Abstract
The utility model discloses a low temperature BOG retrieves compressor, including gas holder, buffer tank and compressor, the gas holder give vent to anger the end with the inlet end of buffer tank is connected, the buffer tank give vent to anger the end with compressor's inlet end is connected, the seal box is installed to the giving vent to anger to serve of compressor, the lower extreme of seal box is provided with the fluid -discharge tube, and its middle part is provided with the blast pipe. The utility model discloses a BOG gas heater has been saved, reduce cost, BOG gas do not empty the burning but recycle has reduced the dirt to the environment, the permanent magnet rotor has advantages of simple structure, stable performance, and long service lifetime.
Description
Technical field
The utility model relates to a kind of recovery compressor, particularly relates to a kind of low temperature BOG and reclaims compressor.
Background technique
Domestic LNG Liquefied natural gas is in the initial development stage, and liquefaction technology itself is not also very ripe, stable.Two kinds are mainly contained to the processing mode of low temperature BOG:
The BOG gas-heated of a, air temperature type heater or water-bath type heater (ambient temperature is use lower than-5 DEG C)-120 DEG C to about-160 DEG C is to normal temperature, and being then disposed to releases flare burns;
The BOG gas-heated of b, air temperature type heater or water-bath type heater (ambient temperature is use lower than-5 DEG C)-120 DEG C to about-160 DEG C, to normal temperature, recycles after increasing a BOG compressor compresses.
Problems existing, after air temperature type heater or water-bath type heater, makes the cold energy of the BOG gas of-120 DEG C to about-160 DEG C all waste like this.If carry out emptying burning, while environment, waste a large amount of energy, cause the problems such as liquefaction plant energy consumption is high.
Model utility content
The purpose of this utility model is just to provide a kind of low temperature BOG to reclaim compressor to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises gas holder, knock out drum and refrigeration compressor, the outlet side of described gas holder is connected with the inlet end of described knock out drum, the outlet side of described knock out drum is connected with the inlet end of described refrigeration compressor, the outlet side of described refrigeration compressor is provided with sealing case, the lower end of described sealing case is provided with liquid-discharging tube, is provided with outlet pipe in the middle part of it.
The utility model is preferred, and the inlet end of described knock out drum is connected with described gas holder by the first pneumatic tube, and the outlet side of described knock out drum is connected with the inlet end of described refrigeration compressor by the second pneumatic tube.
The utility model is preferred, and described knock out drum is provided with by-pass cock.
The beneficial effects of the utility model are:
The utility model, by eliminating BOG gas heater, reduces costs; BOG gas does not carry out emptying burning but recycles, and decreases the dirt to environment; The utility model has that structure is simple, stable performance and working life longer advantage.
Accompanying drawing explanation
Fig. 1 is the structural representation that a kind of low temperature BOG described in the utility model reclaims compressor.
In figure: 1-refrigeration compressor, 2-knock out drum, 3-second pneumatic tube, 4-sealing case, 5-outlet pipe, 6-first pneumatic tube, 7-gas holder.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1: the utility model comprises gas holder 7, knock out drum 2 and refrigeration compressor 1, the outlet side of gas holder 7 is connected with the inlet end of knock out drum 2, the outlet side of knock out drum 2 is connected with the inlet end of refrigeration compressor 1, the outlet side of refrigeration compressor 1 is provided with sealing case 4, outlet pipe 5 is provided with in the middle part of it, the inlet end of knock out drum 2 is connected with gas holder 7 by the first pneumatic tube 6, the outlet side of knock out drum 2 is connected with the inlet end of refrigeration compressor 1 by the second pneumatic tube 3, knock out drum 2 is provided with by-pass cock 8.
Those skilled in the art do not depart from essence of the present utility model and spirit, various deformation scheme can be had to realize the utility model, the foregoing is only the better feasible embodiment of the utility model, not thereby interest field of the present utility model is limited to, the equivalent structure change that all utilization the utility model specifications and accompanying drawing content are done, is all contained within interest field of the present utility model.
