The thermometer is mainly used for checking the integral heating condition of the conical section, comparing the integral heating condition with the desulfurizing agent humidity and the heating time, and obtaining a corresponding numerical relation for data analysis.
The discharging conical section of the desulfurizing tower is also provided with a hygrometer 5, the selectable setting position of the hygrometer is the discharging conical section between the upper and lower adjacent air pipes, and the humidity value of the desulfurizing agent is detected; the hygrometer 5 is connected with the background control system, and the hygrometer is mainly used for measuring the humidity of the desulfurizer in the discharging conical section and transmitting the measured humidity value of the desulfurizer to the background control system, and the background control system determines the adjustment scheme according to the received humidity value of the desulfurizer and parameters such as the temperature and the flow of steam.
The concrete form and the position of setting up of hygrometer do not do the restriction, realize monitoring the humidity of desulfurizer can, if the appearance must be in the leakproofness that the conical section trompil then need to pay attention to each position connection, prevent that the flue gas from revealing.
The background control system is preset with an optimal humidity value and a parameter range of normal work of each instrument, and mainly has the functions of regularly summarizing data returned by the instruments, analyzing according to the data, adjusting the optimal humidity, further analyzing the relation among steam consumption, temperature, desulfurizer humidity, weather and cost, adjusting to the most energy-saving, safest and most economical parameter scheme, and simultaneously monitoring the working states of the heating coil and each instrument.
The specific regulating and controlling thought is as follows: the heating temperature of the discharging conical section is regulated and controlled by controlling the steam flow, and the steam flow is assisted to be controlled by instrument feedback data (flow, force and humidity).
The humidity value of the desulfurizer agglomeration is determined through experiments, the optimal humidity value which is economic and suitable is input into a background control system, a hygrometer 5 monitors the humidity value of the desulfurizer in the discharging conical section and transmits a measured value to the background control system for comparison, the background control system controls a remote control valve 1 to act by taking the measured value as a judgment value, so that the steam flow is controlled, the temperatures of the desulfurizer in the discharging conical section and the discharging conical section are controlled, and the background control system can select full-automatic control or manual control.
Specifically, the background control system receives a monitoring value transmitted by the hygrometer 5, and when the monitoring value is in a set optimal humidity value range, the background control system judges that the heating pipeline at the discharging conical section is in a normal state, the remote control valve 1 does not act at the moment, the steam flow is constant, and the temperature of the desulfurizer in the discharging conical section is constant.
When the background control system receives a monitoring value transmitted by the hygrometer 5 and the monitoring value is lower than a set optimal humidity value range, the humidity of a desulfurizer in the discharging conical section is too low, namely the temperature in the discharging conical section is too high, cooling control is needed, and the reduction of steam consumption is taken as a main regulation measure;
the background control system judges that the heating coil at the discharging conical section is in a high-temperature state, the background control system gives a control instruction of cooling regulation, the remote control valve 1 automatically acts after receiving the command, the valve is gradually closed, the steam flow is reduced, the temperature of the desulfurizer in the discharging conical section is reduced, and the regulation is finished until the humidity value of the desulfurizer returns to the optimal numerical range.
In other embodiments, the valve can be controlled manually, that is, after the background control system gives a control instruction of "cooling control", the remote control valve 1 is controlled manually to close the valve gradually, so that the steam flow is reduced, the temperature of the desulfurizer in the discharge conical section is reduced until the humidity value of the desulfurizer returns to the optimal value range, the control is finished, that is, the control of the valve can be controlled automatically or manually, and the specific control mode can be selected automatically, so that excessive limitation is not imposed.
When the background control system receives a monitoring value transmitted by the hygrometer 5 and the monitoring value is higher than a set optimal humidity value range, the humidity of the desulfurizer in the discharging conical section is too high, namely the temperature in the discharging conical section is too low, temperature rise control is needed, and at the moment, the increase of steam consumption is taken as a main regulation and control measure to prevent the desulfurizer from being hardened due to the continuous increase of the humidity;
the background control system judges that the heating coil at the discharging conical section is in a low-temperature state, the background control system gives a control instruction of heating regulation, the remote control valve 1 automatically acts after receiving the instruction, the valve is gradually opened, the steam flow is increased, the temperature of the desulfurizer in the discharging conical section is further increased until the humidity value of the desulfurizer returns to the optimal numerical range, and the regulation is finished.
