The baffle can be dismantled in the side setting of horizontal rotary drum 3, can dismantle and set up the preformed hole in the baffle, and the size of preformed hole is the same with 3 import sizes of horizontal rotary drum. The number of the horizontal drums 3 is double.
A horizontal rotary drum device for large-air-volume paint spraying waste gas comprises a pretreatment unit, an adsorption concentration unit and a combustion unit. The large-air-volume spray painting waste gas sequentially enters the pretreatment unit and then reaches the rotating wheel adsorption concentration unit, and is exhausted after reaching the standard after being completely adsorbed. The concentrated organic matter meets the emission requirement after passing through the combustion unit. The air quantity which can be treated by the rotary wheel adsorption concentration unit is about 200000m3/h, the adsorption concentration unit with a novel structure can be adopted, the space layout is rationalized, and the treatment application of the paint spraying waste gas with the ultra-large air quantity is realized in the limited space.
The pretreatment adopts the multi-stage filter 1, can effectively intercept paint slag particles in the paint spraying waste gas, and protects the rotary drum adsorption concentration system.
By adopting the horizontal rotary drum 3, the waste gas enters the horizontal rotary drum 3 from the side surface and is discharged from openings at two sides. When the air volume exceeds 200000m3/h, a series connection form of two sets of horizontal drums 3 can be adopted, and the length can be expanded, so that the investment on equipment cost is saved, and meanwhile, a more optimized layout can be realized. The paint spraying waste gas with the air volume of 42 ten thousand m3/h can be treated by adopting a single-layer 2-rotating-barrel combination, and the paint spraying waste gas with the air volume of 84 ten thousand m3/h can be treated by adopting a double-layer 4-rotating-barrel combination. Large air volume for treatment and saving the initial equipment investment cost.

Two-to-one VOCs adsorption concentration treatment system is reasonably arranged in a limited space range. The horizontal rotary drum 3 is applied to treatment of large-air-volume paint spraying waste gas, when several sets of rotary drums are required to be arranged in parallel according to the previous model selection, only several sets of horizontal rotary drums are required to be transversely connected in series or longitudinally stacked for the large-air-volume paint spraying waste gas.
The horizontal rotary drum 3 is internally provided with an adsorption material which is a zeolite molecular sieve, and has the advantages of high adsorption speed, large adsorption capacity, small loading capacity and the like. Structurally, the horizontal rotary drum 3 only has two subareas, namely an adsorption area and a desorption area, and does not have a cooling area; the horizontal drum 3 on the material adopts built-in zeolite modules, the zeolite content of each module is up to more than 75 percent, and the zeolite with low specific heat capacity is adopted to load the material. The application result shows that the horizontal rotary drum 3 has higher adsorption efficiency which can reach 98 percent at most, and has better concentration capability on the organic waste gas with the same parameters, the maximum concentration multiplying power can reach 60 times, and the concentration capability is about 1.5-2 times of that of the same rotary wheel. The pretreatment can be deeply designed according to components contained in the spray painting waste gas, so that the components such as particles, viscous substances, oil mist and the like in the waste gas are effectively removed, and the zeolite rotary drum is protected from being blocked.
The large-air-volume low-concentration spray painting waste gas passes through the adsorption area in the horizontal rotary drum 3, VOC in the gas is adsorbed by the zeolite molecular sieve in the adsorption area, and the exhaust reaches the standard after purification.
The molecular sieve adsorbing the VOC in the adsorption zone enters the desorption zone through the rotation of the rotary drum. Introducing high-temperature small-air-volume gas into the desorption area to desorb the VOC adsorbed by the adsorption area, and then introducing the VOC into subsequent treatment equipment from an outlet of the desorption area.
The molecular sieve for adsorbing the VOC recovers the adsorption capacity after high-temperature desorption in the desorption area and then rotates to the adsorption area to begin to adsorb the VOC in the gas to be treated. Thus, the whole system can continuously and circularly purify the air to be treated and concentrate the VOC.
The combustion unit may take the form of catalytic combustion, regenerative combustion, or the like. High-concentration waste gas is decomposed by high-temperature oxidation and then is exhausted into a chimney together with the gas absorbed by the rotary drum.
The horizontal rotary drums 3 can be connected in series in the transverse direction and the longitudinal direction, the number of the series connection is not limited to 1 set, and the number of the series connection depends on the initial concentration and the emission requirement of the waste gas;
the system layout can arrange the adsorption fan and the horizontal rotary drum up and down for two sets of rotary drums and one combustion unit system, so that the floor area is saved, the structure is compact, and the layout is reasonable.
And a PLC program is adopted to complete data analysis and automatic control through monitoring the temperature, pressure and other data of the system.
The application specific method comprises the following steps:
the large-air-volume low-concentration spray painting waste gas is pretreated by the multistage filter 1 to remove particles, viscous substances and the like in the waste gas, wherein the grade of the filter is determined according to the working condition of the waste gas at the front end, and the filtering grade is not lower than F9, so that the service life of the zeolite molecular sieve is ensured. The filtered organic waste gas is sent to the horizontal rotary drum 3 through the adsorption fan 2. VOCs in the waste gas are adsorbed by the zeolite molecular sieve, and the waste gas is purified to meet the emission standard and is discharged into a chimney 5. The zeolite molecular sieve adsorbs organic components in the waste gas, the zeolite molecular sieve is transferred to a rotary drum desorption area along with the rotation of the horizontal rotary drum 3, the adsorbed VOCs are swept and desorbed by the low-air-volume high-temperature gas to form high-concentration low-air-volume concentrated gas, and the gas is sent to a combustion unit by a desorption fan and a main fan to be subjected to oxidative decomposition, so that the purification purpose is achieved.
