Hereinafter, a landfill gas switching system to which the landfill gas methane direct conversion technology related to the present invention is applied will be described in detail with reference to the drawings

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic explanatory view showing the entire configuration of a landfill gas switching system to which a landfill gas methane direct conversion technology, which is an embodiment of the present invention, is applied. As shown in FIG. 1, the landfill gas switching system using the landfill gas methane direct conversion technology, which is an embodiment of the present invention, includes a landfill gas collecting apparatus 100, an inertial collision type dust removing apparatus 200, ammonia and hydrogen sulfide removal (DME) plant, a DME storage tank 800, and a DME or refinery gas delivery vehicle 900. The apparatus 300 includes a siloxane removal unit 400, an oxygen removal unit 500, a nitrogen removal unit 600, a DME plant, Lt; / RTI >

Here, the landfill gas collecting apparatus 100 is for collecting the landfill gas generated in a landfill or the like, and serves to transfer the landfill gas buried in the ground through the pump to the ground.

Generally, the landfill gas generated from landfills is mainly composed of methane and carbon dioxide, and contains about 5 to 10% of impurities. These impurities include impurities such as nitrogen <10%, oxygen <1%, sulfur compounds 500-1000ppm, siloxane 100-150ppm, VOCs, fine dust and the like, which are impurities in DME gas or refinery gas to be finally produced It becomes an obstructive element.

In the present invention, these impurities are removed through the following apparatuses.

The primary dust and / or moisture that is removed is removed by inertial impingement type dust removal device 200. This will be described in more detail in FIG.

Then, as hydrogen sulfide and ammonia, it is removed by the ammonia and hydrogen sulfide removal device 300. A wet catalytic desulfurization technique is first applied to treat relatively high concentrations of hydrogen sulfide (<several hundred ppm) among the landfill gas trace materials. According to this method, hydrogen sulfide and ammonia in the landfilled gas are dissolved in water, and then hydrogen sulfide and ammonia are removed by converting the desulfurization catalyst into a harmless and odorless substance at normal temperature and pressure through a liquid phase oxidation reaction of the desulfurization catalyst. At this time, the removed hydrogen sulfide is converted into sulfur particles and fixed to the catalyst, and the discharged spent catalyst can be used as general waste after landfilling or as fertilizer after dehydration. On the other hand, when a Fe-based catalyst is used for the oxidation reaction of hydrogen sulfide, it is more economical than the catalyst used in the conventional liquid acid catalytic oxidation method for removing hydrogen sulfide, and no harmful waste is generated.

The siloxane is then removed by the siloxane removal apparatus 400. This will be described in more detail in FIG.

Then, the oxygen in the landfill gas is removed through the oxygen remover 500. If this oxygen is included in the refining gas at a later time, there is a fear of explosion, and furthermore, it is a constituent element for corroding the metal pipe as the transfer passage, so it should be removed. In the oxygen remover 500, oxygen may be removed using a ceramic adsorbent or oxygen may be removed using a metal oxide having an oxygen vacancy.

Particularly, in the case of the closed-skit metal oxide (ABO ₃ type oxide), A is a metal cation in the alkaline earth metal system (periodic table atomic number 57-71 cation, 1A, 2A series metal) Is maintained at +6, and is electrically neutralized by bonding with three oxygen anions (-6). If the atoms substitute for or substitute other A 'and B' atoms for A and B, then oxygen ions become insufficient to meet the electrical neutrality and thus oxygen vacancy is generated. At this time, the entire oxide crystal is electrically stable, but the lattice around the oxygen vacancy is kept electrically + state, so that when the external oxygen partial pressure is increased, oxygen is absorbed into the lattice.

This reversible oxygen production technology separates oxygen by absorbing and then desorbing oxygen using the absorber in which the oxygen vacancy is present.

The nitrogen removal device 600 is for removing nitrogen in the landfill gas. The nitrogen is adsorbed by using zeolite to remove nitrogen in the landfill gas.

In the landfill gas purification system according to an embodiment of the present invention, ammonia and hydrogen sulfide in the captured landfill gas are firstly removed through the ammonia and hydrogen sulfide removal device 200, and the ammonia and hydrogen sulfide removal device In the first cleaned landfill gas, the moisture and / or fine dust is removed through the inertial collision type dust removing apparatus 300, and the second and third purified dusts are removed by the inertial collision type dust removing apparatus 300, The siloxane in the purified landfill gas is removed by the siloxane removal apparatus 400 and the oxygen is removed by the oxygen removal apparatus 500 in the third purified landfill gas that has been thirdly purified by the siloxane removal apparatus 400, Nitrogen is removed from the fourth purified landfill gas that has been quadrature-purified by the removal apparatus 500, and the fifth purified landfill gas finally purified is generated by the nitrogen removal apparatus 600.

The fifth purified landfill gas is converted into dimethyl ether gas in the DME plant 700 and stored in the DME storage tank 800 or the fifth purified gas is separately liquefied and loaded on the purified gas transportation vehicle 900 It may be transferred to the place of use.

The first blade 320 and the second blade 330, The water contained in the first purified landfill gas is condensed and removed by the cooling water pipe 310 including the pipe 310.

