沸石轉(zhuǎn)輪設(shè)備是治理大氣污染的一種氣體,在我們生活中因為生活節(jié)奏的加快,空氣也愈演愈烈變得不太好了。同樣的沸石轉(zhuǎn)輪設(shè)備能減少涂裝行業(yè)的成本。沸石轉(zhuǎn)輪設(shè)備每轉(zhuǎn)一輪吸附處理確定流量的廢氣,且每輪均控制通入高溫脫附區(qū)內(nèi)的熱空氣流量為送入濃縮轉(zhuǎn)輪的吸附區(qū)的廢氣流量的L/L(Tl/3),以使熱空氣中的VOC成分濃度為廢氣中的VOC成分濃度的310倍。
Zeolite rotary equipment is a type of gas used to control atmospheric pollution. In our daily lives, due to the accelerated pace of life, the air has become increasingly fierce and not very good. The same zeolite runner equipment can reduce costs in the coating industry. The zeolite rotary equipment adsorbs and processes waste gas with a certain flow rate every round, and controls the hot air flow rate into the high-temperature desorption zone to be L/L (Tl/3) of the waste gas flow rate sent into the adsorption zone of the concentration rotary, so that the VOC concentration in the hot air is 310 times that of the VOC concentration in the waste gas.
一、催化劑全部失活:使催化劑失活的毒物包括快和慢速作用毒物兩大類??熳饔枚疚镏饕蠵、As等,慢速作用毒物有Pb、Zn等。通常情況下,沸石轉(zhuǎn)輪的催化劑失活是由于毒物與活性組分化合或熔成合金。對于快作用毒物來說,即使只有微量也能使催化劑失活。
1、 Deactivation of all catalysts: The toxins that cause catalyst deactivation include two categories: fast and slow acting toxins. Fast acting toxins mainly include P, As, etc., while slow acting toxins include Pb, Zn, etc. Usually, the deactivation of catalysts in zeolite wheels is due to the differentiation and fusion of toxins and active components or the formation of alloys. For fast acting toxins, even a small amount can deactivate the catalyst.
二、沉積覆蓋活性中心:不飽和化合物的存在可導(dǎo)致炭沉積,此外,陶瓷粉塵、鐵氧化合物及其他顆粒物堵塞活性中心后,也會影響催化劑的吸附與解吸能力,導(dǎo)致催化劑活性下降。
2、 Deposition covers the active center: The presence of unsaturated compounds can lead to carbon deposition. In addition, ceramic dust, ferrite, and other particulate matter blocking the active center can also affect the adsorption and desorption ability of the catalyst, leading to a decrease in catalyst activity.
三、控制催化反應(yīng):鹵素和硫的化合物易與活性中心結(jié)合,但這種結(jié)合是比較松弛、可逆且暫時性的,當(dāng)廢氣中的這類物質(zhì)被去掉后,沸石轉(zhuǎn)輪的催化劑活性可以恢復(fù)。
3、 Control catalytic reaction: Halogen and sulfur compounds are prone to binding with active centers, but this binding is relatively relaxed, reversible, and temporary. When these substances are removed from the exhaust gas, the catalytic activity of the zeolite runner can be restored.
在應(yīng)用RTO的過程中,可以達到相應(yīng)的節(jié)能減排作用,對刷涂布機進行全部的優(yōu)化,對有用廢氣的濃度進行處理,減少總排量,且設(shè)備的損耗較低,可以減少資金的投入,節(jié)能效果較為明顯。例如:在有用廢氣中VOCS濃度大的時候,RTO廢氣治理設(shè)備就會利用印刷涂布烘干箱對其進行全部的處理,在作用之后,可以生成新鮮的空氣,減少對各類能源的損耗,逐漸提升工作效果,降低成本的支出,提升企業(yè)的經(jīng)濟效益,發(fā)揮RTO應(yīng)用作用。
In the process of applying RTO, corresponding energy-saving and emission reduction effects can be achieved. The brush coating machine can be fully optimized, and the concentration of useful exhaust gas can be treated to reduce the total displacement. Moreover, the equipment loss is low, which can reduce capital investment and achieve significant energy-saving effects. For example, when the concentration of VOCS in useful waste gas is high, RTO waste gas treatment equipment will use a printing coating drying box to fully treat it. After operation, it can generate fresh air, reduce the loss of various energy sources, gradually improve work efficiency, reduce cost expenditures, improve the economic efficiency of the enterprise, and play the role of RTO application.
