Joint 33 is demarcated in described blowback, and its inlet end is communicated with source of the gas, and its outlet side is communicated with negative-pressure pipeline 41; Described sample air-flow gauge 35, it comprises detection part and flow displaying instrument, and detection part is arranged on negative-pressure pipeline 41 place, and detection part is connected with flow displaying instrument by wire.
The utility model overall plan describes as above; Again the utility model overall plan is explained and explained below.
1. composition graphs 1, Fig. 2 and Fig. 3 are described and explain.
2. the gas outlet of High-temperature-resgasant gasant pump NGQB is communicated with air, and air intake opening is communicated with the tail end of negative-pressure pipeline 41.During the powered work of High-temperature-resgasant gasant pump NGQB, continuously from the tail end extracting gases of negative-pressure pipeline 41, the gas of extraction is discharged from the gas outlet of High-temperature-resgasant gasant pump NGQB.Under the decimate action of High-temperature-resgasant gasant pump NGQB, all there is negative pressure condition in negative-pressure pipeline 41, handle tracheae 31a-1, stopple coupon, causes flue gas to be sucked in flue 5 continuously.The flue gas sucked in also samples gas.
3., under the effect of negative pressure, high-temperature flue gas is extracted and becomes sample gas; Sample gas, in the process of advancing, if run into the low object of temperature or gas, just there will be condensation, namely forms condensing drip or condensation acid droplet etc.Therefore, technical measures of the present utility model are as follows:
After sample gas enters stopple coupon, first through the handle tracheae 31a-1 of sampling handle 31a, next enters the head end of negative-pressure pipeline 41 and continues to advance, and then goes to the negative-pressure pipeline 41 of sensor CGQ position.In the path of aforementioned walking, the object all needing guarantee sample gas to touch, parts are not low temperature; In other words, in the path of aforementioned walking, object, parts that sample gas touches, all take heating and isothermal holding, a lot of introductions and explanation in addition after concrete condition.Note: for the temperature of flue gas, normal temperature also belongs to low temperature category.
Because sample gas does not touch the gas of the object of low temperature, the parts of low temperature and low temperature, so do not possess the condition generating condensation, therefore, there is not the situation such as condensing drip, condensation acid droplet in portable flue gas measurement mechanism of the present utility model.
4., in order to make sample gas not occur the situation such as condensing drip, condensation acid droplet, the utility model takes heating and thermal insulation measure to negative-pressure pipeline 41 and to the handle tracheae 31a-1 in sampling handle 31a.Specifically: " this three from inside to outside order is arranged for negative-pressure pipeline 41, negative pressure zone of heating 41a, negative pressure heat preservation thermofin 41b "; " this three from inside to outside order is arranged for handle tracheae 31a-1, handle zone of heating 31a-2, handle heat insulation layer 31a-3 ".
Zone of heating, such as electric heating layer, can produce heat after its energising.Electric heating layer conventional electrical heating elements as electrical heating wire, electric heating film, etc.The effect of heat insulation layer is that few heat that allows distributes as far as possible.
In the utility model, negative-pressure pipeline 41 and handle tracheae 31a-1, the temperature of this both temperature and sample gas, as much as possible close to as well, so then avoids the technique effect occurring condensing drip, condensation acid droplet best.
5. cabinet type flue gas measurement mechanism is in order to produce negative pressure, usually uses the ejector of movement-less part.The advantage of ejector is long working life, resistant to elevated temperatures very capable; Shortcoming is that produced negative pressure is stable not, and needs adapted pressure regulator valve and compressor.The advantage of High-temperature-resgasant gasant pump NGQB is that produced negative pressure is more stable, can not adapted pressure regulator valve, shortcoming is that mission life is relatively short, but the working time of portable flue gas measurement mechanism is all very short, each with regard to one, two hour, can use many times in the life of product of High-temperature-resgasant gasant pump NGQB.
Further, the resistance to elevated temperatures of High-temperature-resgasant gasant pump NGQB has certain restriction, and working temperature can not exceed the value of regulation, and in addition, the lower mission life that can extend product of temperature, is therefore also provided with cooling element in the utility model device.One of feature of the present utility model is: before cooling element, sample gas be made as far as possible to maintain original temperature and do not fall; After cooling element, sample gas be made as far as possible significantly to decline, be beneficial to High-temperature-resgasant gasant pump NGQB life.For cooling element, after also have much detailed introduction and explanation.
6. negative-pressure pipeline 41 is to the position at sensor CGQ place from head end, needs heating and thermal insulation to avoid occurring the situation such as condensing drip, condensation acid droplet; But the sample gas in negative-pressure pipeline 41 has arrived High-temperature-resgasant gasant pump NGQB air intake opening place, whether there is the situation of condensation herein, be just no longer a problem.The sample gas at High-temperature-resgasant gasant pump NGQB air intake opening place does not only need to keep high temperature, is wish that sample temperature degree herein can be as well lower on the contrary; Sample temperature degree is herein higher, then the high temperature resistant grade selected of High-temperature-resgasant gasant pump NGQB is higher, serviceable life is shorter; Too high temperature, is even difficult to choose the air pump can being competent at this high temperature resistant grade.