On the other hand, the pair of first blocking blades 340 is installed at a connection point between the first blade 320 and the second blade, so that fine dust in the first purified buried gas collides with the blocking blade and is removed by gravity .

A second blocking blade 350 is installed at the end of the second blade 330 to remove dust by the second blocking blade 350.

In this manner, the manufactured inertial collision type dust removal apparatus 300 can simultaneously remove fine dust and moisture in the first purified landfill gas.

This flow path is connected to the first duct 411 and the second duct 413 so that the exhaust gas flowing from the first duct 411 forms a zigzag current along the flow path. As shown in the figure, the first partition 421 and the second partition 423 are inclined at an acute downward angle with respect to the horizontal direction of the housing 410, so that the contaminated dust, It can be installed to fall.

On the other hand, on the bottom surface side of the housing 410, an adsorbent discharge unit 430 is formed. This adsorbent discharging unit 430 is a device for discharging a siloxane adsorbent for removing siloxane in the second purified buried gas with the above-described jig jagged flow path. As such adsorbent, activated carbon or graphite may be used. When the adsorbent flows into the jig jagged flow path formed by the partition walls 421 and 423, the adsorbent flows along the exhaust gas along with the exhaust gas along with the exhaust gas to collect the siloxane contained in the second purification buried gas. When the siloxane dust becomes heavy (siloxane coarsening) due to the trapping, it falls on the plane of the partition wall. The dust that has fallen downward toward the bottom of the housing 410 due to gravity. At this time, they are collected in the contaminated dust storage portion 440 through the discharge port 427. Further, the siloxane dust still present on the plane of the partition wall may be dropped to the siloxane dust storage portion 440 through the impact device 480. [

On the other hand, the inertial collision device 450 may be composed of three subfilters 451 to 453 as shown in the figure. Fine dust of the first purified air can be removed through the inertial collision device 450, and more purified air can be discharged to the second duct 413.

Further, an induction fan 460 for guiding part of the air stream discharged from the second duct 413 to the adsorbent discharge unit 430 may be further installed. As a result, the adsorbent can be easily introduced into the jig jagged flow path.

The siloxane is removed from the second purified buried gas containing siloxane by the siloxane removal apparatus described above, the powder adsorbent is sprayed from the inlet, the chamber is provided to secure a sufficient time for adsorbing the gaseous contaminants, By utilizing the adsorbent until the point of breakage is reached by recirculation by gravity separation, activated carbon and graphite, which are siloxane adsorbents, can be economically utilized.

In particular, the siloxane utilizes the growth mechanism of the particles to increase the efficiency of dust collection at the rear end by colliding the generated siloxane with the particulate adsorbent to enlarge the particles.

The flow path forming portion 1100 is a means for forming the gas transfer path W in which the water containing gas G is introduced and the water removing gas G 'is discharged, and as shown in FIGS. 4 and 5, The second flow path forming portion 1130 and the third flow path forming portion 1150 may be spaced apart from each other by a predetermined distance to form the gas flow path W. [ Here, the first, second and third flow path forming portions 1110, 1130 and 1150 are only one embodiment which is provided for explaining more effectively because a plurality of flow path forming portions 1100 are provided. And a plurality of flow path forming portions 1100 capable of forming a plurality of flow paths.

This can form a zigzag gas moving path W as shown in the figure, in which the bending direction continuously changes to one side and the other side of the flow path forming portion 1100 like a wavy shape. This zigzag gas moving passage W has a larger contact area with the water containing gas G than the gas moving passage formed by the straight passage and the moisture present in the water containing gas G by the curved structure The frequency of shock to the flow path forming portion 1100 can be further improved.

The refrigerant portion 1300 is a means for accommodating the refrigerant 1310 supplied from a refrigerant supply device (not shown) inside the flow path forming portion 1100 and is formed in a plate shape corresponding to the flow path forming portion 1100 But it may be formed in a cylindrical tube shape and installed inside the flow path flow path forming portion 1100.

Accordingly, the impact protrusion 1500 can remove the moisture of the water-containing gas G through the cooling effect of the condensation by the refrigerant 1310, as well as the effect of the inertia impact when impacted with the water-containing gas (G).

The impact protrusions 1500 protrude alternately in directions facing each other on the respective surfaces of the different flow path forming portions 1100 and are formed so as to protrude from the flow path forming portions 1100, The contact area with the water-containing gas (G) and the impact frequency can be maximized.

