Description

An electrostatic oil fume purifier

technical field

The utility model technology relates to an oil fume purification device in the catering industry, in particular to an electric field structure of an electrostatic oil fume purification device.

Background technique

Existing lampblack purifiers include: mechanical filter type, water curtain spray type, electrostatic type and electrostatic mechanical composite type, wherein the treatment effect of electrostatic type is better. The electric field structure of the currently known electrostatic lampblack purifier is a dihedral plate structure, and the two faces of the electrode are parallel to the flow direction of the flue gas, which is not only large in size and heavy in weight, but also has an unsatisfactory dust collection effect.

Contents of the invention

The purpose of the utility model is to provide an electrostatic oil fume purifier, which provides high-voltage and sub-high-voltage two-stage electric fields, increases the effective dust collection area of the electric field, and reduces the weight of the product.

The utility model is realized through the following technical solutions: it includes a casing, an air inlet, an air outlet electric field device, and a power supply box, wherein the electric field part is composed of two groups of high-voltage electric fields and one group of secondary high-voltage electric fields, and each group of high-voltage electric fields is composed of a support plate , a positive pole support rod, a positive pole electrode plate, a negative pole support pole, a negative pole electrode wire, an electrode wire adjustment screw and an insulator. The support plate is composed of two parallel metal plates, which are installed on the shell, and the direction is parallel to the direction of air inlet and outlet; the positive electrode plate is composed of a group of parallel metal plates, which are installed on the two support plates. Between, and the direction of the two surfaces of the metal electrode plate and the direction of the support plate are inclined at a certain angle, the angle range is 10°-25°; the negative electrode is composed of a group of metal wires, installed between the positive metal plates and connected to the two The distance between the positive metal plates is equal, one end of the metal wire is fixed on the negative pole support rod, and the other end is fixed on the adjustment screw installed on the negative pole support rod, and the tension degree of the metal wire can be adjusted by the screw. The inclination directions of the two sets of high-voltage electric field electrode plates are opposite, so that the flow velocity of the fume gas can be reduced and a turbulent flow can be formed. The sub-high voltage electric field is composed of a group of metal plates parallel to each other, in which the positive and negative electrodes are separated by an insulator. The side part of the housing is a power supply box, which can provide a high-voltage power supply of 15 kV and an adjustable sub-high voltage power supply of 1-5 kV respectively by a high-voltage power generator.

By adopting the above technical scheme, the fume gas is purified by one set of secondary high-voltage electric fields and two sets of high-voltage electric fields respectively when passing through the oil fume purifier. The arrangement density of the plates in the sub-high voltage electric field is relatively high, which can fully absorb the large-diameter soot particles. Because the positive plate used in the high-voltage electric field is inclined at a certain angle relative to the flow direction of the fume gas, the dust collection area of the electric field increases, and the fume gas is blocked when it passes through, changing the flow direction and reducing the flow velocity. The gas in the electric field Agitation forms turbulent flow, and the residence time in the electric field is prolonged, thereby further improving the purification efficiency. The negative electrode uses metal wire as the carrier, which greatly reduces the weight of the whole machine. Because one end of the metal wire adopts an adjusting screw to adjust its tension degree, the tension degree of the metal wire can be kept at an optimum level. If the metal wire is installed too loosely, vibration will occur, which will not only generate noise and arcing, but also reduce the life of the metal wire due to fatigue strength under high-frequency vibration; if it is too tight, the metal wire will break and cause a short circuit. The high-voltage power generator in the power supply part adopts a high-voltage package tap method and is connected with an adjustable resistor, and the voltage division can generate a high-voltage power supply and an adjustable sub-high-voltage power supply respectively. Due to the tap method, and the voltage of the sub-high voltage power supply is adjustable, the most suitable output voltage can be selected according to different usage conditions (such as oil fume particle size, working environment, usage time, etc.). The adsorption will reduce the field strength and affect the purification effect. At this time, the voltage can be appropriately increased to ensure that the equipment is always in the best state.
