Shops in the process of operation, need to discharge a large number of fumes and smoke, if not timely eliminated, it will cause serious pollution to people's health and the environment. Therefore, the store exhaust smoke introduced into the sewer has become an effective method, the following we will introduce the method of store exhaust smoke introduced into the sewer.

One, centralized induced draft system

Centralized induced draft system is the use of local exhaust hoods will be centralized exhaust fumes, and then through the pipeline will be introduced to the centralized fume fan. This method is suitable for restaurants, canteens, fast food restaurants and other stores.

Two, decentralized induced draft system

Decentralized induced draft system is also the use of local exhaust hoods to centralize the discharge of fumes, and then through the pipeline will be introduced into the fumes scattered fan, each exhaust hood corresponds to a fan. This method is suitable for stores with large kitchen areas or multiple kitchens.

Three, wet purification technology

Wet purification technology is to wash the fumes through the water, and then the washed water into the sewer. The advantage of this method is good purification effect, low energy consumption, low operating costs. But the disadvantage of this technology is that it requires a large amount of water, the discharge of wastewater is relatively large, causing adverse effects on the environment.

Four, dry purification technology

Dry purification technology is to filter out the soot through the filter, and then send the soot in the filter to the sewer. The advantage of this technology is that the purification effect is good, the discharge of wastewater is relatively small, but the operating cost is relatively high, and the filter needs to be replaced frequently.

Overall, the introduction of store fumes into the sewer is a more environmentally friendly and energy-saving solution. Different stores can choose different methods, according to their actual situation.
