Technical requirements for bag frame of bag dust collector


Bag frame of bag dust collector
Have sufficient strength, stiffness, verticality and dimensional accuracy to prevent damage Pressure deformation, damage during transportation, contact with each other after the filter bags are installed in the dust collector, and bag frame friction due to difficulty in bagging


Bag frame of bag dust collector
Surface Anti-corrosion treatment must be carried out. Plastic spray painting or electroplating can be used. The anti-corrosion treatment agent used for high temperature should meet the requirements of high temperature. The contact surface between the bag frame and the filter bag of the bag dust collector should be smooth, and no welding scars, unevenness and burrs are allowed.

Basis for selection of bag frame of bag dust collector

Consider resistance loss and structural form, minimize power consumption, and pay attention to the convenience of future maintenance.

The smallest dust particles that can be captured by the bag frame of the bag dust collector should be equal to or slightly smaller than the dust particle size of the gas being processed.

The airtightness of the bag frame of the bag dust collector should be paid attention to, especially when operating under negative pressure, the reliability of the discharge air locking device should be paid more attention to.

Safety and explosion-proof valves are often added to the inlet pipes to prevent explosions of flammable and explosive dust.

When the dust viscosity is small, the larger the diameter of the cyclone, the greater the maximum allowable dust mass concentration.

The amount of purified gas in the bag frame of the bag dust collector should be consistent with the amount of dust-containing gas actually processed. When choosing the diameter of the dust bag cage, it should be as small as possible. If the air volume required to pass through is large, several small-diameter cyclones can be used in parallel. If the air volume matches the bag frame of the bag dust collector, it is better to choose a multi-tube dust collector.

The wind speed at the dust bag cage inlet should be maintained at. If the wind speed is too low, the dust removal efficiency will decrease. If the wind speed is too high, the dust removal efficiency will decrease. The improvement in dust removal efficiency is not obvious, but the resistance loss increases and the power consumption increases.

When the temperature of the dust-containing gas is very high, attention should be paid to thermal insulation to prevent moisture from condensing in the bag frame of the bag dust collector. If the dust does not absorb moisture, the dew point is ~

, the temperature of the bag frame of the bag dust collector should be at least higher

If the dust has strong water absorption, such as gypsum, etc., the dew point is ~

, the temperature of the bag frame of the bag dust collector should be higher than the dew point temperature~




Silicone anti-corrosion frame
/> It is a high-end dust removal frame made of high-strength carbon steel that is welded and formed in one step by a multi-head high-frequency automatic spot welding machine and subjected to silicone post-processing.
Trapezoidal skeleton
With a flat structure, the longitudinal bars and anti-bracing rings of the trapezoidal skeleton are evenly distributed and have sufficient strength to prevent damage and deformation. In order to ensure the strength of the steel wires and improve the appearance quality, we use elements When the steel is drawn (drawn and then assembled on the butt-welded tire, it must be ground to meet the technical requirements.
Spring frame
An essential supporting product for the external filter dust collector, which is divided into venturi tube and non-tube type. There are two types of venturi tubes, which have a certain degree of flexibility. Because the dust collector is limited by the indoor space, there is no certain space at the top of the dust collector to replace the dust collector frame, so the spring frame or (plug-in) multi-section type is used in the design. Dust removal frame.
Inner star angle dust removal frame
It is more effective when the dust collector bag is deflated, and the dust removal bag is blown up and expanded to become thicker. When the air flow is certain, the movement is larger and the dust cleaning effect is better.
