Brominating kettle with external double-layer temperature control structure for bromothalonil processing

Abstract

The invention discloses a bromination kettle with an external double-layer temperature control structure for bromothalonil processing, and relates to the technical field of reaction kettles. The outer kettle body is sleeved and fixed on the kettle body, and the discharge pipe is arranged at the bottom of the outer kettle body in a penetrating manner; the annular water pipes are distributed at equal intervals, sleeve and are fixed on the kettle body, and heating rods are arranged in the annular water pipes; the connecting water pipes penetrate through and are fixed to the right ends of the annular water pipes, the connecting water pipes penetrate through the right side wall of the outer kettle body and then are arranged on the right side of the outer kettle body, and control valves are arranged at the right ends of the connecting water pipes; the supporting water pipe is arranged on the right side of the outer kettle body, the right end of the connecting water pipe is inserted and fixed in the supporting water pipe, and the supporting water pipe is connected with an external water source through a water pump by a water inlet pipe on the upper side; through the arrangement of the double-layer kettle body, the temperature in the kettle body is controlled according to the actual processing condition when the inside of the kettle body is processed, so that processing substances in the kettle body fully react, and the reaction efficiency and quality are improved.

Description

technical field [0001] The invention relates to the technical field of reaction kettles, in particular to a bromination kettle for bromoxynil processing with an external double-layer temperature control structure. Background technique [0002] Bromoxanil is a broad-spectrum, low-toxicity fungicide, which can inhibit and eradicate the growth of fungi, bacteria and algae, has a good control effect on crop diseases, and has special effects on anthracnose; It is necessary to carry out the reaction operation in the reaction kettle during production; most of the existing reaction kettles are single-layer tanks. When the reaction kettle is in chemical reaction, the temperature adjustment method is usually the method of directly installing a heater in the reaction chamber to directly adjust the temperature of the reactor. When the feed liquid is heated, the heat distribution is uneven, which leads to uneven heating of the feed liquid, and a large amount of heat is generated during t...

Problems solved by technology

[0002] Bromothalonil is a broad-spectrum, low-toxic fungicide, which can inhibit and eradicate the growth of fungi, bacteria, and algae. It has a good control effect on crop diseases and has special effects on anthracnose; bromothalonil is corrosive, The reaction operation needs to be carried out in the reaction kettle during production; most of the existing reaction kettles are single-layer tanks. When the reaction kettle is used in chemical reactions, the temperature adjustment method is usually to install a heater directly in the reaction chamber. The material liquid is heated, and there is an uneven distribution of heat, which leads to uneven heating of the material liquid, and a large amount of heat is generated during the dissolution process, which makes it impossible to quickly control the temperature of the reactor, which affects the efficiency of the reaction and the quality of the product.
