Embodiment Construction

[0024] Please refer to figure 1 , figure 2 , the implementation of the device GRTO of the present invention will be described in detail.

[0025] Before (9) is ignited, fresh air should be used to purge the whole system to clean up the organic waste gas or diesel oil remaining in (10) and the furnace to prevent explosion during ignition. The time of purging is hardware design, and the hardware is linked with the flame control system. If the purging is not completed, the ignition cannot be carried out to ensure the safety of the system. Fresh air enters one of (2) from (3), and the other two are closed, entering (10) and purging the furnace. Then discharge (4) and (5) into the atmosphere, switch every 3 minutes, and purge for about 15 minutes.

[0026] After the purging is completed, (9) ignite and heat up, keeping it at 3 degrees per minute, and the heating time is about 3 to 4 hours, so that the temperature of (10) rises slowly. Brick cracking may shorten the life of th...

Abstract

The invention discloses a device guarantee regenerative thermal oxidizer (GRTO) capable of treating inflammable and explosive industrial organic waste gas more safely. The GRTO comprises an inlet gas flue, inlet gas switching valves, a furnace body, outlet switching valves, a purging air duct, an outlet flue and a burning system. Heat storage beds are filled with regular honeycomb ceramic heat accumulators, and the regular honeycomb ceramic heat accumulators are mainly made of dense cordierite and have the advantages of excellent acid, base and organic medium corrosion resistance, good heat storage effect, high heat recovery efficiency, small wind resistance, small coefficient of expansion caused by heat and contraction caused by cold, good anti-cracking ability, long service life and the like. All parts making contact with waste gas are coated with a high-temperature-resistant and corrosion-resistant coating, so that corrosion of the parts making contact with steel plates of the furnace body is avoided, and the relatively long service life of the furnace body can be guaranteed. The device GRTO can effectively decompose the organic waste gas into carbon dioxide and water vapor, the heat recovery rate is up to 95%, and the GRTO is safe, reliable, high in purification efficiency and suitable for organic waste gas treatment in multiple fields.

Description

technical field [0001] The device GRTO of the invention relates to the field of environmental protection, in particular to a device for treating organic waste gas. Background technique [0002] At present, in the industry, organic waste gas treatment devices include TO (Thermal Oxidizer, direct combustion furnace), RTO (Regenerative Thermal Oxidizer, regenerative oxidation furnace), RCO (Regenerative catalytic oxidation, regenerative catalytic oxidation furnace) and so on. The energy consumption of TO equipment is relatively large. In the current energy shortage, with the enhancement of people's awareness of environmental protection, the application of TO furnace in the industry is relatively small. At present, RTO is widely used in the industry, and its removal efficiency can reach 95% to 98%, and the residence time is 0.3 to 1 second, but its safety and stability are not strong. During the use of RCO, viscous compounds will stick to the surface of the regenerator and cata...
