[0014] Compared with the prior art, the beneficial effects of this utility model are: the powder dust collection device for cement production not only realizes a variety of dust collection and filtration functions, but also realizes the collection and reuse function, and also realizes the emission gas detection function;
[0015] (1) By setting up a venturi tube, filter element, exhaust pipe and atomizing nozzle, when in use, the first suction pump sucks dust and exhaust gas into the venturi tube. When the gas passes through the venturi tube, it is accelerated outward by the Venturi effect. When it passes through the end of the venturi tube, the powder particles accelerate downward and fall into the collection box. The light gas is sucked into the filter tube by the second suction pump. When it passes through the filter element, the gas is further filtered and screened, and then discharged upward to the exhaust pipe. At the same time, the water pump draws water from the water tank and sprays fine mist into the exhaust pipe through the atomizing nozzle. The dust particles after combining with the water mist fall downward to the top of the receiving tray for collection. The clean gas is discharged outward from the top of the exhaust pipe after two dry dust removals and the final wet dust removal. The triple dust removal ensures that the gas discharged outward through the exhaust pipe meets the acceptance standards, realizing a variety of dust collection and filtration functions.
[0016] (2) By setting up a storage box, controller and speaker, when in use, the first air pump sucks the dust into the Venturi tube. Due to the narrow tube in the middle of the Venturi tube, the powder accelerates downward due to the Venturi effect. After reaching the tail end of the Venturi tube, the particles in the powder fall into the storage box for collection by gravity. A weight threshold can be set in the controller. After the particles in the storage box have been collected to the preset weight, a prompt will be made through the speaker. The staff can take out the storage box and collect and reuse the powder particles inside, thus realizing the collection and reuse function.
[0017] (3) By setting up warning lights, a comprehensive atmospheric sampler and a sampling head, when using it, because cement production needs to meet gas emission standards, after the first two dry dust removals and the last wet dust removal, the gas discharged from the exhaust pipe can be measured. The gas is discharged from the exhaust pipe and the gas is detected by the sampling head. The data is synchronously transmitted to the comprehensive atmospheric sampler. If there is any abnormality in the data, the warning light will flash to remind the staff to check the dust removal equipment, thus realizing the emission gas detection function.

A T-shaped bracket 13 is located at the top of the exhaust pipe 11. The bottom of the bracket 13 is fixedly connected to the receiving plate 14.

The top diameter of the T-shaped bracket 13 is larger than the top diameter of the exhaust pipe 11. It has triple dust protection and excellent effect.
[0026] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, during use, the first suction pump 2 draws dust and exhaust gas into the venturi tube 3. As the gas passes through the venturi tube 3, it is accelerated outward due to the Venturi effect. When it passes the end of the venturi tube 3, the powder particles accelerate downward and fall into the collection box 4. The lighter gas is drawn into the filter tube 6 by the second suction pump 8. When it passes through the filter element 7, the gas is further filtered and sieved, and then discharged upward to the exhaust pipe 11. At the same time, the water pump 10 draws water from the water tank 9 and sprays fine mist into the exhaust pipe 11 through the atomizing nozzle 12. The dust particles that combine with the water mist fall downward to the top of the receiving tray 14 for collection. The clean gas, after passing through two dry dust removal processes and the final wet dust removal, is discharged outward from the top of the exhaust pipe 11. The triple dust removal ensures that the gas discharged outward through the exhaust pipe 11 meets the acceptance standards, and the dust removal is highly efficient and thorough.
[0027] A weight sensor 15 is installed at the bottom of the storage box 4, a controller 16 is fixedly connected to the front end of the dust collection box 1, an alarm light 17 is fixedly connected to the front end of the controller 16, a speaker 18 is installed below the alarm light 17, the weight sensor 15 is electrically connected to the controller 16, the alarm light 17 and the speaker 18 are electrically connected to the controller 16, and the powder is collected and the particles are screened out for easy reuse.
[0028] Specifically, such as Figure 1 and Figure 2 As shown, during use, the first suction pump 2 draws the dust into the venturi tube 3. Due to the narrow tube in the middle of the venturi tube 3, the powder accelerates downward due to the Venturi effect. After reaching the tail end of the venturi tube 3, the particles in the powder fall downward with gravity into the collection box 4 for collection. A weight threshold can be set in the controller 16. After the particles in the collection box 4 have reached the preset weight, a prompt will be given through the speaker 18. The staff can then take out the collection box 4 to collect and reuse the powder particles inside. The measurement is accurate and the automatic collection is convenient for employees to operate.
[0029] A comprehensive atmospheric sampler 19 is fixedly connected to the top of the water tank 9. A sampling head 20 is fixedly connected to the right side of the comprehensive atmospheric sampler 19. The comprehensive atmospheric sampler 19 is electrically connected to the controller 16. The sampling head 20 protrudes from the right side of the water tank 9 and extends to the top of the exhaust pipe 11 for easy detection of the discharged gas.
[0030] Specifically, such as Figure 1 and Figure 2 As shown, during use, since cement production needs to meet gas emission standards, after the first two dry dust removal processes and the final wet dust removal, the gas discharged from the exhaust pipe 11 can be measured. The gas is discharged from the exhaust pipe 11 and detected by the sampling head 20. The data is synchronously transmitted to the integrated atmospheric sampler 19. If there is any abnormality in the data, the warning light 17 will flash to remind the staff to check the dust removal equipment and conduct pre-testing to facilitate subsequent work.
[0031] Working Principle: In use, this invention firstly draws dust and exhaust gas into the Venturi tube 3 via a first suction pump 2. As the gas passes through the Venturi tube 3, it is accelerated outwards due to the Venturi effect. At the end of the Venturi tube 3, powder particles accelerate downwards and fall into the collection box 4. The lighter gas is drawn into the filter tube 6 by a second suction pump 8. After passing through the filter element 7, the gas undergoes further filtration and sieving before being discharged upwards to the exhaust pipe 11. Simultaneously, a water pump 10 draws water from the water tank 9 and sprays fine mist into the exhaust pipe 11 through an atomizing nozzle 12. The dust particles, combined with the water mist, fall downwards to the top of the receiving tray 14 for collection. The clean gas, after undergoing two dry dust removal processes and a final wet dust removal, is discharged from the top of the exhaust pipe 11. This triple dust removal ensures that the gas discharged through the exhaust pipe 11 meets acceptance standards. During use, the first suction pump 2... After dust is drawn into the venturi tube 3, due to the narrow tube in the middle of the venturi tube 3, the dust accelerates downward due to the Venturi effect. After reaching the tail end of the venturi tube 3, the particles in the dust fall downward with gravity into the collection box 4 for collection. A weight threshold can be set in the controller 16. After the particles in the collection box 4 have reached the preset weight, a prompt will be made through the speaker 18. The staff can then take out the collection box 4 to collect and reuse the dust particles inside. During use, because cement production needs to meet gas emission standards, after the first two dry dust removal processes and the final wet dust removal process, the gas discharged from the exhaust pipe 11 can be measured. The gas is discharged outward from the exhaust pipe 11, and the gas is detected by the sampling head 20. The data is synchronously transmitted to the integrated atmospheric sampler 19. If there is any abnormality in the data, the warning light 17 will flash to remind the staff to check the dust removal equipment.
