Description

Technical Field

[0001] The invention relates to the technical field of air door control in a thermal power plant, and in particular to a method and a device for determining the opening of an air door in a thermal power plant. Background Art

[0002] The damper (baffle) is an indispensable component in the wind system of a thermal power plant. Its structure is generally a shutter type, and the power plant operator controls the air volume or flue gas flow by adjusting the angle of the damper blade. Usually, the damper is the first thing to control the operation of the unit. In order to better understand and control the operation of the unit, the damper opening will be displayed on the computer-side unit operation screen, so that the operator can open and close the damper or adjust its blade closing angle in time. Therefore, the angle displayed in the unit operation screen needs to be consistent with the actual angle of the blade. However, for some automatically adjusted dampers (such as cold and hot air dampers of coal mills) or dampers in harsh environments (such as dampers in flues), it is very easy for the angle displayed in the unit operation screen to be inconsistent with the actual angle of the blade, so it is necessary to regularly check the blade angle. The method of verification is usually that the operator is in front of the unit operation screen, and the maintenance personnel are on site, and the two cooperate to adjust the actual angle of the blade to be consistent with the screen display.

[0042] The embodiment of the present invention provides a method and device for determining the opening of a damper in a thermal power plant.

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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.

[0044] like Figure 1 The flowchart of a method for determining the air damper opening in a thermal power plant according to an embodiment of the present invention is shown. The execution subject of the method for determining the air damper opening in a thermal power plant provided by the embodiment of the present invention includes but is not limited to a computer. The method shown in the figure includes:

[0045] Step S1, using an electronic inclination measuring instrument to obtain the upper surface inclination angle, the lower surface inclination angle, the front inclination angle of the damper, and the rear inclination angle of the damper of the air flow channel of the boiler;

[0046] Step S2, determining the inclination angle of the airflow direction according to the inclination angle of the upper surface and the inclination angle of the lower surface of the airflow channel;

[0047] Step S3, determining the inclination angle of the damper according to the front inclination angle of the damper and the rear inclination angle of the damper;

[0048] Step S4, determining the angle between the damper and the airflow direction according to the airflow direction inclination angle and the damper inclination angle, and using the angle as the damper opening in the thermal power plant.

[0049] Among them, the damper refers to the damper installed in the air duct or flue in the thermal power plant to intercept the air or flue gas. Usually the damper opening and closing angle ranges from 0° to 90°, and the air or flue gas volume is controlled by adjusting the damper opening. The inclination angle of the airflow direction refers to the angle between the airflow velocity direction and the horizontal plane. The inclination angle of the damper refers to the angle between the damper and the horizontal plane. The opening of the damper refers to the angle between the damper and the airflow direction.

[0050] Before the measurement, it is necessary to calibrate the electronic inclinometer, and use the electronic inclinometer to measure the inclination angle of the upper surface and the inclination angle of the lower surface of the airflow channel respectively.

[0051] Furthermore, the airflow direction inclination angle is calculated according to the upper surface inclination angle and the lower surface inclination angle of the flow channel. Specifically, the sum of the upper surface inclination angle and the lower surface inclination angle is calculated, and the sum is divided by 2 to obtain the airflow direction inclination angle.

[0052] Furthermore, an electronic inclinometer is used to measure the front inclination angle of the damper and the rear inclination angle of the damper respectively, and the sum of the front inclination angle of the damper and the rear inclination angle of the damper is calculated. The sum is divided by 2 to obtain the damper inclination angle.

[0053] Furthermore, the absolute value of the difference between the airflow direction inclination angle and the damper inclination angle is calculated, and the absolute value is the angle between the damper and the airflow direction, that is, the damper opening in the thermal power plant. After accurately calculating the damper opening in the thermal power plant, problems such as primary and secondary air volume deviation and flame center deviation that reduce the unit's operating efficiency and stability can be avoided, allowing operating personnel to better understand and control unit operations, saving labor costs and improving economic efficiency.

