Waste heat distilled drinking water device for vehicle diesel engine

Abstract

The invention discloses a waste heat distillation drinking device of an automotive diesel engine. The waste heat distillation drinking device comprises a vaporizer, a condensation water tank and a water dispenser. The vaporizer comprises a connecting straight pipe and a spiral pipe. The inner wall of the connecting straight pipe is provided with a spiral groove matched with the spiral pipe, and the spiral pipe is screwed into the spiral groove. The outer wall of the connecting straight pipe is provided with two hollow cylindrical bosses, through holes of the cylindrical bosses are communicated with the spiral groove, the two ends of the spiral pipe are connected with a connecting welding pipe in a sealing mode, and a water inlet and a steam outlet are formed by the connecting welding pipe and the cylindrical bosses. The condensation water tank is provided with a water outlet, and internally provided with a condenser pipe. The water inlet of the vaporizer is connected with the water outlet of the condensation water tank, the steam outlet of the vaporizer is connected with the steam inlet end of the condenser pipe, and the water outlet end of the condenser pipe is connected with the water dispenser. The drinking device effectively utilizes the waste heat of the engine for vaporizing water, after condensation, clean and sanitary distilled water is obtained to be drunk by people, energy resources are saved, and the emission heat of automobiles is reduced.

Description

technical field [0001] The invention belongs to the technical field of automobile energy saving, in particular to utilization of engine waste heat, in particular to a vehicle diesel engine waste heat distillation drinking water device. Background technique [0002] In the total heat of the engine fuel, only 30%-45% of the heat is converted into effective work, and the remaining 55%-70% is lost. Among them, the exhaust gas is mainly taken away, and the second is lost through the coolant. Corresponding to 25%-45% of the heat taken away by the exhaust gas of the diesel engine, the exhaust temperature is 700-900K. How to improve the utilization rate of heat energy or use the energy of exhaust gas to achieve the purpose of energy saving has always been the goal pursued by researchers of automobiles and engines. Exhaust gas turbocharging technology is a successful example in the utilization of available energy from engine exhaust gas. At present, domestic engine waste heat util...

Problems solved by technology

[0005] The purpose of the present invention is to provide a device for distilling and drinking water with residual heat of diesel engines for vehicles. Under the premise that the original exhaust back pressure of the engine is not affected and the exhaust loss is not additionally increased, the high temperature in the exhaust gas discharged by the diesel engine is used to obtain steam. Distilled water is obtained through condensation to solve the problem of lack of clean and hygienic drinking water for passengers during the journey
