Description
Technical Field
The invention belongs to the technical field of material activation equipment, and particularly relates to a high-efficiency gas-solid heterogeneous reaction furnace.
Background
The preparation of the material related to gas-solid reaction, especially the specific surface area of the carbon material can be increased through the activation reaction of the carbon material. In the preparation of materials, the contact area of the gas phase with the solid phase and the reaction time are two conditions which are extremely important for increasing the specific surface area.
The gas-solid reaction kettle is important equipment for realizing material activation, and the gas-solid reaction kettle usually adopts a rotary furnace structure form, and the solid phase is continuously stirred in the rotating process of a furnace tube, and is contacted with the gas phase in the solid phase stirring process to realize reaction.
In actual production operation, during the rotation of the cylindrical straight tube furnace tube, the solid-phase material is basically kept at the bottom of the furnace tube under the action of gravity, and under a certain filling amount, part of the material can not be contacted with the gas phase all the time at the bottom of the furnace tube (the bottom inside the furnace tube). The contact surface of the solid phase material and the gas phase reactant is mainly a macroscopic surface of the loading amount, and the two-phase contact surface is very limited, so that in order to increase the contact area of the two-phase material in unit reaction time, a material turning plate is usually added in a rotary furnace reaction kettle, and the contact area between the solid phase and the gas phase is increased by turning over the solid phase through the material turning plate.
At present, the material turning plate applied to the rotary furnace is generally designed into a straight plate structure, namely, the straight plates are arranged along the circumferential direction of the furnace tube for turning, and when the furnace tube rotates, solid-phase materials at the bottom of the furnace tube can be lifted through the material turning plate, so that the contact surface of gas and solid phases is increased, and the reaction efficiency in unit time is improved.
However, when viewed from the cross section of the furnace tube, the material turning plate with the straight plate structure can only raise the solid-phase material to about 10 o 'clock, and then fall to 7 o' clock, and the connection is performed by using three clock points of the clock as a connection unit, so that the contact between the solid-phase material and the gas-phase material only accounts for one sixth of the connection, and the contact area between the solid-phase material and the gas-phase material is still to be further increased. If the width of the straight plate is increased, although the material lifting area can be increased by the improved mode, the width of the material turning plate is limited by the circumferential radius of the furnace tube, and the increasing effect is very limited. Especially, under the condition that the rotating linear speed of the furnace tube is low, the material turning plate adopting a straight plate type structure has the following problems: the material can slide back to the bottom of the hearth in the direction of less than 10 o' clock, the reaction contact area between the solid phase and the gas phase is reduced, and the material raising effect is worse.

The terms "connected" and "connected" used herein should be interpreted broadly, and may include, for example, a fixed connection or a detachable connection; they may be directly connected or indirectly connected through intermediate members, and specific meanings of the above terms will be understood by those skilled in the art as appropriate.
Referring to fig. 1, fig. 1 is a schematic diagram of a partial structure of a high-efficiency gas-solid heterogeneous reaction furnace according to an embodiment of the present invention.
The invention provides a high-efficiency gas-solid heterogeneous reaction furnace, which is used for realizing the mixing, contact and reaction of a gas phase and a solid phase, thereby increasing the specific surface area of the solid phase.
The mixing and contacting means that the gas phase can be mixed into the solid phase (particulate material) and contacted with the surface of the solid phase to effect a reaction with the solid phase.
The high-efficiency gas-solid heterogeneous reaction furnace provided by the invention has two structural innovation points: 1. a cylindrical reaction furnace tube 1 is adopted, a spiral helical blade 2 is arranged in the reaction furnace tube 1, the stirring of a solid phase is realized through the helical blade 2, the effect of material raising is achieved, and the helical blade is used for increasing the contact area of a gas phase and the solid phase; 2. the structure of the inner edge structure 3 of the helical blade 2 is optimized, so that a closed structure is formed at the inner edge part of the helical blade 2 (the gas phase is prevented from directly flowing through the inner edge structure 3 of the helical blade 2), the gas phase can flow spirally along the helical blade 2, and the residence reaction time of the gas phase in the reaction furnace tube 1 is prolonged.
