Description

Technical Field

[0001] The invention relates to the technical field of glass wool production, and in particular to a high thermal efficiency pressurized kiln for glass wool production. Background Art

[0002] Glass wool belongs to a category of glass fiber and is a man-made inorganic fiber. Glass wool is a cotton-like material made by fiberizing molten glass. Its chemical composition belongs to glass and it is an inorganic fiber. It has good molding, low volume density, low thermal conductivity, thermal insulation, good sound absorption, corrosion resistance, and stable chemical properties. Nowadays, glass wool is mostly prepared by centrifugal fiberizing device, that is, the molten glass liquid is placed in a high-speed rotating barrel with holes on the side wall, and the molten glass liquid is thrown out from the tiny holes by centrifugal inertia to obtain glass fiber. After the glass fiber is aggregated and compressed, glass wool is obtained. Its working principle is similar to the preparation of cotton candy. In the above preparation process, the melting process is generally carried out in a pressurized kiln, and the glass is melted at high temperature in the kiln to obtain molten glass. As a waste heat recovery mechanism, the regenerator is widely used in various kilns. The function of the regenerator is to recover the heat in the high-temperature flue gas of the kiln, and to preheat the fuel and combustion-supporting materials through the recovered heat, so that the low calorific value fuel can be burned at high temperature, producing the combustion effect of the high calorific value fuel, so that the high calorific value fuel can be burned at a higher temperature, generating more heat, and playing a heating role. The heat storage body in the traditional regenerator is mostly made of checker bricks. Although it has good fire resistance, heat preservation and heat storage performance, its thermal conductivity is average, resulting in a large room for improvement in the speed of waste heat recovery and preheating. Summary of the invention

[0026] like Figure 1 As shown, a high thermal efficiency pressurized kiln for glass wool production includes a kiln body and a heat storage chamber. The kiln body may include a melting pool 1, a liquid flow channel 2 matched with the melting pool 1, a feeding port 3, a first small furnace 4, a smoke extraction mechanism 5 and a second small furnace 6. The first small furnace 4 and the second small furnace 6 are provided with an ignition device, such as Figure 1 The two U-shaped arrows in the melting pool 1 are the directions of the flame spraying of the first small furnace 4 and the second small furnace 6, which are horseshoe-shaped. The liquid flow channel 2 is used for discharging molten glass liquid, the feeding port 3 is used for feeding glass raw materials into the melting pool 1, and the smoke extraction mechanism 5 is used for extracting the high-temperature smoke in the melting pool 1. Figure 1 The directions of the multiple arrows near the smoke extraction mechanism 5 are the directions of high-temperature smoke transmission. Two heat storage chambers can be provided, namely a first heat storage chamber 11 and a second heat storage chamber 16 . The two heat storage chambers are arranged adjacent to each other and are both arranged beside the melting pool 1 .

[0027] like Figure 1As shown, a heat storage body 12 is provided in the heat storage chamber. In order to improve the stability of the heat storage body 12, a supporting mechanism 1201 can be provided around the outer side of the heat storage body 12. A heat storage cavity is constructed in the heat storage body 12. A plurality of heat storage cores 20 are arranged parallel to each other and spaced apart on the inner wall of the heat storage cavity. The heat storage body 12 is connected with a smoke inlet channel for inputting smoke into the heat storage cavity, a smoke exhaust channel for outputting smoke from the heat storage cavity, a fuel channel for inputting fuel into the heat storage cavity, an air channel for inputting combustion-supporting air into the heat storage cavity, and an air channel for outputting smoke from the heat storage cavity. The mixing channel for outputting the fuel-air mixture in the cavity, wherein the input ends of the smoke inlet channel, the fuel channel and the air channel are all located below the heat storage core 20, and the output ends of the smoke exhaust channel and the mixing channel are all located above the heat storage core 20, so that the fuel, air and high-temperature flue gas can pass through all the heat storage cores 20 from bottom to top. Specifically, in some embodiments, the smoke inlet channel includes a first smoke inlet channel 8 and a second smoke inlet channel 9, one end of the first smoke inlet channel 8 and the second smoke inlet channel 9 are connected to the smoke extraction mechanism 5, and the other end is connected to the first heat storage chamber 1 respectively. 1 and the heat storage body 12 in the second heat storage chamber 16, the smoke exhaust channel includes a first smoke exhaust channel 13 and a second smoke exhaust channel 17, the first smoke exhaust channel 13 and the second smoke exhaust channel 17 are respectively connected to the heat storage body 12 in the first heat storage chamber 11 and the heat storage body 12 in the second heat storage chamber 16, the fuel channel includes a first fuel channel 14 and a second fuel channel 18, the first fuel channel 14 and the second fuel channel 18 are respectively connected to the heat storage body 12 in the first heat storage chamber 11 and the heat storage body 12 in the second heat storage chamber 16 12, the air channel includes a first air channel 15 and a second air channel 19, the first air channel 15 and the second air channel 19 are respectively connected to the heat storage body 12 in the first heat storage chamber 11 and the heat storage body 12 in the second heat storage chamber 16, the mixing channel includes a first mixing channel 7 and a second mixing channel 10, one end of the first mixing channel 7 and the second mixing channel 10 are respectively connected to the first small furnace 4 and the second small furnace 6, and the other end is respectively connected to the heat storage body 12 in the first heat storage chamber 11 and the heat storage body 12 in the second heat storage chamber 16.

