Description
【Technical field】
The utility model relates to heat power equipment technical field, and more particularly to one kind is advantageous to improve particle concentration monitor survey
The flange protection device of accuracy of measurement.
【Background technology】
At present, China some areas haze weather takes place frequently, and atmospheric environment faces a severe challenge.Only 2016, Beijing was sent out altogether
Raw heavily contaminated weather 39 days, wherein ozone heavily contaminated 1 day, remaining 38 days are PM2.5 (pellet) heavily contaminated.According to money
Material shows, average annual 73 micrograms of the concentration/cubic meters of Beijing PM2.5 in 2016, more than national standard (35 micrograms/cubic meter) 109%.
Under sustainable development policy, current Environmental Protection in China department pays much attention to environmental problem, and particle content in waste gas discharges in enterprise
It is the important indicator of environmental administration's monitoring, each dust-laden exhaust gas discharges enterprise, all should install particle according to state's laws laws and regulations requirement
Thing concentration monitor instrument, pollutant emission situation is measured in real time.At present, particle concentration monitor table is widely used to each work
Industry field, such as electric power, chemical industry, cement, factories and miness, steel field etc..The measurement data of particle concentration monitor is blowdown enterprise
The real-time monitoring of industry, charges for disposing pollutants clearing, the important evidence of environmental protection punishment.Therefore, the measurement accuracy of particle concentration monitor with
The personal economic interests of enterprise and social image are closely bound up.
In recent years, improved constantly with the standard of environmental regulation, enterprise's exhaust gas particle thing emission limit gradually reduces.Such as
From 1 day January in 2015, new edition《Fossil-fuel power plant atmospheric pollutant emission standard》Particulate matter in flue gas is discharged in regulation, thermal power plant
Content must not exceed 30mg/m3.And thermal power plant's minimum discharge mark criterion calls particle content must not exceed 10mg/m3, somely
The emission limit in area is even lower.The particulate matter of such low concentration in accurate measurement flue gas is wanted, to the measurement accuracy of measuring instrument
It is it is required that very high.
The measurement object of particle concentration monitor is typically industrial discharged waste gas, complicated component in waste gas, is often contained
The compositions such as a large amount of vapor (or other gas vapors).By taking the discharge flue gas in thermal power plant as an example, wherein containing 8% to 12%
Vapor.The mounting flange of particle concentration monitor is that particle concentration monitor is connected with the key on exhaust pipe road
Part, have the characteristics that low cost, good airproof performance, installation are simple, be widely used.Currently used gas particles thing concentration prison
The common mounting flange of instrument is surveyed, does not configure heater and insulation material, mounting flange exposes in an atmosphere.Because flange is short
Pipe one end is connected with particle monitoring instrument, and the gas fluidity in short tube in local space is poor, is higher than in the temperature of tested gas
In the case of environment temperature, the gas in flange short tube will be radiated by short tube outer wall, in short tube temperature will close to environment temperature,
The temperature in flange short tube is caused to be less than the temperature of flowing gas in tested flue.As in the winter time, it is tested when environment temperature is less than
During the dew-point temperature of the vapor (or other steams) in gas, contained vapor will condense into flange short tube internal gas
Small water droplet.Under liquid tension effect, several small water droplets and the particulate matter of the suspension in tested gas are combining, and are formed
" the bulk droplet " of several times bigger than single particle.This " bulk droplet " is relatively large in diameter, and the scattering process to laser is than single
Particulate matter is stronger, therefore the nephelometric turbidity unit of laser increases in flange short tube, causes meter measurements higher than actual value.Actually should
With middle discovery, particle concentration monitor measured value virtual height, the even exceeded situation thus triggered is relatively common.Therefore, carry
The measurement accuracy of high particle concentration monitor is significant.