In one embodiment of the present invention, the high efficiency gas-solid heterogeneous reaction furnace provided by the present invention comprises the following composition structure:
1. the reaction furnace tube 1 keeps the rotary motion state in the working process.
The reaction furnace tube 1 is a structure for realizing gas-phase and solid-phase reactions for a high-efficiency gas-solid heterogeneous reaction furnace, the reaction furnace tube 1 is a tubular structure, which can be a circular tube structure, and can also be other structures, such as a regular polygonal prism (tubular structure), and the reaction furnace tube 1 is made of a metal material, preferably a stainless steel plate.
The internal space of the reaction furnace tube 1 is used for loading the solid phase, the reaction furnace tube 1 keeps an allowable rotation state in the working process, and the solid phase is stirred in the reaction furnace tube 1 along with the rotation of the reaction furnace tube 1, so that the solid phase is raised, and the purpose of increasing the contact area with the gas phase is achieved.
2. And the helical blade 2 is arranged in the reaction furnace tube 1 and is arranged along the axial direction of the reaction furnace tube 1.
If the solid phase is pumped in the reaction furnace tube 1 by the rotation of the reaction furnace tube 1, the effect is to be further improved, therefore, the invention provides the helical blade 2.
The helical blade 2 is a helical plate structure having a certain width. More specifically, a ring (or a circular plate) is cut off along the radial direction, then both cut ends are stretched along the axial direction to form a spiral blade unit, and a plurality of spiral blade units are connected end to end in sequence to form a complete spiral blade 2 (the spiral blade 2 is composed of at least one spiral blade unit, preferably three spiral blade units).
In the above-described structural design, if the helical blade 2 (helical blade unit) is formed by cutting and stretching a circular ring, the axial projection of the helical blade 2 is a circular ring structure. The gas phase enters from one end of the reaction furnace tube 1 and is output from the other end of the reaction furnace tube 1, and a majority of the gas phase flows linearly along the axial direction of the helical blade 2, so that the contact time with the solid phase is short. In order to prevent the gas phase from flowing along the axial straight line of the helical blade 2, the invention optimizes the structure of the helical blade 2: the outer edge of the helical blade 2 is connected with the inner side wall of the reaction furnace tube 1, the inner edge of the helical blade 2 is provided with an inner edge structure 3, and the projection of the inner edge structure 3 can cover the projection middle part of the helical blade 2 in the axial direction of the reaction furnace tube 1 (if the inner edge structure 3 is not arranged, the projection middle part of the helical blade 2 is blank, so that the gas phase directly passes through the helical blade 2 along a straight path, and the problem of short retention time of the gas phase in the reaction furnace tube 1 is caused). In popular terms, the method is as follows: after the inner edge structure 3 is arranged on the inner edge part of the helical blade 2, the projection of the inner edge structure 3 in the axial direction of the reaction furnace tube 1 can cover the blank part in the middle of the projection of the helical blade 2 (if the inner edge structure 3 is not arranged, the axial projection of the helical blade 2 is circular, and the middle part is blank). Because the inner edge structure 3 is arranged, a closed structure is formed in the middle of the helical blade 2 through the inner edge structure 3, the gas phase can be prevented from directly flowing through the middle of the helical blade 2 and flowing along the helical path along the helical blade 2, so that the retention time of the gas phase in the reaction furnace tube 1 can be increased, and the contact area between the gas phase and the solid phase can be increased.
In a preferred embodiment of the present invention, the reaction furnace tube 1 is a circular tube structure, which not only facilitates the production and manufacture of the reaction furnace tube 1, but also facilitates the design and installation of the helical blades 2.
In a preferred embodiment of the present invention, the helical blade 2 is designed in a structure with an axial projection as a circular ring, that is: the width of the helical blades 2 is uniform. Meanwhile, the invention also limits the consistent spiral angle of the spiral blades 2 and the consistent pitch of the spiral blades 2, so that the solid phase can be uniformly stirred and raised in the reaction furnace tube 1.
The reaction furnace tube 1 is preferably made of stainless steel, and the helical blade 2 is made of the same material as the reaction furnace tube 1. Helical blade 2 can be formed by a plurality of helical blade units end to end connection concatenation in proper order, also can adopt a whole sheet of rectangle panel to form the breach through shearing at the edge of inboard and buckle and form.
