Problems solved by technology

After the liquid chlorine is heated by the gasifier, it is vaporized into chlorine gas. After absorbing the heat, the chlorine gas enters the reaction vessel, and additional cooling capacity is required to remove the heat brought by the chlorine gas. The cooling process requires a lot of energy.

Abstract

The invention discloses a device for chlorination reaction directly adopting industrial liquid chlorine. The device is characterized in that the discharge opening of a liquid chlorine steel cylinder (1) is connected with a buffer tank (13) and a reaction kettle (15) in sequence through a main delivery pipe; valves A (3) are arranged at the discharge opening; a liquid chlorine weighing scale (2) is arranged below the liquid chlorine steel cylinder (1); a needle valve (4), a pneumatic valve (7) and a flowmeter (9) are arranged on the main delivery pipe at the front end of the buffer tank (13) in sequence; a pressure gauge A (18) is arranged on the buffer tank (13); a one-way valve (14), a pneumatic valve (20) and a by-pass valve B (24) are arranged between the buffer tank (13) and the reaction kettle (15); a pressure gauge B (17) and a temperature gauge (16) are arranged on the reaction kettle (15). The device for chlorination reaction directly adopting industrial liquid chlorine provided by the invention is convenient to operate, stable, safe, reliable and low in operating cost; besides, the using safety and reliability of liquid chlorine are improved, and meanwhile the operation is more convenient and controllable.

Description

technical field [0001] The invention relates to a device for directly using industrial liquid chlorine in chlorination reaction. Background technique [0002] Industrial liquid chlorine is a yellow-green liquid, a strong oxidant, widely used in papermaking, textiles, pesticides, organic synthesis, metal smelting, chemical raw materials and other fields. [0003] In the field of organic synthesis, liquid chlorine is generally used after gasification. The liquid chlorine coming out of the liquid phase port of the steel cylinder enters the calandria gasifier through the pneumatic control valve. The gasifier is heated with hot water, and the liquid chlorine becomes chlorine gas after heating and gasification. Enter the chlorination reaction system. [0004] There are many disadvantages in the use of liquid chlorine gasification. One is that the calandria gasifier is very prone to corrosion during use. The common ones are crevice corrosion, pitting corrosion, and stress cracking...
