Description

Technical Field

[0001] The present invention relates to an intelligent and efficient cyclone dust collector, and in particular to an intelligent and efficient cyclone dust collector applied in the field of dust collectors. Background Art

[0002] The working principle of cyclone dust collector is to separate dust by using the centrifugal force generated by rotating airflow. It is widely used in many industries such as chemical, pharmaceutical, food processing, cement and wood processing. However, the efficiency of cyclone dust collectors on the market is not high and the dust removal effect is limited.

[0003] In order to solve the problem of low dust removal efficiency, a cyclone dust collector in the market adopts a wet design and has a certain market share.

[0004] The specification of Chinese patent CN105148676A discloses a wet cyclone dust collector, which includes a housing, a cyclone dust collector, a demisting device, a water inlet device and a sewage discharge device. The housing is mounted outside the cyclone dust collector, the water inlet device is installed on the housing and connected to the cyclone dust collector, the demisting device is installed in the housing, the sewage discharge device is installed in the housing, the cyclone dust collector is provided with an air inlet, and the housing is provided with an air outlet. The exhaust gas is sent into the cyclone dust collector from the air inlet, and at the same time, the water inlet device sends water into the cyclone dust collector. The exhaust gas and water are fully contacted in the cyclone dust collector, and the particles in the exhaust gas adhere to the water and are retained in the water so as to be removed. The exhaust gas after dust removal is discharged from the air outlet after the water mist is removed by the demisting device.

[0005] The specification of Chinese patent CN214437678U discloses a spray-type cyclone dust collector, which sets a uniform air chamber at the bottom of the cyclone barrel, and first guides the flue gas entering the cyclone barrel into the uniform air chamber through a guide block, so that the flue gas gathers in the uniform air chamber and tends to be stable, and then rises, so that the particles in the flue gas absorb the spray liquid, and then the flue gas flow rate is increased through the cyclone plate, and the spray liquid with absorbed particles is thrown toward the wall of the cyclone barrel under the action of gravity, so that the impurity liquid flows to the bottom of the barrel to achieve the purpose of dust removal.

[0006] Although existing dust collectors all have a defogger function that can effectively reduce the dust content in the gas, the water content of the gas after spraying is also high, which wastes water resources, and it is impossible to know whether the dust content of the discharged gas meets the emission standards. Summary of the invention

[0007] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to improve the gas dust removal efficiency.

[0008] In order to solve the above problems, the present invention provides an intelligent and efficient cyclone dust collector, comprising a dust chamber 1, a dust chamber 2 and a water-gas separator placed in parallel, the internal structures of the dust chamber 1 and the dust chamber 2 are the same, and the dust chamber 1 is connected with an air intake hood, the interiors of the dust chamber 1 and the dust chamber 2 are both provided with left and right chambers, and an isolation plate is fixedly connected between the two chambers, and the lower parts of the two chambers are simultaneously connected with a lower hopper, the two chambers of the dust chamber 1 and the dust chamber 2 are both installed with a spray pipe, and a dust recovery tank is placed below the dust chamber 1, the dust chamber 2 and the water-gas separator , and a conveyor belt is installed in the dust recovery trough, the water-gas separator includes a box body, and two groups of backwashing filters are installed symmetrically inside the box body, the box body is located below the backwashing filter The inner wall is fixedly connected with a separation plate, and the bottom of the box body is connected to a hopper, and the inner wall of the box body between the two groups of backwashing filters is fixedly connected with a partition, the upper end of the box body is connected to an air outlet hood, and a fan is installed at the end of the air outlet hood away from the water-gas separator, the air outlet end of the fan is connected to a Y-shaped discharge pipe, and a dust detector is installed at a position of the fan close to the Y-shaped discharge pipe.

[0009] In the above-mentioned intelligent and efficient cyclone dust collector, multi-pass water mist dust removal is used to effectively improve the dust removal efficiency, and a water-gas separator is used to recover water. In addition, a dust detection device is set at the discharge port to ensure that the gas meets the emission standards.

