Abstract
The utility model relates to an inserted flue gas flowmeter. In general, a flue gas pipeline has a large size without an enough installing straight-pipe section, the conventional flow measuring device can not normal meter, the measured flue gas medium has the main characteristics of high temperature, low flow speed and large dust-containing concentration, and the conventional flow measuring device can be plugged to not normally measure. The inserted flue gas flowmeter comprises a detecting rod inserted to the measured pipeline, wherein the detecting rod is connected with a force and electricity converting element connected with a transfer circuit, the detecting rod is connected with a fixed housing through a supporting seat, the transfer circuit is connected with the force and electricity converting element in the fixed housing through a conducting wire, and the fixed housing is welded with the measured pipeline. The inserted flue gas flowmeter has the advantages of concise and convenient installation and easy construction, saves cost and can also ensure the measuring precision.
Description
One, technical field:
The utility model relates to a kind of flowmeter, especially relates to a kind of plug-in smoke gas type flowmeter.
Two, background technology:
Because environmental protection requirement at present, all needs to measure for discharged flue gas in the oriented atmosphere of institute, has following problem in metering:
1. the flue stock size is very big, does not have enough installation straight lengths, and the normal flow measuring device can't normally measure.
2. the principal feature of tested flue gas medium is the temperature height, flow velocity is low, dust content is big, the normal flow measuring device can result in blockage and can't normally measure.
Three, utility model content:
The utility model provides a kind of installation succinct, convenient in order to solve above-mentioned weak point, and construction is very easy to, and has both saved cost, can guarantee the plug-in smoke gas type flowmeter of measuring accuracy again.
For achieving the above object, the technical solution adopted in the utility model is: a kind of plug-in smoke gas flowmeter is characterized in that: comprise the test rod that inserts tested pipeline, test rod is connected with the power electric transition element, and power electricity conversion elements is connected with translation circuit.
Described test rod is connected with fixed housing by supporting seat.
Described translation circuit is connected with power electric transition element in the fixed housing by lead.
Described test rod be shaped as circle or rectangle.
Described fixed housing and tested pipeline welding.
Compared with prior art, the advantage and the effect that the utlity model has are as follows:
1. the utility model has utilized test rod as the flow velocity conversion element, because it can pass whole cross section and test the speed, can obtain the measurement of the mean flow rate of pipeline easily.
2. the utility model adopts the plug in construction design, and it is convenient to have an installation, and the advantage that use cost is lower thoroughly solves the measurement difficult problem of flue gas flow.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model.
Description of reference numerals: 1-test rod, 2-tested pipeline, 3-fixed housing, 4-supporting base 5-power electric transition element, 6-translation circuit.
Five, embodiment:
Referring to Fig. 1, a kind of plug-in smoke gas flowmeter, comprise fixed housing 3, being provided with cross sectional shape in the fixed housing is the test rod 1 and the power electricity conversion elements 5 of circle or rectangle, test rod stretches out shell and inserts in the tested pipeline, translation circuit 6 is connected with power electric transition element 5 in the fixed housing by lead, and test rod 1 is connected by supporting seat 4 with fixed housing 3, fixed housing 3 and tested pipeline 2 welding.The utility model adopts a stock as the flow rate detection element, since during media flow to the impact of test rod, be arranged on test rod top impulsive force is passed to the power electric transition element, the electric signal of this power electric transition element output is handled through translation circuit, is converted to the normalized current signal of can teletransmission carrying.
The utility model is mainly used in the metering and the test of the flue gas flow of various large-scale pipelines, is particularly suitable for the system for desulfuration and denitration flue gas flow and measures, and has thoroughly solved the difficult problem of low flow velocity, medium containing dust flow.
Use the detailed process of this measurement device flue gas to be: to open the circular hole that a size is about 120mm at pipeline, will install and insert in the pipeline, determined direction and position,, and guarantee sealing with welding flange and pipeline welding; After the device installation, make instrument in running order after the energising, confirm that flow is zero in the pipeline, at this moment, to carrying out zero clearing the zero point of instrument, the state of can devoting oneself to work after finishing.When flue gas flows through, because fluid is to the impulsive force of test rod, make capable electric transition element with detected signal, giving change-over circuit handles, and the required 4～20mA current signal of output system, the DCS system converts except that the flow size of tested flue gas according to mathematical model according to this signal magnitude, and system carries out flow demonstration or control according to the flow size.
Because it is shorter that straight length is installed, and causes the Flow Field Distribution inequality, use test rod to carry out fluid-velocity survey, can realize flow rate detection to unlimited multiple spot, guarantee average measurement to whole cross section flow velocity, guarantee measuring accuracy.