In the process of controlling the action of the remote control valve 1 through the background control system, the opening of the remote control valve 1 is monitored through the background control system, when the valve reaches the limit position of the valve, the valve stops acting, and the background control system gives an alarm.
Similarly, in other embodiments, the valve may be manually controlled, that is, after the background control system gives a control instruction of "temperature rise control", the remote control valve 1 is manually controlled to gradually open the valve, so that the steam flow is increased, and the temperature of the desulfurizing agent in the discharging conical section is increased until the humidity value of the desulfurizing agent returns to the optimal value range, and the control is finished, that is, the control of the valve may be automatically controlled or manually controlled, and the specific control mode may be automatically selected, which does not impose too much restriction.
The background control system can not only regulate and control the work of the heating coil, but also monitor the working state of the heating pipeline in the regulating and controlling process and send out abnormal warning.
For convenience of understanding, the present embodiment is described by taking four abnormal states, i.e., blockage, air leakage, high pressure abnormality, and instrument and valve abnormality, as follows:
1. blocking;
the blockage is divided into two cases, one is the blockage of the main pipe, and the other is the blockage of the heating pipeline.

The main pipe blockage is divided into two conditions of air inlet main pipe blockage and air outlet main pipe blockage, at the moment, the pressure gauge 3 is combined for further judgment, when the numerical value of the pressure gauge 3 has pressure and the pressure is basically unchanged, the air outlet main pipe blockage is formed, the background control system sends a judgment instruction of 'air outlet main pipe blockage', simultaneously closes the remote control valve 1, and sends an abnormal warning;
when the numerical value of the pressure gauge 3 has no pressure or the pressure tends to 0, the air inlet main pipe is blocked, the background control system sends a judgment instruction of 'the air inlet main pipe is blocked', and simultaneously, the remote control valve 1 is closed and an abnormal warning is sent.
And (3) blocking of the heating coil: the background control system receives the monitoring values of each monitoring instrument, when the first flowmeter 2 at the air inlet main pipe and the second flowmeter 6 at the air outlet main pipe are 0 or tend to 0, the first thermometer 4 at the air inlet main pipe and the second thermometer 7 at the air outlet main pipe are reduced, the temperature reduction speed at the air outlet main pipe is higher than that of the air inlet main pipe, the numerical value change of each monitoring instrument cannot be influenced by the action of the remote control valve 1, or the influence is small, the main pipe is judged to be blocked, at the moment, the background control system sends a judgment instruction of 'heating coil blockage', the remote control valve 1 is closed at the same time, and an abnormal warning is sent.
2. Air leakage;
in the present embodiment, the heating duct leakage is taken as an example for explanation.
Specifically, the background control system receives monitoring values of the flowmeters, the first flowmeter 2 at the air inlet main pipe is larger than the second flowmeter 6 at the air outlet main pipe, the difference value of the flow rates of the air inlet main pipe and the air outlet main pipe tends to a certain value when the remote control valve 1 acts, the value is larger than an allowable difference value, at the moment, the background control system sends a judgment instruction of heating pipeline air leakage, simultaneously closes the remote control valve 1, and sends an abnormal warning.
3. High pressure anomaly;
the high pressure is unusual mainly monitors the pressure of steam in the female pipe of admitting air, and then judges the abnormal degree of heating pipe internal pressure, and is specific, utilizes manometer 3 on the female pipe of admitting air to monitor the pressure of steam in the female pipe of admitting air to transmit monitoring value to backstage control system, when this monitoring value surpassed the high pressure safety value of preset, backstage control system judged "high pressure unusual", control remote control valve 1 and close, sent unusual warning simultaneously.
4. Instrument, valve anomaly;
the background control system automatically establishes a data model for data fed back by various instruments and valves, compares the data with historical data at regular time, judges that the instruments and the valves are abnormal if a certain data is abnormal, sends an abnormal warning to inquire whether the valves are turned off, and automatically turns off the remote control valves 1 by default if no operation is performed within a period of time.
It is understood that in other embodiments, the flow meter, the pressure gauge, the thermometer, the flow meter, and the like may be replaced by sensors, as long as monitoring and transmission of monitoring data are possible, which is not limited herein.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
