Multi-fan central dust-removing device and dust-removing method

Abstract

The invention provides a multi-fan central dust-removing device comprising dust remover air inlets, a dust collection system, a filtering system, an ash cleaning system, a fan system, a pressure sensor and a control system, wherein the dust collection system is connected with the dust remover air inlets through a pipeline; the filtering system is connected with the dust collection system and comprises filtering cylinders; the ash cleaning system is used for cleaning dust accumulated on the filtering cylinders and is arranged above the filtering cylinders; an inlet of the fan system is connected to an outlet of the filtering system and the fan system comprises a plurality of small-sized fans; the pressure sensor is used for detecting air quantity of the dust remover air inlets and outputting a pressure induction signal; and the control system comprises an intelligent energy-saving system for controlling the quantity of the started and stopped fans according to the actually-used air quantity, and an ash cleaning control system for carrying out ash cleaning on the filtering cylinders of the filtering system at regular time. The multi-fan central dust-removing device disclosed by the invention has the advantages of small volume, low noises, high dust-removing efficiency, obvious energy-saving effect and stable operation.

Description

Technical field [0001] The invention relates to the field of dust removal, in particular to a central dust removal device and a dust removal method. Background technique [0002] Domestic dust removal devices of the same kind are generally equipped with 1-2 large fans, which generally use fan frequency conversion to save energy, and the range of energy saving is limited, between 10%-20%. Because the air volume of the fan, the wind pressure power will change with the current frequency However, the vacuum port of the processing equipment that needs to be vacuumed must ensure a certain pressure, so the frequency of adjustment cannot be very large; and if a large fan fails, the entire dust removal system will be paralyzed, and the operational stability cannot be guaranteed. Summary of the invention [0003] In order to solve the above problems, the present invention proposes a multi-fan central dust removal device, which is small in size, low in noise, high in dust removal efficiency,...
