The zeolite runner exhaust gas treatment system mainly consists of two parts: exhaust gas concentration system and exhaust gas incineration treatment system.

廢氣濃縮主要通過沸石轉(zhuǎn)輪實現(xiàn)，轉(zhuǎn)輪為圓形結(jié)構(gòu)，內(nèi)部均勻填充沸石，而沸石的主要成分是多孔的骨架型硅鋁酸鹽，其內(nèi)部分布著孔穴，具有對大小不一的分子進行選擇性吸附的特性，故沸石轉(zhuǎn)輪也被稱為分子篩。沸石轉(zhuǎn)輪在不同溫度下具有不同的吸附效率，故安裝轉(zhuǎn)輪的風箱根據(jù)轉(zhuǎn)輪的特性設(shè)置了3個分區(qū)：吸附區(qū)、脫附區(qū)、冷卻區(qū)。

The concentration of waste gas is mainly achieved through zeolite wheels, which have a circular structure and are uniformly filled with zeolite. The main component of zeolite is a porous framework type aluminosilicate, with pores distributed inside, which have the characteristic of selective adsorption of molecules of different sizes. Therefore, zeolite wheels are also known as molecular sieves. The zeolite wheel has different adsorption efficiency at different temperatures, so the wind box installed with the wheel is divided into three zones based on the characteristics of the wheel: adsorption zone, desorption zone, and cooling zone.

涂裝車間產(chǎn)生的廢氣通過匯總風道匯總后，經(jīng)風管傳輸?shù)睫D(zhuǎn)輪風箱進風口，廢氣在進入沸石轉(zhuǎn)輪之前，設(shè)置3道過濾器，用于將廢氣中含有的雜質(zhì)、顆粒去除，防止將沸石轉(zhuǎn)輪堵塞。

The exhaust gas generated in the painting workshop is collected through a collection duct and then transmitted to the inlet of the runner wind box through the duct. Before the exhaust gas enters the zeolite runner, three filters are installed to remove impurities and particles contained in the exhaust gas and prevent blockage of the zeolite runner.

車間廢氣經(jīng)過調(diào)溫調(diào)濕及過濾后，進入轉(zhuǎn)輪風箱的吸附區(qū)，大部分廢氣成分被轉(zhuǎn)輪吸附，少量廢氣成分隨著凈化后的廢氣被直接排放，轉(zhuǎn)輪在吸附的過程中不停地轉(zhuǎn)動，吸附區(qū)吸收了大量廢氣成分后轉(zhuǎn)動至脫附區(qū)，此時來自RTO的高溫煙氣通過與部分的車間廢氣混合達到250℃后通向脫附區(qū)，因為沸石轉(zhuǎn)輪在250℃高溫的情況下吸附效率較低，在吸附區(qū)吸附的廢氣成分在脫附區(qū)會重新被脫附下來，隨著高溫煙氣被輸送至RTO里進行廢氣焚燒處理，焚燒產(chǎn)生的煙氣一部分用于轉(zhuǎn)輪入口廢氣的升溫除濕，另一部分送至脫附區(qū)進行脫附。

After temperature, humidity, and filtration, the workshop exhaust gas enters the adsorption area of the rotary fan. Most of the exhaust gas components are adsorbed by the rotary fan, and a small amount of exhaust gas components are directly discharged with the purified exhaust gas. The rotary fan continuously rotates during the adsorption process. The adsorption area absorbs a large amount of exhaust gas components and then rotates to the desorption area. At this time, high-temperature flue gas from RTO is mixed with some workshop exhaust gas to reach 250 ℃ before leading to the desorption area, Due to the low adsorption efficiency of the zeolite wheel at a high temperature of 250 ℃, the waste gas components adsorbed in the adsorption zone will be re desorbed in the desorption zone. As the high-temperature flue gas is transported to the RTO for waste gas incineration treatment, some of the flue gas generated from incineration is used for heating and dehumidification of the exhaust gas at the inlet of the wheel, and the other part is sent to the desorption zone for desorption.

