Lihuang RTO equipment due to inadequate safety design, improper operation and other reasons, explosion accidents, designers in the design of RTO equipment, should fully consider the safety of equipment, then how to ensure the safety of equipment, what should be considered?

The VOCs composition of enterprises is complex and diverse, and the gas volume is unstable, especially the intermittent production characteristics of fine chemical enterprises, so that the concentration of organic waste gas and the amount of waste gas will have intermittent changes. In the collection of technical data, it is necessary to fully understand the production process and main sources of waste gas of the enterprise and rationally select equipment and facilities according to the actual situation of the enterprise.

When enterprises build new VOCs waste gas treatment equipment, RTO device has been considered in the overall layout, and the equipment runs stably without safety production accidents. The newly added RTO device can be regarded as a joint device with the chemical process device in the factory. The fire spacing of the equipment and buildings should be determined according to the fire spacing of adjacent equipment and buildings, and the fire spacing should conform to the national standard. If the fire spacing really can not meet the national standards, you can consider setting up a firewall, or the original building doors and Windows sealing, the formation of non-burning solid wall, the fire spacing can be less than the national standards, but not less than 15m.

For organic waste gas containing acidic gas, it is necessary to remove acidic gas in the waste gas through the secondary scrubber tower to reduce the corrosion of acidic gas on RTO furnace body, valves and other equipment. At the same time, the scrubber tower also plays a role of buffer tank to avoid uneven mixing of organic gas in local areas and high concentration of organic matter. For organic waste gas without acid gas, according to the original concentration of waste gas, a buffer box should be set before the waste gas enters the furnace, and an emergency dilution valve should be set on the buffer box.


Lihuang RTO furnace by setting buffer tank, adjust the air volume and other pretreatment facilities, you can strictly control the RTO furnace entrance organic concentration and flow rate, to ensure relatively stable, safe operation. Dust should be removed from the dust-containing waste gas, otherwise the waste gas will enter the RTO furnace and cause the heat storage body in the furnace to be blocked, affecting the heat exchange efficiency.

For the collection of breathing organic waste gas of tanks in the tank area, it should be collected according to the classification of fire prevention, and water sealing tanks should be set up to ensure the safety of the whole tank system. Because the lower limit of the explosion of organic matter will be greatly reduced with the increase of the gas temperature, and the sudden discharge of organic waste gas in chemical enterprises, the exhaust gas pipeline should be added at the bend of the pipeline explosion plate, and the pipeline flame arrester is set at the device boundary area. Waste gas pipeline material selection should consider corrosion, static electricity, cost and other factors, metal pipeline should consider anti-static design.

Heat storage body to high temperature resistance, RTO equipment operating temperature is generally 750℃-950℃, so generally choose temperature resistance of more than 1250 degrees Celsius material as heat storage body, generally choose honeycomb ceramics or modular ceramics and other structured materials, have enough mechanical strength and corrosion resistance, service life is not less than 40000h.

Lihuang environmental protection specializes in the application of VOCs waste gas incinerator and waste heat recovery system engineering, paying special attention to equipment maintenance and optimization of old customers and other aftermarket services. The company develops step by step, absorbing innovation, and has obtained a number of patents and qualifications.
