Acid-base scrubber absorption

The washing tower is an absorption tower. Using the gas-liquid mass transfer theory, one or several components are washed down to achieve the purpose of purifying the product. None of the equipment is fixed in size and needs to be based on your washing requirements and materials. How much, operating pressure, tower structure, operating elasticity and material properties to determine the process size. The working principle of acid scrubber (wet scrubber) is based on acid and alkali neutralization. Generally, chemicals that are relatively soluble in water are generally treated. Sodium hydroxide, pH is controlled at 7 ~ 9, alkaline waste gas is added with sulfuric acid, pH is controlled at 4 ~ 6.

Product Principle

2015112639337401.jpgThe contact between gas and liquid parts separates and purifies the organic waste gas from the contaminated liquid. Adopt gas-liquid reverse absorption treatment, that is, the liquid is sprayed down from the top of the tower in the form of water mist (or droplet). Exhaust gas is contacted by the tower (reverse flow) to achieve the purpose of gas-liquid contact; this treatment method can cool the exhaust gas, remove particulate matter and absorb part of the exhaust gas components that are easily soluble in water.

Features

1. In sewage treatment plants, there are many applications. The specific water spray absorption tower developed by our company in cooperation with the sewage company has been applied in many local large sewage treatment plants, and its absorption of dust and specific waste gas generated by the sewage are very good. Good absorption and treatment effect, and the overall treatment effect applied has been verified by exact results.

2. It can be applied in some high-temperature gas, large-particle organic waste gas, and high-concentration waste gas places. It can have a good effect of cooling down and removing large particulate matter with a cyclone tower or a water washing tower.

3. In some specific places, a specific absorption liquid can be added to the spray tower to neutralize the reaction with the exhaust gas, thereby improving the absorption and purification effect of the exhaust gas. Good absorption liquid has good absorption performance. , While reducing operating costs, it can also be applied to a variety of VOCs exhaust gas absorption.

4. After the front end absorbs the effect, the rear end can be equipped with post-processing equipment to further process and capture the malodorous gas.

Installation and case

1. When installing a pp acid mist purification tower, install it on a concrete foundation that is more than 150mm above the ground, and pumps and fans must be used as another concrete foundation in accordance with requirements.

2. Be careful not to damage the body and components when transporting and installing the acid mist purification tower.

3. If the pp acid mist purification tower is used outdoors, anti-freezing measures should be taken on the bottom pool components of the tower body in winter.

4. When using, turn on the exhaust water purification tower to turn on the circulating water pump for two to three minutes, and then start the blower. When stopping, stop the blower for one to two minutes, and then stop the circulating water pump.

5. Regularly check the purification degree of the gas in the pool at the bottom of the tower and the exhaust port according to the conditions of use. If it exceeds the standard, replace the absorption liquid in the bottom pool.

6. It is best to do maintenance once a year and a half to two years and clean it.
