Description

Technical field:

[0001] The invention relates to a dust-removing device for purifying water-insoluble dust sources. Background technology:

[0002] The current devices that use water curtain dust removal have an unreasonable dust-water mixing method and a low purification rate. The effect of eliminating water mist by only using a water baffle at the air outlet is also not ideal. A large amount of water mist is discharged through the fan outlet, which not only causes a waste of water for dust removal, but also causes secondary pollution. Therefore, the field needs a dust removal device that uses a water curtain to capture dust with a high purification rate, intercepts water mist at the fan outlet for good external spraying effect, has less water waste and is energy-saving. Summary of the invention:

[0003] The present invention aims to provide a technical solution that meets the current needs of the field, and its main technical features are: a dust inlet elbow with a dust inlet is installed on the lower left side of the shell and is connected to an air balancing hood in the shell, a plurality of air balancing plates with a certain air balancing angle are fixed in the air balancing hood, the air balancing hood opening is 100 to 200 mm away from the partition, an air guide plate is fixed on the upper part of the partition, a rotating drum with a plurality of long mixing arc plates is fixed above the air guide plate and below the flow port through a pair of side bearing seats and a long axis, a water spray cross pipe with a plurality of water spray holes is fixed below the center line of the rotating drum through a water spray branch pipe passing through the shell, the water spray holes are directly opposite to the long mixing arc plates, a water spray solenoid valve is installed on the water spray branch pipe outside the shell and then connected to the water supply main pipe; the water supply branch pipe connected to the water supply main pipe is connected to the water supply main pipe. After the water supply solenoid valve is installed on the pipe, it passes through the shell and is connected to the annular nozzle with multiple water spray holes on the outer surface through the flow port and the fixed cover; one end of the suction pipe passes through the bottom plate and is connected to the suction port of the high-pressure water pump, and the other end of the suction pipe passes through the fixed cover and is placed in the filter cylinder below the center of the annular nozzle, and then the filter cylinder is fixed under the fixed cover; one end of the high-pressure water pipe passes through the bottom plate and is connected to the water outlet of the high-pressure water pump, and the other end is connected to the water spray cross pipe with multiple horizontal water spray holes; a water inlet guide plate with an inclined guide plate is fixed in the middle under the bottom plate, and a plurality of equal flow guide plates with a certain angle are fixed under the inclined guide plate. Multiple layers of waterproof panels are equidistantly fixed on the inner side of the shell and the side of the water inlet guide plate. The first layer of waterproof panels is 120 to 150 mm away from the surface of the dust-dissolving water. The waterproof board in the middle is fixed on the first layer of waterproof board with four fixing columns at equal distances. There are buffer water absorption layers under all waterproof boards. The speaker suction cover is fixed to the bottom of the air outlet position of the bottom plate with bolts through the flange ring. The buffer water absorption layer is installed in the speaker suction cover. The bearing seat is fixed to the center of the speaker suction cover through a bracket. The other end of the fan shaft with fan blades at one end is fixed under the bearing seat in the speaker suction cover. The windward surface of the fan blade is fixed with a water absorption layer and should be higher than the inner air intake port. The fan with motor F is fixed on the bottom plate of the air outlet through a flange ring. The fan outlet is connected to the air outlet tube with lower air outlet and upper air outlet through an air outlet elbow. A buffer water absorption layer is fixed inside the air outlet tube. The bearing seat is fixed to the center of the air outlet tube with a bracket. The other end of the fan shaft with a fan blade at one end is fixed to the inner sleeve of the bearing seat in the air outlet cylinder, and a water absorption layer is fixed on the windward surface of the fan blade; a high-pressure water pump with a motor D is fixed on the bottom plate through a flange ring, an inner flange frame is fixed at the upper position of the shell, the bottom plate is fixed on the inner flange frame, and after the upper hole on the upper cover is sleeved on the upper air outlet, the upper cover is fixed on the flange frame, the main sewage pipe with a sewage valve is connected to the main water tank through the bottom of the shell, and one end of the shower chamber sewage pipe with a time control valve is connected to the front shower chamber through the bottom of the shell, and the other end is connected to the main sewage pipe. There is a base under the shell, and the control unit controls the water supply solenoid valve, the water spray solenoid valve, the sewage valve, the time control valve, the liquid level meter, the motor F and the motor D through the control cable, and the power cable provides power to the device.When the current water spray chamber spray time reaches the set value, the time control valve opens once to discharge the dust-containing water inside into the main sewage pipe. The drum with a long mixing arc plate can rotate quickly under the action of wind force and the dust-dissolving water sprayed from the water spray cross pipe. The multiple equal flow guide plates on the inclined guide plate below the water inlet guide plate are to enable the dust-containing air and dust-dissolving water passing through this position to be fully mixed, forming a uniform dust precipitation effect. A buffer water-absorbing layer waterproof plate is fixed below the multiple layers at equal intervals to capture and absorb the water mist sprayed along the air, and the water mist is blocked in the water-absorbing layer. The water mist forms liquid water and flows back to the main water tank under the action of its own weight. The fan blades in the horn suction cover and the air outlet rotate under the action of the airflow generated by the fan to generate centrifugal force, and the liquid dust-dissolving water in the water-absorbing layer below the fan blades is thrown into the buffer water-absorbing layer on the side wall, and then flows into the main water tank.

