Description

Technical Field

[0001] This invention relates to the field of environmental protection equipment technology for thermal power generation, specifically to a dust treatment device and control method for thermal power generation. Background Technology

[0002] During the thermal power generation process, coal-fired boilers produce a large amount of dust-laden flue gas. If pollutants such as sulfide particles contained in the flue gas are directly emitted, they will not only seriously pollute the atmospheric environment, but may also cause irreversible damage to the human respiratory system. At the same time, they do not meet the increasingly stringent environmental emission standards. Therefore, dust treatment of flue gas generated by thermal power generation is a crucial step.

[0003] Existing dust treatment devices have several drawbacks in practical use. On the one hand, they are not effective at treating fine dust, which is difficult to effectively accumulate and separate, resulting in the final exhaust gas still containing a high concentration of fine particulate matter, failing to meet stringent environmental protection requirements. On the other hand, in the dust treatment process, traditional equipment relies solely on ultrasonic vibration for dust removal, making it difficult to effectively remove thick, wet dust accumulated on the filter structure, thus affecting the filtration effect and the normal operation of the device.

The top and bottom inner walls of the condensation tube 3 are provided with clips 302 for fixing the curved magnetic plates 301. The condensation cavities 303 formed by the curved magnetic plates 301 can use magnetic force to attract charged fine dust particles, promote their condensation into larger particles, improve the aggregation effect of fine dust, and facilitate subsequent separation processing.

[0036] like Figure 4 As shown, a climbing slope 10 is provided inside the dust inclined climbing pipe 4, and a filter inlet 13 is provided on one side of the dust inclined climbing pipe 4. A filter assembly 6 for filtering dust is provided inside the filter inlet 13, and the filter assembly 6 is horizontally mounted in the middle section of the climbing slope 10.

[0037] The filter assembly includes a filter frame, a blocking strip, a filter screen, a handle, a vibrator fixing frame, and a wiring groove. The filter frame has a filter screen inside. A blocking strip is provided on the side of the filter frame near the filter inlet, and a handle is provided on the side of the blocking strip away from the aluminum frame. A vibrator fixing frame is provided at the center of the rear end of the filter screen.

[0039] The ultrasonic dust removal assembly includes an ultrasonic transducer, a second power supply tube, a control console, and a touch screen. The ultrasonic transducer is located inside the transducer fixing frame. The second power supply tube is located inside the wiring groove. One end of the second power supply tube is connected to the ultrasonic transducer.

[0040] like Figure 5 As shown, the ultrasonic dust removal assembly 7 includes an ultrasonic transducer 701, which is located inside the transducer fixing frame 605.

The vibration generated by the ultrasonic transducer 701 can shake off excess dust attached to the filter screen 603, which is especially suitable for removing thin dust layers after being treated by the mechanical dust removal assembly 8. It works with the filter assembly 6 to maintain the filtration effect and avoid dust blockage affecting the operation of the device.

[0041] The mechanical dust removal assembly includes a scraper that fits against the front end of the filter screen. Two sets of push rods are symmetrically arranged at the upper end of the scraper. The ends of the two sets of push rods away from the scraper extend to the outer end of the surface of the inclined dust riser. A mounting frame is provided at the outer end of the surface of the inclined dust riser. Mounting plates are provided on both the front and rear sides of the bottom of the mounting frame. Two sets of motors corresponding to the push rods are symmetrically arranged at the upper end of the mounting frame. The ends of the two sets of push rods away from the scraper pass through the inclined dust riser and the mounting frame and are connected to the motors.

[0042] like Figure 6 As shown, the mechanical dust removal assembly 8 includes a scraper 805, which is attached to the front end of the filter screen 603. Two sets of push rods 803 are symmetrically arranged at the upper end of the scraper 805. The ends of the two sets of push rods 803 away from the scraper 805 extend to the outer end of the surface of the dust inclined climbing pipe 4. A mounting bracket 801 is provided at the outer end of the surface of the dust inclined climbing pipe 4. Mounting plates 802 are provided on both the front and rear sides of the bottom of the mounting bracket 801.

The ends of the two sets of push rods 803 away from the scraper 805 pass through the dust inclined climbing pipe 4 and the mounting bracket 801 and are connected to the motors 804. By attaching the scraper 805 to the filter screen 603, excessive dust can be scraped off under the drive of the motors 804, ensuring that the filter screen 603 continuously and efficiently filters.

[0043] like Figure 4 As shown, the dust inclined climbing pipe also includes a collection port 11 and a collection installation frame 12; the bottom of the climbing slope is provided with a collection port 11, and the lower end of the collection port 11 is provided with a collection installation frame 12.

[0044] The working principle of this embodiment is as follows: the power supply 204 supplies power to the electrode plate 201 of the auxiliary electrical component 2; the power module 205 transmits power to the electrode plate 201 through the first power tube 207 and the connector 206, causing the discharge needle 202 on the electrode plate 201 to start working; simultaneously, the control console 703 is opened, and the ultrasonic transducer 701 is activated through the touch screen 704, putting it into standby mode; when the dust-laden flue gas generated by the thermal power plant enters the auxiliary electrical tube 1, under the action of the auxiliary electrical component 2, the dust in the flue gas is... The dust particles are charged, and then the flue gas enters the condensation tube 3. In the condensation cavity 303 formed by the curved magnetic plate 301, the charged tiny dust particles are condensed into larger particles under the action of magnetic force. Subsequently, the flue gas enters the dust inclined climbing tube 4 and flows upward along the climbing slope 10. Under the action of gravity and airflow, some of the larger dust particles will settle to the bottom of the climbing slope 10 and enter the dust container through the collection port 11. When the flue gas passes through the filter assembly 6, the filter screen 603 will filter the remaining dust.

