Description

Technical Field

[0001] The invention relates to the field of kilns, and in particular to a ceramic kiln for reforming mineral substances to produce hydrogen and burn. Background Art

[0002] With the development of hydrogen energy, hydrogen is gradually used in the field of ceramic kilns. In ceramic kilns using hydrogen energy, hydrogen and other gases are supplied by hydrogen production equipment in the form of mineral hydrogen production, and then reformed, separated and filtered out unnecessary gases as needed. Later, they are mixed with natural gas and supplied to the burner of the kiln for ignition, thereby generating flames to heat up the inside of the kiln to sinter the ceramics. Under the appropriate hydrogen ratio, the calorific value of the mixture can be increased to obtain a higher sintering temperature.

[0028] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] Examples, such as Figure 1-Figure 7 As shown: The present invention provides a ceramic kiln for reforming minerals to produce hydrogen and combustion, the structure of which includes a kiln body 1 and a hydrogen production device, the hydrogen production device including a gas preparation device 2, a gas-water separation tank 3 and a finishing tank 4, the gas preparation device 2 for the reaction of minerals and gasifiers, as known to those skilled in the art, the mineral includes coal, the gasifier includes water vapor, the coal and the water vapor generate hydrogen at high temperature, the gas and liquid are separated by the gas-water separation tank 3, and then the impurities are sorted and separated by the finishing tank 4, such as using the difference in permeability of carbon monoxide and hydrogen on different types of membranes, separating carbon monoxide and hydrogen through polymer membranes, ceramic membranes, etc., and outputting hydrogen separately, the kiln body 1 is connected to a supply pipeline for providing fuel gas for the kiln body 1, the supply pipeline includes a main gas pipe 5 and a hydrogen pipe 6, the main gas pipe 5 supplies natural gas, and the hydrogen pipe 6 is connected to the hydrogen production device to output hydrogen, and the two are mixed according to a ratio known to those skilled in the art;

[0030] A combustion assembly 7 is provided in the kiln body 1 and connected to the supply pipeline. The combustion assembly 7 includes a burner pipe 71 and a fire pressure ring 72. A support beam 1c is provided on the outside of the kiln body 1. The burner pipe 71 is fixedly connected to the support beam 1c through a bracket. A three-way joint is provided at the bottom of the burner pipe 71. The two interfaces of the three-way joint are respectively connected to the main gas pipe 5 and the hydrogen pipe 6 through a diversion gas pipe 74. The burner pipe 71 is wrapped with an outer enclosure 73 on the outside. A side platform 1a is horizontally provided in the kiln body 1 and a fire port 1b is provided on the side platform 1a. The outer enclosure 73 is nested and installed in the fire port 1b. The outer enclosure 73 is made of the same heat-insulating material as the inner wall of the kiln body 1.

[0031] In this embodiment, an automatic ignition is adopted, starting from three directions. First, a mobile assembly 75 is movably mounted on the outer package 73. The states of the mobile assembly 75 include a basic state and an ignition state. In the basic state, the mobile assembly 75 is at a lower horizontal height. The mobile assembly 75 moves upward from the basic state to enter the ignition state. The fire-pressing ring 72 for stabilizing the flame is placed on the top of the burner tube 71 and the mobile assembly 75 in the basic state, and the fire-pressing ring 72 moves with the lifting and lowering of the mobile assembly 75, thereby ensuring the integrity of the fire-pressing ring 72.

[0032] Then: the moving assembly 75 includes an outer bracket 752 and an ignition assembly 77 is arranged on the outer bracket 752. The ignition assembly 77 has an ignition probe 771 for generating an arc. The ignition assembly 77 is located outside the kiln body 1 in the basic state of the moving assembly 75, so that the ignition assembly 77 is outside the kiln body 1 when not in use. In addition, when the moving assembly 75 is in the basic state, the movement path of the moving assembly 75 above the ignition assembly 77 on the outer enclosure 73 is closed, and the side surface of the outer enclosure 73 is nested with the burner 1b to form a closed state.

