Description

Technical Field

[0001] The utility model relates to the field of purifiers, and more specifically to a palm oil high-voltage electrostatic purifier. Background Art

[0002] The purification principle of the electrostatic collector is to use the strong electric field formed between the high-voltage discharge electrode and the grounding electrode to give the palm oil smoke particles in the dirty air a certain amount of negative charge, and then the oil droplet particles are adsorbed onto the two electrodes through the action of the high-voltage strong electric field. Ultimately, the purpose of removing palm oil smoke pollutants in the dirty air is achieved. Since palm oil has a low melting point of about 35-40 degrees Celsius, it is solid at room temperature. As a result, the electrostatic collector is filled with palm oil in just a few days. Therefore, the main devices currently used in the field of palm oil purifiers in China generally have the problems of short service life and low purification effect, and therefore need to be cleaned regularly. However, this practical palm oil purifier can achieve the effect of alternating purification and cleaning, greatly improving the purification efficiency and extending the working cycle.

DETAILED DESCRIPTION

[0030] The present invention is described in detail below in combination with specific embodiments with reference to the accompanying drawings.

[0031] A palm oil high-voltage electrostatic purifier comprises a heat preservation chamber, an electrostatic collection system, a hot air system, a heater, a fan, and an electrical control box. The heat preservation chamber is a single unit with reserved openings on the left and right sides for pipes to enter and exit, and a door at the front for access. The electrostatic collection system, hot air system, heater, fan, and electrical control box are all housed within the heat preservation chamber.

[0032] The electrostatic capture system includes an electrostatic collector, an air inlet duct, an air outlet duct, and a damper. The electrostatic capture system is a two-stage system divided into two subsystems, upper and lower. The ventilation dampers are located in the air inlet duct and the air outlet duct, two each, at either end of the upper and lower electrostatic capture subsystems. When the smoke exhaust system is operating, the PLC automatic control system first opens the first ventilation damper 3 and the second ventilation damper 4, and closes the third ventilation damper 5 and the fourth ventilation damper 6, allowing the smoke to sequentially pass through the first electrostatic collector 7 and the second electrostatic collector 8 of the upper subsystem. After undergoing secondary electrostatic capture and decomposition, the smoke finally enters the fan for high-pressure exhaust. After the first and second electrostatic collectors 7 and 8 have operated for 48 hours, the system automatically closes the first and second ventilation dampers 3 and 4 and opens the third and fourth ventilation dampers 5 and 4. The smoke then enters the third and fourth electrostatic collectors 9 and 10 of the lower subsystem, where it is purified and then discharged through the fan for high-pressure exhaust.

[0033] The electrostatic collector includes a housing, an air inlet, an air outlet, a hot air inlet, an electrical box, an electric field, and an oil drain. The air inlet and outlet are located on the left and right sides of the electrostatic collector and have air outlet flanges for connecting to ventilation ducts. The hot air inlet is located on the top of the housing, directly above the electric field. There are two rows of air inlets, each with five air inlets, and the air inlets are evenly spaced to ensure uniform heating of the electric field. Each electrostatic collector in the electric field has four, and the housing is divided into two layers, so there are two upper and lower electric fields. The electrical box has four corresponding discharge positions for the electric field. The power supply inside the electrical box can convert the 220V voltage into high voltage and transmit it to the electric field. The oil drain is located at the bottom of the housing and can discharge the palm oil into a designated container to ensure the cleanliness of the interior of the electrostatic collector housing.

[0034] The hot air system is located on the right side of the electrostatic collector and is composed of a hot air blower, a hot air valve, a hot air duct and a blowing pipe. The hot air blower provides hot air to the hot air duct; the hot air duct is divided into two-level ducts, which respectively provide hot air to the upper and lower subsystems of the electrostatic collector system. The hot air valve is at the two-level duct and is controlled by the PLC automatic control system in the electrical control box. When the upper electrostatic collector stops working, the hot air valve 21 is opened and the hot air valve 20 is closed to supply hot air to the upper electrostatic collector. When the lower electrostatic collector stops working, the hot air valve 20 is opened and the hot air valve 21 is closed to supply hot air to the lower electrostatic collector for melting the palm oil attached to the electric field. The heating time is about 3 hours and the palm oil will be completely melted. The hot air system also switches between the two hot air valves through the PLC automatic control system of the electrical control box. While alternately heating the upper and lower electrostatic collection subsystems, it does not affect the purification of the flue gas, thereby achieving simultaneous purification and cleaning.

[0035] The heater is located on the right side of the fan heater and provides heat for the entire insulation room.

[0036] The fan is located at the rear end of the electrostatic collector, and draws air containing palm oil into the electrostatic collection system, while discharging the purified air, thereby preventing the fan blades from being covered with thick palm oil.

[0037] The electric control box is located on the right side of the box inside the insulation room. There is a PLC control system inside the electric control box for controlling the electrostatic capture system, ventilation damper, hot air system, hot air damper, heater and fan.

[0038] The present invention utilizes a hot air system to alternately clean the electrostatic capture system to ensure that the electrostatic capture system can operate continuously and stably for a long time. This method is not limited by the structure of the electrostatic capture system and the number of electrostatic collectors.
