Device for recycling exhaust gas waste heat of internal combustion engine efficiently

Abstract

The invention relates to a device for recycling exhaust gas waste heat of an internal combustion engine efficiently, and belongs to the technical field of machine manufacturing. The device is mainly and technically characterized in that a heat exchange water tank is arranged at one end of a connecting pipe through a pipeline reversing device; a heat exchange layer is arranged in the heat exchange water tank; the other end of the heat exchange water tank is connected with an exhaust pipe of the water tank; and a water inlet pipe and a water outlet pipe are arranged on a water cavity of the heat exchange water tank. The device is simple in structure, reasonable in design, safe to use, convenient and high in heat efficiency and can save energy; a heat exchange area can reach more than one square meter; the waste gas heat energy produced by the internal combustion engine can be utilized reasonably and fully; in a normal running process, 1 liter of water can be boiled only in one minute; all workers on motor vehicles, steamships or engineering machines which are powered by internal combustion engines can use tail gas waste heat for boiling water, making tea and coffee, cooking and the like anytime anywhere, and homely trips for people on vehicles or ships are realized.

Description

1. Technical field [0001] The invention relates to a heat exchange device, in particular to a device for efficient recovery and utilization of waste heat from exhaust gas of an internal combustion engine, and belongs to the technical field of mechanical device manufacturing. 2. Background technology [0002] The internal combustion engine is a device that mixes liquid or gaseous fuel with air and directly enters the high-pressure combustion chamber inside the cylinder for combustion, and converts the released heat energy directly into power, and at the same time discharges exhaust gas with a large amount of heat energy. With the continuous improvement of the efficiency of the internal combustion engine, the application of catalytic technology and turbocharging technology has significantly increased the temperature of the exhaust gas to more than 750°C. In the future, with the further improvement of the performance of the internal combustion engine, the temperature of the exha...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the high-temperature waste gas discharged from the burning fuel of existing automobiles, ships, and construction machinery is not fully utilized and is wasted in vain. Some devices have unreasonable structural design and are far away from the engine. , the heat utilization rate of automobile exhaust gas is low, thus providing a new technical solution
