[0037] Embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0038] At present, most of the coal-fired power plants in my country use a lot of slagging coal. In addition, the quality of coal used in power plants in my country varies greatly, often deviating from the design value. Therefore, there are varying degrees of slagging and ash accumulation on the heating surface of the boiler. Slagging and ash accumulation on the heating surface of the boiler may affect the heat transfer and normal operation of the boiler, or even lead to load reduction or even shutdown, seriously affecting the safety and economy of boiler operation.

[0039] In order to reduce the impact of boiler slagging and ash accumulation, in the related art, a soot blower is usually used to remove the slagging and ash accumulation on the boiler heating surface. However, due to the unreasonable drainage method of the soot blower and the incomplete drainage, the water-cooled wall of the boiler is easily damaged.

[0040] In order to solve the defects in the related art, the solution provided by the present disclosure is that when the drain valve of the sootblower is opened to drain, the drain temperature is obtained, and when the drain temperature reaches a preset first temperature, the main air inlet valve of the sootblower is closed to reduce the flow of steam in the gas source through the sootblower, so that the water vapor that has not been completely drained in the pipeline is condensed again and drained smoothly; after the first period of time, the drainage in the sootblower pipeline can be completely completed, at which time the main air inlet valve can be opened, the drain valve can be closed, and the sootblower can continue to be used to clean the boiler. The present disclosure is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] like Figure 1 As shown, Figure 1 A flow chart of a boiler sootblower draining method provided in an embodiment of the present disclosure. The boiler sootblower draining method provided in an embodiment of the present disclosure is applied to a boiler sootblowing system, specifically, to a master controller of a boiler sootblowing system; the boiler sootblowing system comprises at least one first sootblower and at least one second sootblower, the air sources of the at least one first sootblower and the at least one second sootblower are the same and are controlled by an incoming air main gate, each of the first sootblower and each of the second sootblower is provided with a drain gate for draining, the first sootblower is used for sootblowing the air preheater of the boiler, and the second sootblower is used for sootblowing the boiler; the boiler sootblower draining method provided in an embodiment of the present disclosure comprises the following steps:

[0042] Step 101, in response to receiving a first opening signal of the drain door of the third sootblower in the second sootblower, obtaining a drain temperature;

[0043] In one embodiment, the third sootblower is any one of the second sootblowers, that is, the third sootblower is used for sootblowing the boiler.

[0044] In one embodiment, the drain valve of the third sootblower is opened, which means that the third sootblower starts draining. The electronic switches of the main air inlet valve, the drain valves of each first sootblower and each second sootblower, such as solenoid valves, are all connected to the main controller of the boiler sootblowing system, so that the main controller can determine whether the corresponding drain valve and / or the main air inlet valve is opened or closed according to the signal of the electronic switch.

[0045] In one embodiment, the drain temperature can be collected by a temperature sensor disposed at the drain gate, and the temperature sensor is connected to a signal input terminal of the main controller so that the main controller can obtain the drain temperature.

[0046] Step 102, in response to the drain temperature reaching a first temperature, issuing a first closing instruction to the main air inlet valve, and starting a first timing;

[0047] In one embodiment, the first closing instruction is used to close the main air inlet valve;

[0048] In one embodiment, the first temperature refers to the temperature at which the water vapor in the sootblower pipe can be quickly condensed. The first temperature can be obtained from historical experience values. For example, the first temperature can be 175 degrees, etc., which is not limited in the present disclosure.

[0049] In one embodiment, after the drain temperature reaches the first temperature, the main air valve is closed by issuing a first closing command to the main air valve to prevent new moisture in the air source from entering the third soot blower, and at the same time, the water vapor in the pipeline of the third soot blower is quickly condensed and discharged from the drain valve to successfully drain the moisture in the pipeline of the third soot blower.

[0050] In one embodiment, the first closing instruction can trigger the electronic switch of the main air inlet valve to close.

[0051] Step 103 , in response to the first timing reaching a first duration, issuing a first opening instruction to the incoming air main valve, and issuing a second closing instruction to the drain valve of the third sootblower.

[0052] In one embodiment, the first opening instruction is used to open the main air inlet valve, and the second closing instruction is used to close the drain valve of the third sootblower.

[0053] In one embodiment, the first time period refers to the time period during which the moisture in the sootblower pipe can be drained after the drain temperature reaches the first temperature and the main air inlet valve is closed; wherein the first time period can be obtained from historical experience values.

[0054] In one embodiment, after the first timing reaches the first time length, it indicates that the moisture in the pipeline of the third sootblower has been drained. At this time, a first opening instruction can be issued to the main air inlet valve, and the main air inlet valve triggers the main air inlet valve to open in response to the first opening instruction, so that the third sootblower can continue to perform sootblowing work on the boiler normally. At the same time, the drain valve of the third sootblower is closed by issuing a second closing instruction to the drain valve of the third sootblower.

