Efficient and flexible interaction distributed energy waste heat utilization system and work method thereof

Abstract

The invention relates to an efficient and flexible interaction distributed energy waste heat utilization system and a work method thereof and aims at solving the supply and demand contradiction between a supply side and a user side and the running problem. The efficient and flexible interaction distributed energy waste heat utilization system comprises a prime motor, a first-stage smoke-water heatexchanger, a lithium bromide unit, a second-stage smoke-water heat exchanger, a regulating system, a heat pump and a hot water distributor. The prime motor, the first-stage smoke-water heat exchanger, the lithium bromide unit and the second-stage smoke-water heat exchanger are sequentially connected, and the prime motor, the lithium bromide unit and the second-stage smoke-water heat exchanger areconnected with the user side. A cylinder jacket water outlet of the prime motor is connected with the lithium bromide unit, the first-stage smoke-water heat exchanger is connected with the heat pump,the first-stage smoke-water heat exchanger and the second-stage smoke-water heat exchanger are connected with the user side through the hot water distributor, and the heat pump is also connected withthe user side. By means of the efficient and flexible interaction distributed energy waste heat utilization system and the work method thereof, on one hand, the distributed energy efficiency is effectively improved, on the other hand, the steam supply problem is solved, and great social benefits and economic benefits are achieved.

Description

technical field [0001] The invention belongs to the field of energy, and relates to an efficient, flexible and interactive distributed energy waste heat utilization system and a working method thereof. Background technique [0002] Distributed energy, as a cutting-edge technology for substantial energy saving, is one of the four cutting-edge technologies in the energy field of my country's medium- and long-term scientific and technological development planning. It has the advantages of small size, high efficiency, cleanness, and closeness to users. The energy system has important practical significance and far-reaching strategic significance. [0003] At present, distributed energy mainly uses gas turbine or gas internal combustion engine as the prime mover. Distributed energy with gas internal combustion engine as the prime mover generally provides energy such as cooling, heating and power for hospitals, hotels, commercial complexes, office buildings, etc., such as patent No...

Problems solved by technology

[0003] At present, distributed energy mainly uses gas turbine or gas internal combustion engine as the prime mover. Distributed energy with gas internal combustion engine as the prime mover generally provides energy such as cooling, heating and power for hospitals, hotels, commercial complexes, office buildings, etc., such as patent No. 201720678899.1 The main disadvantage of the Chinese patent is that the efficiency of the unit is low when the demand for cold and heat is low in spring and autumn; in addition, such as the catering industry, clothing industry, food industry, etc. have steam demand, and the conventional configuration cannot provide steam, which restricts the following Development of distributed energy based on gas internal combustion engine
