Description

Nozzle and gasifier having the same

technical field

The present invention relates to the field of chemical industry, in particular, to a nozzle and a gasifier with the nozzle.

Background technique

CN1903998B discloses a gasifier injector comprising a two-stage mud flow separator and an injector panel integrated with a cooling system. The first-stage separator separates the main mud flow into multiple secondary mud flows, each of which is separated into multiple third-stage mud flows through the second-stage separator, and the third-stage mud flow is injected through the mud flow. The tubes are injected into the gasification chamber as a high pressure mud flow. The reactants are impinged on each high pressure mud stream under high pressure in the form of an annular shaped spray through a plurality of annular impingement holes integrated in the faceplate of the injector.

The vaporizer injector has the following problems:

(1) In the process of material conveying from top to bottom, due to the influence of the gravity of the material itself and the "side wall effect" of pipeline conveying, the material often does not pass through the center of the conveying pipe, but passes through one side of the conveying pipe. As a result, the first-stage fluid separator 42 and the second-stage fluid separator 50 will lose the material distribution function, and the material will only flow from one or a few of the secondary chambers 46 and one or a few of the mud injection pipes 26. A flow through, the material distribution is extremely uneven.

(2) There are many dead corners between the multiple secondary chambers 46 , that is, there are many dead corners on the bottom wall of the main chamber 38 , which is very easy to block the passage when the material concentration is high.

The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to explain the present invention, but should not be construed as a limitation of the present invention.

The nozzle 10 according to the embodiment of the present invention will be described below with reference to the accompanying drawings. As shown in FIGS. 1-9 , the nozzle 10 according to the embodiment of the present invention includes a body 110 and a first material distribution member 120 .

The body 110 has an accommodating cavity 111 , and a feeding port 112 is provided on the top wall of the accommodating cavity 111 . The first material distribution member 120 is disposed in the accommodating cavity 111 , and a plurality of first material distribution channels 121 penetrating the first material distribution member 120 in the up-down direction are provided on the first material distribution member 120 . Wherein, a portion of the upper surface 122 of the first material distribution member 120 located between the adjacent plurality of first material distribution channels 121 is provided with a first material distribution portion 130, and the first material distribution portion 130 has a plurality of side surfaces 131, The lower edges of the plurality of side surfaces 131 are adjacent to the edges of the corresponding adjacent plurality of first material distribution channels 121 in a one-to-one correspondence.

The materials entering the accommodating cavity 111 through the feeding port 112 are distributed through the first material distribution part 130 , so that the materials can evenly enter the adjacent plurality of first material distribution channels 121 arranged around the first material distribution part 130 . Inside. Because the present invention provides the first material distribution part 130 between the adjacent plurality of first material distribution channels 121, instead of just disposing the fluid separator in the center of the chamber as in the patent application with the publication number of CN1903998B, it does not This will cause the first material distribution part 130 to lose the material distribution function due to the influence of the material's own gravity and the "side wall effect" of pipeline transportation.

The nozzle 10 according to the embodiment of the present invention is provided with the first material distribution part 130 on the part of the upper surface 122 of the first material distribution part 120 located between the adjacent plurality of first material distribution channels 121 , so that the first material distribution part 130 can be prevented. The first material distribution part 130 loses the material distribution function due to the influence of the material's own gravity and the "side wall effect" of pipeline transportation. In this way, the material entering the accommodating cavity 111 can be evenly distributed into the plurality of first material distribution channels 121 by using the first material distribution part 130 .

Moreover, since the lower edges of the plurality of side surfaces 131 of the first material distribution part 130 are adjacent to the edges of the corresponding adjacent plurality of first material distribution channels 121 in a one-to-one correspondence, it is possible to greatly reduce the size of the first material distribution part 120 . The dead space on the upper surface can prevent the material (especially when the material concentration is high) from clogging the first material distribution channel 121, that is, material accumulation can be prevented.

In addition, by arranging a plurality of first material distribution channels 121 on the first material distribution member 120, the nozzle 10 can be used to transport high-pressure ultra-dense phase materials (such as gasification raw materials), and the materials enter the plurality of first material distribution materials after material distribution. In the material distribution channel 121 , not only can the material handling capacity be increased, but also the load of the nozzle 10 can be reduced.