When the moisture-containing gas G is first drawn into the flow path forming portion 1100 in the linear direction, the flow path forming portion 1100 of the inertial collision type dust removing apparatus 1000 having the above- The moisture of the water-containing gas (G) is primarily condensed on the surface of the flow path forming portion (1100) by the portion (1300). In addition, the water-containing gas (G) in linear motion is impacted by the impact protrusions (1500) protruding from the front end of the flow path forming portion (1100), and water of the water containing gas (G) Lt; RTI ID = 0.0 &gt; 1500 &lt; / RTI &gt; At this time, the impact protruding part 1500 also provides a condensing effect through the protruding coolant part 1570 to increase the water removing efficiency of the water containing gas (G), and the impact area of the water containing gas (G) through the auxiliary protruding part Can be further enlarged. The shock protruding portion 1500 provided at the front end of the flow path forming portion 1100 and the moisture containing gas G primarily impacted are moved again through the space between the impact protruding portion 1500 and the flow path forming portion 1100 do. The flow path forming portion 1100 is formed in a bent structure so that the water containing gas G continuously impacts with the bending structure and water is removed continuously by the inertia impact effect and the condensation cooling effect by the refrigerant 1310 It can be effectively removed to a minute amount of moisture. In addition, the shock protrusions 1500 are also alternately arranged in series along the flow path forming portion 1100 so that the water containing gas G is supplied to the flow path forming portion 1100 and the shock protruding portion 1500 of the curved structure, The condensed cooling effect by the condenser 1310 is applied to remove the moisture contained therein and the moisture removing gas G 'from which moisture has been removed through the discharge region of the flow path forming portion 1100 is discharged.

As shown in the figure, the impact protrusions 1500 of the inertial collision type dust removing apparatus 1000 may be formed such that the ends thereof are bent in both directions. In other words, the protrusion head portion 1550 of the shock protrusion 1500 in FIG. 4 is formed in a single structure and bent toward the water containing gas (G) drawing direction, The projection head 1550 may be composed of the first head portion 1551 and the second head portion 1553 and may be bent in different directions.

More specifically, the first head portion 1551 is bent toward the inlet direction of the water containing gas G, and the second head portion 1553 is bent in the direction of the moisture removing gas G ' As shown in Fig. By thus bending the projection head 1550 in both directions, the inertial collision type dust removing apparatus can apply various feeding directions of the water containing gas G. [

In other words, the water-containing gas G can be supplied in the direction of the existing water-containing gas (G) in the beginning, and the water-removing operation can be performed through the first head part 1551. Then, The water-containing gas G can be supplied in the opposite direction and the water-removing operation can be performed through the second head portion 1553. This is because, when the continuous supply of the water-containing gas G in a single direction is performed, the foreign matter may be generated on the impact surface of the impact protrusion 1500 and the water removal efficiency may be lowered. have. Although not shown in the drawings, it is desirable that the discharge means for discharging the moisture-removed gas to the next process should be installed in both directions.

9 is a cross-sectional view of an inertial collision type dust removing apparatus in which a shock boss is formed in a shock protrusion according to an embodiment of the present invention. The description of the same components as those of the inertial collision type dust removing apparatus of Figs. 4 and 5 will be omitted.

As shown in the figure, the protrusion extended portion 1530 of the impact protrusion 1500 included in the inertial collision type dust removal apparatus 1000 may be formed as a circular bend 1533 having an opening 1531 at one side. When the water containing gas G is introduced, the circular bend 1533 may be rotated along the internal bending structure to give a cyclone effect that is discharged to the outside. Accordingly, as the impact efficiency between the water-containing gas G and the impact protruding portion 1500 increases, the moisture removing effect can be improved.

In order to further improve such a water removing effect, an extending projection 1535 projecting along the curved surface 1555 of the round bend 1533 into which the water containing gas G is introduced may be formed.

The inertial collision type dust removing apparatus according to the above configuration can maximize the water removing efficiency by removing the water contained in the water containing gas by utilizing the cooling effect of condensation cooling by the refrigerant portion and the effect of inertia collision by the impingement projection portion.

The inertial collision type dust removing apparatus described above in the landfill gas is not limited to the configuration and the method of the above-described embodiments, but the embodiments can be applied to all or a part of each embodiment Some of which may be selectively combined. In addition, the name of the present invention is not limited to the inertial collision type dust removing apparatus in the landfill gas or the system, but can be applied to the entire heat exchanging apparatus for removing moisture.

FIG. 10 is a cross-sectional view for explaining a multiple adsorption apparatus in which an inertial collision type dust removing apparatus, an ammonia and hydrogen sulfide removing apparatus, and a siloxane removing apparatus according to an embodiment of the present invention are integrated. FIG. Sectional view for explaining a regeneration portion of a multiple adsorption apparatus for removing contaminants in the landfill gas (G) according to an embodiment.

10, the multiple adsorption apparatus 2000 may include a gas branching section 2200, a purification section, a detection sensor 2400, a gas integration section 2500, and a control section 2600.

1, the inertial impingement dust removing apparatus 200 of FIG. 1 includes a first refining column 2311 and a second refining column 2313, and the ammonia hydrogen sulfide removing apparatus 300 and the siloxane removing apparatus 400 is implemented as a third tabletting tower 2314.

The gas branching section 2200 is a means for branching the landfill gas G introduced through the incoming gas pipe P1 in different directions and includes a first branch pipe 2210, a second branch pipe 2230, Branch unit 2250. [ The gas branching section 2200 may be disposed between the landfill gas collecting apparatus 100 of FIG. 1 and the inertial collision type dust removing apparatus 200.

The first branch pipe 2210 is formed to communicate the incoming gas pipe P1 with a first purifying portion 2310 described later.

The second branch pipe 2230 is formed so as to communicate the incoming gas pipe P1 with a second purifying portion 2360 described later.

