Abstract
The utility model relates to a procedure gas-sample analyzing device in a cement dry-process rotary kiln decomposition furnace and a kiln rear, in particular to a heat insulating dry-process high-temperature sampling probe. The procedure gas-sample analyzing device comprises a probe tube and a filter reversing purging unit. A cooling sleeve provided with an air inlet and an air outlet is arranged between the probe tube and the filter reversing purging unit. A cooling chamber is formed and surrounded by the outer walls of the cooling sleeve and the probe tube. The air inlet and the air outlet are communicated with the cooling chamber. Heat isolation is realized between a high-temperature probe tube and the filter reserving purging unit. With adopting a single layer cooling method, the utility model can be operated without any other subordinate devices, thereby having simple structure, convenient operation and maintenance, low cost, good effect of sampling and cooling and prolonged service life and being applicable to the project with low item investment.
Description
Technical field
The utility model relates to the device of a kind of cement dry method rotary kiln dore furnace and the analytical sampling of kiln tail process gas, and particularly a kind of heat is isolated dry method high temperature sampling probe.
Background technology
The process gas of high temperature with high dust is analyzed serial sampling, is the most thorny technical barrier of process analysis procedure analysis engineering, and it is mainly reflected in following 3 points:
(1) furnace high-temperature reaches 1200 ℃ even higher, and the probe pipe that requires probe to put in 1～3m length in the stove can bear this serviceability temperature for a long time and not damage.
(2) the dust-filtering permissible accuracy is also very high, only substantially exceeds the desired 1um dust＜100ug/m of analyser
3, could ensure the ground stable operation of analyser and analytic system long-life thereof.
(3) filtration of dust is born by the filtration and the blowback unit of probe outside stove, needs operation and maintenance, and is only just safer under suitable relatively temperature.
Existing sampling probe, be called as in CN2319805Y, disclosing a kind of name " band send return device in method high temperature sampling probe " utility model patent, the band that it relates to the process gas analysis usefulness that is used for cement kiln tail send the dry method high temperature that returns device sampling probe.By the high temperature sampling probe with send and return bracing frame and constitute.The filter medium of its middle filtrator is the combined filtration structure of silicon carbide material, can reach 96% for the filtering accuracy of＞0.3um dust.Purging and outer the purging combine, continue pulse pressure purging mode in adopting, and can effectively remove the laying dust on the filter medium.In addition, probe Guan Weisan layer sleeve structure adopts recirculated water cooling, the safety of using under hot conditions with the pipe of guaranteeing to pop one's head in.Send and return device and be used for the conventional maintenance of sampling probe to guarantee safe operation.The sampling probe of this structure, can well coordinate and resolve above three big technical barriers, but its three layers of telescopic cooling structure and huge auxiliary equipment thereof, the difficulty that makes that whole sampling probe structure is very complicated, uses and safeguard is big, and the cost height has restricted in the little application of engineering project investment.
Summary of the invention
The purpose of this utility model just provides a kind of heat and isolates dry method high temperature sampling probe, it is coordinating and is resolving under the prerequisite of existing three big technical barriers, the single layer structure that is had, other auxiliary equipments have been saved, sonde configuration is greatly simplified, cost is low, use and safeguard simply, is suitable for the application on the little engineering of project investment.
The purpose of this utility model is to realize by such technical scheme, it includes the probe pipe and is arranged on the terminal filtration blowback unit of probe pipe, be provided with between probe pipe and the filtration blowback unit bring into, the cooling collar of gas outlet, cooling collar surrounds a cooling chamber with the outer wall of probe pipe, and described inlet, outlet is connected with cooling chamber.
Described probe pipe can be on the basis of high temperature alloy, adopts hot-spraying technique to make, have high temperature resistant, anti-washing away and performance such as resistance to oxidation corrosion, thereby has guaranteed probe sampling operation stable under rugged surroundings.
The utility model is work like this: the cold gas source of the gas of the air intake opening on the cooling collar with the external world is connected, the cold gas cooling chamber of flowing through endlessly, sample gas in stopple coupon and the stopple coupon is cooled off, the heat that the cold gas of cooling chamber of flowing through forms is to a certain extent isolated, furnace high-temperature is greatly reduced to the heat transmission of filtering the blowback unit, ensured and filtered the stable and reliability that the blowback unit filters the blowback effect, maintained easily, prolonged serviceable life.
Owing to adopted technique scheme, the utlity model has:
1, adopt the single layer structure mode, simple in structure;
2, use and safeguard simple;
3, cost is low, is suitable for the little engineering of project investment and uses.
4, sampling, good cooling results, the long service life of self.
Description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1. probe is managed; 2. filter the blowback unit; 3. air intake opening; 4. gas outlet; 5. cooling collar; 6. cooling chamber; 7. sample tap; 8. be blown into mouth in; 9. be blown into mouth outward; 10. vortex cooler.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Referring to accompanying drawing 1, the utility model includes probe pipe 1 and is arranged on the filtration blowback unit 2 of probe pipe 1 end, be provided with the cooling collar 5 of bringing gas port 3 and gas outlet 4 between probe pipe 1 and the filtration blowback unit 2, cooling collar 5 surrounds a cooling chamber 6 with the outer wall of probe pipe 1, and described air intake opening 3 and gas outlet 4 are connected with cooling chamber 6.
Described probe pipe 1 can be on the basis of high-temperature alloy, adopt hot-spraying technique composite heatproof anti-corrosion structure layer to constitute again, have high temperature resistant, anti-washing away and performance such as resistance to oxidation corrosion, thereby guaranteed probe sampling operation stable under rugged surroundings.
Below in conjunction with accompanying drawing 1, further specify principle of work of the present utility model: the high-temperature gas in the stove enters from the sample tap 7 of stopple coupon 1, flow through and filter the blowback unit, filter out as required＞dust of 0.3um after, externally be transferred to analyser under the effect of aspiration pump.Pressurized air enters and filters blowback unit 2 from interior purging inlet 8 and the outer inlet 9 that purges respectively, carries out the inside and outside purging filtrator of program control pulse, and the long-term use of guarantee filtrator is not stopped up.Cold compression air after vortex cooler 10 refrigeration enters cooling chamber 6 from air intake opening 3, by gas outlet 4 natural emptyings, in this process, the cold gas cooling chamber 6 of flowing through endlessly cools off the sample gas in stopple coupon 1 and the stopple coupon 1, and the heat that the cold gas of the cooling chamber 6 of flowing through forms is to a certain extent isolated, furnace high-temperature is greatly reduced to the heat transmission of filtering blowback unit 2, ensured and filtered the stable and reliability that blowback unit 2 filters the blowback effect, maintained easily, prolonged serviceable life.
