A waste heat recovery and utilization system for aquariums and its working method

Abstract

The invention discloses a waste heat recycling system and a working method for an aquarium, belonging to the technical field of waste heat recycling, including a seawater storage tank, a display tank, a sewage tank, a condenser, an evaporator, a heating device and a control system , realize the recycling of waste heat in sewage, and use it for seawater heating in seawater storage tanks and display pools. It combines multiple heating methods to save energy while ensuring that the water temperature meets the living standards of marine organisms, and through the flow meter Measure the amount of water replenishment in the display pool to prevent overflow, add a filter device to the circulation branch of the display pool, and realize seawater filtration at the same time as heating, prolong the use cycle of seawater, reduce the frequency of water changes, save costs, and can detect the display pool and seawater storage in real time The water temperature and water level in the pool, through the driving signal sent by the PLC controller, control the opening and closing of relevant valves and pumps, and realize the automatic control of the water temperature and water level in the display pool and seawater storage tank.

Description

technical field [0001] The invention relates to the technical field of waste heat recovery and utilization, in particular to a waste heat recovery and utilization system for an aquarium. Background technique [0002] Marine life has high requirements on water quality and water temperature. During the operation and maintenance of the aquarium, various marine animal display pools need to change water regularly. The life support system of the aquarium refers to a set of equipment to maintain the survival of organisms and extend their lives. For the aquarium, the life support system is very important. Different marine organisms have different requirements for seawater temperature. Therefore, the life support systems of different aquariums in the aquarium need to be designed separately. Among them, the marine life display pools such as tropical fish and jellyfish need to be heated all year round. In order to maintain normal life, in the prior art, lithium bromide units or hot wat...

Problems solved by technology

For the aquarium, the life support system is very important. Different marine organisms have different requirements for seawater temperature. Therefore, the life support systems of different aquariums in the aquarium need to be designed separately. Among them, the marine life display pools such as tropical fish and jellyfish need to be heated all year round. , in order to maintain normal survival, in the prior art, lithium bromide units or hot water boilers are generally used to heat it, and replenishing water and maintaining a constant water temperature in the display pool need to consume a lot of energy for heating

However, the seawater discharged from the display pool contains a large amount of waste heat, which causes energy waste, which is not environmentally friendly, but also increases the operating cost of the aquarium; in addition, the replacement of the water in the life support system of the aquarium in the prior art mostly relies on manual water level adjustment. Water temperature monitoring, and manual control of the water pump for water change, water replenishment, etc., the labor cost is high
