Description

Technical Field

[0002] With the widespread use of coal resources, the treatment of high-chlorine coal has become an important research topic in the coal processing field. During combustion or other processing, the chlorine contained in high-chlorine coal may be converted into harmful substances such as hydrogen chloride, leading to a series of problems such as equipment corrosion, environmental pollution, and adverse effects on subsequent processes. Therefore, the separation, detection, and precise control of chlorine in high-chlorine coal is of paramount importance in ensuring the efficiency, safety, and environmental friendliness of coal processing.

[0003] In the process of chlorine separation and detection in coal, traditional washing detection control tends to focus on whether the coal meets the standards after chlorine separation, lacking detection of the chlorine separation and detection device itself, which easily leads to waste of resources and low reliability.

[0067] The implementation of this disclosure will be described in detail below with reference to the specific accompanying drawings:

[0068] Figure 1 A schematic diagram of the control system for a chlorine element separation and detection device in coal provided in this embodiment of the present disclosure; Figure 5 This is a schematic diagram of the control system for a second type of chlorine element separation and detection device in coal provided in this disclosure embodiment. (Refer to...) Figure 1 and Figure 5 The control system for a chlorine separation and detection device in coal includes:

[0069] Flow detection module 10, flow control module 11, water pressure detection module 12, water pressure control module 13, temperature detection module 14, temperature control module 15, chloride ion detection module 16, solenoid valve 17, electric heater 18, water pump 19, central control module 20 and first alarm module 21;

[0070] The input terminal of the flow control module 11 is connected to the flow output terminal of the central control module 20, and the output terminal of the flow control module 11 is connected to the solenoid valve 17.

[0071] The input terminal of the temperature control module 15 is connected to the temperature output terminal of the central control module 20, and the output terminal of the temperature control module 15 is connected to the electric heater 18.

[0072] The input terminal of the water pressure control module 13 is connected to the water pressure output terminal of the central control module 20, and the output terminal of the water pressure control module 13 is connected to the water pump 19.

[0073] Chloride ion detection module 16 is connected to central control module 20;

[0074] The first alarm module 21 is connected to the flow detection module 10, the temperature detection module 14 and the water pressure detection module 12 respectively;

[0075] Flow detection module 10 is used to detect the water flow rate of the coal chlorine element separation detection device;

[0076] Temperature detection module 14 is used to detect the water flow temperature of the coal chlorine element separation detection device;

[0077] Water pressure detection module 12 is used to detect the water flow pressure of the chlorine separation detection device in coal;

[0078] The chloride ion detection module 16 is used to detect the chloride ion content in the water stream output by the coal chloride element separation and detection device.

[0079] In this embodiment, the water flow rate, water temperature, and water pressure are different for different types of coal. The chloride ion detection module 16 is used to detect the chloride ion content in the water output by the coal chloride element separation and detection device; the coal chloride element separation and detection device is essentially a high-chlorine coal washing and detection device.

[0080] The chloride ion detection module 16 can be a chloride ion sensor, the temperature detection module 14 can be a temperature sensor, the water pressure detection module 12 can be a pressure sensor, and the flow detection module 10 can be a flow sensor.

[0081] In this embodiment, the water flow rate can be controlled by the flow control module 11 controlling the opening of the solenoid valve 17. When the flushing flow rate needs to be adjusted, the flow control module 11 will output a corresponding signal according to the instructions of the central control module 20, causing the opening of the solenoid valve 17 to change. The water pump 19 is configured to provide pressure to the water flow, and the water pressure control module 13 controls the working state of the water pump 19 according to the instructions of the central control module 20. During the flushing process, different flushing stages have different requirements for water pressure. The electric heater 18 is configured to provide temperature to the water flow, and the temperature control module 15 receives the instructions from the central control module 20 and controls the operation of the electric heater 18 according to the preset value.

[0082] The water flow rate, water temperature, and water pressure are different at different rinsing stages. The preset flow rate, water temperature, and water pressure values ​​can be determined experimentally.

[0083] For the initial flushing stage, a large flow rate is required to quickly remove loose impurities from the surface of high-chlorine coal, such as dust, soil, and some easily washed-away chlorine compounds. Temperature requirements are relatively less stringent; room temperature can be used. This is because the removal of impurities primarily relies on the mechanical scouring action of the water flow, and temperature has a relatively small impact on this physical scouring process. Higher pressure is needed to generate sufficient impact force to break through the impurity layer on the surface of the coal particles.

