The invention relates to a fluidized bed drying process for ammonium sulfate. The process flow includes that wet ammonium sulfate materials from the upstream are firstly mixed with dried return ammonium sulfate, are pre-dried, then flow into a fluidized bed, are dried and cooled in the fluidized bed, discharged from a discharging port and conveyed to a finished ammonium sulfate bin. Parts of materials dried in the fluidized bed return to a mixing pre-drier, drying air enters a fluidized bed drying chamber after demisting, dust removal, fan pressurization and indirect steam heating, and cooling air enters a fluidized bed cooling chamber after demisting, dust removal, fan pressurization and cooling and demisting through freeze water. Hot air and cold air entering the fluidized bed are converged and exhausted at the top of the fluidized bed, extracted by an induced draft fan after dust removal and demisting through a wet spray washer and a washing tower, and evacuated after further demisted by an outlet demister. A circulating water pump provides washing water and delivers washing liquid. The fluidized bed drying process has the advantages of reasonable setting of the flow, fine operability, controllable material cooling effect, small occupied space of equipment, less project investment and the like.

According to the modular single dust collector of the present invention, with the unit dust removal device and the porous plate, the ash clearing and gas supply of all filtration cylinders in the X direction and the Y direction is respectively achieved, and the ash clearing and dust removal requirements of various dust removal scales and dust collectors with various sizes are achieved; and the modular single dust collector has characteristics of simple structure, substantial cost reducing, easy assembly combination, and effective work efficiency improving.

The invention provides a wet dust collector, and belongs to the technical field of operation. The wet dust collector solves the problem that the moisture content of airflow in an existing wet dust collector is insufficient. The wet dust collector comprises a shell with an inner cavity, the inner cavity of the shell is provided with a water containing area, a dust inlet area and an air outlet area, the water containing area is located at the bottom of the inner cavity of the shell, the dust inlet area and the air outlet area are located above the water containing area, the dust inlet area and the air outlet area are separated through a partition plate, and the partition plate is fixedly connected with the shell; when the washing liquid is contained in the water containing area, an air passing gap is reserved between the bottom edge of the partition plate and the liquid level of the washing liquid; a medium separation structure is arranged in the air outlet area, and washing liquid separated by the medium separation structure can flow downwards along the side face of the partition plate and flow to the air passing gap. Under the action of the high-speed air flow, the flowing washing liquid is crushed into water drops and water mist, so that the content of the water drops and the water mist in the air flow is increased, and the water drops and the water mist can be fully mixed with dust.

The invention discloses a dust removal device for electrical automation equipment. A second motor drives a rotating rod to rotate, and drives a supporting disk to move along the length direction of the screw rod, so that the conduit can move in the vertical direction so as to control the different electrical automation equipment. Dust blowing treatment is carried out in the area, which improves the efficiency of dust removal. At the same time, when the third cylinder is activated, the third cylinder pushes the third push rod to move, so that the conduit moves back and forth in the movable groove, so that several conduits shrink along the diameter of the support plate Or extended, and then can change the dust blowing range of several ducts, and then can flexibly change the working position of the ducts according to the different shapes of the electrical automation equipment, so that the ducts can completely remove dust from the electrical automation equipment, avoiding the long-term accumulation of a large amount of dust that is easy to cause heat dissipation The heat dissipation holes distributed on the board are blocked, which is not conducive to the timely heat dissipation of electrical components, which in turn makes it easy to overheat inside the electrical automation equipment and affect the service life of the equipment.

The invention belongs to the field of streetlamps and particularly relates to a streetlamp capable of removing dust on the inner wall. The streetlamp comprises a lamp pole and a streetlamp mechanism,wherein the streetlamp mechanism is mounted at the top of the lamp pole. The streetlamp utilizes wind energy to automatically remove the dust, and thus the maintenance cost of the streetlamp is greatly lowered; a worker does not need to climb to the top of the lamp pole for maintenance, and thus the possible danger caused by climbing of maintenance personnel is avoided; a centrifugal wheel can identify the magnitude of the wind speed, if the wind speed is small, the centrifugal wheel does not interact with a first rack, a dust removing strip does not play a role of dust removing, and if the wind speed is large, the centrifugal wheel interacts with the first rack, so that the dust removing strip conducts four-time reciprocating motion in a lampshade to complete clearing of the inner wall ofthe lampshade; and the dust removing strip swings leftwards and rightwards while sliding along the bottom of the inner wall of the lampshade under driving of a second rack, so that the stubborn dustin the lampshade is cleared, the dust removing effect in the lampshade meets the dust removing requirement to the maximum extent, and the using effect of the lampshade after dust removing is better.

The invention discloses an adaptively adjusted cleaning robot, which includes a mobile base, a balance adjustment mechanism for anti-collision, a buffer support mechanism for buffer adjustment, an intermediate adjustment seat, an intermittent adjustment mechanism, a transmission console, The cleaning actuator and three transmission mechanisms, the intermittent adjustment mechanism is installed on the middle adjustment seat, and the transmission mechanism drives the intermittent adjustment mechanism to move along the sliding guide column on the middle adjustment seat, the cooperation between the transmission console and the cleaning actuator, Drive the cleaning actuator to perform 0-90°rotation cleaning. The invention uses the structural design of the balance adjustment mechanism to play the role of collision buffer, reducing the collision of obstacles on the robot during walking, and the structural design of the intermittent adjustment mechanism to drive the height adjustment of the cleaning actuator and the adjustment of the horizontal plane angle, and through the transmission The design of the operating table can realize the cleaning of walls at different angles, and has the characteristics of strong adaptability and high cleaning efficiency.
