Introduction to Safety of Shengze Environmental Protection Catalytic Combustion Equipment

due toactivated charcoalThe exhaust gas in adsorption, desorption, and catalytic combustion systems is flammable and explosive gas, and high-temperature gas is generated during the desorption and regeneration of catalytic combustion devices. So the safety and reliability of the system are very important. This article focuses on Shengze Environmental ProtectionCatalytic combustion equipmentThe security system ensures the safe operation of the system in unmanned situations.

Set the temperature control of the supplementary air cooler: When the temperature inside the activated carbon adsorption bed is higher than the set value, the supplementary air cooler will automatically start to supplement the cold air, reduce the temperature inside the adsorption bed, and ensure safe operation.

The activated carbon adsorption box and catalytic combustion device are respectively equipped with over temperature automatic sound and light alarm, power-off, and air supply cooling devices.

Activated carbon adsorption boxInternal fire protection nitrogen fire prevention device: When the temperature inside the activated carbon adsorption bed exceeds the set value, the nitrogen valve will automatically open to ensure safety.

High temperature equipment and pipelines shall be insulated with thermal insulation measures.

Strictly implement the relevant specifications and regulations regarding lightning protection, grounding safety measures, and protective measures to prevent various accidents.

Activated carbon adsorption bed and catalytic combustion device are respectively equipped with pressure relief devices.

Perform catalytic combustion again to ensure safe operation. A fire damper is installed in the connecting pipeline between the activated carbon adsorption bed and the catalytic combustion device: when the flame enters the flame arrester, it is cut into many small flame streams by regular flame arrester elements. Due to the heat transfer and wall effect, the incoming gas is cooled, so that the cooled gas cannot reach the ignition temperature. Without the ignition temperature, combustion cannot be formed, and ultimately the flame stream is quenched, thus achieving the purpose of flame arrester.

Set dilution valve to control concentration: The high concentration gas desorbed from activated carbon is supplemented with natural air to reduce exhaust gas concentration before entering catalytic combustion.
