Description

Technical Field

[0001] The invention relates to the technical field of dust filtering equipment, in particular to a dust filtering system and process for yellow phosphorus furnace gas. Background Art

[0002] Yellow phosphorus is a translucent solid with a white or light yellow exterior. It reacts easily when in contact with air. It is also called white phosphorus and is an important basic industrial raw material. The smelting process of yellow phosphorus using boilers will produce a large amount of yellow phosphorus furnace gas. The yellow phosphorus furnace gas discharged from the boiler needs to be discharged with a dust removal device for dust removal and purification before it can be discharged.

[0003] In the prior art, a Chinese patent with application number: 202222599143.1 discloses a yellow phosphorus furnace gas filtering dry dust removal device, including a cylindrical processing box, and the four corners of the bottom of the cylindrical processing box are respectively fixed with fixed legs. The yellow phosphorus furnace gas filtering dry dust removal device uses the device to perform dust removal on the furnace gas. After the left side of the connecting pipe is connected to the furnace gas outlet pipe, the furnace gas is introduced into the interior of the device through the connecting pipe. A dust filter is vertically arranged inside the fixed cylinder. The dust filter can perform primary filtration on larger dust particles and impurities in the furnace gas, and then filter again before being introduced into the interior of the device. It is a multi-stage filtration. At the same time, the used dust filter can be pulled out from the inside of the slot upwards for cleaning or replacement using the plugs fixed at both ends.

[0004] In this patent, it is inconvenient to replace the dust filter. After long-term use, the dust removal effect of the dust filter will be reduced, so the dust filter needs to be replaced. The yellow phosphorus furnace gas has a high temperature. During the filtering process of the yellow phosphorus furnace gas, the dust filter will be heated up. Therefore, if the dust filter needs to be replaced in this patent, it is necessary to wait for the temperature to drop before the dust filter can be replaced manually, which leads to disadvantages in replacement.

[0068] In this embodiment, the process of the dust filtration system for yellow phosphorus furnace gas specifically includes the following steps:

[0069] The yellow phosphorus furnace gas is transported to the air inlet pipe 1002 and filtered through the silicon carbide filter 1007, so that the dust in the yellow phosphorus furnace gas can be filtered out by the silicon carbide filter 1007. The silicon carbide filter 1007 has high temperature resistance, so that the yellow phosphorus furnace gas can be fully filtered, and the filtered yellow phosphorus furnace gas is discharged through the air outlet pipe 1003;

[0070] After long-term use, if the silicon carbide filter 1007 needs to be replaced, it is only necessary to start the motor 500 to drive the first threaded rod 5001 to rotate, the first threaded rod 5001 drives the first nut block 5002 to move, the first nut block 5002 drives the shaft rod 4007 to slide, and the shaft rod 4007 drives the first connecting rod 400 and the second connecting rod 4001 to work, so that the first connecting rod 400 and the second connecting rod 4001 can push the baffle 1008 to move upward until the baffle 1008 no longer blocks the sliding port 1004;

[0071] At the same time, during the upward movement of the first connecting rod 400 and the second connecting rod 4001, the first connecting rod 400 will drive the rotating sleeve 7002 to move, and the rotating sleeve 7002 will slide along the direction of the second guide rail 4005. During the movement of the rotating sleeve 7002, when the baffle 1008 moves upward and no longer blocks the sliding opening 1004, the resistance rod 7003 will resist the inclined plate 7001, so that the resistance column 7004 is forced to slide in the direction of the rotating sleeve 7002, so that the resistance rod 7003 can resist the pressure sensor 7007, and the pressure sensor 7007 transmits the pressure signal to the control module 900.

[0072] After the control module 900 receives the pressure signal from the pressure sensor 7007, the control module 900 energizes the first electromagnet 5004 and the second electromagnet 6001, and the first electromagnet 5004 and the second electromagnet 6001 are arranged to attract each other with opposite poles, so that the first electromagnet 5004 and the second electromagnet 6001 generate an adsorption force, and attract and fix each other. After receiving the adsorption force, the sliding sleeve 5003 slides outside the first threaded rod 5001, so that the first electromagnet 5004 and the second electromagnet 6001 are adsorbed and fixed to each other;

[0073] At this time, as the first threaded rod 5001 continues to rotate, the first electromagnet 5004 and the second electromagnet 6001 are fixed to each other by adsorption, and when the first threaded rod 5001 rotates, the second threaded rod 600 will also be driven to rotate at the same time, and when the second threaded rod 600 rotates, it will drive the second nut block 6002 to move, and the second nut block 6002 drives the sliding seat 6003 to slide, and the sliding seat 6003 drives the push plate 6006 to slide, and the push plate 6006 drives the push rod 6007 to slide, and the push plate 6006 and the push rod 6007 respectively push the unused silicon carbide filter 1007 on the second support plate 300 into the sliding opening 1004, so as to enter the processing box 100, and the used silicon carbide filter 1007 located in the processing box 100 can be pushed out, and finally supported and placed by the first support plate 200;

[0074] After the replacement is completed, the control module 900 controls the motor 500 to reverse, and the first connecting rod 400 and the second connecting rod 4001 drive the baffle 1008 to move downward until the baffle 1008 blocks the sliding opening 1004. Figure 2 In the situation shown in the figure, at the same time, the second threaded rod 600 rotates synchronously with the first threaded rod 5001, and the second nut block 6002 drives the push plate 6006 and the push rod 6007 to slide back and reset to the initial position;

[0075] At this time, the resistance rod 7003 returns and no longer resists the inclined plate 7001, so that the resistance column 7004 pushes the resistance rod 7003 to slide outward under the elastic force of the second spring 7005 and no longer resists the pressure sensor 7007. At this time, after the control module 900 cannot receive the pressure signal, the control module 900 turns off the first electromagnet 5004 and the second electromagnet 6001, so that under the elastic force of the first spring 50010, the slide plate 5007 pushes the sliding sleeve 5003 back through the push ring 5006, so that there is a certain gap between the first electromagnet 5004 and the second electromagnet 6001.

