Description

RTO air inlet separation device for pretreatment of high-concentration waste gas Technical Field The invention relates to the technical field of waste gas separation, in particular to an RTO air inlet separation device for pretreatment of high-concentration waste gas. Background In the field of industrial waste gas treatment, regenerative Thermal Oxidizer (RTO) is widely used for high concentration organic waste gas treatment due to high heat recovery efficiency and pollutant decomposition capacity. However, RTO has strict requirements on intake quality, and solid particles and liquid impurities entrained in exhaust gas can seriously affect the operation stability and service life of the exhaust gas, so that the existing exhaust gas pretreatment technology still has a plurality of defects in adapting to the intake requirements of RTO. The existing waste gas pretreatment device is mainly used for removing impurities by adopting modes such as simple filtration, gravity sedimentation or conventional cyclone separation, and the separation precision and efficiency are difficult to meet the high-concentration waste gas treatment requirement. For solid particles with smaller particle sizes and vaporific liquid impurities, the conventional equipment cannot realize high-efficiency interception, and the impurities are attached to the surface of a channel of a heat accumulator after entering RTO along with waste gas, so that fouling and blocking of the channel are gradually formed. The heat accumulator channel blockage can greatly reduce heat exchange efficiency, so that RTO energy consumption is obviously increased, and meanwhile, uniform distribution of waste gas in a cavity is influenced, so that local temperature is too high or combustion is insufficient, and pollutant decomposition efficiency is reduced. The adaptability and the regulating capability of the existing pretreatment device are insufficient, and the dynamic fluctuation of the waste gas flow and the impurity content in the industrial production is difficult to match. When the flow of the waste gas is reduced, the air flow speed is insufficient, and effective separation power cannot be formed, so that the impurity sedimentation is incomplete. The rigid structural design cannot realize the self-adaptive adjustment of the separation parameters, so that the pretreatment effect is unstable, and the qualified air inlet cannot be continuously provided for RTO. The existing device also has the problems of high maintenance cost and poor operation continuity. Because the separation assembly is easy to be adhered and blocked by impurities, the separation assembly needs to be frequently stopped, disassembled and cleaned, so that the manual maintenance cost is increased, the waste gas treatment process is interrupted, and the continuity of industrial production is affected. The separation assembly of part of the device adopts an integrated design, and the separation assembly needs to be integrally disassembled during cleaning or replacement, so that the shutdown time is further prolonged. In addition, after liquid impurities which are not effectively separated enter RTO, transient pressure fluctuation can be generated by rapid vaporization in a high-temperature environment, the safety risk of equipment operation is increased, and cavity vibration or sealing failure can be caused in severe cases.
