Efficient capturing and centralized discharging system of multi-point source emitted pollutants

Abstract

The invention discloses an efficient capturing and centralized discharging system of multi-point source emitted pollutants. The efficient capturing and centralized discharging system comprises at least one smoke exhaust branch pipe (4), at least one smoke collecting hood (5), at least one system smoke exhaust horizontal main pipe (3), a system smoke exhaust main pipe (2), a smoke exhaust fan (1) and at least one control device (6). The system smoke exhaust horizontal main pipes (3) are connected with the smoke collecting hoods (5) through the smoke exhaust branch pipes (4). The smoke exhaust fan (1) is connected with the system smoke exhaust horizontal main pipes (3) through the system smoke exhaust main pipe (2). The control devices (6) are located in the smoke exhaust branch pipes (4). Fence arranging, negative-pressure expanding design, reasonable air supplementing and the like are carried out for the smoke collecting hoods, the pollutants are effectively controlled in the smoke collecting hoods, and the pollutants are prevented from being diffused in a whole workshop. According to the system, the smoke collecting hoods are reasonably controlled, and the effects that the pollutants are collected when emitted, and are not collected when stopping emitting can be achieved.

Description

technical field [0001] The invention belongs to the technical field of industrial ventilation, and relates to a system for efficient collection and centralized discharge of pollutants. Background technique [0002] In some industrial places such as rubber vulcanization workshops and textile factories, because the emission sources of pollutants are not concentrated, the emission of pollutants changes with time, that is, multi-point sources in space and scattered in time. In industry, comprehensive ventilation system or local ventilation system is often used for capture and discharge. The comprehensive ventilation system not only has a large ventilation volume and low emission concentration, but also the pollutants are mixed in the whole workshop, resulting in a high concentration of pollutants in the working area and affecting the health of workers. When the local ventilation system is used, on the one hand, the existing local exhaust hoods are often limited by machinery and...

Problems solved by technology

The comprehensive ventilation system not only has a large ventilation volume and low emission concentration, but also the pollutants are mixed in the whole workshop, resulting in a high concentration of pollutants in the working area, which affects the health of workers

When the local ventilation system is used, on the one hand, the existing local exhaust hoods are often limited by machinery and technological processes, and cannot well control the emission source of pollutants; on the other hand, each emission source is equipped with an exhaust fan, and the initial Large investment, high operating and management costs