[0055] In summary, the present disclosure proposes a boiler sootblower draining method, which is applied to a boiler sootblowing system, wherein the boiler sootblowing system includes at least one first sootblower and at least one second sootblower, the gas sources of the at least one first sootblower and the at least one second sootblower are the same and are controlled by an incoming air main gate, each of the first sootblower and each of the second sootblower is provided with a drain gate for draining, the first sootblower is used for sootblowing an air preheater of a boiler, and the second sootblower is used for sootblowing a boiler; the method includes: in response to receiving a first opening signal of the drain gate of a third sootblower in the second sootblower, obtaining a drain temperature; in response to the drain temperature reaching a first temperature, issuing a first closing instruction to the incoming air main gate and starting a first timing; the first closing instruction is used to close the incoming air main gate; in response to the first timing reaching a first duration, issuing a first opening instruction to the incoming air main gate, and issuing a second closing instruction to the drain gate of the third sootblower; the first opening instruction is used to open the incoming air main gate, and the second closing instruction is used to close the drain gate of the third sootblower.

[0056] The solution provided by the present disclosure is that when the drain valve of the soot blower is opened to start draining, the drain temperature is obtained, and when the drain temperature reaches a preset first temperature, the main air inlet valve of the soot blower is closed to reduce the flow of steam in the air source passing through the soot blower, so that the water vapor that has not been completely drained in the pipeline is condensed again and drained smoothly; after the first period of time, the draining in the soot blower pipeline can be completely completed, and at this time the main air inlet valve can be opened, the drain valve can be closed, and the soot blower can continue to be used to clean the boiler.

[0057] In one embodiment, if Figure 2 As shown, after the first opening instruction is issued to the main air inlet valve in step 103, the boiler sootblower draining method provided by the present disclosure further includes:

[0058] Step 201, in response to receiving a first pause signal, starting a second timing; the first pause signal is used to indicate that the third sootblower starts a pause state;

[0059] In one embodiment, the third soot blower may be suspended due to a mechanical failure, but according to the setting of the main controller, the third soot blower should automatically restart within fifteen minutes after being suspended; if the third soot blower does not automatically restart within fifteen minutes, it means that the third soot blower is faulty. At this time, the main air door should be closed and the third soot blower should be inspected and repaired.

[0060] Step 202, in response to the second timing reaching a second duration, if the first restart signal is not received, a third closing instruction is sent to the main air inlet valve.

[0061] In one embodiment, the first restart signal is used to instruct the third sootblower to restart from a pause state, and the third closing instruction is used to close the main air inlet door.

[0062] In one embodiment, the boiler sootblower draining method provided by the present disclosure further includes:

[0063] In response to receiving the second opening signal, a first stop instruction is sent to the third soot blower, and a fourth closing instruction is sent to the main air inlet valve.

[0064] In one embodiment, the second start signal is used to instruct the first soot blower to start working, the first stop instruction shuts down the third soot blower, and the third closing instruction is used to close the main air inlet valve.

[0065] In one embodiment, since the first soot blower is used to blow soot on the air preheater of the boiler, and the first soot blower is located at the lowest point of all soot blowers, when the first soot blower is working, the second soot blower used for soot blowing on the boiler should stop working. Therefore, in response to receiving the second opening signal, a first stop command is sent to the third soot blower, and a fourth closing command is sent to the main air inlet gate.

[0066] In one embodiment, since the first sootblower is at the lowest point of all sootblowers, a large amount of water will gather at the first sootblower when other sootblower are in operation. Therefore, the first sootblower needs to be drained again when it is working to reduce the blowing damage to the heat transfer element of the air preheater.

[0067] Based on this, in one embodiment, after the fourth closing instruction is issued to the main air inlet valve, the boiler sootblower draining method provided by the present disclosure further includes:

[0068] issuing a second opening instruction to the drain door of the third sootblower, and starting a third timing; the second opening instruction is used to open the drain door of the third sootblower;

[0070] In one embodiment, the third time period refers to the time period during which the moisture in the pipeline of the third sootblower can be drained when the third sootblower is turned on. When the third timing reaches the third time period, it means that the first sootblower located at the lowest point of all the sootblowers has completed the drainage. At this time, the drain gate of the third sootblower can be closed by issuing a fifth closing instruction to the drain gate of the third sootblower.

[0071] In one embodiment, in response to receiving the second start signal, the boiler sootblower draining method provided by the present disclosure further includes:

[0072] If a third start signal of the fourth sootblower among the second sootblower is received, a first prompt is issued; the first prompt is used to prompt prohibition of starting other second sootblower except the third sootblower and the fourth sootblower.

[0073] In one embodiment, reducing the number of sootblowing times can also effectively protect the boiler. Therefore, under normal circumstances, at most two second sootblowers are allowed to sootblow the boiler, such as the third sootblowers and the fourth sootblowers. At this time, if two second sootblowers have been turned on in the boiler sootblowing system, other sootblowers should be prohibited from turning on.

[0074] In one embodiment, the boiler sootblower draining method provided by the present disclosure further includes:

[0075] Obtain the coking information of the water-cooled wall of the boiler. If the coking information indicates that the coking of the water-cooled wall is not serious, send a second stop instruction to the third soot blower or the fourth soot blower; the second stop instruction is used to shut down the third soot blower or the fourth soot blower that receives the second stop instruction.

[0076] In one embodiment, if the coking of the water-cooled wall of the boiler is not serious, a single-blowing working mode of a second sootblower may be adopted; if the coking of the water-cooled wall of the boiler is serious, a counter-blowing working mode of two second sootblower may be adopted.
