Abstract

A dust sensing device is disclosed. The device includes a casing. The casing includes a casing cover and a casing box which are used in match. A gasket is at a connection part between the casing coverand the casing box. The casing cover is at the top of the casing box, is used for closing and opening the casing box, and is provided with fixing connection elements which are fixing bolts. The inside of the casing box is in a cavity state. A gas feeding pipe, a gas discharging pipe, a detector cartridge, an A/D converter, a single chip microcomputer, an electricity storage box, a central processor, a water tank, water pumps and an alarm are disposed in the casing box. The external surface of the casing box is provided with a gas inlet, a gas outlet, a wind turbine, a temperature and humiditydetecting instrument, a display screen, a charging interface and a warning lamp. The front surface of the casing box has a concave surface and a convex surface, the warning lamp and the temperature and humidity detecting instrument are mounted on the convex surface, and the display screen is mounted on the concave surface. The dust sensing device achieves detection of the dust concentration in air, and automatic water mist spraying is performed after the concentration exceeds a standard so as to reduce the dust concentration.

Description

technical field [0001] The invention belongs to the field of sensing devices, in particular to a dust sensing device. Background technique [0002] At present, dust samplers and direct-reading dust detectors are mainly used to measure the dust concentration. The former uses the principle of filter membrane weighing method: a certain volume of dust-laden air is extracted, and the dust is captured on the filter membrane. The increased dust mass, and then use the formula to calculate the dust mass concentration per unit volume of air, which has the disadvantages of troublesome operation and the dust concentration value can only be obtained through calculation; the latter uses indirect methods such as light scattering, β source absorption and other principles. The sampler is calibrated and can display the measured dust concentration value in real time, but the working time is short, the number of measurements is limited, and it cannot continuously monitor the dust, so it can onl...