[0084] For the fine rinsing stage, the flow rate will be appropriately reduced because the focus at this stage is on rinsing away the firmly adsorbed chloride ions in the coal's internal pores and on its surface. A lower flow rate allows the water to act more precisely on the coal's pores and surface. The temperature can be appropriately increased to help accelerate the dissolution of chloride ions and other harmful substances. The pressure needs to be reduced to an appropriate range. If the pressure is too high, it will cause coal particles to break, affecting the coal's structure and the accuracy of subsequent testing; if the pressure is too low, it will not ensure that the water flow can effectively penetrate into the coal's pores to flush out the adsorbed chloride ions.

[0085] For the final rinsing stage, the water flow rate can be maintained at a relatively low but stable level. The main purpose is to ensure that all washed-off impurities are thoroughly removed and prevent them from re-adsorbing onto the coal. The temperature can be appropriately reduced, returning to a level close to or slightly higher than the initial rinsing stage. This ensures rinsing effectiveness while reducing energy consumption. The water pressure can be appropriately reduced to remove residual impurities without causing additional interference to the already rinsed coal. Stable pressure also ensures consistent rinsing results.

[0086] The reaction stage can be determined by the chloride ion concentration detected by the chloride ion detection module 16. In the initial rinsing stage, a large amount of chloride ions on the surface of high-chlorine coal, as well as some easily washed-away chlorine-containing impurities, enter the rinsing water. At this time, the chloride ion concentration in the water sample after rinsing is usually high. After most of the surface impurities are washed away, the fine rinsing stage begins. At this time, chloride ions are mainly washed out from the pores inside the coal and from locations where they are firmly adsorbed on the surface. This process is relatively slow because it involves processes such as ion desorption and diffusion. Therefore, the chloride ion concentration in the water sample after rinsing is lower than the chloride ion concentration in the initial stage, but the duration is longer. In the final rinsing stage, the fluctuation of chloride ion concentration is very small, basically remaining at a low level, indicating that chloride ions in the coal have been effectively removed, and the rinsing process can be completed.

[0087] The above explanation is for understanding the logic of this application. The various water flow rates, water pressures, and water temperatures mentioned above are preset values. More precisely, the preset values ​​are the opening degree of the solenoid valve 17 corresponding to the water flow rate, the power of the water pump 19 corresponding to the water pressure, and the power of the electric heater 18 corresponding to the water temperature.

[0088] In one embodiment of this disclosure, the first alarm module 21 includes: a first flow comparator 211, a first water pressure comparator 212, a first temperature comparator 213, and an alarm unit 214;

[0089] The inverting input of the first flow comparator 211 is connected to the output of the flow detection module 10, and the non-inverting input of the first flow comparator 211 is used to receive the first flow reference value Vref4.

[0090] The inverting input of the first water pressure comparator 212 is connected to the output of the water pressure detection module 12, and the non-inverting input of the first water pressure comparator 212 is used to receive the first water pressure reference value Vref5.

[0091] The inverting input of the first temperature comparator 213 is connected to the output of the temperature detection module 14, and the non-inverting input of the first temperature comparator 213 is used to receive the first temperature reference value Vref6.

[0092] The alarm unit 214 is connected to the output terminal of the first flow comparator 211, the output terminal of the first water pressure comparator 212, and the output terminal of the first temperature comparator 213, respectively.

[0093] For example, when the chloride ion detection module 16 detects the chloride ion content in the water output from the coal chlorine element separation detection device, it is in the initial flushing stage. At this time, it sends "111" to the central control module 20. After receiving "111", the central control module 20 controls the flow control module 11 to control the solenoid valve 17 with a preset valve opening, controls the temperature control module 15 to control the electric heater 18 with a preset electric heater power, and controls the water pressure control module 13 to control the water pump 19 with a preset water pump power.

[0094] The flow detection module 10 can detect the water flow rate of the chlorine element separation detection device in coal, the temperature detection module 14 can detect the water temperature of the chlorine element separation detection device in coal, and the water pressure detection module 12 can detect the water pressure of the chlorine element separation detection device in coal.

[0095] When the flow rate value received by the first alarm module 21 is less than the preset first flow rate reference value Vref4, the first flow rate comparator 211 sends "1" to the alarm unit 214, and the alarm unit 214 is configured to receive "1" and trigger an alarm.

[0096] As can be seen from the above, this disclosure, through the flow control module 11, water pressure control module 13, and temperature control module 15, can precisely control and adjust the solenoid valve 17, water pump 19, and electric heater 18 according to the instructions of the central control module 20. This ensures that the rinsing process proceeds according to predetermined parameters, improving the rinsing effect. The chloride ion detection module 16 can detect the chloride ion content in the rinsing water and output different signals based on the chloride ion content, thereby enabling the central control module 20 to control the flow control module 11, water pressure control module 13, and temperature control module 15. When the values ​​detected by the flow detection module 10, water pressure detection module 12, and temperature detection module 14 are lower than the preset reference values, an alarm is triggered, improving the reliability of the coal chloride element separation and detection device.

