Industrial electric customized pipeline heater for water heating

Short Description:

Water tank circulation pipeline electric heater is a kind of energy-saving equipment that pre-heats the material, which is installed before the material equipment to realize the direct heating of the material, so that it can be heated in the high temperature cycle, and finally achieve the purpose of saving energy. It is widely used in the pre-heating of heavy oil, asphalt, clean oil and other fuel oil. The pipe heater is composed of two parts: body and control system. The heating element is made of stainless steel pipe as protection sleeve, high temperature resistance alloy wire, crystalline magnesium oxide powder, formed by compression process. The control part is composed of advanced digital circuit, integrated circuit trigger, high reverse voltage thyristor and other adjustable temperature measurement and constant temperature system to ensure the normal operation of the electric heater.

Working principle

Pipeline electric heater is a device that consumes electrical energy to convert it into thermal energy for heating materials that need to be. During operation, the low-temperature fluid medium enters its inlet under pressure, flows through the specific heat exchange channels inside the electric heating vessel, and follows path designed based on fluid thermodynamics principles, carrying away the high-temperature heat energy generated by the electric heating elements, thus increasing the temperature of the heated medium The outlet of the electric heater obtains the high-temperature medium required by the process. The internal control system of the electric heater automatically regulates the output power of the heater according to the temperature sensor signal at the outlet, maintaining a uniform temperature of the medium at the outlet; when the heating element overheats, the independent over protection device of the heating element immediately cuts off the heating power supply, preventing the heating material from overheating, causing coke, deterioration, and carbonization, and severe cases, causing the heating element to burn out, effectively extending the service life of the electric heater.

Working condition application overview

1) Overview of sewage heating pipeline electric heater

The electric heater is a kind of equipment which is mainly used for sewage heating in sewage treatment project. The electric heater converts electrical energy into heat energy to realize the heating effect of the sewage heating pipe and improve the efficiency and quality of the sewage treatment process.

2) Working principle of electric heater of sewage heating pipeline

The working principle of the electric heater in the sewage heating pipeline can be divided into two parts: electric energy conversion and heat transfer.

1. Electric energy conversion

After the resistance wire in the electric heater is connected to the power supply, the current through the resistance wire will produce energy loss, which is converted into heat energy, heating the heater itself. The temperature of the heater surface increases with the increase of the current, and eventually the heat energy of the heater surface is transmitted to the sewage pipe that needs to be heated.

2. Heat conduction

The electric heater transfers heat energy from the surface of the heater to the surface of the pipe, and then gradually transfers it along the wall of the pipe to the sewage in the pipe. The process of heat conduction can be described by the heat conduction equation, and its main influencing factors include pipe material, pipe wall thickness, thermal conductivity of heat transfer medium, etc.

3) Summary

The electric heater converts electrical energy into heat energy to realize the heating effect of the sewage heating pipeline. Its working principle includes two parts: electric energy conversion and thermal heat transfer, of which thermal heat transfer has many influencing factors. In practical applications, the appropriate electric heater should be selected according to the actual situation of the heating pipeline, and reasonable maintenance should be carried out.
