Description
Technical field
This utility model is related to transmitter technical field and in particular to a kind of anti-blocking, corrosion-resistant, resistant to elevated temperatures miniaturization cigarette
Road differential pressure measurement device.
Background technology
Known, pressure transmitter can be used for measuring flue high temperature, burn into dampness and the gas pressure containing a large amount of solid impurities
Power, is then converted into the current signal output of 4-20ma dc.Flue differential pressure measurement device in the market adopts method
Blue bellows is installed and is adopted pressure mode, also has Pipe installing to adopt pressure mode.Because high temperature, burn into dampness and a large amount of solid fly
The presence of dirt, is very easy to the phenomenons such as diaphragm deformation, burn into breakage and line clogging, leads to measurement pressure inaccurate
Or service life short the problems such as.
Content of the invention
This utility model adopts pressure mode or pipeline in order to solve existing flue differential pressure measurement device using flange film box installation
Pressure mode is adopted in installation, haves such problems as diaphragm deformation, corrosion and line clogging, provides a kind of miniaturization flue differential pressure measurement dress
Put.
This utility model adopts the following technical scheme that a kind of realization: miniaturization flue differential pressure measurement device, including position
Leading portion flue gas pressures measuring unit on fume treatment pipeline and back segment flue gas pressures measuring unit, innovation of the present utility model
Point is that leading portion flue gas pressures measuring unit and the structure of back segment flue gas pressures measuring unit all comprise to be fixed on fume treatment pipe
Measurement arm on road and with fume treatment pipeline insertion, is provided with pressure transmitter, pressure inverting above the measurement arm mouth of pipe
Device bottom is connected with heat abstractor, heat abstractor bottom be fixed on measurement the arm mouth of pipe at, measurement arm inside run through be provided with anti-corrosion
Adopt pressure device, anti-corrosion pressure device lower end of adopting is stretched in fume treatment pipeline, heat abstractor and anti-corrosion adopting turn on simultaneously inside pressure device
It is connected to pressure transmitter.
In order to optimize the structure of this differential pressure measurement device further, improve its function, this utility model has also carried out following
Optimization design:
Described heat abstractor is the radiating tube that outside border offers intensive radiating groove.Intensive radiating groove can play soon
Fast thermolysis, thus reduce the temperature of transmitter measurement end.
Described anti-corrosion adopting press-fits the heavy wall stainless steel tube being set to end in syphon shape, and bend pipe is in 90 ° with vertical direction, edge
Airflow direction is arranged.Anti-corrosion pressure device of adopting adopts pressure heavy wall stainless steel tube, has corrosion resistance, the making of transmitter can be significantly increased
Use the life-span.
Described bend pipe end is provided with downward bevel cuts.The downward bevel cuts in bend pipe end are so that on bend pipe
The liquid condensing also may not flow into inside bend pipe.
When the high temperature in flue, burn into dampness and the gas containing a large amount of solid impurities flow along bend pipe direction, by
The underbalance effect producing flow in gas so that impurity will not enter bend pipe；The downward bevel cuts in bend pipe end so that
The liquid condensing on bend pipe also may not flow into inside bend pipe；Heavy wall pipe corrosion-resistant stainless steel pipe can also be significantly increased transmitter
Service life；On heat abstractor, intensive fin can play quick heat radiating effect, thus reducing transmitter measurement end
Temperature.
Compared with prior art, this utility model structure is simple, reasonable in design, easy to operate, stable performance, according to scene
The handling characteristicss of special environment and design, take particular design in structure so that novel pressure transmitter can be very good to make
In various complex environments, the service life solving pressure transmitter in complicated use environment is short, easy blocking, easily rotten
The drawbacks such as erosion, it is to avoid all defect of traditional flue differential pressure measurement device, have good application value.
