Abstract
The present invention belongs to a method for improving the breeding process flow of aquatic products, particularly to a method for improving the breeding process flow of kelps. Problems to be solved are that the refrigeration equipment of a background art is lag, civil construction investment is high, the hidden trouble of ammonia gas leakage exists, energy resource waste is serious, a large quantity of energy resources are wasted because hundreds of tons of low-temperature sea water are discharged, a water changing effect is not ideal, and water quality can not be thoroughly ameliorated. The technical scheme gist adopted to solve the technical problems is that an evaporator A of a refrigeration system and an evaporator B of the refrigeration system are ammonia division plate changing chilling units. Before one part of a breeding pond is discharged through a waste water recovering pond, the part exchanges heat with partial sea water from a water storing pond through a titanium plate type heat exchanger and is discharged. The part after the heat is exchanged is from the water storing pond, one part of the sea water flows to the water recovering pond, and the other part flows to the evaporator A of a refrigeration system. The method can be widely used for improving the breeding process flow of the existing kelps and has the advantages of good refrigeration effect, no ammonia leakage danger, energy saving and thorough water change.
Description
Technical field: the invention belongs to improving one's methods of a kind of aquatic fry growing technological process, the improving one's methods of particularly a kind of kelp seedling cultivation technological process.
Background technology: the technological process of existing sea-tangle natural daylight cryogenic flow rice seedling on watered bed is to found nineteen sixties, continued to use 40 so far surplus year.In practice for many years, the factory of respectively growing seedlings has carried out some improvement to technological process.Development along with relevant industries, various new technology and equipments are born in succession, and this technological process exposes following shortcoming: the one, and refrigeration plant falls behind, and the evaporator in the refrigeration plant remains helix tube type, use this equipment will build the refrigeration groove on the one hand, increase construction investment; In a single day evaporator reveals ammonia on the other hand, and with the influence water quality of growing seedlings, giving grows seedlings produces and bring the loss that can't retrieve.The 2nd, energy waste is serious, and will add hundreds of tons of low temperature seawaters every day in the kelp seedling cultivation process in the water system of growing seedlings, and simultaneously to hundreds of tons of low temperature seawaters of sea discharging, causes the energy to waste in a large number.The 3rd, it is undesirable to change the water effect, and kelp seedling cultivation adopts the circulation pipeline mode, and total back pool and storage cistern need be set, on one side draining on one side adds water when changing water, water quality can not get thorough improvement.
Summary of the invention: problem to be solved by this invention is exactly that background technology exists: the one, and refrigeration plant falls behind, and the evaporator in the refrigeration plant remains helix tube type, uses this equipment will build the refrigeration groove on the one hand, increases construction investment; In a single day evaporator reveals ammonia on the other hand, and with the influence water quality of growing seedlings, giving grows seedlings produces and bring the loss that can't retrieve.The 2nd, energy waste is serious, and will add hundreds of tons of low temperature seawaters every day in the kelp seedling cultivation process in the water system of growing seedlings, and simultaneously to hundreds of tons of low temperature seawaters of sea discharging, causes the energy to waste in a large number.The 3rd, it is undesirable to change the water effect, and kelp seedling cultivation adopts the circulation pipeline mode, and total back pool and storage cistern need be set, on one side draining on one side adds water when changing water, water quality can not get thorough improvement.Solving this technical problem the technical scheme that is adopted is: the improving one's methods of a kind of kelp seedling cultivation technological process, the seawater flow process of this method is: nature seawater passes through successively: gravity valveless filtering ponds, storage cistern, refrigeration system evaporator A, water at low temperature storage cistern, nursery pond, discharge by the waste water recovery pond from a nursery pond part again, another part to refrigeration system evaporator B, is got back to nursery pond through the secondary sand filter by back pool again; Wherein, refrigeration system evaporator A and refrigeration system evaporator B connect ammonia liquid reservoir, ammonia compressor, the evaporative condenser of refrigeration system separately respectively; It is characterized in that refrigeration system evaporator A and refrigeration system evaporator B are that ammonia divides plate to change the frozen water unit, the a part of seawater of nursery pond is preceding through the titanium plate type heat exchanger and from discharging again behind the part seawater to make heat exchange of storage cistern by the discharging of waste water recovery pond, flow to back pool by this part the seawater part from storage cistern after the heat exchange, another part flows to refrigeration system evaporator A.Wherein, each workshop is provided with independently back pool and one storage cistern independently, and the water in whole workshop all discharges when changing water, the pond is filled it up with is realized that thoroughly changing water improves water quality thereby extract new seawater from storage cistern again.The beneficial effect that the present invention is had compared with the prior art is: owing to adopt technique scheme, the first, original screw and vertical tube evaporator being improved to ammonia divides plate to change the frozen water unit, significantly improved refrigerating efficiency, reduced maintenance work, and thoroughly stopped evaporator ammonia and revealed and the danger of influence production.The second, because the waste water recovery pond is set, carry out discharging again after the exchange heat with fresh seawater earlier, make full use of the low-temperature energy sources in the waste water by the waste water of titanium plate type heat exchanger with discharging.Three, because each workshop is provided with independently back pool and one storage cistern independently, make that the water in whole workshop all discharges when changing water, the pond is filled it up with realized that thoroughly changing water improves water quality thereby extract new water from storage cistern again.
Description of drawings: Fig. 1 is a process chart of the present invention.Single arrow line is the water system flow process among the figure; Double arrowed line is the ammonia system flow process.
Embodiment: with reference to figure 1, improving one's methods of a kind of kelp seedling cultivation technological process, the seawater flow process of this method is: nature seawater passes through successively: gravity valveless filtering ponds, storage cistern, refrigeration system evaporator A, water at low temperature storage cistern, nursery pond, discharge by the waste water recovery pond from a nursery pond part again, another part to refrigeration system evaporator B, is got back to nursery pond through the secondary sand filter by back pool again; Wherein, refrigeration system evaporator A and refrigeration system evaporator B connect ammonia liquid reservoir, ammonia compressor, the evaporative condenser of refrigeration system separately respectively; It is characterized in that refrigeration system evaporator A and refrigeration system evaporator B are that ammonia divides plate to change the frozen water unit, the a part of seawater of nursery pond is preceding through the titanium plate type heat exchanger and from discharging again behind the part seawater to make heat exchange of storage cistern by the discharging of waste water recovery pond, flow to back pool by this part the seawater part from storage cistern after the heat exchange, another part flows to refrigeration system evaporator A.Wherein, each workshop is provided with independently back pool and one storage cistern independently, makes that the water in whole workshop all discharges when changing water, the pond is filled it up with is realized that thoroughly changing water improves water quality thereby extract new seawater from storage cistern again.
