High efficiency air filter device and operating method thereof

An air filter device and an operating method thereof. The air filter device comprises an air filter system and a powder distribution system. The air filter system comprises an air filter chamber (1), a clean air chamber (2), and a high-pressure jet pulse powder cleaning device (3). An entrance of the air filter chamber (1) is in communication with an air inlet pipe (4); an exit of the clean air chamber (2) is in communication with an air outlet pipe (6), and the air outlet pipe (6) is in communication with an exhaust fan (9). A plurality of bag filters or filter cartridges (10) are disposed in the air filter chamber (1). An opening end of each of the bag filters or filter cartridges (10) is in communication with the clean air chamber (2), and high-pressure jet pulse powder cleaning devices (3) are disposed above the opening end of the corresponding bag filters or filter cartridges (10). The powder distribution system includes a powder storage tank (13), which is in communication, via a powder delivery tube (15), with the air inlet pipe (4) of the air filter chamber (1). The operating method comprises a first powder distribution step and a second powder distribution step, which are respectively performed according to pressure detection status of the air filter chamber (1).

Two-stage garbage incinerator

A two-stage garbage incinerator is characterized in that secondary air supply holes are arranged on front and rear arches of a furnace body and an ignition combustion-supporting hole is arranged on the rear arch; a grate in the furnace body is divided into two stages from top to bottom; the upper stage is a forward pushing stage and the lower stage is a backward pushing stage; an independent primary air chamber is arranged below each stage; the heads of the grates on the forward pushing stage face the low point direction of the grates; the heads of the grates on the backward pushing stage face the high point direction of the grates; moving beams of the grates on the same stage are equipped with left and right draw bars arranged side by side; the left and right draw bars are supported by supporting roller devices and are connected with the moving beams to form draw bar frames; and the ends of the draw bar frames are connected with front rocker arm driving mechanisms, lateral rocker arm driving mechanisms or front straight driving mechanisms. The incinerator can realize full drying of the whole garbage material, ensure complete combustion and ensure the garbage incineration effect and hot ignition loss rate. At the same time, the incinerator has less spare parts and spare part specifications, good quick-wear part interchangeability and low manufacture and maintenance costs.

Sensor system for measuring and monitoring indoor air quality

An apparatus for accurately sensing room conditions and positioned in the air stream to the return air plenum. The apparatus is a combination of a temperature and volatile organic compound (VOC) sensor. The sensor module is built into a ceiling grid system with the body of the sensor module extending into the return air plenum. The ceiling grid has a slot fabricated into its face which allows the air stream from the room to flow by the sensors on its way to the plenum. This enables both the temperature and the composition of the air to be monitored at the optimal location. A portable pollution sensor device that measures and monitors leading indicators of indoor air quality and the extent of pollution is used in conjunction with the ceiling grid mounted sensor modules. The portable device documents and benchmarks air quality both in buildings under construction and in existing buildings. The portable device is network-enabled so as to simultaneously transmit the data to various control devices. In addition to its use to monitor areas not otherwise covered by the ceiling grid mounted sensors, the hand-held sensor can be used during building construction to determine the best locations in the ceiling grid system for mounting of the fixed pollution sensors.
