Description

TECHNICAL FIELD

[0002] The bag-type dust filtration and removal device is widely used in various fields such as metallurgy, chemical industry and manufacturing industry due to its high filtration efficiency of pollution particulate matters. Since the tail gas of the metallurgical and chemical industries is often high-temperature, and some spark high-temperature particulate matters may be mixed in the emission due to process defects or operation reasons, the spark high-temperature particulate matters are easily and quickly introduced into the bag-type dust collector at the tail end of the dedusting pipeline due to the high flow speed of 20 m / s of the smoke dust in the pipeline at the front end of the bag-type dust collector, which ignites the combustible dust accumulated on the surface of the filter bag and causes deflagration, thereby causing a huge safety accident. At present, the far-infrared detector is mainly used to monitor the high-temperature spark particulate in the dedusting pipeline, and the detection head thereof is arranged at the opening position of the inner wall of the pipeline and is used to monitor the high-temperature spark in the pipeline so as to provide a judgment basis for the fire-fighting facilities downstream of the pipeline.

[0003] Since the high-temperature smoke dust particulate is quickly flowing in the pipeline, the spark detector probe is quickly attached and contaminated by the smoke dust particulate, which causes the infrared detector to be blind and lose the detection function, and the detector probe needs to be frequently disassembled and manually cleaned. Meanwhile, the internal temperature of the dedusting pipeline of the metallurgical industry is as high as about 350 DEG C, and the flow speed is 15-25 m / s, and the conventional cleaning method cannot realize the timely cleaning of the probe glass of the inner wall of the pipeline.

It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0026] As shown in Figures 1 to 9 the bag-type dust collector high-temperature dust removal pipeline detector observation window glass self-cleaning device of the present embodiment is composed of a high-temperature dust removal pipeline 1, a bucket-shaped front chamber 2, a machine box bin 3, a glass cleaning agent bin 4, a connecting piece 5, a cover 6, a cleaning agent filling pipe 7, a glass carrier tray 8, a cleaning agent pipeline 9, optical glass 10, a spark detection device main machine 11, a stepping motor 12, a fixed support 13, a water pump 14, a liquid collection drainage pipe 15, a waste liquid emptying valve 16, a machine box door 17, a first heat insulation rubber ring 18, an observation port 19, a second heat insulation rubber ring 20, a first through hole 21, an air inlet slit 22, a main cleaning rubber strip 23, a pre-cleaning rubber strip 24, a third heat insulation rubber ring 25, a liquid collection rubber strip 26, an atomizing nozzle 27, and a second through hole 28.

[0031] The working principle of the embodiment is as follows: the spark detection device host 11 sends an action signal to the stepping motor 12 according to a preset time period, the stepping motor 12 rotates by a preset fixed angle, the output shaft of the stepping motor 12 drives the clean optical glass 10 on the glass carrier 8 to rotate, the clean optical glass 10 rotates to the observation port position of the spark detection device host 11, at the same time, the clean optical glass 10 is located at the position in front of the observation port 19 of the machine box compartment 3, the first through hole 21 of the hopper-shaped front chamber 2 and the second through hole 28 of the high-temperature dust removal pipeline 1, and the contaminated optical glass 10 is rotated into the cleaning area. In the rotating process of the optical glass 10 on the glass carrier 8, the surface floating dust of the optical glass 10 is removed by the pre-cleaning rubber strip 24, the water pump 14 pumps the cleaning agent in the glass cleaning agent compartment 4 into the cleaning agent pipeline 9, the cleaning agent in the cleaning agent pipeline 9 sprays the glass cleaning agent to the optical glass 10 in the cleaning area through the atomizing nozzle 27, and the soot particles on the contaminated optical glass 10 are washed, the cleaned optical glass 10 passes through the main cleaning rubber strip 23 to scrape the sewage left on the optical glass 10, so as to ensure the cleanliness of the surface of the optical glass 10 after rotating out of the cleaning area, and the sewage generated in the cleaning process flows downward along the liquid collecting rubber strip 26 to the liquid collecting drainage pipe 15 through the gap between the inner wall of the machine box compartment 3 and the glass carrier 8, and then flows into the glass cleaning agent compartment 4 at the bottom of the machine box compartment 3. The cleaning agent in the glass cleaning agent compartment 4 can be periodically emptied and replaced according to the actual working condition, so as to ensure the cleaning effect of the glass.