The branching unit 2250 is installed at a point of engagement of the inlet gas pipe P1, the first branch pipe 2210 and the second branch pipe 2230 to control the branching direction and the branching amount of the buried gas G. [ For example, a branch valve 2250 whose opening and closing is controlled in accordance with an electrical signal.

This branching unit 2250 may include a first valve film 2253, a second valve film 2255, and a valve shaft 2251.

The valve shaft 2251 is installed at the coupling point of the first branch pipe 2210 and the second branch pipe 2230.

The first valve shaft 2251 and the second valve shaft 2251 extend toward the incoming gas pipe P1 and are rotatably coupled to the valve shaft 2251. In other words, when the first valve film 2253 is rotated, it is rotated to the point of contact between the incoming gas pipe P1 and the first branch pipe 2210 so that the buried gas G is introduced into the first branch pipe 2210 The path can be closed or opened. The second valve film 2255 rotates to the point of contact between the inlet gas pipe P1 and the second branch pipe 2230 and the flow path of the buried gas G to the second branch pipe 2230 Lt; / RTI &gt; can be closed or opened. In addition, when the first valve membrane 2253 and the second valve membrane 2255 are coupled to be parallel to each other, each surface that is not facing each other is formed to become gradually thicker toward the valve axis 2251. When the first valve membrane 2253 and the second valve membrane 2255 are horizontally coupled to each other toward the inlet gas pipe P1, the buried gas G of the inlet gas pipe P1 flows into the first branch pipe 2210 and the second valve membrane 2255, Can branch to the same amount of gas to the 2-minute branch 2230.

The purifying section 2300 includes a first purifying section 2310 and a second purifying section 2360 as means for purifying the respective buried gas G branched in different directions when the purge gas G is introduced .

The first purifier 2310 and the second purifier 2360 have the same configuration and the first purifier 2310 is connected to the first branch 2210 and the second purifier 2360 is connected to the first purifier 2310. [ There is a difference in that it communicates with the second branch pipe 2230. Here, the internal configuration will be described as a representative of the first purification section 2310, and a description of the internal configuration of the second purification section 2360 will be omitted.

The first purifying section 2310 may include a first purifying column 2311, a second purifying column 2313, and a third purifying column 2314. Since the shapes of the respective tablet columns are substantially the same, the first tablet column 2311 will be described as a representative example, and only the differences will be described.

The first purification column 2311 is a means for primarily purifying the landfill gas G introduced through the first branch 2210. Therefore, it communicates with the first branch pipe 2210 through the lower region of the side surface. The first tabletting tower 2311 may have a hollow interior and an upper and a side thereof may be formed in a square shape, and a lower area may be formed in a square shape having a historical angle.

A first inertial impact unit 2312-1 is disposed in the inner hollow portion of the first tabletting tower 2311. [

The first inertial impact unit 2312-1 is a means for colliding moisture and dust, which are the first contaminants of the landfill gas G, to fall down. The first inertial collision units 2312-1 are arranged in parallel so as to be vertically arranged. At this time, a plurality of inertial projections 2312a are formed on the respective surfaces of the first inertia collision unit 2312-1 so as to be bent toward the direction in which the buried gas G is drawn.

The inertia projection 2312a can be formed in each of the areas of the first inertia impact unit 2312-1 which are not overlapped with each other on the mutually facing surfaces, thereby forming a zigzag pattern.

In addition, the first inertial impact unit 2312-1 may be formed so that the refrigerant flows therein. Accordingly, the first inertial impact unit 2312-1 can have a surface temperature at a low temperature state. In this case, when the landfill gas G collides with the first inertial impact unit 2312-1, heat exchange occurs so that water of the landfill gas G condenses on the surface of the first inertial impact unit 2312-1 have.

The lower region of the first tabletting column 2311 may be formed with a water collecting tank 2311a having a historical pyramid shape as described above.

The water collecting tank 2311a may be formed so as to be inclined toward the lower center portion, and the water dropped by the first inertial impact unit 2312-1 may be stored. In addition, the water collecting tank 2311a is formed of a water collecting opening / closing port 2311b which can be opened and closed in the vertex area. Accordingly, the stored moisture can be discharged to the lower part in accordance with an electrical signal.

The water collecting opening 2311b can communicate with the first collecting part 2315 through the water collecting pipe 2311c.

The first collecting unit 2315 may be connected to an external pump (not shown) as a means for discharging the water discharged from the water collecting tank 2311a to the outside.

The second tabletting column 2313 is continuously disposed in the first tabletting column 2311 and a second inertial impact unit 2312-2 is installed therein and the first adsorbent A1 can be filled. Accordingly, the second purification column 2313 is substantially the same as the first purification column 2311, but differs in that the first adsorbent A1 is filled. Therefore, the second tabletting column 2313 can drop water through the second inertial impact unit 2312-2 and collect moisture through the first adsorbent A1. That is, the water can be removed in a double manner. Here, the second inertial impact unit 2312-2 has the same structure as the above-described first inertial impact unit 2312-1.

The first adsorbent (A1) is a moisture adsorbent for removing moisture, and may include a molecular sieve, active carbon, silica gel and the like. Such a moisture adsorbent may be filled in the form of powder or granules.

