Description
Technical field
The present invention relates to a kind of method that the cold water latent heat of solidification is produced fluid ice of extracting, be specifically related to a kind of method of producing fluid ice based on wall strain stripping ice extraction latent heat of solidification.
Background technology
Why latent heat of solidification type heat pump is applied, first China has the surface water resources of huge amount, these surface water can provide sufficient low level heat energy for latent heat of solidification type heat pump, but winter, the water of river, lake and sea water temperature was very low, minimum about 2～4 ℃, therefore utilizable sensible heat energy space is very limited, but also there is the danger of frozen blocking pipe and equipment, the latent heat of solidification of only taking new technology and method to extract the part water yield could satisfy the requirement of engineering load, also can avoid equipment failure simultaneously; Its two be the development of present urban sewage source heat pump rapidly, but studies show that, even maximum utilize the sewage sensible heat, do not satisfy every yet and build needed thermic load requirement.For the sewage effluent heat energy supply that guarantees every building can be self-sufficient, just must extract 5～15% the latent heat of solidification that is contained in the sewage.The method of extracting at present latent heat of solidification and obtain fluid ice from water mainly contains two classes, one class is the water generation " unrooted ice " of condensing in subcooled water or immiscible cryogenic liquid, and then ice liquid and separate, this class technology still is in the laboratory research stage at home and abroad; Another kind of is the water generation " have root ice " of condensing on the low temperature wall, then with peeling off ice crystal from wall someway, allows water take away again.Traditional ice crystal stripping means adopts mechanical means, promptly utilize mechanical scraper plate kind equipment to peel off ice crystal, and be mainly used in closed cycle ice makings such as seawater, hard grind between mechanical surface is wiped and is required the apparatus processing precise, bulky, pernicious working environment greatly reduces the service life of equipment, has also increased the transmission energy consumption simultaneously.
Summary of the invention
The objective of the invention is from various water sources, to extract latent heat of solidification and produce fluid ice for solution, adopt mechanical means to peel off fluid ice, have that the device therefor investment is big, volume is big, service life equipment is low, the big problem of transmission energy consumption and provide a kind ofly extract the method that latent heat of solidification is produced fluid ice based on wall strain stripping ice.Method of the present invention is finished by following steps: a, water pass to the low-temperature heat exchange carrier with the latent heat of solidification amount in the water through on the elastic deformable body wall time, make the water of release heat form ice sheet on the elastic deformable body wall; B, the elastic deformable body wall is applied external force, elastic deformable body wall generation strain, the ice sheet be full of cracks that the elastic deformable body wall is formed; The ice crystal of c, be full of cracks is peeled off from the elastic deformable body wall under current, air-flow or gravity effect; D, the ice crystal that strips down are along with current flow away together, and elastic deformable body returns to the original form.
The present invention has following beneficial effect: one, the present invention becomes ice sheet with water on low temperature elasticity deformable body wall, the shear stress that utilizes the elastic deformable body wall to produce, make ice sheet be full of cracks and peel off, thereby do not have hard grind wiping and mechanical damage problem, energy consumption is low, the life-span is long.Two, utilize the souring and the flowability of fluid ice, make the ice sheet of be full of cracks break away from wall fully and taken away, therefore be specially adapted to system's of circulating (open and closed all can) by circulating water.Three can be applied to this ice making method so long as can produce the wall of strain, and the direct contact heat-exchanging (being that the heat exchange carrier is an air) of heat exchange carrier and fluid ice, also can separate indirect heat exchange (being that the heat exchange carrier is a cryogenic fluid) by the elastic deformable body wall, therefore this ice making method has multiple application form, flexible, can be different because of need.Four, this ice making method is few, widely applicable to the kind and the water quality requirement restriction of water, is not only applicable to seawater, also applicable to running water, water of river and lake, perhaps only contains the municipal sewage of small size foreign material.Five, this ice making method is of many uses, and not only being used for the heat supply is the latent heat of solidification type heat pump of purpose, and also can be used for simple is in food refrigerated, the ice storage air conditioner of purpose, also to can be used in the energy conserving system of above the two combination simultaneously with the ice making.Six, with the water that flows ice crystal is taken away, deposition is not coalescent in transportation can to guarantee ice crystal.Seven, fluid ice its freeze and the process of melting in have phase transformation and have higher cooling capacity and heat exchange efficiency, the latent heat of solidification of 1kg clear water is about 80 times (latent heat of solidification of 1kg clear water is 335kJ/kg) of every degree centigrade of sensible heat; Ice content is when to be 5～30% fluid ice as the media of fluid interchange contact with the elastic solid (Hookean body) wall, and its coefficient of heat transfer is at 3000W/ (m
2K) about; Fluid ice has good flowability in addition, can transport with pump.Eight, the present invention have that simple to operate, easy enforcement, heat transfer efficiency height, energy consumption are low, Monitoring and Controlling advantage easily.
