Proposed is an equipment for reducing specific air pollutants generated from heated asphalt concrete with proportional control, which includes: a dryer for heating and drying aggregates and for burning harmful gases introduced through nozzles mounted thereon; a first dust remover for removing dust from the harmful gases emitted from the dryer; a fine dust remover for filtering fine dust from the remaining gases and dust; a bypass damper for returning some of the gases and dust emitted from the first dust remover to a second dust remover; the second dust remover for filtering the dust in the gases and dust emitted from the first dust remover; and a blower for feeding the gases exhausted from the second dust remover to the dryer, wherein clean gas exhausted from the fine dust remover is emitted to the air through an exhaust fan and a stack.

A reflective particulate material comprises a particulate substrate, and a coating on the particulate substrate. The coated reflective particulate material may have a relative error of an amount of the coating on the particulate substrate of about 5% to about 15%, and/or a dust index of about 5 or lower, and/or a staining loss of about 8% to about 11%. A method of manufacturing the reflective particulate material comprises mixing the particulate substrate with a liquid coating composition to form a wet particulate mixture, passing the wet particulate mixture through at least one heat zone to remove water and/or moisture, and curing the coating material in the coating composition.

An environmentally-friendly feed drying and cooling integrated machine, comprising a material drying unit, a material cooling unit and a gas treatment unit, wherein the material drying unit comprises a drying box group (1) and a heating box body module (2); the heating box body module (2) is used for carrying out a drying treatment on materials in the drying box group (1); the material cooling unit is connected to the drying box group (1), receives the materials from the drying box group (1), and carries out a cooling treatment on the materials; two ends of the gas treatment unit are respectively connected to the drying box group (1) and the material cooling unit; the gas treatment unit receives gas discharged from the drying box group (1), carries out a temperature reduction and dehumidification treatment on the gas, and then conveys the gas to the material cooling unit.

A continuous dryer heat exchanger device has a plurality of heat exchanger units. Waste air of an associated dryer section of the associated continuous dryer is guided through an individual heat exchanger unit and contaminants from the waste air are deposited in the heat exchanger unit. A cleaning device for cleaning the continuous flow heat exchanger device of the contaminants is thereby provided, which cleaning device has a plurality of cleaning units. An associated heat exchanger unit is to be cleaned by means of the individual cleaning unit. A switching device is provided, by means of which the cleaning units are to be switched in series one after the other.

A material drying and cooling integrated machine, comprising a heating module, a drying module, a dust removal filter module, a temperature-lowering and dehumidifying module, and a cooling module. Dry hot air generated in the heating module can enter the drying module to dry materials; the temperature-lowering and dehumidifying module can conduct temperature lowering and dehumidification on air entering the interior thereof so as to form dry cold air, and the dry cold air can enter the cooling module to cool materials in the cooling module; the dry hot air enters the drying module to dry the materials in the drying module, then damp hot air is formed, and part of the damp hot air can be heated by the heating module again; the other part of the damp hot air can sequentially pass through the dust removal filter module and the temperature-lowering and dehumidifying module, and dry cold air can be formed.

A back-blowing unblocking device for the dustproof screen of the dryer, a dustproof equipment, and a dryer are provided. The back-blowing unblocking device for the dustproof screen of the dryer utilizes a closed compartment space of the dryer. The back-blowing unblocking device for the dustproof screen of the dryer includes a high-pressure air main pipe, a high-pressure air horizontal pipe, high-pressure air branch pipes, a shunt connecting pipe, and back-blowing fan-shaped nozzles. A length of each high-pressure air branch pipe is equal to a length of an A-shaped dustproof screen. Both ends of the each high-pressure air branch pipe are closed and an upper center opening is welded to the shunt connecting pipe. Both sides of the each high-pressure air branch pipe are densely arranged with the back-blowing fan-shaped nozzles.

A lint catching system is provided for a clothes dryer. The lint catching system filters lint from exhaust air expelled from the clothes dryer.
