Provided is a coal-containing wastewater spraying device for dust suppression during coal conveying, including a motor, a gland, a body seat, and an accelerator. The body seat includes a funnel-shaped cover, a first disc and a plurality of crushing plates. The accelerator includes a circular second disc. The end of an output shaft of the motor passes through the first disc to connect with the second disc. The cover is provided with a water retaining ring between the first disc and the second disc along its axial direction. The cover, the first disc, the second disc and the water retaining ring form a water inlet space.

A sprinkler system for a temporary chute used for disposal of construction materials during a construction or renovation project. The sprinkler system is releasably engaged with the temporary chute and is used to control dust within the chute, wash down the chute, and extinguish fires. A housing of the sprinkler system is releasably engaged with an intake hopper of the chute, placing an interior chamber of the housing in fluid communication with the chutes' tunnel. First and second sprinkler heads are located within the interior chamber. The first sprinkler head is temperature sensitive and automatically actuated when a threshold temperature is crossed. The second sprinkler head is manually activated by an operator to spray liquid into the tunnel to control dust or wash the interior surfaces of the chute. The sprinkler system and temporary chute are disengaged from the building once the construction or renovation project is completed.

A spray trough is described herein, including a trough body, wherein the trough body has a bottom portion, a first side portion, a second side portion, a front portion, and a back portion, the bottom portion, the front portion, and the back portion each having a first end and a second end, a top plate having a first end and a second end, wherein the first end of the top plate is fixedly attached to the second end of the back portion, wherein the top plate extends substantially perpendicular from the second end of the back portion, and a deflector plate, wherein the deflector plate is attached to the second end of the front plate, wherein the deflector plate extends downwardly from the second end of the front plate, such that the deflector plate angles towards the front portion.

Provided is a micro-mist suppression device for a coal storage Eurosilo for suppressing dust within the Eurosilo, comprising a micro-mist dust suppression host and a water-gas supply module and a micro-mist generation module connected with the micro-mist dust suppression host; the water-gas supply module includes a water supply unit and an gas supply unit; the water supply unit includes an annular water tank, a variable frequency pump and a water filter which are successively connected, the micro-mist suppression host is connected with the water filter and the variable frequency pump; the gas supply unit includes an air compressor and an air reservoir, the air compressor, the air reservoir and the micro-mist dust suppression host are successively connected; the micro-mist generation module includes a first water-gas hose, a feed assembly and a water-gas distributor which are successively connected, the water-gas distributor is connected with a micro-mist spray head

An injector head for delivering particulate material from a feeder source to a receiver is fitted with a plurality of splitter bars extending generally laterally from the sidewalls thereof into the space through which particulate material is fed as it flows into a receiver. Spray nozzles mounted to said sidewalls below said splitter bars spray coating material generally laterally relative to said sidewalls and generally laterally relative to the length of said splitter bars so as to coat particulate material as it passes over and to the sides and ends of said splitter bars.
