Description

Technical Field

[0001] The utility model relates to the technical field of boiler sootblowing, in particular to a parallel expansion type shock wave sootblower. Background Art

[0002] like Figure 3 As shown, the existing shock wave soot blower includes a shock wave generator 1, a pipe body 2 arranged on the shock wave generator 1, and a shock wave nozzle 5 connected to one end of the pipe body 2. When soot is blown at two soot blowing points on the heating surface of the boiler, two shock wave generators 1 need to be arranged, and the shock wave nozzle 5 on each shock wave generator 1 is aimed at a soot blowing point on the heating surface of the boiler for soot blowing. The compressed air in the existing shock wave generator 1 needs to reach a certain pressure to be used normally. For example, at some customer sites where the compressed air pressure is lower than 0.5MPa, the air shock wave soot blower of the prior art cannot be used due to the low pressure. Utility Model Content

[0003] The utility model aims to provide a parallel expansion type 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: a parallel expansion type shock wave soot blower, including two or more shock wave generators, each two adjacent shock wave generators are connected with a connecting pipe, the connecting pipe is used to connect the inside of the two adjacent shock wave generators, a two-way supercharger is arranged on the connecting pipe, each shock wave generator is provided with a tube body, one end of the tube body is provided with a shock wave nozzle, and the other end is provided with a gas release mechanism.

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

[0006] As a further improvement of the above technical solution, the inner diameter of the tube body is set to 50-150 mm.

[0007] As a further improvement of the above technical solution, the shock wave generator is a tank containing compressed air.

[0008] As a further improvement of the above technical solution, both ends of the tube body pass through the shock generator, and both ends of the tube body are connected to the side wall of the shock generator by welding or by flanges.

[0009] As a further improvement of the above technical solution, the gas release mechanism includes a pressure release valve and a sealing diaphragm connected to the pressure release valve. The sealing diaphragm is a circular rubber sheet. The sealing diaphragm is controlled by the pressure release valve so that the sealing diaphragm blocks the opening of the tube body or separates from the opening of the tube body.

[0010] As a further improvement of the above technical solution, the bidirectional booster arranged on the connecting pipe adopts a solenoid valve, and the compressed air in two adjacent shock wave generators is connected or isolated by opening and closing the solenoid valve.

[0011] The beneficial effects of the utility model are as follows: two or more shock wave generators are connected in parallel through a connecting pipe and a bidirectional supercharger is arranged on the connecting pipe. Two or more shock wave generators are connected in parallel, and the shock wave nozzles on the two or more shock wave generators can blow soot at two or more soot blowing points on the boiler heating surface. When the bidirectional supercharger is turned on, the volume of compressed air released at a single time is greatly increased, thereby greatly improving the soot blowing intensity of the shock wave. Compared with the shock wave soot blower using a single shock wave generator in the prior art, under the condition of achieving the same soot blowing effect, the compressed air pressure required by the system is greatly reduced.

[0017] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0018] In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances. Example 1

[0020] like Figure 1 As shown, a parallel expansion type shock wave soot blower provided in Example 1 of the utility model includes two shock wave generators 1, a connecting pipe 3 is connected between the two shock wave generators 1, the connecting pipe 3 is used to connect the inside of the two shock wave generators 1, a bidirectional booster 4 is arranged on the connecting pipe 3, each shock wave generator 1 is provided with a pipe body 2, one end of the pipe body 2 is provided with a shock wave nozzle 5, and the other end is provided with a gas release mechanism 6.

[0021] The shock wave generator 1 can be a tank containing compressed air. An air inlet is provided on the shock wave generator 1, and air is filled into the shock wave generator 1 through the air inlet, wherein the air filled into the shock wave generator 1 is compressed gas. The shock wave generator 1 is a pressure vessel, and its internal pressure can be 0.3-0.6Mpa, which is used to store compressed air. Both ends of the tube body 2 pass through the shock wave generator 1, and both ends of each tube body 2 are connected to the side wall of the shock wave generator 1 by welding or by flanges. The compressed air ejected from the shock wave nozzle 5 connected to the tube body 2 generates shock waves, and the inner diameter of the tube body 2 is set to 50-150mm.

[0022] The gas release mechanism 6 may include a pressure release valve and a sealing diaphragm connected to the pressure release valve. The sealing diaphragm may be a circular rubber sheet. The sealing diaphragm is controlled by the pressure release valve so that the sealing diaphragm blocks the opening of the tube body 2 or the sealing diaphragm is separated from the opening of the tube body 2. When the sealing diaphragm blocks the opening of the tube body 2, the sealing diaphragm isolates the shock wave generator 1 from the tube body 2; when the sealing diaphragm is separated from the opening of the tube body 2 (i.e., when the diaphragm breaks), the compressed air in the shock wave generator 1 can enter the tube body 2.

