Coal fired boiler dust collector

The purification method of the dust collector for coal-fired boilers is external filtration, and the dust containing gas enters each unit filter chamber through a guide pipe and is installed through the flue gas guide installed in the ash hopper; Due to the sufficient and reasonable vertical spacing between the bag and the upper opening of the air inlet in the design, there is proper airflow guidance and natural flow dispersion, resulting in an even distribution of airflow throughout the entire filtering chamber. The particles and dust in the dusty gas are naturally settled and separated, and then directly fall into the ash hopper. Other dust is guided by the airflow guidance system and enters the middle box with the airflow. The filtered clean gas passes through the filter bag and is discharged through the upper box and exhaust pipe.

Coal fired boiler dust collector is a dust removal equipment specifically designed for treating boiler flue gas. It is designed to address the characteristics of coal-fired boiler flue gas, such as high temperature, high humidity, high sulfur content, and strong corrosiveness.

Coal fired boiler dust collectors are composed of the boiler dust collector body, maintenance system, compressed air system, control system, etc., which operate smoothly, have low resistance, low energy consumption, good dust cleaning effect, and occupy small air volume.

The dust remover of coal-fired boiler uses a wet desulfurization and dust removal technology developed based on the mechanism of multiphase turbulent mass transfer, which separates the centrifugal water film dust removal and spray boiling desulfurization and dust removal into one phase, accelerates the flue gas with dust and without specific clinical effect as the main body through Venturi and the cyclone made, and collides with the atomized liquid sprayed in front of Venturi and the desulfurization liquid sprayed at the upper end of the tower to form a rotary shear force. The gas and liquid are peeled at high speed, fully mixed, and then rise into the boiling reaction layer. The dust and without specific clinical effect as the main body in the flue gas are captured and absorbed by the fine liquid particles in the desulfurization liquid. Because the atomized liquid particles produce a large number of interfaces, The efficiency of capturing and absorbing smoke and dust per unit liquid volume and no specific clinical effect as the main body is good.

The concentrated performance of coal-fired boiler dust collectors is reflected in their energy-saving and environmental protection technology. To purchase this technology for time control, we can obtain it through the introduction of the product in the product specification book. Its working efficiency is good and the standard is higher, so it can meet the needs of the field.

Daily maintenance of coal-fired boiler dust collector:

1. Regularly check the usage status of vulnerable parts based on the list of vulnerable parts and replace them in a timely manner.

2. Regularly replenish lubricating oil to the parts of the equipment that require smoothness. Replace the # 2 sodium based grease in the gearbox of the cycloidal pinwheel reducer every six months, and replenish the # 2 lithium based grease on the smooth points of the bearings once a week.

3. Regularly check if there is any blockage in the differential pressure transmitter and stop clearing in a timely manner.

4. Based on the dust collection capacity of the dust removal system, the dust collection capacity of the dust removal equipment and the ash discharge cycle are determined.

5. The drainage cycle is determined based on the water accumulation in the air bag of the air-water separator in the compressed air system, with the aim of preventing moist air from entering the bag.

6. Regularly check whether the pulse cleaning system of the dust collector can spray normally. If it is not normal, focus on checking whether the pulse valve diaphragm and solenoid valve are malfunctioning or damaged, and timely maintenance or replacement should be carried out.

7. Regularly check whether the equipment can operate normally based on changes in resistance during operation.