[0054] As an embodiment of the present invention, Figure 2 As shown, according to the inclination angle of the upper surface and the lower surface of the airflow channel, determining the inclination angle of the airflow direction includes:

[0055] Step S21, determining the sum of the upper surface inclination angle and the lower surface inclination angle of the airflow channel according to the upper surface inclination angle and the lower surface inclination angle of the airflow channel;

[0056] Step S22, determining the inclination angle of the airflow direction according to the sum of the inclination angle of the upper surface and the inclination angle of the lower surface of the airflow channel.

[0057] The airflow direction inclination angle is calculated according to the inclination angles of the upper surface and the lower surface of the flow channel. Specifically, the sum of the upper surface inclination angle and the lower surface inclination angle is calculated, and the sum is divided by 2 to obtain the airflow direction inclination angle.

[0058] As an embodiment of the present invention, Figure 3 As shown, according to the front inclination angle of the damper and the reverse inclination angle of the damper, determining the damper inclination angle includes:

[0059] Step S31, determining the sum of the front inclination angle of the damper and the rear inclination angle of the damper according to the front inclination angle of the damper and the rear inclination angle of the damper;

[0060] Step S32, determining the damper inclination angle according to the sum of the damper front inclination angle and the damper rear inclination angle.

[0061] The front and rear inclination angles of the damper are measured by an electronic inclinometer, and the sum of the front and rear inclination angles of the damper is calculated. The sum is divided by 2 to obtain the damper inclination angle.

[0062] As an embodiment of the present invention, determining the angle between the damper and the airflow direction according to the airflow direction inclination angle and the damper inclination angle includes: determining the difference between the airflow direction inclination angle and the damper inclination angle according to the airflow direction inclination angle and the damper inclination angle, and taking the absolute value of the difference as the angle between the damper and the airflow direction.

[0063] The absolute value of the difference between the airflow direction inclination angle and the damper inclination angle is calculated, and the absolute value is taken as the angle between the damper and the airflow direction, that is, the damper opening in the thermal power plant.

[0064] In a specific embodiment of the present invention, Figure 4 As shown in the figure, the larger the angle between the damper and the airflow direction, the smaller the airflow area and the smaller the flow rate. Usually, an angle of 0° is fully open and an angle of 90° is fully closed. Figure 4 The method for determining the angle of the damper blade 2 is specifically as follows:

[0065] 1) Calibrate the electronic inclinometer;

[0066] 2) Use an electronic inclinometer to measure the inclination angles α of the upper and lower surfaces of the airflow channel 1 respectively 1 and α 2 (When the airflow channel is a cylinder or a cuboid, α1 = α 2 ).

[0067] 3) Calculate α 3 =(α 1 +α 2 ) / 2 as the inclination angle of the airflow direction.

[0068] 4) Use an electronic inclination measuring instrument to measure the inclination angle β of the front and back sides of the damper 1 and β 2 .

[0069] 5) Calculate β 3 =(β 1 +β 2 ) / 2 as the inclination angle of the damper.

[0070] 6) Calculate |α 3 -β 3|It is the angle between the damper and the direction of air flow.

[0071] In this embodiment, specifically, for example, a damper arranged horizontally on a primary air duct, the blade angle determination process is as follows:

[0072] 1) Calibrate the electronic inclinometer;

[0073] 2) Use an electronic inclinometer to measure the inclination angles of the upper and lower surfaces of the airflow channel at 30° and 30° respectively;

[0074] 3) Angle of inclination of airflow direction α 3 =(α 1 +α 2 ) / 2=30°.

[0075] 4) Use an electronic inclinometer to measure the inclination angles of 45° and 47° on the front and back sides of the damper respectively.

[0076] 5) The inclination angle of the damper β 3 =(β 1 +β 2 ) / 2=46°.

[0077] 6) Obtain the distance between the damper and the airflow direction |α 3 -β 3 |=16°.

[0078] The present invention solves the problem that there is no quantitative measurement method for the actual angle of the blade during the damper opening calibration process, ensures that the angle displayed in the unit operation screen is consistent with the actual angle of the blade, and avoids the problems of primary and secondary air volume deviation, flame center deviation and other problems that reduce the operating efficiency and stability of the unit to the greatest extent, so that the operating personnel can better understand and control the operation of the unit, save labor costs and improve economic efficiency.
