Description

Technical Field

[0001] The invention relates to a device for removing dust discharged from a melting furnace. Background Art

[0002] Exhaust gas generated by conventional waste (solid and liquid) incinerators and / or melting furnaces during incineration and melting (vitrification) of hazardous waste contains solid phase particles such as unburned carbon, ash, and heavy metal particles, as well as liquid phase particles.

[0003] In order to handle these fine particles (dust), it is first necessary to separate them from the gas phase substances in the exhaust gas to collect dust. The dust (ash and fly ash) generated at this time is secondary waste and needs to be treated separately. In particular, when handling radioactive waste, the dust generated has radioactivity, so special attention must be paid when handling it.

[0004] In addition, dust generated when solid waste is introduced and a large amount of water generated when liquid waste is introduced may cause dust to accumulate inside the pipe cooler.

[0005] This dust accumulation phenomenon not only makes it difficult to handle the dust due to its scattering nature, increases the cost of dust treatment and complicates the related equipment, but also ultimately reduces the utilization rate of the melting furnace. Summary of the invention

[0010] The exhaust portion may include: an exhaust port connected to the melting space; a first pipe connected to the exhaust port along a first direction; a second pipe connected to the first pipe in a bent manner; a connecting portion for connecting the first pipe and the second pipe; and a moisture cooler for cooling the moisture discharged through the second pipe.

[0011] The exhaust unit may further include: a pressure measuring instrument for measuring the internal pressure of each of the first pipe and the second pipe; and a stopper for preventing the filter from being detached, wherein the first direction is a vertical direction and the second pipe extends in a horizontal direction.

In addition, in the accompanying drawings, in order to illustrate the relationship between the various components, the size and spacing may be exaggerated in a manner different from the actual one.

[0031] Reference Figures 1 to 4 , a device for removing dust discharged from a melting furnace (hereinafter referred to as a "dust removing device") according to a first embodiment of the present invention is described.

[0032] Figure 1 The melting device of the first embodiment of the present invention is shown. Figure 2 The enlarged view shows Figure 1 A in Figure 3a and Figure 3b A filter of a melting device according to a first embodiment of the present invention is shown. Figure 4 A driving unit according to a first embodiment of the present invention is shown.

[0033] The dust removal device 1 includes an exhaust unit 100 , a filter 200 , and a dust removal unit 300 .

[0034] The exhaust part 100 is used to discharge dust and moisture discharged from the melting space T of the melting furnace, and includes an exhaust port 110 , a first pipe 120 , a second pipe 130 , a connecting part 140 , a moisture cooler 150 , a pressure measuring instrument 160 , and a stopper 170 .

[0035] The exhaust port 110 is communicated with the melting space T, and is a hole for discharging dust and moisture generated in the melting space T to the outside. In the present invention, the exhaust port 110 is shown to be disposed at the upper end of the melting furnace, but is not limited thereto.

[0036] The first duct 120 is connected to the exhaust port 110 along a first direction, and the volume and length of the duct can be adjusted to enable dust and moisture exhausted from the exhaust port 110 to move slowly through the first duct 120 .

[0037] The first direction is a vertical direction, and the vertical direction may be 80 to 105 degrees, 85 to 100 degrees, 85 to 95 degrees, and preferably 87.5 to 92.5 degrees.

[0038] The second pipe 130 is connected to the first pipe 120 in a bent manner. In the present invention, it is shown that the moisture cooler 150 wraps the second pipe 130 to cool the moisture passing through the second pipe 130, but it is not limited thereto.

[0039] The horizontal position may be 0 to 15 degrees and 0 to 10 degrees, preferably 0 to 5 degrees.

[0040] The connecting portion 140 is used to connect the first pipe 120 and the second pipe 130. In the present invention, the first pipe 120 and the second pipe 130 are connected by bending. The connecting parts 140 of the glyphs are connected to each other, but are not limited thereto.

[0041] The moisture cooler 150 has a larger diameter than the second pipe 130 and wraps the second pipe 130 with a maximum area, so that the cooling efficiency of cooling the moisture discharged through the second pipe 130 can be maximized.

[0042] The pressure measuring instrument 160 is used to measure the internal pressure of the first pipe 120 and the second pipe 130. In the present invention, the pressure measuring instrument 160 simultaneously measures the pressure of the first pipe 120 and the second pipe 130. Although not shown, a monitoring device and a communication device for confirming the pressure change in real time may be further provided.

[0043] The stopper 170 is arranged (attached) on the inner wall surface of the connection part 140 to prevent the filter 200 from being separated. In the present invention, two stoppers 170 are arranged (attached) along the horizontal direction of the second pipe 130 to prevent the filter 200 from moving, but it is not limited thereto. In another embodiment, the number and shape of the stoppers 170 can be changed according to the shape of the connection part 140 and the setting position of the filter 200.

[0044] The filter 200 is located inside the exhaust part 100 and is configured such that one surface thereof faces the melting space. The filter 200 is plate-shaped and is disposed in the connection part 140 between the first pipe 120 and the second pipe 130 along an oblique direction.

