If the ratio of hydrogen and chlorine is not adjusted properly, hydrogen chloride will contain incompletely combusted chlorine gas (referred to as "overchlorine"), which will be sent to the vinyl chloride synthesis unit together with hydrogen chloride gas. When the concentration of chlorine gas exceeds a certain When the value is high, excessive free chlorine can react violently with acetylene, which synthesizes vinyl chloride, causing vicious accidents such as combustion and explosion, and posing a great safety threat to production work
When overchlorination occurs in the existing hydrogen chloride synthesis furnace, the operator usually cannot make effective adjustments in a short period of time, and cannot control the overchlorination of hydrogen chloride gas in time, so that the occurrence of the above-mentioned vicious accidents cannot be avoided

Embodiment Construction
[0021] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but should not be used to limit the scope of the present invention.
[0022] Such as figure 1 As shown, the interlock signal system for placing hydrogen chloride gas perchlorination in this embodiment includes a pressure sensor 1, a hydrogen control valve, a chlorine control valve, an air supply valve 6, an acid valve 7 and a control system. Pressure sensor 1 is arranged on the hydrogen gas intake pipe of hydrogen chloride synthesis furnace 8, and is used to detect the hydrogen pressure in the hydrogen gas intake pipe; 4. The hydrogen regulating valve 2 is used to adjust the intake amount of hydrogen, and the hydrogen shut-off valve 4 is used to cut off or open the hydrogen intake pipe. The position of the hydrogen shut-off valve 4 is closer to that of the hydrogen...

The invention relates to the technical field of the chlor-alkali production, and concretely discloses an interlock signal system for preventing the perchlorination of a hydrogen chloride gas, and a method thereof. The system comprises a pressure sensor, hydrogen control valves, chlorine control valves, a gas feeding valve, an acid valve and a control system. The method comprises the following steps: presetting a pressure interlock value of hydrogen, detecting the pressure of hydrogen through the pressure sensor, and controlling the opening and closing of all above valves according to the detected hydrogen pressure. The system and the method have the advantages of prevention of the generation of incompletely combusted chlorine in the hydrogen chloride gas synthesis process, timely control of the perchlorination of the hydrogen chloride gas, avoiding of the malignant accidents of combustion and explosion caused by the reaction of excess free chlorine in hydrogen chloride and acetylene for synthesizing vinyl chloride, protection on a hydrogen chloride synthesis furnace and subsequent apparatuses, labor force reduction, personnel optimization, system safety guarantee, and stable and continuous production.
Description
technical field [0001] The invention relates to the field of chlor-alkali production technology, in particular to an interlock signal system and method for preventing hydrogen chloride gas from overchlorinating when hydrogen chloride is synthesized. Background technique [0002] In the production process, the combustion of hydrogen and chlorine in the synthesis furnace to generate hydrogen chloride is an extremely critical production link. If the ratio of hydrogen and chlorine is not adjusted properly, hydrogen chloride will contain incompletely combusted chlorine gas (referred to as "overchlorine"), which will be sent to the vinyl chloride synthesis unit together with hydrogen chloride gas. When the concentration of chlorine gas exceeds a certain When the value is high, excessive free chlorine can react violently with acetylene, which synthesizes vinyl chloride, causing vicious accidents such as combustion and explosion, and posing a great safety threat to production work. ...