As shown in FIG. 1 and FIG. 2 , preferably, the nozzle 10 may further include a feeding pipe 151 , and the feeding pipe 151 may be connected with the feeding port 112 , thereby making the structure of the nozzle 10 more reasonable.

The first material distribution member 120 is disposed in the accommodating cavity 111 , and a plurality of first material distribution channels 121 penetrating the first material distribution member 120 in the up-down direction are provided on the first material distribution member 120 . Wherein, a portion of the upper surface 122 of the first material distribution member 120 located between the adjacent plurality of first material distribution channels 121 is provided with a first material distribution portion 130, and the first material distribution portion 130 has a plurality of side surfaces 131, The lower edges of the plurality of side surfaces 131 are adjacent to the edges of the corresponding adjacent plurality of first material distribution channels 121 in a one-to-one correspondence.

Preferably, one of the plurality of side surfaces 131 may be in contact with the peripheral wall surface 1111 of the accommodating cavity 111 . In this way, the dead angle between the first material distribution member 120 and the peripheral wall surface 1111 of the accommodating cavity 111 can be completely eliminated, that is, the dead angle between the first material distribution member 120 and the main body 110 can be completely eliminated, thereby preventing material (especially When the material concentration is high), it is accumulated (accumulated) between the first material distribution member 120 and the peripheral wall surface 1111 of the accommodating cavity 111 .

Since the portion of the upper surface 122 of the first material distribution member 120 located between the adjacent plurality of first material distribution channels 121 is provided with the first material distribution portion 130 , the adjacent plurality of first material distribution channels 121 surround the first material distribution channel 121 . A feeding part 130 is provided. There may be multiple portions of the upper surface 122 of the first material distribution member 120 between the adjacent plurality of first material distribution channels 121 , that is, a plurality of first material distribution members 120 may be provided on the upper surface 122 of the first material distribution member 120 . Distributing section 130.

"The lower edges of the plurality of side surfaces 131 are adjacent to the edges of the corresponding adjacent plurality of first material distribution channels 121 in a one-to-one correspondence" means that the lower edges of the plurality of side surfaces 131 of the first material distribution portion 130 are adjacent to each other in a one-to-one correspondence The edges of a plurality of adjacent first material distribution channels 121 disposed around the first material distribution part 130 . In other words, the plurality of adjacent first material distribution channels 121 disposed around the first material distribution portion 130 are the adjacent plurality of first material distribution channels 121 corresponding to the first material distribution portion 130 .

Preferably, the peripheral surface of the first material distribution member 120 is in contact with the peripheral wall surface 1111 of the accommodating cavity 111 . That is to say, there is no gap between the peripheral surface of the first material distribution member 120 and the peripheral wall surface 1111 of the accommodating cavity 111 .

As shown in FIG. 2, in one embodiment of the present invention, one of the plurality of first distribution channels 121 may be the first central distribution channel 121a, and the rest of the plurality of first distribution channels 121 may be The first outer peripheral material distribution channel 121b, a plurality of first outer peripheral material distribution channels 121b may be disposed along the circumferential direction of the first material distribution member 120 around the first central material distribution channel 121a. Wherein, the circumferential direction of the first material distribution member 120 may be the same as the circumferential direction of the main body 110 .

A first material distribution is provided on a part of the upper surface 122 of the first material distribution member 120 located between the first central material distribution channel 121a, the peripheral wall surface 1111 of the accommodating cavity 111 and the two adjacent first outer peripheral material distribution channels 121b. Section 130. Therefore, the number of the first distribution parts 130 can be equal to the number of the first peripheral distribution channels 121b.

Moreover, unlike the patent application with publication number CN1903998B, the patent application with publication number CN104804772A and the patent application with publication number US4194500A, the nozzle 10 of the present invention is not in the middle (center) of the upper surface 122 of the first material distribution member 120 The first distributing part 130 is disposed at the position), but a plurality of first distributing parts 120 are disposed on a portion of the upper surface 122 of the first distributing part 120 surrounding the middle thereof. Preferably, the middle portion of the upper surface 122 of the first material distribution member 120 may be provided with a first central material distribution channel 121a.

