Abstract
The utility model discloses a grid type denitration catalyst modeling body, which includes a cuboid casing made of a denitration catalyst and inner square passages, and is characterized in that the square passages are sequentially arrayed in the horizontal and vertical directions to the cuboid casing; warp belts are connected between the upper side wall and the lower side wall of each square passage, and weft belts are connected between the left side wall and the right side wall of each square passage; the warp belts and the weft belts are crossed to form grids; air holes are distributed on the warp belts and the weft belts. According to the utility model, the contact superficial area of the catalyst modeling body and the gas to be catalyzed is large, the contact time is long, and the catalytic effect is good.
Description
Technical field
The utility model relates to the structure of the moulding body of catalyst, in particular to the moulding body of a kind of grid type denitrating catalyst.
Background technology
Power plant, boiler are used coal fuel can produce the various oxides of nitrogen after burning, if these oxides are not effectively processed, are discharged to the serious contaminated environment of meeting in air.Therefore tackling combustion tail gas carries out denitration processing.Denitration at present generally adopts selective catalytic reduction (SCR), and the method need to be used denitrating catalyst.Denitrating catalyst is generally made into catalyst material the moulding body of structure, then makes flue gas carry out catalysis by moulding body.The moulding body of existing denitrating catalyst is generally rectangle, inner by square passageway, at level and vertical direction, be arranged in order and form, in use, allow flue gas pass through square passageway, in this process, flue gas contacts with the catalyst material of square passageway sidewall, thereby completes denitration catalyst.But the moulding body of the catalyst of this structure is because catalyst material exists only in the sidewall of square passageway, surface area is relatively little, and square passageway inside does not have other structures to stop flue gas, flue gas footpath is straight through the speed of square passageway, relatively short time of contact with catalyst material, the moulding body of this structure makes catalytic effect poor.
utility model content
The purpose of this utility model is to provide the moulding body of a kind of grid type denitrating catalyst, and the moulding body of this catalyst and catalyzed gas contact surface area are large, and time of contact is long, excellent catalytic effect.
For achieving the above object, the utility model is taked following technical scheme:
The moulding body of a kind of grid type denitrating catalyst, comprise the cuboid shell and the inner square passage that by denitrating catalyst, are made into, it is characterized in that, described square passageway is arranged in order in the horizontal and vertical directions to described cuboid shell, between the top and bottom sidewall of each square passageway, be connected with band, between the sidewall of left and right, be connected with latitude band, the staggered formation grid of band and latitude band is distributed with air-vent on band and latitude band.
Preferably, the grid that described band and latitude band are staggered to form is spaced apart along the length direction of described square passageway, distance between adjacent two grids equals the width of square passageway, and band and latitude band in each square passageway on same grid are three.
In technique scheme, in square passageway, band and the latitude band of being made by catalyst material set up at interval, and be staggered into grid by the two, not only can increase the contact surface area of catalyst material and reactant, and can rationally stop the speed that reactant gas advances, increase and catalyst time of contact, reaction is carried out more thorough.Air-vent on grid can make reactant gas pass through and contact with air-vent inner catalyst material, further strengthens catalytic effect.
Accompanying drawing explanation
Fig. 1 is the utility model outside drawing;
Fig. 2 is the utility model front view;
Fig. 3 is square passageway internal structure schematic perspective view.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, Figure 2 and Figure 3, the moulding body 1 of catalyst is all made by denitrating catalyst material, generally first denitrating catalyst material is made to pasty state, then through appearance, calcine moulding and obtain again.The moulding body of catalyst has cuboid shell, and inside is arranged in order in the horizontal and vertical directions by square passageway 2, until cuboid shell has formed square passageway array.In square passageway 2, be provided with the band 6 and the latitude band 5 that is connected left and right sides wall that connect upper and lower two side, in band 6, leave air-vent 4, on latitude band 5, leave air-vent 3, the crisscross formation grid of band 6 and latitude band 5.This grid is spaced apart along the length direction of square passageway 2, and the distance between adjacent two grids equals the width of square passageway 2.The moulding body of this catalyst can extend reacting gas and the moulding body of catalyst time of contact, also can increase the surface area that the moulding body of catalyst contact with gas simultaneously, is conducive to the carrying out of reaction with complete.With regard to the catalyst material of identical component, catalytic effect can improve more than 7%.
The present embodiment is an explanation to the utility model design and realization just, is not limited, and under the utility model design, the technical scheme converting without essence is still in protection domain.