[0028] like Figure 1As shown, through the above technical solution, when working, the first fuel channel 14 and the first air channel 15 respectively input fuel and combustion-supporting air into the first regenerator 11, and the fuel and air pass through the regenerator 12 and the first mixing channel 7 in turn, and are ignited in the first small furnace 4. As the air is pressurized, the flame is sprayed into the melting pool 1 in a U shape, so that the glass in the melting pool 1 is gradually melted, and the high-temperature flue gas generated during this period is sucked away by the smoke extraction mechanism 5, and the high-temperature flue gas enters the regenerator 12 in the second regenerator 16 along the second smoke inlet channel 9. During this period, part of the residual heat in the high-temperature flue gas is absorbed by the regenerator 12, and finally the flue gas is discharged from the second regenerator 16 through the second smoke exhaust channel 17. After the flame is reversed, the fuel and combustion-supporting air are respectively input into the second heat storage chamber 16 through the second fuel channel 18 and the second air channel 19. The fuel and air pass through the heat storage body 12 and the second mixing channel 10 in turn. During this period, the fuel and air are heated by the heat in the heat storage body 12 to achieve preheating of the fuel and air. Thereafter, the fuel and air are transmitted to the second small furnace 6 and ignited. The high-temperature flue gas generated during this period is extracted by the smoke extraction mechanism 5, and the high-temperature flue gas enters the heat storage body 12 of the second heat storage chamber 11 along the first smoke inlet channel 8 to achieve waste heat recovery. Then the flame reversal is continued, and this is repeated, thereby achieving uninterrupted heat storage and heat release and full utilization of heat.

[0029] It should be noted here that the above technical solution also includes various fluid transmission mechanisms (such as pumps, fans, etc.) and valves (such as one-way valves, check valves, fire dampers, etc.), but since these mechanisms are all conventional settings in existing kilns, the relevant contents of these mechanisms will not be repeated in this embodiment.

[0030] like Figure 4-7 As shown, the heat storage core 20 includes a heat storage barrel 2001 and a heat conductive core 2010 axially arranged inside the heat storage barrel 2001. The upper side of the heat storage barrel 2001 is provided with a first opening 2002, a second opening 2003 and a third opening 2004. The first opening 2002 and the third opening 2004 are symmetrically arranged on both sides of the second opening 2003. The outer side wall of the heat storage barrel 2001 located between the first opening 2002 and the second opening 2003 is provided with a first outer guide plate 2005 bent toward the first opening 2002. A first inner guide plate 2006 bent toward the first opening 2002 is provided on the inner side wall of the heat storage cylinder 2001 between the first opening 2002 and the second opening 2003, a second outer guide plate 2007 bent toward the third opening 2004 is provided on the outer side wall of the heat storage cylinder 2001 between the third opening 2004 and the second opening 2003, and a second inner guide plate 2008 bent toward the third opening 2004 is provided on the inner side wall of the heat storage cylinder 2001 between the third opening 2004 and the second opening 2003. Figure 4As shown, when the fluid is blown upward from the bottom of the heat storage cylinder 2001, the fluid will be divided into two under the blocking effect of the heat storage cylinder 2001 to achieve diversion, and the diverted fluid will wrap the heat storage cylinder 2001 (as shown in FIG. Figure 4 The arrow and its direction shown are the fluid flow path and its direction), thereby eliminating the heat conduction dead angle and achieving faster heat conduction. In addition, due to the Coanda effect (i.e., when the fluid flows along the surface of a protruding object, it will deviate from the original flow direction and change to a tendency to flow along the surface of the protruding object), a part of the fluid will flow along the outer surface of the heat storage cylinder 2001. When the fluid flows to the first opening 2002 and the third opening 2004, the fluid will be guided to flow into the heat storage cylinder 2001 under the guidance of the first outer guide plate 2005 and the second outer guide plate 2007. After being in the heat storage cylinder 2001, the fluid will make a circular motion in the heat storage cylinder 2001 under the guidance of the first inner guide plate 2006 and the second inner guide plate 2008. During this period, the fluid fully contacts and exchanges heat with the heat-conducting core 2010 in the heat storage cylinder 2001. Finally, the fluid will flow out of the heat storage cylinder 2001 through the second opening 2003. During the above period, when there is fluid flowing from bottom to top to When the heat storage cylinder 2001 is in contact with the fluid, the heat storage cylinder 2001 and the heat conductive core 2010 can fully contact with the fluid and fully exchange heat. Since the heat conductive core 2010 is completely wrapped by the heat storage cylinder 2001 and the heat conductive core 2010 in the heat storage cylinder 2001 can only exchange heat with the outside through three openings, the heat dissipation loss of the heat conductive core 2010 is very low in a static environment. However, once the fluid blows toward the heat storage cylinder 2001, the fluid can easily blow into the heat storage cylinder 2001 and exchange heat with the heat conductive core 2010. 010 is in full contact, which can achieve rapid heat conduction. In actual use, when high-temperature flue gas flows from bottom to top to the heat storage cylinder 2001, the high-temperature flue gas can be easily blown into the heat storage cylinder 2001 to quickly heat up the heat-conducting core 2010, thereby effectively improving the waste heat recovery efficiency of the heat storage core 20. When the gas and air flow from bottom to top to the heat storage cylinder 2001, the gas and air can also be easily blown into the heat storage cylinder 2001 to quickly exchange heat with the heat-conducting core 2010, thereby achieving efficient and rapid preheating. Figure 5 As shown, under the diversion effect of the multi-layer heat storage core 20, the fluid divided into small streams can more fully exchange heat with the heat storage tube 2001 and the heat conductive core 2010, thereby realizing high-efficiency, low-loss waste heat recovery and fluid preheating. In the above structure, the heat storage chamber and the heat storage body 12 can both be built of refractory insulation bricks, the heat storage tube 2001 can also be made of the same material as the refractory insulation bricks, and the heat conductive core 2010 can be made of a metal material with good thermal conductivity.

