[Industrial application field]

The present invention relates to a dust collection and processing device.

0002

[Conventional technology]

During engine operation tests, the exhaust gas emitted from the engine contains soot and dust such as black smoke. Because it contains soot and dust, it is necessary to remove the soot and dust in order to release the exhaust gas into the atmosphere. For this reason, dust collection equipment has been used for a long time.

0003 An example of such a dust collection processing device is shown in Figs. 2 and 3, in which 1 indicates the dust collector main body. It is the body. A collection container 2 is connected to the lower part of the dust collector body 1 via a damper 20. In addition, the dust hopper chamber 3 has a rectifying plate 19 in the middle, and the upper part of the dust hopper chamber 3 are installed through the partition wall 4, and are formed in multiple rows with the partition wall 21 in between, as shown in FIG. Each bag filter chamber 5 is provided with a bag filter chamber 5 with A plurality of bag filters 6 which are installed and open toward the dust hopper chamber 3 are housed. The dust hopper chamber 3 and each bag filter chamber 5 are separated by a partition wall 4 and a bag filter. It is partitioned by 6.

0004 7 is a collecting duct connected to the dust hopper chamber 3 of the dust collector main body 1; The duct 7 includes a plurality of pipes for introducing exhaust gas 9 from the engine into the collecting duct 7. Several exhaust gas introduction ducts 8 are connected.

[0005] 10 is a manifold connected to an exhaust nozzle 22 protruding from each bag filter chamber 5. 11 is a damper housed in each exhaust nozzle 22 so as to be openable and closable. , 12 is an exhaust duct for transporting clean gas 13 from which soot and dust 15 have been removed from each bag filter chamber 5. Connected to the tip of the exhaust duct 10 for discharging from the exhaust tower 14 into the atmosphere via the exhaust duct 10. The exhaust blower 16 is an outside air introduction duct connected to each bag filter chamber 5. 7 is a damper housed in each outside air introduction duct 16 so as to be openable and closable, and 18 is an outside air introduction duct. This is a ventilator provided at the upper end of the vent 16.

[0006] Exhaust gas 9 from the engine passes through an exhaust gas introduction duct 8 and a collection duct 7 to a dust collector. The dust is guided to the dust hopper chamber 3 provided in the main body 1, and in the dust hopper chamber 3, The air is rectified by the rectifying plate 19 and then sent to the bag filters 6 each opened in the dust hopper chamber 3. will be introduced.

[0007] The soot and dust 15 in the exhaust gas 9 is removed from each bag filter when the exhaust gas 9 passes through the bag filter 6. Clean air is collected and purified by the bag filter 6 when exhausted into the filter chamber 5. The clean gas 13 flows through the exhaust duct 10 from the exhaust nozzle 22 with the damper 11 open. is induced by the exhaust blower 12 through the exhaust tower 14 and discharged into the atmosphere. .

[0008] As mentioned above, when collecting the soot and dust 15 in the exhaust gas 9 with the bag filter 6, each The damper 17 is in a closed state, and the inside of each bag filter chamber 5 is filled by the attractive force of the exhaust blower 12. There is a negative pressure, and the soot and dust 15 removed from the exhaust gas 9 is transferred to the bag filter 6. It adheres to the inner surface as soot and dust 15a.

[0009] When the amount of dust 15a attached to the bag filter 6 reaches a certain level, it is collected. To ensure good operation of the dust machine body 1, dust 15a is brushed off from the bag filter 6. Therefore, the following operations are performed.

0010 That is, a bag filter including a bag filter 6 that attempts to blow off soot and dust 15a. The damper 11 of the exhaust nozzle 22 provided in the chamber 5 is closed, and the outside air introduction da When the damper 17 of the vent 16 is opened, the other bag filter chambers 5 are closed to the exhaust valve. The pressure is negative due to the attraction of the lower 12, and the dust hopper chamber 3 is also negative pressure. Therefore, the outside air passes through the ventilator 18 and the outside air introduction duct 16, and enters the dan. It flows into the bag filter chamber 5 with the damper 11 closed and the damper 17 opened. 5, flows into the dust hopper chamber 3 through the bag filter 6, and enters the bag filter 6. The attached soot dust 15a is brushed off and falls into the dust hopper chamber 3 (15 ).

[0011] When a certain amount of soot 15 has accumulated in the dust hopper chamber 3, open the damper 20 and collect it. The soot and dust 15 is dropped into the container 2, and the collection container 2 containing the soot and dust 15 is taken over by a trader. I was trying to let them handle it.

0012

[Problem that the idea aims to solve]

However, the particle size of soot dust 15 is very small, about 0.1μ or less, so , many of them pass through the bag filter 6, making it difficult to collect them, and As mentioned above, the collected soot and dust 15a without passing through the bag filter 6 is sent to the dust hopper. If the soot and dust 15 is dropped directly from the chamber 3 into the collection container 2 for treatment, the volume of soot and dust 15 will be reduced. Because they are large and floating, they easily stain clothes and the area around the dust collection equipment. Collection and processing work was difficult and the costs involved were also high.

[0013] In view of such circumstances, the present invention can increase the particle size of soot dust to ensure collection, In addition, the volume of soot and dust can be reduced, reducing the amount of dirt on clothes and around the equipment, making the recovery process easier. The purpose of the present invention is to provide a dust collection and processing device that can facilitate the work.

[0014]

[Means to solve the problem]

This invention is a dust hopper where exhaust gas from the engine is introduced through a collection duct. It has a dust hopper chamber and a bag filter chamber, and the bag filter chamber has a direction toward the dust hopper chamber. A bag filter is installed that opens at the bottom and separates the bag filter room and dust hopper room. dust collector body, an exhaust duct connected to the bag filter chamber of the dust collector main body; an exhaust blower that discharges exhaust gas from the bag filter chamber to the outside through an exhaust duct; and, an electric condenser installed in the middle of the collecting duct; A solidification device for soot and dust installed at the bottom of the dust hopper chamber via a damper. and, a collection container attached to the bottom of the solidification device via a damper; It is characterized by having the following.

[0015]

[Effect]

Therefore, when the exhaust gas from the engine passes through the electric condenser in the middle of the collection duct, Fine soot and dust in the exhaust gas is affected by the corona discharge action inside the electric coagulator, which is applied with high voltage. As a result, the exhaust gas from the dust hopper chamber passes through the bag filter and the bag filter becomes swollen. The bag filter ensures that the soot and dust is collected and removed when it is exhausted into the router room. The clean gas is drawn from the exhaust duct by the exhaust blower and discharged into the atmosphere. It will be done.

[0016] On the other hand, due to backwashing of bag filters in each bag filter room, which is carried out regularly, When a predetermined amount of soot and dust accumulates in the dust hopper chamber, the damper opens and the dust hopper chamber opens. When the soot and dust falls into the solidification device and is solidified in the solidification device, The damper opens and solid soot falls into the collection container.

[0017]
