Description

Technical Field

[0001] The invention relates to the technical field of entrained-bed coal gasification, and in particular to a control method and device for starting a gasifier. Background Art

[0002] Before coal is added to the gasifier, the furnace temperature must be raised to a level sufficient to ignite coal powder or coal slurry through the combustion of fuel gas. Therefore, there is an ignition and start-up process before coal is added. Ignition is to form a small flame in the furnace to ignite the fuel gas and oxygen introduced in the next step; start-up is the process of fuel gas burning and heating in the furnace. Ignition only uses a small amount of fuel gas and combustion-supporting air. After successful ignition, a larger amount of fuel gas and combustion-supporting oxygen is introduced to start the "start-up" process.

[0003] However, during the process from ignition to start-up, the flame may go out due to excessive gas volume or an improper ratio of oxygen to fuel gas, which may lead to start-up failure. At this time, the oxygen content in the furnace space is high due to the oxygen introduced during the start-up, and it is necessary to start purge to replace the residual gas with an inert environment before preparing for the next ignition, otherwise it is easy to cause a flash explosion. The exhaust gas from the entire start-up process is discharged to the flare system, but the oxygen content of the replaced exhaust gas in the start-up failure condition may exceed the oxygen content limit (0.5v%) required by the flare system, and the risk of flare discharge is relatively high.

[0041] The embodiment of the present invention provides a control method and device for starting a gasifier, which is used to vent the high point of the generated gas when a start-up failure occurs and isolate it from the flare system, completely solving the problem of the safe destination of the replacement gas in the event of a start-up failure.

[0042] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] For example, see Figure 1 , Figure 1 The present invention is a flow chart of a control method for starting a gasifier according to a first embodiment of the present invention, which is applied to a gasifier start-up control system. The system is provided with a vent valve that discharges directly to the atmosphere and is located at a high point of the system, and a flare valve of a flare system. The method comprises:

[0044] Step S101, obtaining the start-up flame information, start-up duration and start-up operation duration;

[0045] Step S102, determining the start-up working condition of the gasifier according to the start-up time, the start-up flame information and the start-up operation time;

[0046] Step S103, when the start-up condition is a successful start-up condition, using the synthesis gas space pressure, the generated gas is sent to the flare system through the flare valve;

[0047] Step S104, when the start-up condition is a start-up failure condition, the generated gas is discharged into the atmosphere through the vent valve using the synthesis gas space pressure.

[0048] A control method for starting a gasifier provided in an embodiment of the present invention is applied to a gasifier start-up control system, wherein the system is provided with a vent valve that discharges directly to the atmosphere and is located at a high point of the system, and a flare vent valve of a flare vent system; the method comprises: obtaining start-up flame information, start-up duration, and start-up operation duration; determining the start-up working condition of the gasifier according to the start-up duration, the start-up flame information, and the start-up operation duration; when the start-up working condition is a successful start-up working condition, the generated gas is sent to the flare system through the flare vent valve by utilizing the synthesis gas space pressure; when the start-up working condition is a failed start-up working condition, the generated gas is discharged to the atmosphere through the vent valve by utilizing the synthesis gas space pressure. The start-up state of the gasifier is judged by the start-up flame information, the start-up duration, and the start-up operation duration, and by providing a vent valve located at a high point of the system, the high point of the generated gas is vented when the start-up failure condition occurs, and it is isolated from the flare system, which completely solves the problem of the safe destination of the replacement gas in the failed start-up.

[0049] For example 2, please refer to Figure 2 , Figure 2 This is a flow chart of a second embodiment of a control method for starting a gasifier according to the present invention, which is applied to a gasifier start-up control system. The system is provided with a vent valve PV01C for directly discharging to the atmosphere, a downstream valve PV01A connected to a downstream device, and a flare valve PV01B connected to a flare system. The method includes:

[0050] Step S201, obtaining the start-up flame information, start-up duration and start-up operation duration;

[0051] The embodiment of the present invention is applied to Figure 3 The gasifier start-up control system shown in the figure can avoid the excessive oxygen content of the gasifier start-up torch gas, wherein the top of the gasifier 1 is an integrated burner 11, through which the fuel gas and air can be ignited, the fuel gas and oxygen can be started to heat up, and when the temperature in the furnace is sufficient, coal and oxygen can be added. The gasifier 1 is divided into two chambers, the upper chamber is the reaction chamber 12, and the lower chamber is the quenching chamber 13. The synthesis gas generated in the reaction chamber 12 is quenched in the quenching chamber 13 and then initially purified downstream (water washing tower 2, etc.), and then has three destinations: (1) sent downstream through the downstream valve PV01A; (2) discharged after the flare is burned through the flare valve PV01B; (3) directly released through the high point of the vent valve PV01C.

[0052] At the same time, the system can avoid the oxygen content of the gasifier startup flare gas being too high, and is equipped with two timers, namely, a startup timer and a startup operation timer. The startup timer is provided with a startup threshold, and the startup timer starts timing when the startup fuel gas and startup oxygen are introduced to obtain the startup time; the startup operation timer is provided with a startup operation threshold, and the startup operation timer starts timing when the startup flame appears, and records the startup operation time.