The first distribution part 130 has a first side to a fourth side 131c, the lower edge of the first side can be adjacent to the peripheral wall surface 1111 of the accommodating cavity 111, and the lower edge of the second side 131a can be adjacent to the first central distribution channel 121a. The edge, the third side surface 131b and the fourth side surface 131c may be adjacent to the corresponding (the "corresponding" meaning is as described above, and will not be repeated here) in a one-to-one correspondence with the edges of the adjacent two first peripheral distribution channels 121b . In other words, the third side surface 131b may be adjacent to the edge of one of the two adjacent first peripheral distribution channels 121b, and the fourth side surface 131c may be adjacent to the edge of the other of the two adjacent first peripheral distribution channels 121b.

This can further prevent the first distributing part 130 from losing its distributive effect due to the gravity of the material itself and the "side wall effect" of pipeline transportation, so that the material entering the accommodating cavity 111 can be more evenly distributed to multiple first distributing parts. Inside a material distribution channel 121 .

Preferably, the lower edge of the first side surface may be in contact with the peripheral wall surface 1111 of the accommodating cavity 111 , the lower edge of the second side surface 131 a may overlap with a part of the edge of the first central distribution channel 121 a , and the lower edge of the third side surface 131 b The lower edge of the fourth side surface 131c may be in a one-to-one correspondence with a part of the edge of the adjacent two first peripheral distribution channels 121b. Thereby, the dead space on the upper surface of the first material distribution member 120 can be further reduced, so that the first material distribution channel 121 can be further prevented from being blocked by the material (especially when the material concentration is high), that is, the material accumulation can be further prevented.

More preferably, the first side surface is in contact with the peripheral wall surface 1111 of the accommodating cavity 111 . Thereby, the dead angle on the upper surface of the first material distribution member 120 can be completely eliminated, thereby completely preventing the material (especially when the material concentration is high) from clogging the first material distribution channel 121, that is, material accumulation can be completely avoided.

The second side 131a and the peripheral wall of the first central distribution channel 121a are located on the same peripheral surface, and the third side 131b and the fourth side 131c are located on the peripheral walls of the adjacent two adjacent first peripheral distribution channels 121b in a one-to-one correspondence. on the same circumference. That is to say, the third side surface 131b and the peripheral wall surface of one of the two adjacent first peripheral distribution channels 121b are located on the same peripheral surface, and the fourth side surface 131c is located on the same peripheral surface as the two adjacent first peripheral distribution channels 121b. The other of the walls lies on the same circumference.

Therefore, the second side surface 131a, the third side surface 131b and the fourth side surface 131c can better guide the material into the corresponding first material distribution channel 121, so that the material after passing through the first material distribution part 130 can be dispersed (distributed). The materials enter into the first central distribution channel 121 a and the adjacent two adjacent first peripheral distribution channels 121 b corresponding to the first distribution portion 130 more easily and uniformly.

In other words, the cross section of the first central distribution channel 121a is circular, and the cross section of each of the first peripheral distribution channels 121b is circular. That is, the first central distribution channel 121a is a circular hole, and each of the first outer peripheral distribution channels 121b is a circular hole.

The distance from the central axis of the first central distribution channel 121a to any point on the second side surface 131a is equal to the radius of the first central distribution channel 121a, and the center axis of one of the adjacent two first peripheral distribution channels 121b reaches The distance from any point on the third side surface 131b is equal to the radius of the one of the two adjacent first peripheral distribution channels 121b, and the center axis of the other of the adjacent two first peripheral distribution channels 121b to the fourth The distance from any point on the side surface 131c is equal to the radius of the other one of the two adjacent first peripheral distribution channels 121b.

As shown in FIG. 2 and FIG. 3 , the area of the cross section of the first distribution part 130 may decrease from bottom to top. Therefore, the material distribution effect of the first material distribution part 130 can be improved, that is, the effect of the first material distribution part 130 to disperse materials can be improved. Preferably, the area of the cross section of the first material distributing part 130 can be reduced from bottom to top, thereby further improving the material distributing effect of the first material distributing part 130 .

Further preferably, the upper end of the first side surface, the upper end of the second side surface 131a, the upper end of the third side surface 131b and the upper end of the fourth side surface 131c may intersect at one point. In other words, the first distribution part 130 may be tapered. Thereby, the material distribution effect of the first material distribution part 130 can be further improved.

