Problems solved by technology

Because the system has undergone multiple heat transfers, the heat exchange efficiency is low and the heat loss is large. In extreme weather, electric heating or gas heating is often required to meet the bathing requirements. While the overall operating cost is high, the heating coefficient of performance is low

Embodiment 1

[0037] like figure 1 As shown, this embodiment provides a mine water source waste heat recovery and utilization hot water bathing system, including a mine water reservoir 1, a heat exchanger 2, a heat pump unit 3 and a water storage tank 4, and the heat pump unit 3 is provided with interconnected Interface 1, interface 2 and interconnected interface 3 and interface 4; the water outlet, interface 3, interface 4 at the bottom of the water storage tank 4 and the water inlet at the top of the water storage tank 4 are connected in turn through pipelines to form a circulation loop, and the water storage tank 4. A circulating water pump 5 is fixedly installed on the pipeline between the water outlet and the interface 3; the bathing opening at the bottom of the water storage tank 4 is connected with one end of the bathing pipeline, and a turning pump 6 is fixedly installed on the bathing pipeline;

[0038] The heat exchanger 2 is provided with the interconnected interface five and the...

Embodiment 2

[0045] On the basis of Embodiment 1, this embodiment further includes a water softener processor, which is communicated with the water storage tank 4 through a water replenishment pipeline, and a control valve-9 is fixedly installed on the replenishment pipeline.

[0046] When working, it is necessary to replenish water to the water storage tank 4 regularly. During the replenishment process, the tap water is softened by a water softener to remove the calcium and magnesium plasma in the tap water, and the tap water with high salinity is converted into softened water to avoid the inside of the equipment. fouling, so as to avoid affecting the heat exchange efficiency and water flow transmission, and ensure the heating efficiency of the entire system.

Embodiment 3

[0048] On the basis of Embodiment 2, this embodiment also includes a controller. The water storage tank 4 is fixedly installed with a liquid level controller 10 and a thermometer 11. The liquid level controller 10, the thermometer 11, the control valve 1 9 and the heat pump unit 3 respectively communicate with the controller.

[0049] When working, the temperature of the water in the water storage tank 4 is monitored in real time through the thermometer 11, and the corresponding temperature signal is sent to the controller, and the controller receives the corresponding temperature signal and judges and analyzes; when the water temperature in the water storage tank 4 reaches 43 ℃ At the time, the controller turns off the heat pump unit 3, and the controller starts the turning water pump 6, and the turning water pump 6 sends out the water in the water storage tank 4 for bathing;

[0050] At the same time, the water level in the water storage tank 4 is monitored in real time by t...

Abstract

The invention relates to a mine water source waste heat recycling hot water bathing system which comprises a mine water reservoir, a heat exchanger, a heat pump unit, a water storage tank and a soft water processor, and the heat pump unit is provided with a first connector, a second connector, a third connector and a fourth connector; a water outlet in the bottom of the water storage tank, the third connector, the fourth connector and a water inlet in the top of the water storage tank are communicated through a pipeline, and a circulating water pump is fixedly installed on the pipeline. A bathing opening in the bottom of the water storage tank is communicated with one end of a bathing pipeline, and a water turning pump is fixedly mounted on the bathing pipeline; the heat exchanger is provided with a connector V, a connector VI, a connector VII and a connector VIII, the connector VII, the connector I, the connector II and the connector VIII are communicated through a pipeline, and an intermediate water circulating pump is mounted on the pipeline; a mine water suction pump is installed at a water outlet in the bottom of the mine water reservoir, and a water outlet of the mine water suction pump is communicated with the sixth connector through a pipeline. The mine water can be fully utilized as a heat source for bathing, the bathing requirement is met, energy consumption is reduced, energy is saved, and the environment is protected.

Description

technical field [0001] The invention relates to the technical field of mine water waste heat recovery, in particular to a hot water bathing system for mine water waste heat recovery and utilization. Background technique [0002] my country's coal is mainly mined underground. In order to ensure safe underground production, a large amount of mine wastewater (referred to as "mine water") must be discharged. The temperature of this part of the mine water is constant throughout the year, and the amount of water varies with the continuous expansion of the mine production scale and mining time. The growth of mine water will gradually increase. It is a stable and high-value cold and heat source, and it is also a kind of clean energy. It is an ideal environment for extracting thermal energy from water. However, most mines ignore the use value of mine water. The heat energy is often lost with the discharge of mine water, resulting in waste of heat sources. If it is recycled, it is nece...
