Abstract
The invention discloses an automatic environment air quality monitoring system. The automatic environment air quality monitoring system comprises an air inlet pipe, wherein the air inlet pipe is connected with a filter; the filter is connected with a vacuum tank; the filter is arranged on a weighing device; the vacuum tank is provided with an air pump; one end of the air pump is communicated to the vacuum tank and the other end of the air pump is connected with an inserting pipe; the inserting pipe is inserted into the lower part of a water level in a water storage tank; an exhausting pipe is inserted into the upper part of the water storage tank; the bottom end of the exhausting pipe is located above the water level in the water storage tank; and a dehumidifier and a flow meter are arranged on the exhausting pipe. With the adoption of the technical scheme, the concentration of solid particles of a monitored smoke dust region can be calculated through simple equipment. When gas passing through the filter enters the water storage tank, sulfur dioxide is absorbed and then the gas enters the dehumidifier to remove moisture in the exhausted gas; and the quantity of the exhausted gas can be monitored through the flow meter.
Description
Technical field
The present invention relates to a kind of atmosphere quality automatic monitor system, belong to environmental monitoring technology field.
Background technology
A lot of dust, fine particle, sulphuric dioxide, oxides of nitrogen, acid deposition etc. can be produced when smelting APT (ammonium paratungstate) solid slag.The severe contamination of environment can be caused in these soot emissions to air.In modern industrial society, the pollution of flue dust causes the attention of people, is thus necessary to carry out real time on-line monitoring to the dust concentration in the flue of industrial pollution source emission.Current great majority adopt the opaque method of optics.Such metering system sensitivity is not high, requires high to beam path alignment degree, and installs complicated time-consuming.Given this, Chinese patent literature CN202757883U provides a kind of Smoke Monitoring System, comprise light source, receive camera lens, light hurdle, sensor, wherein, described light source, described reception camera lens and described smooth hurdle are positioned at the side of emission source successively, and described dust concentration monitoring device also comprises: pre-service and power controller, the modulator be electrically connected with described pre-service and power controller, the amplifier be electrically connected with described modulator, the detuner be connected with described amplifier electric, and described pre-service and power controller have two terminals, terminal reception is from the signal of described light source, another terminal reception is from the signal of described sensor.System that employs backscattering principle, light source, reception camera lens and light hurdle are positioned at the side of emission source successively, the light that light source sends is irradiated to emission source from side, thus only need single-ended installation, without the need to optical path pair, and by the mechanical vibration of flue and the impact of the uneven beam wobbling caused of the uneven refractive index do not caused of flue-gas temperature.But, do not have a kind of monitoring system can not make optically to monitor the concentration of flue dust in prior art.
Summary of the invention
Therefore, the object of the invention is to overcome defect of the prior art, provide a kind of and do not make optically to the system that the flue dust produced when smelting APT solid slag is monitored.
To achieve these goals, a kind of atmosphere quality automatic monitor system of the present invention, comprises draft tube, and described draft tube is connected with filtrator, and described filtrator is connected with vacuum tank; Described filtrator is arranged on weighing device, described vacuum tank is provided with air pump, one end of described air pump is communicated in described vacuum tank, the other end connects an intubate, described intubate is inserted into the water surface bottom in a water tank, the top of described water tank is inserted with gas outlet, and the bottom of described gas outlet is arranged in above the described water tank water surface, described gas outlet is provided with a dehumidifier and flow meter.
Described draft tube is provided with valve.
Described weighing device comprises electronic scales.
Described valve is solenoid valve, and described solenoid valve, electronic scales and air pump are connected with control system.
The exhaust port side of described gas outlet is provided with sulphuric dioxide detecting device.
Adopt technique scheme, a kind of atmosphere quality automatic monitor system of the present invention, first the termination of draft tube is placed in monitored flue dust region, control system Controlling solenoid valve is opened, negative pressure in vacuum tank then absorbs the air in monitored flue dust region, air enters filtrator by draft tube and is filtered by solid dust particle, cleaned air after filtration enters vacuum tank, when the air pressure in vacuum tank is consistent with ambient pressure, then vacuum tank no longer absorbs air, the now constant weight of filtrator, the difference of the initial weight and final weight that calculate filtrator by electronic scales is exactly the weight W of the solid dust particle that filtrator adsorbs, and the volume V of vacuum tank is constant and known, the concentration of the solid particle in monitored flue dust region then can be calculated by the ratio of W and V.After this process is complete, control system Controlling solenoid valve is closed, and controls air pump and vacuumize, and can carry out next round monitoring after vacuumizing.Enter water tank by the gas after filtrator sulphuric dioxide is absorbed, then enter dehumidifier by the moisture removal in Exhaust Gas, the quantity of emission gases can be monitored by flowmeter.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
