Abstract
The utility model discloses a smoke and dust density automatic detector, which is used for air pollution and used conveniently by the households with emission of smoke and dust. The user can test the density of smoke and dust at any time, and can judge whether the standard is met or not; and can easily construct a remote control system for monitoring the density of smoke and dusty. The utility model has the advantages of simple structure and low production cost; and the utility model comprises a bracket. The two ends of the bracket are provided with a transmitting head and a receiving head, both of which are used for being matched. The room between the transmitting head and the receiving head is provided with a control circuit and a power supply; wherein, the control circuit is connected with an indication clock. The utility model makes use of optoelectronic conversion principle to let the smoke dust gas pass between the transmitting head (or light source) and the receiving head (or optical signal receiver). Since the smoke dust granules in the gas can absorb light, hamper the light beams and diffuse light intensity, the optical signals which are received by the optical signal receiver become weakened to some extent, and then the signals are exported and converted into the digital expressions on the indicators such as a clock-type pointer or a digital clock to judge whether the density of smoke and dust is far from the standard or not.
Description
Technical field
The utility model relates to a kind of detection instrument, relates in particular to the dust concentration autodetector of a kind of atmospheric pollution aspect.
Background technology
Dust concentration automatic monitoring system of the prior art, its principle and complex structure, the cost height, the general user can not use, and the remote online automatic monitoring system costs an arm and a leg especially, reaches hundreds thousand of units, is difficult to popularize.
Summary of the invention
The purpose of this utility model provide a kind of conveniently have the soot emissions user use, can test at any time its discharging dust concentration whether up to standard, build up long-range dust concentration on-line continuous monitoring system, simple in structure, cheap dust concentration autodetector easily.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of dust concentration autodetector comprises: support is characterized in that: the support two ends are separately installed with matching used emitting head, receive head, are connected with control circuit and power supply between emitting head and the reception head, are connected with indicating gauge on the control circuit.
The utility model utilizes photoelectricity transformation principle, allow flue dust gas between emitting head (being light source) and reception head (being optical signal receiver), pass through, because the soot dust granule absorbing light in the gas, and stop light and disperse light intensity, the light signal that optical signal receiver is received weakens to some extent, and then with the output of its signal, and the numeral that changes indicating gauges such as tabular form pointer or digital table into shows, judge with this whether dust concentration exceeds standard, simple in structure, cheap.