沸石轉(zhuǎn)輪設(shè)備的主體是裝有吸附劑的轉(zhuǎn)輪,分為吸附區(qū)、循環(huán)區(qū)和冷卻區(qū)三個區(qū)。廢氣由鼓風(fēng)機引入吸附區(qū),吸附有用污染物,凈化后排放。然后,吸附劑旋轉(zhuǎn)到再區(qū)域。在與高溫空氣接觸的過程中,揮發(fā)性有用化合物被脫附,隨循環(huán)空氣流出,吸附劑被回收。回收的吸附劑被冷卻區(qū)冷卻,然后旋轉(zhuǎn)到吸附區(qū)進行再吸附。隨著轉(zhuǎn)輪的旋轉(zhuǎn),吸附劑被周期性地吸附、脫附和冷卻,以凈化廢氣。轉(zhuǎn)輪吸附濃縮+RTO后處理裝置:用于廢氣的處理;特別適用于風(fēng)量大、濃度低的場合,包括印刷、大型噴涂車間、家具、芯片、液晶LED行業(yè)等生產(chǎn)場所。
The main body of the zeolite rotary equipment is a rotary wheel equipped with adsorbent, which is divided into three zones: adsorption zone, circulation zone, and cooling zone. The exhaust gas is introduced into the adsorption zone by a blower to adsorb useful pollutants, which are then purified and discharged. Then, the adsorbent rotates to another region. During contact with high-temperature air, volatile useful compounds are desorbed, flowing out with the circulating air, and the adsorbent is recovered. The recovered adsorbent is cooled by the cooling zone and then rotated to the adsorption zone for re adsorption. As the wheel rotates, the adsorbent is periodically adsorbed, desorbed, and cooled to purify the exhaust gas. Rotary adsorption concentration+RTO post-treatment device: used for waste gas treatment; Especially suitable for occasions with high air volume and low concentration, including printing, large spraying workshops, furniture, chips, LCD LED industries and other production sites.
沸石轉(zhuǎn)輪可以利用空氣直接進行脫附,使用氮氣進行脫附起先我們要從氣體的成分來說起來,空氣中含有易燃的氧氣,催化燃燒室是在260攝氏度-420攝氏度之間進行高溫反應(yīng)的場所,如果操作不當(dāng)容易引起火災(zāi),而氮氣是一種惰性氣體,不易燃燒,所以使用氮氣進行脫附是比較理想的選擇。氮氣本身是惰性氣體,不參與燃燒,設(shè)備的五大穩(wěn)定系統(tǒng)中就有氮氣降溫這一項穩(wěn)定措施,如果脫附溫度過高,就會利用氮氣進行降溫,確定設(shè)備的穩(wěn)定運行。
Zeolite wheels can be directly desorbed using air. When using nitrogen for desorption, we need to start with the composition of the gas. The air contains flammable oxygen, and the catalytic combustion chamber is a place where high-temperature reactions occur between 260 ° C and 420 ° C. Improper operation can easily cause a fire. Nitrogen is an inert gas that is not easily combustible, so using nitrogen for desorption is an ideal choice. Nitrogen itself is an inert gas and does not participate in combustion. Among the five stable systems of the equipment, nitrogen cooling is a stabilizing measure. If the desorption temperature is too high, nitrogen will be used to cool down and ensure the stable operation of the equipment.
