The oxygen that water decomposition in the asbestos-free diaphragm electrolytic cell produces and hydrogen separately through the peroxide separator with after the hydrogen separator separates alkali lye, output to mixed combustion in external firing equipment such as the welding gun by pipeline.The ratio of Blang's gas because hydrogen that produces and oxygen proportion fit like a glove, the temperature of its combustion flame is very high.And the product behind hydrogen and the oxygen combustion is a water, compliance with environmental protection requirements.Simultaneously, the asbestos-free diaphragm electrolytic cell adopts asbestos-free diaphragm, has further satisfied environmental requirement.
Install spark arrester additional on oxygen delivery pipeline and the hydrogen delivery tube road, can avoid the gas that burns externally combustion apparatus close not at that time gas mutually string cause danger.
Oxygen self-supporting control valve can detect the hydrogen lateral pressure, thereby the gas output of correspondingly regulating oxygen reaches the purpose of controlled pressure balance; In the same manner, hydrogen self-supporting control valve can detect the oxygen lateral pressure, thereby the gas output of correspondingly regulating hydrogen reaches pressure balanced purpose, thereby makes hydrogen and oxygen proportion remain on the ratio of Blang's gas in real time.
Circulating reflux is in the asbestos-free diaphragm electrolytic cell automatically for alkali lye in oxygen separator and the hydrogen separator, and the water in the alkali lye can continue to be utilized by electrolysis.When the alkali lye in the asbestos-free diaphragm electrolytic cell reaches finite concentration, can it be discharged from sewage draining exit by the alkali lye outlet of asbestos-free diaphragm electrolytic cell.
Fin is that the mode that adopts air to cool off is naturally cooled off built-in system; Fan then is to adopt external impetus to force the mode of cooling that built-in system is cooled off.Above-mentioned two kinds of types of cooling can be used in combination the built-in system of cooling water welding machine.
Water replanishing device carries out moisturizing in the oxygen separator, the water that enters the oxygen separator flows in the asbestos-free diaphragm electrolytic cell with alkali lye, thus the final purpose that realizes moisturizing in the asbestos-free diaphragm electrolytic cell.Before moisturizing in the oxygen separator, with the valve closing between the water supplement port of moisturizing intermediate receptacle and oxygen separator, valve closing between the gas outlet of moisturizing intermediate receptacle and oxygen separator, valve open between moisturizing intermediate receptacle and the water source, valve open between moisturizing intermediate receptacle and the oxygen emptying mouth, because moisturizing this moment intermediate receptacle internal gas pressure is identical with external atmosphere pressure, and the pipeline connection between moisturizing intermediate receptacle and the water source, so the water source can water filling in the moisturizing intermediate receptacle, thereby finish process to the retaining of moisturizing intermediate receptacle.When needs in the oxygen separator during moisturizing, with the valve open between the water supplement port of moisturizing intermediate receptacle and oxygen separator, valve open between the gas outlet of moisturizing intermediate receptacle and oxygen separator, valve closing between moisturizing intermediate receptacle and the water source, valve closing between moisturizing intermediate receptacle and the oxygen emptying mouth, this moment, the pressure of moisturizing intermediate receptacle and oxygen separator reached balance, water under the effect of liquid level difference in the moisturizing intermediate receptacle flows in the oxygen separator, has realized utilizing the unpowered moisturizing in the oxygen separator of internal system pressure-exchange and liquid level difference.
Because at the moisturizing intermediate receptacle be arranged on pipeline and the oxygen spark arrester between the oxygen emptying mouth on the housing and be arranged on another pipeline and the valve that connects on the pipeline between the oxygen outlet on the housing, so the amount that can regulate oxygen is to regulate ignition temperature, unnecessary oxygen is then by drain emptying.
