Refrigeration can effectively reduce enterprise ice amount and air-conditioner power consumption, save mass energy consumption.
But the cold energy secondary recovery in aquatic products frozen product defrosting waste water that can be applied to of maturation utilizes not yet both at home and abroad at present
System and method.
The content of the invention
The purpose of the present invention is：It is proposed that cold energy secondary recovery utilizes system in a kind of aquatic products frozen product defrosting waste water, meeting will
Cold energy recycle in defrosting waste water cools down this demand in washings refrigeration and processing workshop, is ensureing aquatic products quality
Meanwhile the consumption of the energy in freezing aquatic product product process is greatly lowered, generate larger economic benefit and social benefit.
The present invention solve technical problem the technical solution adopted is that：
Cold energy secondary recovery utilizes system in the aquatic products frozen product defrosting waste water, and level-one is supplying cold directly system, using sewage
Heat exchanger directly obtains cold, and cooling cools down to aquatic products processing workshop for washings；Another grade uses heat pump system, and cooling is given
Aquatic products processing workshop air-cooler end cools down for aquatic products processing workshop.The cold energy secondary recovery can be complete using system
Independent operating.
The supplying cold directly system cooling mode is：High-efficiency sewage heat exchanger is placed in defrosting water- to-water heat exchanger pond, high
The refrigerating medium imitated in sewage heat exchanger exchanges heat with melt water, and the refrigerating medium after heat exchange is delivered to water by cold recovery circulating pump
Product processing workshop cools down for workshop washings, and refrigerating medium returns to sewage heat exchanger after cold transfers, and heat exchange again obtains cold
Amount.
The heat pump system cooling mode is：High-efficiency sewage heat exchanger is placed in defrosting water- to-water heat exchanger pond, and sewage changes
Refrigerating medium in hot device exchanges heat with melt water, and the refrigerating medium after heat exchange is transported to the cold of heat pump unit by heat pump cycle water pump A
Condenser, after the condenser heat absorption heating by heat pump unit, refrigerating medium is returned in sewage heat exchanger, and discharge heat reduces temperature
Degree.Meanwhile heat pump unit obtains the chilled water of low temperature by refrigerant circulation in evaporator, and it is delivered to processing of aquatic products vehicle
Between air-cooler end.It is raised by chilled water temperature behind processing of aquatic products workshop, by heat pump cycle water pump B, returns to heat pump machine
Down cycles again are organized, heat exchange again obtains cold, it is achieved thereby that the cooling in processing of aquatic products workshop.
When the supplying cold directly system can not meet the refrigeration requirement in processing of aquatic products workshop, by supplying cold directly system and
Heat pump system air conditioning needs to open V5, V2, V3, V8 valve at this time, closes V6, V1, V4, V7 valve.
Before the melt water of the melt water product zone is transported in defrosting water- to-water heat exchanger pond, defrosting water filtration water need to be passed through
Pond using micro- aeration-ultrafiltration membrance filter group technology water purification technology, removes suspended matter and soluble organic matter in defrosting waste water
Substances are waited, the energy carrier that cleaning is provided is utilized for follow-up cold energy secondary recovery.
The beneficial effects of the invention are as follows：By cold energy secondary recovery using system, applied in aquatic products frozen product defrosting waste water
Cold energy recycles, and meets the needs of washings refrigeration and workshop cooling, the energy in freezing aquatic product product process is greatly lowered
Consumption.
Description of the drawings
Fig. 1 is that cold energy secondary recovery utilizes schematic diagram in aquatic products frozen product defrosting waste water.
In figure：1- sewage heat exchangers, 2- cold recovery circulating pumps, 3- heat pump units, 4- heat pump cycle water pump A, 5- heat pumps
Water circulating pump B, V1, V2, V3, V4, V5, V6, V7 and V8 are valve.
Specific embodiment
The present invention is further described below in conjunction with the accompanying drawings.
As shown in Figure 1, cold energy secondary recovery includes supplying cold directly system and heat using system in aquatic products frozen product defrosting waste water
Pumping system.
Supplying cold directly system cooling mode is：High-efficiency sewage heat exchanger 1 is placed in defrosting water- to-water heat exchanger pond 11, high-efficient sewage
Refrigerating medium and melt water in water- to-water heat exchanger 1（8 DEG C or so）Heat exchange, 14 DEG C or so of refrigerating medium is followed by cold recovery after heat exchange
Ring pump 2, is delivered to processing of aquatic products workshop 10, cools down for workshop washings 8 or cooling fan system, refrigerating medium after cold transfers
About 25 DEG C of temperature, returns to sewage heat exchanger 1, and heat exchange again obtains cold.
Heat pump system cooling mode is：High-efficiency sewage heat exchanger 1 is placed in defrosting water- to-water heat exchanger pond, sewage heat exchanger 1
