Energy-saving and reliable dust collecting pipe network system

Abstract

The invention discloses an energy-saving and reliable dust collecting pipe network system, which includes a dust removing fan, a dust collecting main pipe, dust collecting branch pipes and valves I. The outlet end of the dust collecting main pipe communicates with an air inlet of the dust removing fan, the dust collecting main pipe is connected with at least two dust collecting branch pipes in parallel, the valves I are installed on the dust collecting branch pipes, the dust collecting branch pipes are used for sucking to-be-captured dusty gas, and the dust collecting main pipe is further connected with a clean air pipe for air suction. According to the energy-saving and reliable dust collecting pipe network system, in a traditional dust collecting pipe network system, the clean air pipe is additionally arranged to supply high-speed clean air flow, thus pipe blocking caused by dust accumulation in the pipe can be avoided, the valve is opened for the dust collecting branch pipes required for dust collecting and closed for the dust collecting branch pipes without dust collecting, and in the way, the efficiency of dust collecting is improved; and meanwhile, the energy-saving and cost-reducing action is achieved, the problems of noise, vibration, failure and multiple potential safety hazards caused by regular opening of dust collecting branch pipes in the traditional dust collecting pipe network system are solved, and the whole energy-saving and reliable dust collecting pipe network system has the characteristics of simple structure, energy saving and consumption reduction, high dust collecting efficiency, and safety and reliability.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, and in particular relates to an energy-saving and reliable dust collection pipe network system with simple structure, energy saving and consumption reduction, high dust collection efficiency, safety and reliability. Background technique [0002] In the process of industrial production, the dust treatment in industrial waste gas mainly adopts the process of "dust removal". In order to effectively capture dust and reduce operation and maintenance costs, the dust removal facility site usually adopts multi-point capture and negative pressure inside the dust removal facility. And set dust collection pipes and hoods at the points to be caught to capture and collect the dust on the spot. Due to the long production line of the dust removal and capture site, the adjustment changes and differences in production conditions, it often involves huge capture points and complex negativ...

Problems solved by technology

Due to the long production line of the dust removal and capture site, the adjustment changes and differences in production conditions, it often involves huge capture points and complex negative pressure capture pipe networks and control systems, and the multiple dust collection branch pipes of the conventional dust collection pipe network It is always open during the working process, not only the dust removal fan has to run at full speed throughout the whole process, resulting in the power consumption of the dust removal fan being basically unchanged, the energy consumption of the dust collection system is huge, and the resulting noise, vibration, failure points and potential safety hazards The number of points also increases, which brings many unfavorable factors to production

Although there are also valves installed on the dust collection branch pipe to adjust or even close the dust collection branch pipe, so as to avoid the problems of noise, vibration and safety hazards caused by normal opening, but if multiple dust collection branch pipes are closed due to process adjustment, it will lead to The corresponding dust collection pipe is blocked due to dust accumulation due to lack of air flow or insufficient air flow; in addition, in order to save energy and reduce consumption, in the prior art, the speed of the dust removal fan is also adjusted according to the air pressure and flow rate in the pipe, although the dust collection can be completed. Demand and achieve the purpose of saving energy and reducing consumption, but there is still the problem of dust accumulation and pipe blockage in the pipeline due to the closure or adjustment of the dust collection branch pipe
