Problems solved by technology
The circulating heating of hot water requires a set of instrument control system, which complicates the gasification process of liquid chlorine
If the operation is not careful, there are safety hazards
[0006] (3) "Hot water gasification method" only has the function of gasifying liquid chlorine, and does not have the function of heating and superheating chlorine gas
This also complicates the "hot water gasification" liquid chlorine gasification process

The invention relates to a liquid chlorine gasifying system. The technical scheme is as follows: the liquid chlorine gasifying system is formed by a liquid chlorine gasifying part, a water steam heating part and a chlorine gas buffering part; the liquid chlorine gasifying part is characterized in that a liquid chlorine inlet of a gasifying device is connected with a liquid level adjusting valve; a pipeline between a chlorine gas outlet and a buffering tank is provided with a temperature measuring meter and a pressure measuring meter; the temperature measuring meter and the pressure measuring meter are connected in series, and a liquid level measuring meter is connected with a liquid level meter opening and the liquid level adjusting valve respectively; and a chlorine gas leakage detection alarming instrument is arranged outside the gasifying device. The water steam heating part is characterized in that a water steam inlet is connected with a pressure adjusting valve, and a condensed water outlet is sequentially connected with a condensed water steam trap and an acidic degree analyzer; and the pressure adjusting valve is connected with the pressure measuring meter. The chlorine gas buffering part is characterized in that a flow adjusting valve and a flow meter are sequentially arranged on a chlorine gas outlet pipeline of the buffering tank; a leaking valve is arranged on a pipeline between the buffering tank and the flow adjusting valve; and the leaking valve is connected with the pressure measuring meter. The liquid chlorine gasifying system has the advantages of stability in production and operation, safety and reliability, high gasification efficiency and heat transferring efficiency, and low energy consumption.
Description
technical field [0001] The invention belongs to the field of chlorine gas production, and in particular relates to a chlorine gas production system which adopts saturated water vapor to indirectly heat liquid chlorine to obtain high purity and high safety. Background technique [0002] Chlorine gas is an inorganic chemical product, which is obtained by electrolysis of table salt. It is widely used in pesticides, medicine, papermaking, organic chemical industry, inorganic chemical industry, fine chemical industry and other industries and fields. Many industries that use chlorine gas as chemical raw materials or chemicals are sensitive to chlorine gas. The purity requirement is very high, and the purity of chlorine gas obtained by liquid chlorine gasification is high. Especially those factories that do not produce chlorine gas but need chlorine gas, mostly adopt the method of gasifying liquid chlorine to obtain chlorine gas. [0003] In the prior art, the gasification of liq...
