Problems solved by technology
[0003] Existing technology-Aiming at the practical problems of large air volume VOCs waste gas treatment, the technical solution of the electrothermal purification filter element is proposed for the enclosure structure, the air inlet surface, and the air outlet surface with one or more layers of porous sieve plates or adsorption beds filled with sieves. However, there is no solution for how to replace the electrothermal purification filter element in normal production after the adsorption of VOCs exhaust gas is saturated; prior art 2 proposes the use of molecular sieve runners and honeycomb activated carbon runners for VOCs exhaust gas adsorption and desorption for the practical problems of VOCs exhaust gas treatment , Concentration, and combustion technical solutions, it is undoubtedly feasible to use a mechanical runner to solve the technical solution of replacing the adsorbent after the VOCs exhaust gas is saturated, but the sealing problem must be solved for moving equipment such as the runner, especially the rotary The problem of VOCs exhaust gas leakage due to seal failure under continuous production conditions during wheel replacement

Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0020] Such as figure 1 , figure 2 , image 3 As shown, a chain-driven grate bed operation method for cooling and activating VOCs waste gas adsorbent is characterized in that: step 1, the adsorbent particles moving and falling from the VOCs waste gas adsorbent desorption pyrolysis furnace fill the material leg 1, from Inject airflow into the vertical channel of the desorption pyrolysis furnace, check whether there is airflow escaping, open the material leg 1 and adjust the speed of the sprocket 7 of the chain drive grate bed body 2, so that the adsorbent particles can be spread evenly on the chain drive grate bed On the row 8, the thickness is not more than 10mm. The chain drive grate bed row 8 includes the sprocket 7, the chain 5, the grate bed row 11, and the air distribution plate 6. The grate bed row 11 includes the horizontal pin 10, th...

The invention relates to the technical field of the environment protection, and specifically relates to a chain drive grate running method for VOCx waste as adsorbent cooling activation. The method ischaracterized in that desorbed adsorbent continuously moves under the effect of gravity, and then is uniformly spread to the chain drive grate bar through diplegs, the adsorbent temperature is higherthan 250 DEG C at this time, an air distributor imports the tail gas discharged after being treated by VOCs waste gas environment-friendly purification facility, the tail gas flows into through the gap between the adjacent grate bar plates so as to blow and cool the adsorbent spread on the chain drive grate bar, thereby quickly accomplishing mass and heat transfer process with the adsorbent particles, and then discharging through a smoke outlet of a kiln tank.
Description
technical field [0001] The invention relates to the technical field of environmental protection, in particular to a method for operating a chain-driven grate bed for cooling and activating a VOCs waste gas adsorbent. Background technique [0002] Gaseous pollutants emitted by industry are the main source of atmospheric environmental pollutants, among which volatile organic compound waste gas (VOCs) is a gaseous pollutant that is seriously harmful to the environment, and it is also an occupational hazard that affects the health of operators in the workplace It is widely derived from chemical industries such as paints, coatings, coatings, lubricants, and rubber. Due to its huge destructive effect on the human body and the natural environment, the country has issued relevant laws and regulations to strictly control its governance and emissions. At present, the commonly used treatment methods of organic waste gas treatment technology include combustion method, chemical oxidatio...
