Vehicle engine plumbing exhaust heating medium water purification filter device and its application system

Abstract

The invention discloses a device for purifying and filtering vehicle engine water-heating tail gas heating medium water and an application system thereof. The device comprises a purifying filter for purifying and filtering heating medium water, a water inlet electromagnetic valve arranged at one side of the purifying filter, a water outlet electromagnetic valve arranged at the other side of the purifying filter and a controller for controlling the purifying filter, the water inlet electromagnetic valve and the water outlet electromagnetic valve respectively; and the controller is electrically connected with the purifying filter, the water inlet electromagnetic valve and the water outlet electromagnetic valve. The device for purifying and filtering the vehicle engine water-heating tail gas heating medium water and the application system thereof can be used for overcoming the defects of blocked flowing in pipelines, easy clogging of pipelines, low energy utilization rate, low reliability and the like in the prior art, and has the advantages of unblocked flowing in pipelines, difficult clogging, high energy utilization rate and high reliability.

Description

technical field [0001] The invention relates to the technical field of vehicle engines, in particular to a vehicle engine plumbing tail gas heating medium water purification filter device and an application system thereof. Background technique [0002] At present, my country's intercity buses, urban buses, medium and heavy passenger cars, trucks, and construction machinery are almost all powered by natural gas engines, diesel engines, and gasoline engines, and the exhaust heat energy loss of these engines accounts for about 55% of the total useful work. . Today, when energy is in short supply and human beings are facing obstacles to sustainable development, water heating and the utilization of exhaust heat are getting more and more attention for heating vehicles and construction machinery. [0003] Vehicle engine water heating and exhaust gas heating system medium water, often due to the steel and metal fragments, steel metal particles and non-metal fragments, non-metal part...

AI Technical Summary

Problems solved by technology

[0006] (1) Corrosion: due to the water and acid components in the circulating medium water, long-term use causes the corrosion of the circulating water pipe and the circulating waterway is not smooth or the pipe is blocked;

[0007] ⑵ The antifreeze fluid is blocked and the burst pipe is lost, and the vehicle cannot be used:

[0008] Since the vehicles using plumbing exhaust gas close the circulating waterway in summer, it is more likely to cause the accumulation of rusted debris and particles. The circulating waterway is not smooth or the pipeline is blocked, which affects the normal operation of the plumbing exhaust heat exchange device. At the same time, when the pipe is blocked and burst, a large amount of antifreeze fluid in the circulating water will be lost, which will increase the economy of the car. In severe cases, the vehicle will be unusable

[0009] In the process of realizing the present invention, the inventor found that there are at least defects in the prior art such as blocked pipelines, easy blockage, low energy utilization rate and low reliability.
