The utility model provides a water ion generator. The water ion generator comprises a semiconductor refrigerator; the dielectric barrier discharge plasma generator covers the cold end face of the semiconductor cooler, the dielectric barrier discharge plasma generator comprises a discharge upper polar plate, a discharge lower polar plate and a dielectric layer between the discharge upper electrode and the discharge lower electrode, the discharge upper polar plate is a patterned electrode, and the discharge lower polar plate is a patterned electrode. The dielectric layer is exposed and is used for collecting condensed water condensed on the cold end surface and exciting the condensed water into water ions. Due to the adoption of the plane structure design, the discharge area is greatly increased, and a traditional point-shaped area of needle tip discharge is changed into a large-area plane area, so that the positive and negative ion generation efficiency is remarkably improved. Meanwhile, the condensation area of the plane structure is far larger than that of the needle point structure, more condensate water can be collected, and the generation amount of water ions is further increased.

This utility model relates to the field of pipeline device technology and discloses a porous pipeline device for sewage aeration. The porous pipeline device includes a sewage tank, on which a decontamination mechanism is installed. The decontamination mechanism includes an air inlet pipe. To improve the filtration effect of the aeration gas, this porous pipeline device for sewage aeration incorporates a decontamination mechanism. When the gas enters the gas collection box from the air inlet pipe, it undergoes further fine filtration with the help of coarse and dense filter plates. Multiple sets of branch pipes increase the distribution density of the exhaust ports and the gas discharge area. Simultaneously, the filter screen breaks the gas into multiple small bubbles, allowing the gas to contact the sewage over a wider range and at more angles, thereby improving the gas-liquid mixing effect. Furthermore, the conical design of the conical shroud prevents impurities in the water from adhering and accumulating near the top of the branch pipes; instead, they slide off along the slope under the action of water flow, ensuring stable operation of the device.

The present application relates to air purification equipment technical field, disclose a kind of carbon fiber spiral electrode, plasma generating device and air purifier.The carbon fiber spiral electrode includes: spiral electrode, including carbon fiber bundle and the burr suppression structure being wound or wrapped in the outer periphery of carbon fiber bundle, spiral electrode is suitable for grounding;Inner electrode, inner electrode is wrapped with insulating layer, spiral electrode is spirally wound in the outer periphery of insulating layer, inner electrode is suitable for connecting alternating current power supply high voltage end.The carbon fiber spiral electrode of the present application can not only constrain carbon fiber bundle into bundle, effectively reduce the width of carbon fiber bundle, avoid carbon fiber bundle to be laid in insulating layer outside to lead to occupy the discharge area of carbon fiber spiral electrode, can effectively improve discharge effect.At the same time, since the burr suppression structure is wound in the outer periphery of carbon fiber bundle, it also will not pass through the surface of insulating layer to lead to occupy the discharge area of carbon fiber spiral electrode, which further improves the discharge effect of carbon fiber spiral electrode.