The second purification column 2313 may further include a second collector 2316 for collecting the first adsorbent A1 that collects contaminants of the landfill gas G. [

Unlike the first collecting part 2315, the second collecting part 2316 collects not only water but also the first adsorbent A1 that collects contaminants of the landfill gas G. [ Therefore, the second collecting unit 2316 may include a regeneration unit 2320 for regenerating and reusing the first adsorbent A1 whose contaminants have been collected and adsorbed.

The regeneration section 2320 is a means for regenerating the adsorbent that has collected the contaminants and supplying the same again to the purification tower. The regeneration section 2320 may include a dewatering unit 2321 and a heating unit 2323 in a hollow portion of the regeneration housing formed to communicate with the collecting pipe 2311c.

The dewatering unit 2321 includes a dewatering housing 2321a that can receive the moisture and the first adsorbent A1 and can be rotated by an electrical signal, from the water collector 2311c.

The dewatering housing 2321a is formed with a dewatering opening 2321b corresponding to the collector pipe 2311c, and a hollow portion is formed in the dewatering opening 2321b. Therefore, the dehydrating housing 2312a can receive the water and the first adsorbent A1 from the collector pipe 2311c, and can receive the moisture and the first adsorbent A1.

In addition, the side surface of the dewatering housing 2321a is formed as a dewatering sidewall having a fine through-hole 2321c. At this time, the diameter of the through hole 2321c may be a diameter that allows water to pass but does not allow the first adsorbent (A1) to pass through. Accordingly, when the dewatering housing 2321a is rotated by the driving unit (not shown) in the state where the moisture and the first adsorbent A1 are accommodated, the centrifugal force acts on the moisture and the first adsorbent A1 toward the dewatering sidewall. The fine holes 2321c are formed in the dewatering sidewall so that moisture is discharged through the through holes 2321c and the first adsorbent A1 is present in the dewatering housing 2321a in a state in which moisture is removed. At this time, a space between the dewatering sidewall and the regeneration housing may be formed with a dewatering outlet 2321e for removing moisture coming out from the dewatering housing 2321a.

The first adsorbent A1 from which the moisture has been removed can be moved to the heating unit 2323 connected to the lower portion of the dewatering unit 2321 by opening the dewatering opening 2321d which is the bottom surface of the dewatering housing 2321a.

The heating unit 2323 is means for activating and regenerating the first adsorbent A1 conveyed from the dewatering unit 2321. [ Therefore, the heating unit 2323 can be heated by heating the inner space of the heating unit 2323 by burying the heating wire 2323a on the bottom surface of the heating unit 2323. In addition, the heating unit 2323 communicates with an external hot air fan (not shown), and can receive hot air from the hot air fan to heat the internal space in which the first adsorbent A1 exists. When the first adsorbent (A1) is heated by the heating unit (2323), the first adsorbent (A1) is activated so that the adsorbed capacity exhausted in the process of collecting the contaminants can be regenerated.

As described above, when the first adsorbent (A1) is regenerated in the regeneration section (2320), it can be introduced into the second purification column (2313) to reuse the adsorbent.

The second tabletting column 2313 may include a regeneration moving unit 2330 as a means for re-supplying the first adsorbent A1.

The regeneration moving unit 2330 may include a regeneration moving pipe 2331 and a regeneration pump 2333. [

The regeneration moving pipe 2331 may be formed in a tubular shape so that one end thereof communicates with the regenerating opening and closing port of the heating unit 2323 and the other end thereof communicates with the opening and closing port of the second refilling column 2313. The first adsorbent A1 regenerated in the heating unit 2323 can be moved to the second tabletting column 2313 along the regeneration moving pipe 2331. [

The regeneration pump 2333 can transfer the first adsorbent A1 along the regeneration moving pipe 2331 in an air suction manner. In other words, when the heating opening / closing port 2323b of the heating unit 2323 is opened, the regeneration pump 2333 is rotationally driven to suck the first adsorbent A1, and the sucked first adsorbent A1 is subjected to the second purification And can be discharged in the direction of the column 2313.

The regeneration moving section 2330 may further include an escalator section as a means for conveying the regenerated first adsorbent A1 to the second tabletting column 2313 although not shown in the figure.

In the escalator part, the storage part for receiving the first adsorbent (A1) is continuously installed in the refinery pipe and driven to rotate like an armored car chain. Therefore, when the first adsorbent A1 is pushed out from the heating unit 2323 toward the regeneration moving pipe 2331, the first adsorbent A1 is accommodated in the escalator part by a predetermined amount and flows toward the second purification column 2313 As shown in FIG. To this end, the heating unit 2323 may further include a pushing means capable of pushing the first adsorbent A1 toward the regeneration moving pipe 2331.

The third tabletting column 2314 is disposed continuously to the second tabletting column 2313 so that the third inertial impact unit 2312-3 is disposed therein and filled with the second adsorbent A2. Further, the second adsorbent (A2) includes a third collecting part (2317) for collecting and regenerating the contaminants when they are collected. In other words, the third purification column 2314 is substantially the same as the second purification column 2313, but differs in that the adsorbent to be filled is different from each other. Here, the third inertia impact unit 2312-3 has the same structure as the first and second inertial impact units.

