Description

Technical Field

[0001] The utility model relates to the technical field of boilers, in particular to a novel high-efficiency boiler steam recovery and utilization device. Background Art

[0002] A boiler is an energy conversion device. The energy input into the boiler includes chemical energy and electrical energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. The hot water or steam generated in the boiler can directly provide the required thermal energy for industrial production and people's lives, and can also be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator.

[0003] Boilers generally recover waste heat in order to save energy. If the diameter of the pipe is too large, the same steam flow rate will result in a higher linear velocity. Large diameter pipes may increase the flow rate of steam in the pipe, causing the steam to pass through the pipe too quickly. When recovering the waste heat of boiler steam, high pressure conditions with more steam will be encountered. In order to meet certain steam flow requirements, larger diameter pipes are required to prevent damage to the machine body caused by excessive pressure caused by excessive steam, thereby increasing the flow rate of steam. However, when there is less steam, the rapid passage of the waste heat recovery pipe will result in insufficient waste heat recovery of the steam, resulting in waste. Summary of the invention

DETAILED DESCRIPTION

[0022] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a novel high-efficiency boiler steam recovery and utilization device, comprising a boiler 1, a water inlet pipe 2 is fixedly connected to the bottom of the boiler 1, a water outlet pipe 3 is fixedly connected to the top of the boiler 1, a recovery mechanism 4 is arranged on the surface of the boiler 1, and the recovery mechanism 4 comprises: an exhaust pipe 41, a first annular recovery pipe 42, a second annular recovery pipe 43, a connecting pipe 44, a fixing ring 45, a fixing plate 46, a spring 47, a blocking disk 48, a guide rod 49, and a blocking plate 410.

[0023] One end of an exhaust pipe 41 is fixedly connected to the top of the boiler 1, and the other end of the exhaust pipe 41 is fixedly connected to a first annular recovery pipe 42. One end of a connecting pipe 44 is fixedly connected to the surface of the first annular recovery pipe 42, and the other end of the connecting pipe 44 is fixedly connected to a second annular recovery pipe 43. A fixing ring 45 is fixedly connected to the inner wall of the second annular recovery pipe 43, and a fixing plate 46 is fixedly connected to the inner wall of the second annular recovery pipe 43. One end of a spring 47 is fixedly connected to the surface of the fixing plate 46, and a blocking disk 48 is fixedly connected to the other end of the spring 47. A guide rod 49 is fixedly connected to the surface of the blocking disk 48 close to the spring 47. A blocking plate 410 is fixedly connected to the inner wall of the first annular recovery pipe 42. When excess steam enters the first annular recovery pipe 42 through the exhaust pipe 41, the blocking plate 410 in the first annular recovery pipe 42 plays a role of deceleration, so that the steam slowly passes through the first annular recovery pipe 42 to perform secondary heating on the boiler 1, which is convenient for efficiently recovering the heat of the steam. When there is more steam, a larger steam pressure passes through the connecting pipe 42. The steam passes through the first annular recovery pipe 42 and the second annular recovery pipe 43 through the first annular recovery pipe 44, and then contacts and squeezes the blocking plate 48, so that the steam can enter the bottom of the second annular recovery pipe 43 through the fixing ring 45. At this time, the first annular recovery pipe 42 and the second annular recovery pipe 43 are exhausted at the same time to avoid the large steam pressure from damaging the body, which plays the role of a protective device. The first annular recovery pipe 42 is fixedly connected to the surface of the boiler 1, and the second annular recovery pipe 43 is fixedly connected to the surface of the boiler 1, so that the first annular recovery pipe 42 and the second annular recovery pipe 43 are stably installed and fixed. The first annular recovery pipe 42 and the second annular recovery pipe 43 are fixed to the surface of the boiler 1, which is also conducive to strengthening the heat transfer. The surface of the guide rod 49 is slidably connected to the inner wall of the fixing plate 46, so that the guide rod 49 slides stably left and right. The blocking plate 410 is an oblique array plate, and the oblique plate can block and slow down the steam. The first annular recovery pipe 42 and the second annular recovery pipe 43 are connected through the connecting pipe 44. When the air pressure in the first annular recovery pipe 42 is too high, it is discharged to the second annular recovery pipe 43 through the connecting pipe 44.

[0024] A water inlet preheating mechanism 5 is arranged on the surface of the boiler 1, and the water inlet preheating mechanism 5 includes: a discharge pipe 51, the right sides of the first annular recovery pipe 42 and the second annular recovery pipe 43 are fixedly connected with the discharge pipe 51, the right side of the discharge pipe 51 is fixedly connected with a neutralization connector 52, the bottom of the neutralization connector 52 is fixedly connected with one end of the preheating air inlet pipe 53, the other end of the preheating air inlet pipe 53 is fixedly connected with a preheating sleeve 54, and the top of the preheating sleeve 54 is fixedly connected with a steam main outlet pipe 55. The steam in the first annular recovery pipe 42 and the second annular recovery pipe 43 enters the preheating sleeve 54 through the discharge pipe 51, the neutralization connector 52, and the preheating air inlet pipe 53, and preheats the water inlet pipe 2 in the preheating sleeve 54, and further utilizes and recovers the waste heat of the steam. The inner wall of the preheating sleeve 54 is penetrated by the surface of the water inlet pipe 2, and the inner wall of the preheating sleeve 54 is fixedly connected to the water inlet pipe 2, so that the high-temperature gas in the preheating sleeve 54 heats the water inlet pipe 2.

[0025] Based on the above embodiment, water is introduced into the boiler 1 through the water inlet pipe 2 , and then the hot water generated in the boiler 1 is discharged and supplied through the water outlet pipe 3 .

[0026] When excess steam enters the first annular recovery pipe 42 through the exhaust pipe 41, the blocking plate 410 in the first annular recovery pipe 42 acts to slow down the steam, so that the steam slowly passes through the first annular recovery pipe 42 to perform secondary heating on the boiler 1, thereby facilitating efficient recovery of the heat of the steam. When there is more steam, the higher steam pressure enters the second annular recovery pipe 43 through the connecting pipe 44, and then collides with the squeezing blocking disk 48, so that the steam can enter the bottom of the second annular recovery pipe 43 through the fixing ring 45. At this time, the first annular recovery pipe 42 and the second annular recovery pipe 43 are exhausted at the same time, thereby preventing the higher steam pressure from damaging the machine body, thereby acting as a protective device.

[0027] The steam in the first annular recovery pipe 42 and the second annular recovery pipe 43 enters the preheating jacket 54 through the exhaust pipe 51, the neutralization connector 52, and the preheating air intake pipe 53, preheats the water inlet pipe 2 in the preheating jacket 54, and further utilizes and recovers the waste heat of the steam.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
