reactant B flo...

specific Embodiment 2

[0084] Specific embodiment two: on the basis of specific embodiment one, please refer to Figure 17 A kind of reaction equipment of the BIT product continuous pipeline ring closure process, the upper side of the heat preservation pipeline 401 is provided with an air outlet pipe 403, and the air outlet pipe 403 is provided with an air outlet one-way valve 405. The air outlet one-way valve 405 includes an air outlet temperature-sensing blocking sheet 405-1 and an air outlet grille plate 405-2. The air outlet grille plate 405-2 is fixed in the air outlet pipe 403 and communicates with the upper and lower sides. The air outlet temperature-sensing blocking piece 405-1 is made of memory alloy, and the deformation temperature of memory alloy is 50°C. The air outlet temperature sensing blocking sheet 405-1 is placed on the upper side of the air outlet grille plate 405-2. The air outlet temperature-sensing blocking sheet 405-1 is in the form of a cover when the environment is lower t...

specific Embodiment 3

[0085] Specific embodiment three: on the basis of specific embodiment one or two, please refer to Figure 18 A kind of reaction equipment of BIT product continuous pipeline cyclization process, the intersection unit 1 also includes a liquid storage tank 104, and the liquid storage tank 104 stores chlorinated liquid or 30% liquid caustic soda. When ammonia water flows in the narrow tube area 102 , what is stored in the liquid storage tank 104 is chlorinated liquid. When the mixture of ammonia water and chlorinated liquid flows in the narrow tube area 102, what is stored in the liquid storage tank 104 is 30% liquid caustic soda. The suction pipe 103 is a siphon pipe, and a section of the suction pipe 103 is submerged under the liquid level of the liquid storage tank 104 , and the liquid storage tank 104 is higher than the junction pipe 101 . When the liquid in the narrow pipe area 102 flows, the gas in the suction pipe 103 is sucked out until the liquid level at the other end o...

Abstract

The invention discloses a BIT product continuous channelization cyclization process and reaction equipment thereof, and belongs to the field of chemical equipment. Reaction equipment for a BIT product continuous channelization cyclization process comprises an intersection unit, a mixing unit and a reaction unit which are sequentially communicated, the reaction unit comprises a reaction pipeline, a solid reactant C is introduced into the upper end of the reaction pipeline, a plurality of reaction projection are fixedly arranged on the inner bottom wall of the reaction pipeline, the reaction projection support the reactant C, so that after mixed liquid flow past the reaction projection, eddy current is formed, the area where the reaction projection forms the eddy current is an area for supporting a reactant C. According to the invention, large-scale pipeline reaction can be carried out on the production of BIT products, the production speed and the mixing intersection and free control times of ammonia water and chlorination liquid are increased, and the ammonia water and the chlorination liquid are fully mixed; the TDBA is in full contact with a mixed solution in the reaction pipeline, so that the problem that TDBA solid particles are not completely reacted and directly enter a product is effectively avoided.

Description

technical field [0001] The invention belongs to the field of chemical equipment, and more specifically relates to a BIT product continuous pipeline cyclization process and reaction equipment thereof. Background technique [0002] BIT (1,2-Benzisothizolin-3-one), that is, 1,2-benzisothiazolin-3-one, is a widely used fungicide, which can be directly compounded with solvent or combined with other fungicides for special needs Collaborative use. BIT is a fungicide that can be used in most water-based components. It has an outstanding effect of inhibiting the growth of mold (fungi, bacteria), algae and other microorganisms in organic media, and solves the mold and fermentation of organic products caused by microbial growth. , deterioration, demulsification, odor, and a series of problems. Because of its non-volatile and stable characteristics at high temperature, it can be added and used when the liquid temperature is high. BIT has good compatibility with non-ionic and cationic...
