Embodiment Construction

[0009] Embodiments of the present invention: as shown in Figure 1, the liquid chlorine storage tank 1 has a capacity of 40t to 80t, generally 60t. The number of liquid chlorine storage tanks is determined according to the amount of liquid chlorine required for production and the distance to the supply of liquid chlorine. The liquid chlorine storage tank is placed in the basement, one storage tank and one room, the rooms are reinforced concrete partition walls, and the basement roof is covered with insulation materials. The liquid chlorine transport tanker unloads the liquid chlorine into the liquid chlorine storage tank 1 in the basement. Depending on the pressure in the tank, the liquid chlorine is pressed into the evaporator 2, and the produced chlorine gas comes out from the top of the evaporator 2, enters the buffer tank 3 and the distributor 4 in turn, and is sent to the user after being decompressed by the pressure reducing valve. The evaporator 2 is a tubular structure...

Abstract

The invention discloses a method for storing and gasifying liquefied chlorine gas and complete equipments thereof in an electrolytic magnesium factory. The method is as follows: liquefied chlorine gas is loaded into a liquefied chlorine gas storage vat (1) and pressed into an evaporator (2) by depending on the pressure in the vat; hot water in a hot water vat (5) is sent into the evaporator (2) for heating; chlorine gas comes out from the top of the evaporator, sequentially goes into a buffer tank (3), a distributor device (4), decompressed by a reducing valve, and then sent to users. The device is characterized in that the liquefied chlorine gas storage vat (1) is connected with the evaporator (2) which is connected with the buffer tank (3); the buffer tank (3) is connected with the distributor device (4); the hot water vat (5) is connected with the evaporator (2). The liquefied chlorine gas storage vat (1) is put in a basement. The top of the basement is covered by heat insulator. In the invention, the high capacity liquefied chlorine gas storage vat is selected, used, and be put in the basement, which has little temperature variation and can guarantee safety; the liquefied chlorine gas evaporator is used and heated by hot water with better steady temperature; the generated chlorine gas has stable pressure, thus avoiding that accidents happen because of hypertension pressure.

Description

technical field [0001] The invention relates to a method for storing and gasifying liquid chlorine in an electrolytic magnesium plant and a complete set thereof. Background technique [0002] Magnesite is chlorinated and electrolytically smelted or magnesium oxide is formed into pellets. Chlorine is lost in the production process and needs to be supplemented by liquid chlorine. The factory is equipped with a liquid chlorine storehouse to store liquid chlorine and gasify the liquid chlorine, and send chlorine gas to the chlorination workshop to chlorinate magnesite or magnesium oxide pellets to produce magnesium chloride. In the past, liquid chlorine cylinders with a capacity of 0.5-2t were purchased, and the cylinders were stacked on the floor of the storage without walls or half walls. When gasifying liquid chlorine, put the liquid chlorine steel cylinder into the water tank and spray hot water or pass steam into the water tank to vaporize the liquid chlorine in the steel ...
