Description

Technical Field

[0001] This utility model relates to the field of heat recovery technology, and more specifically, to a device for utilizing the heat of flue gas using ceramsite proppant. Background Technology

[0002] Ceramsite proppant is a spherical particle made from bauxite through powder granulation and sintering. It is widely used in fracturing operations in the oil and gas industry. Compared with natural quartz sand, ceramsite proppant has advantages such as high strength, low cost, and good chemical stability. It is more effective at supporting fractures, increasing conductivity, and achieving the goal of increasing production.

[0003] The firing of ceramsite proppant is a high-temperature industrial process that consumes a lot of energy. The exhaust gas contains a high amount of heat, which is not utilized, resulting in a waste of resources.

[0004] Chinese Patent No. CN218846149U discloses a device for recovering heat from flue gas in an incinerator. This device can completely receive the hot air discharged from the cyclone dust collector and reintroduce it into the incinerator through the air inlet pipe, blower, and air delivery pipe. This results in a high temperature of air injected into the incinerator, which in turn keeps the flame in the incinerator at its highest temperature, thus achieving the best combustion effect.

[0005] However, in actual use, because the oxygen content in the flue gas discharged from the incinerator is lower than that in the air, the purified flue gas is less effective at supporting the combustion of the combustibles than air, which is not conducive to the incinerator maintaining the highest temperature.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] As attached Figures 1-7 The diagram shows a base plate 1, a conversion mechanism on the top of the base plate 1, a support assembly on one side of the conversion mechanism, and a screening mechanism on the top of the support assembly.

[0032] The conversion mechanism includes a conversion cylinder 2 set on the top of the base plate 1. A spiral tube 3 is set inside the conversion cylinder 2. Multiple connecting columns 4 are set between the spiral tube 3 and the conversion cylinder 2. The two ends of the connecting columns 4 are fixedly connected to the surface of the spiral tube 3 and the inner wall of the conversion cylinder 2, respectively. An air inlet pipe 5 is connected to the top of the spiral tube 3, and an air outlet pipe 6 is connected to the bottom of the spiral tube 3. Both the air inlet pipe 5 and the air outlet pipe 6 extend to the outside of the conversion cylinder 2. Multiple heat absorption plates 7 are set on the surface of the spiral tube 3.

[0035] The inlet pipe 22, the outlet pipe 23, the outlet pipe 8, and the conversion cylinder 2 are all made of nickel alloy.

[0036] The above operations can promote the combustion of materials inside the furnace, maintain the temperature of the furnace, and achieve the best firing effect and the purity of the fired products.

[0037] Specifically, when the flue gas from the inlet pipe 23 enters the inside of the conversion cylinder 2 and fills the entire conversion cylinder 2, the used flue gas is transported to the purification equipment through the outlet pipe 8 to treat the harmful substances in the flue gas.

[0038] Meanwhile, air is blown into the air inlet pipe 5 through an external blower assembly. The air enters the spiral tube 3 through the air inlet pipe 5. The air inside the spiral tube 3 absorbs the heat emitted by the flue gas through the surface of the spiral tube 3 and the heat absorption plate 7, causing the temperature of the air inside the spiral tube 3 to rise. The high-temperature air is discharged from the spiral tube 3, passes through the air outlet pipe 6, and is discharged into the combustion furnace. The oxygen in the air promotes the combustion of the combustibles inside the combustion furnace. Because the air temperature is high and there are no impurities contained in the flue gas, the flame in the combustion furnace can always maintain the highest temperature, thereby achieving the best firing effect and the purity of the fired product.

[0039] In a specific embodiment, as shown in the appendix Figure 1 As shown, the bracket assembly includes a support plate 9 set on the top of the base plate 1.

The other end of the smoke outlet pipe 23 is connected to the conversion cylinder 2.

[0041] By performing the above operations, the device can operate more stably.

[0042] Specifically, the two extension plates 11 fix the air outlet pipe 6, and the placement port 10 at the top of the support plate 9 fixes the screening box 13 inside the placement port 10.

[0043] In a specific embodiment, as shown in the appendix Figure 4 , 5 As shown in Figures 6 and 7, the screening mechanism includes a screening box 13 disposed inside the placement port 10, a collection port 14 is provided on one side of the screening box 13, a drawer 15 is slidably disposed inside the collection port 14, and a first handle 16 is provided on the surface of the drawer 15.

[0045] The top of the screen 18 is provided with a second handle 20, and the surface of the cover plate 19 is provided with a retention port 21, which is adapted to the second handle 20.

[0046] Through the above operations, the initial filtration of flue gas can be easily achieved, and impurities can be easily discharged, preventing subsequent accumulation of impurities, blockage of pipes, and impact on the normal operation of the device.

[0047] Specifically, after the combustion furnace produces flue gas, the flue gas enters the inside of the screening box 13 through the flue pipe 22, the gas in the flue gas flows into the flue pipe 23 through the screening net 18, enters the conversion mechanism, and the impurities in the flue gas adhere to the surface of the screening net 18 or accumulate in the inside of the drawer 15;

[0048] When the device stops working, the cover plate 19 hingedly arranged on the top of the screening net 18 can be opened, the screening net 18 is pulled out through the second handle 20, then the drawer 15 is pulled out by pulling the first handle 16, the impurities in the inside of the screening net 18 and the drawer 15 are removed, and finally the drawer 15 and the screening net 18 are sequentially returned to the original positions and fixed.

[0052] When the device stops working, the cover plate 19 hingedly arranged on the top of the screening net 18 can be opened, the screening net 18 is pulled out through the second handle 20, then the drawer 15 is pulled out by pulling the first handle 16, the impurities in the inside of the screening net 18 and the drawer 15 are removed, and finally the drawer 15 and the screening net 18 are sequentially returned to the original positions and fixed.