[0033] Finally: the ignition probe 771 points to the opening area of ​​the burner tube 71 when the moving component 75 is in the ignition state, so that the ignition probe 771 also enters the working state to ignite the gas ejected from the burner tube 71, so that the outside of the burner tube 71 has enough outer body 73 to directly wrap it. On the basis of stable thermal insulation quality, the ignition probe 771 can cross the outer body 73 on the outside of the burner tube 71 to the top of the burner tube 71 without interfering with the outer body 73. It can be seen that the ignition probe 771 is connected to the external control system and power supply equipment, so as to control the ignition probe 771 to ignite.

[0034] Specifically, the moving assembly 75 includes a base 753 driven by a cylinder-type moving actuator 76 to move up and down. The cylinder-type moving actuator 76 is installed on the support beam 1c and adopts a guide rod cylinder with its own guide structure. A plurality of outer brackets 752 are provided and installed on the base 753. A movable groove 73a is provided on the outer enclosure 73 along the movement path of the ignition assembly 77. The sides of the movable groove 73a are formed by the outer enclosure 73. The moving assembly 75 in the basic state is nested with the outer enclosure 73 to form a closure to the movable groove 73a, so that the outer enclosure 73 above the ignition assembly 77 is in a closed state. In addition, a material rack 751 is provided on the top of the outer bracket 752. The material rack 751 adopts the same heat-insulating material as the inner wall of the kiln body 1. The material rack 751 of the moving assembly 75 in the basic state is nested with the outer enclosure 73 to form a closure, and the fire-pressing ring 72 is placed on the material rack 751.

[0035] In this embodiment, there are three outer brackets 752 and material racks 751. A synchronization ring 754 is extended laterally from the top of the material rack 751 to connect the three material racks 751. The material rack 751 cooperates with the base 753 to ensure the stability of the overall frame of the moving assembly 75. The fire suppression ring 72 is placed on the synchronization ring 754 formed by the material rack 751.

[0036] At the same time, the ignition assembly 77 also includes a mounting body 773 and a synchronous transposition frame group 775 installed in the mounting body 773, and also includes a temperature probe 772 connected to the control system. The mounting body 773 is in a shell shape. The temperature probe 772 is close to the opening area of ​​the burner tube 71 in the ignition state of the moving assembly 75. The projection of the ignition probe 771 on the horizontal plane is located within the projection range of the mounting body 773 and is in a storage shape. Therefore, the ignition probe 771 is stored in the mounting body 773 or between the mounting body 773 and the outer bracket 752, and the ignition probe 771 is linked with the synchronous transposition frame group 775. The moving assembly 75 moves to the ignition state so that the synchronous transposition frame group 775 drives the ignition probe 771 to extend. The extended ignition probe 771 is located above the burner tube 71 and its projection on the horizontal plane interferes with the inner side of the burner tube 71, thereby ensuring that the arc emitted by the ignition probe 771 can contact the gas ejected from the burner tube 71.

[0037] To this end, a rotating shaft 774 is installed at the bottom of the ignition probe 771, and a stabilizing shaft seat 773a is provided in the mounting body 773. The rotating shaft 774 is installed in the stabilizing shaft seat 773a and retains the freedom of rotation around the axis. The synchronous transposition frame group 775 includes a frame body, and a guiding portion 773b for guiding is provided in the mounting body 773. The frame body and the guide portion 773b are vertically slidably matched. The frame body extends to the outside of the mounting body 773 and is provided with a contact plate 776. The contact plate 776 contacts the outer body 73 during the rising process of the moving component 75, thereby driving the frame body to move downward. A reset elastic member 7755 is provided between the frame body and the mounting body 773. The contact plate 776 is driven by the reset elastic member 7755 to reset upward during the descending process of the moving component 75, and a linkage member is provided on the inside of the frame body and is connected to the rotating shaft 774, thereby driving the rotating shaft 774 to rotate during the movement of the frame body.

