Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] Such as figure 1 As shown, a cogeneration heat recovery system includes a body 1, a power generation system and a heat exchange system. The power generation system includes a generator 21 and an engine 22 for driving the generator 21. The engine 22 is a gas engine 22. Both the power generation system and the heat exchange system are arranged in the body 1 . The heat exchange system includes a plate heat exchanger 31 for exchanging heat of cooling water of the engine 22 and a flue gas heat exchanger 32 for exchanging heat of exhaust gas of the engine 22 .

[0032] Among them, such as figure 1 As shown, the flue gas heat exchanger 32 includes a flue gas inlet 321, a flue gas outlet 322, a first water inlet 323 and a first water outlet 324; The smoke pipe 5 is provided with a three-way catalytic converter 51; the three-way catalytic converter 51 proces...

Abstract

The invention relates to a heat production and recovery system for a cogeneration unit, and belongs to the technical field of cogeneration. The system includes a machine body, a power generation system and a heat exchange system, wherein the power generation system comprises a generator, an engine for driving the generator to work and a heat exchange assembly for exchanging heat generated by the generator. When the system works, the engine rotates to drive the generator to work, the generator generates certain heat when working, and the heat generated by the generator is exchanged for utilization through the heat exchange assembly, so that the purpose of fully recycling the heat of the generator set is achieved. The efficiency of the whole system is effectively improved; the bulk temperature of the unit is reduced, and energy waste is reduced.

Description

technical field [0001] The invention relates to the technical field of heat and power cogeneration, in particular to a heat recovery system for a heat and power cogeneration unit. Background technique [0002] Combined heat and power, also known as combined heat and power. Combined heat and power can greatly improve the thermal efficiency of thermal power plants. Because, in general condensing units, the exhaust steam loss of the steam turbine is very large. The heat recovery system of the combined heat and power unit, through some methods, passes part or all of the steam through the steam turbine to do work, and then outputs it to the heat user to reduce the loss of exhaust steam. Moreover, the cogeneration of heat and power solves the problem of central heating in cities and replaces the small boilers blooming everywhere. [0003] The existing heat recovery system for combined heat and power units generally includes: a body, a power generation system and a heat exchange...
