COL

Cyclone is a purifier of media containing foreign inclusions, used in industry for purification of both gas-containing phases and liquids. Dust collectors of cyclone type, with the help of which gases are cleaned from solid suspensions, make up a fairly large group among all types of dust collecting equipment, widely used in most industries.

Cyclones of the COL class are widely demanded today for cleaning the air environment from suspended grain dust, all kinds of debris larger than 125 microns, husks, weeds, sawdust, etc. They are specially designed as cleaning equipment, without which it is impossible to do in the agricultural industry – in the flour milling industry, at elevators, feed mills, granaries, grain dryers, etc. Cyclones of the DFC are widely popularized for cleaning the air mass coming from pneumatic or aspiration networks. Often cyclones of this series can be seen in the woodworking industry. It is advisable to use such equipment to collect dust from air masses heated to 50 ° C.

Dust collector units are installed both in buildings and in open space. The equipment is strictly forbidden to use for the collection of fine fibers and sticky dust.

Design features and raw materials

All elements of the cyclone of the COL series are made of consumable material – carbon steel or stainless steel. The design of cyclones of the COL class is based on the basis of external and internal concentric cylinders. It also includes an exhaust pipe, regulator, cone, cap or umbrella. The productivity of the DCE device directly depends on the size – this figure can increase from 1000 to 18000 m3/hour depending on the diameter, starting from 453 and ending with one thousand nine hundred thirty-two millimeters, and height – 1503 – 6341. At the same time, high efficiency is obtained – the efficiency of trapping, for example, grain dust, in such devices is between 95-98 percent. The peculiarity of the design of the centrifugal separator units is the presence of an anti-suction cone device, which serves to regulate the pressure in the inlet pipe of the unit working on the discharge. In the case when the cyclone is installed in the open air after the fan, working on the discharge, it is necessary to use a special umbrella to protect against precipitation. When the dust collector is installed before the fan, working on discharge, in order to effectively reduce the loads on the fan and minimize the hydraulic resistance of the equipment system as a whole, a snail-spinner is required.

These cyclones, like their “brothers”, are also made with left/right rotation of the passing flow. Left – against the movement of the clock hand, if you look from the side of the exhaust pipe, right – in the direction of its movement.

Specifics of the cyclone operation

Air enters the dust collecting unit at a speed of 15-18 m/s. The cylindrical compartment is the main working part of the DSC unit. The very operation of capturing foreign particles in the cyclones of the DPS is carried out due to the influence of centrifugal force on them, which appears when the flow of contaminated air masses is tangentially fed into the body of the device at sufficiently high speeds. In this case, the process of rejecting the suspension to the walls of the unit occurs. After the air leaves the annular gap located between the body and the cyclone inlet pipe, its speed slows down. The direction of movement of gas flows changes exactly 180 degrees only in the center of the dust collector. Here the inertial forces come into play, due to which the foreign air content is separated. Dust particles move to the bottom of the housing, and from there to a special storage hopper, which must be continuously or periodically cleaned of them. In the latter case, the upper level of the accumulated contents should be 400 millimeters below the plane of its lid. Practically clean air is emitted through the exhaust pipe into the atmosphere. On the line of unloading the captured secondary product from the hopper, it is necessary to install a sluice feeder/valve with a flashing valve, which prevents the appearance of air suction during the operation of the cyclone of the CLC class under vacuum or the leakage of contaminated gas – under the pressure created by the fan.

According to the degree of purification, the series of cyclones COL belongs to the fourth class of dust cleaners according to GOST 12.2.043-80. Usually these cyclones are used as the first stage of air purification.

At the time of installation of the cyclone unit, as well as during its maintenance, it is necessary to pay strict attention to both the sealing of the system, including the supply and discharge air ducts, and, accordingly, the quality of the surfaces inside it, which are in direct contact with the purified air flow.

When operating such cyclones, safety measures must be strictly observed, because contact with heated external surfaces of the devices, as well as with the hottest gas, dust and ash, can lead to unpleasant consequences – severe burns. To prevent them, the hot surfaces of the system must be properly insulated.

It is very profitable to buy today cyclones in the online store Ventilator. The model range is reliable in operation. It is distinguished by both high technical characteristics and a short payback period. Professional managers will advise you how to choose and buy the right copy of the cyclone of the DPC, will give comprehensive information on how to properly install it and provide maintenance during operation. The application for the desired cyclone will always be executed exactly on time.
