Problems solved by technology

[0003] There are obvious defects in these practices: a large amount of groundwater is extracted for aquaculture, which seriously wastes groundwater resources, and will cause ground surface subsidence, groundwater table drop, water recharge, soil issues such as salinization
Coal-fired boilers not only have high operating costs, but also have poor safety, low energy utilization, waste of resources and serious air pollution
[0004] A large amount of heat and cold in the drainage of the breeding factory is not recycled and directly discharged, resulting in a great waste of energy

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and examples.

[0032] see figure 1 , the steps of multi-energy comprehensive utilization and heating of the present invention are as follows:

[0033] Step (1): Detect the temperature T10 of No. 1 water (aquaculture water, the same below) and compare it with the water temperature T30 in the solar water tank. If the value of ΔT1=T30-T10 reaches the set value (such as ΔT1≥5°C), The solenoid valve DF1 is opened, and the water pump B1 and the water pump B2 are started at the same time. The normal temperature water of No. 2 water (deep well water, the same below) passes through the solar heat exchanger (JH1) for heat exchange and extracts the heat energy of the solar energy; after detecting the solar heat exchanger (JH1) The water temperature T11 of the No. 1 water at the end, compare T11 with the upper limit T1 and lower limit T2 of the water temperature setting required by...

Abstract

The invention is a multi-energy comprehensive utilization and water temperature control method for industrialized aquaculture, which comprehensively utilizes the heat energy of solar energy, the cold and heat energy in deep water wells, and the cold and heat energy of wastewater in aquaculture ponds, and realizes aquaculture through heat exchangers and water source heat pumps. Comprehensive utilization of water and temperature control, without using boilers, and without excessive use of groundwater resources. Therefore, there is no pollution to the environment. The heat (cold) energy of the groundwater utilized by the primary heat exchange is used for the heat pump unit, and the cold and heat energy of the water recovered from the culture pond is utilized, so the present invention has higher energy utilization rate.

Description

technical field [0001] The invention relates to a multi-energy comprehensive utilization of water for aquaculture and a method for heating and cooling water temperature regulation. Background technique [0002] For aquaculture, water temperature regulation is a key technology. Shrimp, shellfish, and sea cucumber seedlings require a water temperature of around 22°C to 25°C; while cold-water fish such as turbot require a water temperature below 20°C. At present, the practice of most breeding enterprises is to use the hot water produced by the boiler as the heat source for heating water during the period from November to May in the northern region. In the southern region, the natural environment water temperature can reach above 30°C in summer, which greatly exceeds the growth temperature of some aquatic products. The existing method is to use groundwater as a cold source of water, or directly extract groundwater for aquaculture. [0003] There are obvious defects in these me...
