Abstract
The utility model relates to a process for cement kiln tail gas analysis for dry process high temp. Sampling probe with return device, composed of a high temperature sampling probe 1 and a conveying and return support frame 2, wherein, the filtering medium of a filter has a composite filtering structure with Silicon carbide materials. For the dust whose diameter is larger than 0.3 um, the filtering accuracy can reach 96 percents. Using inner and outer blow blows in combination, a sustain pulse forced purge mode, the dust deposition can be effectively eliminated on the filtering medium. In addition, a probe head tube has a three-layer sleeve pipe structure. Adopting the open type circulating water cooling, the safety of the probe tube used under the condition of the high-temperature is ensured. The conveying and return device is used for the normal maintenance of the sampling probe, in order to ensure the safe operation.
Description
The utility model relates to high temperature (1200 ℃), high dust (2000g/m3) gas sampling device that is used for cement dry method rotary kiln kiln tail process gas analysis usefulness, and particularly a kind of band send the dry method high temperature that returns device sampling probe.
At present, to the gas sampling technique under the high temperature with high dust condition, must effectively solve following technical barrier:
(1) the abundant filtration under the high dust condition requires long-term use continuously not stop up.
(2) the abundant cooling of probe pipe under the hot conditions requires long-term use continuously not damage.
(3) cooling of the filtration of dust and probe pipe should be to carry out automatically under manpower-free's maintenance condition, and higher automaticity is promptly arranged.
Have only the sampling technique of coordinating and resolve above three big technical barriers, be only can be in engineering successful Application, reliably, real effective.
The patent No. is 86107696, name is called that " anti-clogging of ash-laden gas sampling system " and the patent No. are 902125125, name is called two patents of " high temperature with high dust sampling probe ", and the wretched insufficiency part is all arranged technically:
(1) adopts the filter medium of Ni matter powder metallurgy, corrosion-resistant, and sample gas high-moisture and have certain corrosivity often; The anti-clogging effect of cascade filtration is also very limited.
(2) the on-the-spot difficulty of commercial production possesses the condition of the big high pressure N2 of consumption, and its use is limited to.
(3) the cooling problem of probe pipe does not relate to, and the ceiling temperature under the long-term service condition continuously is very limited.
Temperature height when (4) the probe pipe is used can not in time be safeguarded under uncolled situation.
(5) automaticity is low, and the manual maintenance amount is big, is difficult to adhere to for a long time.
(6) can not under the technology of cement kiln tail, use.
The patent No. is 92243452, name is called the technology of " sampling probe that water-cooled, water washing device are arranged ", can be used for dry-process rotary kiln kiln tail, but it exists chilled water to contact with the gas sample and mixes, separate or discharge gas because of water-soluble, cause the low major defect of sampling precision, the dry method sampling technique that this wet sampling technology has generally been adopted in the world replaces.
The purpose of this utility model is to be based upon on the dry method sampling technique by a kind of, can overcome the prior art above shortcomings, is applicable to that the band of cement kiln tail gas sample send the dry method high temperature that returns device sampling probe.
Above-mentioned purpose of the present utility model is to realize by such technical scheme, be that a kind of band send the dry method high temperature that returns device sampling probe, it is characterized in that: by the high temperature sampling probe with send and return bracing frame and constitute, wherein, probe is installed in to send and returns on the bracing frame, send and return bracing frame and have manually or electric driving mechanism, under it drives, pop one's head in and to move axially.
Said structure of the present utility model can further specify by the embodiment that accompanying drawing provides.
The utility model has following accompanying drawing:
Accompanying drawing 1 is a structure composition diagram of the present utility model;
Accompanying drawing 2 is the structure cut-open view of the utility model high temperature sampling probe.
Referring to accompanying drawing 1: band send the dry method high temperature that returns device sampling probe, by high temperature sampling probe 1 with send and return bracing frame 2 and constitute, wherein, probe is installed in to send and returns on the bracing frame, send and return bracing frame and have manually or electric driving mechanism, under it drives, pop one's head in and to move axially.An embodiment of the present utility model is: send the electric driving mechanism that returns bracing frame to be made of sprocket wheel and chain, the probe mounting frame is fixed on the chain, and sprocket wheel makes chain drive probe under the drive of motor and moves axially; In the present embodiment, send to return pressurized air allocation units 3 are installed on the bracing frame 2, it is connected with probe by pipeline.
Referring to the three layer sleeve structure of accompanying drawing 2 high temperature sampling probes of the present utility model for anti-heat expansion shrinkage, its central core is a gas sample passage, outer two-layer be the access way of chilled water, be communicated with cooling water inlet 11 and cooling water inlet 12 respectively; The front end of probe is a sample tap, afterbody is a filter chamber, cooled gas sample is exported by gas sample outlet 9 through filter 6, filtrator is the composite structure of microporosity carbofrax material for adopting medium, the exocoel of filtrator and inner chamber are communicated with outer source purge gas inlet 10 and interior source purge gas inlet 8 respectively, and ring heater 7 is installed on the shell at filtrator place; In order effectively to alleviate deadweight, the diameter of probing shell adopts pre-small post-large variable-diameter structure; In order to reduce the dust that enters probe, adopt streamlined gas sample import 13.
The utility model is owing to the technical characterictic that described structure obtains is as follows with the remarkable result of obtaining:
1. at the anti-blocking technical elements of sampling probe: because the filter medium of filtrator adopts the silicon carbide material of corrosion-and high-temp-resistant, but the dust of filtering＞0.3um reaches 96%; Force the purging mode owing to blow in adopting, can effectively remove the laying dust on the filtration valency matter with blowing the lasting pulse that is harmonious outward; The blowback mode is by the PLC program setting in the sampling switch board 14; Pressurized air regulon 3 has the function of purification of compressed air and switching gas circuit, and it is communicated with source purge gas inlet on the probe by pipeline; Filtrator has the annular electro well heater, because filter medium uses under higher temperature, makes the sample of probe applicable to saturated steam below 80 ℃.
2. aspect the cooling technology of high-temperature probe: the shrinkage structure because three layers of sleeve pipe solar heat protection of probe pipe employing are risen, the water cooling mode of open cycle, the quality of chilled water, temperature, flow are by 14 controls of sampling switch board; The probe pipe adopts the reducing design, effectively alleviates deadweight; The import of streamlined gas sample can reduce the dust that enters the probe pipe; Because described structure, can continuous working under the high temperature with high dust condition after making the probe pipe directly insert the kiln tail.
