Compared to boilers, which is better and which is easier to use?
Generally speaking, each has its advantages and disadvantages. Coal fired boilers and other boilers have lower actual operating costs and can support larger heat demand; However, there are also many shortcomings, such as environmental pollution and easy to cause safety accidents (belonging to special equipment with high pressure and high temperature). It is widely used in various industrial fields.
The advantages of heat transfer oil heaters are: easy to use, safe, low maintenance costs, simple or no procedures, and they are clean and environmentally friendly to the environment; However, there are also corresponding shortcomings: the use cost is relatively high (mainly reflected in the electricity bill), which is more suitable for use on equipment with a small demand for thermal energy.
With the increasingly serious environmental pollution, the use of boilers will be restricted, and there will be a large replacement space and market for heat transfer oil heaters. In 2015, Daheda Thermal Oil Heater will provide customers with the best temperature control equipment and the best sales service.
Principle of heat transfer oil heater: The heat transfer oil heater directly inserts the heating element into an organic carrier (heat transfer oil) for direct heating. A circulation pump is used to force the heat transfer oil to undergo a liquid phase circulation, transferring heat to one or more heat consuming devices. After being unloaded by the heat consuming device, the heat is re passed through the circulation pump, returned to the heater, reabsorbed, and transferred to the heat consuming device. This cycle is repeated to achieve continuous heat transfer, Raise the temperature of the heated object to meet the heating process requirements.
Application of heat transfer oil heater: widely used in various heat industries such as high-temperature setting, plate heating, rubber, drying, printing and dyeing, chemical industry, plywood production, waterproof roll production, asphalt heating non-woven hot rolling machine, fiberglass hot press, reaction kettle, mold, drying room, oven, etc.
1. Used for heating fluid media in industries such as oil fields, refineries, and chemical plants.
2. Various types of water heating, including water heating in civil bathrooms and industrial process water.
3. Heating of hydrocarbons, including heat transfer oil, fuel oil, asphalt, paraffin, and so on.
4. Gas heating, including H2, N2, and various inert and organic gas mixtures.
5. Heating of cleaning machines and ice melting tanks, including NaOH solution and various detergents.
6. Air heating is suitable for drying some powders, chemical processes, and jet drying under certain pressures.
7. Heating of superheated steam.
Characteristics of heat transfer oil heater:
1. High quality heat source heat transfer oil heating system can output hot oil of up to 350 ℃ for thermal users under normal pressure liquid phase; Our thermal oil heating system adopts Fuji temperature control instruments from Japan, and uses PID self-tuning intelligent temperature control technology. The control accuracy can reach about ± 1 ℃, accurately controlling the temperature range used; The main heating power supply adopts a solid-state module contactless switching circuit, which adapts to frequent switching and has no interference with the power supply network. And has dry burn prevention. According to user requirements, a hot oil cooling system can be designed and added to meet the production process requirements of rapid cooling after heating up;
2. Saving energy and operating costs Low heat conduction oil heating system adopts liquid phase closed circuit circulation, with a difference of 20-30 ℃ between the oil outlet temperature and the oil return temperature, which means that only heating a temperature difference of 20-30 ℃ can reach the operating temperature. At the same time, this equipment does not require water treatment equipment and does not have heat losses such as leakage, emission, dripping, and leakage from steam boilers. It has a high heat utilization rate, saving about 30% energy compared to steam boilers;
Low equipment investment Due to the simplicity of the heat transfer oil heating system, anhydrous processing equipment, and more auxiliary equipment, the boiler withstands low pressure, etc., the investment in the entire system is low;
4. Safety: Since the system only bears pump pressure, the heat transfer oil heating system has no explosion risk, making it safer;
5. The environmental protection effect of the environmentally friendly organic heat carrier heating system is mainly reflected in the small amount of flue gas emissions, without pollution and thermal pollution;
Safety of heat transfer oil heater: The heat transfer oil heater only bears pump pressure, and the heat transfer oil heating system has no explosion risk, making it more safe; The organic heat carrier heater has a very small amount of flue gas emissions, without pollution and thermal pollution, meeting environmental requirements. Heat transfer oil has many advantages such as good thermal stability, good heat transfer performance, low vapor pressure, non-toxic, odorless, and non corrosive to equipment. The heat transfer oil heater uses a computer digital display module to control the temperature, and has the functions of over temperature alarm, low oil level alarm, and over pressure alarm. It is used in industries such as chemical, petroleum, machinery, printing and dyeing, food, shipping, textiles, and film.
Our company has formed a multi-functional control system based on years of scientific research and development, using human-machine interfaces to operate PLC (Siemens and Mitsubishi) programmable controller settings. It fully adopts 4-20 ma transmission multi-channel temperature, pressure, and liquid level height values directly displayed by the touch screen, and supports functions such as timing on/off, automatic oil replenishment, temperature rise history curve, U disk export and printing, and historical alarm record query, making it a leading level in the industry.
