Description

Clean filter

Technical Field

The present invention relates to a clean filter, and more particularly, to a clean filter which is advantageous for a harmful substance removing apparatus for an incinerator.

Background

In general, in the process of burning garbage in a high-temperature atmosphere of an incinerator, harmful substances such as sulfuric acid gas, carbon monoxide, phenol, nitrogen, chlorine, dioxin, and the like are generated. Therefore, a harmful material remover for removing harmful materials is attached to the incinerator.

The harmful substance remover generally removes harmful substances using a filter made of a solid filter material for acid removal, a solid filter material using activated carbon zeolite, or the like.

However, the conventional harmful material remover cannot effectively remove various harmful materials, and cannot actually completely remove the harmful materials. Further, the conventional harmful material remover has a disadvantage that high costs are required in manufacturing and installation of the device.

ADVANTAGEOUS EFFECTS OF INVENTION

According to the clean filter and the harmful substance remover for the incinerator using the same of the present invention, the harmful substance of the incinerator can be completely removed in the harmful substance remover by using the block-shaped clean filter prepared by blending materials of tourmaline, volcanic ash, sulfur, salt, etc. according to a predetermined ratio, so that the health of the user can be prevented from being affected by the harmful substance of the incinerator, the generation of environmental pollution can be prevented, and the cost can be reduced.

In addition, since most of incineration plants currently used cannot remove pollution, toxins, dioxin, etc. generated when incinerating garbage well, malodor and toxins caused by heat cause damage to surrounding residents, and in order to prevent such damage, a harmful substance remover is further provided in a composite structure, thereby consuming much expenses in terms of installation and maintenance management.

In addition, when the conventional incinerator is used for incineration, the temperature atmosphere must be increased to 800 ℃ or higher, and thus secondary pollution is caused by heat discharged from the chimney at a temperature of 800 ℃ or higher. However, if the clean filter of the present invention is used, the temperature of the heat of the exhaust gas discharged from the stack can be made 100 ℃ or lower, and thus no pollution is generated.

Also, according to the present invention, relatively large heat energy is stored between the incineration furnace and the harmful material remover connected to the incineration furnace and is applied to the heat exchanger or the like, whereby electricity can be produced using heat or steam generated at the time of incineration.

Detailed Description

Hereinafter, a cleaning block and a harmful material remover for an incinerator using the same according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, the cleaning block 100 of the present invention includes: a block body 10 and a plurality of materials, which are formulated in a predetermined ratio to form the block body.

The block body 10 is formed in a predetermined size and shape. The block body 10 may be directly manufactured from a semi-solid state material such as a rectangular parallelepiped, a sphere, or a polygon, or may be manufactured by being placed in a frame or a mold.

Also, the block body 10 may be provided with a through hole 20. The through-holes 20 may be positioned and sized according to the volume of the harmful material per unit time, the flow rate, and the shape of the block body 10.

The material of the block body 10 includes tourmaline, loess, volcanic ash, sulfur, and salt. The material constituting the block body 10 may further include limestone, mortar, sand, and sawdust.

Tourmaline (tourmaline) is borosilicate having hexagonal columnar crystals, and is a natural mineral belonging to the hexagonal type. Tourmaline has a property that crystallization itself generates electricity, and thus is called tourmaline or is used as a dielectric. If such tourmaline is used, the cleaning filter discharges electricity at the cathode or gap through the tourmaline and causes negative ion fluctuation, thereby performing a fusion function of removing moisture. As described above, tourmaline is eliminated by absorbing chlorine, nitrogen, phenol, dioxin, and the like by causing toxic substances such as carbon monoxide, sulfuric acid gas, and the like generated in exhaust gas of an incinerator or soot to collide with a clean filter and descend. When a plurality of materials are blended, the tourmaline is crushed into fine powder.

Loess has very excellent effects of releasing negative ions, releasing far infrared rays, adjusting humidity, deodorizing, neutralizing toxicity, etc. The loess contains silicon oxide, aluminum oxide, sodium oxide, potassium oxide, iron oxide, etc., and among the plurality of elements, iron oxide or silicon oxide is a main component in terms of weight percentage, and the color thereof is determined according to the content of iron oxide or aluminum oxide. Preferably, the particle size of the sulfur degree is in the range of 0.1 to 80 μm.

