Temperature control device in seawater breeding pond water reflow treatment

Abstract

The invention provides a temperature control device in seawater breeding pond water reflow treatment. The temperature control device comprises a reflow water tank, a breeding pond and a heat exchange pump; the temperature control device is characterized in that a heat storage water tank and a plurality of heat exchangers are additionally arranged; one water outlet of the heat exchange water tank is communicated with a solar water heater through a water pump; the water outlet of the solar water heater is communicated with a water inlet of the heat storage water tank; another water outlet of the heat storage water tank is communicated with a heat source main pipe through a water source heat pump; the heat source main pipe is communicated with a plurality of heat source branched solenoid valve pipelines; each reflow branch pipe is communicated with the liquid inlet of the corresponding heat exchanger; the liquid discharge port of each heat exchanger is communicated with a reflow port of the breeding pond; each heat source branched solenoid valve is communicated with the water inlet of the corresponding heat exchanger through a heat source branch pipe; the water outlet of each heat exchanger is communicated with a reflow main pipe through a reflow branch pipe; and the reflow main pipe is communicated with the reflow port of the heat storage water tank. The temperature control device provided by the invention has the advantages that no seawater desalination phenomenon exists in reflow water indirect heat exchanging, and the seawater breeding effect is ensured, and moreover, the solar energy and the water source heat pump are complementary.

Description

Technical field: [0001] The invention relates to a seawater culture backflow utilization mechanism, in particular to a temperature control device in seawater culture pond water backflow treatment. Background technique: [0002] Mariculture generally uses pumps to pump seawater from the sea and then injects it into aquaculture ponds for fish farming. During the aquaculture process, the sewage discharged by fish affects the fish aquaculture environment, so it is necessary to continuously discharge sewage and then replenish pumped seawater for injection. This operation of continuously pumping seawater makes the water pump consume a lot of energy, and at the same time continuously discharges sewage into the sea, which is not conducive to environmental protection. Therefore, now the breeders return the sewage discharged from the culture ponds to the culture water for reflux treatment, and then return them to the culture ponds for cultivation, which not only saves energy, but also...
