Technical Field

[0001] The utility model relates to the technical field of liquid chlorine storage, in particular to a liquid chlorine storage device for methane chloride production. Background Art

[0002] Methane chloride, also known as chloromethane, is a product in which hydrogen atoms in methane molecules are replaced by chlorine atoms. It is an important basic organic chemical raw material and an excellent organic solvent, and is widely used in organosilicon, organofluorine, foaming agent, methyl cellulose and its derivatives. With the expansion and development of its application range, methane chloride plays an increasingly important role in the national economy. Chlorine is an important component in the production process of methane chloride, so the storage of liquid chlorine is crucial in the production process of methane chloride. To facilitate the storage and transportation of chlorine, chlorine is generally liquefied into liquid chlorine and stored in liquid chlorine storage tanks.

[0003] However, most of the liquid chlorine storage tanks in the prior art do not have an antifreeze structure. When the ambient temperature is low, the liquid chlorine in the storage tank is easily frozen. The frozen liquid chlorine cannot be effectively vaporized, which will reduce the chlorine supply capacity of the liquid chlorine storage tank, seriously restrict the production efficiency of methane chloride, and reduce the practicality of the device. In view of this, the present application proposes a liquid chlorine storage device for methane chloride production. Utility Model Content

[0004] In response to the deficiencies in the prior art, the utility model provides a liquid chlorine storage device for methane chloride production, which has the function of preventing liquid chlorine from freezing and maintaining the chlorine supply capacity of the storage tank. It can also detect and control the storage environment of the storage tank in real time, making the management of the storage tank more convenient. It solves the problem that most liquid chlorine storage tanks in the prior art do not have an antifreeze structure, which easily causes the liquid chlorine in the storage tank to freeze when the ambient temperature is low, thereby reducing the chlorine supply capacity of the liquid chlorine storage tank, seriously restricting the production efficiency of methane chloride, and having poor practicality.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a liquid chlorine storage device for methane chloride production, comprising a storage tank body, wherein the storage tank body is composed of a cylinder and heads located at both ends of the cylinder, an antifreeze treatment mechanism is provided inside the storage tank body, and a monitoring auxiliary component is provided inside the storage tank body;

[0009] Furthermore, the bottom of the cylinder is fixedly connected with a liquid chlorine outlet, and the top of the cylinder is fixedly connected with a gas phase port and a safety valve port.
