Wedge-wire screen cylinders are fully welded, cylindrical filtration elements. They are constructed by continuously wrapping a V-shaped (trapezoidal) profile wire around a series of axial support rods and securing it via resistance welding. This process creates a uniform, continuous slot that is wider on the outside and narrower on the inside. These screens are primarily used within tanks, pressure vessels, and filter towers for applications such as water collection and distribution, resin retention, sand control, fluid flow distribution, and solid-liquid separation. They are widely integrated into equipment such as resin tanks, adsorption towers, water treatment filters, and distillation column internals, serving as a core cylindrical filtration component in chemical processing, water treatment, and environmental protection systems.

Wedge-wire screen panels are constructed by arranging V-shaped profile wires transversely and welding them onto longitudinal support rods, forming a flat (or alternatively, curved or bent) screening and filtration component. These panels are primarily used for applications such as planar water or gas distribution, material dewatering, solid-liquid separation, packing support, base plates for filtration equipment, and curved screens. They are typically employed for flat-surface filtration and screening within tanks or vessels, distinguishing them from cylindrical wedge-wire screen tubes.

A distillation column is a core mass-transfer device used in chemical separation.

Waste gas enters from the bottom of the tower and flows upward, while an absorbent is sprayed from the top and flows downward, creating a counter-current gas-liquid contact. Pollutants in the waste gas are transferred into the liquid phase, where they undergo dissolution or neutralization reactions. The purified gas passes through a demister at the top of the tower before being discharged. The absorbent liquid is circulated from the bottom of the tower, with fresh reagents added or spent liquid removed as needed, depending on operational conditions.

The resin vessel—constructed as a pressure vessel (or non-pressure vessel) from carbon steel, duplex stainless steel, or stainless steel—is filled with macroporous ion-exchange resin for the adsorption of gaseous media. In exhaust gas treatment applications, it is used for the adsorption and recovery of organic waste gases. The vessel is equipped with internal water/gas distribution components, as well as upper and lower Johnson-type screen pipes or screen plates, to ensure uniform distribution of the media.

VOCs exhaust treatment covers are specialized sealing components designed for industrial exhaust collection and treatment systems. They are primarily used to enclose open emission sources—such as points along production lines, reaction tanks, cleaning vats, material mixing stations, and the inlets/outlets of spray towers—to facilitate the containment and collection of pollutants. Through their fully sealed design, these covers effectively prevent the fugitive release and dispersion of VOCs, odors, smoke, and dust. By consolidating scattered exhaust streams, they channel the emissions toward downstream treatment equipment. As an essential foundational component of any comprehensive VOCs treatment system, these covers are widely utilized in both the retrofitting of existing facilities and the construction of new projects across various industries.

A biological deodorization unit is a system for purifying waste gas through biological processes. It utilizes microbial metabolism to break down substances such as hydrogen sulfide, ammonia, and other volatile odorous compounds. The unit contains biological packing material, the surface of which hosts a population of acclimated, odor-degrading microorganisms. As the waste gas passes through the system, it is first humidified via a spray process before entering the biological filter bed, where the pollutants are degraded by the microorganisms into harmless substances such as carbon dioxide and water.
