Submerged combustion gasification sled: high-temperature burner is directed to the injection pipe that is positioned at tube bank below, then by the aperture on injection pipe upper surface, becoming small bubble is immersed in the water, heat exchange unit has anfractuose pipe, what heat exchanging tube replaced obtains heat energy from external small bubble, then by LNG Liquefied natural gas heating and gasifying.This vaporizer consumes the combustion gas of self, and operating cost is high, and need to process waste water (PH, COD), and maintenance and operation is complicated.
Hot bath formula gasification sled: this vaporizer adopts tubular evaparator, is LNG Liquefied natural gas in pipe, and pipe is outer is warm water, medium flash evaporation, gasification after warm water heating in pipe, after pressure regulation, transmission & distribution are to outside ductwork, and this vaporizer need to provide thermal source, and operating cost is high.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of simple in structure, easy and simple to handle, air temperature type natural gas gasifying device that operating cost is low, applied widely.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of air temperature type natural gas gasifying device, comprise rock gas liquid inlet pipe, empty warm vaporizer, rock gas steam outlet pipe, entrance cryogenic globe valve is installed on rock gas liquid inlet pipe successively, inlet filter, inlet temperature table, inlet pressure table, the outlet of rock gas liquid inlet pipe is connected with the liquid inlet pipe of sky temperature vaporizer, the steam outlet pipe of empty warm vaporizer is connected with the entrance of rock gas steam outlet pipe, installation outlet pressure gauge successively on rock gas steam outlet pipe, outlet temperature table, outlet shutoff valve, safe exhaust stack in parallel on rock gas steam outlet pipe between outlet temperature table and outlet shutoff valve, root valve is installed on safe exhaust stack successively, safety valve, diffusion valve in parallel also between rock gas steam outlet pipe and safe exhaust stack.
The utility model air temperature type natural gas gasifying device, wherein said rock gas liquid inlet pipe connects entrance stainless steel metal flexible tube.
The utility model air temperature type natural gas gasifying device, wherein said rock gas steam outlet pipe connection outlet stainless steel metal flexible tube.
The utility model air temperature type natural gas gasifying device, wherein said entrance cryogenic globe valve adopts ultralow temperature Stainless Steel Valve.
The utility model air temperature type natural gas gasifying device, simple in structure, easy and simple to handle, without extra power and power consumption, utilize ambient air energy completely, operating cost is low, and energy saving is convenient to install, applied widely.
Below in conjunction with accompanying drawing, air temperature type natural gas gasifying device of the present utility model is described further.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model air temperature type natural gas gasifying device;
Fig. 2 is the structural representation of the utility model air temperature type natural gas gasifying device hollow temperature vaporizer.
Embodiment
As Fig. 1, shown in 2, the utility model air temperature type natural gas gasifying device comprises rock gas liquid inlet pipe 1, empty warm vaporizer 2, rock gas steam outlet pipe 3, entrance cryogenic globe valve 11 is installed on rock gas liquid inlet pipe 1 successively, inlet filter 12, inlet temperature table 13, inlet pressure table 14, the outlet of rock gas liquid inlet pipe 1 is connected with the liquid inlet pipe 23 of sky temperature vaporizer 2, the steam outlet pipe 24 of empty warm vaporizer 2 is connected with the entrance of rock gas steam outlet pipe 3, installation outlet pressure gauge 31 successively on rock gas steam outlet pipe 3, outlet temperature table 32, outlet shutoff valve 33, safe exhaust stack 4 in parallel on rock gas steam outlet pipe 3 between outlet temperature table 32 and outlet shutoff valve 33, on safe exhaust stack 4, root valve 41 is installed successively, safety valve 42, diffusion valve 5 in parallel also between rock gas steam outlet pipe 3 and safe exhaust stack 4.
