Description

Technical Field

[0001] The utility model relates to the technical field of gas soot blowers, in particular to a gas soot blower with a "F"-shaped branch distribution control. Background Art

[0002] Ash and coking in the boiler is an unavoidable problem when using the boiler. Because in the process of coal powder combustion, in addition to a part of the product discharged from the slag outlet, the remaining part that is not fully burned will cool, adsorb, and adhere on the heat exchange surface, forming coke and ash accumulation, which will increase the thermal resistance of the heat exchange surface and reduce the thermal efficiency. During the operation of the boiler, by equipping the heat exchange surface with a soot blower to purge the heat exchange surface, it can better prevent the coking, ash accumulation and corrosion of the heat exchange surface of the boiler, ensure the safe operation of the boiler, and improve the efficiency of the boiler.

[0003] At present, the commonly used types of boiler soot blowers on the market include sonic soot blowers, air soot blowers, steam soot blowers and gas soot blowers. Gas soot blowers are also called shock wave soot blowers, acetylene soot blowers, shock wave soot blowers, explosion wave soot blowers, etc. The main working principle of gas soot blowers is to use gas and air as gas sources, mix air and gas in a certain proportion, and then explode in a special container. The generated shock wave acts on the heat exchange surface, and the accumulated ash on the heat exchange surface tube bundle is peeled off and falls off by blowing, acoustic fatigue, thermal cleaning and other methods. Gas soot blowers are widely promoted and used due to their advantages such as strong soot blowing force, large soot blowing range, large application surface and low equipment cost.

[0004] However, the current gas soot blower adopts a one-belt-two modular distribution form, inflating two pulse gas tanks at the same time, and simultaneously deflagrating. The two pulse gas tanks are connected, and there is a problem of uneven inflation of the two pulse gas tanks. Moreover, since the two pulse gas tanks are connected to the inside of the boiler at the same time, the pressure difference in the boiler is different during boiler operation, and a pressure difference will be generated between the two pulse gas tanks, causing the flue gas to flow back into the pulse gas tanks and the inside of the pipeline, resulting in corrosion of the equipment and pipelines, posing a great hidden danger to the service life and safety of the equipment.

[0040] The following further elaborates on the present utility model in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are merely for explaining the present utility model and not for limiting it. Additionally, it should be noted that for the sake of description, only the parts related to the present utility model rather than all the structures are shown in the drawings.

[0041] In the description of the present utility model, unless otherwise clearly specified and defined, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above - mentioned terms in the present utility model can be understood according to specific circumstances.

[0042] The present utility model provides a gas soot blower with a cross - shaped branch distribution control, as Figure 1 shown. This gas soot blower with a cross - shaped branch distribution control includes a mixing tank 4, a gas supply device 1, a gas regulating device 2, an air supply device, an air regulating device 3, an ignition device 5, a plurality of branch control devices 6, and a plurality of pulse gas storage tanks 7. The gas supply device 1 is connected to the first inlet of the mixing tank 4 through the gas regulating device 2. The air supply device is connected to the second inlet of the mixing tank 4 through the air regulating device 3. The ignition device 5 is connected to the outlet of the mixing tank 4. A plurality of branch control devices 6 are all connected to the ignition device 5, and a plurality of branch control devices 6 and a plurality of pulse gas storage tanks 7 are connected in one - to - one correspondence.

[0043] In this cross-shaped branch distribution control gas soot blower, the gas supply device 1 is used to supply gas. The gas supplied by the gas supply device 1 enters the mixing tank 4 after being regulated by the gas regulating device 2. The air supply device is used to supply air. The air supplied by the air supply device enters the mixing tank 4 after being regulated by the air regulating device 3. The air and gas are mixed in the mixing tank 4 to form a mixed gas. The mixed gas passes through the ignition device 5 and then enters the pulse gas storage tanks 7 on each branch through the branch control device 6 on each branch. The branch control device 6 is used to control the connection or disconnection between the ignition device 5 and the pulse gas storage tank 7. When the ignition device 5 ignites, the mixed gas in the pipeline between the ignition device 5 and the branch control device 6 and the mixed gas in the pipeline between the branch control device 6 and the pulse gas storage tank 7 will be ignited. The formed fuse will then ignite the mixed gas in the pulse gas storage tank 7, thereby forming a shock wave and rushing into the boiler. In this cross-shaped branch distribution control gas soot blower, a branch control device 6 is provided on each branch, and one branch control device 6 corresponds to one pulse gas storage tank 7, which can respectively control the intake of each pulse gas storage tank 7 and respectively ignite the mixed gas in each pulse gas storage tank 7. Thus, the mixed gas in two or more pulse gas storage tanks 7 will not be ignited simultaneously, and two or more pulse gas storage tanks 7 will not be connected to the boiler at the same time, which can prevent the flue gas from flowing back into the pulse gas storage tank 7 and the pipeline interior, prevent the flue gas from corroding the equipment and pipeline, improve the service life and safety level of the equipment, and can ensure that the mixed gas is evenly filled into the pulse gas storage tank 7, improve the deflagration effect of the mixed gas, and thus improve the soot blowing effect.