[0097] Figure 2 This is a schematic diagram of the structure of a flow control module provided in an embodiment of this disclosure, with reference to... Figure 2 In one embodiment of this disclosure, the flow control module includes: a solenoid valve drive chip U1, capacitors C1 and C2, resistors R1 and R2, diode D1, and diode D2;

[0098] The first terminal of capacitor C1 is used for grounding, and the second terminal of capacitor C1 is connected to the ground terminal of solenoid valve drive chip U1;

[0099] The first end of capacitor C2 is connected to the power supply terminal of solenoid valve drive chip U1, and the second end of capacitor C2 is used for grounding.

[0100] The first end of resistor R1 is connected to the first pulse width modulation input terminal of solenoid valve driver chip U1, and the second end of resistor R1 is connected to the cathode of diode D2 and the control signal input pin of solenoid valve driver chip U1 respectively.

[0101] The anode of diode D2 is connected to the second pulse width modulation input terminal of the solenoid valve drive chip U1;

[0102] The anode of diode D1 is connected to the first terminal of resistor R2 and the first signal output terminal of solenoid valve drive chip U1, respectively; the cathode of diode D1 is connected to the second terminal of resistor R4 and the first control terminal of solenoid valve 17, respectively.

[0103] The second signal output terminal of the solenoid valve driver chip U1 is connected to the second control terminal of the solenoid valve 17.

[0104] Both the first pulse width modulation input terminal and the second pulse width modulation input terminal of the solenoid valve driver chip U1 are connected to the central control module 20.

[0105] In this embodiment, the solenoid valve driver chip U1 can be a DRV8837. The central control module 20 has a built-in signal generator, which can output different control signals through different pulse widths, thereby making the opening degree of the solenoid valve 17 different, thus controlling the flow. When the solenoid valve 17 needs to be controlled to open, the pulse width of the first input terminal of the solenoid valve driver chip U1 can be used as a reference for the opening degree control of the solenoid valve 17. When the second input terminal of the solenoid valve driver chip U2 is input, the opening degree of the solenoid valve 17 remains unchanged and is maintained.

[0106] As can be seen from the above, this disclosure controls the opening degree of the solenoid valve 17 by outputting different pulse width signals through the central control module 20. The change in the opening degree of the solenoid valve 17 directly affects the flow rate of the fluid, thus enabling flow rate regulation and meeting the needs of various application scenarios.

[0114] The cathode of diode D4 is connected to the second end of water pump interface J1, and water pump interface J1 is connected to water pump 19.

[0115] In this embodiment, the water pump driver chip U2 can control the output according to the signal sent by the central control module 20. When the control signal is transmitted, the transistor Q1 is turned on, and the signal can be transmitted to the water pump 19 through the water pump interface J1, so that the water pump 19 starts to work. The working power of the water pump 19 can vary depending on the signal input to the water pump driver chip U2.

[0116] As can be seen from the above, the water pump driver chip U2, as the core component, can perform precise output control based on the signals sent by the central control module 20, ensuring that the water pump 19 can respond quickly when it receives the correct instructions and operate according to the preset parameters. This embodiment, by adjusting the signals input to the water pump driver chip U2, can achieve precise adjustment of the working power of the water pump 19, enabling the water pressure control module 13 to adapt to different working scenarios and requirements, thereby improving the flexibility and adaptability of this disclosure.

[0139] The delay module 24 is connected to the chloride ion detection module 16 and the control module 25 respectively;

[0140] Control module 25 is connected to chloride ion detection module 16;

[0141] The control module 25 is connected to the control terminal of the first switch 22, the output terminal of the flow detection module 10, the output terminal of the temperature detection module 14, and the output terminal of the water pressure detection module 12, respectively.

[0142] In one embodiment of this disclosure, a control system for a chlorine element separation and detection device in coal includes a delay module 24, comprising: a storage unit 241, a comparison unit 242, and a delay unit 243.

[0143] Storage unit 241 is connected to chloride ion detection module 16 and comparison unit 242 respectively;

[0144] The comparison unit 242 is connected to the chloride ion detection module 16 and the delay unit 243 respectively.

[0145] In one embodiment of this disclosure, the control module 25 includes: a control unit 251, a flow storage unit 252, a temperature storage unit 253, a water pressure storage unit 254, a flow window comparison unit 255, a temperature window comparison unit 256, and a water pressure window comparison unit 257.