[0004] The technical effect achieved by the technical solution provided by the present invention is achieved as follows: the control unit controls the water supply solenoid valve to open, and supplies dust-dissolving water to the main water tank through the water supply branch pipe and the annular nozzle. At the same time, the dust-dissolving water sprayed from the water spray hole of the annular nozzle sprays off the precipitation and attached impurities on the filter cylinder. When the water level of the dust-dissolving water reaches the liquid level meter, the liquid level meter sends an alarm signal, and the control unit closes the water supply solenoid valve, starts motors F and D, and makes the fan and high-pressure water pump work. At the same time, the water spray solenoid valve can also be opened, and the sewage valve is in a closed state. The dust-containing air enters the front water spray chamber from the dust inlet, the dust inlet bend pipe and the wind hood. The dust-containing air is evenly sprayed from the wind hood port into the front water spray chamber under the action of the wind hood plate in the wind hood. After being sprayed by the water spray cross pipe and rotated and stirred by the long mixing arc plate, most of the dust in the air is captured in the front water spray chamber. The high-pressure water pump sucks up the dissolved dust water from the filter cylinder in the main water tank, pressurizes it, and then sprays it out. The dust-containing air coming from the flow port is purified again by spraying. The air containing a small amount of dust is captured and purified by the dissolved dust water in the main water tank. The flow-equalizing guide plate on the inclined guide plate subdivides and evens out the dust-containing air entering the main water tank, so that the dust in the air is captured by water at a higher rate. The air with water mist first passes through multiple layers of equidistant waterproof plates with buffering water absorption layers to absorb and capture the water mist. The high-speed airflow drives the fan blades in the speaker suction cover and the air outlet to rotate. The water absorbed and captured in the water absorption layer on the windward side of the fan blade is thrown into the buffering water absorption layer on the side wall under the action of centrifugal force. The dissolved dust water in the buffering water absorption layer condenses into liquid water, and the liquid dissolved dust water flows into the main water tank under the action of gravity. This technical solution has a good effect of recycling water mist, and uses the airflow and the flow of dust-dissolving water to drive the long mixing arc plate to rotate and stir the dust in the air, so that the dust is fully in contact with the dust-dissolving water and flows into the front water-spraying chamber with the dust-dissolving water, so it has an energy-saving effect. After the dust-dissolving water has been used for a period of time, the control unit will open the drain valve to discharge the dust-dissolving water containing too much dust precipitation, and at the same time, the water supply solenoid valve can be opened to clean the filter cylinder. When and how long the time-controlled valve under the front water-spraying chamber is opened is controlled by the control unit. When the water-spraying solenoid valve is opened for a period of time, the control unit opens the time-controlled valve when the water level under the front water-spraying chamber is too high; the flow rate of the water-spraying solenoid valve and the volume control unit under the front water-spraying chamber can determine when the time-controlled valve is opened. The control unit determines how long to open the time-controlled valve according to the flow rate of the time-controlled valve to discharge the dust-dissolving water containing dust precipitation in the front water-spraying chamber. The control unit controls this device through a control cable.

[0005] The present invention has a compact structure, good centrifugal mist capture effect, obvious water saving, and multi-stage spraying with high dust purification efficiency in the air. Compared with the existing technical solutions, this technical solution is novel, creative and practical, and will surely be widely used in the field of environmental protection dust removal.
