Description

Technical Field

[0001] This utility model relates to the field of electrostatic precipitator technology, specifically to a high-efficiency purification device for electrostatic precipitators at the kiln head. Background Technology

[0002] In the cement production process, in order to reduce dust pollution to the atmosphere, a high-efficiency dust collector is set up at the kiln head to efficiently capture dust particles in the exhaust gas, so that the emitted gas meets environmental protection standards, protects the ecological environment and the health of surrounding residents, and at the same time reduces production interruptions and equipment corrosion caused by dust emission problems, and extends the service life of equipment.

[0003] A Chinese patent with publication number CN215354014U discloses a high-temperature electrostatic precipitator for cement production, which solves the problem that existing electrostatic precipitators, which transport dust through sealed pipes, accumulate dust on the inner wall of the pipes over long-term use. The precipitator includes an electrostatic precipitator with a housing at its bottom and a guide trough at its bottom, which are connected. A discharge port is installed on one side of the bottom of the guide trough. A rotating rod is installed inside the cavity of the housing, with one end connected to the inner wall of the housing. A transmission component is installed at the end of the rotating rod that penetrates the housing. Connecting rods are installed at equal intervals on one side of the rotating rod, and an arc-shaped brush plate is installed on one side of the connecting rod. The arc-shaped brush plate effectively removes dust accumulated on the inner wall of the housing, and the transmission component allows for intermittent dust removal by the arc-shaped brush plate, effectively preventing dust accumulation on the inner wall of the housing.

[0004] The aforementioned patent still has the following shortcomings: it suffers from uneven distribution of exhaust gas after entering the device. Existing devices typically use airflow distribution plates to guide the exhaust gas, but due to the high dust content in the exhaust gas at the kiln head, the airflow distribution plates are prone to clogging, affecting the dispersion of airflow. This results in significant differences in dust removal efficiency in different areas of the electric field, with some areas having excessively high dust concentrations, affecting the overall dust removal efficiency. Furthermore, the uneven airflow distribution causes different amounts of dust deposition in different parts of the electrode system, accelerating the wear and corrosion of local electrodes, shortening the lifespan of the electrodes, and increasing equipment maintenance costs. Utility Model Content

[0005] This utility model provides a high-efficiency purification device for electrostatic precipitator at the cellar head, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] This utility model provides a high-efficiency purification device for electrostatic precipitators at the kiln head, including a housing, and further comprising:

[0008] The frame is fixed to the bottom of the housing, and the top of the housing is detachably fitted with a top cover;

[0009] The ash hopper is fixed to the bottom of the machine casing, and an ash discharge blade is installed inside the bottom of the ash hopper. A second drive motor with the output shaft end connected to one of the ash discharge blades is installed on one side of the ash hopper, and a transmission belt is connected to one side of the ash discharge blade.

[0010] An intake pipe is installed on one side of the housing, and an exhaust port is installed on the other side of the housing;

[0011] A ash discharge pipe is fixed at the bottom of the ash hopper, and a spiral blade shaft is rotatably connected inside the ash hopper. A first drive motor with an output shaft end connected to the spiral blade shaft is installed on one side of the ash discharge pipe.

[0012] The spray structure is located on one side of the bottom of the casing to increase the humidity of the exhaust gas entering the casing.

[0013] A flow guiding structure is provided on one side inside the housing. The flow guiding structure includes a flow guiding plate provided on one side inside the housing, a connecting shaft rotatably connected to one side of the top of the housing, a half gear fixed on the outside of the connecting shaft, and a reciprocating assembly provided on one side of the half gear.

[0014] Dust collection electrodes are installed on both sides inside the housing, and discharge electrodes are installed on both sides of the dust collection electrodes;

[0015] A fine filter screen is installed on one side inside the exhaust port.

[0016] Through the above technical solution, an electric field is generated by energizing the discharge electrode and the dust collection electrode, causing the dust to move and deposit towards the dust collection electrode. The purified gas is further filtered through the fine filter screen in the exhaust port and then discharged. The dust that falls is collected through the ash hopper. The second drive motor is started to cause the ash discharge blade to guide the dust inside the ash hopper into the ash discharge pipe. The first drive motor drives the spiral blade shaft to rotate, and the dust is discharged from the ash discharge pipe.

[0017] Furthermore, the reciprocating assembly includes a guide shell fixed to one side of the top of the housing, a toothed plate slidably connected inside the guide shell and meshing with the half gear, a movable sleeve mounted on one side of the toothed plate, a stepper motor mounted on the top of the housing, and a crank mounted on the end of the stepper motor output shaft and slidably connected with the movable sleeve.

[0018] The above technical solution uses a stepper motor to drive the crank to rotate, which in turn causes the moving sleeve to drive the gear plate to reciprocate. At the same time, the half gear drives the connecting shaft, connecting pipe and guide plate to swing back and forth, which guides the exhaust gas entering the casing and makes it more evenly distributed.

[0019] Furthermore, the spray structure includes a diversion pipe installed on one side of the top of the housing, a rotary joint installed on the top of the diversion pipe, a solenoid valve installed on one side of the diversion pipe, a water inlet pipe installed on one side of the solenoid valve, a connecting pipe installed on the top of the rotary joint and rotatably connected to the housing, and atomizing nozzles installed at both ends of the connecting pipe.