[0038] It should be noted that the vertical distance between the contact plate 776 that is not in contact with the outer body 73 and the ignition probe 771 is greater than the axial length of the outer body 73, thereby ensuring that the projection of the rotating ignition probe 771 on the plane where the axis of the nozzle tube is located does not interfere with the top of the nozzle tube, that is, the ignition probe 771 will not interfere with the nozzle tube and the outer body 73 when rotating.

[0039] Specifically, a side branch 7741 is extended laterally from the rotating shaft 774, the frame body includes a front plate 7751 and a rear plate 7752, the linkage member includes a first elastic member 7753 and a second elastic member 7754, the front plate 7751 and the rear plate 7752 are connected to the side branch 7741 through the first elastic member 7753 and the second elastic member 7754, respectively, on this basis, the state of the linkage member includes a main state and a side standby state, and the lifting of the frame body drives the two linkage members to perform state conversion so that the rotating shaft 774 rotates; in the main force state, the linkage part provides the side branch 7741 with elastic force to drive the rotating shaft 774 to rotate around the axis, and the other linkage part is automatically in the side standby state. In the side standby state, the linkage part applies vertical or vertically inclined elastic force to the side branch 7741. In the main force state, the linkage part applies force to the side branch 7741 of the rotating shaft 774, so that the side branch 7741 contacts with the frame or the mounting body 773 and remains relatively still, so that the top ignition probe 771 is stabilized in the storage state or the extended state;

[0040] At the same time, the first end of the first elastic member 7753 and the second elastic member 7754 are connected to the side branch 7741, and the ends are connected to the front plate 7751 and the rear plate 7752 respectively. The ends of the first elastic member 7753 and the second elastic member 7754 are at different horizontal heights. When the frame moves, the end of the linkage member in the main force state is vertically away from the side branch 7741, and the end of the linkage member in the side standby state is vertically close to the side branch 7741. Since the distance between the end of the linkage member and the side branch 7741 is shortened, the direction of the force applied by the linkage member to the side branch 7741 is changed, thereby driving the side branch 7741 to rotate.

[0041] In this embodiment, the first elastic member 7753 and the second elastic member 7754 are springs, and it should be noted that the distance between the end of the linkage member in the side standby state and the side branch 7741 is greater than the limit compression length of the linkage member.

[0042] In summary, in a specific implementation, natural gas is supplied to the main gas pipe 5, and the natural gas is sprayed into the kiln through the burner pipe 71. The cylinder-type mobile actuator 76 drives the base 753 to rise, the material rack 751 rises and drives the fire ring 72 to rise, and the ignition assembly 77 follows the rise. During the rising process, the contact plate 776 contacts the bottom of the outer package 73, and the ignition assembly 77 continues to rise, so that the contact plate 776 drives the frame to descend relative to the mounting body 773, as shown in FIG. Figure 7The figure shows a basic state of the cooperation between the linkage member and the side branch 7741. The frame body descends to make the end of the first elastic member 7753 descend relative to the side branch 7741, shortening the distance to the side branch 7741, so that the first elastic member 7753 in the side waiting state gradually changes from vertical to horizontal, providing horizontal elastic force for the side branch 7741 and pushing the side branch 7741 to rotate. The end of the second elastic member 7754 on the other side descends relative to the side branch 7741 and shortening the distance to the side branch 7741, so that the second elastic member 7754 in the main force state gradually changes from horizontal to vertical, reducing the elastic support for the side branch 7741 driven by the first elastic member 7753 and giving way. , let the side branch 7741 drive the rotating shaft 774 to rotate, so that the ignition probe 771 at the top of the rotating shaft 774 extends outward from the stored state to the top of the burner tube 71 to ignite the ejected natural gas. The temperature probe 772 is similarly swung out to detect the temperature near the burner tube 71 to ensure successful ignition. Then the cylinder type mobile actuator 76 drives the base 753 to descend, so that the ignition assembly 77 is reset, and the fire pressure ring 72 is pressed onto the burner tube 71 to stabilize the burning flame. Then the hydrogen pipe 6 is connected to mix with the natural gas, and the supply of natural gas is gradually increased to increase the flame, so that the temperature inside the kiln body 1 is raised to the required temperature for ceramic sintering.

[0043] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
