??? 復(fù)合光催化泡沫金屬*納米復(fù)合技術(shù),整合納米光觸媒材料與泡沫鎳的優(yōu)良特性,在泡沫鎳基體上均勻負(fù)載一定量的納米TiO2而獲得的一種負(fù)載型光催化功能材料。TiO2光催化氧化是活性羥基(?OH)和其他活性氧化類物質(zhì)(?O2-，?OOH ，H2O2)共同作用的結(jié)果。在TiO2表面生成的?OH基團(tuán)反應(yīng)活性很高，具有高于有機(jī)物中各類化學(xué)鍵能的反應(yīng)能，加上?O2-，?OOH ，H2O2活性氧化類物質(zhì)的協(xié)同作用，能迅速有效地分解有機(jī)物。

（2）森林之源干式異味控制技術(shù)機(jī)理

??? 森林之源Vaportek臭味去除技術(shù)采用由三十多種天然植物提取液制成的臭味去除劑，該植物提取液包裹在單向透析膜（世界）中使用，由于透析膜具有單向滲透作用，在將Vaportek植物提取液除臭味粒子均勻分布于膜片表面，并利用空氣對(duì)流動(dòng)力帶出而迅速消除臭味的同時(shí)，不會(huì)吸入外在的其它物質(zhì)，永葆植物提取液的天然性。

??? 進(jìn)入空氣中的除臭微粒子可迅速主動(dòng)捕捉空氣中的臭味氣體分子，并將臭味粒子包裹住。而常見的臭氣分子大多為小分子有機(jī)物（酯類、醇類、芳烴類等），同時(shí)也包括部分無機(jī)小分子如臭氧、氨、硫化氫、碳?xì)漕惖?，它們通常在嗅覺細(xì)胞表面活性較高，刺激性較強(qiáng)，即使在各臭氣成分濃度均達(dá)標(biāo)排放的前提下，仍然具有*的嗅覺污染能力，也就是具有通常所說的低污染濃度、高臭氣強(qiáng)度的特性。VAPORTEK粒子為天然油性脫臭分子，該粒子通過分子間非極性相互作用與臭氣分子發(fā)生非共價(jià)結(jié)合，從而大大穩(wěn)定該類分子，降低其活性與刺激性。進(jìn)而，由于結(jié)合后比重的增加，通過沉降作用解決。此過程既不同于化學(xué)反應(yīng)過程而生成第三種物質(zhì)，也不同于掩蓋作用，不會(huì)造成二次污染，可*去除臭味。

在設(shè)備對(duì)其廢氣進(jìn)行處理的過程中，廢氣通過水洗箱后，使其中的洗滌液具有酸性和含有大量雜質(zhì)。如不及時(shí)地清洗這些腐蝕性物質(zhì)和雜質(zhì)，不僅會(huì)縮短水洗箱的壽命，而且將直接影響等設(shè)備的凈化效率。因此，為了更好的保護(hù)設(shè)備，讓設(shè)備更好的為我們所用，我們需要了解一下它該如何保養(yǎng)。

下面小編就具體說說做法，如下：

（1）每班班前須往水洗箱及副水箱加水，水應(yīng)清潔并加到規(guī)定的水位；

（2）使用過程中經(jīng)常檢查水位，使其保持在規(guī)定水位；

（3）每班結(jié)束時(shí)，應(yīng)放盡對(duì)廢氣凈化設(shè)備中水洗箱內(nèi)的洗滌液；

（4）定期檢查水洗箱是否滲漏、損壞，接頭是否松脫；

（5）定期用*水溶液清洗殘存的酸性物質(zhì)。

If the flow to be processed is below 5000Nm3/h, the regenerative system (RTO) is generally not applicable. This is because the high cost of the regenerative oxidizer (RTO) is generally inadequate to counteract the benefits of saving fuel and power consumption compared with the thermal incineration system. When the flow rate is greater than 50000Nm3/h, the thermal and thermal incineration system has serious economic drawbacks, because they will generate very high fuel costs. However, if a large amount of heat energy is needed in the process, a two level heat boiler can be used to offset high fuel costs, and the other is an emergency system for dealing with large flow of waste gas with little operation every year.

If the temperature of the waste gas is treated above 300 degrees centigrade, it is not suitable for the use of the regenerative system (RTO), which is because the high temperature treatment of the organic waste gas will greatly reduce the reliability and life of the reversing valve; in addition, at such a high temperature, the height of the construction of the RTO is not enough to offset the fuel and power consumption. The benefits are brought. If the temperature of the waste gas is over 500, the heat recovery incineration system is not better than the direct combustion system, because the gap between fuel consumption is too small and it is not enough to offset the investment cost of the increased heat recovery.

Direct fired oxidizer can handle hydrocarbons with the maximum concentration range from 1/1000000000 to pure hydrocarbon vapor. If organic waste gas concentration exceeds 25%, special measures should be taken to prevent tempering from oxidizer to exhaust gas source. The cost of this ability to deal with large range of elastic capacity is the high fuel cost of this type of oxidizer.

Special care must be taken when organic waste gas contains high concentration of organic acids (such as chlorine, fluorine, sulfur and halogen). They will cause serious corrosion to equipment or catalyst poisoning.

When organic waste gas contains tiny particles, special care must also be taken. For example, when the exhaust gas contains oil mist particles, they will gather in the cooler part of the pipeline and oxidizer, so the equipment needs cleaning regularly.

If two or more types of oxiders are suitable for you on the basis of the above principles, let's make a detailed economic analysis based on the cost of the primary investment and the operating cost of the equipment (catalyst, fuel, and electricity) to help you make the best choice. Choose. The discharge volume of organic waste gas, if the volume of organic waste gas to be treated is below 5000Nm3/h, the regenerative system (RTO) is generally not applicable. This is because the high cost of the regenerative oxidizer (RTO) is generally insufficient to counteract the benefits of saving fuel and power consumption compared with the heat recovery incineration system.

Organic waste gas treatment scrubber is a new type of gas purification equipment. It is produced on the basis of a floating packer gas purifier, which is widely used in the pretreatment of industrial waste gas purification, dust removal and so on. The purification effect is very good. Because its working principle is similar to the washing process, it is called scrubbing tower.

The washing tower consists of a tower body, a tray, a reboiler and a condenser. During the operation, the reboiler is usually heated by steam, and the condenser is heated by circulating water. The balance should be established before use, that is, to adjust the amount of evaporation and reflux by using steam and condensate, so that it can accumulate a certain thickness of liquid on the tray. In the course of using, we must control a liquid level, two temperature and two pressure difference and so on several main points. That is, the liquid level of the washing tower, the inlet temperature of the gas, the top temperature of the tower, the differential pressure between the towers (the difference between the inlet pressure of the washing tower and the pressure of the top of the tower), the difference of the pressure of the condenser (the difference between the top and the outlet pressure of the condenser).
