Product Description

Boiler Dust Collector

The boiler precipitator refers to the equipment that separates the dust from the flue gas. Boiler deduster is commonly used in boiler and industrial production. Its function is to remove the particulate smoke from the boiler fuel and combustion exhaust gas, thus greatly reducing the amount of smoke and dust discharged into the atmosphere, which is an important environmental protection equipment to improve the environmental pollution and improve the air quality.

Bag type dust collector in power plant

brief introduction

The flue gas is entered into Venturi through the flue, and the inlet of the throat is sprayed evenly by the water. Because of the high speed movement of the flue gas, the water is melted into a fine ash in the fine water mist and wet flue gas. In this way, the ash and the water droplets are collided and condensed, especially the dust with small diameter can be dissolved in water mist. The first dust removal and desulphurization are achieved, which are fully prepared for the separation of the ash. After that, the flue gas will continue to impact the lime water in the tank. The dust in the flue gas and the SO2 in the flue gas react with the lime water in the pool to produce sulphate, and sink into the water under the action of inertia force, gravity, adhesion and cohesiveness. The second desulphurization process is completed at the bottom. The water fume aroused by the flue gas, the water mist and the flue gas after the washing are carried out at the same time, the gas and water are lifted simultaneously, the flue gas is fully reacted with the lime water, then the gas water is separated through the impeller dehydrator, and the water flows through the water pipe into the pool, and the flue gas is finished after third dust removal and desulphurization. After purification, the flue gas is purified. The gas is discharged into the atmosphere through the fan.

Bag type dust remover for industrial coal-fired boiler

The boiler deduster can be divided into steam precipitator, bag filter, boiler desulphurizing dust collector, vertical kiln bag filter and so on.
Vertical kiln bag filter
Working principle
(1) pre separation: the dust gas discharged by the shaft kiln enters the inlet pipe of the dust collector center through the flue. Under the negative pressure of the dust removal system, the dust gas enters the bag chamber of the dust collector evenly over the center of the ash bucket. The coarse particle dust in the dust smoke is directly falling into the ash due to the blocking of the diversion plate and the effect of its own gravity. Fight to complete the pre separation of dust.
(2) filter: the dust gas enters the filter bag through the flower plate hole, the dust is intercepted on the inner surface of the filter bag, the dust gas is purify through filter bag filtration, the gas after the purification enters the bag chamber, and then through the lifting switch valve exhaust channel and the outgassing pipe, the air exhausting machine is discharged into the atmosphere. The dust collector is provided with a top air outlet and a negative pressure operated internal filter dust remover. The cleaning methods can be divided into two ways: setting time and setting resistance. Timing cleaning is according to the time program, each room according to the adjustable time parameters automatic rotation cleaning, dust collector period of 0 to 2.5 hours in six gear can be adjusted, each room ash cleaning time is 10 seconds to 3 seconds six minutes. The timing cleaning control is the inlet and outlet pressure difference sampling of the dust collector and the conversion of the differential pressure transmitter into the telecommunication number. The working process is as follows: the inlet, the outlet, the air inlet and pressure device, the differential pressure transmitter, the solenoid valve cylinder lifting switch valve, and the manual control relay, besides the above two control methods, the manual is also set to be manual. The control mechanism can carry out normal ash removal control manually. For operation and management convenience, timing cleaning method is recommended. Four. The temperature controlled furnace flue gas temperature fluctuates in the range of 60-300 degrees, and the moisture content of the flue gas fluctuates within the range of 4-12%, in order to prevent the dedusting bag from the deduster and the malignant accident such as burning bag because of the high temperature.
The following measures are taken in the dust collector system:
(1) insulation measures must be taken in the intake pipe, body and ash hopper of the dust collector to prevent condensation of the dust collector.
(two) there is a temperature detection and automatic alarm device installed in the intake port and exhaust port of the dust collector, and a cold air inlet device is installed at the intake port. Once the flue gas exceeds the temperature range of bag dust removal, an alarm is generated and automatic temperature control measures are taken to ensure the safe operation of the dust collector.
(three) an electric heating and rapping device is installed on the ash hopper to avoid the problem of dust accumulation due to low temperature.

The boiler dust collector is suitable for dust removal, smoke elimination and desulphurization. It has the characteristics of low resistance, flexible installation and layout, high desulfurization efficiency and long service life.
