The invention relates to a method and a device adapted for the selective counting of individual respiratory droplets and particles comprising water within ambient air. The method is based on a planar capacitive sensor to which droplets and particles are led with a nozzle, which increases their velocity. Entering the electric field of the capacitive sensor, the respiratory droplets and particles change the sensor's capacitance. Because the respiratory droplets and particles containing water exhibit a notably distinct dielectric constant compared to other airborne particles and the air itself, they are counted in a selective way independently on other particulate matter air pollutants. The alteration in the capacitance is converted into an electrical signal, which is measured by known methods.

This utility model provides a polyurea material spraying and mixing device with a drying function, relating to the technical field of polyurea material spraying equipment. It includes a fixed frame, with an electric telescopic rod fixedly connected inside the frame. By setting up the fixed frame, mixing tank, drying equipment, and mounting plate, the solvent and solution introduced through the guide box are transported to a second storage tank for remixing. A first diaphragm pump operates, driving the mixing tank upwards. At this time, the support slide rod slides upwards from the corresponding support sleeve, assisting the electric telescopic rod in support and facilitating subsequent resetting. This provides a buffering effect for the equipment, thereby extending its service life. Four support feet support the entire device, improving its stability. Timely drying of the sprayed polyurea material reduces secondary pollution from airborne particles and lowers the labor intensity of manual cleaning later.

This utility model discloses a high-efficiency dehumidifier, relating to the field of dehumidifiers. Specifically, it is a high-efficiency dehumidifier comprising a dehumidifier housing, a fan, a compressor, an evaporator, and a condenser. The housing has an air inlet and an air outlet on one side, and a partition in the middle of the housing. The partition is horizontally positioned, and the interior of the housing has a vertically positioned mounting plate. Multiple fans are evenly distributed on the upper middle part of the mounting plate. This utility model solves many limitations of existing dehumidifiers in practical use. Existing dehumidifiers often have simple, straight duct designs with short airflow paths, resulting in insufficient contact with core components such as the evaporator and condenser, leading to low dehumidification efficiency. Furthermore, the air inlet structure lacks effective air guidance and pre-filtration design, allowing airborne particles to directly enter the machine, affecting dehumidification performance and accelerating component wear.

This utility model belongs to the technical field of coking operation in tank furnaces, and discloses an air barrier device for coking operation in large-capacity tank furnaces. It includes a coking baffle, a coking baffle bracket installed on one side of the baffle, and a telescopic rod installed on the side of the bracket away from the baffle. This utility model allows the coking baffle to completely cover the area to be cleaned, forming a physical barrier and effectively preventing external air from entering the furnace. The telescopic rod, by adjusting its length, meets diverse coking needs. The coking baffle bracket, as a component connecting the baffle and the telescopic rod, can withstand mechanical and thermal stresses under high-temperature conditions. This device effectively blocks the entry of external air, preventing the molten glass in the large-capacity tank furnace from being contaminated by external air and airborne particles, ensuring the quality of the substrate glass and greatly reducing the possibility of producing defective substrate glass.

This utility model relates to the technical field of dust removal equipment, specifically to a wet dust collector, including a polishing machine and a washable dust removal mechanism. The washable dust removal mechanism includes an oil collection tank, a spray chamber, a wet tower, two induced draft fans, a sedimentation net, and an electrical control system. The wet tower includes a sprayer, multiple atomizing nozzles, and two water curtain plates. When using the dust collector, the polishing machine, the two induced draft fans, and the sprayer are started. The particles generated by the polishing machine are attracted by the two induced draft fans and enter the spray chamber. Under the action of the sprayer, the multiple atomizing nozzles spray water mist, which humidifies the airborne particles and causes them to fall to the bottom of the spray chamber. The water sprayed by the sprayer forms a water curtain under the action of the two water curtain plates, cleaning the spray chamber. The water flow carries the particles out of the spray chamber and into the sedimentation net, where the particles are intercepted. The water flow can then be reused, achieving the effect of long-term normal operation of the dust collector.

A filter module serves to separate, in particular, sticky and dry paint and / or adhesive overspray, sanding dust, etc., as well as to retain dust or other airborne particles. The filter module comprises two or more interconnected filter plates that serve to hold a filter fleece 14. An edge protector serves to tension the filter fleece 14 within the filter plates 1-4. The edge protector and the filter fleece 14 are bonded to each other, at least partially, by adhesive.

An apparatus (10) for sampling suspended particles, comprising a nozzle (1) used to generate a mist jet (20) containing gas and liquid droplets of varying sizes. The mist jet (20) is formed by the nozzle such that particles present in the surrounding air are drawn into the jet and coalesce with the liquid droplets within it. A sample collection surface (30) is located opposite and separated from the nozzle outlet. Preferably, the sample collection surface is sloped so that the liquid sample is gravity-fed from the collection surface into a vial or other liquid sample container. Within the mist jet and on the sample collection surface, the liquid droplets coalesce to form larger droplets that can be collected in the liquid sample container (32).
