光催化除臭设备的工艺技术

1、光催化除臭设备水喷雾方法:水喷雾过程已广泛应用于空气污染治理,也被使用在喷涂过程中,如水冷壁内阁是一个例子,其原理是通过水喷涂废气,水溶性或大型粒子从废气成分安定下来,实现污染物和清洁气体分离的目的。其优点是水方便,同时可以重用过滤后,降水,最大限度地减少浪费水资源,水喷雾治疗大粒子成分有相当高的效率,通常用作预处理废气处理。
1. Water spray method for photocatalytic deodorization equipment: water spray process has been widely used in air pollution control, and is also used in the process of spraying, such as water cold wall cabinet is an example, the principle is to spray waste gas through water, water solubility or large particles to settle down from the waste gas components to achieve the purpose of separating pollutants and clean gas. Its advantages are water convenient, and can be reused after filtering, precipitation, and the maximum reduction of waste water resources. Water spray treatment of large particles is quite efficient, usually used as pretreated waste gas treatment.
2,工业废气处理冷凝复苏方法:直接冷凝废气吸附浓缩后冷凝,或冷凝分离回收有价值的有机物质。该方法用于高浓度、低温度、低废气处理的风量。但这大投资,能源消耗和运行成本高,因此没有特殊需要,一般不使用这种方法。喷淋吸收方法:废气处理可分为化学吸收和物理吸收,但“三苯”废气化学活性较低,一般不使用化学吸收。物理吸收如此之低挥发性液体吸收剂,它有较高的亲和力和吸收组件,吸收饱和后加热解析冷却后重用。该方法用于大体积、低温度、低浓度的废气。复杂的设备,投资,吸收液体的选择是困难的,有二次污染。

2, industrial waste gas treatment and condensation recovery methods: direct condensation of waste gas adsorption condensation, condensation, or condensation separation and recovery of valuable organic substances. The method is applied to the air volume of high concentration, low temperature and low waste gas treatment. But this big investment has high energy consumption and running cost, so there is no special need, and this method is not generally used. Spray absorption method: waste gas treatment can be divided into chemical absorption and physical absorption, but the "three benzene" exhaust gas has low chemical activity and generally does not use chemical absorption. The physical absorption of such a low volatile liquid absorbent has high affinity and absorption components. After absorption saturation, it is reused after heating and cooling. The method is applied to large volume, low temperature and low concentration waste gas. Complex equipment, investment and liquid absorption are difficult to choose, and there are two times of pollution.
3、光催化除臭设备直接燃烧法:使用辅助燃料如天然气或燃料燃烧热释放将混合气体加热到一定的温度(700 - 700℃),居民,可燃有害气体燃烧。简单的流程,减少设备投资,但能耗大,运行成本高。
3. Direct combustion method of photocatalytic deodorizing equipment: using auxiliary fuel, such as natural gas or fuel combustion heat release, heating the mixed gas to a certain temperature (700-700 degrees C), residents, combustible harmful gas burning. Simple process, reduce equipment investment, but high energy consumption and high running cost.
4、喷雾催化燃烧方法:废气处理后废气加热到200 ~ 300℃催化床燃烧、净化的目的。低能耗、高纯化率,无二次污染、操作方便简单的过程。适合高温、高浓度有机废气处理,不适合低浓度、大风量的有机废气处理。
4, spray catalytic combustion method: exhaust gas treatment of exhaust gas heated to 200 ~ 300 C catalytic bed combustion and purification purposes. Low energy consumption, high purification rate, no two pollution, easy operation and simple process. It is suitable for the treatment of high temperature and high concentration organic waste gas, and is not suitable for organic waste gas treatment with low concentration and large air volume.