[0010] As a further improvement of the present application, the Y-shaped discharge pipe includes a straight discharge pipe and a return pipe, and the return pipe is connected to the straight discharge pipe, and the return pipe is connected to the air intake hood on the dust removal chamber through a pipeline, and the connection point between the straight discharge pipe and the return pipe is rotatably connected with an exhaust damper, and the rotation center point of the exhaust damper is located at the intersection of the straight discharge pipe and the return pipe, and the inner wall of the return pipe is fixedly connected with a damper controller, and the other side of the damper controller is fixedly connected to the exhaust damper. The dust detector detects the gas after dust removal. If the dust content meets the emission standard, the gas is directly discharged into the atmosphere through the straight discharge pipe. If the dust content of the gas does not meet the emission standard, the exhaust damper is controlled to close the straight discharge pipe, and the gas is sent back to the dust removal chamber through the return pipe for re-dust removal.

[0011] As a further improvement of the present application, the gate controller includes a plurality of concentrically rotatably connected shaping keels, and a covering cover is fixedly connected between each two adjacent shaping keels, and an electrostrictive rod is also fixedly connected between the inner walls of the two outermost shaping keels, and the dust detector is electrically connected to the electrostrictive rod through a control processor. Under normal emission conditions, the exhaust gate closes the opening leading to the return pipe. When the dust detector detects that the dust content in the gas is higher than the set threshold, the electrostrictive rod is energized, and the electrostrictive rod extends after being energized, thereby pushing the shaping keel to expand to a larger angle, thereby pushing the exhaust gate to rotate and close the opening leading to the straight exhaust pipe, so that the gas that does not meet the emission standards is sent back through the straight exhaust pipe for dust removal.

[0012] As a further improvement of the present application, the shaping keel is made of high-strength material and the covering cover is made of elastic material. The shaping keel plays the role of expanding and pushing the exhaust gate to rotate, so it must be made of high-strength material. The covering cover plays a rebound role, so it is made of elastic material.

[0013] As another improvement of the present application, a filter is also fixedly connected to the inner wall of the return pipe, and the filter includes a positioning frame with an opening at the upper end, and a combined filter element is inserted into the inner wall of the positioning frame, and a magnetic strip is fixedly connected to the upper end of the combined filter element, and the magnetic strip is magnetically attracted to the positioning frame, and a socket matching the magnetic strip is provided on the side wall of the return pipe facing the magnetic strip, and the return pipe can also be directly connected to the outside atmosphere, so that the gas does not need to be sent back to the dust removal, which can effectively improve the dust removal efficiency. Under this premise, the gas that does not meet the emission standards will be further filtered by the combined filter element when passing through the return pipe, so as to ensure that the gas meets the emission requirements, and the combined filter element is inserted into the positioning frame and positioned by the magnetic strip, so that the combined filter element can be easily removed and replaced.

[0014] As another improvement of the present application, the combined filter element includes a fixed frame, filter screens are fixedly connected on both sides of the fixed frame, and dehumidifier is filled between the two filter screens. A liquid collecting chamber is opened on the inner wall of the lower end of the fixed frame, and a liquid return port is opened on the side wall of the liquid collecting chamber facing the dehumidifier. A pressure sensor is installed at the bottom of the liquid collecting chamber, and an alarm electrically connected to the pressure sensor is installed on the magnetic strip. The gas is filtered by a double-layer filter screen to effectively improve the dust removal effect, and the dehumidifier is used for dehumidification. The dehumidifier becomes liquid after absorbing water and flows into the liquid collecting chamber under the action of gravity, which is convenient for centralized collection and processing. When the liquid collecting chamber is almost full of water, the pressure sensor will trigger the alarm in advance to remind according to the detected pressure.

[0015] In summary, two dust removal chambers are set up to carry out water mist dust removal, which effectively improves the dust removal efficiency, and a water-gas separator is used to separate water and gas, so that water is recycled and reused, effectively saving water resources. A dust detector is added at the exhaust port to detect the gas after dust removal. When the dust content of the gas meets the emission standards, it is directly discharged into the atmosphere through a straight discharge pipe. When the dust content of the gas does not meet the emission standards, the flow direction of the gas is changed through the exhaust gate. On the one hand, the gas can be re-dusted, and on the other hand, the combined filter element can be used to filter the gas again to meet the emission requirements. BRIEF DESCRIPTION OF THE DRAWINGS
