不同类型有机物的光催化降解半导体光催化剂大多是n型半导体材料(当前以TiO2使用***广泛)，具有区别于金属或绝缘物质的特别的能带结构，即在价带和导带之间存在一个禁带。由于半导体的光吸收阈值与带隙具有公式K=1240/Eg(eV)的关系，因此常用的宽带隙半导体的吸收波长阈值大都在紫外区域。
      在光照下，如果光子的能量大于半导体禁带宽度，其价带上的电子(e-)就会被激发到导带上，同时在价带上产生空穴(h+)。当存在合适的俘获剂、表面缺陷或者其他因素时，电子和空穴的复合得到***，就会在催化剂表面发生氧化—还原反应。
     价带空穴是良好的氧化剂，导带电子是良好的还原剂，在半导体光催化反应中，一般与表面吸附的H2O、O2反应生成˙OH和超氧离子O2-，能够把各种有机物直接氧化成CO2、H2O等无机小分子，电子也具有强还原性，可以还原吸附在其表面的物质。激发态的导带电子和价带空穴能重新合并，并产生热能或其他形式散发掉。
      氧化性强：
半导体光催化具有氧化性强的特点，对臭氧难以氧化的某些有机物如、四氯化炭、、都能有效地加以分解，所以对难以降解的有机物具有特别意义，光催化的有效氧化剂是羟基自由基（OH-）和超氧离子自由基（O2-、0-），其氧化性高于常见的臭氧、***、次氯酸等。
      ***节能：
光催化氧化利用人工紫外线灯管产生的真空波紫外光作为能源来活化光催化剂，驱动氧化—还原反应，电能消耗低，而且光催化剂在反应过程中并不消耗，利用空气中的氧作为氧化剂，有效地降解******废臭气体、节约能源成为光催化节约能源的特点。

Due to the relati***hip between the optical absorption threshold of semiconductors and the band gap with formula K=1240/Eg (eV), the absorption w***elength threshold of the commonly used broadband gap semiconductors is mostly in the ultr***iolet region.
In light, if the energy of the photon is greater than the width of the semiconductor band, the electron (e-) on the valence band is excited to the guide band, and a hole (h+) is produced on the valence band. When there are suitable trapping agents, surface defects, or other factors, the recombination of electr*** and holes is suppressed, and the oxidation - reduction reaction will occur on the surface of the catalyst.
The valence band hole is a good oxidizer. The conduction band electron is a good reducing agent. In the semiconductor photocatalytic reaction, the reaction of H2O and O2, which is adsorbed on the surface, produces OH and O2-, which can directly oxidize various organic compounds into ***all inorganic molecules such as CO2, H2O and so on. The electr*** also h***e strong reducibility and can be reduced to them by reduction. A surface material. The conduction band electr*** and valence band holes in the excited state can be recombined and generate heat or other forms.
Strong oxidation:
Semiconductor photocatalysis has the characteristics of strong oxidation, which can be effectively decomposed for some organic compounds, such as four chlorinated carbon, which are difficult to oxidize by ozone, so it is of special significance to the difficult to degrade organic matter. The effective oxidizing agent for photocatalytic oxidation is the hydroxyl radical (OH-) and the superoxide radical (O2-, 0-), and its oxidation Sex is higher than ozone, hydrogen peroxide, hypochlorite and so on.
High efficiency and energy s***ing:
The photocatalytic oxidation uses the vacuum ultr***iolet light produced by the artificial ultr***iolet lamp as energy to activate the photocatalyst, which drives the oxidation reduction reaction, the energy c***umption is low, and the photocatalyst is not c***umed during the reaction process, and the oxygen in the air is used as the oxidant to effectively reduce the toxic and harmful odor gas and s***e energy. It is the characteristic of photocatalytic energy s***ing.
The operation and maintenance is simple:
The equipment is simple and simple to operate. It only needs to set up a fan, and no need for personal management and routine maintenance.

Working principle of sprinkler tower
The acid fog waste gas is introduced into the purifying tower by the wind pipe. The gas and liquid two phase absorption neutralization reaction is carried out by the exhaust gas and the sodium hydroxide absorption liquid. The acid mist exhaust gas is purified and then drained into the atmosphere by the dehydration of the mist removal plate and the mist eliminator. The absorption liquid is pressurized by the pump at the bottom of the tower and then sprayed down at the top of the tower. Finally, it is recycled to the bottom of the tower for recycling. After purification, the waste gas of acid mist reaches the discharge standard of local discharge standard in Guangdong, and is lower than the discharge standard.
