Problems solved by technology

Since the waste heat temperature is lower than 300°C, it is not suitable to use water as the working medium to generate electricity. As a result, in recent years, the use of organic working medium Rankine cycle power generation waste heat recovery system has also attracted more and more attention. The electricity is used for people's daily needs, such as domestic hot water production, refrigeration and air conditioning, heating and heating, etc., but there is another problem that the condensed water heat of pure waste heat power generation will be wasted, and when the waste heat temperature is low , use the generated electricity to make domestic hot water, refrigeration and air conditioning, heating and heating systems, etc., facing the problem of large losses in the process of multiple energy conversions

Embodiment 2

[0074] To recover the heat from the medium-temperature flue gas discharged from the industrial kiln, the method of producing hot water in the present invention adopts the following operation two:

[0075] 1. When starting to work, the hydrogen in the low hydrogen equilibrium pressure hydrogen storage alloy reactor 1 is saturated, and when the temperature sensor 6 detects that the flue gas is in the middle temperature range of 100 to 200°C, under the control of the control unit 5, start simultaneously The first circulating fan 21, the sixth electromagnetic valve 14 are opened, the seventh electromagnetic valve 27 is opened, the second electromagnetic valve 24 is opened, the suction pump 28 is started, the thirteenth electromagnetic valve 15 is opened, the third circulating pump 13 is started, and the eighth electromagnetic valve is opened. Valve 23 is opened, and all other solenoid valves or pumps are closed.

[0076] The flue gas in the middle temperature range of 100 to 200°C...

Embodiment 3

[0100] For the recovery of low-temperature flue gas, the three operations of the hot water production operation mode of the present invention are as follows:

[0101] 1. When starting to work, the hydrogen in the low hydrogen equilibrium pressure hydrogen storage alloy reactor 1 is saturated, and when the temperature sensor 6 detects that the flue gas temperature is in the low temperature range of 50 to 100°C, under the control of the control unit 5, Start the suction pump 28, open the first circulating fan 21, open the first electromagnetic valve 22, open the second electromagnetic valve 24, open the third electromagnetic valve 29, start the third circulating pump 13, open the thirteenth electromagnetic valve 15, and open the remaining electromagnetic valves Or both pumps or fans are off.

[0102] The flue gas in the low temperature range of 50 to 100°C passes through the first fan 21, the first electromagnetic valve 22, the second electromagnetic valve 24, and the low hydrog...

Abstract

The invention discloses a thermal electricity and thermal water supply system of a waste heat recycling pipeline and a running method of the thermal electricity and thermal water supply system, and belongs to the technical field of low-grade energy heat recycling and application. According to the thermal electricity and thermal water supply system of the waste heat recycling pipeline and the running method of the thermal electricity and thermal water supply system, waste heat temperature is taken as a monitored object, and a plurality of electromagnetic valves control selective switching of the waste heat flow way direction; hydrogen storing alloy reactors in the waste heat recycling circulation pipeline are alternatively driven, or a water heater is directly driven, or a waste heater boiler and the hydrogen storing alloy reactors are driven; therefore, multi-stage heat exchange is carried out on low-grade energy within the different-temperature range, the gradient utilization and depth waste heat recycling is achieved, and uninterrupted hot water and / or power can be provided for production of an enterprise and life of the staff. No working liquid destroying the ozone sphere is adopted in the whole recycling process, and the system and method save energy, and are environmentally friendly, efficient and free of pollution.

Description

technical field [0001] The invention relates to an application system of waste heat recovery circulation pipeline, which belongs to the technical field of waste heat recovery application of low-grade energy. Background technique [0002] Many enterprises such as papermaking, glass, and metallurgy cannot do without industrial boilers, and this production link is also an important part of enterprise consumption and production costs. In fact, no matter what kind of fuel the boiler produces, a large amount of waste heat and pressure will be generated. Therefore, the recovery and utilization of waste heat and pressure should be done well, and it should be directly applied to the preheating of raw materials in the previous process of the production process, as well as the work of enterprise employees. In daily life, a considerable amount of fuel will be saved every year, which is one of the key tasks of energy conservation and emission reduction, benefiting the country and the peo...
