To solve this problem, a dust collector for removing fine particles through a filter has been developed.

The dust collector is classified into various types such as mechanical, electric, dry, and wet type according to the operation principle. Recently, the dust collector is classified into various types such as various heating furnaces and the like through the specific places such as the charging port and the combustion gas discharging port, BACKGROUND OF THE INVENTION [0002] A bag filter, which is a large-capacity dust collecting device suitable for a facility in which particles are concentrated in large quantities, has appeared and is widely used.

However, mobile dust collectors have been developed to remove dust generated during blasting work or tunnel repair work in tunnels.

For example, Korean Utility Model Registration No. 20-188810 discloses a dust collecting hood unit installed horizontally and vertically movably on a movement path of a raw material input tripper, A weight detector for sensing the weight of the foreign matter on the lower surface of the screen mat by the load cell, a foreign matter removing unit for removing the foreign matter on the screen mat, And a dust storage tank for storing dust after being collected by a dust collecting hood.

Practical phosphate registration No. 20-352595 and Korean Patent Laid-Open Publication No. 10-2004-31720 disclose a suction type The dust suction inlet provided with the fan is connected to the upper side surface of the first filter by the first flue, so that the collected air is supplied to the first filter while causing the swirling air flow, and the air in the air supplied to the first filter The dust is collected by dust collecting water sprayed to the spraying nozzle by the jet pump and collected in the collecting tank through the powder outlet, and at the same time, And a second filter connected to a lower side of the second filter to generate a swirling air flow, the remaining air being supplied to the second filter is supplied to the second filter through the injection nozzle, And the dust-removed air is exhausted through the outlet of the dust collector, and the fine dust is removed from the third filter including the demister filter. Thereafter, the clean air There is disclosed a technique relating to a water jet type cyclone dust collector applying centrifugal force to discharge purified air through an exhaust doctor provided with an exhaust fan after fine dust is removed from a third filter including an exhaust doctor demister filter provided with an exhaust fan have.

In the Utility Model Registration No. 20-281132, a suction plate capable of sucking air is formed at one side of a tube connected to the main body, a catching net for filtering a plurality of purger n fans and dusts at predetermined positions in the main body, A smoke inhalation device capable of assembling a filter to purify the smell of food generated in a cigarette smoke and kitchen has been disclosed. In Publication No. 20-185328, a secondary purifier And a motor having a suction fan therein is installed together with a suction tube disposed above the purifying filter, and a dust discharging cylinder having a large mesh is provided above the suction tube to collect the dust, If the suction motor is operated by operating the internal motor of the dust collecting apparatus, it is blown out from the room when the suction fan is operated. Discharge trough has a removable dust collecting device is disclosed consisting of.

However, the above-described conventional techniques have been disadvantageous in that dust can not be removed in large quantities during various constructions of tunnels and thus can not be practically used.

In addition, since the conventional mobile air purification apparatus is driven by an electric motor, there is a limitation in mobility and maneuverability. Accordingly, in the present invention, the engine and the air purification apparatus are integrally mounted on the vehicle, Thereby facilitating efficient management and operation.

The dust collector collects the air discharged from the inside of the tunnel, removes dust mixed in the air, and then discharges the clean air from which dust has been removed to the atmosphere.

In the meantime, dust and gas removal inside the tunnel using the conventional blower and dust collector as described above is not limited to the use of the power supply since the cable connection line is short during the initial implementation of the tunnel construction site. However, The cable must be lengthened causing problems with the power supply.

That is, in the past, it was operated as a temporary power source in the field, and as the tunnel excavation progressed, the primary power was continuously extended to supply power. However, in the case of the heavy and large tunnels, materials and labor costs for additional power lines were added. The cable must be wound around the cable wheel again by separating the wires from the cable.
