Utilize cryogenic liquid vaporization cold energy dry ice producer
The present invention relates to a kind of dry ice producer, particularly utilize the device of cryogenic liquid vaporization cold energy dry ice processed.
What the general employing of dry ice was made in industry is to obtain dry ice with the liquid carbon dioxide throttling expansion, and this technology dry ice production rate generally has only about 40%, and difficult recovery of the carbon dioxide that do not condense mostly caused very big waste; And if adopt freon refrigeration or ammonia refrigeration processing method to obtain that though the low temperature cold can improve the dry ice production rate but need bigger refrigeration compressor, consume more electric energy.
Usefulness low temperature storage tanks such as increasing various cryogenic liquid such as liquid oxygen, liquid argon, liquid nitrogen store, and then with the cryogenic liquid pump pressurization, take to charge into the gas cylinder sale after the empty bath formula vaporizer heat exchange vaporization.When filling operation, because the high pressure low temperature liquid behind the cryogenic liquid pump leans on the air heat exchange carburation by evaporation in vaporizer and the atmosphere, a large amount of cryogenic cold energy is lost in the atmosphere goes.For example, 1 cubic metre of liquid oxygen in the common storage tank from-160C through being gasificated into the cold energy that the normal temperature and pressure gaseous state can produce about 100,000 kilocalories, if consider variation and the influence of charge pressure, also can produce the cold energy of about 80,000 kilocalories, so big cryogenic cold energy recovery is produced dry ice and can be produced huge economy and environmental benefit.
Summary of the invention
In order to overcome the shortcoming of prior art, the invention provides a kind of cryogenic liquid vaporization cold energy dry ice producer that utilizes, it is that all kinds of cryogenic liquids are filled the cryogenic cold energy of gasification for the condensation cure of carbonic acid gas, need not to increase power consumption, the dry ice production rate can reach 100% in theory, is an energy-conserving and environment-protective new technology of producing dry ice.
The present invention solves the technical scheme that its technical problem takes: liquor pump one end communicates with the low temperature storage tank sealing by pipeline, the other end communicates with the end sealing of vaporizer by pipeline, valve, the other end of vaporizer communicates to seal with the collision system sealing by pipeline and communicates, the two ends of described valve by pipeline, valve and dry ice producer interchanger and connect, the carbon dioxide import of dry ice producer communicates with the dioxide bottle sealing.
1), can utilize the cold energy that produces of vaporizing in the liquid filling process to realize the energy-conservation dry ice processed of no consumption the present invention has following advantage:.Greatly reduce than original dry ice function consumption processed; 2), can not destroy the normal operation of former charging system, and can reduce the heat exchange load of original vaporizer; 3), the cold energy of dry ice processed can regulate by variable valve, and temperature can realize automatic control; 4), present technique is applicable to continuously or a bottle production process is filled in the cryogenic liquid that fills continuously in for some time vaporization, does not also influence original charging system work even do not produce dry ice, for enterprise of liquid fueling station increases a coproduction dry ice project.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is synoptic diagram of the present invention.
As shown in Figure 1, liquor pump 2 one ends communicate with low temperature storage tank 1 sealing by pipeline, the other end communicates with the end sealing of vaporizer 5 by pipeline, valve 4, the other end of vaporizer 5 seals the sealing that communicates by pipeline with collision system 12 and communicates, the two ends of described valve 4 by pipeline, valve 3 and dry ice producer interchanger and connect, the carbon dioxide import of dry ice producer communicates with dioxide bottle 11 sealings, and dioxide bottle 11 also can be the carbonic acid gas storage tank.
Described dry ice producer comprises insulating shell 9, interchanger 7, inner bag 8, piston 6 and dry ice shape switchboard 10, piston 6 is in stainless inner bag 8, be slidingly matched with inner bag 8, one end of inner bag 8 is dry ice shape switchboard 10 fixedly, twine the interchanger 7 of copper pipe formula on the cylindrical surface of inner bag 8, interchanger 7 external parcel insulating shells 9 prevent cold draining; On the described inner bag 8 the carbon dioxide import is arranged.
A plurality of dry ice hole is arranged on the end face of described dry ice shape switchboard 10, and dry ice hole cross section is circle or sheet shape, or other shapes, to satisfy the needs of different user.
During use, according to the aperture of how much coming regulated valve 4 of institute's chilling requirement.Cryogenic liquid with the heat exchange of dry ice producer after return original high-pressure carburetor piping system again, do not influence the vaporization of original high pressure charging system and fill, can also reduce the working load of former vaporizer.
