Description

Technical Field

[0001] The utility model belongs to the technical field of air heat storage chambers, in particular to a novel air heat storage chamber device. Background Art

[0002] A regenerator is a waste heat recovery device that exchanges heat through heat storage and release within a medium. Its main structure includes walls, a lattice, a bottom flue, and the grate arches that support the lattice. Its internal structure, lattice structure, and material are key factors influencing heat recovery efficiency and process characteristics. Regenerators can be categorized as vertical or horizontal based on gas flow direction, and as connected or partitioned based on their structural form.

[0003] When a glass kiln uses both coal gas and natural gas as fuel, the total heat storage capacity of the regenerator is different due to the low calorific value of coal gas and the high calorific value of natural gas. Therefore, it is necessary to design two air regenerators with different structures. However, when using two different air regenerators, it is necessary to ensure that the tops of the air regenerators are on the same horizontal line. Therefore, it is also necessary to balance the longitudinal forces of the two air regenerator grate bars to ensure the stability of the bottom structure of the air regenerator. Utility Model Content

[0006] The utility model is a novel air heat storage chamber device, comprising a heat storage chamber and further comprising:

[0007] The regenerator includes X and Y and is divided into X1, X2, X3 and Y1, Y2, Y3. X is the air regenerator for gas combustion, and Y is the air regenerator for natural gas combustion.

[0009] The thermal repair door arch is arranged at the lower end of the heat storage chamber. The lower end of the thermal repair door arch is provided with a checker brick, and the lower end of the checker brick is connected to the flue.

[0010] The grate arch is set between the checker bricks and the flue, and the grate arch is made of refractory bricks and is set in an arched structure.

[0011] The force-bearing mechanism is arranged on the inner side of the grate bar arch and is used to ensure the smoothness and stability of the heat storage chamber.

[0012] Furthermore, the checker bricks are cylindrical magnesia bricks and are located inside the checker body chamber, and partition walls are evenly arranged inside the heat storage chamber.

[0013] Furthermore, leveling bricks are provided between the lattice chamber and the grate arch.

[0014] Furthermore, the force-bearing mechanism includes a climbing brick assembly and a grate foot brick piece. The climbing brick assembly is installed between X3 and Y1 and is located at the connection between the grid chamber and the grate bar grate. The grate foot brick piece is a wedge-shaped structure located below the grate bar grate.

[0015] Furthermore, the climbing brick assembly includes a grate bar arch climbing brick 1 and a grate bar arch climbing brick 2.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0027] See also Figure 1-4 As shown, the utility model is a novel air heat storage chamber device, including a heat storage chamber 1, and also includes:

[0028] The regenerator 1 includes X and Y and is divided into X1, X2, X3 and Y1, Y2, Y3. X is the air regenerator for gas combustion, and Y is the air regenerator for natural gas combustion.

[0029] The crown 12 is arranged on the top of the multiple groups of heat storage chambers 1. The crown 12 is located at the top of the entire heat storage chamber 1 and is made of refractory materials. It forms a sealed space together with other parts to prevent air leakage, improve heat exchange efficiency, reduce energy consumption and reduce environmental pollution. A small furnace 2 is arranged inside the heat storage chamber 1, and the small furnace 2 is arranged in each X and Y heat storage chamber, and the small furnace 2 is located at the front face of the kiln, so that air and flue gas can flow smoothly between the small furnace 2 and the heat storage chamber 1 to achieve heat exchange and energy exchange; the combustion air in the X1, X2 and X3 air heat storage chambers will be pre-mixed with the coal gas entering the gas heat storage chamber after entering the small furnace, and the combustion air in the Y1, Y2 and Y3 small furnaces 2 will be preheated and form a horizontal flame in the kiln with the natural gas sprayed from the natural gas spray gun. There is no partition wall 6 between the Y1 and Y2 air heat storage chambers to block the heat exchange. The calorific value of the natural gas is large and the flue gas temperature is high. This design can balance the heat.

[0030] A lattice chamber 3 is provided at the lower end of the small furnace 2, and the lattice chamber 3 is located inside the heat storage chamber 1. At the same time, the lattice chamber 3 is the core part of the heat storage chamber 1, and is equipped with lattice bricks 5, all of which are made of magnesia refractory materials. The main function is to realize heat exchange between air and flue gas. When the flue gas passes through the lattice chamber 3, the heat is transferred to the lattice. When the air passes through the lattice chamber 3, it absorbs heat from the lattice chamber 3, thereby realizing heat storage and transfer. In addition, the size of the lattice chamber 3 in the X1, X2 and X3 air heat storage chambers is 240 mm, which is gas-assisted combustion, and the total heat storage energy rate requirement is low. The lattice brick 5 is larger in size and the total specific surface area is smaller; the lattice brick 5 in the Y1, Y2 and Y3 air heat storage chambers is 220 mm, which is natural gas-assisted combustion, and the total heat storage capacity requirement is high. The lattice brick 5 is smaller in size and the total specific surface area is larger.