[0031] In summary, the heat storage tube 2001 in the heat storage core 20 ensures the fire resistance, heat preservation and heat storage performance of the heat storage core 20, and the heat conductive core 2010 in the heat storage tube 2001 enables the heat storage core 20 to have good thermal conductivity. Under the wrapping effect of the heat storage tube 2001, the heat conductive core 2010 also has good heat storage performance. Combined with the Coanda effect in fluid mechanics, under the action of multiple heat storage cores 20, the fluid can be dispersed, which is more conducive to the rapid conduction of heat, and the fluid can smoothly enter the heat storage tube 2001 through the multiple openings on the heat storage tube 2001 to transfer heat to the heat conductive core 2010, so that the heat conductive core 2010 can be directly in full contact with the fluid, and the heat conduction effect is good. In summary, this kind of high thermal efficiency pressurized kiln for glass wool production can take into account excellent fire resistance, heat preservation, heat storage and thermal conductivity, effectively improve the speed of waste heat recovery and preheating, and has higher thermal energy utilization efficiency than traditional kilns.

[0032] In some embodiments, Figure 2 and Figure 3 As shown, the heat storage body 12 is a flat-top pyramid structure that is wide at the top and narrow at the bottom. The multiple heat storage cores 20 are divided into multiple layers along the longitudinal direction. The number of heat storage cores 20 in each layer increases from bottom to top, and the overall arrangement is an inverted triangle. This arrangement of the heat storage cores 20 can make the fluid transmitted from bottom to top be divided layer by layer (see Figure 5 The fluid path and its direction are shown by the arrows), and the heat exchange rate of small fluids is faster, thus achieving more sufficient heat exchange.

[0033] The fluid can enter the heat storage cartridge 2001 through the first opening 2002 and the third opening 2004 respectively, and form two fluid vortices in the heat storage cartridge 2001. Therefore, in order to adapt the activity path of the fluid, in some embodiments, as Figure 4 As shown, there are two heat-conducting cores 2010 in each heat storage tube 2001. The two heat-conducting cores 2010 in the same heat storage tube 2001 do not contact each other and are symmetrically arranged on both sides of the axis of the heat storage tube 2001. A gap is left between the heat-conducting core 2010 and the inner wall of the heat storage tube 2001. In this way, the two heat-conducting cores 2010 can better adapt to the flow path of the fluid in the heat storage tube 2001, making the fluid transmission smoother and achieving more sufficient heat exchange.

[0034] In some embodiments, Figure 4 As shown, in order to improve the heat exchange performance of the heat-conducting core 2010, a plurality of heat-conducting fins 2011 extending radially outward may be provided on the outer wall of the heat-conducting core 2010. These heat-conducting fins 2011 increase the heat exchange area and can effectively improve the heat exchange efficiency between the heat-conducting core 2010 and the fluid. The heat-conducting core 2010 and the heat-conducting fins 2011 are preferably made of copper.

[0035] In some embodiments, Figure 4 As shown, a guide rib 2009 is provided on the side of the inner wall of the heat storage cylinder 2001 away from the second opening 2003. The guide rib 2009 is a triangular strip structure and is located in the middle of the two heat-conducting cores 2010. The surface of the guide rib 2009 facing the heat-conducting core 2010 is a concave arc surface. The guide rib 2009 can guide the fluid to flow toward the second opening 2003, making the fluid transmission smoother.

[0036] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