[0045] During the filtration process, if a thick layer of dust accumulates on the filter screen 603, the motor 804 of the mechanical dust removal component 8 is activated. The motor 804 drives the push rod 803 to move the scraper 805 up and down on the front surface of the filter screen 603, scraping off the excessively thick dust. The scraped-off dust will also fall into the collection port 11. For the thinner dust layer remaining after the scraper 805 is processed, the ultrasonic transducer 701 is activated through the control panel 703. The vibration generated by the ultrasonic transducer 701 shakes it off, thus maintaining the filtration effect of the filter screen 603. The filtered clean flue gas is discharged through the flue pipe 9. After use, turn off the power and the control panel 703, and remove the filter frame 601 from the filter insertion port 13 through the handle 604. Thoroughly clean or replace the filter screen 603 and clean the dust in the dust container.

[0046] Example 2 The difference between this embodiment and Embodiment 1 is that: 1) This embodiment also includes a dust concentration sensor, which is installed at the inlet and outlet of the processing device.

[0047] 2) This embodiment also includes a weighing sensor, which is mounted on the filter assembly 6.

[0048] This control method monitors data in real time using dust concentration sensors and weighing sensors, and dynamically adjusts the discharge voltage of the electrified component 2, the magnetic field strength of the condensation tube 3, the power of the ultrasonic dust removal component 7, and the frequency of the mechanical dust removal component 8 to achieve multi-parameter synergistic optimization and improve the overall purification efficiency of the device.

[0049] This embodiment also provides a control method for a dust treatment device for thermal power generation, including the following steps: Dust concentration sensors are installed at the inlet and outlet of the processing device, and weighing sensors are installed on the filter assembly 6. Based on the difference between the measured values ​​of the outlet dust concentration sensor and the measured values ​​of the inlet and outlet dust concentration sensors, adjust the discharge voltage of the attached component 2 and the magnetic field strength of the condensation tube 3. Adjust the working power of the ultrasonic dust removal component 7 or the working frequency of the mechanical dust removal component 8 based on the measured value of the weighing sensor.

[0050] Specifically, the dust concentration C0 at the inlet of the electrified pipe 1, the condensed dust concentration C1 at the outlet of the condensation pipe 3, and the pressure difference ΔW before and after the filter assembly 6 are monitored by the dust concentration sensor 9; at the same time, the wind speed V in the electrified pipe 1 is monitored by the wind speed sensor. Dynamic wind speed adjustment: Based on the original dust concentration C0 and the preset benchmark value C base The comparison results show that the wind speed V inside the duct 1 is adjusted by the variable frequency fan: When C0 > 1.2C base At that time, increase the wind speed to V. max 80%-90%, enhancing the transport efficiency of large-particle ferromagnetic materials; When C0 ≤ 0.8C base At that time, reduce the wind speed to V. min 60%-70%, extending the residence time of fine dust in the charged component 2 and the condensation tube 3; Graded control of electrical intensity: Based on the coupling relationship between wind speed V and dust concentration C0, the discharge voltage U of electrode 201 is adjusted via power module 205: When V ≥ 15 m / s and C0 > 1.5C base At that time, U will be promoted to U. max 80%-90%, enhancing the charge-attachment efficiency of large-particle ferromagnetic materials; When V < 10 m / s and C0 ≤ C base When, reduce U to U min 60%-70% to avoid excessive charging of fine dust, which could cause adhesion to the inner wall of the condensation tube 3; Synergistic optimization of magnetic field and ultrasound: Based on the dust concentration C1 after condensation, the magnetic field strength B of the condensation tube 3 and the vibration frequency f of the ultrasonic transducer 701 are dynamically adjusted via the control console 703. When C1>50mg / m 3 At the same time, B is increased to 0.3-0.5T and f to 28-35kHz to enhance the coagulation and ultrasonic stripping effect of tiny ferromagnetic dust. When C1≤20mg / m 3 At the same time, reduce B to 0.1-0.2T and f to 15-20kHz to reduce energy consumption and reduce the risk of vibration damage to the filter plate (603); Mechanical dust removal with adaptive cleaning: Based on the weight difference ΔW of the filter components 6, the reciprocating frequency F of the scraper 805 is controlled by the motor 804. When ΔW≥800g, increase F to 3-5 times / minute to quickly remove the dust accumulated on the surface of the filter screen (603); When ΔW≤300g, reduce F to 0.5-1 times / minute to reduce mechanical wear and extend the service life of filter screen 603; Multi-parameter closed-loop feedback: The real-time data from the aforementioned dynamic wind speed adjustment, graded control of electrical intensity, and synergistic optimization of magnetic field and ultrasound is transmitted to the central controller. The adjustment thresholds of each parameter are dynamically corrected through a PID algorithm, forming a synergistic control closed loop of wind speed-electricity-magnetic field / ultrasound-mechanical dust removal.

[0051] The beneficial effects of this invention are summarized as follows: This application employs a three-stage treatment structure consisting of an electrified component 2, a condensation tube 3, and a filter component 6. First, the electrified component 2 charges the dust particles in the flue gas. Then, the condensation chamber 303 formed by the curved magnetic plate 301 of the condensation tube 3 promotes the agglomeration of fine dust particles into larger particles. Finally, the filter component 6 within the dust-prone ascending pipe 4 separates the flue gas from the dust, significantly improving the treatment effect on fine dust and drastically reducing the concentration of fine particulate matter in the final emitted flue gas, meeting increasingly stringent environmental protection requirements. The mechanical dust removal component 8 quickly scrapes away excessively thick dust, ensuring the air permeability of the filter screen 603. The ultrasonic dust removal component 7 effectively shakes off thinner dust layers, preventing dust from clogging the filter screen 603.
