Described activated carbon adsorber 1 is made of following part: main body 10, and it is long in one direction cuboid; Peristome 11, it is located at the upper surface of main body 10; Cap 12(figure 1 illustrates the state and two kinds of the states that cap 12 is installed that unloads lower cover portion 12), it is located at described peristome 11; And described fume pipe 7, it is located at the bottom surface 13 of main body 10.In main body 10, above the wall 10a of a side adjacent with described filter dust collector 4, be provided with a plurality of connected entrances 54.And, be provided with activated charcoal 2 in the bottom surface 13 of main body 10.Activated charcoal 2 can be changed from described peristome 11 by opening cap 12.The export mouth of the opening 7a(clean gas of 13 fume pipe 7 in the bottom surface) is provided with the supporting structure 16 of activated charcoal 2 on every side.This supporting structure 16 is that the beam 17 that shaped steel such as I shaped steel are constituted is welded into cubic shaped as frame shape, and welds airtightly with respect to bottom surface 13.
And activated carbon adsorber 1 need have such structure: the untreated flue gas by active carbon layer 21 can not spill between the bottom surface 13 of the main body 10 of activated charcoal 2 and activated carbon adsorber 1 substantially.
Be provided with the liner 19 of cubic shaped as frame shape at the end face 18 of supporting structure 16.For withstand high temperatures gas, these liner 19 employing heat resisting temperatures are 200 ℃ silicon.Its section is bar shape, rectangle or square.Being provided with the protuberance that is configured to cubic shaped as frame shape around the lower surface of the flange 22a of box framework 22 is rigid elements such as pole stock 20(solid round rod, hollow round bar).This pole stock 20 is welded on the lower surface of flange 22a with airtight conditions.When activated charcoal 2 was stated from active carbon layer 21, pole stock 20 was absorbed in described liner 19, made space between activated charcoal 2 and the fume pipe 7 keep airtight and was isolated with respect to the outside.And, because the flexibility height of liner 19 even therefore described pole stock 20 is out of shape slightly, also can absorbs this distortion and keep air-tightness.Preferably, the width of liner 19 is wideer than the diameter of pole stock 20.Thus, even the skew of a spot of position takes place, also can keep the air-tightness of activated charcoal 2 when with crane activated charcoal 2 being set.In addition, activated charcoal 2 disposes three in main body 10, yet is not limited thereto.
As shown in Figure 6 and Figure 7, the structure of activated charcoal 2 is made of following part: box framework 22; Active carbon incorporating section 24, its girder construction 23 by the thin case shape of rectangle constitutes; One group of parallel gas is by face 25, and it is to be located at the punch metal of 24 both sides, active carbon incorporating section or reticular lamina etc. and to have aeration; Shutter 26, it is used for the restriction gas flow; Cap 27, it uses in the taking-up of carrying out active carbon layer 21 with when putting into; Active carbon layer 21, it is by 24 filling granular active carbons form to the active carbon incorporating section; And steel wool 28, it is accommodated in the top of active carbon layer 21.For the liquidation (babbling) that prevents granular active carbon, on one side shown in active carbon layer 21 apply vibration or compress filling densely with bar etc. with vibrator on one side.Shown in active carbon incorporating section 24 in box framework 22, separate certain intervals and be provided with four row.The top in the first active carbon incorporating section 24a and the space of the second active carbon incorporating section 24b is connected by shutter 26 and covers.The bottom in the second active carbon incorporating section 24b and the space of the 3rd active carbon incorporating section 24c is connected by shutter 29 and covers.The top in the 3rd active carbon incorporating section 24c and the space of the 4th active carbon incorporating section 24d is connected by shutter 28 and covers.
And the first active carbon incorporating section 24a and the 4th active carbon incorporating section 24d dispose with respect to the madial wall of box framework 22 spaced apartly.And the bottom of the first active carbon incorporating section 24a and the 4th active carbon incorporating section 24d is connected by shutter 30 with the lower end of box framework 22 and covers.Thus, the space of the madial wall of the space of the space of the madial wall of box framework 22 and the first active carbon incorporating section 24a, the second active carbon incorporating section 24b and the 3rd active carbon incorporating section 24c and the 4th active carbon incorporating section 24d and box framework 22 becomes dusty gas path 31.And the space of the space of the first active carbon incorporating section 24a and the second active carbon incorporating section 24b, the 3rd active carbon incorporating section 24c and the 4th active carbon incorporating section 24d becomes clean gas path 32.And, shown in dusty gas path 31 opening on activated charcoal 2, clean gas path 32 is in the lower aperture of activated charcoal 2.According to shown in structure, the main flow direction (to flowing of thickness direction) that becomes the flue gas in the main flow direction of the flue gas in dusty gas path 31 and the clean gas path 32 and the active carbon layer 21 is the so-called lateral flow of quadrature roughly.
