Gas Supplement RegulatorProduct Overview:

The gas supplement regulator is a critical device specifically designed for dense-phase pneumatic conveying of powders. Its core feature lies in precisely controlling the powder flow rate over a wide range by adjusting the bypass gas supplement volume. This device adopts an inner and outer sleeve structure, with the central pipe conveying pulverized coal and the outer annular pipe delivering secondary air, forming a jet at a certain angle to achieve circumferential mixing with the central powder material. This product is available in both adjustable and non-adjustable structures to meet the needs of different working conditions.

The adjustable gas supplement device consists of two sleeves: the inner pipe conveys pulverized coal, while the annular gap between the outer and inner pipes supplements gas. This design alters the conveying environment of the pulverized coal, significantly improving the pneumatic conveying conditions in the coal transport pipeline. The non-adjustable gas supplement device, on the other hand, features a simple structure, easy replacement, and low cost.

Among them, the swirl-type gas supplement regulator is an innovative design in this series. By improving the straight conical annular gap air passage and adopting a swirl air passage, it ensures more thorough and uniform mixing of powder and gas. This design allows for arbitrary adjustment of the powder-to-gas mixing ratio, thereby generating a pulsation phenomenon. This not only greatly enhances conveying capacity but also reduces conveying costs, decreases failure rates, and extends service life.

In terms of application, this gas supplement regulator is widely suitable for pneumatic conveying and dust removal systems involving pulverized coal injection in blast furnaces, fly ash in power plants, cement, dust, and other powders. It is precisely installed at the outlet of the injection tank on the pulverized coal main pipe, used to dilute the high-concentration pulverized coal coming out of the injection tank. This achieves an optimal state of solid-gas mixture, forming a stable dense-phase solid-gas two-phase flow, thereby enabling long-distance dense-phase conveying of pulverized coal.

The design temperature of this device is 100°C, and the design pressure is divided into three grades: 1.0MPa, 1.6MPa, and 2.0MPa. Its internal design is unique; by adjusting the round nut, the gap of the gas supplement air passage can be easily changed, thereby precisely regulating the gas supplement volume and flow rate. This ultimately achieves accurate control of the coal injection volume, meeting the optimal demands of production. Furthermore, this gas supplement regulator represents a significant technological breakthrough. It not only solves the problems of flow regulation and powder-gas mixing but also, through its swirl design, ensures more thorough mixing of powder and gas, generating a pulsation phenomenon that greatly enhances conveying capacity and efficiency. Additionally, the device boasts advantages such as a simple structure, easy operation, and low cost, making it an indispensable key equipment for long-distance dense-phase conveying of pulverized coal.
In summary, with its unique design and high performance, the gas supplement regulator provides a reliable solution for dense-phase pneumatic conveying of powders and is an indispensable part of industrial production.
