Abstract
The utility model provides a plurality of flue gas thief holes constitute that take flue observation window of standard thief hole is by brickwork, observation door, first hinge, slagging scorification sampling gate, A second hinge and different diameter. The observation door is connected with the brickwork through first hinge, arranges on the observation door that a slagging scorification sampling gate and a plurality of structure are the same, nevertheless flue gas thief hole not of uniform size. Wherein the slagging scorification sampling gate passes through A second hinge and is connected with the observation door. Observation door flue gas thief hole department has arranged and has taken internal screw thread circle hole, has the glossy nut of external screw thread and inner wall and passes through the screw and is connected with the observation door, and sealing filler has been arranged in bottom combination department of circle hole on nut and observation door, through extrusion the sealing up of realization sampling gun of packing. The flue gas thief hole uses the end cap to plug up the entrance to a cave in non - sample period. It is sealed to adopt take flue observation window of standard thief hole to realize when extracting the flue gas or get the slag specimen experiment, improves experiment accuracy nature, reduces the boiler and leaks out.
Description
Technical field
This utility model relates to field of thermal power, is specifically related to the flue observation window in a kind of band standard sample hole.
Background technology
Flue observation window is requisite ingredient in boiler flue, is mainly used in observing the Slagging etc. of heat exchanger in burner hearth fire situation, flue.Owing to boiler sealing when mounted is preferable, and inside furnace wall, all it is disposed with water-cooling wall, when needs carry out extracting flue gas to boiler, obtain the experiments such as slag specimen, generally also carries out at observation window.Observation window length and width is generally respectively greater than 400mm and 200mm, and during extraction flue gas, sampler is the thinnest (less than 20mm, but specification is different), when stretching into the devices such as sample probe at observation window, due to negative pressure during boiler operatiopn, large quantity of air can be made to be inhaled into flue.And when obtaining slag specimen, for the Slagging that simulation boiler is actual, sample probe diameter generally keeps consistent with Tube Sheet of Heat Exchanger diameter, it is also only about 50mm, there is also bigger hole.On the one hand the flue gas being inhaled into can affect the degree of accuracy of experiment extraction flue gas, affects the flue gas flow field of observation window region, on the other hand also can increase exhaust gas volumn, and then reduce boiler efficiency.
Summary of the invention
Leaking out for solving existing flue observation window in a large number and affect experimental precision and reduce the defect of boiler efficiency using to carry out existing in experimentation, the purpose of this utility model is to provide the flue observation window in a kind of band standard sample hole.
To achieve these goals, this utility model adopts the following technical scheme that the flue observation window in a kind of band standard sample hole, including furnace wall 1, observes door the 2, first hinge 3, slagging scorification sampling gate the 4, second hinge 5 and multiple smoke sampling holes 6 of different-diameter.
Described observation door 2 is connected with furnace wall 1 by the first hinge 3, arranges that a slagging scorification sampling gate 4 and multiple structure are identical observing on door 2, but smoke sampling hole 6 not of uniform size, wherein slagging scorification sampling gate 4 is connected with observing door 2 by the second hinge 5.
Being disposed with the circular hole of band female thread 7 at described observation door 2 smoke sampling hole, with external screw thread 9, the nut 8 of inner wall smooth is connected with observing door 2 by screw thread, and on nut 8 with observation door 2, bottom circular hole, junction is disposed with airtight and watertight padding 10.
Described smoke sampling hole 6 uses plug 11 to be blocked at hole at non-Proper Sampling Period.
Compare with existing common view ports, the flue observation window in this utility model a kind of band standard sample hole arranges a slagging scorification thief hole on observation door and organizes the smoke sampling hole that diameters are different more, can avoid leaking out in carrying out experimentation, improve experimental precision, reduce by leaking the decline of wind-induced boiler efficiency.
Accompanying drawing explanation
Fig. 1 is the front view of the flue observation window in this utility model a kind of band standard sample hole.
Fig. 2 be this utility model a kind of band standard sample hole flue observation window in the side view in smoke sampling hole.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further details.
As shown in Figures 1 and 2, the flue observation window in a kind of band standard sample hole that this utility model provides includes furnace wall 1, observes door the 2, first hinge 3, slagging scorification sampling gate the 4, second hinge 5 and multiple smoke sampling holes 6 of different-diameter.
Observe door 2 to be connected with furnace wall 1 by the first hinge 3, arrange on door 2 that a slagging scorification sampling gate 4 and multiple structure are identical observing, but smoke sampling hole 6 not of uniform size, wherein slagging scorification sampling gate 4 is connected with observing door 2 by the second hinge 5.Observing the circular hole being disposed with band female thread 7 at door 2 smoke sampling hole, with external screw thread 9, the nut 8 of inner wall smooth is connected with observing door 2 by screw thread, and on nut 8 with observation door 2, bottom circular hole, junction is disposed with airtight and watertight padding 10.Smoke sampling hole 6 uses plug 11 to be blocked at hole at non-Proper Sampling Period.
