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

Embodiment 1

[0021] Embodiment 1: a kind of chlorine passing device that adopts liquid chlorine to produce tin protochloride (referring to Figure 1 ~ Figure 2 ), including liquid chlorine bottle 1, coil pipe 6, heating water tank 5 and chlorine buffer tank 8, liquid chlorine bottle is placed on metering scale 14, steam pipe 53 is passed into the heating water tank, and the outer surface of heating water tank 5 is arranged There is an insulating layer 52, the bottom of the heating water tank 5 is provided with a blowdown pipe 51, and the top is provided with an overflow pipe 54. The device is also provided with a liquid collecting pipe 3, five connecting pipes 31 provided with angle valves 32 are installed on the collecting pipe, and the coil inlet 61 communicates with the liquid chlorine bottle 1 through the liquid collecting pipe, that is, the liquid chlorine bottle 1 communicates with one of the connecting pipes 31 on the liquid collection pipe through the copper pipe 2, and the liquid ...

Embodiment 2～ Embodiment 6

[0024] Embodiment 2~Example 6: adopt the method for passing chlorine through the chlorine device described in embodiment 1, in the working process, liquid chlorine flows into the coil under the action of high pressure in the steel cylinder, and is heated by the hot water outside the coil , to accelerate its gasification, the specific parameters of the process of passing chlorine are as follows.

Embodiment 2

[0025] Example 2: Use a bottle of liquid chlorine bottle (one ton / bottle) filled with liquid chlorine to pass chlorine, the initial pressure of the chlorine buffer tank is 0.002Mpa, open the liquid chlorine bottle to start chlorine flow, control the heating water temperature at about 45°C, and control the buffer Pressure in the tank was 0.12Mpa, and after 6 hours and 50 minutes, the liquid chlorine in the liquid chlorine bottle basically flowed out, and the valve of the liquid chlorine bottle was closed, and the next liquid chlorine bottle was connected to continue chlorine feeding until the chlorination reaction ended.

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 ti...
