Introduction to Types and Working Principles of Boiler Dust Removal Devices

Introduction to Boiler Dust Collector

Boiler Dust RemovalNo Chinese content provided.A boiler deduster, as the name implies, is a specialized boiler dust removal device. Its true definition is a boiler dust removal equipment that purifies and removes waste gases such as smoke and dust particles from flue gas. Therefore, it is also known as a boiler flue gas deduster. It can effectively separate dust from flue gas, making the boiler deduster a commonly used auxiliary dust treatment equipment in modern boilers and industrial production.

Section II: Types of Boiler Dust Collectors

Baghouse dust collectors can be mainly categorized according to their cleaning methods.:Mechanical vibration, air jet reverse blowing, and pulse jet types. The general dust removal method has a significant impact on the performance of bag dust collectors, making it a major criterion for them. The types and working principles of boiler dust collectors (see attached figure) can be divided into gravity, inertial, and centrifugal based on the different primary dust removal mechanisms.(Mechanical force, filtration, washing, and electrostatics6Large types, categorized by the degree of gas purification, can be divided into four main types: ultra-purification, medium-purification, fine-purification, and super-purification. Additionally, based on the dust removal efficiency of the dust collector, they can be further classified into high, medium, low efficiency, and high, medium, low resistance types.

Section 3: Principle of Operation of the Boiler Dust Collector

The boiler dedusting equipment is connected from the inlet to the pre-cooling unit, which is then connected to the chimney of the boiler. The dust-laden flue gas passes through the cooling unit, and after cooling, it enters the inlet pipe of the boiler bag dedusting equipment. It then flows into the ash hopper and proceeds to each filter chamber, where it is filtered through the bags. The clean air rises inside the bags into the clean air chamber and is subsequently extracted from the dedusting unit by the suction force of the fan, and finally discharged to the desulfurization unit for desulfurization treatment.

Therefore, there are many types of boiler dust collectors, each with its own working principle and advantages and disadvantages (which will be introduced in subsequent chapters on this website). We can choose the dust collection equipment that suits the user's characteristics based on a comparison of these advantages and disadvantages.
