Specific implementation manners

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below. All other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Embodiment 1: Please refer to Figures 1-12 , a pretreatment component for treating high-hydrogen tail gas, including a tank body main body 1, a sealed top cover 2, a sealed bottom cover 3, an intake pipe 5, a gas transmission pipe 6, a rotation control motor 7, a pretreatment filtering mechanism, and a treatment cooperation mechanism.

[0037] Here, a sealed top cover 2 is fixedly arranged at the top of the tank body main body 1 through bolts, a sealed bottom cover 3 is fixedly arranged at the bottom of the tank body main body 1 through bolts, and a gas transmission pipe 6 is communicated and arranged on one side of the tank body main body 1; among them, a rotation control motor 7 is arranged on the sealed top cover 2, the rotation control motor 7 is connected with a connecting rotating shaft 8, a fixed connecting disk 10 is fixedly arranged at the bottom end of the connecting rotating shaft 8, and the fixed connecting disk 10 is connected with the treatment cooperation mechanism; here, a support leg 4 is fixedly arranged at the bottom end of the sealed bottom cover 3, and the sealed bottom cover 3 is communicated with the intake pipe 5; the treatment cooperation mechanism is arranged in the tank body main body 1; here, a support disk body 31 is fixedly arranged inside the sealed bottom cover 3, a pretreatment filtering mechanism is arranged on the support disk body 31, and the support disk body 31 is communicated with the intake pipe 5.

[0038] Among them, the waste gas enters the tank body main body 1 from the intake pipe 5, and the particulate impurities in the gas are pretreated through the combined use of the pretreatment filtering mechanism and the treatment cooperation mechanism. After the treatment, the gas is output from the gas transmission pipe 6; in this process, the first filter cylinder 901 arranged on the sealed bottom cover 3 is fixedly arranged, and the second filter cylinder 1101 arranged is rotationally controlled by the rotation control motor 7 to filter and remove impurities from the incoming waste gas.

[0039] After the pretreatment, the waste gas enters the intelligent and efficient integrated system for volatile organic pollutants, and is introduced into the adsorber by the induced draft fan. The adsorber uses three towers for adsorption, with two adsorbing and one standby for adsorption treatment. The automatic control system of the equipment can be divided into time control and outlet detection control, and can be remotely monitored and controlled through data connection to the DCS center; the saturated adsorbent is regenerated by low-pressure steam. The regenerated gas phase is condensed by the condenser and collected in the oil-water separator. The condensate is recycled through the water separator to recover the materials, and after dehydration and qualification, it enters the workshop crude product tank, and the water phase goes to the waste water storage tank. After the steam regeneration is completed, spraying is used for cooling, and the spraying water is collected in the waste water storage tank. The waste water is treated by the water circulation system and then reused.

[0040] Afterwards, the wastewater generated by the gas treatment system is collected in the wastewater storage tank, and then treated by the wastewater adsorber to remove the dissolved organic matter in the wastewater. The treated wastewater is collected in the circulating water tank and used as the makeup water for the pre-treatment spray circulation evaporation and adsorbent cooling of the gas treatment system, and the remainder is used as industrial water makeup. After the adsorber becomes saturated, steam is used to blow off and regenerate the wastewater adsorber, and the blow-off tail gas is condensed by the condenser. The gas recovery liquid is transported to the gas treatment device for stratification or re-adsorption treatment. After the blow-off is completed, the circulating water in the circulating water tank is used to cool down the adsorber, and the wastewater is discharged into the wastewater collection tank.

[0041] The present invention mainly pre-treats the tail gas through the combined use of the pre-treatment filtering mechanism and the treatment cooperation mechanism. The waste gas enters the main body 1 of the tank from the intake pipe 5, and the particulate impurities in the gas are pre-treated through the combined use of the pre-treatment filtering mechanism and the treatment cooperation mechanism. Among them, double-layer filtration and impurity removal are carried out through the first filter cylinder 901 and the second filter cylinder 1101 provided.

And the auxiliary groove 909 provided on the side wall of the cleaning auxiliary cotton strip 908 has a simple collection and adhesion effect on particles and other impurities in the gas. Then it passes through the second filter cylinder 1101 for further filtration and impurity removal, and finally passes through the first filter cylinder 901 on the outside for filtration and impurity removal. The pretreated gas is then output from the gas transmission pipe 6 and enters the next processing step. During this process, the second filter cylinder 1101 is driven to rotate by the rotation control motor 7, and the bearing ring 1103 provided at the bottom of the second filter cylinder 1101 is inserted into the auxiliary placement groove 905 on the support disk body 31.
