( 1 ) Cyclone dust collector

A cyclone dust collector is a dust removal device that uses the centrifugal force generated by rotating airflow to separate dust particles from dusty gas streams. It boasts advantages such as simple structure, compact size, no need for special auxiliary equipment, relatively low cost, moderate resistance, absence of moving parts inside the unit, and ease of operation and maintenance. Cyclone dust collectors are used for capturing... Particles larger than 5–15 micrometers can achieve a dust removal efficiency of up to 99%. .99 More than %.

Overview of the airflow and dust particle movement inside a cyclone dust collector:

The vast majority of the rotating airflow moves along the vessel wall, spiraling downward from the cylindrical section toward the bottom of the conical section, thus forming a descending, outwardly rotating dust-laden airflow. During this intense rotation, the centrifugal force generated expels dust particles—whose density is significantly greater than that of the gas—toward the vessel wall. Once these dust particles come into contact with the vessel wall, they lose their inertial force and, relying on the momentum imparted by the inlet velocity and their own gravitational pull, begin to fall along the wall surface into the dust collection hopper. After reaching the bottom of the conical section, the rotating downward airflow turns upward along the central axis of the dust collector, forming an ascending, inwardly rotating airflow that is then discharged through the dust collector’s exhaust pipe.

Another small portion of the airflow entering through the inlet flows toward the top cover of the cyclone dust collector, then moves downward along the outer side of the exhaust pipe. When it reaches the lower end of the exhaust pipe, it reverses direction and rises upward, exiting together with the ascending central airflow through the exhaust pipe. The dust particles dispersed within the airflow are carried away along with it.

2.1 Cyclone dust removal

2.2 Working principle

Dust-laden gas enters the middle shell through the inlet, is filtered by the filter cartridges, and clean gas then flows into the upper shell before being discharged through the clean-air outlet. Meanwhile, the dust is trapped on the outer surface of the filter cartridges. Subsequently, a blowing mechanism cleans the filter cartridges, shaking off the dust adhering to their outer surfaces into the dust hopper, from where it is removed by the ash-discharge conveyor.

When cleaning the filter cartridge, the controller program sends a signal to open the pulse valve through the solenoid valve. The compressed air in the air bag is ejected from the outlet of the pulse valve, and the high-pressure gas source is sprayed into the filter cartridge through the blowing port. Due to the effect of high-pressure gas, the filter cartridge undergoes rapid expansion, causing impact vibration. The vibration inertia and gas source are used to purge the filter cartridge, maintaining its good air permeability.

2.3 Main features

( 1) The filter cartridge uses imported polyester fiber as the filter element. A layer of ultra-thin sub-micron fibers is adhered onto a conventional filter core, and the fibers in this adhered layer are arranged extremely closely together. The tiny pores formed by this close arrangement can effectively trap most sub-micron-sized dust particles on the surface of the filter material.

( 2) The pleated design of the filter element increases the filtration area and makes the dust collector’s structure more compact.

( 3) The filter cartridge has a small height, resulting in low installation and maintenance workload.

( 4) Compared with dust collectors of the same volume, it has a relatively larger filtration area, a lower filtration air velocity, and low resistance.

( 5) The dust collector employs an online pulse-jet cleaning method for dust removal. The cleaning process is automatically controlled by a pulse controller, and users can also opt for time-based control as needed. The dust collector is equipped with multiple filter cartridges to increase its effective filtration area. When one or more filter cartridges meet the preset cleaning criteria, the pulse-jet system is activated to perform cleaning, while the other filter cartridges continue to operate normally. This approach ensures effective dust removal without disrupting the operation of the equipment, allowing the dust collector to run continuously.

( 6) High dust removal efficiency (generally exceeding 99.99%) and easy operation;

The dust collector includes: Available in three specifications: 04/24, 04/32, and 04/48. The dust removal efficiency for particles as small as 0.5 µm can reach 99.99%, meeting the Class II standards of the GB16297-96 Comprehensive Emission Standards for Air Pollutants.

The main structure of the dust collector is made of galvanized sheet or electrolytic plate and features a plastic-coated surface finish, offering excellent corrosion resistance.

The fan is a branded product from Southern Fan Company; the airflow and pressure head are selected according to actual requirements. An exhaust silencer can be optionally installed at the fan’s exhaust outlet. The exhaust duct is independently mounted on its corresponding foundation.

Dust removal motor power Above 22 kW, centrifugal fan speed: ≥2800 r/min; based on the dimensions of the soundproof room—5.0 m long × 5.0 m wide × 4.0 m high—the dust removal efficiency is ≥99%. .99%。

The spray exhaust gases discharged from the spray booth are treated by a two-stage dust removal system consisting of a cyclone dust remover and a differential-pressure-controlled pulse-jet bag filter. After treatment, the emission of particulate matter as an air pollutant is < 150 mg/m³—this concentration is below the maximum allowable emission limit of 150 mg/m³ for particulate matter (other) specified in the GB16297-96 Comprehensive Emission Standard for Air Pollutants, and thus complies with the national GB16297-96 Comprehensive Emission Standard for Air Pollutants.
