沸石轉(zhuǎn)輪濃縮-蓄熱式燃燒處理工藝主要由沸石轉(zhuǎn)輪濃縮（吸附區(qū)，脫附區(qū)，冷卻區(qū)），脫附系統(tǒng)，蓄熱式燃燒系統(tǒng)（RTO爐體，陶瓷蓄熱體，燃燒系統(tǒng)等）和控制系統(tǒng)等。

The zeolite wheel concentration thermal storage combustion treatment process mainly consists of zeolite wheel concentration (adsorption zone, desorption zone, cooling zone), desorption system, thermal storage combustion system (RTO furnace body, ceramic thermal storage body, combustion system, etc.), and control system.

吸附和脫附：沸石分子篩轉(zhuǎn)輪吸附和濃縮系統(tǒng)采用吸附，脫附和冷卻的連續(xù)過程來吸收和濃縮VOCs。沸石分子篩轉(zhuǎn)輪分為三個功能區(qū)：吸附區(qū)，脫附區(qū)和冷卻區(qū)。廢氣進入沸石分子篩轉(zhuǎn)輪的吸附區(qū)，VOCs被沸石分子篩吸附和去除，凈化后排放。通過約200°C的小風量的熱風處理，將吸附在分子篩轉(zhuǎn)輪中的VOCs脫附并濃縮在脫附區(qū)中。再生的沸石分子篩轉(zhuǎn)輪在冷卻區(qū)中冷卻，如此反復。

Adsorption and desorption: The zeolite molecular sieve rotary adsorption and concentration system adopts a continuous process of adsorption, desorption, and cooling to absorb and concentrate VOCs. The zeolite molecular sieve wheel is divided into three functional zones: adsorption zone, desorption zone, and cooling zone. The exhaust gas enters the adsorption zone of the zeolite molecular sieve wheel, and VOCs are adsorbed and removed by the zeolite molecular sieve before being purified and discharged. The VOCs adsorbed in the molecular sieve impeller are desorbed and concentrated in the desorption zone through a small air flow of about 200 ° C. The regenerated zeolite molecular sieve wheel is cooled in the cooling zone repeatedly.

蓄熱式燃燒：脫附的高濃度，小風量廢氣進入RTO處理系統(tǒng)，首先進入RTO蓄熱器A的陶瓷介質(zhì)層，陶瓷釋放熱量，溫度降低，而有機廢氣吸收熱量，溫度升高，廢氣離開蓄熱室，以較高的溫度進入氧化室。在氧化室中，有機廢氣被燃燒器加熱到設(shè)定的氧化溫度800℃以上，使其中的VOCs分解為二氧化碳和水，然后排出。廢氣流過蓄熱室A并進入氧化室進行氧化。凈化后的高溫氣體離開氧化室，進入蓄熱室B，釋放熱量，降溫并排出，蓄熱室B吸收大量熱量升溫，同時清掃蓄熱器 C室。循環(huán)完成后，入口閥和出口閥切換一次，然后進入下一個循環(huán)。廢氣進入蓄熱室B，蓄熱室C被排出，蓄熱室A被清掃。如此交替。由于廢氣已經(jīng)在蓄熱室中被預(yù)熱，因此大大降低了燃料消耗，并且大大降低了運行成本。

Regenerative combustion: The desorbed high concentration, low air volume exhaust gas enters the RTO treatment system and first enters the ceramic medium layer of RTO accumulator A. The ceramic releases heat and the temperature decreases, while the organic exhaust gas absorbs heat and the temperature increases. The exhaust gas leaves the heat storage chamber and enters the oxidation chamber at a higher temperature. In the oxidation chamber, the organic waste gas is heated by the burner to a set oxidation temperature of over 800 ℃, causing the VOCs in it to decompose into carbon dioxide and water, and then discharged. The exhaust gas flows through the heat storage chamber A and enters the oxidation chamber for oxidation. The purified high-temperature gas leaves the oxidation chamber, enters the heat storage chamber B, releases heat, cools down and is discharged. The heat storage chamber B absorbs a large amount of heat and heats up, while cleaning the heat storage chamber C. After the cycle is completed, switch the inlet valve and outlet valve once before entering the next cycle. The exhaust gas enters the heat storage chamber B, the heat storage chamber C is discharged, and the heat storage chamber A is cleaned. So alternating. Due to the preheating of the exhaust gas in the heat storage chamber, fuel consumption is greatly reduced and operating costs are greatly reduced.