[0031] The thermal repair door 4 is arranged at the lower end of the heat storage chamber 1. The lower end of the thermal repair door 4 is provided with a checker brick 5. Each air heat storage chamber checker chamber 3 has a thermal repair door 4. Its main function is to repair and inspect the checker bricks 5, refractory materials, pipes, etc. in the air heat storage chamber to ensure the normal operation of the air heat storage chamber. The checker bricks 5 are all cylindrical magnesia bricks, located in the checker chamber 3. They have high refractoriness and good corrosion resistance and have a long service life. The checker bricks 5 are cylindrical magnesia bricks and are located in the checker chamber 3. The interior of the heat storage chamber 1 is evenly provided with partition walls 6. At the same time, the partition walls 6 are located in the middle of each air heat storage chamber, which plays a role in dividing the airflow and enhancing the stability of the structure. The lower end of the checker brick 5 is connected to the flue 7. Finally, the flue 7 is provided to introduce a channel for cold air, and the cold air passes through the flue 7 It enters the heat storage chamber 1 and is preheated after heat exchange with the heat storage body. The preheated air enters the small furnace 2 and then enters the kiln to participate in combustion. At the same time, it is also responsible for discharging the flue gas after heat exchange out of the kiln system; the grate arch 10 is arranged between the checker brick 5 and the flue 7, and the grate arch 10 is made of refractory bricks and is arranged in an arched structure; leveling bricks 8 are arranged between the lattice chamber 3 and the grate arch 10, which are mainly used to ensure the flatness of the bottom of the lattice chamber 3. Its lower structure is the grate arch 10. The grate arch 10 is an arched structure, so it needs to be paved with leveling bricks 8, which is conducive to the stable installation of the checker bricks 5 and reduces the problems of checker bricks 5 being uneven and heat exchange being uneven due to unevenness. It has high strength and stability, which is sufficient to withstand the pressure from above and the stress caused by thermal expansion.

[0032] The force-bearing mechanism is arranged on the inner side of the grate arch 10 and is used to ensure the stability and compressive strength of the regenerator 1. The grate arch 10 is made of refractory bricks and has an arched structure. It can better withstand the pressure from above and evenly distribute the pressure on the supporting structures on both sides. The supporting structure mainly consists of leveling bricks 8, climbing brick assemblies 9 and arch foot bricks 11. The spacing between the grate arch 10 is designed according to the size of the checker bricks 5 to form a channel that passes through the flue 7 and the checker body chamber 3, which is used for the circulation and heat exchange of gas in the kiln.

[0033] The force-bearing mechanism includes a climbing brick assembly 9 and a ridge foot brick 11. The climbing brick assembly 9 is installed between X3 and Y1 and is located at the connection between the grid body chamber 3 and the grate bar ridge 10. The ridge foot brick 11 is a wedge-shaped structure located below the grate bar ridge 10; the climbing brick assembly 9 includes a grate bar ridge climbing brick 1 901 and a grate bar ridge climbing brick 2 902. The shape structure between the grate bar ridge climbing brick 1 901 and the grate bar ridge climbing brick 2 902 is consistent, and is located at the connection between the upper ends of the two groups of grate bar ridges 10. Since the climbing brick assembly 9 is only installed at the connection between the air heat storage chamber grid body chamber 3 and the grate bar ridge 10 between X3 and Y1, the climbing brick assembly 9 is installed at the connection between the grid body chamber 3 and the grate bar ridge 10 between X3 and Y1. The connection part, which replaces some leveling bricks 8, is the key part of the present invention. Since the checker bricks 5 of the regenerators X3 and Y1 are of different sizes, the spacing between the corresponding lower grate arches 10 is also different. The spacing between the lower grate arches 10 of the regenerator X3 is 250mm, while the spacing between the lower grate arches of the regenerator Y1 is 210mm. When the connection part is built, there is a force imbalance problem. Therefore, a climbing brick assembly 9 is designed separately to press down 2.5 grate arches 10 of the regenerators X3 and Y1 respectively, covering two spacings, and balancing the uneven force problem caused by the different spacings on the left and right sides;

[0034] The foot brick 11 includes a foot brick 1101 and a foot brick 1102. The foot brick 1101 and the foot brick 1102 are triangular structures and are spliced ​​together. The foot brick 1101 and the foot brick 1102 are located at the lower end connection of the two groups of grate bar arches 10. The foot brick 11 is a wedge-shaped structure and is located below the grate bar arch 10 to support the grate bar arch 10. Its shape and size are determined according to the design of the grate bar arch. The foot brick 11 between X1 and X2, X2 and X3 is the same, Y1 and Y2, Y2 and Y 3, while the grate arches 10 between the air heat storage chambers between X3 and Y1 need to be designed separately in conjunction with the climbing brick assembly 9 because the spacing of the grate arches 10 of each grate arch is different. The X3 heat storage chamber arch foot brick piece 11 is pressed with 4 grate arches 10 and 4 spacings, and the Y1 heat storage chamber arch foot brick piece 11 is pressed with 3 grate arches 10 and 3 spacings. It cooperates with the climbing brick assembly 9 to make the checker bricks 5 of the X3 air heat storage chamber and the Y1 air heat storage chamber and the partition wall 6 therebetween evenly stressed, and together form a wall with evenly stressed structure, which is stable, safe and reliable.

[0035] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions described in the aforementioned embodiments, any equivalent replacement of some of the technical features therein, and any modification, equivalent replacement, and improvement made are within the scope of protection of the present invention.
