Embodiment 1
[0032] The process equipment used is as attached figure 1 Shown, where the buffer adjustment device is figure 2 The shown fixed bed one-way buffer adjustment device, the purification treatment device is RTO, the adsorption material is activated carbon, the dynamic adsorption capacity of its reversible adsorption and desorption is 100mg / g, the buffer adjustment device operates at normal temperature and pressure, and the VOCs concentration in the VOCs exhaust gas is 500-10000mg / m 3 Fluctuating within the range, the concentration of the VOCs exhaust gas after the buffer adjustment treatment device is 3000-7000mg / m 3 , The stable operation of the RTO for 48 hours has no abnormal situation, and the exhaust gas of the RTO meets the environmental protection requirements.
[0033] In addition to discarding the buffer adjustment device, other operations are the same as the above operating conditions. After RTO runs for 10 hours, an abnormality occurs, and the exhaust gas of RTO does...
Embodiment 2
[0035] The process equipment used is as attached figure 1 Shown, where the buffer adjustment device is image 3 The shown single-tank fixed-bed two-way buffer adjustment device, the purification treatment device is RTO, the adsorption material is macroporous resin, the dynamic adsorption capacity of its reversible adsorption and desorption is 135mg / g, the buffer adjustment device operates at normal temperature and pressure, VOCs waste gas Medium VOCs concentration is 500-10000mg / m 3 Fluctuates within the range, VOCs exhaust gas is introduced from the intake pipe, passes through the two-way valve, first enters the tank from the A end, and moves to the B end; when the adsorption reaches a certain level, switch the steering valve so that the organic waste gas enters the tank from the B end , the right end of the gas enters the B end, which is purified by the adsorption material into a clean gas, and blows to the A end where the VOCs have been adsorbed, desorbing and releasing th...
Embodiment 3
[0039] The process equipment used is as attached figure 1 Shown, where the buffer adjustment device is Figure 4The 8-sector valve rotary buffer adjustment device is shown, the purification treatment device is RTO, the adsorption material is ultra-high cross-linked resin, the dynamic adsorption capacity of its reversible adsorption and desorption is 150mg / g, and the buffer adjustment device operates at normal temperature and pressure. VOCs concentration in VOCs exhaust gas is 500-10000mg / m 3 Fluctuating within the range, VOCs waste gas first enters from chambers 6, 7, and 8, and after adsorption and purification, the gas passes through the closed cavity at the other end of the tank and then enters chambers 2, 3, and 4 to be discharged. At this time, chambers 1 and 5 are sealed; After a certain period of time, the gas is switched to chambers 7, 8, and 1 to enter, chambers 3, 4, and 5 to exit, and chambers 2 and 6 are sealed. The 8 adsorption chambers work in a cycle like this...