Pozzolans are siliceous materials (volcanic dust) generated during the chalky period, which do not solidify autonomously but react with a stimulant in the presence of heat and water to generate compounds of low solubility and cause various chemical actions and effects according to the reaction, and belong to active rocks.

The volcanic ash can be replaced by clay mineral composed of silicate, alkali, aluminum, etc. as main components.

The sulfur and the salt play a role in eliminating toxins in harmful substances or neutralizing the harmful substances together with the tourmaline and the volcanic ash. The sulfur may include a sulfur compound having a sulfur-sulfur structure. Salt refers to salty crystals containing sodium chloride as a main component.

The cleaning filter containing the tourmaline, the volcanic ash, the sulfur and the salt can completely remove moisture or harmful substances generated when garbage is incinerated in the temperature range of 100-600 ℃. The clean filter can adsorb and remove harmful substances by expanding its own pores. Also, the cleaning filter can improve the far infrared ray release rate as compared with the existing case using loess or the like. Also, the clean filter provides an environment for rapidly transferring heat generated in tourmaline by synthesis with special carbon, thereby blocking various toxic substances generated when various wastes are incinerated, and performing elimination and neutralization.

Preferably, the blending ratio of the tourmaline, the loess, the volcanic ash, the sulfur and the salt is 15 to 25%, 5 to 15% and 3 to 7% in the stated order. In this case, the remaining portion of the blending ratio may be satisfied by at least one of limestone, mortar, sand, sawdust.

When limestone, mortar, sand and sawdust are added, the blending ratio of each material is 5 to 15%, 5 to 15% and 3 to 7% in this order. In this case, a plurality of materials, such as tourmaline, loess, volcanic ash, sulfur, salt, etc., which respectively serve a main function, can be effectively supported and formulated.

As a result of the experiment, when the blending ratio of the plurality of materials is within the above range, it was confirmed that the harmful substances were effectively removed. In particular, most preferably, the block body of the clean filter comprises, by weight, 20% tourmaline, 20% loess, 10% volcanic ash, 10% sulfur, 10% limestone, 10% mortar, 10% sand, 5% salt, 5% sawdust.

Table 1 shows the formulation ratios of the clean filter material as described above.

TABLE 1

Clean filter material	Blending ratio range	Optimal blending ratio (weight percentage)
			Yellow soil	15～25	20
Limestone	5～15	10
			Mortar	5～15	10
Tourmaline	15～25	20
			Sulfur	5～15	10
Sawdust (chaff)	3～7	5
			Volcanic ash	5～15	10
Salt (crude salt)	3～7	5
			Sand	5～15	10

In the blending of the material for the clean filter, if the blending ratio or the content is not proper, the particles of the clean filter are broken or the clean filter cannot work normally when the speed (flow velocity) of the heat or smoke generated when the garbage is incinerated fluctuates. In this case, the toxic substances generated when the garbage is incinerated cannot be well purified and discharged to the outside of the chimney, i.e., the outside of the flue, thereby causing pollution problems and problems of human health damage, and requiring thorough guidance by experts.

As shown in the photograph of fig. 3, the cleaning block 100 of the present invention includes materials mixed in a predetermined ratio to constitute the block body 10 and the block body. The block body 10 is formed with a through hole 20. Such through-holes 20 may be omitted depending on the size or shape of the block body 10. Fig. 3 (a) is a perspective view of the cleaning filter viewed from slightly above the front, and fig. 3 (b) is a perspective view of the cleaning filter viewed from above.

As shown in fig. 4, the incineration system including the harmful material remover using the cleaning filter of the present invention includes an incineration furnace 200, a dust collector 300, and a harmful material remover 400, the dust collector 300 for collecting dust from soot discharged from the incineration furnace 200, and the harmful material remover 400 for removing harmful materials from the soot discharged from the incineration furnace 200 or the soot discharged after the dust collector 300 collects dust. The harmful material flowing into the harmful material remover 400 flows inside the harmful material remover 400 according to the flow of the air and the heat supplied from the burner 500.

