Venturi Scrubber Dust Collector Centrifugal Fan by Xianrun Blower

The venturi scrubber is mainly composed of venturi tube (shrink tube, throat pipe, expanding tube) and the cyclone separator, centrifugal fan.

Custom heavy Duty Industry Fan from China Supplier

Working principle of venturi scrubber dust collector: dusty gas enters into the shrink tube, then the flow speed increases gradually along the pipe; water or other liquid are ejected by the throat pipe, struck by high-speed airflow and atomization; dust particles in the gas contact with liquid drops and lubricate; after entering expanding pipe, the flow speed decreases gradually; the dust particles are bonded to each other; the particles volume increase and easy to remove; then, the gas enters the cyclone separator, due to the centrifugal force, water and dust particles are thrown to the separator wall and outflow cyclone separator; finally, the purified gas is exhausted out by centrifugal fan.

The advantage: simple structure, high dusting efficiency, good cooling effect.
The disadvantage: big resistance, just used for wet-type dust collecting.

Electrostatic Dust Collector Centrifugal Fan by Xianrun Blower

Electrostatic dust collector is a new way of processing small dust scattered points. This electrostatic dust collector uses the exhaust duct or enclosed hood as counter electrode, which connect high voltage power supply and form electric field.

Industrial Exhaust Fans

When centrifugal fan sends dusty gas to the electric field, the dust under the electric field force, is collected on the cover or wall, after purification, the gas is exhausted out by centrifugal blower.

Coupling Driving FD Fan with High CFM

Ash removal by artificial shaking or falling out self-gravitationally. This dust collector is particularly suitable for scattered dust points of crushing, screening shop and sintering workshop transporting belt, or dust purification for mine tunnel, small boilers.

The electrostatic dust collector has many different models, generally includes bell-type, tube-type, open-type.

Spray Tower Scrubber Centrifugal Fan by Xianrun Blower

Spray Tower Scrubber Working Principle:

In the counter-current spray tower, dusty gas moves upward by centrifugal fan, the droplets by nozzle make downward movement. Because of inertia collision, intercept, cohesion functions between droplets and dust particles, the larger particles are collected by the droplets.

High Temperature Fan For Metallurgical Factory

Spray Tower Scrubber Features:

1. It uses packed tower to purify the waste gas, and is suitable for continuous or intermittent dusty gas discharge.
2. Spray tower scrubber has the features of simple structure, small pressure loss, stable operation, high efficiency, etc.
3. Wide application, and can purify a variety of pollutants and dusty gas.

Custom heavy Duty Industry Fan from China Supplier

Spray Tower Scrubber Application:

In chemical industry, electronics industry, metallurgic industry, electroplating industry, textile factory, food plant, and so on, it can purify and collect acid waste gas, alkaline waste gas, dusty gas in the processing.

Wet-Type Impingement Dust Collector Centrifugal Fan by Xianrun Blower

Impingement wet dust collector is used for high humidity, big discharge, large dust content industrial waste gas, especially suitable to purify the fibrous, non-corrosive, and temperature less than 300 centigrade dusty gas. The impingement wet dust collector has good effect in the dust system of sticky quick lime transportation.

High Temperature Fans for Dust Collecting

The smoke exhausting from boiler by centrifugal fan enters into the dust collector, impacts the water at high speed, most dust particles stay in the water due to the weight increase or sticking to water, this is impingement stage.

At this time, because of the gas movement, the water form a parabola-shape drop, spray, and bubble area, then the dusty gas is purified further in this area, and this is a water bath stage.

What is more, when the high temperature gas enters into the dust collector, the water and gas will form water spray, the dust particles change flow direction, further purification when moving forward, this stage is nebulization dust collector.

Through the above three ways purification, clean gas from dust collector flow to the chimney.

Gravitational Dust Collector Centrifugal Fan by Xianrun Blower

Dust removal principle: the centrifugal fans of gravitational dust collector reduce gas speed and change flow direction suddenly; larger dust particles separate from gas under the function of gravity and inertia force; settle to the dust collector cone bottom.

Industrial Exhaust Fans

The gravitational dust collector belongs to the coarse dust removal. There is intercepter valve in gravity precipitator upper part, ash discharging gear in gravity precipitator bottom part. Gravity dust collector is according to dust gravity sedimentation, to separate dust from the dirty gas.

Custom heavy Duty Industry Fan from China Supplier

The process is that the gas enters into dust collector from the horizontal direction, under the gravity force, dust particles settling down gradually, and gas moving forward along the horizontal direction by centrifugal fan, the smaller dust particles settling down, so as to achieve dust collecting aim.

Xianrun Blower Centrifugal Fan for Inertial Dust Separator

Inertial dust separator is also called idle type dust chamber. Because the dust and gas in the air movement have different inertia force,the dusty gas collides baffle and dramatically changes the airflow direction, separating and collecting dust by inertia force according to motion trail.

Custom heavy Duty Industry Fan from China Supplier

Inertial dust separator has two kinds, collision type and rotary type. The former is install one baffle or multichannel baffle along the flow direction, dusty air collides the baffle, then dust particles separate from the gas.

Obviously, the higher speed of the dusty gas before collision the baffle, the lower speed after collision, the less dust, higher dust removal efficiency is higher.
The latter is that the dusty gas changes flow direction for many times, then separate dust in steering process.The smaller curvature radius of gas, the more steering speed, the higher dust removal efficiency.

Large Airflow Backward Curved Fans

This inertial dust separator has simple structure, low resistance, and is suitable for dry big dust particles.

Single Dust Collector Centrifugal Fan by Xianrun Blower

Single Dust Collector Working Principle:

Dusty gas enters into the chambers; filtrated by flat bag, intercepted on bag filter surface, purified gas through the bag; exhausted out by the centrifugal fan directly.

3000 cfm Industrial Backward Fans for Factory

With the filtering time increasing, dust accumulated on the bag filter surface is more and more, bag resistance also increases accordingly, which affect the dust collection efficiency.
At this time, starting shaking devices to shake off the dust, the the dust falls over the drawers and is pulled by manpower.

Single Bag Filter Dust Collector Application and Features:

The single dust collector is designed for cement plant silo top, and bottom, belt conveyor, part dust source removal, and other industries.

The single dust collector has the features of small volume, large airflow, compact structure, convenient and reliable operation, etc.
