[029] The dust catcher is an advanced spray droplets generator using rotary atomization for the spraying of a wide range of liquids for humidification, cooling, dust control, cold fogging and other processes. The humidifier uses a unique rotating woven wire gauze cylinder that produces spray droplets with a narrow spectrum of sizes over a wide range of flow rates from a few milliliters/minutes to 10 liters/minutes. The narrow droplet spectrum ensures that the maximum amount of liquid is sprayed as droplets of the optimum size and minimizes wastage or contamination from excessively small or large droplets. As the spray droplets size is determined by the humidifier rotational speed, the variable speed drive can be adjustable to give the optimum droplet size for a wide range of applications. The direct drive Industrial humidifier are designed for use with water, solutions of deodorizing chemicals and similar liquids in a wide range of applications.
[030] Referring now to Figures 1-4, the present invention provides a dust catcher that includes a blower comprising an impeller and a high-speed rotating mechanism that produces thrust in order to travel water mist particles; a humidifier comprises a special high speed three phase induction motor with a water intake system and a rotating mesh ring provided with a mesh cover; a pump provided with a water inlet line and a solenoid valve; an electrical panel comprises AC VFD drives for humidifier and blower separately; an AC - DC converter for DC operations, and an enclosure made up of sheet metal; and a rotating mechanism comprises a worm gear gearbox and DC geared motor which is mounted on a worm gear gearbox arrangement (slew drive).
[031] The blower consists of a high-performance impeller and a three-phase inductive motor mechanism that can produce enough thrust so that the water mist particles can travel up to the distance of 10 – 20 meters. with adjustable motor speed control so that the coverage area can be adjustable. With lower rpms the coverage area in standing position increases than in full rpm. At full rpm it can reach maximum distance with narrow coverage. The maximum rpm of blower motor is around 1450 rpm. At this rpm the thrust created will help the mist particles to reach up to 20 meters.
[032] The humidifier is an arrangement consist of a special high speed three phase induction motor with a water intake system and a rotating mesh ring which in combination capable of producing mist particles of size nearby or less than 10 microns. To reach this size of water mist particles the special high speed three phase induction motor has to attain a speed of around 12,000 rpm and this is done with the help of a VFD AC drive. The working frequency of the motor is up to 180 Hz. The water inlet pressure is maximum 2 bar with discharge of 500ml – 10 liter per min. The mesh ring rotates at speed of 12,000 rpm which breaks the water particles to mist form of nearby or less than 10 microns.
[033] The rotating mechanism is a combination of a worm gear gearbox and DC geared motor. The system is mounted on the worm gear gearbox arrangement (slew drive) and the DC geared motor is directly coupled with it. When the DC geared motor rotates it first it rotates the gearbox thus producing a horizontal rotating motion of unit. If we change the polarity of DC geared motor the direction of de geared motor changes which also changes the direction of unit.
[034] The electrical panel is consisting of two number of AC VFD drives for humidifier and blower. The operating voltage of the electrical panel is three phase 415v, 50hz. The enclosure is made up of sheet metal with IP rating of IP65. The approximate power requirement of the system is 1 KW.