So, on negative-pressure pipeline 41, select where to terminate heating and insulation? theory and practice all proves, the position of end should be selected in: crossed sensor CGQ position place; If just terminate heating and insulation in the position at sensor CGQ place, then herein or herein near there will be condensation, and then affect the normal work of sensor CGQ.So the end of heating and insulation: the position between sensor CGQ and High-temperature-resgasant gasant pump NGQB.
The content more than introduced may be summarized to be: the further situation that described negative pressure zone of heating 41a and negative pressure heat preservation thermofin 41b is arranged on negative-pressure pipeline 41 is: this two-layer head end starting from negative-pressure pipeline 41, this two-layer end position between sensor CGQ and High-temperature-resgasant gasant pump NGQB.
7. detector is the instrument carrying out flue gas inspection.In the utility model, detector also claims measuring unit CLDY.Detector comprises Displaying Meter and sensor CGQ.Sensor CGQ comprises: the circuit such as part, and amplification, shaping of popping one's head in.The information of acquisition is sent to Displaying Meter by sensor CGQ, the gas station that Displaying Meter display is current detected.
The utility model is recommended: for Displaying Meter and sensor CGQ, use sizing, specification, complete property; So, no longer can consider intermediate circuit, as interface circuit, change-over circuit, match circuit etc.The Displaying Meter of sizing, specification, complete property and sensor CGQ, the electric signal that its sensor CGQ exports directly is sent to Displaying Meter and uses, and is shown
Probe part can be the gas station being positioned at negative-pressure pipeline 41, finding out pipe; Also can be perforate on negative-pressure pipeline 41, although probe part main body is positioned at outside negative-pressure pipeline 41, the gas station in pipe can be found out by perforate; A kind of situation is also had to be that measuring cell structure is set separately in the body portion of negative-pressure pipeline 41, at the probe part of measuring cell sensor installation CGQ or sensor CGQ.This measuring cell is equivalent to negative-pressure pipeline 41 herein, its diameter is thicker, and the measuring cell left side have input the sample gas of coming in from stopple coupon, outputs the import of sample pneumatic transmission toward High-temperature-resgasant gasant pump NGQB on the right of measuring cell; Measuring cell is externally airtight, and sample gas flow velocity when measuring cell position is slack-off, but the general direction of flowing is still from left to right, is carry out under the suction of negative pressure.
8., in the utility model, negative-pressure pipeline 41 should from broadly understanding, that is: negative-pressure pipeline 41 length can set as required; Negative-pressure pipeline 41 can be a pipe, also can be to be linked in sequence by several pipe head and the tail to form, and the diameter of each root pipe is unequal is also fine.
The feature 1 of negative-pressure pipeline 41: head end is communicated with the outlet side of handle tracheae 31a-1, the inlet communication of tail end and High-temperature-resgasant gasant pump NGQB.The feature 2 of negative-pressure pipeline 41: during normal testing, sample gas at the suction order side of negative pressure to flowing, from the head end of negative-pressure pipeline 41 to the end parts of negative-pressure pipeline 41.
Measuring cell, when implementing, if be provided with measuring cell, can be considered as special a section of negative-pressure pipeline 41 by the utility model.
9. zone of heating can use heating, as used heating wire.Use 220V alternating current, also can use the safety low-voltage electric of 24V, etc.
10. use the stopple coupon that two joints are above, the meaning is exactly: can be two joint stopple coupons, also can be three joint stopple coupons, four joint stopple coupons, or more stopple coupon.
11. when routine, and sampling handle 31a should manufacture and design for there being housing; Handle tracheae 31a-1, handle zone of heating 31a-2, handle heat insulation layer 31a-3, this three is all arranged in housing.But when not having housing, only jug tracheae 31a-1, handle zone of heating 31a-2 and handle heat insulation layer 31a-3, also can practical function, principle, but obviously perfect not.Use the sampling handle 31a not having housing, not only use inconvenience, and handle heat insulation layer 31a-3 is easily damaged, more go into seriously further, if handle zone of heating 31a-2 uses 220V alternating current, also there is potential safety hazard.
12. explanations connected about changeable.
The utility model device is a kind of portable device, and in device, the length dimension of each object is little of certainly considering to get, if a certain object size is oversize, carry inconvenience, that is just with portable inconsistent.But the flue diameter dimension of fuel-burning power plant is all very large, if the size of sampling object falls short of, just cannot be drawn to the flue gas of flue central part or other target site.Therefore, the stopple coupon 31-1 of two joints or more, they are added just can reach required length; But, when transport, wish that again stopple coupon 31-1 is shorter, with Portable belt.
So when Test Field uses, the connection of each stopple coupon 31-1 is that a kind of changeable connects.Usually, use portable flue gas measurement mechanism to only have one or two hour at the scene, detect complete, also stopple coupon 31-1 will be drawn in, diminishes in the hope of length dimension.During transport, length dimension can diminish, and during use, length dimension can become large, and this connected mode of stopple coupon 31-1 is referred to as changeable and connects by us.The methods can carrying out changeable connection are a lot, below specifically for four kinds of examples.
A. need connect both, the link of one is set to internal thread, and the link of one is set to external thread in addition, both threaded engagement, tightens, just achieves connection when both occur relatively to rotate forward; Otherwise, when both relative reverse rotation occur, just achieve dismounting.
