Energy-saving and environment-friendly movable electric heating tank and heating method thereof

Abstract

The invention discloses an energy-saving and environment-friendly movable electric heating tank and a heating method thereof. The energy-saving and environment-friendly movable electric heating tank comprises a tank body, a semitrailer underframe, a heating system and an electronic control system, wherein the heating system comprises an oil filling circular pipeline, a heating and dehydrating filter circulating pipeline inside the tank, a heating main circulating pipeline inside the tank, a heating circulating pipeline outside the tank and an overpressure protection pipeline; the electronic control system comprises a heating liquid temperature detecting device arranged outside the tank, a heat conducting oil temperature detecting device arranged in a heating casing pipe group and a control device arranged in an equipment zone. According to the energy-saving and environment-friendly movable electric heating tank disclosed by the invention, the defect that an existing heating tank needs to be matched with a heat conducting oil furnace can be overcome; the energy-saving and environment-friendly movable electric heating tank has the advantages of simple structure, low investment, energy saving, environment friendliness, simple operation and convenient transportation and transition.

Description

technical field [0001] The invention relates to the field of road construction and maintenance machinery, in particular to an energy-saving and environment-friendly movable electric heating tank and a heating method thereof. Background technique [0002] The traditional movable heating tank system generally uses oil burners to provide heat. The equipment is complicated, the operation is cumbersome, the heat transfer efficiency is low, and the burning of heavy oil or diesel for heating wastes energy and pollutes the environment. [0003] In the traditional movable heating tank system, the asphalt or heavy oil is directly heated by the electric heating tube. Because the high temperature of the outer wall of the electric heating tube directly contacts the asphalt or heavy oil, the local temperature around the electric heating tube is high, and the thermal conductivity of the asphalt or heavy oil is not very good. Well, the heat generated by the pipe wall cannot be consumed quic...

AI Technical Summary

Problems solved by technology

[0004] In summary, the traditional heating tank has the following disadvantages: the heating tank and the heat transfer oil furnace must be used together, the equipment investment is large, the operation and maintenance are troublesome, the thermal efficiency is low, energy is wasted, the environment is polluted, and the heating cost of asphalt or heavy oil is high