Further, in the present invention, the surface of the helical blade 2 is a smooth planar structure or a curved surface structure.
The helical blade 2 has two structural forms: 1. the helical blade 2 is in a circular ring structure along the axial projection; 2. the helical blades 2 win a circular structure along the axial direction.
For the first structure, the projection width of the helical blade 2 in the axial direction of the reaction furnace tube 1 is smaller than the radius of the reaction furnace tube 1, an inner edge structure 3 is arranged through the helical blade 2, the inner edge structure 3 is a cylinder (the axial length of the inner edge structure 3 is greater than the axial overall length of the helical blade 2), the inner edge structure 3 is a structure with two closed ends, the inner edge structure 3 is coaxially arranged with the reaction furnace tube 1, the inner edge of the helical blade 2 is fixedly connected with the outer side surface of the inner edge structure 3, and the helical blade 2 is arranged between the reaction furnace tube 1 and the inner edge structure 3 and is formed with a helical mixing channel for gas phase and solid phase reactions.
As can be seen from the above, the inner edge structure 3 is a cylindrical structure, and the inner edge structure 3 may be a solid structure or a hollow structure. When the inner rim structure 3 is a solid structure, the inner rim structure 3 may be integrally formed of a rigid plastic. When the inner edge structure 3 is a hollow structure, the inner edge structure 3 is a cylindrical structure, and end caps are disposed at two ends of the inner edge structure 3, in this embodiment, the inner edge structure 3 is made of a metal material. The present invention is preferably embodied such that the inner edge structure 3 is a hollow structure.
In order to further increase the solid-phase material raising effect of the invention, the material raising plates for raising the solid phase are arranged in the gaps of the helical blades 2 and on the inner side surface of the reaction furnace tube 1, and the material raising plates can be of a flat plate structure, an L-shaped structure or any other structure capable of realizing solid-phase material raising. Specifically, the number of the lifting plates is determined according to the inner diameter of the reaction furnace tube 1, and the lifting plates should be sized to ensure that the solid phase does not cross the inner edge structure 3 (the central tubular structure arranged at the inner edge of the helical blade 2) after being lifted.
Specifically, the helical blade 2 is a metal integral structure; the inner edge structure 3 is a metal structure. The helical blade 2 and the inner edge structure 3 are made of the same metal material, preferably stainless steel.
The invention also provides a high-efficiency gas-solid heterogeneous reaction furnace, wherein the reaction furnace tube 1 which keeps a rotary motion state in the working process and the helical blade 2 which is arranged in the reaction furnace tube 1 and arranged along the axial direction of the reaction furnace tube 1 are arranged, the outer edge of the helical blade 2 is connected with the inner side wall of the reaction furnace tube 1, the inner edge of the helical blade 2 is provided with an inner edge structure 3, and the inner edge structure 3 is arranged in the gap of the helical blade 2 and is used for sealing the inner edge of the helical blade 2 and enabling the helical blade 2 to form a sealed helical mixing channel which is used for gas phase and solid phase reactions in the reaction furnace tube 1. The high-efficient heterogeneous reacting furnace of gas-solid that this embodiment provided all keeps unanimous with the structural style of foretell heterogeneous reacting furnace of gas-solid tubular column 1 and helical blade 2 in the reacting furnace, and the difference is: in this embodiment, a new design concept is proposed for the inner edge structure 3, that is, the inner edge structure 3 is disposed between the helical blades 2 and is connected with the inner side edges of the helical blades 2 in an airtight manner, so that the reaction furnace tube 1, the helical blades 2 and the inner edge structure 3 form a closed helical channel, so that the gas phase can be transported only in the helical channel.
Specifically, the reaction furnace tube 1 is of a circular tube structure, the width of the helical blades 2 is consistent, the helical angle of the helical blades 2 is consistent, and the pitch of the helical blades 2 is consistent. The inner edge structure 3 is a spiral vertical plate structure.
Further, the helical blade 2 is of a metal integral structure; the inner edge structure 3 is a metal integral structure; the inner edge structure 3 is welded with the helical blade 2.
