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

Embodiment 1

[0039] Such as Figure 1-4 As shown, a waste heat recovery and utilization system for an aquarium includes a seawater storage tank 1, a display tank 2, a sewage tank 3, a condenser 5, an evaporator 6, and a heating device 7. The seawater storage tank 1 and The display pool 2 is connected through a water pipe equipped with a first electromagnetic valve 10 and a first centrifugal pump 11, and the display pool 2 and the sewage pool 3 are connected through a water pipe equipped with a second centrifugal pump 29 and a second electromagnetic valve 26. Such as figure 2 As shown, the seawater storage tank 1 is connected with a first circulation branch 9, and the first circulation branch 9 is provided with a first pneumatic butterfly valve 10-1, a first water pump 11-1, and a second pneumatic butterfly valve in sequence. 10-2. The third pneumatic butterfly valve 10-3, the condenser 5, the fourth pneumatic butterfly valve 10-4, and the fifth pneumatic butterfly valve 10-5. Both the wa...

Embodiment 2

[0051] On the basis of Embodiment 1, the present invention also provides a working method for the waste heat recovery and utilization system of the aquarium, which includes the following steps:

[0052] S1: When the seawater in the display pool 2 needs to be replaced, manually turn on the second centrifugal pump 29 and the second solenoid valve 26 to pump the warm seawater in the display pool 2 into the sewage pool 3 for standby; Enter the seawater storage tank 1 for subsequent use.

[0053] S2: start the control system, when the second temperature detection device detects that the seawater temperature in the seawater storage tank 1 is lower than the set value, the PLC controller sends a driving signal to control the execution of the following work: first, open the first circulation branch 9 The first pneumatic butterfly valve 10-1, the second pneumatic butterfly valve 10-2, the third pneumatic butterfly valve 10-3, the fourth pneumatic butterfly valve 10-4, the fifth pneumati...

Embodiment 3

[0059] Such as Figure 6 As shown, on the basis of embodiment 1, remove the filter screen of the rubber ball cleaning device 22, the water inlet filter screen of the first circulation branch 9 and the first sand tank filter 8, the water inlet of the second circulation branch 13 and the first The second sand tank filter 24 connects the water inlet and the water return port of the first circulation branch 9 through the heat dissipation coil 12 to form a closed circuit, the medium in the pipe is heat transfer oil, and the second circulation branch 13 The water inlet and the water return port are connected through the heat-absorbing coil 18 to form a closed circuit, and the medium in the pipe is heat-conducting oil. Wherein, the heat-resisting coil 12 and the heat-absorbing coil 18 are made of heat-resistant polyethylene, and in other embodiments, the material of the heat-dissipating coil 12 and the heat-absorbing coil 18 can also be made of triplicated polypropylene.

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...
