Description

Needle type electrode assembly of direct-current high-pressure disinfection and sterilization air purification equipment

Technical Field

The invention relates to the technical field of air purification equipment, in particular to a needle type electrode assembly of direct-current high-pressure disinfection and sterilization air purification equipment.

Background

In air purification equipment, high-pressure ionization is one of the commonly used technical means, for example, ionization discharge is adopted to prepare ozone, the ozone can be automatically decomposed into oxygen and single oxygen atoms at normal temperature and normal pressure, and the purposes of disinfection, sterilization, fresh keeping and the like are achieved by utilizing the characteristic that the oxygen atoms have stronger oxidation effect on microorganisms; or the electrostatic dust collection and the oil smoke removal are realized by utilizing the electric field generated by the electrodes.

At present, most of common air purification equipment for preparing ozone or electrostatic dust removal by high-voltage ionization adopts a polar plate discharge or tubular polar discharge mode, and the electrodes of the products have the following defects due to structural reasons: (1) the ozone is generated by high-pressure ionization, a large amount of heat is generated and accumulated in a medium between electrodes or a tubular electrode cavity, so that the heat is difficult to dissipate timely and effectively, the temperature between the electrodes is continuously increased, and the accumulated high temperature promotes the reduction of part of the discharged ozone to influence the generation of the ozone, thereby greatly reducing the working efficiency and the energy utilization rate of equipment; (2) under the action of electric field force, particles such as dust, oil smoke and the like in the air are adsorbed and continuously accumulated on the cathode, so that the working efficiency of equipment is influenced, the electrode needs to be detached and cleaned after the equipment runs for a period of time, the electrode structure and the assembly of the conventional product are complex, and a great deal of inconvenience is brought to the future maintenance and cleaning operation, particularly, the tube-pole type dust removal equipment is difficult to clean due to the fact that dust and oil smoke scales in the tube pole are difficult to clean, and even the situation that the electrode is forced to be replaced occurs sometimes. In addition, the slower output of ozone accumulated between the electrodes also accelerates the oxidation of the electrodes to some extent.

Disclosure of Invention

The invention aims to provide a needle type electrode assembly of direct-current high-pressure disinfection and sterilization air purification equipment, which improves air circulation between electrodes, enhances the heat dissipation capacity, simplifies the electrode disassembly and assembly and cleaning operation, overcomes the defects of the existing product, and greatly improves the reliability and the working efficiency of the equipment by a plate type electrode structure.

The technical scheme of the invention is as follows:

comprises a cathode plate which is connected with a power supply unit and is supported by a fixing piece,

and a high voltage electrode plate supported by the fixing member;

the high-voltage electrode plate and the cathode plate are arranged in parallel relatively, and a discharge space with open periphery is formed between the high-voltage electrode plate and the cathode plate;

the high-voltage electrode plate is at least provided with a group of discharge needle groups connected with the power supply unit, and the discharge needle groups are formed by arranging discharge needles with equal length in multiple rows; the tail ends of the discharge needles are fixed on the surface of the plate body of the high-voltage electrode plate, which is opposite to one side of the cathode plate, the free ends of the discharge needles point to the cathode plate, and a corona discharge gap is formed between the free ends of the discharge needles and the plate body of the cathode plate.

Furthermore, the area of the cathode plate is larger than the layout area of the discharge needle group on the high-voltage electrode plate.

Furthermore, the discharge needle group at least consists of two rows of discharge needles.

Furthermore, the discharge needles in each row of the discharge needle group are arranged in a staggered mode.

Furthermore, the high-voltage electrode plate is provided with a vent hole on the side part of the discharge needle group or on the plate body between the discharge needle groups.

Furthermore, the negative plate body is provided with a vent hole, and the vent hole of the negative plate corresponds to the side part of the discharge needle group of the high-voltage electrode plate or between the discharge needle groups.

Furthermore, the fixing piece is a group of insulating support columns, and the high-voltage electrode plate and the cathode plate are connected into an integral structure through the insulating support columns.

Furthermore, the fixing part is an insulating support or a sliding groove which is connected in the air purification equipment box body and is used for supporting and fixing the polar plate (the high-voltage polar plate and/or the negative plate).

The invention has the beneficial effects that: the electrode unit component of the air purification equipment integrates the functions of disinfection, sterilization, fresh keeping, dust removal and the like, has a simple structure, is reliable and convenient to use, and is suitable for air purification in places such as offices, schools, families, restaurants, sports and the like; in the working process of the electrode assembly, the discharge needle group of the high-voltage electrode plate is connected with the power supply unit, a high-voltage electric field is formed between the tip of each discharge needle and the cathode plate, the air is discharged to the cathode plate, and the air (oxygen) flowing between the high-voltage electrode plate and the cathode plate is ionized to generate ozone, so that disinfection, sterilization and the like are realized; because the periphery of the discharge space formed by the high-voltage electrode plate and the cathode plate is open, the high-voltage electrode plate and the cathode plate have better gas circulation and heat dissipation capacity, ozone generated by ionization can quickly flow out from the side part of the discharge space, gas outside the discharge space can also be quickly supplemented between the two electrode plates, and heat generated by discharge can be quickly dissipated so as to control the temperature between the electrode plates. In addition, when ozone is generated by ionization, dust particles or oil smoke and the like in the surrounding air are sucked between the polar plates and adsorbed on the surface of the cathode plate under the action of a high-voltage electric field, so that the aim of removing dust is fulfilled.

Compared with the discharge electrode of the existing purifying equipment (namely, the ozone generator and the dust removal device which adopt the plate-type or tube-type discharge electrode), the ozone generated by the electrode assembly is discharged along with the system and is rapidly output, the heat generated by the discharge is ensured not to be accumulated, the problems of poor heat dissipation between the electrode and the electrode of the traditional product, ozone retention and slow output, ozone reduction and the like are solved, the oxidation of the electrode is reduced, and the working stability and the energy utilization efficiency of the equipment are greatly improved; and the flat plate structure of the cathode plate, the periphery of the discharge space and other characteristics are open, so that the maintenance and cleaning operation of the electrode are facilitated, and the practicability of the product is further enhanced.