As shown in FIG. 2 and FIG. 3 , the portion of the accommodating cavity 111 located between the feed port 112 and the first material distribution member 120 may be the first material distribution chamber 113 , that is, the first material distribution member 120 is located in the first material distribution member 120 . below chamber 113. The area of the cross section of the first material distribution chamber 113 is larger than the area of the cross section of the feed port 112 . Therefore, when the material (raw material) enters the first material distribution chamber 113 from the feed port 112 , the concentration of the material can be reduced, thereby preventing the material from clogging the first material distribution channel 121 .

In a specific example of the present invention, as shown in FIG. 2 , a first dispersion medium inlet 114 may be provided on the peripheral wall surface 1131 of the first material distribution chamber 113 , that is, the peripheral wall surface 1111 of the accommodating cavity 111 is connected with the first material distribution medium. An opposite portion of the chamber 113 may be provided with a first dispersion medium inlet 114 . In this way, the dispersion medium can be transported into the first material distribution chamber 113 through the first dispersion medium inlet 114, so that the material located in the first material distribution chamber 113 can be impacted (one impact) by the dispersion medium, so that the material in the first material distribution chamber 113 can be impacted by means of impact. The material in the material distribution chamber 113 is divided, so that the material is dispersed more evenly.

The dispersion medium entering into the first material distribution chamber 113 through the first dispersion medium inlet 114 may be selected from at least one of nitrogen, carbon dioxide and hydrogen.

As shown in FIG. 2 , there may be a plurality of first dispersion medium inlets 114 , and the plurality of first dispersion medium inlets 114 may be provided on the peripheral wall surface 1131 of the first material distribution chamber 113 along the circumferential direction of the first material distribution chamber 113 . Thereby, the materials in the first material distribution chamber 113 can be impacted more uniformly and fully, so that the materials are dispersed more uniformly.

Preferably, the included angle between each first dispersion medium inlet 114 and the feed port 112 may be greater than 0 degrees and less than 180 degrees. That is, the included angle between the central axis of each first dispersion medium inlet 114 and the central axis of the feed port 112 may be greater than 0 degrees and less than 180 degrees.

More preferably, the included angle between each first dispersion medium inlet 114 and the feed port 112 may be greater than 30 degrees and less than 60 degrees. Therefore, the impact effect of the dispersion medium on the material can be improved, so that the material can be dispersed more uniformly.

As shown in FIG. 2 , FIG. 4 and FIG. 8 , the first material distribution member 120 may have a dispersion medium cavity 123 , and a second dispersion medium inlet 125 may be provided on the peripheral wall surface 1232 of the dispersion medium cavity 123 .

Wherein, the portion of the accommodating cavity 111 located below the first material distribution member 120 may include a second material distribution chamber 115 , and the second material distribution chamber 115 may communicate with each of the first material distribution channel 121 and the dispersion medium channel 124 .

Therefore, the dispersion medium can be transported into the second material distribution chamber 115 through the second dispersion medium inlet 125 and the dispersion medium channel 124, so that the material in the second material distribution chamber 115 can be hit (secondary impact) by the dispersion medium, so as to The materials in the second material distribution chamber 115 are distributed by means of impact, so that the materials are dispersed more uniformly. Wherein, the material leaving the first material distribution channel 121 enters the second material distribution chamber 115 .

The dispersion medium entering into the second material distribution chamber 115 through the second dispersion medium inlet 125 and the dispersion medium channel 124 may be selected from at least one of nitrogen, carbon dioxide and hydrogen.

As shown in FIGS. 4 and 8 , there may be multiple dispersion medium channels 124 , and the multiple dispersion medium channels 124 may constitute multiple dispersion medium channel groups, and each dispersion medium channel group may include at least two dispersion medium channels 124 . Wherein, at least two dispersion medium channels 124 of each of the dispersion medium channel groups may be disposed around the plurality of first material distribution channels 121 in a one-to-one correspondence.

That is, the number of the dispersion medium channel group may be equal to the number of the first distribution channels 121 , and at least two dispersion medium channels 124 of one dispersion medium channel group may be arranged around one first distribution channel 121 . Thereby, the materials in the second material distribution chamber 115 can be impacted more uniformly and fully, so that the materials are dispersed more uniformly.
