Chlorine introducing method and device for producing stannous chloride by liquid chlorine

Abstract

The invention relates to a chlorine introducing method and a chlorine introducing device, in particular to a chlorine introducing method and a chlorine introducing device for producing stannous chloride by liquid chlorine. The method comprises the following steps of: introducing liquid chlorine into a coiled tube to be heated and gasified, introducing chlorine to a chlorine introducing tank for use, and heating the coiled tube by external hot water at the temperature of between 40 and 60 DEG C. The device comprises a liquid chlorine cylinder, the toiled tube, a heating water tank and a chlorine buffer tank, wherein the coiled tube is arranged in the heating water tank; an inlet of the coiled tube is communicated with the liquid chlorine cylinder, and an outlet of the coiled tube is communicated with the chlorine buffer tank; and the chlorine buffer tank is communicated to the chlorine introducing tank. In the method and the device, an operating mode of the natural gasification of the liquid chlorine is changed, and the liquid chlorine is introduced into the coiled tube in liquid mode and is heated by utilizing the coiled tube to accelerate the gasification speed of the liquid chlorine and improve the efficiency of a chlorination reaction in stannous chloride production; and the requirement of the production on the speed of a chlorine introducing reaction can be met only by opening one cylinder of liquid chlorine (one ton / cylinder), and the reliability of safety performance of the liquid chlorine during use is enhanced.

Description

technical field [0001] The invention relates to a method and device for passing chlorine, in particular to a method and device for passing chlorine to produce stannous chloride by using liquid chlorine. Background technique [0002] The traditional chlorine flow process for stannous chloride production is: liquid chlorine is naturally gasified in steel cylinders, and the gasification speed is slow. After a long time, multiple bottles of liquid chlorine (1 ton / bottle) must be opened at the same time to meet the stannous chloride production. . There are big flaws in this method: [0003] 1. Because the gasification of liquid chlorine needs to absorb a large amount of heat from the air through the steel cylinder, after a period of time when the liquid chlorine is gasified, a thick layer of ice will form on the surface of the steel cylinder, which will affect the transfer of heat, resulting in a very slow gasification speed of liquid chlorine and prolonged Chlorine reaction t...

Problems solved by technology

[0003] 1. Because the gasification of liquid chlorine needs to absorb a large amount of heat from the air through the steel cylinder, after a period of time when the liquid chlorine is gasified, a thick layer of ice will form on the surface of the steel cylinder, which will affect the transfer of heat, resulting in a very slow gasification speed of liquid chlorine and prolonged Shorten the chlorine reaction time, reduce production efficiency

[0004] 2. In order to ensure that the chlorine reaction can be completed quickly, more than 5 bottles of liquid chlorine must be opened at the same time during the production operation. The number of steel cylinders opened at the same time and the frequency of operation are too many, resulting in a large amount of liquid chlorine stored on site and frequent opening and closing of needle valves. It is easy to cause many safety hazards and other problems

It reduces the reliability of chlorine safety performance and increases the management difficulty of safety production
