Heat transfer oil heating system with temperature accurate adjusting function

Abstract

The invention relates to a heat transfer oil heating system with the temperature accurate adjusting function. The heat transfer oil heating system comprises a main tube, at least one set of branches and an auxiliary heating system, wherein the main tube is used for allowing heat transfer oil to flow, the branches are led from the main tube, and the auxiliary heating system is used for conducting heating under the condition that no heat exists in the main tube; the set of branches comprise the oil inlet branch and the return oil branch, and an adjusting valve for adjusting the flow of the heat transfer oil is arranged between the oil inlet branch and heat equipment; an electric valve is arranged between the main tube and the auxiliary heating system; temperature sensors are arranged at the positions, close to a branch pipeline of the heat equipment, of the oil inlet branch and the return oil branch respectively, and the opening and closing state of the electric valve is controlled by the temperature sensors. According to the heat transfer oil heating system with the temperature accurate adjusting function, the temperature accurate control goal can be achieved by adjusting the flow, inlet oil of the main tube is controlled according to temperature measured by the temperature sensors close to the heat equipment, and oil temperature is further controlled; the auxiliary heating system is arranged, and therefore the temperature accurate control effect can still be achieved when no heat exists in the main tube.

Description

technical field [0001] The invention relates to a heat conduction oil heating system, in particular to a heat conduction oil heating system capable of precise temperature regulation. Background technique [0002] At present, the usual temperature-controlled heat transfer oil pipeline is composed of a heat transfer oil heating system and a heat transfer oil cooling system. Use the heating system and cooling system to make the heat transfer oil high or low temperature, and use the heat conduction between the heat transfer oil and the pipeline to control the temperature of the tank device that needs to be heated or cooled. The existing heat transfer oil heating system, whether it is layer combustion or chamber combustion, whether it is electric heating or other heat source heating, has the highest control accuracy of plus or minus one degree, and the coal furnace is basically plus or minus two to three degrees. In some links, the temperature of the main pipe is relatively high...
