Description
Technical field
The utility model relates to the gasification installations of LPG and LNG, especially a kind of that there is LPG forced gasification and LNG to force gas
Change LPG, LNG double-purpose gasification installation of function.
Background technique
With the variation of China's energy resource structure and continuing to increase for environmentally friendly dynamics, obtain the development and utilization of natural gas fast
Violent development, temperature of the liquefied natural gas after air temperature gasifier gasification changes with variation of ambient temperature, especially in the winter
In season, vaporization ability decline is obvious, can use the forced gasification device of LNG；Due to gas source is nervous, LNG (liquefaction in winter
Natural gas) price float it is larger, can be considerably beyond LPG (liquefied petroleum gas), such LPG has a very big advantage, but individually on
Two sets of gasification installations not only increase cost, and occupied area also will increase, it is therefore desirable to provide using set of device, realize that two are arranged
Standby function.Moreover, gas, which occurs, in its gas outlet tube Louis of existing gasification installation returns to liquid situation, gas gasification is influenced
Effect.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of LPG, LNG double-purpose gasification installation, energy
Enough it is suitable for the gasification function of LPG, LNG gas, while gas is avoided to return to liquid.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of LPG, LNG double-purpose gasification installation, it is characterised in that: including gasifier, the inlet connection LPG of gasifier,
LNG shares inlet pipe, shares in LPG, LNG and installs inlet stop valve in inlet pipe；LPG, LNG share inlet pipe and connect
Gasifier internal heat coil pipe is connect, heat exchange coil is connected to the gas exit line of gasifier, and pressure is arranged on gas outlet tube road
Power table, safety valve, liquid-level switch, thermometer and temperature sensor, gasifier are internally provided with anti-explosion electric heater, on gasifier
Portion connects filler, and discharge outlet is arranged in gasifier bottom, and the temperature sensor is connected to controller, and controller connects inlet
Stop valve, control inlet stop valve stops feed liquor when the gas temperature detection signal of gas exit line is lower than condensing temperature.
Moreover, inverse inhalation type sewage draining exit is arranged in the gasifier top, which connects sewage pipe, the sewage pipe
Stretch to the bottom in gasifier.
It the advantages of the utility model and has the beneficial effect that
1, LPG, LNG double-purpose gasification installation of the utility model shares inlet pipe by setting LPG, LNG, realizes
Heat exchanger tube heat exchange amount is rationally arranged according to LPG, LNG gasification demand in LPG, LNG double-purpose functional, meanwhile, inlet pipe and gas
Export pipeline is all made of stainless steel material to prevent liquid corrosion；Meanwhile temperature sensor, root are set on gas outlet tube road
Judge whether gas returns to liquid according to gas outlet temperature and pressure, need to ensure that air outlet temperature is higher than 40 according to existing pressure
DEG C, when be lower than 40 DEG C when then judge its for return liquid, and control inlet stop valve stopping feed flow.
2, inverse inhalation type sewage draining exit, the inverse inhalation type is arranged in LPG, LNG double-purpose gasification installation of the utility model, gasifier top
Sewage draining exit connects sewage pipe, which stretches to the bottom in gasifier, realizes inverse inhalation type dirt eliminating function, improves gasification installation
Operational efficiency.
3, LPG, LNG double-purpose gasification installation of the utility model, scientific structure design is reasonable, is suitable for LPG, LNG gas
Gasification function, while avoid gas return liquid, guarantee the gasification result of gasification installation.
Detailed description of the invention
Fig. 1 is the system flow chart of the utility model.
In figure: 1- gasifier, 2-LPG, LNG share inlet pipe, 3- heat exchange coil, 4- gas exit line, 5- liquid level
Meter, 6- anti-explosion electric heater, the filler 7-, 8- discharge outlet, 9- exhaust outlet, 10- temperature sensor, 11- liquid-level switch, 12- into
Liquid mouth stop valve, 13- pressure gauge, 14- safety valve, 15- thermometer, 16- blowdown valve.
Specific embodiment
Below by specific embodiment, the utility model is described in further detail, following embodiment be it is descriptive, no
It is restrictive, protection scope of this utility model cannot be limited by this.
A kind of LPG, LNG double-purpose gasification installation comprising gasifier 1, gasifier inlet connection LPG, LNG share into
Liquid pipeline 2 shares in LPG, LNG and installs inlet stop valve 12 in inlet pipe；LPG, LNG share inlet pipe connection gasification
Device internal heat coil pipe 3, heat exchange coil are connected to the gas exit line 4 of gasifier, pressure gauge are arranged on gas outlet tube road
13, safety valve 14, liquid-level switch 11, thermometer 15 and temperature sensor 10, gasifier are internally provided with anti-explosion electric heater 6,
Gasifier top connects filler 7, and discharge outlet 8 is arranged in gasifier bottom, and temperature sensor is connected to controller, controller connection
Inlet stop valve, control inlet stop valve stops when the gas temperature detection signal of gas exit line is lower than condensing temperature
Feed liquor.Inverse inhalation type sewage draining exit is arranged in gasifier top, and simultaneously blowdown valve 16, the blowdown is arranged in inverse inhalation type sewage draining exit connection sewage pipe
