The purpose of this utility model is the process units of a kind of industrial cutting gas of design, and this Cutting Gas can substitute acetylene gas, and performance is better.
The technological scheme that realizes above-mentioned purpose is, this industrial cutting gas process units mainly is made up of pressurized tank, circulation loop, additive displacement apparatus three parts, pressurized tank 2 adopts liquified gas container, relief valve port a connects safety valve 3, sewage draining exit d connects raffinate pipe 17, gas phase mouth e connects basin gas phase pipe 19, and liquid entering hole b, liquid outlet c link to each other with circulation loop; Circulation loop 5 is by valve, hydrocarbon pump 15, and liquid entering hole b, liquid outlet c constitute, and are connected with the liquid inlet pipe 13 from liquified gas container in circulation loop, are connected with the output tube 14 of industrial cutting gas, and are connected with the additive displacement apparatus.The additive displacement apparatus is that additive displacement tank 9 is provided with two exhaust- valves 7,8, the lower end of displacement tank 9 is provided with feed inlet and outlet 21, feed inlet and outlet connects valve 10,11, between two valves 10,11, be connected with flange plate, make that displacement tank and circulation loop are detachable the connection, valve 11 links to each other with circulation loop.
This apparatus structure is simple, and is easy to operate, and Security is good, and the industrial cutting gas of being produced has that Security is good, and cut quality is good, and otch is smooth, than advantage such as the cost of production of acetylene gas is low.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of additive displacement dress.
As shown in Figure 1, pressurized tank 2 adopts known liquified gas container, and it has 5 import and export usually, also has liquid level meter 1, thermometer 20, hand-hole 4, jar bearing 18 etc.Relief valve port a connects safety valve 3, and gas phase mouth e connects the gas phase pipe 19 of liquefied gas station basin, and sewage draining exit d connects raffinate pipe 17, and liquid entering hole b and liquid outlet c are connected in the circulation loop.Need to prove that this device should be installed in liquefied gas station, the industrial cutting gas of making becomes bottle in the liquefied gas station can, is transported to on-the-spot the use again.
The annexation of circulation loop 5 is: the liquid outlet c of pressurized tank 2 connects valve 16, hydrocarbon pump 15, valve 6, links to each other with the liquid entering hole b of pressurized tank to constitute a loop again; Between hydrocarbon pump 15 and valve 6, also be connected with liquid gas liquid inlet pipe 13, industrial cutting gas output tube 14 and additive displacement apparatus.
The additive displacement apparatus as shown in Figure 2, for additive is fully mixed with liquid gas, additive displacement tank 9 is oval pressurized tank, and also is provided with exhaust-valve 7, exhaust-valve 8 to discharge residual gas and the air that remains in when this device is stopped using in the displacement tank on this displacement tank.The displacement tank lower end is a feed inlet and outlet 21, and flange plate 22 is fixed on the feed inlet and outlet, and valve 10 links to each other with feed inlet and outlet by flange plate, and 12 is flange among the figure.
Working principle of the present utility model is: one, pressurized tank receives liquid gas

3, open hydrocarbon pump 15, valve 16, beginning is injected liquid gas (observing the liquid level meter) till satisfy yielding capacity in pressurized tank, and throttle down 13,19 then, being communicated with of the gas, liquid of cut-out pressure jar and gas tank.Two, the production of industrial cutting gas
1, throttle down 7,8,10,11, and the flange plate between the valve 10,11 is unscrewed, and pull down additive displacement tank 9.Displacement tank 9 is shifted out the gas station to place of safety, open valve 7,8,10, bleed off a jar interior residual gas.
2, additive is added in the jar 9 by valve 10, throttle down 10 is opened valve 7,8, and nitrogen is charged in the jar by valve 7, adopts the nitrogen replacement method that air in the jar and small amount of residual Cutting Gas are got rid of by valve 8.
3, displacement tank 9 is installed on the valve 11.
4, Open valve 6,16, start hydrocarbon pump 15, and liquid gas is circulated in pipeline;
5, Open valve 10,11, and additive is communicated with circulation loop;
6, in liquid gas was circulated throughout kind, the additive in the displacement tank was replaced to liquid gas, after circulation a period of time, throttle down 10,11, finish Cutting Gas production, wait to irritate jar.Three, can
