Abstract
The utility model discloses a dry process denitration spray gun nose shape shower nozzle, including the cone, the cone is close to two nozzles of one end welded connection of microcephaly, and two nozzle microcephaly ends and cone microcephaly end interconnect, nozzle and cone adopt the argon arc welding, the utility model has the advantages of it is following: through the nose shape structure of spray gun tip, the gas-solid two-phase flow that material agent and roots wind formed is divided into two here, and the material agent is divided into two parts and is blown out the spray gun and forward rush into the flue gas, and the central zone no longer appears spouting, promotes the even degree of material agent to the cover of flue gas to improve the utilization ratio of denitration agent, reduce the denitration agent and consume.
Description
Technical Field
The utility model relates to a dry process denitration technical field, concretely relates to dry process denitration spray gun nose shape shower nozzle.
Background
At present, the known dry-process denitration agent spray gun mainly comprises a steel pipe and a spray head, wherein the spray head is in a form of a straight-through type, a necking type and a convergent-divergent type, and a material agent can form a cone after leaving the spray gun in any form; as the spray gun is arranged perpendicular to the flue, the flow direction of the flue gas is necessarily perpendicular to the central line of the material cone, and as a result, the material amount of the central area of the vertical flue gas flow direction surface of the material cone is larger than that of the edge areas at two sides, namely, the over-spray occurs in the central area of the material cone, and the under-spray occurs in the edge areas.
SUMMERY OF THE UTILITY MODEL
The utility model provides a dry process denitration spray gun nose shape shower nozzle for solve the problem that proposes among the above-mentioned background art.
In order to solve the technical problem, the utility model provides a following technical scheme: dry process denitration spray gun nose shape shower nozzle, including the cone, the cone is close to the one end welded connection of microcephaly and has two nozzles, two nozzle microcephaly end and cone microcephaly end interconnect, nozzle and cone adopt argon arc welding.
As an optimal technical scheme of the utility model, the nozzle is that 60 degrees tee bend line cutting preparation and material are the tungsten steel, the cone material is 304 stainless steel, the wall thickness of cone and nozzle is 3 mm.
The utility model discloses the beneficial effect who reaches is:
through the nose shape structure of spray gun tip, the gas-solid two-phase flow that material agent and roots wind formed is divided into two here, and the material agent is divided into two parts and is blown out the spray gun and forward rush into the flue gas, and the central zone no longer appears spouting, promotes the even degree of material agent to the cover of flue gas to improve the utilization ratio of denitration agent, reduce the denitration agent and consume.
Drawings
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the invention and not to limit the invention.
In the drawings:
fig. 1 is a schematic perspective view of the present invention.
In the figure: 1. a cone; 2. and (4) a nozzle.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example (b): as shown in fig. 1, the utility model discloses dry process denitration spray gun nose shape shower nozzle, including cone 1, its characterized in that, cone 1 is close to two nozzles 2 of one end welded connection of microcephaly, and two 2 microcephaly ends of nozzle interconnect with 1 microcephaly end of cone, and nozzle 2 and cone 1 adopt argon arc welding, can make denitrifier and flue gas mix more fully, avoid local overspray, reduce material consumption, improve denitration efficiency.
Wherein, nozzle 2 is the positive tee bend line cutting preparation of 60 degrees and the material is the tungsten steel, and cone 1 material is 304 stainless steel, and cone 1 and nozzle 2's wall thickness is 3mm, promotes to mix more abundant.
Specifically, the utility model discloses during the use, at first the solid phase denitration agent blows under the effect at compressed air, is gathered together the back by cone 1, is divided into two parts through 2 diplopore structures of nose shape nozzle for the material agent can with the flue gas intensive mixing more.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
Claims (2)
1. Dry process denitration spray gun nose shape shower nozzle, including cone (1), its characterized in that, one end welded connection that cone (1) is close to the microcephaly has two nozzles (2), two nozzle (2) microcephaly end and cone (1) microcephaly end interconnect, nozzle (2) and cone (1) adopt argon arc welding.
2. The nozzle of claim 1, wherein the nozzle (2) is made of tungsten steel by 60-degree straight tee wire cutting, the cone (1) is made of 304 stainless steel, and the wall thickness of the cone (1) and the nozzle (2) is 3 mm.
