Description
Technical field
The utility model relates to the anti-deblocking technology of volume measuring pipe, refers to especially the anti-blocking measurement mechanism of a kind of continuous coverage air quantity, surge.
Background technology
Air quantity, surge measurement generally directly lead to instrument from measuring mouth, carry out measurement and monitoring.In unit starting and normal sampling line in service, enter fuel oil product and a large amount of dust, and react with sulfur, in sampling line, form higher hardness and high-adhesion material, sampling line is stopped up.Because pipeline is longer, manually regularly with pressurized air, positive and negative sampling line is dredged again, effect is bad, often cannot blow logically, and wastes time and energy.
Existing pressure obtaning device and dust emissions device only have two impulse joints, and secondary precipitate chamber volume is little, and by nut manual drain.Under pressure flange, deashing rod effect is little, high rigidity and high-adhesion material are not acted on, and can not stop dust to enter measurement pressure guiding pipe, and the time is slightly long, and deashing rod can wearing and tearing break thoroughly ineffective.Current this measurement mechanism failure rate is many, and especially plugging reason is outstanding, need to carry out technology innovation processing.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of anti-blocking blowback sampler, to solve existing serious blockage problem.
For solving the problems of the technologies described above, the utility model concrete scheme is as follows:
A kind of anti-blocking blowback sampler, is arranged in induced draft fan flow, surge sampler pipeline, comprising: source of the gas distributor box, 2 sampler, solenoid valve, electrotimer, break-make device and gas source pipe road, wherein, sampler comprises: rotating metallic sheet, collection tube to be arranged and pressure pipe; Described source of the gas distributor box is communicated with collection tube to be arranged by source of the gas pipeline, described rotating metallic sheet is arranged on the middle and lower part of collection tube to be arranged, described pressure pipe is arranged on the source of the gas pipeline of collection tube to be arranged top, described solenoid valve and the electrical connection of break-make device are arranged in the source of the gas pipeline on sampler top, described electrotimer and the electrical connection of break-make device.
Further, described back-blowing device can also increase extension spray lance, and extension spray lance is arranged on pressure pipe.
Further, described in described sheet metal has an intermediate shaft to run through to be fixed on, on collection tube cylindrical shell to be arranged, rotating metallic sheet can rotate along axle.
Further, described in collection tube to be arranged be that a cylinder adds a funnel-shaped structure, cylindrical portions diameter is greater than the diameter of described source of the gas pipeline.
Further, described pressure pipe and surface level angle are α, 20 °≤α≤60 °.
The beneficial effect of technique scheme of the present utility model is as follows:
The utility model, by design sheet metal effectively blocks dust enter gauge pipe, solenoid valve is regularly opened, and will assemble dust and purge totally, has ensured that the continuity of measuring point is interference-free, raising boiler operatiopn security.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The problem that the utility model stops up for existing measurement sampler, provides a kind of efficient quick anti-blocking blowback sampler.
As shown in Figure 1, introduce blowback wind regime one from compressed-air actuated source of the gas distributor box, with the stainless-steel tube of PFP-B-II type Φ 14 to Φ 16 as source of the gas pipeline, connect the source of the gas distributor box gas source interface of anti-blocking blowback sampler and the collection tube to be arranged of sampler, the installation of the collection tube to be arranged of two sampler will ensure that vertically collection tube to be arranged is vertically mounted on pipeline or equipment as far as possible.Described rotating metallic sheet has an intermediate shaft to run through to be fixed on collection tube cylindrical shell to be arranged.
Locate to install pressure pipe at stainless-steel tube above near collection tube to be arranged, pressure pipe and surface level angle are °-50 °, α=40, one be malleation side another be suction side.Extension spray lance is arranged on pressure pipe, can extend and be bent to local instrument (10 meters of left and right) far away, facilitates instrument maintenance.The angle of described extension spray lance and surface level should be 50 °-60 °.
In normal measuring process, gas sampled is from device bottom enters, the dust being mingled with sheet metal stop with turning effort under, utilize the centrifugal decline feature of dust, major part is gathered on collection tube to be arranged, thereby the pressurized air of controlling by electrotimer control break-make device purges in short-term, and dust is blown back in flue, avoid dust to enter in instrument measurement pipeline (being pressure pipe and extension spray lance) and cause obstruction, cause and measure extremely.Described power of electromagnetic valve is provided by the solenoid valve box of solenoid valve peripheral hardware, and solenoid valve, break-make device and electrotimer are all contained in solenoid valve box, and solenoid valve is by the control of break-make device, thus the break-make of control blowback wind regime.
Utilize the feature that dust is larger than specific gravity of gas, the gas that contains dust is through two-layer anti-jamming mechanism (being sheet metal and blowback source of the gas), convection current layer by layer, separates dust layer by layer, and the dust after separation is collected in collection tube to be arranged, can blow down voluntarily eliminating dust with timing solenoid valve, thereby reduce and reduce the dust entering in sampling line, effectively reduce sampling dust, greatly reduce line clogging situation and occur, introduce again blowback source of the gas, can ensure the long-time normal operation of sampling line.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
