Description
Technical field
This utility model relates to a kind of selective reduction treatment of nitric acid tail gas device, is specially a kind of reducing gases and mixes with tail gas
Device.
Background technology
Having a kind of selective reduction to process tail gas in existing nitric acid tail gas denitrification apparatus, reducing gases sprays through blender
Mixing with nitric acid tail gas afterwards, enter back into reactor, but reducing gases and exhaust flow gap are very big, the flow of reducing gases is the least, therefore
General gas mixer can not make reducing gases uniformly spray distribution, and structure is more complicated, easily occurs that two kinds of gas local are mixed
Close non-uniform phenomenon, reducing gases and tail gas are efficiently utilized and has an impact, mix and uneven easily cause raw-material waste, can not get
Make full use of, the reaction effect of workshop section's reactor after impact, also environment can be caused certain pollution.
Summary of the invention
This utility model is based on above technical problem, it is provided that a kind of reducing gases and tail gas blender.This reducing gases with
Tail gas blender processing and fabricating is convenient, and mixing resistance is little, and fundamentally solves the problem that mixing is uneven, it is achieved design effect
Really, reaction is more abundant, is particularly suitable for two kinds of flows great gas of being correlated with and uniformly mixes.
The technical scheme is that
A kind of reducing gases and tail gas blender, it mainly includes reducing gases ingress pipe, arm injection apparatus, reducing gases and mixes
Gas tail closes room and constitutes；Whole blender is reequiped with one section of big pipeline, and simple in construction is easy to make.
Reducing gases ingress pipe, it is in the gas inlet section big pipeline of insertion, and the bottom of reducing gases ingress pipe is fixing welds
Being connected on big inner-walls of duct, the arm jet segment on described reducing gases ingress pipe flows to vertical with tail gas medium.
Arm injection apparatus is made up of non-font pipeline, and a vertical ingress pipe is supervisor, the right and left on ingress pipe
Being welded with some rows arm sidewards, arm tail end, is opened by arm support block welding on big inner-walls of duct on branch pipe(tube)
It is provided with several reducing gases spouts.
Using two sections of blank pipe sections alternately to install with rustless steel structured filling material layer in reducing gases and tail gas mixing chamber, packing layer depends on
Secondary dislocation is alternately；Being provided with two groups of rustless steel structured filling material layers, rustless steel structured packing is fixed by two pieces of Turbogrid plates, and Turbogrid plates weld
It is connected on 6 bracers.Described mixing chamber one end communicates with reducing gases ingress pipe, and the other end communicates with mixed gas outlet section.
Reducing gases and tail gas blender are the repacking of typical circular pipeline, first weld gripper shoe on inner-walls of duct, then will
The circular grill plate welded welds on the supporting plate, finally loads filler according to the direction of regulation, also needs welding after filler
Same gripper shoe and Turbogrid plates, another section of packing layer manufacture method is the same, and simply mutually stagger in filler filling direction.The second layer
Filler outlet section is mixed gas outlet section.
Compared with prior art, the beneficial effects of the utility model are:
(1), this tail gas and reducing gases blender have economical and practical, simple in construction, easy to make, install easily, mixed
The advantages such as, efficiency high, reduction cost savings energy consumption uniform with thing, great gas of being correlated with two kinds of flows can realize the fast of gas
Speed is sufficiently mixed, and mixed gas concentration is difficult to fluctuation, and the steady quality of mixed gas is reliable.
(2) packing layer, in reducing gases and tail gas blender misplaces alternately successively, and vertical with airflow direction, makes reduction
Gas and sweep gas mixture produce fluid cutting, shearing rotates thus mix further, and the resistance of device is the least, have reached stream
Body dispersion and well-mixed purpose, improve mixed effect.
(3), the outlet section tail gas medium of reducing gases ingress pipe flow to vertical, reducing gases ingress pipe is non-font, first passes through
Spray-hole cuts into several little fluids the reducing gases in ingress pipe and ejects, the reducing gases then ejected and following current and
The tail gas come is sufficiently mixed uniformly, does not haves the phenomenon that local reduction gas in mixing chamber is too much or very few.
Accompanying drawing illustrates:
Fig. 1 is the tangent plane structural representation of reducing gases and tail gas blender described in this utility model；
Fig. 2 is the structural representation of arm injection apparatus described in this utility model；
Fig. 3 is the structural representation of Turbogrid plates described in this utility model；
Wherein, 1 being gas inlet section, 2 be arm injection apparatus for reducing gases ingress pipe, 2-1,2-2 is reducing gases injection
Mouthful, 2-3 is that arm props up bracer, and 3 is reducing gases and tail gas mixing chamber, and 3-1 is rustless steel structured filling material layer, and 3-2 is Turbogrid plates, 3-
3 is gripper shoe, and 4 is mixed gas outlet section.
Detailed description of the invention
In order to make the summary of the invention in this utility model easily facilitate understanding, below in conjunction with the drawings and specific embodiments
