Environmental Protection Equipment
Bag filter dust collector, with a compact size, is suitable for various independent dust-generating points, collecting and processing dust on-site. The basic structure includes a dust collection chamber, centrifugal fan, filter bags, dust collector, and microcomputer controller, among others. The entire dust removal process is the result of a combination of effects including gravity, inertial force, collision, electrostatic adsorption, and sieving. It can be put into use simply by providing electric power, making it convenient to install and operate. It is widely used in industries such as building materials, grain, tobacco, chemical, metallurgy, machinery, casting, coal, electric power, and medicine.
Cartridge Dust Collector is a dust collector that uses filter cartridges as the filtering elements or employs pulse-jet cleaning. Cartridge dust collectors can be classified by their installation method into inclined insertion type, side-mounted type, hanging type, and top-mounted type. Based on the material of the filter cartridges, they can be divided into long-fiber polyester cartridge dust collectors, composite fiber cartridge dust collectors, anti-static cartridge dust collectors, flame-retardant cartridge dust collectors, coated cartridge dust collectors, and nano cartridge dust collectors, among others.
Cyclone dust collector is a device that induces rotational movement in a dust-laden airflow, using centrifugal force acting on the dust particles to separate them from the gas. The cyclone dust collector consists of an inlet duct, outlet duct, cylindrical body, conical body, and ash hopper. With its simple structure, the cyclone dust collector is easy to manufacture, install, and maintain, and both equipment investment and operational costs are relatively low. It has been widely used to separate solid and liquid particles from gas streams or to separate solid particles from liquids.

Pulse Jet Dust Collector is a high-efficiency baghouse dust collection equipment. It is a large-scale dust removal device characterized by large air volume handling, effective dust cleaning, high dust collection efficiency, reliable operation, convenient maintenance, and small footprint. Dust-laden gas enters through the air inlet and, as it passes through the hopper, some large particles of dust are separated out due to inertial forces and fall directly into the hopper. After passing through the hopper, the dust-laden gas enters the filter bag area of the cabinet, where the gas passes through the filter bags and the dust is trapped on the outer surface of the filter bags. The cleaned gas then enters the upper cabinet through the mouth of the filter bag and is discharged from the air outlet.
The filter bag is a critical component that determines the dust collection efficiency and working temperature of a baghouse dust collector. The cost of replacing filter bags constitutes a significant portion of the main maintenance expenses for a baghouse dust collector. Therefore, the service life of the filter bag is related to the operating status and usage costs of the dust collector. When selecting filter bags, one should consider factors such as the temperature, humidity, and chemical properties of the gas; the size, weight, and shape of the particulate matter; as well as the dust concentration, filtration velocity, dust cleaning method, emission concentration, and the working principle of the baghouse dust collector.
The filter bag cage serves as the "ribs" of the filter bag and is formed by welding in one go using automatic welding equipment. Its features include: secure welding, a smooth and straight appearance that prevents damage to the filter bag, lightweight application, ease of installation and maintenance, and surface treatment using galvanization, silicone coating, or plastic spraying processes.
Valve
In the realm of fluid control systems, valves play a crucial role in regulating flow, ensuring safety, and optimizing performance. Check valves, gate valves, and ball valves each serve specific purposes in fluid control systems. Check valves prevent backflow, gate valves provide full-port shut-off, and ball valves offer versatile flow control. The choice of valve depends on the specific application, considering factors such as flow requirements, pressure ratings, and operational needs.
