Description

Pre-processing dust removal filter device for electric precipitator with automatic washing function {AUTOMATICALLY WASHABLE PRE-PROCESSING DUST FILTER DEVICE OF ELECTRICAL DUST COLLECTOR}

The present invention relates to a dust removal filter as a pretreatment device for an electric collector that treats white smoke discharged from processes such as a tenter process of a textile dyeing factory, and a pretreatment device for lint and fine dust generated in a large amount during a fiber tenter process. Specifically, in installing an electric dust collector to treat white smoke discharged during the fiber tenter process, a large amount of yarn and fine dust (dust) is discharged, increasing the pollution of the electric dust collector, and thus the electric dust collector dust collecting filter (cell In order to solve the difficulty of management due to frequent cleaning of ), it relates to a pre-treatment filter that is installed at the inlet of the electric dust collector to primarily filter thread lint, dust, and fine dust.In particular, the pre-treatment filter is cleaned automatically. Thus, it is possible to increase the cleaning cycle by minimizing clogging of the dust collecting filter (cell) of the electric precipitator due to dust, and to a pretreatment filter with greatly improved maintenance.

The problem of discharging large amounts of high-temperature white smoke and fine dust in the process of ironing (tentering) fibers is a very serious environmental problem and is a problem to be solved nationally. Pollutants discharged from textile factories are high-temperature volatile substances. Consisting of oil and moisture, and a large amount of fluff and dust, there are complex treatment problems. To solve this problem, several technologies must be combined in a complex manner. The present invention uses a dry electrostatic precipitating technology using micropulse charging used in the process of treating white smoke, and by rapidly ionizing and collecting pollutants discharged by plasma discharge by micropulse charging, the pollutants and air are separated. When it comes to recovery, dust is collected and clean air is discharged to the outside.

In the use of such a dry electric dust collector, the tenter process of the fiber has a discharge temperature of 130 degrees or higher, and a large amount of lint and dust are introduced into the electric dust collector, and the dust collecting cell of the electric dust collector is maintained due to the inflow of a large amount of dust. A problem that becomes very difficult for users occurs, which makes it difficult for users to manage. In order to solve this problem, a separate pretreatment filter may be installed at the inlet of the electric precipitator, and the air introduced into the precipitator may be primarily filtered.

Such a filter may be configured by installing a plate type filter such as, for example, Korean Patent Publication No. 2016-0143488, at an inlet portion of an electric dust collecting device such as Korean Patent Publication No. 2015-0058728. The filter installation structure of this inlet can be implemented in particularly dusty sites as described above.

In the case of such an existing filter structure, when it is used in a dusty field, if oil deposits and dust accumulate in the dust collection filter, static pressure loss occurs due to clogging of the filter, causing frequent cleaning or filter replacement. do. In other words, in this case, the dust collector is stopped and the operator directly separates the filter, washed and dried, and then used again.

Accordingly, the present invention is devised to solve the problems of the above-described existing technologies, and provides a filter having a function of removing dust and thread that can be cleaned automatically in the primary filter structure installed in the inlet of the dust collector. It is possible to minimize clogging while removing dust or dust caused by the door, and at the same time, it automatically cleans without opening and closing the door to minimize the time required for cleaning to prevent static pressure loss, while the dust collector stops for cleaning according to the purpose of installation. It is an object to provide a technology that can greatly increase the purpose of use by allowing it to continue to operate without causing it to have the efficiency of reducing air pollution as it is.

In addition, the present invention proposes a new structure in which the filter is cleaned automatically, but the filter is easily separated and washed, greatly increasing the efficiency of the separation and washing in addition to the above-described cleaning efficiency, thereby increasing the operation efficiency of the dust collector. It has a different purpose to provide technology that can be greatly increased.

Preferably, the main frame includes a clip-shaped coupling part installed on the open line to control separation when the filter part is installed.

According to the present invention, when the washing liquid supply means operates according to a control command of the processor to the washing liquid supply means, the washing liquid supply means evenly sprays the washing liquid to the entire filter unit. Accordingly, it is possible to automatically wash the filter.

By performing this function, it is possible to evenly and automatically clean the filter without separate separation of the filter, thus minimizing clogging during dust removal by the filter and minimizing the time required for cleaning to prevent static pressure loss. There is an effect of greatly increasing the operation efficiency of the dust collector by ensuring the maximum operation time of the dust collector.

On the other hand, even when washing by separating the filter is necessary, it can be easily installed and separated by a sliding method, so the time and human resources required for washing the filter are minimized, and the operation efficiency of the dust collector is greatly increased as the washing efficiency increases. There is an effect that can be made.
