Description

Technical Field

[0001] The utility model relates to the technical field of boiler sootblowing devices, in particular to an air shock wave sootblower. Background Art

[0002] For boilers, coking of the water-cooled walls during furnace combustion, coking of the high-temperature superheater and reheater, and sooting of the rear heated surface are common and unavoidable phenomena. Coking and sooting are problems in boiler operation. Boilers are designed with a certain number of sootblowers. Commonly used sootblowers include air shock wave sootblowers, gas pulse shock wave sootblowers, and sonic sootblowers. Existing air shock wave sootblowers usually use shock tanks to store compressed air. Shock tanks are heavy and large in size, with a volume of at least 80-120 liters. The production of shock tanks requires the production qualification of pressure vessels, which increases the difficulty and cost of production and processing. Utility Model Content

[0003] The purpose of the utility model is to provide an air shock wave soot blower to overcome the problems existing in the existing equipment.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an air shock wave soot blower, including an air storage pipe, a shock wave release mechanism arranged at one end of the air storage pipe, and a shock wave nozzle arranged at the other end opposite to the air storage pipe. The air storage pipe is a three-way pipe, one end of the air storage pipe is connected to the shock wave release mechanism, and the other end of the air storage pipe is connected to the shock wave nozzle. An air inlet pipe is provided on the outer side wall of the air storage pipe, and compressed air is filled into the interior of the air storage pipe through the air inlet pipe. The air stored in the interior of the air storage pipe is compressed gas, and the volume of the entire air storage pipe is set to less than 30 liters.

[0005] On the basis of the above technical solution, the present invention can also be improved as follows:

[0010] As a further improvement of the above technical solution, the shock wave release mechanism includes a pressure relief valve and a sealing diaphragm connected to the pressure relief valve. The sealing diaphragm is a circular rubber sheet. One end of the shock wave nozzle extends into the interior of the air storage pipe and cooperates with the sealing diaphragm. The sealing diaphragm is controlled by the pressure relief valve so that the sealing diaphragm blocks the opening of the shock wave nozzle or separates from the opening of the shock wave nozzle.

[0011] As a further improvement of the above technical solution, one end of the gas storage pipe is provided with a mounting flange, the shock wave release mechanism is provided with a release valve flange, and the mounting flange is fixedly connected to the release valve flange by screws.

Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0019] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0020] like Figure 1 、 Figure 2 As shown, an air shock wave soot blower provided by a preferred embodiment of the present invention includes an air storage pipe 1, a shock wave release mechanism 2 arranged at one end of the air storage pipe 1, and a shock wave nozzle 3 arranged at the other end opposite to the air storage pipe 1.

[0021] The gas storage pipe 1 is a three-way pipe, one end of the gas storage pipe 1 is connected to the shock wave release mechanism 2, and the other end of the gas storage pipe 1 is connected to the shock wave nozzle 3. One end of the shock wave nozzle 3 extends into the gas storage pipe 1. The outer side wall of the gas storage pipe 1 is provided with an air intake pipe 11. The inner diameter of the air intake pipe 11 and the shock wave nozzle 3 can be set to DN50-DN150. Compressed air is filled into the gas storage pipe 1 through the air intake pipe 11. The gas storage pipe 1 has the functions of storing air and accumulating pressure. The air stored in the gas storage pipe 1 is compressed gas, and the volume of the entire gas storage pipe 1 is set to less than 30 liters.

[0022] The gas storage pipe 1 and the shock nozzle 3 can be made of metal. The gas storage pipe 1 and the shock nozzle 3 can be two independent components connected to each other, or they can be formed into an integrated structure. Preferably, the gas storage pipe 1 can be made of 316 stainless steel or iron.

[0023] Furthermore, the shock wave release mechanism 2 includes a pressure release valve 21 and a sealing diaphragm 22 connected to the pressure release valve 21. The sealing diaphragm 22 can be a circular rubber sheet. The sealing diaphragm 22 is controlled by the pressure release valve 21 so that the sealing diaphragm 22 blocks the opening of the shock nozzle 3 or separates from the opening of the shock nozzle 3. When the sealing diaphragm 22 blocks the opening of the shock nozzle 3, the sealing diaphragm 22 isolates the air storage pipe 1 from the shock nozzle 3; when the sealing diaphragm 22 separates from the opening of the shock nozzle 3 (that is, when the diaphragm 22 breaks), the compressed air in the air storage pipe 1 can enter the shock nozzle 3.

[0024] Furthermore, one end of the gas storage pipe 1 is provided with a mounting flange 12, and the shock wave release mechanism 2 is provided with a release valve flange 23. The mounting flange 12 is fixedly connected to the release valve flange 23 by screws, thereby fixing the gas storage pipe 1 and the shock wave release mechanism 2.

[0025] The working process of the present invention is as follows: the sealing diaphragm 22 is controlled by the pressure release valve 21, so that the sealing diaphragm 22 blocks the opening of the shock nozzle 3 or separates from the opening of the shock nozzle 3. When the sealing diaphragm 22 blocks the opening of the shock nozzle 3, the sealing diaphragm 22 isolates the gas storage pipe 1 from the shock nozzle 3; when the sealing diaphragm 22 separates from the opening of the shock nozzle 3 (that is, when the diaphragm 22 breaks), the compressed air in the gas storage pipe 1 enters the shock nozzle 3, and the compressed air is ejected from the shock nozzle 3 in a very short time, generating a shock wave of a certain intensity. The shock wave acts on the accumulated ash and coke on the heating surface of the boiler, causing them to be dispersed, cracked, crushed, and fallen off, and carried away with the flue gas, thereby improving the heat transfer effect and improving the thermal efficiency of the boiler.

[0026] The air shock wave soot blower provided by the present invention adopts an air storage pipe 1 to replace a shock wave tank, and the volume of the air storage pipe 1 is set to be less than 30 liters, which reduces the weight and volume, realizes the miniaturization of the air shock wave soot blower, and saves costs. In addition, the shock wave tank used for filling compressed air is a pressure vessel. The production of shock wave tanks requires the production qualification of pressure vessels. The present invention adopts the air storage pipe 1 to replace the shock wave tank, so that the manufacturer does not need to have the production qualification of pressure vessels, which reduces the difficulty of production and processing.

[0027] Any matters not mentioned in the above specific embodiments of the present invention belong to the known technology in the art and can be implemented with reference to the known technology.

[0028] The above description is based on the ideal embodiment of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
