BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an industrial storage space and a heating apparatus for a dust collector hopper, and more particularly to a heating and maintaining apparatus for a hopper located in a lower portion of a dust collector.

Dust collectors are used to collect dust discharged from a dust generating process such as general coal or heavy oil combustion process, waste incinerator process, cement manufacturing industry, and steelmaking process, clean it with clean air, and discharge it to the outside.

The dust collector filters the polluted air to filter the dust, and discharges clean air to the outside. The upper spray nozzle injects the compressed gas into the bag filter to desorb dust collected in the bag filter, Prevents clogging of filter and improves purification efficiency.

A hopper is installed at the lower part of the bag filter to store the removed dust for a predetermined period of time and is discharged to the outside by a discharge device at the lower part thereof.

Conventionally, when humidity or condensation occurs due to the temperature difference between the inside and the outside of the hopper, low-temperature corrosion occurs in the hopper steel plate, and the dust is condensed and can not be smoothly discharged to the bottom.

Accordingly, in order to remove moisture or prevent condensation, conventionally, an electric hot wire or a hot steam pipe was wound around the hopper to keep the temperature constant, and the outside of the hopper was wrapped with a heat insulating material and kept warm.

The dust is dropped to the bottom by using the vibration of the motor or periodically applying an impact using an air knocker to prevent dust from accumulating inside the hopper.

However, in the past, such an impact causes a short circuit of the electric hot wire or breakdown of the hot steam pipe.

When such a failure occurs, it is conventionally necessary to tear off all of the heat insulating material and short-circuit the electric hot wire or to locate and repair the rupture part of the steam pipe, and it takes a lot of time and requires a lot of replacement cost.
