Technical Field
The invention relates to the technical field of dust removal control, in particular to an intelligent dust discharging control method of a bag type dust collector.
Background
The bag type dust collector is a dry dust filtering device for collecting solid particles in dust-containing gas by utilizing a bag-shaped filter element made of fiber fabrics, is suitable for collecting fine, dry and non-fibrous dust, and consists of an upper box body, a middle box body, a lower box body, a dust cleaning system, a dust discharging system and other structures, and the working principle is as follows: when the dust-containing gas passes through the filtering layer, dust particles in the gas flow are intercepted and trapped by the filtering layer, so that gas-solid separation is realized. After the filter material is used for a period of time, due to the effects of screening, collision, detention, diffusion, static electricity and the like, a layer of dust is accumulated on the surface of the filter bag, the layer of dust is called as a primary layer, in the later movement process, the primary layer becomes a main filter layer of the filter material, and the filter material with larger meshes can obtain higher filtering efficiency by virtue of the action of the primary layer. Along with the accumulation of dust on the surface of the filter material, the efficiency and the resistance of the dust remover are correspondingly increased, and when the pressure difference between two sides of the filter material is large, some fine dust particles attached to the filter material are extruded, so that the efficiency of the dust remover is reduced. In addition, the air volume of the dust removal system is significantly reduced due to the excessively high resistance of the dust remover. Therefore, the dust is removed in time after the resistance of the dust remover reaches a certain value. The initial layer cannot be damaged during ash removal, so that the efficiency is prevented from being reduced.
Present bag collector is comparatively extensive in the factory building application, the bag collector of quantity can reach the operation requirement about two in some small-size processing factory buildings, and to some large-scale processing factory buildings, then need install a large amount of bag collectors, the quality of control in whole large-scale factory buildings is ensured, and to a plurality of dust remover during operation, current control system exists that control is not comprehensive, the condition of easily causing the electric energy waste takes place, can not realize through setting up dust concentration check out test set at each dust remover position, come to cooperate each dust remover to detect the dust removal, unable reach the purpose of carrying out independent control dust removal separately with each dust remover, can not realize simultaneously carrying out the independent dust removal control to every dust remover, can not reach the purpose that not only quick but also the efficient unloaded the ash to the dust remover and handle, thereby bring very big inconvenience for people's use.
