Guardrail cleaning vehicle water heating system

Abstract

The invention relates to a guardrail cleaning vehicle water heating system, which includes an engine and a water jacket exhaust pipe, and also includes a heat exchanger, a circulating water pump, a water storage tank, an auxiliary water tank and a working pump. The heat exchanger, the water jacket exhaust pipe , the auxiliary water tank, the water storage tank and the circulating water pump are connected through pipelines in turn, and the working pump and the auxiliary water tank are connected through pipelines; the cleaning water is heated through the engine and the exhaust pipe, and the waste heat of the engine is used to heat the cleaning water, replacing the original electricity consumption. The heating system and the oil-fired boiler heat the cleaning water. It used to be heated in advance before work, but now it is heated by the waste heat of the engine. The hot water generated by the engine is stored in the auxiliary water tank for use by the working pump, and the excess hot water is returned to the storage tank. In the water tank, the cleaning water is heated in circulation, the heating temperature is high, the cleaning effect is good, the energy is saved, and the energy consumption is low.

Description

technical field [0001] The invention relates to a heating system, in particular to a water heating system for guardrail cleaning vehicles. Background technique [0002] The guardrail cleaning vehicle is mainly used for guardrail cleaning, cleaning deposits on the guardrail, and dust washing. It can also be used for cleaning industrial drainage pipes, walls, etc., city road isolation guardrails, and scrubbing of walls on both sides of the road. The guardrail cleaning vehicle can be equipped with sprinkler, suction device and high-pressure cleaning device, which integrates cleaning and suction. High-pressure water pumps and water guns can also be installed according to user needs, which are suitable for washing small urban advertisements and urban sculptures.

AI Technical Summary

Problems solved by technology

[0003] The urban isolation guardrail cleaning vehicles that have appeared in China use normal temperature cold water to wash the guardrail during cleaning operations. The cleaning device directly uses cold water to clean the guardrail. There are many disadvantages: First, in the cold winter period, the temperature in northern cities is very low. Still use cold water to clean the guardrail. When spraying water to clean, it will cause the surface of the guardrail to freeze, and the effect of cleaning the guardrail will not be achieved; The cleaning effect increases the difficulty of the maintenance of urban guardrails in winter; third, in order to improve the cleaning effect, it is necessary to set up electric heating systems, oil-fired boilers and other heating devices to heat the cleaning water, which consumes a lot of energy.