Although the embodiment has been described in which the incinerator system of the present embodiment includes the dust collector 300, the present invention is not limited thereto. The present invention can greatly improve the harmful material removing performance by using the cleaning filter in the harmful material remover 400, so that the incinerator system in which the dust collector 300 is omitted can be manufactured.

As shown in a partial sectional view in fig. 5, the harmful material remover 400 may include cleaning

filters

100a, 100b, 100c, 100d having different sizes therein. The plurality of cleaning filters may be provided in such a manner that harmful substances are completely removed in the process of forcibly discharging the soot, which flows in through the suction pipe 465, through the exhaust pipe 455 in the process of heating the soot by the burner 500.

Therefore, the

clean filters

100a, 100b, 100c, and 100d can be arranged in a multi-layer form in the separately manufactured case 410. Also, the plurality of cleaning filters may be formed in a shape having a size gradually increased along a flow path from the suction pipe 465 to the exhaust pipe 455.

For example, the first cleaning filter 100a is adjacent to the intake pipe 465 provided with the inflow port and is smaller in size than the other cleaning filters. Also, the fourth cleaning filter 100d, which is disposed adjacent to the exhaust pipe 455 provided with the outflow port or the exhaust port with one end or a group of

other cleaning filters

100b, 100c disposed between the first cleaning filters 100a, may have a larger maximum size than the cleaning filters.

According to such a structure of the cleaning filter, the relative density of the cleaning filter will be large at the upstream portion of the harmful material remover 400 adjacent to the suction pipe 465. Therefore, the flow of the fluid containing the harmful material is well maintained and the harmful material can be perfectly removed by cleaning the filter.

On the other hand, a shunt tube 460 connected to the suction pipe 465 and distributing the fluid or the diffused fluid flowing from the suction pipe 465 to the upper side of the first cleaning filter 100a may be provided. The shunt tube 460 serves to distribute the harmful material-containing fluid evenly or practically evenly to the inflow surface of the first cleaning filter 100a blocking the flow path of the harmful material-containing fluid flowing in through the suction duct 465, achieving effective use of the plurality of cleaning filters in the first cleaning filter 100 a. This also affects the balanced use of the second, third and fourth

clean filters

100b, 100c, 100d, thereby improving overall efficiency and performance.

The plurality of

clean filters

100a, 100b, 100c, and 100d at each end or group are arranged in a multi-layer manner in the housing while maintaining an appropriate distance in the housing by a coupling structure of the housing, the coupling structure of the housing including: a support frame 420 provided to protrude from an inner edge of the case 410 to a center portion thereof by a predetermined length; and a partition screen or plate-shaped mesh 430 coupled to the support frame 420 so as to cross the hollow portion of the case 410. The number of layers may vary depending on the specification of the incinerator.

Also, the distance between the cleaning

filters

100a, 100b, 100c, 100d may be determined according to the capacity of the incinerator, or may be determined in consideration of the speed and capacity of soot flowing in through the suction pipe 465 on the basis of the capacity of the incinerator.

A heat-resistant insulating material 440 may be disposed on the inner wall of the case 410 between the inner wall and the clean filter. Preferably, the heat-resistant insulating material 440 is made of a material that does not chemically react with the clean filter and is filled so as to seal the space between the inner wall of the case and the clean filter.

A cover 450 detachably covering an opening of the case may be provided at an upper end of the case 410.

According to the embodiment, a clean filter capable of being semi-permanently used by being disposed once and a harmful material remover using the same will be provided. That is, in the currently used incinerator, the filter through which soot passes is frequently replaced due to its very short use time, and thus costs (filter purchase cost, labor cost generated when replacing the filter, etc.) are generated, thus being inefficient, but the clean filter of the present embodiment has semi-permanent characteristics, thus solving the problems of the conventional filter.

In addition, the conventional filter is not only inconvenient to use but also cannot solve pollution and public hazards well, but the clean filter of the embodiment can completely remove harmful substances. Furthermore, since the clean filter can be manufactured with high performance and low cost, it can be installed at a cost which cannot be lower than that of the conventional incineration facility in the case of a completely new system of the incinerator.

While the present invention has been described with reference to the preferred embodiments, those skilled in the art will appreciate that various modifications and changes can be made to the present invention without departing from the spirit and scope of the invention as set forth in the appended claims.
