Description
Technical Field
The invention relates to the technical field of environmental treatment and dust removal, in particular to an ash-free negative ion bag type smoke purification device.
Background
The bag type dust collector is a dry dust filtering device. The filter bag is made of woven filter cloth or non-woven felt, dust-containing gas is filtered by utilizing the filtering effect of fiber fabric, and when the dust-containing gas enters the bag type dust collector, dust with large particles and large specific gravity falls down due to the effect of gravity and falls into the ash bucket, and when the gas containing finer dust passes through the filter material, the dust is blocked, so that the gas is purified. Are often used in dust removal facilities in large industrial fields.
After the filter material of the bag type dust collector is used for a period of time, a layer of dust is accumulated on the surface of the filter bag due to the effects of screening, collision, retention, diffusion, static electricity and the like, the layer of dust is called a primary layer, the primary layer becomes a main filter layer of the filter material in the following movement process, and the filter material with larger meshes can also obtain higher filter efficiency by virtue of the action of the primary layer. 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 on two sides of the filter material is large, some fine dust particles attached to the filter material are extruded to pass, so that the efficiency of the dust remover is reduced. In addition, the air quantity of the dust removing system is obviously reduced due to the excessively high resistance of the dust remover. Therefore, after the resistance of the dust remover reaches a certain value, the dust needs to be removed in time. The primary layer cannot be destroyed during ash removal so as to avoid efficiency reduction.
The negative ion generator is a device for generating air negative ions, and the negative ion generator increases negative ion components in the air by utilizing high-voltage corona, so that the air quality is improved, the health of the human body can be promoted, and the human body is known as air vitamin. Are commonly used in living or small purified air environments. At present, the negative ion generator is applied to a dust removing device, and mainly generates charged negative ions to adsorb dust particles so as to charge the dust particles, thereby agglomerating and settling. However, the current negative ion electric field part structure is easy to generate short circuit phenomena such as arc discharge, wire bonding and the like, so that the negative electrode is difficult to stably maintain negative high potential, the ionization efficiency is reduced, the number of free electrons is reduced, and the purification effect is further influenced.