[0146] The flow storage unit 252 is connected to the threshold input terminal of the flow window comparison unit 255 and the control unit 251, respectively;

[0147] Temperature storage unit 253 is connected to the threshold input terminal of temperature window comparison unit 256 and control unit 251 respectively;

[0148] The water pressure storage unit 254 is connected to the threshold input terminal of the water pressure window comparison unit 257 and the control unit 251, respectively;

[0149] Control unit 251 is connected to chloride ion detection module 16;

[0150] The signal input terminal of the flow window comparison unit 255 is connected to the output terminal of the flow detection module 10;

[0151] The signal input terminal of the temperature window comparison unit 256 is connected to the output terminal of the temperature detection module 14;

[0152] The signal input terminal of the water pressure window comparison unit 257 is connected to the output terminal of the water pressure detection module 12.

[0153] In one embodiment of this disclosure, a control system for a chlorine element separation and detection device in coal further includes: a second alarm module 28;

[0154] The second alarm module 28 is connected to the control module 25;

[0155] The second alarm module 28 is configured to trigger an alarm.

[0156] In this embodiment, the chloride ion detection module 16 contains three chloride ion comparators, each of which has its corresponding reference chloride ion concentration value. The comparators can output in stages according to the chloride ion concentration, wherein the first reference chloride ion concentration value Vref1 is higher than the second reference chloride ion concentration value Vref2, and the second reference chloride ion concentration value Vref2 is higher than the third reference chloride ion concentration value Vref3.

[0157] The outputs of the three comparators can only be “000”, “001”, “011” and “111”. When the output is “000” or “001”, it indicates that the final flushing stage is in progress. When the output is “011”, it indicates that the fine flushing stage is in progress. When the output is “111”, it indicates that the initial flushing stage is in progress.

[0158] The central control module 20 controls each control module to perform flushing according to predetermined set values ​​for flow rate, water temperature, and water pressure. The output of the chloride ion detection module 16 is stored in the storage unit 241. When the output signal of the chloride ion detection module 16 changes, and the output sent by the storage unit 241 is inconsistent with the input received by the comparison unit 242, it indicates a change in the flushing stage. In order to verify the control effect of each control module, after the delay of the delay unit 243, "1" is sent to the control module 25. The control module 25 controls the first switch 22 to close. The power supply module 23 supplies power to the flow detection module 10, the water pressure detection module 12, and the temperature detection module 14. The flow detection module 10 sends the detected water flow rate to the flow window comparison unit 255 for comparison. The chloride ion detection module 16 outputs a comparison to the control unit 251. Specifically, the outputs of the first chloride ion comparator 162, the second chloride ion comparator 163, and the third chloride ion comparator 164 are all connected to the control unit 251. The control unit 251 controls the storage unit 241 to output different thresholds based on the output of the chloride ion detection module 16. When the water flow rate value sent by the flow detection module 10 is outside this threshold range, the flow window comparison unit 255 sends a "1" to the second alarm module 28, at which point the second alarm module 28 sounds an alarm. The same applies to the temperature window comparison unit 256 and the water pressure window comparison unit 257. The second alarm module 28 is configured to sound an alarm upon receiving a "1".

[0159] The first alarm module 21 and the second alarm module 28 have different functions. The function of the first alarm module 21 is to sound an alarm when the water flow rate, water temperature and water pressure are seriously abnormal, while the function of the second alarm module 28 is to sound an alarm when one of the water flow rate, water temperature or water pressure does not meet the current stage.

[0160] As can be seen from the above, this disclosure can automatically determine the rinsing stage based on the different chloride ion concentrations and adjust the control and detection strategies accordingly. This embodiment, through the delay module 24, allows the disclosure to respond and detect changes in the rinsing stage after a certain delay, providing control time. The second alarm module 28 can issue an alarm when any parameter—flow rate, temperature, or water pressure—does not meet the requirements of the current rinsing stage, improving the safety and reliability of this disclosure and enhancing the reliability of the chlorine separation and detection device in coal.

[0161] In one embodiment of this disclosure, a control system for a chlorine element separation and detection device in coal further includes: a liquid level detection module 26 and a water replenishment module 27;

[0162] The liquid level detection module 26 is connected to the water replenishment module 27;

[0163] The liquid level detection module 26 is used to detect the liquid level height in the coal chlorine element separation detection device.

[0164] In this embodiment, the liquid level detection module 26 may include a liquid level sensor, a liquid level comparator, and a liquid level control unit. When the liquid level detected by the liquid level sensor is lower than a preset value, it indicates that the water volume of the chlorine element separation detection device in coal is too low. At this time, the output is "1", and the liquid level control unit controls the water replenishment module 27 to replenish water until the liquid level comparator sends "0".

[0165] As can be seen from the above, this embodiment, through the liquid level detection module 26, enables the present invention to monitor the liquid level in the coal chlorine element separation and detection device in real time, preventing the coal chlorine element separation and detection device from being damaged due to insufficient water, thereby improving the safety and stability of the entire present invention.

Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