[0045] Reference Figure 3a and Figure 3bIn the present invention, the filter 200 is shown to use a mesh type (a) or a perforated type (b), but is not limited thereto. Although not shown, a supporting unit for fixing the filter 200 may be further provided in the connection portion 140 .

[0046] The dust removal unit 300 is used to improve the dust removal capability of the filter 200 or to improve the performance of the filter 200 , and includes a driving unit 310 and a driving control unit 320 .

[0047] The dust remover 300 improves the dust removal capability of the filter 200 or improves the performance of the filter 200 by applying physical force to the filter 200 through the driving of the dust remover 300 so that the filter 200 can remove dust accumulated in the exhaust unit 100 in greater quantity or more easily.

[0048] In addition, improving the dust removal capability (dust removal capability) means maximizing the dust removal effect of the filter 200, that is, maintaining the filter 200 itself at a predetermined performance so as to remove dust in the filter 200 to a predetermined degree.

[0049] The easier it is for dust to fall off the filter 200 , the more the dust removal unit 300 can improve the dust removal capability of the filter 200 or the performance of the filter 200 .

[0050] The driving units 310 , 310 ′, 310 ″, and 310 ′″ are used to apply physical force to the filter 200 to make the dust accumulated on the filter 200 fall off.

[0051] The drive control unit 320 controls the driving of the drive units 310, 310', 310", 310'" based on the measured value of the pressure measuring instrument 160, and only when the pressure difference between the first duct 120 and the second duct 130 is greater than a specified value, the dust accumulated on the filter 200 is removed.

[0052] The dust remover 300 specifically removes the dust in the following manner: First, the internal pressures of the first duct 120 and the second duct 130 are checked by the pressure measuring instrument 160 to measure the pressure change before and after the filter 200 .

[0053] When a large amount of dust accumulates on the filter 200, the pressure increases. At this time, the drive control unit 320 drives the drive unit 310, thereby applying physical force to the filter 200, so that the dust accumulated on the filter 200 falls off. Thereafter, the fallen dust returns to the melting space T.

[0054] The driving unit 310 (Embodiment 1) is driven according to the control of the driving control unit 320, and although not shown, may further include a supporting unit for fixing the driving unit 310 to the exhaust unit 100. In addition, a power supply device for supplying power to the driving unit 310 may be further included.

[0055] Reference Figure 4 A portion of the driving unit 310 of the first embodiment of the present invention is combined with the filter 200, and a portion of the filter 200 is moved up and down by the driving of the driving unit 310. The accumulated dust falls off by the up and down movement of the filter 200, and the fallen dust returns to the melting space T due to its own weight.

[0056] Reference Figures 5 to 9 The driving units according to the second to fourth embodiments of the present invention are described.

[0057] Figure 5 shows a driving unit according to a second embodiment of the present invention, Figure 6 Shows Figure 5 B in Figure 7 shows a driving unit according to a third embodiment of the present invention, Figure 8 shows a drive unit according to a fourth embodiment of the present invention, Fig. 9 Shows Figure 8 C in.

[0058] Reference Figure 5 and Figure 6 The driving unit 310' of the second embodiment of the present invention includes a propeller for applying airflow to the filter 200. The propeller uses the rotation force to make the dust accumulated on the filter 200 fall off, and the fallen dust returns to the melting space T due to its own weight.

[0059] Reference Figure 7 The driving unit 310" of the third embodiment of the present invention includes a hammer head for applying physical impact to the filter 200. The hammering of the hammer head causes the filter 200 to vibrate, and the vibration causes the dust accumulated on the filter 200 to fall off. Afterwards, the fallen dust returns to the melting space T due to its own weight.

[0060] In the third embodiment, the hammer head is not in contact with the filter 200, but is hammered in an up-and-down manner to contact a portion of the filter 200, thereby vibrating the filter 200. In another embodiment, the hammer head may vibrate while a portion of the hammer head is in contact with the filter 200, thereby causing dust accumulated on the filter 200 to fall off.

[0061] Reference Figure 8 and Fig. 9The driving unit 310″′ of the fourth embodiment of the present invention is driven according to the control of the driving control unit 320, so that the sliding component slides along the surface abutting against the filter 200, so that the dust accumulated on the filter 200 falls off. Thereafter, the fallen dust returns to the melting space T due to its own weight.

[0062] The present invention can prevent the dust generated when solid waste is put into a melting furnace and a large amount of water generated when liquid waste is put into the melting furnace from accumulating inside the pipe cooler.

[0063] In addition, the amount of dust exhausted through the exhaust system can be reduced, thereby avoiding the difficulty in handling the generated dust due to its scattering nature and the increase in dust handling costs, and ultimately improving the utilization rate of the melting furnace.

[0064] The above-mentioned multiple embodiments are examples for describing the present invention, and the present invention is not limited thereto. Those skilled in the art can make various modifications to the present invention based on the above, and therefore, the technical protection scope of the present invention should be defined by the attached claims.