The second adsorbent (A2) is an adsorbent for removing hydrogen sulfide or siloxane. The adsorbent is selected from the group consisting of Silicalite, Iron-Chelate, Oxidation Catalyst, Activated Carbon, Silica Gel ), Diatomite, activated alumina, and zeolite. The adsorbent may be adsorbed on the adsorbent.

Therefore, the third purification column 2314 can drop moisture through the light collision unit and remove hydrogen sulfide and siloxane through the second adsorbent (A2). In addition, the second adsorbent (A2) that has collected hydrogen sulfide and siloxane can be regenerated in the third collecting section (2317) and reused in the third purification column (2314).

The first purifying section 2310 according to the above configuration is configured such that water, hydrogen sulfide, and siloxane are adsorbed in the first purifying column 2311, the second purifying column 2313, and the third purifying column 2314, Can be removed. The second purification unit 2360 has the same configuration.

At this time, the first purifying section 2310 is configured such that the buried gas G flows from the first purifying column 2311 to the second purifying column 2313, from the second purifying column 2313 to the third purifying column 2314 And may include a purge gas transfer passage 2350 in a structure to be moved.

Since the purified gas moving passages 2350 are the same as each other, the purified gas moving passages 2350 formed in the first tabletting column 2311 and between the second tabletting columns 2313 will be described as an example.

The purge gas transfer passage 2350 is a passage formed by the first sidewall 2351 of the first purifier column 2311 and the second sidewall 2353 of the second purifier column 2313.

The first sidewall 2351 protrudes vertically from the bottom surface of the first tabletting column 2311. The end of the first sidewall 2351 is spaced apart from the upper part of the first tabletting column 2311 by a predetermined width.

The second sidewall 2353 protrudes in the vertical direction from the upper surface of the second tabletting column 2313 spaced apart from the first sidewall 2351 toward the bottom surface. The end of the second side wall 2353 is spaced apart from the bottom surface of the second tabletting tower 313 by a predetermined width.

The purified gas moving passage 2350 is provided between the first sidewall 2351 and the upper surface of the first tabletting column 2311 and between the second sidewall 2353 and the bottom surface of the second tabletting column 2313 As shown in Fig. The buried gas G lifted and lowered from the first refining column 2311 passes through the opening of the first sidewall 2351 and descends toward the bottom surface of the second refining column 2313, And enters the tablet column 2313. At this time, sidewall protrusions 2355 protruding to be bent toward the inlet direction of the buried gas G may be formed on the surfaces of the first sidewall 2351 and the second sidewall 2353 facing each other.

The sidewall protrusions 2355 are respectively disposed in regions that do not overlap with each other, and moisture contained in the landfill gas G can be impinged and condensed.

The detection sensor 2400 is a means for detecting the states of the first and second purification units 2310 and 2360. Since the detection sensor 2400 is installed and operated in the same structure as the first and second purification units 2310 and 2360, the detection sensor 2400 is described as a representative of the detection sensor 2400 installed in the first purification unit 2310 .

The detection sensor 2400 may include an image sensor and a weight sensor.

The image sensor is means for acquiring image information of the adsorbent. Accordingly, the image sensor can acquire image information of the adsorbent filled in the second purification column 2313 and the third purification column 2314 filled with the adsorbent in real time or at a specific period. At this time, when the lightness, the illuminance, the color, etc. of the adsorbent vary according to the degree of trapping of the pollutant, the corresponding change can be detected through the image sensor.

The weight sensor is a means for sensing the weight of the filled adsorbent and moisture. Accordingly, the weight sensors are respectively installed in the collecting tanks of the first, second, and third tablet columns 2312, 2313, and 2314, and can detect the weight change due to the adsorbent or moisture.

The gas integrating unit 2500 is a means for discharging the purified gas G from the first refining unit 2310 and the second refining unit 2360 to the discharge gas pipe P2. The gas integration unit 2500 may include a first integration pipe 2510, a second integration pipe 2530, and an integration unit 2550.

The first integrated pipe 2510 communicates with the third tablet column 2314 of the first tablet 2310 and the other end communicates with the discharge gas pipe P2. Therefore, the purified gas G that has been purified in the third purification column 2314 of the first purification section 2310 can be transferred to the discharge gas pipe P2 through the first integration pipe 2510. [

The second integrated pipe 2530 communicates with the third tablet column 2314 of the second tablet portion 2360 and the other end communicates with the discharge gas pipe P2. Thus, the purified purified landfill gas G in the third purification column 2314 of the second purification section 2360 can be transferred to the exhaust gas pipe P2 through the second integrated pipe 2530.

The integrated unit 2550 is means for guiding each of the landfill gas G refined in the first refining section 2310 and the second refining section 2360 to the exhaust gas pipe P2. Such an integrated unit 2550 may include an integral valve 2550 having the same structure as that of the above-described branch valve 2250 and reversely disposed. The integrating valve 2550 has the same configuration and operation as those of the branch valve 2250, so a detailed description thereof will be omitted.

