Description

Technical Field

[0001] This utility model relates to the field of engine exhaust gas utilization technology, and in particular to a device for recovering and reusing the energy of exhaust gas from a high thermal efficiency engine. Background Technology

[0002] An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, and electric motors. Internal combustion engines typically convert chemical energy into mechanical energy. When an engine is working, only a portion of the energy produced by the engine is used; the exhaust gas is generally quite hot and contains a large portion of its energy, which is wasted and cannot be fully utilized. The existing technology has the following problems: Existing engine sets rarely use exhaust waste heat recovery systems, so the heat carried away by the exhaust is directly dissipated into the atmosphere, resulting in energy loss and hindering the comprehensive utilization of energy. Secondly, the black smoke containing particulate matter in the exhaust gas of the engine set is directly discharged into the atmosphere, which can easily cause environmental pollution.

It adopts the cooperation between engine set, insulation component, conveying pipeline, heating unit and air inlet pipe. The exhaust gas generated by the engine set is conveyed to the heating unit through the conveying pipeline to heat the water in the heating unit. The heat generated by heating raises the temperature of the air in the insulation component. Combined with the start of the exhaust fan on the insulation component, the indoor temperature is increased. At the same time, the hot water in the heating unit can be discharged and reused. This solves the problem that existing engine sets rarely use exhaust waste heat utilization systems. In this case, the heat carried away by the exhaust is directly dissipated into the atmosphere, resulting in energy loss and which is not conducive to the comprehensive utilization of energy. This invention achieves the beneficial effect of improving the energy recovery and reuse efficiency of exhaust gas generated by engine set.

[0013] 2. This utility model provides a high thermal efficiency engine exhaust gas energy recovery and reuse device.
