Dust removal equipment manufacturers, is the separation of dust from the flue gas is called dust collector or dust removal equipment. The performance of a dust collector is expressed in terms of the amount of gas that can be handled, the resistance loss when the gas passes through the dust collector, and the dust removal efficiency. At the same time, the price of the dust collector, the operation and maintenance cost, the length of its service life and the difficulty of its operation and management are also important factors in considering its performance. Dust collectors are commonly used facilities in boilers and industrial production.

A dust collector, a device that separates dust from flue gases is called a dust collector or dust removal equipment. The performance of a dust collector is expressed in terms of the amount of gas that can be handled, the resistance loss of the gas as it passes through the dust collector, and the dust removal efficiency. At the same time, the price of the dust collector, the operation and maintenance cost, the length of its service life and the difficulty of its operation and management are also important factors in considering its performance. Dust collectors are commonly used facilities in boilers and industrial production.

The dust suction hood is set up at each place where the ash is emitted, and the dusty gas is transported to the dust collector through the pipeline air circuit, in which the dust is collected in the dust collector after gas-solid separation, and the clean gas is introduced into the main pipe or discharged into the atmosphere directly, i.e., the dust collector system, of which the dust collector is an important group part. From the point of view of ventilation and dust removal, dust is able to longer be floating state in the air all the solid particles, is a kind of dispersion system, called aerosol, in which the air for the dispersion medium, solid particles for the dispersed phase. Dust collector is the solid particles from the aerosol separated from the equipment.

The technical performance index of dust collector mainly includes dust removal efficiency, pressure loss, processing gas volume and load adaptability and other aspects. 

1, dust removal efficiency

In the design of dust removal engineering generally use the full efficiency as an assessment index, sometimes also expressed in graded efficiency.

(1) Full efficiency The full efficiency is the percentage of the amount of dust removed by the dust collector and the amount of dust entering the dust collector. The following formula:

η = G2 ÷ G1 × 100%

Where η--------- efficiency of the dust collector, %;

G1--------- amount of dust entering the dust collector, g/s;

G2--------- amount of dust removed by the dust collector, g/s;

Because the dust amount can not be measured directly in the field. Should first measure the dust concentration in the dust collector import and export airflow and the corresponding air volume, and then calculated using the following formula:

Where Q1--------- dust collector inlet air volume, m3/s;

C1--------- inlet concentration of dust collector, mg/m3;

Q2--------- dust collector outlet air volume, m3/s;

C2--------- dust collector outlet concentration, mg/m3.

(2) Total efficiency

In the dust removal system if there are dust removal efficiency of η1, η2...... respectively .ηn when several dust collectors are operated in series. The total efficiency of the dust removal system is expressed by η, calculated according to the following formula

η=(1- η1)(1- η2)... (1- ηn)

(3) Penetration rate The penetration rate ρ is the percentage of the dust discharged at the outlet of the remover and the dust fed in at the inlet, and is calculated according to the following formula:

(4) Grading efficiency The grading efficiency n is the dust removal efficiency of the dust collector for dust within a certain particle size d or particle size range △ d, as shown in the following formula

2、Pressure loss

Pressure loss of dust collector is the difference between the absolute value of full pressure of the inlet and outlet of the dust collector, which indicates the mechanical energy consumed by the gas flowing through the dust collector, and it can be calculated by the following formula when we know the value of ξ of the local resistance coefficient of the dust collector. In the field can be measured directly by the pressure gauge.

Where △p--------- pressure loss of the dust collector, Pa;

ρu--------- density of treated gas, kg/m3;

υ --------- gas velocity at the inlet of dust collector, m/s.

3、Processing gas volume

Indicates the size of the dust collector processing gas capacity, generally expressed in volume flow rate (m3/h or m3/s), but also expressed in mass flow rate (kg/h or kg/s).

4、Load adaptability

Load adaptability of good dust collector, when the amount of gas treated or pollutant concentration fluctuations in a wide range, can still maintain a stable dust removal efficiency, moderate pressure loss and high enough operating efficiency.
