Problems solved by technology

However, this dust collector cannot be used for industrial dust removal due to its obvious shortcomings: First, the dust removal module cannot be regenerated. When the channel of the module is blocked and saturated by dust, it can only be regenerated by pulling the brush out of the channel and fully cleaning it. , another regeneration method is to immerse the module in water, and complete the regeneration through water washing and ultrasonic vibration
When the module size is small, the above two regeneration methods are feasible, but for the large size module used for industrial dust removal, these regeneration methods are no longer applicable
Second, the honeycomb carrier disclosed in the technical document ZL201210418554.4 is a porous honeycomb ceramic, but when the module size is large (for example, the aperture is 10cm), this honeycomb ceramic will be difficult to process, and the self-weight of the ceramic is too large
For the above two reasons, the technical solution disclosed in ZL201210418554.4 cannot be applied in the field of industrial tail gas dust removal
[0006] Since the honeycomb channel carrier and the twisted wire brush can be combined into a high-efficiency and low-resistance dust removal module, can the innovative design of the module give the module easy regeneration performance and apply it to industrial dust removal? The present invention aims to solve the above problems, while taking advantage of the high-efficiency dust removal effect and low air resistance advantages of the honeycomb channel carrier and the twisted wire brush, it solves the problem that it is difficult to regenerate, thereby obtaining an industrial dust removal device that can be continuously operated

Embodiment 1

[0021] Put 4 twisted wire brushes into the carrier with 4 parallel channels respectively, the twisted wire brush bristles are divided into two sections, the width of the bristle position is the same as the length of the channel of the carrier, which is 100mm, and the twisted wire brush has The diameter of the brush body is 1.0 times the long diameter of the channel section of the carrier, the channel of the carrier is a square hole with a width of 10 mm, the material of the carrier is cordierite, and the two ends of the twisted wire brush are respectively fixed on two positioning frames, The entire twisted wire brush group is formed into a twisted wire brush group with a fixed frame, and guide rods are respectively installed on the outside of the two positioning frames, which are used to drag and move the twisted wire brush group. A downward compressed air blowing port is set up for blowing and dedusting regeneration of the twisted wire brush group dragged out of the carrier, a...

Embodiment 2

[0023] Insert 9 brush rollers into the carrier with 9 parallel channels respectively. The bristles of the brush rollers are divided into three sections. It is 1.3 times of the major diameter of the carrier channel section, the channel diameter of the carrier is a hexagonal hole with a circumscribed circle diameter of 300mm, the material of the carrier is stainless steel, and the carrier of the stainless steel material is welded to the stainless steel flower plate at both ends of 9 stainless steel tubes and The outer shell is welded with a hollow closed structure. The two ends of the brush roller are respectively fixed on two positioning frames, so that the entire brush roller is composed of a brush roller group with a fixed frame. The outer parts of the two positioning frames are installed with guides The rod is used to drag and move the brush roller set, and downward compressed air blowing ports are arranged at both ends of the carrier, which are used to spray and remove dust ...

Embodiment 3

[0025] Insert 16 twisted wire brushes into the carrier with 16 parallel channels respectively. The bristles of the twisted wire brushes have two sections. The diameter of the brush body is 1.1 times the long diameter of the channel section of the carrier. The channel of the carrier is a round hole with a diameter of 100mm. The material of the carrier is aluminum alloy. The hollow closed structure of the board and the outer shell is welded. The two ends of the twisted wire brush are respectively fixed on the two positioning frames, so that the entire twisted wire brush group becomes a twisted wire brush group with a fixed frame. The outer parts of the two positioning frames Guide rods are respectively installed to drag and move the twisted wire brush group, and downward compressed air blowing ports are set at both ends of the carrier to carry out the twisted wire brush group dragged out of the carrier. Injection dust removal and regeneration, two ash hoppers are respectively ar...

Abstract

The invention relates to a continuous industrial dust collector, and belongs to the technical fields of exhaust gas treatment, dedusting and environment protection. A technical scheme is characterized in that a twisted hairbrush or a hairbrush roller is provided with segmented brush hair and moves through the dragging effect of a guide rod and a locating frame, the brush hair and tunnels of a porous carrier form a dedusting tunnel when the tunnels of the porous carrier on an exhaust gas pipeline are filled with the brush hair to collect dust-containing gas, when the dusts in one segment of brush hair are saturated, the dust-containing brush hair is removed from the tunnels of the porous carrier through the dragging of the guide rod, another segment of cleaning brush hair is inserted into the tunnels of the porous carrier to carry out new round dedusting, and the dust-containing brushing hair removed from the tunnels of the porous carrier is regenerated by using blowing of compressed air. The characteristics of high efficiency and small pressure drop of a twisted brush and porous carrier composite dedusting module are performed, and the disadvantage of difficult regeneration of an original module is overcome.

Description

technical field [0001] The invention relates to a continuously operating industrial dust removal device, which belongs to the technical fields of waste gas treatment, dust removal and environmental protection. Background technique [0002] With the rapid development of my country's economy, the haze air pollution in large and medium-sized cities, economically developed areas and areas with intensive basic industries in my country is becoming more and more serious. As my country's restrictions on SOx and NOx emissions become increasingly stringent, and related environmental protection technologies and devices continue to be put into use, the total emissions of SOx and NOx pollutants in my country's atmospheric environment have decreased year by year. However, from the current monitoring results, my country's Yangtze River Delta On the contrary, the smog pollution in the Pearl River Delta and Beijing-Tianjin-Hebei areas is becoming more and more serious, which has seriously thr...
