Problems solved by technology

[0018] However, the waste heat power generation system according to the prior art has the following disadvantages: that is, a muffler and an exhaust gas heat exchanger are respectively installed on the exhaust gas discharge channel, so that not only the noise is large, but also a large space is occupied, and it is necessary to carry out Twice the setup work, so it will take too much job time and cost
[0019] It can be seen that there are still many defects in the muffler and the exhaust gas heat exchanger in the above-mentioned existing waste heat power generation system, and they need to be improved.

Abstract

A heat exchange muffler of a waste heat generating system is made of a muffler and a coolant pipe that exchanges heat with the exhaust gas. With the heat exchange muffler having both functions, it reduces the occupation space of the components, simplifies in structure and saves cost.

Description

technical field [0001] The present invention relates to a waste heat power generation system, more precisely, it relates to a waste heat power generation system in which a heat exchanger and a muffler are integrated, which can not only reduce noise, but also reduce the space and cost occupied by components, and improve work efficiency The invention of the heat exchange muffler. Background technique [0002] Generally speaking, cogeneration system is called cogeneration system. In detail, a cogeneration system is a system that simultaneously produces electricity and heat from one energy source. [0003] As described above, the cogeneration system can generate electricity by driving an engine or a turbine, and recover exhaust gas heat or waste heat of cooling water generated during the electricity generation. Therefore, the comprehensive thermal efficiency can be increased to 70~80%. In this way, it can be widely used in electricity and heat sources of buildings. In partic...
