Description
Technical field
The utility model relates to retracting device, particularly a kind of water tank type cryogenic liquid product cold energy reclamation device.
Background technology
The use of cryogenic liquid product is more and more wider.As liquid nitrogen becomes nitrogen after gasification, as protective gas; As liquid oxygen becomes gaseous state oxygen through gasification, for burning, steel-making, medical treatment; If liquid argon is after gasification, for welding, stainless steel production, monocrystalline silicon production; Liquefied natural gas LNG, after gasification, becomes gaseous natural gas.
At present, the gasifier that cryogenic liquid product gasification is used, is two kinds of empty bath formula and water bath type gasifiers.Empty bath formula vaporizer is exactly: cryogenic liquid product enters from the access pipeline of gasifier, through gasifier internal pipeline, flow, during, the aluminium of liquid cryogenic product on gasifier pipeline closes golden Broad-rice-noodles, carries out heat exchange with gasifier surrounding air.Liquid cryogenic product after heat exchange, becomes gaseous product, through the outlet of vaporizer, flows out, and supplies required user.
In throughout the year, air temperature variations is larger, and especially in winter, lower environment temperature has obviously reduced the efficiency of vaporizer.In order to overcome this unfavorable factor, just on vaporizer, spray hot water or normal-temperature water.Thereby produced water bath type vaporizer.Also the bucket formula water bath type vaporizer that has more complicated.
Bucket formula water bath type vaporizer is normally placed in drum vaporizer, adds water in drum.When cryogenic liquid product, enter after vaporizer, its cold has just been passed in the water in drum.The water yield in drum is generally limited, and when cryogenic liquid product flow is large, or when winter when large (namely cold input), the water in drum has the risk being solidified.
At present, in empty bath formula vaporizer and water bath type vaporizer use procedure, contained cold in cryogenic liquid product, or be directly discharged in air, or entered in water and drained.Cold is not recycled utilization.
Summary of the invention
The purpose of this utility model is to design a kind of water tank type cryogenic liquid product cold energy reclamation device, the cold of discharging in recyclable cryogenic liquid product vaporescence, be used for the water of cooling normal temperature, it is cooling that the water being cooled can be used for subscriber equipment, also can be used for the place that user has cooling water demand.Can reach and utilize the energy, reduce cost effectiveness (CE).
For achieving the above object, the technical solution of the utility model is:
Water tank type cryogenic liquid product cold energy reclamation device, it comprises, water tank type heat exchanger, it comprises a cooling water pond and places heat exchanger wherein; Heat exchanger be provided with connect cryogenic liquid product storage tank cryogenic liquid product inlet ductwork and stop valve, connect gas user's gaseous product export pipeline and stop valve; Inlet and outlet pipe and the corresponding stop valve that is connected to respectively cooling water user established in described cooling water pond; Temperature is taken into account transmitter, and thermometer is arranged at cooling water pond; Automatic regulating valve, is arranged on the pipeline between cryogenic liquid product storage tank and empty bath formula vaporizer; One controller, described transmitter and automatic regulating valve are electrically connected respectively controller.
The utility model has the advantage of:
1. reclaim empty put the cold of cryogenic liquid product, for user, utilize.
2. it is example that the user of take uses the amount of liquid nitrogen of 30 tons every day, if liquid nitrogen from-193 ℃ of re-heats to 0 ℃, cold per hour has 138KW, can make 11 tons of water, lowers the temperature 10 ℃.
3. equipment investment expense is little, even can utilize the existing pond of client.
4. simple to operate, operation maintenance is convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Referring to Fig. 1, water tank type cryogenic liquid product cold energy reclamation device of the present utility model, it comprises, water tank type heat exchanger 1, it comprises a cooling water pond 11 and places heat exchanger 12 wherein; Heat exchanger 12 is provided with cryogenic liquid product inlet ductwork 10 and stop valve 2, the gaseous product export pipeline 20 that meets gas user 400 and the stop valve 3 that connects cryogenic liquid product storage tank 100; Inlet and outlet pipe 30,40 and the corresponding stop valve 4,5 that is connected to respectively cooling water user 300 established in described cooling water pond 11; Thermometer 6 and transmitter 7, thermometer 6 is arranged at cooling water pond 11; Automatic regulating valve 8, is arranged on the pipeline between cryogenic liquid product storage tank 100 and empty bath formula vaporizer 200; One controller 9, described transmitter 7 and automatic regulating valve 8 are electrically connected respectively controller 9.
Cryogenic liquid product enters water tank type heat exchanger 1 from cryogenic liquid product storage tank 100 through cryogenic liquid product inlet ductwork 10, is heated after gasification, and normal temperature gaseous product enters pressure regulator valve group 500 through stop valve and gives gas user 400; Cooled cooling water is supplied with cooling water user 300 and is used under the effect of pump; Cooling water after use enters in cooling water pond through stop valve, then it is cooling to carry out heat exchange.
When thermometer detects in pond cooling water temperature and changes, automatic control system can be opened the automatic regulating valve on cryogenic liquid all-product line automatically, cryogenic liquid product section enters air-bathing gasifier, reduced the cryogenic liquid product that enters water tank type heat exchanger, in order to regulate water temperature, prevent icing phenomenon in pond.
