一种直流高压消毒灭菌空气净化设备的针式电极组件A needle electrode assembly for direct current high pressure sterilization and sterilization air purification equipment

技术领域technical field

本发明涉及空气净化设备技术领域,具体地说是一种直流高压消毒灭菌空气净化设备的针式电极组件。The invention relates to the technical field of air purification equipment, in particular to a needle electrode assembly of a direct current high pressure sterilization and sterilization air purification equipment.

背景技术Background technique

在空气净化的设备中,高压电离是常用的技术手段之一,例如采用电离放电制备臭氧,在常温常压下臭氧可自行分解为氧气和单个氧原子,利用氧原子对微生物具有较强氧化作用的特点,达到消毒、灭菌、保鲜等目的;或者利用电极产生的电场实现静电除尘、去除油烟。In air purification equipment, high-voltage ionization is one of the commonly used technical means. For example, ionization discharge is used to prepare ozone. At normal temperature and pressure, ozone can be decomposed into oxygen and a single oxygen atom by itself, and the use of oxygen atoms has a strong oxidizing effect on microorganisms. It can achieve the purpose of disinfection, sterilization and preservation; or use the electric field generated by the electrode to realize electrostatic dust removal and remove oil fume.

目前常见的利用高压电离制备臭氧或静电除尘的空气净化设备,大多采用极板放电或管极式放电的方式,这类产品的电极由于结构原因存在有以下缺陷:(1)高压电离生成臭氧的同时产生大量的热,积蓄在电极间的介质或管式电极腔内,造成热量难以及时、有效的散失,电极间温度持续升高,而聚积的高温促使来不及排出的部分臭氧还原,影响臭氧的生成,大大降低了设备的工作效率及能源利用率;(2)在电场力作用下,空气中的灰尘、油烟等颗粒吸附并不断积聚在阴极上,影响设备的工作效率,因此设备运行一段时间后需要将电极拆下清洗,而现有产品的电极结构及装配复杂,给日后维护和清理操作带来诸多不便,尤其是管极式的除尘设备,因管极内灰尘、油烟结垢难以清理,甚至被迫更换电极的情况时有发生。此外,积聚在电极间的臭氧输出较慢也在一定程度加快了电极的氧化。At present, the common air purification equipment that uses high-voltage ionization to prepare ozone or electrostatic dust removal mostly adopts the method of plate discharge or tube discharge. The electrodes of these products have the following defects due to structural reasons: (1) High-voltage ionization generates ozone At the same time, a large amount of heat is generated, which is accumulated in the medium between the electrodes or in the tubular electrode cavity, which makes it difficult to dissipate the heat in a timely and effective manner, and the temperature between the electrodes continues to rise. (2) Under the action of electric field, dust, oil fume and other particles in the air are adsorbed and continuously accumulated on the cathode, which affects the working efficiency of the equipment, so the equipment runs for a period of time Afterwards, the electrode needs to be removed for cleaning, and the electrode structure and assembly of the existing products are complicated, which brings a lot of inconvenience to future maintenance and cleaning operations, especially the tube-type dust removal equipment, which is difficult to clean due to the dust and oil fume in the tube. , and even forced replacement of electrodes occurs from time to time. In addition, the slower output of ozone accumulated between the electrodes also accelerated the oxidation of the electrodes to some extent.