[0023] The two shock wave generators 1 are connected in parallel through a connecting pipe 3 and a bidirectional supercharger 4 is arranged on the connecting pipe 3. After the two shock wave generators 1 are connected in parallel and the bidirectional supercharger 4 is turned on, the volume of compressed air released at a single time is doubled, thereby greatly improving the soot blowing intensity of the shock wave.

[0024] After many tests by our company, it is shown that after two shock wave generators 1 are connected in parallel, when the compressed air is about 0.35MPa, the soot blowing effect is almost the same as that produced by the existing single shock wave generator 1 when the compressed air is about 0.5MPa. At some customer sites where the compressed air pressure is lower than 0.5MPa, the air shock wave soot blower of the existing technology cannot be used due to the low pressure, but after the two shock wave generators 1 are connected in parallel, as long as the compressed air pressure is higher than 0.35MPa, the air shock wave soot blower can be used, which greatly improves the use range of the air shock wave soot blower. Compared with the shock wave soot blower using a single shock wave generator in the prior art, under the condition of achieving the same soot blowing effect, after the two shock wave generators 1 are connected in parallel and the bidirectional supercharger 4 is turned on, the compressed air pressure required by the system is greatly reduced. Example 2

[0025] like Figure 2 As shown, a parallel expansion type shock wave soot blower provided in Example 2 of the utility model includes three shock wave generators 1, and a connecting pipe 3 is connected between each two adjacent shock wave generators 1. The connecting pipe 3 is used to connect the interiors of the two adjacent shock wave generators 1, and a bidirectional booster 4 is arranged on the connecting pipe 3. Each shock wave generator 1 is provided with a pipe body 2, and a shock wave nozzle 5 is arranged at one end of the pipe body 2, and a gas release mechanism 6 is arranged at the other end.

[0026] Those skilled in the art should understand that the above-mentioned parallel expansion shock wave soot blower may also include four or more shock wave generators 1 , and a connecting pipe 3 is connected between each two adjacent shock wave generators 1 , and a bidirectional supercharger 4 is provided on the connecting pipe 3 .

[0027] In the above embodiment, preferably, the bidirectional booster 4 provided on the connecting pipe 3 can adopt an electromagnetic valve, and the compressed air in two adjacent shock wave generators 1 can be connected or the compressed air in two adjacent shock wave generators 1 can be isolated by opening and closing the electromagnetic valve. When the electromagnetic valve is opened, the volume of compressed air released at a single time is greatly increased, thereby greatly improving the soot blowing intensity of the shock wave.

[0028] Preferably, the novel shock wave soot blower further comprises a control mechanism, which is connected to the shock wave generator 1, the gas release mechanism 6 and the bidirectional supercharger 4, and is used to control the internal connection or isolation of two adjacent shock wave generators 1, the charging of compressed air provided by the air compressor into the shock wave generator 1, the ejection of compressed air from the shock wave generator 1, and the opening and closing of the pressure release valve of the gas release mechanism 6. The control mechanism may adopt a PLC controller, which controls the internal connection or isolation of two adjacent shock wave generators 1, the charging of air into the shock wave generator 1, the ejection of compressed air from the shock wave generator 1, and the opening and closing of the pressure release valve of the gas release mechanism 6 through the control mechanism, thereby improving the automation degree of the novel shock wave soot blower and thus improving the working efficiency.

[0029] Compared with the prior art, two or more shock wave generators 1 are connected in parallel through a connecting pipe 3 and a bidirectional supercharger 4 is provided on the connecting pipe 3. The shock wave nozzles 5 on the two or more shock wave generators 1 can blow soot at two or more soot blowing points on the boiler heating surface. When the bidirectional supercharger 4 is turned on, the volume of compressed air released at a time is greatly increased, thereby greatly improving the soot blowing intensity of the shock wave. Compared with the shock wave soot blower using a single shock wave generator in the prior art, the compressed air pressure required by the system is greatly reduced under the condition of achieving the same soot blowing effect.

[0030] Any details not mentioned in the above specific embodiments of the present invention belong to the known technologies in the art and can be implemented with reference to the known technologies.

[0031] The above is based on the ideal embodiment of the utility model. Through the above description, relevant personnel can make various changes and modifications without deviating from the technical concept of the utility model. The technical scope of this utility model is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
