Leading brand of electrostatic precipitator for commercial kitchen ventilation.

Scope of application of portable gas purifier

Portable purifier the applicable range of movable smoke purifier under normal circumstances, the air velocity emperor take 4 of the tower sections. Below 0 m/s. If air velocity increases, it must increase the effective height of tower body, so that flue gas stop at tower you have plenty of time, the water spray is easy to achieve full evaporation. Delay for more than 5 s. Effective height depends on the nozzle injection of evaporative cooling tower water droplets evaporation time, and evaporation time depends on the size of the droplet size and flue gas heat capacity. Therefore, in order to reduce the height of the evaporative cooling tower, it is necessary to minimize water droplet size, namely the drop diameter of nozzle spray into the requirement is very fine, the fog particles in a short time after contact with high temperature flue gas, absorb all flue gas after the sensible heat of vaporization, and flue gas reheat and form an unsaturated gas. And should be able to adapt to the flue gas heat adjustment without affecting the spray particle size, while maintaining a high water pressure, and require the use of the nozzle have a higher life. Generally can be used with backflow pressure nozzle, the nozzle can check the technical performance of the relevant information. For portable flue gas purifier for mixed gas water medium evaporation cooling tower. Evaporative cooling tower structure forms the basic analogous to spray type filter medium evaporation cooling tower for cooling water. The difference is that it USES the gas liquid two phase flow nozzles to strengthen the capacity of the spray nozzle, namely using pressure steam or compressed air can be mixed with water, water droplets diameters of nozzle spray into the finer, better cooling effect. And contact with high temperature flue gas can shorten the time, the section of the inside of the evaporation cooling tower air velocity can improve appropriately, it can reduce the height of the cooling tower, is advantageous for the equipment layout, etc. Portable gas purifier the evaporative cooling tower has a wide applicable scope, can also be used for converter gas dry purification system and other occasions of high temperature flue gas cooling, and can be used with electrostatic precipitator. For electric furnace dry dust collector system, evaporative cooling tower to reduce the flue gas temperature must not be below the saturation temperature of the flue gas, the dew point of flue gas temperature, lest appear dewing phenomenon and affect the normal operation of the system. For safety consideration, when the flue gas inlet temperature below 150 ℃, the nozzle should stop work; After cooling flue gas temperature and demands should be 30 ~ 50 ℃ above the dew point of flue gas humidity; Export flue gas relative humidity below 30%.

What is the difference between single pass and double pass kitchen electrostatic precipitator?

Single-pass and double-pass DR. AIRE commercial kitchen electrostatic precipitators (ESPs) differ mainly in configuration, removal efficiency, and application suitability.In a single-pass ESP, exhaust air passes through one ionizing and collection stage only once. The design is simple and compact, typically achieving 90%–95% grease and particulate removal efficiency under optimal airflow conditions. It is best suited for high-level rooftop discharges or locations with moderate regulatory requirements, offering lower cost and easier installation.In contrast, a double-pass ESP routes air sequentially through two stages in series. This configuration significantly boosts efficiency to 98%–99.9%, minimizing pollutant breakthrough even under heavy grease loads. Double-pass systems are ideal for low-level exhaust, strict environmental regulations, and sensitive urban or mixed-use buildings.While double-pass units incur higher pressure drop, larger space needs, and increased maintenance, they provide superior long-term performance and compliance. Single-pass systems are more economical for standard applications.In summary, single-pass ESPs are preferred for cost-sensitive, less critical installations, whereas double-pass ESPs are recommended when maximum air purification is essential. Selection should consider airflow volume, contaminant load, and local codes.
How Does a Kitchen Electrostatic Precipitator Work?

What is the Efficiency of a Kitchen ESP Filter?

In the bustling environment of a commercial kitchen, managing cooking exhaust is a critical challenge. The Electrostatic Precipitator (ESP) has emerged as the industry standard for tackling this issue. But when it comes to evaluating the performance of an ESP filter, what exactly does "efficiency" mean, and what numbers can operators realistically expect?
