Circulating purification device and method for fire smoke

Abstract

The invention discloses a circulating and purifying device and method for fire smoke. The device comprises a smoke collecting module, a secondary smoke combustion module, a water spraying, dust removing and cooling module and a harmful gas removing module which are connected in sequence, wherein the secondary smoke combustion module comprises a smoke co-combustion chamber, a combustion generator, an air preheating bin and an oxidizing gas pipe valve, an ignition part of the combustion generator is arranged on the inner side of the smoke co-combustion chamber, a fuel part and an ignition control part of the combustion generator are arranged on the outer side of the smoke co-combustion chamber, an air preheater is arranged in the air preheating bin, and the oxidizing gas pipe valve is arranged between and connected with the smoke co-combustion chamber and the air preheating bin. According to the invention, the fire smoke is effectively treated, environmental pollution is avoided, the recycling of wastes is also realized, the high-temperature harmful fire smoke is possibly purified into green gas which can be breathed by people, and the technical bottlenecks of difficulty in ventilation and smoke discharge and high construction and maintenance cost in places such as subsea tunnels and large underground spaces can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of decontamination, purification and recycling of fire smoke, and in particular relates to a fire smoke circulation purification device and method. Background technique [0002] In recent years, with the advancement of technology, the equipment and environment of various workplaces have become increasingly complex, and the fire risk is self-evident. Especially for large enclosed spaces, on the one hand, due to factors such as the complexity of the environment, it is difficult for rescuers and large-scale rescue equipment to provide immediate support, making it difficult for trapped people to escape in a short time; on the other hand, it is difficult to quickly eliminate fire smoke with existing technical means gas, seriously threatening the lives of the trapped people. Therefore, how to quickly eliminate fire smoke becomes the key to ensuring the safety and health of trapped people when a fire occurs. [0...
