Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchange equipment, and more specifically relates to a device for heating a breeding pond by taking seawater as a heat source. Background Art

[0002] At present, marine aquaculture has been rapidly developed. Due to the particularity of marine aquaculture, it is necessary to provide heat source uninterruptedly to meet the needs of maintaining a constant temperature in the aquaculture pond and improving the aquaculture efficiency. The heat exchange equipment in the prior art generally has the problem of being easily damaged in one way or another; it often causes the failure of the heat exchange equipment and is shut down for maintenance, and cannot provide heat source for the aquaculture pond, which affects the temperature of the aquaculture pond and affects the aquaculture efficiency.

[0003] The invention patent with patent number 201510813299.7 discloses a heat exchange mechanism for a seawater desalination system, including a pressure reducing mechanism, a heat exchange mechanism and a pressure boosting mechanism. The pressure reducing mechanism includes a pressure reducing pipeline and an expansion valve, the heat exchange mechanism includes a heat exchange pipeline and a heat exchanger, and the pressure boosting mechanism includes a pressure boosting pipeline and a compressor. A hot working medium flows in the heat exchange pipeline, and a water turbine is arranged on the heat exchange pipeline. The water turbine is driven by the hot working medium in the heat exchange pipeline and drives the compressor through a connecting rod shaft. The present invention abandons the condenser in the traditional desalination technology, avoids the largest heat loss in seawater desalination, the condensation heat loss, and uses industrial circulating water as the hot working medium, which improves the recovery rate of heat energy. At the same time, the function of the hot working medium is reasonably utilized to make it a power source for the compressor.

[0004] This patented technology solves the problem of seawater heat exchange to a good extent. However, a large amount of salt will be generated during the desalination and evaporation of seawater, which will corrode the evaporator and cause failure, seriously affecting the heat exchange process.

[0005] The invention patent with patent number 202210622473.X discloses a high-efficiency aluminum plate-fin heat exchanger for utilizing seawater, including a heat exchanger mounting frame for mounting fins, and the heat exchanger mounting frame is equipped with a seawater inlet end, a seawater outlet end, a heat source input end and a heat source output end. The seawater inlet end is also connected to one of the input ends of multiple heat exchanger mounting frames by the same inverted U-shaped connecting pipe, and a chemical reaction component for softening seawater is also provided in the inverted U-shaped connecting pipe. The chemical reaction component includes a cation exchange resin installed in the connecting pipe and provided for displacing calcium and magnesium ions in seawater. The heat exchanger mounting frame is also provided with a water bath component for increasing the replacement reaction rate.

[0006] This application solves a series of problems such as the scale easily generated inside the heat exchanger when using seawater for heat exchange, which affects the heat exchange efficiency of the heat exchanger. However, it uses multiple adjacent rubber strips and multiple compression springs, which greatly increases the probability of equipment damage, thereby affecting heat exchange and is not suitable for use in marine aquaculture that requires uninterrupted heating.
