Description
Technical field
The present invention relates to on-line continuous automatic monitoring technical field, more particularly to one kind is rapidly heated heated type flue gas sampling
Feeler lever.
Background technology
Minimum discharge refers to coal fired boiler of power plant during generator operation, end treatment etc., using multiple pollutant
Efficient cooperation-removal technology Based on Integrate System.End treatment is mainly by the way of wet desulphurization+high efficiency demister ＆ wet scrubbers
Reduce the concentration of emission of particulate matter.
Discharge flue gas after cooperation-removal processing has that pollutant concentration is low, flue-gas temperature low (below dew point), flue gas are wet
The characteristics of degree high (supersaturation)；Particulate matter humidity high viscosity easily causes to block in the easy fouling of sampling feeler lever inwall by force, while flue gas
In drop serious measurement interference is produced to measuring instrument, cause measurement inaccurate or even damage measuring instrument.For such cigarette
Gas is needed to carry out heat pre-treatment before measuring, and flue-gas temperature is heated to more than flue gas dew point measuring again；Existing
Sensor is all disposed within the front end of thief rod by heated type flue gas sampling feeler lever as temperature sensor, is directly connect with flue gas
Touch, because particulate matter humidity high viscosity is strong, can equally cause transducer distortion, equally, it is necessary to which sampling feeler lever possesses fast heating
Ability, avoid sampling inside pipe wall gather to form fouling.
The content of the invention
The purpose of the present invention is, it is necessary to for the discharge after cooperation-removal processing according to above-mentioned the deficiencies in the prior art part
Flue gas is quickly heated, and in order to reach the purpose of the present invention, the present invention realizes one kind heated type flue gas that is rapidly heated and adopted
Sample feeler lever, it is characterised in that including probe tube, protection outer tube, protection middle pipe, heat insulation foam, heater strip；Described probe tube is set
In the inside of described protection middle pipe；Teflon coatings are scribbled in the inner tubal wall of described probe tube；In described probe tube
Spiral type groove is set on outer tube wall；Described heater strip is embedded in spiral type groove；In described protection outer tube and described
Protection middle pipe between heat insulation foam is set.
The exit of probe tube described further is longitudinally inserted into a temperature sensor；Set in the import of described probe tube
Put a sampling mouth that can be changed；It is helicitic texture that mouth, which is sampled, with described probe tube.
One polytetrafluoroethylene (PTFE) circle is set between temperature sensor described further and the longitudinal cross-section of probe tube；Described
Temperature sensor connects temperature controller；Temperature controller controls the temperature of heater strip.
Protection outer tube described further and described protection middle pipe and ring flange are to be welded and fixed structure；Described sampling
Pipe is through ring flange；One groove is set on described probe tube, is embedded in two fixed blocks in semicircle shape in a groove, it is described
Fixed block and with ring flange using being screwed, form the demountable structure of described probe tube.
Probe tube described further, protection outer tube, the material of protecting middle pipe are Stainless steel 316.
Multiple bolts hole are symmetrical arranged on ring flange described further.
The technical effects of the invention are that after high humility ash-laden gas is by probe tube, temperature, which is rapidly heated to, to be set
Constant temperature degree (more than flue gas dew point), supersaturated drop rapid vaporization in flue gas, particulate matter adhesiveness reduce, can effectively avoid adopting
Sample inside pipe wall gathers to form fouling.Exist after heat-treated in flue gas without aqueous water, effectively prevent liquid water droplets to measurement
As a result interference.
