Ventilation engineering companies to undertake various tin, tin ventilation engineering Hangzhou, Shaoxing tin ventilation engineering, Hangzhou fume purification project, Hangzhou, engineering, installation and design of ventilation, fire smoke hotel kitchen project, Hangzhou, central air-conditioning duct installation and other train services. Undertake various ventilation dust purification, large central air-conditioning, kitchen exhaust systems, fire smoke and other projects. Providing spiral duct, a total of flange plate duct and elbow fittings customized services. Venturi tube dust: the diversion device (nebulizer), Venturi tube and a dehydrator. Principle and the advantages and disadvantages of ESP: ESP is the use of electricity generated by the electrostatic field so that the dust particles separated from the gas stream device. Advantages: Suitable for particulate control new wind ventilators, for 1 ~ 2μm particle size of dust particles plug-new wind ventilators, efficiency up to 98% to 99%, the lower the resistance of ESP, only 100 ~ 200Pa, Gas can handle high temperature (400 ℃ or less), for large projects a wall-mounted fresh air ventilator, the greater the amount of gas processing, its economic effect is more obvious. Disadvantages: large equipment, large area, multi-residential consumption of steel with the new wind ventilators, a large investment. More complex structure, manufacture, installation of high precision, the specific resistance of the dust has certain requirements. ESP power supply device, comprising: a step-up transformer, rectifier, control devices. Which new wind ventilators | Tonglu new wind ventilators | Xingda - fresh air ventilators supplied by Hangzhou Xingda ventilation equipment.
