Description
Affiliated technical field
The utility model relates to the gasifying liquefied petroleum gas technical field, especially a kind of gasifying liquefied petroleum gas device that utilizes the heating of air pump low-pressure air.
Background technology
Gasifying liquefied petroleum gas will absorb a large amount of heat energy.In the place of the big flow of needs,, generally all adopt heating forced gasification technology such as civil pipeline central gas supply station, industrial enterprise's gasification station etc.Conventional gasifier has three kinds of electrical heating type hot bath formula and steam heated formulas.But it all will consume a large amount of artificial heat energy without exception, increases high operating cost.Though air-heating type gasifier and I reduce than above-mentioned three kinds of energy-dissipating type gasifier operating costs greatly at the natural energy gasifier of first to file, it is bulky, the manufacturing cost costliness.Utility model ZL200420074609.5 provides a kind of waste heat gasifier, because of it lacks the nature endotherm section and has only an evaporimeter, so when gasification decompression, the coldest medium did not have still that heat absorption just directly enters tank body through buffering, caused the output temperature of gas phase to reduce, and had influenced gasification result.
Summary of the invention
In order to overcome above-mentioned energy-dissipating type gasifier, air-heating type gasifier and the described shortcoming of waste heat gasifier, the utility model provides a kind of gasifying liquefied petroleum gas device that utilizes the heating of air pump low-pressure air, utilizes the air pump frictional heat just can freely finish the purpose of gasification to reach at the industrial enterprise's gasification station with air pump air feeding technique.
The technical scheme that its technical problem that solves the utility model adopts is: described a kind of gasifying liquefied petroleum gas device that utilizes the heating of air pump low-pressure air has the twin-stage heat-exchange system that last air duct and following air duct are connected.Its air duct is the metal low pressure vessel, built-in liquefied gas evaporimeter.Following air duct evaporimeter and natural endotherm section, liquid phase depressurized system, liquid phase import strainer valve are linked in sequence, and last air duct evaporimeter and gas phase breeze way, gas phase delivery outlet are linked in sequence.
Described natural endotherm section and gas phase breeze way are made up of the aluminium alloy sleeve pipe of multitube parallel.The outer tube exterior of heavy caliber is radial, and small-bore interior pipe hollow is installed explosion-proof ribbon heater, is liquid petroleum gas system in the interlayer of its two pipe.
Described a kind of gasifying liquefied petroleum gas device that utilizes the heating of air pump low-pressure air, liquid level gauge is established in the gas phase breeze way front of liquid petroleum gas system, and system's end is established safety valve, and blowoff valve is established in the bottom.The cascaded structure of integral device forms by cutting off the blind plate welding.
Described a kind of gasifying liquefied petroleum gas device that utilizes the heating of air pump low-pressure air, side of air duct is established the import of air pump low-pressure air respectively about it, and opposite side is established the outlet of air pump low-pressure air respectively, and the air duct bottom is established the condensed water draining valve respectively.
Because adopt technical scheme as above, the beneficial effects of the utility model are: allly all can utilize the air pump frictional heat of self freely to finish gasification at industrial enterprise's gasification station that air pump is arranged.Under the condition of work, the liquid phase liquefied gas is through depressurized system gasification cooling, at first entering nature endotherm section absorption air latent heat tentatively heats up, enter down afterwards air duct and in evaporimeter, carry out the secondary heat exchange with low-pressure air, enter air duct evaporimeter and low-pressure air again and carry out heat exchange for the third time, until finishing gasification.If still can not reach desirable gasification result, liquid phase will enter the gas phase breeze way, and at this moment, liquid level gauge will show liquid level, thereby the prompting administrative staff open and to be arranged in the gas phase breeze way that the ribbon heater in the pipe is auxiliary finishes gasification.