[0044] It can be understood that the pulse gas storage tank 7 is provided with a pulse nozzle, and the pulse nozzle is connected to the inside of the boiler. When the mixed gas is filled into the pulse gas storage tank 7 but has not reached the pulse nozzle, the mixed gas is ignited, and the shock wave enters the boiler interior from the pulse nozzle.

[0045] Optionally, as Figure 2 shown, the branch control device 6 includes a branch independent control unit 62 and a pneumatic valve 61. The pneumatic valve 61 is respectively connected to the ignition device 5 and the pulse gas storage tank 7. The branch independent control unit 62 can control the connection or disconnection of the pneumatic valve 61. This cross-shaped branch distribution control gas soot blower uses the pneumatic valve 61 to control the on-off of the pipeline between the pulse gas storage tank 7 and the ignition device 5, with tight sealing, so that there will be no pressure difference between the boiler during operation and the pulse gas storage tank 7 and each pipeline, preventing the flue gas in the boiler from entering the pulse gas storage tank 7 and the pipeline, and can solve the problem of the mixed gas leaking into the boiler. Compared with the rotating header type sealing structure, it solves the problem of poor sealing between the rotating header rotor and the base and large air leakage. Compared with the sealing structure using solenoid valves, it avoids the situation of poor sealing after the solenoid valves are used for a period of time.

[0046] In this embodiment, the internal section of the pneumatic valve 61 adopts a knife-shaped edge design, which makes the seal more tight.

[0047] Alternatively, if Figure 3 As shown, the gas supply device 1 includes a gas manifold 12 and a plurality of gas bottles 11, wherein the plurality of gas bottles 11 are connected to one end of the gas manifold 12, and the other end of the gas manifold 12 is connected to the gas regulating device 2, and a pressure reducing valve 13 is provided at the outlet of the plurality of gas bottles 11. A plurality of gas bottles 11 are used for gas supply, and the gas pressure can be regulated separately by the pressure reducing valve 13. If a pressure reducing valve 13 fails or the gas bottle 11 needs to be replaced, other gas bottles 11 can be used for gas supply first, and the boiler can be soot-blown uninterruptedly when the pressure reducing valve 13 or the gas bottle 11 is replaced, without affecting the boiler production. Moreover, if a backfire failure occurs, the gas in the gas manifold 12 is ignited, and it needs to spread to the gas bottle 11 through multiple pipelines, which can disperse the flame and cool the flame, thereby improving the fire-retardant ability and safety.

[0048] Optionally, an exhaust valve 15 is provided at one end of the gas manifold 12 connected to the gas regulating device 2. When the output pressure of the gas bottle 11 is adjusted by the pressure reducing valve 13, if the pressure in the gas manifold 12 is too high, the exhaust valve 15 can be used to release it.

[0049] In this embodiment, the number of gas cylinders 11 is three.

[0050] Optionally, a flashback 14 is provided on the pipeline between the plurality of pressure reducing valves 13 and the gas manifold 12. Each gas cylinder 11 is provided with a flashback 14, which can realize a separate fire-blocking function and further improve safety.

[0051] When in use, first manually fully open the switch of a gas bottle 11, and then adjust the gas output pressure to the pressure required by the equipment through the pressure reducing valve 13. At this time, the gas will flow through the temperer 14, and then enter the gas manifold 12 through the metal braided hose, and so on. After all three gas bottles 11 are opened and the pressure reduction is adjusted, the gas supply device 1 completes the operation.

