An exhaust gas treatment method by which mercury contained in exhaust gas can be separated and removed efficiently and inexpensively. The method includes cooling an exhaust gas containing mercury in metal vapor phase by spraying water or other methods to condense mercury in the exhaust gas from metal vapor phase into metal liquid and thus to separate and remove mercury from the exhaust gas. When the exhaust gas is cooled by spraying water, the sprayed water is collected and separated into separated water and a solid containing mercury that has condensed to metal liquid, and mercury is recovered from the solid. The metal mercury particles that have condensed to metal liquid are dispersed in cooling water. The metal mercury particles can thus be easily separated and recovered by using a suitable separation device.

Exhaust gas treatment method and treatment facility

A hand dryer device includes nozzles to blow airflows into a hand-placeable drying portion, a blower to generate the airflow to be blown out of the nozzles, a sensor having a light-emitting element to detect the presence or absence of a hand in the drying portion, and a controller to make a hand detection determination of whether the hand is present or absent in the drying portion based on a detection result of the sensor, and control driving of the blower based on a determination result of the hand detection determination. The controller controls an intermittent driving of the light-emitting element of the sensor. In first and second driving cycles of the sensor, when a determination result in the first driving cycle and a first determination result in the second driving cycle differ from each other, the controller extends a driving period of the sensor in the second driving cycle.

Hand dryer device

A hand dryer that includes a capacitance-detection-type proximity sensor structure that detects a capacitance generated in a capacitance detection electrode to detect a presence or absence of an object to be detected, includes a plurality of capacitance-detection-type proximity sensor structures. While one of the capacitance-detection-type proximity sensor structures is in operation, an operation of at least another of the capacitance-detection-type proximity sensor structures is stopped to operate the capacitance-detection-type proximity sensor structures during different periods of time.

Hand drying apparatus

A method of blowing a synthetic resin material into a furnace comprising preparing a synthetic resin material having an average specific surface area of at least 50 m,/kg; and blowing the synthetic resin material from tuyeres of a shaft furnace for ironmaking.

Scrap melting process

A method for blowing a synthetic resin material into a furnace which comprises processing film-shaped synthetic resins into a first granular resin material; crushing non-film-shaped synthetic resins into a second granular resin material; pneumatically feeding the first granular resin material and the second granular resin material to a furnace; and blowing the first and second granular resin material into the furnace.
