Technical Field

[0001] This utility model relates to a soot blowing device, or more precisely, a soot blower. Background Technology

[0002] Existing sootblowers generally cannot increase the blowing air pressure. When the dust adhesion in parts of the boiler is relatively high, it is difficult for the sootblower to clean it. For example, prior art patent 1, publication number CN203980314U, discloses a Chinese utility model patent document for a horizontal fire-tube boiler with an internal smoke box type sootblower. Figure 4 As shown, the gas source of the technical solution disclosed in this patent document cannot easily increase the gas pressure when the dust is difficult to clean, thereby improving the cleaning effect on the dust inside the boiler. Utility Model Content

A hydraulic jack is installed on the piston cylinder, and the end of the push rod of the hydraulic jack is connected to the piston. The piston and the piston cylinder are inserted and fitted together, and the side circumference of the piston is in contact with the inner wall side circumference of the piston cylinder. A first valve is installed at the outlet of the air pump, and the inlet of the first valve is connected to the outlet of the air pump. The outlet of the first valve is connected to the inside of the piston cylinder. A second valve is installed at the sealed end of the piston cylinder, and the inlet of the second valve is connected to the inside of the piston cylinder. The outlets of the second valve and the third valve are both connected to the main pipe. One end of the main pipe is connected to a branch pipe, and a nozzle is installed on the branch pipe.

[0011] The preferred embodiments of this utility model will be described below with reference to the accompanying drawings. Embodiment 1: Soot blowers, such as Figures 1-3 As shown, the device includes a main pipeline 2 and a piston booster device. The piston booster device includes a piston cylinder 4 and an air pump 8. The piston cylinder 4 is a tubular shell structure with one end sealed. A third valve 10 is installed at one end of the main pipeline 2, and the inlet of the third valve 10 is connected to the main pipeline 2. A hydraulic jack 3 is installed on the piston cylinder 4, and the push rod end of the hydraulic jack 3 is connected to a piston 5. The piston 5 and the piston cylinder 4 are inserted and fitted together, and the side circumference of the piston 5 is in contact with the inner wall side circumference of the piston cylinder 4. A first valve 7 is installed at the outlet of the air pump 8, and the inlet of the first valve 7 is connected to the outlet of the air pump 8. The outlet of the first valve 7 is connected to the interior of the piston cylinder 4. A second valve 9 is installed at the sealed end of the piston cylinder 4, and the inlet of the second valve 9 is connected to the interior of the piston cylinder 4. The outlets of the second valve 9 and the third valve 10 are both connected to a main pipe 11. One end of the main pipe 11 is connected to a branch pipe 12, and a nozzle 6 is installed on the branch pipe 12.

[0012] This invention adds a piston booster device, which can increase the air pressure inside the main pipe 11 when needed, thereby improving the dust blowing effect of the nozzle 6 and improving the dust cleaning effect.

[0013] Specific material selection and feasibility analysis: The samples we actually produced used the attached drawings in the instruction manual as the blueprints, and were implemented according to the proportions and assembly methods of each component in the drawings. The connections used were common methods such as strong adhesive bonding, welding, riveting, flange connections, and one-piece molding connections. In actual production, the corresponding connection method, thickness, and strength of the connection points can be selected according to the actual connection strength requirements without creative innovation. During routine soot blowing operations, the second valve 9 is closed and the third valve 10 is open. At this time, the air source 1 inputs gas into the main pipe 2, the header pipe 11, the branch pipe 12, and the nozzle 6 for routine soot blowing operations. When the dust inside the boiler is difficult to clean and the routine soot blowing effect is not good, the first valve 7 and the air pump 8 can be opened simultaneously with the second valve 9 closed and the third valve 10 open. The air pump 8... Figure 1 Gas is introduced into piston cylinder 4 of the status chamber. After piston cylinder 4 is fully inflated, the first valve 7 can be closed, and then the hydraulic jack 3 can be activated to push piston 5 to apply secondary pressure to piston cylinder 4, achieving the desired pressure. Figure 2 In this state, the pressure is increased. At this point, the outlet of the first valve 7 is no longer located in the pressurized space inside the piston cylinder 4. Then, the gas source 1 and the third valve 10 are closed, and the second valve 9 is opened. At this time, the high-pressure gas inside the piston cylinder 4 enters the main pipe 11, the branch pipe 12, and the nozzle 6, allowing the nozzle 6 to blow at a higher pressure onto the strongly adhered dust inside the boiler, thereby improving the dust cleaning effect. The internal gas pressure involved in this device should not exceed the maximum withstand pressure of this device.
