Waterproof and dust-settling air exhausting device

Abstract

The invention relates to the technical field of environmental protection equipment, in particular to a waterproof and dust-settling air exhausting device. The waterproof and dust-settling air exhausting device comprises a shell, a guide structure, an air exhausting pipe and a drainage pipe, wherein the guide structure comprises an inversed upper conical barrel, a lower conical barrel and a lining plate and is connected with the shell through a connecting plate and a base plate; the lower part of the shell is welded with the air exhausting pipe through reinforcing ribs; the shell is further connected with a flow guide pipe through reinforcing ribs; and the shape of the shell is matched with that of the guide structure. The waterproof and dust-settling air exhausting device is used at the tail of an air exhausting pipe, not only can be waterproof, but also collect dust in tail gas on the premise of not affecting the air exhausting effect, and pollution is reduced. When the device is designed, running situations of a system and components in smoke should be considered, and therefore, different materials such as common materials, anti-corrosion materials or high-temperature-resistant materials and the like can be used according to the different situations.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a waterproof and dust-reducing exhaust device. Background technique [0002] The chimney effect is the result of the joint action of the thermal pressure formed by the indoor and outdoor temperature difference and the outdoor wind pressure, usually the former is the main one, and the thermal pressure value is proportional to the air density difference generated by the indoor and outdoor temperature difference and the height difference of the air inlet and outlet. The higher the indoor temperature is than the outdoor temperature, the taller the building is, the more obvious the chimney effect will be. Its main functions include smoking and pulling out fires, exhaust gas, and improving combustion conditions. It is the oldest, most important, and widely used anti-pollution device one. [0003] In modern industrial production, exhaust devices similar to ch...

Problems solved by technology

Today, as environmental protection is getting more and more attention from the country, although there are various dust collection equipments, it is inevitable that some dust will be brought out along with the exhaust pipe to discharge the flue gas, causing a certain amount of dust pollution.