[0020] The above technical solution introduces water from the inlet pipe into the diversion pipe by opening the solenoid valve. Then, the water is atomized and sprayed out through the atomizing nozzle, increasing the humidity of the exhaust gas. At the same time, the connecting shaft drives the connecting pipe to swing back and forth, expanding the coverage of the atomizing nozzle and improving the spraying effect.

[0021] Furthermore, the connecting shaft extends into the interior of the housing and connects to the connecting pipe, and the connecting pipe forms a rotating structure with the diverter pipe through a rotary joint.

[0022] The above technical solution enables the connecting shaft to drive the connecting pipe to rotate flexibly, and when the connecting pipe swings under the drive of the flow guiding structure, it does not affect the water supply from the diversion pipe.

[0023] Furthermore, the guide plates are symmetrically distributed along the vertical center line of the connecting pipe, and the guide plates and the connecting pipe are welded together as an integrated structure.

[0024] The above technical solutions prevent airflow from deviating to one side and ensure that exhaust gas is evenly distributed within the casing. The welded integrated structure prevents the guide plate from loosening or falling off during long-term oscillation.

[0025] Furthermore, the atomizing nozzles are arranged at equal intervals on both sides of the connecting pipe, and the connecting pipe is connected to the diverter pipe through a rotary joint.

[0026] The above technical solution enables water mist to evenly cover the waste gas flow area, significantly increasing the humidity of the waste gas and improving the dust agglomeration effect.

[0027] The above-described solution of this utility model has at least the following beneficial effects:

[0028] This invention utilizes a stepper motor to drive a crank to rotate, which in turn causes a moving sleeve to drive a toothed plate to reciprocate. Simultaneously, a half-gear drives a connecting shaft, connecting pipe, and guide plate to oscillate back and forth. This achieves the airflow guidance function of the device, allowing dust to be fully charged and captured in the electric field, preventing dust from escaping due to excessively fast local airflow, thereby improving the overall dust removal effect.

[0029] This invention introduces water from the inlet pipe into the diversion pipe by opening the solenoid valve. The water is then atomized and sprayed out through the atomizing nozzle, increasing the humidity of the exhaust gas. At the same time, the connecting shaft drives the connecting pipe to swing back and forth, thereby realizing the rotating spray function of this device. This allows the water mist to mix fully with the exhaust gas, increasing the humidity of the dust, making it easier to charge and capture, and improving the dust collection efficiency.

[0042] The spray structure 7 is located on one side of the bottom end of the housing 1 to increase the humidity of the exhaust gas entering the housing 1.

[0043] A flow guiding structure 9 is disposed on one side inside the housing 1. The flow guiding structure 9 includes a flow guiding plate 906 disposed on one side inside the housing 1, a connecting shaft 902 rotatably connected to one side of the top of the housing 1, a half gear 901 fixed to the outside of the connecting shaft 902, and a reciprocating assembly disposed on one side of the half gear 901.

[0044] Dust collecting electrodes 12 are installed on both sides inside the housing 1, and discharge electrodes 13 are installed on both sides of the dust collecting electrodes 12.

[0045] Fine filter 17 is installed on one side inside the exhaust port 11.

[0046] In this embodiment of the invention, dust-laden exhaust gas is introduced into the housing 1 through the air inlet pipe 8. An electric field is generated by energizing the discharge electrode 13 and the dust collecting electrode 12, causing the dust to become charged under the action of the electric field and move towards the dust collecting electrode 12 for deposition. The purified gas is further filtered through the fine filter screen 17 in the exhaust port 11 and then discharged. The dust hopper 14 collects the fallen dust. The second drive motor 4 drives one set of dust discharge blades 15 to rotate, guiding the dust inside the dust hopper 14 into the dust discharge pipe 3. The transmission belt 16 links the left and right sets of dust discharge blades 15 to rotate simultaneously to assist in dust discharge. The first drive motor 2 drives the spiral blade shaft 6 to rotate, discharging the dust from the dust discharge pipe 3.

[0047] like Figures 3 to 4As shown, the reciprocating assembly includes a guide shell 904 fixed to one side of the top of the housing 1, a toothed plate 905 slidably connected inside the guide shell 904 and meshing with a half gear 901, a movable sleeve 907 mounted on one side of the toothed plate 905, a stepper motor 903 mounted on the top of the housing 1, and a crank 908 mounted on the end of the output shaft of the stepper motor 903 and slidably connected with the movable sleeve 907.

The connecting pipe 703 forms a rotating structure with the diverter pipe 701 through a rotary joint 702. The guide plates 906 are symmetrically distributed on the vertical center line of the connecting pipe 703, and the guide plates 906 and the connecting pipe 703 are welded together as an integral structure.

At the same time, the toothed plate 905 meshes with the half gear 901, driving the connecting shaft 902 to rotate.

The atomizing nozzles 704 are arranged at equal intervals on both sides of the connecting pipe 703. The connecting pipe 703 is connected to the diversion pipe 701 through the rotary joint 702.

[0050] In this embodiment of the utility model, by connecting the water inlet pipe 705 to the water supply pipe, the water in the water inlet pipe 705 enters the diversion pipe 701 through the solenoid valve 706, and then enters the connecting pipe 703 through the rotary joint 702. The water is then atomized and sprayed out by the atomizing nozzle 704, which increases the humidity of the exhaust gas entering the casing 1, making it easier to capture dust. At the same time, the connecting shaft 902 drives the connecting pipe 703 to swing back and forth, expanding the coverage area of ​​the atomizing nozzle 704 and improving the spraying effect.

[0051] The above description is the preferred embodiment of this utility model.