The control unit 2600 is means for controlling the structures that are operated by electrical signals among the above-described structures. In other words, the control section 2600 can control the gas branching section 2200, the regeneration section 2320, the regeneration moving section 2330, and the integrator according to the state information of the refining section. The state information of the purification unit 2300 is information received from the detection sensor 2400 installed in the purification unit 2300. Therefore, the level information of the purification tower and the adsorbent information may be state information.

Further, the control unit 2600 can control the refrigerant flowing into the plurality of inertial impact units 2312. [ In other words, it is possible to selectively control the refrigerant to be supplied to each of the inertia collision units 2312 according to the input information of the user or the driving state of other devices.

Hereinafter, an operation method of the adsorption apparatus 2100 under the control of the control unit 2600 will be described.

When the landfill gas G is first introduced through the incoming gas pipe P1, the controller 2600 determines the states of the first and second refiner units 2310 and 2360 and controls the operation of the branch unit. The states of the first and second purification units 2310 and 2360 can be determined by determining whether the detection values received from the detection sensors 2400 installed in the respective purification columns meet the reference value.

Therefore, when it is determined that the states of the respective refineries are all good, the control unit 2600 opens all of the branch valves 2250 to discharge the landfill gas G through both the first refiner 2310 and the second refiner 2360, Can be carried out.

Thus, the level information of the first purification section 2310 (arbitrarily selected for the sake of explanation) or the state information of the adsorbent may exceed the reference value while the purification of the landfill gas G is being performed.

In this case, the controller 2600 may control the branch valve 2250 to regulate the level of the adsorbent or regenerate the adsorbent to block the buried gas G introduced into the first purifier 2310. The control unit 2600 may also control the integrating valve 2550 to close the path of movement between the first purifying unit 2310 and the exhaust gas pipe P2.

According to the above control, the first purifier 2310 is disconnected from the respective gas pipes by the branch valve 2250 and the integration valve 2550. Conversely, since the second refiner 2360 is in continuous communication with the outgoing gas pipe and the exhaust gas pipe P2, continuous refining operation can be performed.

When the refining operation of the first purification unit 2310 is stopped, the control unit 2600 may open the collecting opening and closing unit and move the collected water and the adsorbent to the collecting units. In the case of the first purifying column 2311, the first collecting unit 2315 collects only water and dust, and therefore can discharge the water and dust directly.

The second purification column 2313 and the third purification column 2314 collect moisture, the first adsorbent A1, and the second adsorbent A2 in respective collecting portions. Therefore, the control unit 2600 can drive the regeneration unit 2320 to dehydrate the water and operate the adsorbent regeneration to heat the adsorbent.

Thereafter, when the regeneration of each adsorbent in the second collecting portion 2316 and the third collecting portion 2317 is completed, the control portion 2600 drives the regeneration moving portion 2330 to regenerate the regenerated adsorbent To be fed back into the purification tower.

The control unit 2600 controls the branch valve 2250 and the integration valve 2550 to be opened toward the first purification unit 2310 when the regenerated adsorbent is reintroduced.

Accordingly, the landfill gas G which has been refined only in the second refiner 2360 can be further refined into the first refiner 2310 and the second refiner 2360, respectively.

12 is a cross-sectional view for explaining an impact pretreatment apparatus which integrally implements an inertial collision type dust removing apparatus, an ammonia and hydrogen sulfide removing apparatus, and a siloxane removing apparatus according to an embodiment of the present invention.

1, the inertial impingement dust removing apparatus 200 of FIG. 1 is implemented as a first impingement unit 3150, and the ammonia hydrogen sulfide removing apparatus 300 and the siloxane removing apparatus 400 are installed in the second minute And is used as an in-use unit 3160.

12, an inflate pretreatment apparatus 3100 for removing contaminants in biogas includes a housing 3110, a partition wall 3120, an inlet 3130, a discharge unit 3140, an active fiber filter The first inertia impact plate 3141, the first inertia impingement unit 3150, the second inertial inflation unit 3160, the fourth collecting unit 3170, the fourth regenerating unit 3180, The second inertia collision plate 3201, the fifth collecting portion 3210, the fifth regeneration portion 3220, the fifth supply portion 3230, the first sensor (not shown) 3240, a second sensor 3250, and a control unit 3260.

The housing 3110 may have a space for removing contaminants contained in the biogas.

The partition 3120 can partition the inner region of the housing 3110 into an upper space and a lower space. One end of the barrier rib 3120 may be coupled to the housing 3110 and the other end may be spaced apart from the housing 3110. The biogas that has passed through the lower space can be moved to the upper space through the spaces provided separately.

The partition wall 3120 may have a space therein and may store the first adsorbent supplied to the first dividing inflation part 3150. [ The first adsorbent may be supplied to the inner space of the partition 3120 through the first supply part 3190. [ The first adsorbent is a moisture adsorbent for removing moisture, and may include a molecular sieve, an active carbon, a silica gel, and the like. For example, the first adsorbent may be a hydrophilic activated carbon powder.

The inlet 3130 is coupled with the housing 3110 and can introduce the biogas into the lower space.

When the discharge portion 3140 is coupled with the housing 3110, the biogas that has passed through the upper space can be discharged.