[0053] In addition, in order to monitor the combustion state of the flame, a flame monitor XT01 is installed on the dome of the reaction chamber 12 of the gasifier 1. The entire space from the gasifier 1 through the pipeline to the water washing tower 2 and then from the pipeline to the boundary area is called the synthesis gas space. A pressure gauge PT01 is installed in the pipeline out of the water washing tower 2, which cooperates with the vent valve PV01C, the downstream valve PV01A and the flare valve PV01B to control the pressure of the synthesis gas space, wherein the downstream valve PV01A is not used during the start-up process; and a gas production destination control unit 3 with a start-stop program is installed, which introduces flame detection signals, synthesis gas space pressure signals and system important valve status signals to automatically judge the state of the system, thereby automatically selecting a suitable synthesis gas destination.

[0054] Step S202, determining whether the start-up time is greater than a preset start-up threshold, and whether the start-up flame information is that the start-up flame does not appear, if so, determining that the start-up condition is the start-up failure condition, and executing step S206;

[0055] Step S203, judging whether the start-up operation time is less than a preset start-up operation threshold, and whether the start-up flame information is that the flame disappears after the start-up, if so, determining that the start-up condition is the start-up failure condition, and executing step S206;

[0056] Step S204, judging whether the start-up operation time is greater than or equal to the start-up operation threshold, and whether the start-up flame information is the start-up flame appearing, if so, determining that the start-up condition is the start-up success condition, and executing step S207;

[0057] Step S205, judging whether the start-up operation time is greater than or equal to the start-up operation threshold, and whether the start-up flame information is that the start-up flame disappears, if so, determining that the start-up operating condition is the start-up stop operating condition, and executing step S208;

[0058] Step S206, when the start-up condition is a start-up failure condition, using the synthesis gas space pressure to release the generated gas to the atmosphere through the release valve;

[0059] Step S207, when the start-up condition is a successful start-up condition, using the synthesis gas space pressure, the generated gas is sent to the flare system through the flare valve;

[0060] Step S208, when the start-up condition is the start-up and shutdown condition, the synthesis gas air pressure is used to send the generated gas to the flare system through the flare valve.

[0061] In the embodiment of the present invention, the system that can prevent the oxygen content of the flare gas from being too high when the gasifier is started has three operating modes:

[0062] (1) When the operation is successfully started, the flare valve PV01B discharges the generated gas to the flare system. Specifically, the flare valve PV01B is controlled by the syngas pressure through PT01 under the control of the gas production destination control unit 3. The specific judgment process is: when the start-up time exceeds the start-up threshold, the start-up flame appears, and it can be determined that the gasifier 1 has been successfully started;

[0063] (2) When the gasifier is in the start-up and shutdown condition, the flare valve PV01B discharges the generated waste gas to the flare system. Specifically, under the control of the gas production destination control unit 3, the synthesis gas pressure control is used to control the flare valve PV01B through PT01. The specific judgment process is as follows: if the running time of the start-up operation timer is greater than or equal to the start-up operation threshold, and the start-up flame disappears after it appears, it can be determined that the start-up condition of the gasifier 1 is the start-up and shutdown condition, rather than the start-up failure condition. At this time, the combustion in the furnace is relatively sufficient, and the waste gas is discharged to the flare system for treatment.

[0064] (3) When in the start-up failure condition, the vent valve PV01C discharges the generated gas into the atmosphere, specifically: under the control of the gas production destination control unit 3, the downstream valve PV01A connected to the downstream device and the flare valve PV01B connected to the flare system are closed, and the vent valve PV01C is controlled by the synthesis gas pressure at the same time; the specific judgment process is: if the start-up time exceeds the start-up threshold and the start-up flame does not appear, it is determined that the gasifier 1 has not completed the start-up task within the specified time, and it is determined to be a start-up failure condition; and if the start-up operation time is less than the start-up operation threshold and the start-up flame disappears, it can be determined that the initial start-up was successful, but it did not run for a long enough time. It may be that the flame is unstable and the combustion state is poor. At this time, the oxygen content may still exceed the standard, so it can be determined that the gasifier 1 is in a start-up failure condition.

[0065] A control method for starting a gasifier provided in an embodiment of the present invention is applied to a gasifier start-up control system, wherein the system is provided with a vent valve for directly discharging to the atmosphere, a flare valve for discharging a flare system, and a downstream valve connected to a downstream device, wherein the downstream valve is not used during the start-up process; comprising: obtaining start-up flame information, start-up duration, and start-up operation duration; determining the start-up working condition of the gasifier according to the start-up duration, the start-up flame information, and the start-up operation duration; when the start-up working condition is a successful start-up working condition, the synthesis gas space pressure is used to send the generated synthesis gas to the flare system through the flare valve; when the start-up working condition is a failed start-up working condition, the synthesis gas space pressure is used to discharge the generated gas to the atmosphere through the vent valve. The start-up state of the gasifier is judged by the start-up flame information, the start-up duration, and the start-up operation duration, and by setting a vent valve at the high point of the system, the high point of the generated gas is vented when the start-up failure condition occurs, and it is isolated from the flare system, which completely solves the problem of the safe destination of the replacement gas in the failed start-up.
