Description

Technical Field

[0001] This utility model relates to the field of waste heat utilization technology, and in particular to a waste heat utilization generator set. Background Technology

[0002] A generator set is a complete set of mechanical equipment that converts other forms of energy into electrical energy. It consists of a power system, control system, silencing system, vibration damping system, and exhaust system. Driven by a water turbine, steam turbine, diesel engine, or other power machinery, it converts energy from water flow, airflow, fuel combustion, or nuclear fission into mechanical energy, which is then transferred to the generator, converted into electrical energy, and output to electrical equipment. Existing technology publication CN207454127U proposes a waste heat recovery device for gas generator sets. This device evenly arranges heat exchangers within a circulating water tank and welds them to the periphery of the exhaust gas passage, increasing the heat exchange surface area to improve heat exchange efficiency. This scheme improves the waste heat recovery rate to some extent. However, a significant amount of heat cannot be fully recovered, resulting in a low recovery efficiency. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a waste heat utilization generator set, which fully recovers heat, improves the efficiency of the equipment in utilizing waste heat from exhaust gas, and enhances the ease of use.

[0004] To achieve the above objectives, this utility model provides a waste heat recovery generator set, including a heat exchange box, which is fixedly installed on the top of a base plate. A heat exchange mechanism is installed inside the heat exchange box, and a pressurization mechanism is installed on the top of the heat exchange box, with its input end connected to the interior of the heat exchange box. A power generation component is installed on the top right end of the base plate, with its input end connected to the output end of the pressurization mechanism. Exhaust gas is input into the heat exchange mechanism inside the heat exchange box to heat the water inside, generating steam which is then input into the pressurization mechanism. The pressurization mechanism then inputs the steam into the power generation component, driving a turbine to generate electricity, thus fully recovering the heat.

[0005] Preferably, the heat exchange mechanism includes a spiral heat exchange tube, an air inlet pipe, an air pump, multiple heat exchange fins, and a silencer. The spiral heat exchange tube is installed inside the heat exchange box, and multiple heat exchange fins are evenly installed on the spiral heat exchange tube.

An air pump is installed on the air inlet pipe, and the outlet end of the spiral heat exchange tube passes through the rear side wall of the heat exchange box and is connected to the silencer. When the air pump is started, exhaust gas is introduced into the spiral heat exchange tube through the air inlet pipe. The exhaust gas flows inside the spiral heat exchange tube and heats the water. The circulating spiral heat exchange tube can increase the flow time of the exhaust gas inside the heat exchange box, and at the same time, the heat exchange fins can increase the contact area between the spiral heat exchange tube and the water, so as to fully recover the heat.

A pressure gauge is connected to the output end of the steam tank, and an output pipe is connected to the output end of the steam tank. A pressure valve is installed on the output pipe. A dewatering filter plate is installed at the rectangular groove at the top of the heat exchange box. The generated steam is conveyed upwards and filtered by the dewatering filter plate to remove water vapor. The steam is collected through the collecting pipe and input into the steam tank through the gas supply pipe. The pressure is detected by the pressure gauge.

[0008] Preferably, the power generation assembly includes a housing, a rotating shaft, a turbine, a gearbox, and a generator. The housing is fixedly connected to the top right end of the base plate. The output end of the output pipe is tangentially connected to the upper part of the housing. The rotating shaft is rotatably mounted in the middle of the housing. A turbine is fixedly mounted on the outer wall of the rotating shaft. The output end of the rotating shaft is connected to the input end of the gearbox, and the output end of the gearbox is connected to the input end of the generator. When the pressure valve is opened, steam is input into the housing through the output pipe, driving the turbine to rotate the rotating shaft. The rotating shaft drives the generator to rotate through the gearbox to generate electricity for subsequent use.

[0009] Preferably, an exhaust pipe is connected to the bottom left side wall of the outer shell, and the output end of the exhaust pipe passes through the inside of the heat exchange box and is connected to a heat exchange cylinder. The heat exchange cylinder is fixedly installed inside the heat exchange box, and a steam discharge pipe is connected to the upper part of the heat exchange cylinder.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the exhaust gas is input into the heat exchange mechanism inside the heat exchange box, which heats the water inside the heat exchange box and generates steam, which is then input into the pressurization mechanism. The pressurization mechanism inputs the steam into the power generation component, which drives the turbine to generate electricity, thus fully recovering the heat and improving the efficiency of the equipment in utilizing the waste heat of the exhaust gas and the convenience of use.