In addition, lift-launch is not limited thereto in the quantity of the active carbon incorporating section 24 of an activated charcoal 2.For example, also can increase to six by the quantity with active carbon incorporating section 24 forms four dusty gas paths 31 and forms three clean gas paths 32.Quantity by active carbon incorporating section 24 and shown in shutter 26,29 combinations, can form various structures.
And, about active carbon incorporating section 24, structurally, flue gas to be flowing in upper end 24f slow.Granular active carbon produces heat because of the absorption of harmful substance, if slowly then there is the danger of burning in flowing of flue gas along with the development of accumulation of heat.Therefore, by at the upper end of active carbon incorporating section 24 24f steel wool 28 being set, even in the 24f accumulation of heat of the upper end of active carbon incorporating section 24, there is not the danger of spontaneous combustion yet.And, inner surface and active carbon layer 21 both sides of the cap 27 of steel wool 28 and active carbon incorporating section 24 are close to.Steel wool 28 shapes freely change, and by its whole elastic force granular active carbon are pressurizeed.Thus, even under the situation that gas passes through, also be difficult to cause liquidation at active carbon layer 21 the removing efficient and can not reduce of harmful substance in granular active carbon.Thereby, can be to remove harmful substance more in the past than the loading of the granular active carbon that lacked.
Preferably, the thickness of the active carbon layer 21 of active carbon incorporating section 24 is 30mm～100mm.This be because, the not enough 30mm of the thickness of active carbon layer 21, the slide that flue gas then takes place is escaped, to the degradation of removing of harmful components, and thickness surpasses 100mm, then exists active carbon layer 21 accumulation of heats and the danger of burning.And the height of active carbon incorporating section 24 and depth can at random be determined.Described height and depth are for example in the scope of 500mm～3000mm.Because flow velocity and structure aspects, preferably the width of dusty gas path 31 and clean gas path 32 (size on the thickness direction of active carbon layer 21) is in the scope of about 20mm～300mm.
And, exist because filled the situation that granular active carbon gas is heaved by face 25 (shown in broken lines in Fig. 7) to active carbon incorporating section 24.When gas was heaved by face 25, the thickness of active carbon layer 21 was no longer certain, and described dusty gas path 31 and clean gas path 32 narrow down, and existed the situation that efficient produces baneful influence of removing to the pressure loss of activated charcoal 2 and harmful substance.Therefore, as shown in Figure 7, at this activated charcoal 2, the central authorities by face 25 are provided with the intermediate support spare 33 that is made of rigid element at gas.The gas that this intermediate support spare 33 is pressed active carbon incorporating section 24 is by face 25, prevents that gas from heaving by face 25.And, also can a plurality of intermediate support spares 33 be set sky with opening certain intervals.
Owing to reasons such as intensity, durability, ease of manufacture, preferably, the box framework 22 of activated charcoal 2 is that ordinary steel, stainless steel, aluminium etc. are metal.And owing to reasons such as air permeability, durability, weight, preferably, gas forms aeration height, thin (thickness is about 1mm) and light shapes such as the wire netting that is made of above-mentioned material, punch metal by face 25.And, preferably, active carbon incorporating section 24 be shaped as cuboid, as long as but have one group of parallel gas by face 25, also can be other shapes.By disposing one group of gas abreast by face 25, can make flue gas flow through active carbon layer 21 equably, can improve the efficient of removing of harmful substance.
Use under the fastening fixing situation of screw bolt and nut at the parts of the box framework 22 that will constitute activated charcoal 2, preferably, the fastening part of screw bolt and nut is implemented sealing.Thus, can prevent that gas from leaking from the fastening part of screw bolt and nut.Described cap 26 can open and close, and unexpectedly opens preventing with bolt etc. is fixing.
Described granular active carbon can adopt a certain in broken charcoal, particle charcoal, forming charcoal (granulation charcoal), the spherical carbon.The difference of the shape and size of columned forming charcoal is little, cost is also low, therefore is suitable for most the manufacturing of granular active carbon.And, also can with to adsorb the harmful substance of removing and add medicine or metal to granular active carbon accordingly.
Preferably, the size of granular active carbon is particle diameter in (granularity more than 8 orders (mesh) below 32 orders) below the above 2.4mm of 0.5mm.In activated carbon adsorber 1, in order to prevent the generation of liquidation, adopt particle diameter at the granular active carbon of (granularity is below 5 orders) more than the 4mm mostly, but, because dioxin etc. is attracted to the near surface of activated carbon granule, thereby the granular active carbon that particle diameter is little then the contact area with the flue gas of unit volume is more big, it is more high to remove efficient.Thus, preferably, particle diameter is less than 2.4mm.On the other hand, if the not enough 0.5mm of the particle diameter of granular active carbon is difficult to make the gas corresponding with it by face 25, it is therefore preferable that particle diameter is more than 0.5mm.
