Continuous progress in science and technology, impel environmental monitoring technology to be developed rapidly, modernization means such as instrumental analysis, computer control has obtained widespread use in environmental monitoring, various automatic continuous monitoring system comes out one after another, and progressively carries out the transition to automatic continuous monitoring from the discontinuity monitoring.Have only and realize that the flue dust continuous monitoring could effectively prevent the generation of flue gas, smoke contamination accident.

Summary of the invention:

The purpose of this utility model provides a kind ofly can carry out the on-line continuous device for monitoring to the parameter such as content, flow, temperature that pollution source discharge flue dust, exhaust gas components.

The purpose of this utility model can realize by following technical measures

This continuous monitoring device is formed by connecting by gaseous contaminant continuous monitor, particle continuous monitor, gas duty parameter measuring appliance and data processing communication and controller.

The purpose of this utility model also can realize by following technical measures

A, described gaseous contaminant continuous monitor comprise that flue gas sampler connects Flue Gas Pretreatment Device, Gas controller, gas analyzer, data Mining and Control Device successively, and the sampling thief blow device that connects sampling thief is connected with the data Mining and Control Device by data cable; B, described particle continuous monitor are made of the data Mining and Control Device and the blow device that are connected with particle monitoring instrument respectively; C, described gas duty parameter measuring appliance are made of the lambda sensor, temperature sensor, pressure transducer, flow sensor and the humidity sensor that are connected with the data Mining and Control Device respectively; D, described data processing communication and controller comprise that the data Mining and Control Device connects demonstration printing device and user by data processing and telecommunication.

The utility model is applicable to industry exhaust gas components content such as thermal power plant, metallurgy, petrochemical industry, building materials, waste incineration, flue dust, flow, the isoparametric on-line continuous monitoring of temperature and calculates.The project that can be used for monitoring has: the conversion concentration of flue gas flue dust, sulphuric dioxide, oxides of nitrogen, mark attitude concentration and discharge capacity; Flue-gas temperature, oxygen level, pressure, flow.Water capacity in the flue gas can be by importing mean value behind the hand dipping.

The utility model is made up of particle CEMS, gaseous contaminant CEMS, Gas Parameters measurement and data acquisition and processing four parts, CO, the SO of the discharging of energy continuous monitoring pollution source ₂, NO _X, the concentration of emission of major pollutants such as flue dust, conversion concentration of emission, discharge capacity and other Gas Parameters, and can by multiple transmission mode with measurement data, have related parameter to be sent to enterprise's Central Control Room and environmental protection administrative authority.The utility model adopts the heat pipe degassing method to measure gaseous contaminant in the flue gas, and gas circuit structure is simple.Major equipment is placed in the pulpit, and its environment for use is better, and is easy to maintenance, stable, safeguards that simply expense is low.This cover system have good dewater, dedusting function, for systems engineering long-term safety, stable operation provide assurance.

The utility model need only one analytic unit can realize continuous monitoring to multiple smoke components linking to each other simultaneously with a plurality of measurement points, the multiple spot multi parameter simultaneous measuring, only an analytic unit of need can be realized the monitoring of maximum 4 kinds of smoke components is comprised NO _x, SO ₂And O ₂And CO (can select measurement parameter) according to user's request.The monitoring function of a plurality of monitoring projects is integrated in the analytic unit, has embodied the developing direction of current fume continuous monitoring system.

The utility model is equipped with semiconductor cooling device to remove the moisture in the gas, adopts the solid particulate matter in the filter dirt technology removal gas, guarantees the reliability of system.Data such as on-line monitoring equipment can be for a long time, continuous monitoring accurately and reliably, record, the concentration of emission that stores and upload various flue gases, flue dust and total emission volumn, by computer network and data processing technique, Monitoring Data concentrated by GPRS pass to environment monitoring and administrative authority.

Description of drawings:

Fig. 1 is the utility model structural principle synoptic diagram;

Fig. 2 is the practical view of the utility model.

Embodiment:

With reference to accompanying drawing, the utility model is made up of four parts, is respectively gaseous contaminant continuous monitor 2, particle continuous monitor 3, gas duty parameter measuring appliance 4 and data processing communication and controller 5.Its workflow is as follows:

Gaseous contaminant continuous monitor 2

Flue gas sampler 6 extracts sample gas from flue 1, by accompanying hot anticorrosion pipeline the sample pneumatic transmission is gone into Flue Gas Pretreatment Device 9, carry out obtaining purer sample gas after the processing such as condensation dewatering and filtering dedusting, sample gas is analyzed through being admitted to gas analyzer 7 behind the Gas controller 10, analyzes the gained data and sends into data acquisition and data Mining and Control Device 19 by signal cable.Because dust in flue gas can often be stopped up sampling head in the actual samples process, so system wants regularly sampling thief 6 to be purged, data Mining and Control Device 19 regularly purges sampling thief 6 by the control to sampling thief blow device 11.

Particle continuous monitor 3

Particle monitoring instrument 12 is directly to insert in the flue, utilizes the back scattering principle that particle content in the flue is measured.Measure the gained data and send into data Mining and Control Device 19 by data cable.Because particle monitoring instrument is optical lens, need uninterruptedly purge it in order to prevent that camera lens is contaminated, blow device 13 is continual to blow a large amount of clean airs as going in the particle monitoring instrument 12.

Gas duty parameter measuring appliance 4

In order accurately to calculate the discharge capacity of pollutant, need accurately measure the oxygen content in the flue, temperature, pressure, flow and humidity.So directly inserted heatproof corrosion-resistant lambda sensor 14, temperature sensor 15, pressure transducer 16, flow sensor 17 and humidity sensor 18 in flue, these sensors change duty parameter into electric signal sends into data Mining and Control Device 19 by data cable.

Data processing communication and controller 5

All electric signal that data Mining and Control Device 19 will collect change digital signal into and import in data processing and the telecommunication 20 by the RS232 cable.Data are stored, handle, tabulate by showing that

printing device

21,22 shows and prints again in 20.Also can data be sent in user's control system 27 by user network.The purpose of native system is for environmental administration monitors foundation as pollution charge in real time to pollution source, so data processing and telecommunication 20 utilize 23 GPRS DTU or CDMA DTU by wireless network data to be sent to environmental administration 25.
