Description
Technical field
The utility model relates to a kind of atmosphere quality automatic monitor system, belongs 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.
Utility model content
Therefore, the purpose of this utility model is to overcome defect of the prior art, provides a kind of and does 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 utility model, 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 utility model, 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 utility model.
Embodiment
Below by way of the drawings and specific embodiments, the utility model is described in further detail.
As shown in the figure, the present embodiment provides a kind of flue dust on-line monitoring system, comprises draft tube 1, and described draft tube 1 is connected with filtrator 2, and described filtrator 2 is connected with vacuum tank 3; Described filtrator 2 is arranged on weighing device 4, described vacuum tank 3 is provided with air pump 5, one end of described air pump 5 is communicated in described vacuum tank 3, the other end connects an intubate 7, described intubate 7 is inserted into the water surface bottom in a water tank 8, the top of described water tank 8 is inserted with gas outlet 9, and the bottom of described gas outlet 9 is arranged in above described water tank 8 water surface, described gas outlet 9 is provided with a dehumidifier 10 and flow meter 11.
Described draft tube 1 is provided with valve 6.
