Abstract
The utility model discloses a denitration rectifier, comprising at least two layers of airflow passage components that are superposed with each other; the airflow passage component consists of transverse plates that are arranged in parallel and vertical plates that are arranged between the transverse plates in parallel; two adjacent transverse plates and two adjacent vertical plates form a square hole by which the airflow passes; the two adjacent layers of airflow passage components are staggered and superposed so that one square hole of the upper layer of airflow passage component is simultaneously communicated with the four square holes of the lower layer of airflow passage. One of the airflow square hole of the upper layer of airflow passage component of the denitration rectifier is simultaneously communicated with four airflow square holes of the lower layer of airflow passage, thus playing the role of sufficiently mixing the airflow; therefore, the area of the square hole of the airflow passage component can be larger and the quantity of the transverse plates and the vertical plates used for manufacturing the airflow passage components can be less, thus saving the manufacturing material; the workload of welding the transverse plates and the vertical plates is less, the clearance between the transverse plate and the vertical plate is larger, the welding difficulty is lower, and the manufacturing efficiency of the denitration rectifier can be improved greatly.
Description
Technical field
The utility model relates to a kind of smoke eliminator, the rectifier in particularly a kind of flue gas denitration reactor.
Background technology
In the running of denitrification apparatus, denitration efficiency is relevant with several factors.Wherein the be evenly distributed problem of denitrification reducing agent in flue gas is the problem that we are concerned about most, and under high temperature, high grey operating mode, the gaseous mixture of ammonia and flue gas reaches the denitration purpose by the effect of catalyst in the reactor.Ammonia and flue gas mixing uniformity directly influence the denitration rate.The setting of rectifier is exactly that flue gas and ammonia gas mixture body were more evenly distributed before entering catalyst.
Existing rectifier is that the square tube of 80x80x500 is the 70 square tube groups that equidistantly are welded by spacing, and rectifier is installed in the reactor inlet section, and flue gas and ash content enter reactor in 80x80 rectifier side pore.
The problem that existing rectifier exists is: the distance between single square tube is less, and the square tube quantity in the square tube group is bigger, so its welding job amount is bigger, and the spacing between square tube is too little simultaneously, and the welding difficulty is bigger, thereby existing rectifier extremely is inconvenient to make and install.
Therefore need improve denitration rectifier structure of the prior art, make it easy to make, to improve make efficiency and to reduce manufacture difficulty.
Summary of the invention
In view of this, the purpose of this utility model provides a kind of denitration rectifier, and it has makes characteristics such as the little and manufacture difficulty of workload is low, the make efficiency of raising denitration rectifier that can be very big.
The utility model denitration rectifier, comprise the gas channel assembly of two superimposed setting at least, described gas channel assembly is made up of parallel transverse slat that is set up in parallel and the parallel riser that is set up in parallel between transverse slat, adjacent two transverse slats and two risers are formed the square hole of airflow passes, and the dislocation of adjacent two layers gas channel assembly stacks a square hole that makes upper strata gas channel assembly and is communicated with four square holes of lower floor gas channel simultaneously.
Further, the described upper strata gas channel assembly cross center of intersecting with its transverse slat and the riser mode that is arranged on lower floor gas channel assembly square hole center overlays on lower floor's gas channel assembly;
Further, described gas channel assembly is two-layer;
Further, the cross section of described square hole is a square;
Further, described square hole cross section size is 75mm * 75mm～150mm * 150mm, and square hole length is 250mm.
The beneficial effects of the utility model: the utility model denitration rectifier, form by the gas channel assembly that dislocation stacks, air-flow square hole that can make the upper strata gas channel is communicated with four air-flow square holes of lower floor gas channel simultaneously, thereby can play the effect of abundant mixed airflow, therefore the square hole area of this gas channel assembly can be provided with greatlyyer, transverse slat and riser negligible amounts when making the gas channel assembly, can save the making material, the workload of welding transverse slat and riser is less, the gap is bigger between transverse slat and riser, the welding difficulty is lower, the make efficiency of raising denitration rectifier that can be very big.

The specific embodiment
Accompanying drawing is the utility model denitration rectifier structure schematic diagram.
As shown in the figure, the utility model denitration rectifier, comprise the gas channel assembly that two superimposed is provided with, described gas channel assembly is made up of parallel transverse slat that is set up in parallel 1 and the parallel riser 2 that is set up in parallel between transverse slat 1, adjacent two transverse slats 1 and two risers 2 are formed the square hole 3 of airflow passes, and the dislocation of adjacent two layers gas channel assembly stacks a square hole that makes upper strata gas channel assembly and is communicated with four square holes of lower floor gas channel simultaneously.The number of plies of gas channel assembly can be provided with according to actual needs, stack more than two-layer all and can realize the present invention, the gas channel assembly that dislocation stacks, air-flow square hole that can make the upper strata gas channel is communicated with four air-flow square holes of lower floor gas channel simultaneously, thereby can play the effect of abundant mixed airflow, therefore the square hole area of this gas channel assembly can be provided with greatlyyer, transverse slat and riser negligible amounts when making the gas channel assembly, can save the making material, the workload of welding transverse slat and riser is less, the gap is bigger between transverse slat and riser, and the welding difficulty is lower, the make efficiency of raising denitration rectifier that can be very big.
In the present embodiment, the mode that the cross center that described upper strata gas channel assembly intersects with its transverse slat and riser is arranged on lower floor gas channel assembly square hole center overlays on lower floor's gas channel assembly, can make that the air-flow in each square hole flows in four square holes of lower floor's gas channel assembly uniformly in the gas channel assembly of upper strata, can reach best mixing current-sharing effect.
In the present embodiment, the cross section of described square hole is square, and is simple in structure, helps improving gas channel establishment of component efficient, can also be set to rectangle or parallelogram etc. certainly in concrete enforcement.
In the present embodiment, described square hole cross section size is 150mm * 150mm, and square hole length is 250mm; Certainly square hole cross section size all has rectification effect preferably in concrete the enforcement between 150mm * 150mm～300mm * 300mm.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
