Description
Technical field
Dust concentration measure device is the utility model is related to, it is specifically a kind of dense to stationary source minimum discharge flue dust
The device of measure is spent, the measure of the dust concentration under the conditions of the low temperature and high relative humidity that is particularly suitable for use in.
Background technology
Coal-burning power plant's low concentration and the granular material discharged test of minimum discharge, are the difficult points in dust collector performance test.Due to
Current environmental emission standard requires to improve, and dust emission concentration is relatively low, and flue gas belongs to low temperature and high relative humidity state, conventional glass fibers filter
Cylinder easily viscous damage, pollution etc., causes test result accuracy poor.Standard GB/T/T16157-1996《Stationary source is arranged
Particulate matter measure and gaseous contaminant sampling apparatus in gas》With GB/T13931-2002《Particulate matter is surveyed in Concentration in Fixed Pollutants Source
Fixed and gaseous contaminant sampling apparatus》The formulation age is more early, has not applied to low concentration and minimum discharge test.Domestic smoke dust sampling
Instrument disclosure satisfy that the needs of low concentrations of particulates thing test, but smoke dust sampling gun heating function deficiency, cause in test in flue gas
Condensate moisture backflow soaks filter membrane, sharply increase filter membrane resistance, sampling instrument can not normal work, so as to have influence on test result
Accurate reliability.
Utility model content
In summary, perplex to overcome existing sampling gun can not ensure that sampling membrane is not polluted by condensed water, this practicality
It is new by sampling gun electric tracing method, give the measure of the whole power-up heating tape of sampling gun so that filter membrane, filter cylinder be not in sampling process
Influenceed by condensed water, to ensureing that the accurate reliability of test result has good effect.
Technical scheme is used by the utility model：
A kind of gas dust content detection means to stationary source, including aluminum foil and adhesive tape, silicon rubber heat tape, adopt
Sample rifle, power line, temperature sensor probe, temperature controller, automatic smoke dust sampler, breather pipe, power supply, silicon rubber heat tape twine
It is wound on the outer wall of sampling gun；Temperature sensor probe is placed between silicon rubber heating tape and sampling gun；Silicon rubber electrical heating band logical
Cross power line connection temperature controller；Sampling gun connects automatic smoke dust sampler by breather pipe；Temperature controller and automatic smoke dust sampler
It is connected with power supply.
Above-mentioned temperature sensor probe is connected with temperature controller.
Above-mentioned aluminum foil and adhesive tape cladding silicon rubber heat tape.
Operation principle of the present utility model is：
First by winding silicon rubber heating tape in sampling gun outer wall, then silicon rubber heating tape is consolidated with aluminum foil and adhesive tape
It is fixed, while temperature controller is configured, heat tracing temperature is accurately controlled by temperature controller, sampling gun is heated so that it is expected that control companion
Hot temperature is higher than 20-30 DEG C of cigarette temperature, and when heat tracing temperature reaches design temperature, temperature controller shuts off heating power supply, works as heat tracing
When temperature is less than design temperature, the power supply of temperature controller recovery heating.
The beneficial effects of the utility model are：
The utility model has carried out heating to low-concentration sampling device and improved, and passes through the whole winding silica gel electric tracing of sampling gun
Band, and the device of supporting temperature controller, make sampling gun whole process be maintained at certain temperature range, prevent flue gas moisture in sampling gun
Condensation, ensure that filter membrane is not contaminated, make test result accurately and reliably.
The utility model actually uses and checking, and test result is very satisfied, under the conditions of solving low temperature and high relative humidity well
The difficult point of low concentration and minimum discharge tobacco damping-off.