[0052] Alternatively, if Figure 4 As shown, the gas regulating device 2 includes a gas wafer ball valve 21, a pressure gauge 22, a ball valve with a dial 23 and an explosion-proof solenoid valve 24. The gas supply device 1 is connected to the gas wafer ball valve 21, and the gas wafer ball valve 21, the pressure gauge 22, the ball valve with a dial 23 and the explosion-proof solenoid valve 24 are connected in sequence. The explosion-proof solenoid valve 24 is connected to the mixing tank 4.

[0053] The pressure gauge 22 is installed on the pipeline between the gas clamp ball valve 21 and the ball valve with a dial 23 through the source component to detect the pressure. The gas provided by the gas supply device 1 passes through the gas clamp ball valve 21, and the pressure is displayed on the pressure gauge 22, which is convenient for the operator to detect whether the gas output pressure meets the use requirements at any time and anywhere. When the explosion-proof solenoid valve 24 and the pneumatic valve 61 are opened, the ball valve with a dial 23 is used to adjust the gas flow at this time. It is easy to operate and can simply and quickly adjust the gas flow. The explosion-proof solenoid valve 24 can connect or disconnect the pipeline between the gas supply device 1 and the mixing tank 4.

[0054] Optionally, the gas regulating device 2 further comprises a flame arrester 25, which is arranged on the pipeline between the explosion-proof solenoid valve 24 and the mixing tank 4. The flame arrester 25 can prevent the flame from spreading and improve safety.

[0055] Optionally, the gas regulating device 2 further comprises a gas one-way check valve 26, which is disposed at the first inlet of the mixing tank 4. The gas one-way check valve 26 can prevent the mixed gas in the mixing tank 4 from flowing back into the gas regulating device 2.

[0056] Optionally, the Feng-shaped branch distribution control gas soot blower further includes a mixed gas one-way check valve 9, which is arranged at the outlet of the mixing tank 4. The mixed gas one-way check valve 9 can prevent the mixed gas from flowing back to the gas regulating device 2 and the air regulating device 3 after explosion.

[0057] Optionally, the air conditioning device 3 includes an air sandwich ball valve 31, an air pressure reducing filter duplex 32, an air solenoid valve 33 and a throttling orifice plate 34, the air supply device is connected to the air sandwich ball valve 31, the air sandwich ball valve 31, the air pressure reducing filter duplex 32, the air solenoid valve 33 and the throttling orifice plate 34 are connected in sequence, and the throttling orifice plate 34 is connected in sequence to the mixing tank 4. The throttling orifice plate 34 can control the flow of air to make the flow of air fixed, the air sandwich ball valve 31 and the air pressure reducing filter duplex 32 filter and reduce the pressure of air, and the air solenoid valve 33 is turned on and off to realize the air distribution function. After the pipeline between the mixing tank 4 and the ignition device 5 is filled with the mixed gas, the explosion-proof solenoid valve 24 will be closed to prevent the introduction of gas, and a section of air will be introduced again. The introduced air forms an air column in the pipeline, but it is necessary to ensure that the introduced air column does not exceed the ignition device 5. The purpose is that the air column can buffer the recoil force generated by the explosion of the mixed gas to a certain extent, protect the mixed gas one-way check valve 9 from being impacted by the strong explosion recoil force, extend its service life, and at the same time have fire-blocking and anti-backfire protection functions.

[0058] Alternatively, if Figure 1-4As shown, the cross-shaped branch distribution control gas soot blower further includes a PLC program control cabinet 8, and the gas regulating device 2, the air regulating device 3, the ignition device 5 and the branch control device 6 are all electrically connected to the PLC program control cabinet 8. It can be understood that the gas regulating device 2, the air regulating device 3, the ignition device 5 and the branch control device 6 are all electrically connected to the PLC program control cabinet 8 through cables.

[0059] Specifically, the branch independent control unit 62, the air solenoid valve 33, the explosion-proof solenoid valve 24 and the ignition device 5 are all electrically connected to the PLC program control cabinet 8, and the PLC program control cabinet 8 can control the on-off of the air solenoid valve 33 and the explosion-proof solenoid valve 24 and control the branch independent control unit 62 to make the pneumatic valve 61 on-off.

[0060] Optionally, the mixing tank 4 is provided with a drain valve 41. If there is water accumulation due to condensation in the mixing tank 4, it can be discharged through the drain valve 41.
