A self-generating steam protection and fire extinguishing technology

Abstract

The invention discloses a self-generated steam protection and fire extinguishing technology, which includes: through the remote monitoring system, after the fire in the reaction chamber is found, through the remote operation of the upper computer system and the PLC control system, the action of the explosion-proof electromagnetic valve is controlled, and the water source passes through the reaction chamber. The atomizing nozzle is sprayed onto the partition in the reaction chamber in the form of water mist. Because the reaction chamber contains high-temperature oil and gas, the water mist will evaporate instantly into steam, and the steam will reduce the temperature of the combustible gas in the entire reaction chamber. At the same time, the dilution can The concentration of gas and oxygen can be controlled by detecting the oxygen content and temperature in the reaction chamber to control the amount of spraying water. At the same time, the host computer system and the PLC system can control the amount of spraying water according to the oxygen content and issue an alarm message. The entire control system is powered Provides uninterruptible power supply for continuous use in emergency situations on site. The structure of the present invention has the advantages of simple structure, quick cooling and fire extinguishing, and can effectively extinguish fires caused by ignition of industrial and hazardous wastes by high-temperature flue gas during indirect heating.

Description

technical field [0001] The invention relates to the application of fire extinguishing in a heating chamber of a solid waste heat treatment device, in particular to a steam protection and fire extinguishing technology. Background technique [0002] In the field of oily waste treatment, more and more hazardous waste disposal enterprises have begun to adopt heat treatment technology due to its advantages of thorough treatment, no chemical addition, and no secondary pollution. [0003] In the process of using heat treatment technology (thermal desorption, drying, pyrolysis, carbonization, incinerator) to treat oily waste, a large amount of combustible gas will be generated during the heating process, and the temperature of the furnace body will reach above 200°C. Elements Among them, combustibles and ignition sources are two elements. Once the air (combustion aid) enters the furnace, fire or deflagration will occur in the furnace, posing a threat to safe production. [0004] In...

Problems solved by technology

[0004] In response to this situation, the existing safety protection measures mainly include fire-fighting water to extinguish the fire. When the fire-fighting water enters the furnace, it is easy to cause the furnace body in a high-temperature state to rapidly cool down and quench, and the material of the furnace body becomes brittle, which affects the service life of the furnace body. The cost of nitrogen fire extinguishing is relatively high and the equipment is complicated