[0076] Therefore, in this embodiment, the silicon carbide filter 1007 can be replaced quickly and conveniently without manual operation, thus avoiding harm to workers caused by high temperature.

[0077] Embodiment 2:

[0078] The difference between this embodiment and the first embodiment is that in order to regularly detect whether the yellow phosphorus furnace gas still contains dust after filtering or whether the dust content meets the standard, this embodiment is set up, and the specific technical scheme is as follows:

[0079] Among them, a sampling tube 800 is provided outside the air outlet pipe 1003, a valve 8001 is fixedly connected between the sampling tube 800 and the air outlet pipe 1003, a filter box 8002 is fixedly connected in the sampling tube 800, a lifting tube is provided through the filter box 8002, a filter membrane 8004 is fixedly connected in the lifting frame 8003, a fixing frame 8005 is fixedly connected to the top of the lifting frame 8003, and the fixing frame 8005 is detachably fixedly connected to the filter box 8002;

[0080] Specifically, it also includes: Laser scattering sensor: The laser scattering sensor is installed in the filter box 8002, and the high-precision laser scattering particle counter can detect dust particles with a particle size range of 0.1-10μm, with a measurement accuracy of ±5%, and can output the number concentration and mass concentration data of dust particles in real time, and has data storage and transmission functions.

[0081] Filter membrane 8004 is a composite of ceramic fiber and nano-scale microporous membrane. It has a retention efficiency of over 99.9% for dust particles of 0.1-10μm. The initial mass is precisely known (accurate to ±0.05mg) and is used to collect the remaining dust after laser scattering detection for mass comparison measurement.

[0082] A flow stabilizer is also installed in the sampling tube 800: the intelligent regulating device inside the flow stabilizer can stabilize the furnace gas sampling flow rate within the set value ±0.03L / min range, ensuring the stability of the flow rate during the detection process and reducing the detection error caused by flow fluctuations;

[0083] It also includes temperature and pressure compensation sensors: a high-precision temperature sensor (accuracy ±0.1°C) and a separate pressure sensor (accuracy ±0.2kPa), which monitor the temperature and pressure of the furnace gas at the sampling point in real time and transmit the data to the data processing unit for automatic compensation and correction of the detection data.

[0084] Data acquisition and processing system: It consists of a high-performance computer and a professional data acquisition card. It can simultaneously receive data from laser scattering sensors, temperature and pressure compensation sensors, and perform real-time processing and analysis based on preset algorithms, ultimately outputting accurate dust detection results.

[0085] The specific method is as follows:

[0086] The filter membrane was dried in a vacuum oven at 120 °C for 3 hours, then cooled to room temperature in a desiccator, and its mass was accurately weighed using a high-precision analytical balance (accuracy ± 0.05 mg), recorded as m 1 (mg), laser scattering sensor, precision filter, flow stabilizer, temperature and pressure compensation sensor and other components are tightly connected without leakage.

[0087] Subsequently, according to the furnace gas characteristics and detection requirements, the sampling flow rate Q (L / min) and sampling time t (min) are set in the data acquisition and processing system.

[0088] Next, the flow stabilizer is turned on, and the furnace gas enters the laser scattering sensor, which monitors the number concentration C of dust particles in the furnace gas in real time. n (pcs / L) and mass concentration C′ m (mg / L), the data acquisition and processing system records data every 10 seconds; the furnace gas flowing out of the laser scattering sensor enters the filter membrane, and the dust particles are further intercepted and collected.

[0089] During the sampling process, the flow display of the flow stabilizer is continuously observed to ensure that the sampling flow is stable at the set value Q. At the same time, the temperature and pressure compensation sensor monitors the temperature T (℃) and pressure P (kPa) of the furnace gas in real time, and the data is also collected and recorded synchronously.

[0090] After sampling, turn off the flow stabilizer and take out the precision filter. Put it in the vacuum drying oven again and dry it at 120℃ for 3 hours, then cool it to room temperature in the dryer. Use a high-precision analytical balance to accurately weigh the mass of the precision filter after drying and cooling, and record it as m 2 (mg).

[0091] Finally, the average mass concentration C during the laser scattering sensor detection period is calculated m ;

[0092] The calculation formula is as follows:

[0093]

[0094] Where N is the number of data records within the sampling time. This formula represents the average value C m The calculation method is the value obtained by each sampling in N sampling times The sum of divided by the number of samples N.

[0095] Next, calculate the sampling volume V:

[0096] First, the average temperature during the sampling process Convert to Kelvin temperature T avgK =T avg +273.15(K).

[0097] (where T 0 =273.15K, P 0 =101325Pa)

[0098] Calculate the average pressure And converted to Pascal pressure P avgPa =p avg ×1000(Pa);

[0099] According to the ideal gas state equation, the sampling volume V raw =Q×t(L);

[0100] The corrected sampling volume calculation formula is: (where T 0 =273.15K, P 0 =101325Pa);

[0101] Finally, the dust concentration C″ is calculated based on the mass measurement m :

[0102]

[0103] Comprehensive calculation of final dust concentration C final ; The calculation formula is as follows:

[0104] C final =α×C m +(1-α)×C m ″ (wherein, α is a laser scattering detection weight coefficient determined experimentally, and has a value range of 0.4-0.6, for example, 0.5).
