Embodiment 2

[0029] There is 60-70 ℃ waste heat in large chemical equipment, which needs to be cooled by the circulating water in the cooling tower. After the circulating water flows back into the cooling tower, the heat is discharged into the atmosphere. The present invention can utilize the low-grade waste heat of 60-70°C. In this embodiment, the 60-70°C hot water is the low-grade heat source to be collected by the device of the present invention.

[0030] In addition, the heat pump is a device that transfers heat by compensating for the consumption of some low-grade heat sources. Traditional heat pumps use natural resources, such as the energy stored in outdoor air, soil, ocean, etc., but often due to the low energy of these substances, the temperature that the heat pump can reach is not very high. The first heat exchanger of the present invention and the heat pump system are connected into an integrated structure, so that the heat pump can obtain higher temperature circulating water to...

Embodiment 3

[0038] Due to the physical properties of the lithium bromide solution in the lithium bromide absorption refrigeration system, the efficiency is relatively low when the refrigerant water at a lower temperature is produced at a temperature of 80°C or below. There is unutilized waste heat of 65-80°C in the boiler. In this embodiment, the present invention is connected with the lithium bromide refrigeration system into an integrated structure, and the above-mentioned 65-80°C waste heat is used as the low-grade heat source to be collected by the heat source collector.

[0039] see image 3 , image 3 It is a schematic flow chart of the device of the present invention used in a single-effect lithium bromide absorption refrigeration system. The heating device includes a heat source collector 1, a gas storage 2, a vortex tube 3, a first heat exchanger 4, a first condenser 15, a first solution pump 16, a second heat exchanger 7, and a third heat exchanger 8, the second condenser 9, ...

Description

technical field [0001] The invention relates to an energy utilization device, in particular to a heating device utilizing a low-grade heat source. Background technique [0002] Energy is the material basis of social life and the material resource in nature that provides power for people's daily life. Fossil energy sources such as coal, oil, and natural gas provide sources of production materials and production power for industries such as steel, textiles, chemicals, and medical care. Energy is the lifeblood of the national economy and plays an important role in promoting the country's industrial development. However, the world's energy supply is increasingly tense, and countries have introduced new strategies to deal with the reduction of energy. A large amount of heat is released during the combustion of fossil energy such as coal, oil, and natural gas. Taking advantage of this feature, many large-scale power stations, steel plants and other large-scale equipment have bee...