旋轉(zhuǎn)RTO由上至下可以分為3個部分：分風室、蓄熱室、燃燒室。蓄熱室里均勻分布著蜂窩狀陶瓷蓄熱體，在加熱期流過格孔的高溫煙氣將熱量傳遞給蜂窩陶瓷蓄熱體，在冷卻期，低溫的廢氣以相反的方向流過格孔并獲得熱量，形成高溫廢氣，所以陶瓷蓄熱體的通過性直接影響著廢氣處理效率及RTO設(shè)備運行能耗。

The rotating RTO can be divided into three parts from top to bottom: air distribution chamber, heat storage chamber, and combustion chamber. The honeycomb shaped ceramic heat storage body is evenly distributed in the heat storage chamber. During the heating period, the high-temperature flue gas flowing through the grid holes transfers heat to the honeycomb ceramic heat storage body. During the cooling period, the low-temperature exhaust gas flows in the opposite direction through the grid holes and obtains heat, forming high-temperature exhaust gas. Therefore, the trafficability of the ceramic heat storage body directly affects the efficiency of waste gas treatment and the energy consumption of RTO equipment operation.

故旋轉(zhuǎn)RTO在設(shè)計時考慮了蓄熱陶瓷體的吹掃功能。初的設(shè)計為在RTO旁邊設(shè)置吹掃風機，直接采用室外新風對蓄熱陶瓷進行吹掃，但設(shè)備運行時發(fā)現(xiàn)：

Therefore, the design of the rotating RTO takes into account the blowing function of the thermal storage ceramic body. The initial design was to install a blowing fan next to the RTO, directly using outdoor fresh air to blow the thermal storage ceramic. However, during equipment operation, it was found that:

1)因為室外新風溫度較低，吹入的冷風導(dǎo)致蓄熱陶瓷及燃燒室溫度降低，所以，設(shè)備運行時天然氣耗量較大，增加了能源成本;2)設(shè)備運行時，RTO進氣量與排氣量均衡，當吹掃風機補入部分風量時，破壞RTO內(nèi)部風平衡，且容易造成燃燒室內(nèi)部壓力增大。

1) Due to the low temperature of outdoor fresh air, the cold air blown in leads to a decrease in the temperature of the thermal storage ceramic and combustion chamber, resulting in a higher natural gas consumption during equipment operation and an increase in energy costs; 2) When the equipment is running, the intake and exhaust of RTO are balanced. When the blowing fan replenishes a portion of the air volume, it can disrupt the internal air balance of RTO and easily increase the pressure inside the combustion chamber.

故設(shè)備廠家對吹掃功能進行優(yōu)化，將吹掃風向進行改變，由原來的風機抽取室外新風對陶瓷蓄熱體進行正吹掃改為風機抽取RTO內(nèi)部氣體進行反向吹掃，將抽出來的煙氣經(jīng)風管引至RTO入口主風機之前，隨著濃縮廢氣再次補入RTO內(nèi)部，其優(yōu)點為：

Therefore, the equipment manufacturer has optimized the blowing function by changing the blowing direction. Instead of using the original fan to extract outdoor fresh air for positive blowing of the ceramic heat storage body, the fan will extract the gas inside the RTO for reverse blowing. The extracted flue gas will be directed through the air duct to the front of the main fan at the RTO inlet, and as the concentrated exhaust gas is replenished into the RTO, its advantages are:

1)抽出的煙氣隨后又補入RTO內(nèi)部，沒有能量損失，節(jié)省了天然氣等能源;2)吹掃風機抽出的煙氣隨后及時補入RTO，形成了一個內(nèi)循環(huán)，不會造成RTO內(nèi)部壓力增加，且風平衡穩(wěn)定。

1) The extracted flue gas is then fed into the RTO without energy loss, saving energy such as natural gas; 2) The flue gas extracted by the blowing fan is then promptly fed into the RTO, forming an internal circulation that does not cause an increase in internal pressure within the RTO, and the air balance is stable.
