Abstract
The utility model relates to a raffinate processing and recovering device for liquefied gas, which is mainly composed of a driving cylinder, a driven cylinder, two control valves, a stroke valve, a pressure meter, a filter, a support frame, etc. The driving cylinder and the driven cylinder are connected by mechanical means and do reciprocating movement together. The driving cylinder and one control valve are connected with an air source through a pipeline. The driven cylinder and the other control valve are connected with the filter of a liquefied gas cylinder and a raffinate storage container through a pipeline. The utility model completes the operation of processing raffinate and pumping the cylinder vacuum together and is a full pneumatic system. The utility model has the characteristics of small size, light weight, low cost, simple processing technology, fire prevention and explosion prevention. The utility model is especially suitable for processing and recovering gas and liquid mixed phase medium, such as the raffinate of liquefied gas, etc.
Description
The utility model belongs to the processing and the recovery field of gas-liquid mixed phase medium, particularly relates to the processing and the recovering device of raffinate in a kind of civil liquefied gas steel cylinder.
Raffinate is the component that can not gasify again in steel cylinder, can't do domestic fuel and use.The existence of raffinate not only causes certain economic loss to the user, and some user turns voluntarily and handles raffinate and cause that the explosive accident of catching fire is also of common occurrence; But, be again a kind of good industrial fuel therefore because the steam of raffinate forces down.At present, only there is a spot of large-scale liquefied gas station to have raffinate to handle and recovering device, this device at first utilizes the inflated with nitrogen device that nitrogen is flowed to air compressor, after air compressor makes nitrogen supercharging, be passed to again in the cylinder for liquefied gas, raffinate extruded and is transported in the raffinate storage container by nitrogen gas pressure; With vacuum pump the nitrogen in the steel cylinder is evacuated to the certain vacuum degree again, raffinate is handled with recovery operation and is just finished like this.For example Zibo City, Shandong Province Boshan District liquefied gas station has just adopted above-mentioned liquefied gas residue to handle and recovering device.This device is owing to need set up vacuum pump and inflated with nitrogen device separately, and floor space is big, the cost height, and complex treatment process is difficult for being accepted by most of liquefied gas station, so its application has been subjected to very big restriction.
It is a kind of cheap that the purpose of this utility model is to provide, and volume is little, and is in light weight, and treatment process is simple, and the raffinate that is easy to be accepted by all kinds (large, medium and small type) liquefied gas station is handled and recovering device.The utility model is realized in the following manner.
Liquefied gas residue is handled and recovering device, by airtight raffinate storage container, pipeline is formed, it is characterized in that: the utility model also has active cylinder, passive cylinder, two control valves, stroke valve, active cylinder and connects mechanically with passive cylinder, and make it together reciprocating on control valve by the stroke valve action; Active cylinder links to each other with compressed air gas source by pipeline with control valve, and passive cylinder links to each other with airtight raffinate storage container with cylinder for liquefied gas by pipeline with another control valve; Two chambeies in the passive cylinder are negative pressure (vacuum chamber) on one side, and another side is a malleation, and with the to-and-fro motion of active cylinder mutually alternately.Feature of the present utility model also is: the control valve that is connected with passive cylinder is the cut-off type combination brake switch and proporting, with the logic component that a control exhaust-valve emptying is arranged on the pipeline that cylinder for liquefied gas is connected.
Because the utility model adopts the compressed air source, and raffinate handled with vacuumizing in the lump finish, and saved inflated with nitrogen device and vacuum pump, so it is little, in light weight to have a volume, price is low, and treatment process is simple, the characteristics that are easy to promote the use of; Be a kind of full pneumatic system simultaneously, have anti-flamingly that explosion prevention function is specially adapted to the processing and the recovery of gas-liquid mixed phase media such as liquefied gas residue again.
Description of drawings, Fig. 1 are situation plan of the present utility model.
Below in conjunction with accompanying drawing the utility model is elaborated.
Liquefied gas residue is handled and recovering device is by active cylinder 1, passive cylinder 2, and cut-off type control valve 3, logic component 4, filter 5, exhaust-valve 6, pressure gauge 7, pipeline 8, stroke valve 9, support 10, sliding valve style control valve 14, fastening piece 11 grades are formed.Compressed air gas source is through pipeline 8, and sliding valve style control valve 14 enters active cylinder 1, and active cylinder 1 links into an integrated entity mechanically with passive cylinder 2, and reciprocating; To-and-fro motion is acted on the sliding valve style control valve 14 by stroke valve 9 and realizes.Raffinate in the cylinder for liquefied gas 12 is through filter 5, cut-off type control valve 3 sucks the negative cavity of passive cylinder 2, and the raffinate in the malleation chamber is through cut-off type control valve 3, and exhaust-valve 6 is transported in the airtight raffinate storage container 13, two chambeies of passive cylinder 2 alternately suck raffinate, extrude raffinate.When treating that pressure in the steel cylinder 12 are reduced to certain value (illustrating that raffinate exhausts), send signal by logic component 4 and make exhaust-valve 6 emptyings, at this moment can vacuumize, can improve the efficient that it vacuumizes again steel cylinder.