The first minute inflator portion 3150 may be provided at a lower portion of the partition wall 3120. The first minute in-use unit 3150 can spray the first adsorbent adsorbed on the first pollutant in powder form. The injected first adsorbent adsorbs the first contaminant and falls in the direction of gravity. For example, the first adsorbent may be a material that adsorbs moisture. (Not shown), which is communicated between the partition 3120 and the first distributing inflator 3150, or manually controlled by the user or controlled by the controller 3260. The first adsorbent may be stored in the partition 3120 and may be supplied to the first minute inflator 3150.

The first flow path forming portion 3155 may form a path for moving the biogas so that the biogas flowing into the inlet 3130 can move in a zigzag manner. For example, the first flow path forming portion 3155 may be formed to extend from the partition wall 3120 between the first distributing inflating portions 3150, or may extend from the inside of the lower surface of the housing 3110 have. When the first adsorbent is formed to extend from the inner surface of the lower portion of the housing 3110, the first adsorbent adsorbed on the first pollutant can be moved to the fourth collecting unit 3170 by forming a space therein.

The second minute inflator portion 3160 may be provided below the uppermost surface of the housing 3110. In this way, the second atomizing unit 3160 can be installed at a position where the second adsorbent can be injected into the upper space of the housing 3110. The second minute inflator part 3160 can spray the second adsorbent adsorbed with the second pollutant in powder form. The injected second adsorbent adsorbs the second pollutant and drops in the gravitational direction. For example, the second adsorbent may be a material that simultaneously adsorbs hydrogen sulphide and siloxane.

The fourth supply part 3190 can supply the first adsorbent regenerated by the fourth regeneration part 3170 to the first distributing inflator part 3150. For example, the fourth supply portion 3190 may be embodied in various types of devices, such as a mechanical transfer portion capable of supplying the first adsorbent, or an air suction device or an air blower.

The gas moving part 3200 is provided in a space between the partition 3120 and the housing 3110 and can move the biogas from the lower space to the upper space. For example, the gas moving part 3200 may be implemented in various forms such as a hole, a tube shape, or the like through which the biogas can pass. For example, when the gas moving part 3200 is provided in the form of a tube, the first inertia collision plate 3201 is provided inside the tube, and the first contaminant contained in the biogas is collided and dropped . For example, the first contaminant may be fine moisture.

The fifth collecting part 3210 is coupled to the housing part 3110 and is capable of collecting the second adsorbent impinging on the partition wall 3120 by being sprayed from the second partitioning inflator 3160. The second adsorbent can adsorb the first contaminant contained in the biogas in the upper space of the housing part 3110. The partition wall 3120 may be inclined at a predetermined angle so that the second adsorbent injected from the second dispersive inflating portion 3160 can be easily collected by the fifth collecting portion 3210.

The fifth regeneration unit 3220 can regenerate the second adsorbent collected in the fifth collecting unit 3210. [ The fifth regenerating unit 3220 may include an opening and closing unit (not shown), and the control unit 3260 may open and close the opening and closing unit (not shown) as needed to move the second adsorbent to the fifth regenerating unit 3220 have. For example, the fifth regeneration unit 3220 may include a rotating unit for physically dropping the first contaminant from the first adsorbent and a first heating unit for removing the first contaminant by heating the first adsorbent that has passed through the rotating unit The detailed description thereof will be omitted because it has already been described with reference to FIG.

The fifth supply part 3230 can supply the second adsorbent regenerated by the fifth regeneration part 3220 to the second distributing inflator part 3160. For example, the fifth supply portion 3230 may be embodied in various types of apparatuses, such as a mechanical transfer unit capable of supplying the second adsorbent, or an air suction unit or an air blower unit.

The first sensor 3240 can detect the amount of passage of the biogas passing through the inlet 3130.

The second sensor 3250 can detect the amount of passage of the biogas passing through the gas moving part 3200.

The control unit 3260 may control the configurations included in the ap- plitation preprocessing apparatus 3000 as a whole. For example, the control unit 3260 may control the flow of the biogas detected from the first sensor 3240 and the second sensor 3250 to the first divided inflation unit 3150 and the second divided inflation unit 3250, The amount of the first adsorbent and the amount of the second adsorbent that are injected from the first adsorbent 3160 can be adjusted. As another example, the control unit 3260 can control opening / closing of an opening / closing unit (not shown).

The inflator pretreatment apparatus according to this embodiment can increase the adsorption efficiency by maximizing the contact area between the adsorbent and the contaminants by removing the contaminants by spraying the adsorbent in powder form.

In addition, the inflate pretreatment apparatus can continuously increase the adsorption efficiency by sufficiently spraying the powdery adsorbent on the moving path of the biogas to sufficiently secure the adsorption time of the adsorbent and contaminants.

In addition, the inflate pretreatment apparatus can prevent an unnecessary amount of the adsorbent from being injected by adjusting the amount of the adsorbent to be injected according to the amount of the introduced biogas.

In addition, the inflate pretreatment apparatus can regenerate and use the adsorbent adsorbing contaminants, thereby significantly reducing the maintenance cost.
