High-pressure drive-in quick heating type electric boiler host machine and manufacturing process thereof

Abstract

The invention discloses a high-pressure drive-in quick heating type electric boiler host machine and a manufacturing process thereof. The manufacturing process comprises the steps of connecting N heating pipes in series so as to meet the requirement for working voltage value of 10 KV or more, installing the heating pipes in a heat exchange integrated module, and connecting the head ends and the tail ends of the heating pipes connected in series into a 10 KV high-voltage circuit to heat hot water (steam). The investment of a transformer can be saved, and electrical loss of the transformer can be saved by 15%. Under the action of a circulating pump, heated liquid (water and oil) passes through a sectional material heat exchange flow channel, a sectional material header pipe, a pipe joint anda water inlet / outlet main pipe to output hot water and steam. Through the characteristics of radiative heat transfer and nonconductivity of a far infrared radiation heating pipe, the possibility thathigh-tension electricity is transferred into a heat exchange sectional material is eradicated, the high-pressure drive-in quick heating type electric boiler host machine achieves the functions of water and electricity isolation and no electric leakage, is high in heat exchange efficiency, convenient to maintain and free of limescale and has the unique novelty and high practical value, and the power of the high-pressure drive-in quick heating type electric boiler host machine can be high and low, and the service life of the high-pressure drive-in quick heating type electric boiler host machineis 3-5 times longer thn that of a stainless steel heating pipe boiler.

Description

technical field [0001] The invention relates to the field of thermal energy, in particular to a main engine of a high-pressure direct-in rapid heating electric boiler and a manufacturing process thereof. Background technique [0002] At present, most electric boilers use heating tubes directly immersed in water to heat water to generate hot water and steam. There are many disadvantages such as serious scaling of heating tubes, voltage breakdown leakage, water leakage, and short service life of electric boilers. At present, most high-power electric boilers use 380V low-voltage electric heating, and the power loss of the transformer is 15%, resulting in a large waste of electric energy. High-power high-voltage electrode boilers are generally above 10MW.

[0002] At present, most electric boilers use heating tubes directly immersed in water to heat water to generate hot water and steam. There are many disadvantages such as serious scaling of heating tubes, voltage breakdown leakage, water leakage, and short service life of electric boilers.

At present, most high-power electric boilers use 380V low-voltage electric heating, and the power loss of the transformer is 15%, resulting in a great waste of electric energy.

High-power high-voltage electrode boilers are generally above 10MW. Due to the action of high-voltage electrode boiler pure water containers, conveying equipment, and carbon rod electrodes, impurities and free electrons cause pure water to be electrified, and high-temperature scale, grounding, insulating pipe joints and other components are affected by insulation, and The resistivity of pure water at 25°C is 18.3MΩ·cm. When the long-term operation is above 100°C, the impurities in pure water will increase and the resistance will decrease. If the operator neglects to change the water, it will cause the entire heating and hot water pipe The net is live, the consequences are unimaginable, especially for the heating of thousands of households, once there is a public casualty accident, it will cause public panic and terror
