Background Technology

[0002] During the fuel supply process, fuel needs to pass through the daily fuel tank, diesel tank, and diesel engine before entering the catalytic converter for dechlorination and denitrification. Currently, this is done manually with a low degree of automation. Incomplete fuel combustion and exhaust emissions negatively impact environmental protection to some extent. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a fuel supply unit device that is highly automated, environmentally friendly, reliable, and capable of continuous production.

[0005] An electric heater is installed on the fuel inlet pipe to heat the fuel by converting electrical energy into heat energy.

[0006] The electric heater is connected to the mixing tank, and an automatic backwash filter and a plate cooler are sequentially installed on the oil supply pipeline connecting the electric heater and the mixing tank; the automatic backwash filter is used to remove impurities from the fuel entering the oil supply pipeline; the plate cooler is used to cool the fuel.

[0007] The steam heater is also connected to the oil mixing tank and is located before the automatic backwash filter;

[0008] The plate cooler is connected to the supply pump; a viscometer is installed between the plate cooler and the supply pump to monitor fuel viscosity.

[0009] The supply pump is connected to the mixing tank; the mixing tank is also connected to the dual filter via a booster pump; a flow meter is installed on the fuel supply pipeline between the booster pump and the mixing tank to monitor the fuel flow rate.

[0010] A bypass is provided after the supply pump;

[0012] The pressure control system is used to control the pressure of the fuel supply unit.

[0013] Furthermore, an expansion tank is also installed on the pipeline between the automatic backwash filter and the oil mixing tank.

[0014] The electric heater input is equipped with a directional valve to switch between light and heavy oil.

[0015] The electric heater of this invention converts electrical energy into heat energy to heat fuel and prevent the fuel from waxing at low temperatures. When the fuel temperature is too low, the electric heater will activate to heat the fuel, maintaining its proper fluidity and ensuring normal fuel supply to the fuel system.

[0016] A fuel supply unit device of the present invention provides a fuel supply method, characterized in that:

[0017] The supply pump pumps fuel from the fuel tank and heats it as needed using an electric heater or a steam heater.

[0018] After being treated by an electric heater, the fuel enters an automatic backwash filter for filtration. The plate cooler cools the fuel as needed, and then the fuel is fed into the mixing tank by a supply pump. The mixing tank receives the fuel from the fuel tank and holds the fuel.

[0019] After being heated or cooled, the fuel enters the viscometer inlet. The viscometer monitors the current concentration of the fuel in real time and feeds the measured value back to the electronic control system.

[0020] The fuel in the mixing tank is pressurized a second time by the fuel supply booster pump, and the pressure control system regulates and controls the outlet pressure of the fuel pump; the fuel flow rate and flow data are collected by the flow meter and fed back to the electronic control system;

[0021] The mixture from the mixing tank is then filtered twice by a dual filter before being fed into the diesel engine.

[0022] The beneficial effects of this invention are as follows:

[0023] The device of this invention has a simple structure and significant effects. By heating the fuel, it improves the fuel's fluidity and combustibility, thereby increasing its calorific value, reducing exhaust emissions, improving fuel utilization, and lowering operating costs. Simultaneously, the heater prevents the fuel from freezing in low-temperature environments, ensuring the normal operation of the fuel system. Attached Figure Description
