Nowadays, human beings are increasingly demanding the surrounding living environment. The odor of the municipal sewage treatment plant is increasingly being affected by the surrounding residents. Nowadays, human beings are increasingly demanding the surrounding living environment. Municipal sewage treatment plant The odor effect is increasingly being paid attention to by the surrounding residents. The odor generated by the municipal sewage treatment plant in the daily operation process is one of the secondary elements of the destruction of the environment, which indirectly jeopardizes the weakness of the residents around the sewage treatment plant. And the quality of life, so the human society is increasingly demanding the results of the odor solution generated by the municipal sewage treatment plant. The FRP gas hood is solving these problems.
The collecting hood of the sump of the sump is a very important part of the odor solution. In the actual project, a gas hood that is economical, suitable, beautiful and easy to operate and protect the equipment of the plant is selected. To solve one of the important tasks of the odor generation generated by the factory, the construction mode of the sealing cover affects the size of the sealed space, the size of the sealed space determines the amount of odor to be solved, and the size of the odor to be solved is indirectly determined. Odor collecting pipelines and odors solve the fragmentary investment, so the proper sealing structure can effectively increase the amount of odor to be solved, thereby reducing the investment of the municipal sewage treatment plant for odor management, and at the same time securing the odor source. The stench does not leak, and achieves a good solution.
Nowadays, there are many kinds of sealing forms for the odor source of the municipal sewage treatment plant. A FRP gas hood is added above the sewage pool. At this time, the exhaust gas generated in the sewage pool is cut off from the air. An air outlet is added to the outer surface of the gas collecting hood, and a ventilation pipe is installed. The exhaust gas enters the exhaust gas pollution tower through the ventilation pipe, so as to increase the exhaust gas collection. In front of the pollution tower, the FRP fan is installed, and the exhaust gas is sucked into the pollution tower by the fan. The exhaust gas is sprayed in two stages in the tower. If the exhaust gas is acidic, it is absorbed by the lye circulation. If the exhaust gas is alkaline, it adopts the acid circulation spray absorption. The exhaust gas solution efficiency is over 90%, and the emission reaches the national independence specification.
