One end of a smoke extraction pipe is a straight pipe section, and the other end thereof is a flaring section; a smoke cooling sleeve is coaxially installed at the outside of the straight pipe of the smoke extraction pipe; the interior of the smoke cooling sleeve is divided into an inner layer and an outer layer; a spiral fin is arranged between the outer layer and the inner layer; one end of the smoke cooling sleeve close to the flaring section of the smoke extraction pipe is provided with a cooling water inlet and a cooling water outlet; the cooling water inlet is communicated with the inner layer of the smoke cooling sleeve; the cooling water outlet is communicated with the outer layer of the smoke cooling sleeve; the flaring section of the smoke extraction pipe is connected with a sleeve chuck of a filter cartridge by thread; the sleeve chuck of the filter cartridge is internally provided with the filter cartridge; and a temperature measuring element is arranged on the straight pipe of the smoke extraction pipe which is not arranged on the smoke cooling sleeve. The smoke sampling device can effectively reduce the temperature of extracted high temperature smoke, also ensure the temperature to be not less than that of acid dew point, monitor the temperature of cooled smoke, and complete sampling of smoke and fly ash.
Description
Technical field
The utility model relates to the flue gas sampling device, especially relates to a kind of flue gas sampling device that can carry out flying ash sampling simultaneously.
Background technology
When flue gas is analyzed, generally need gather flue gas, carry out dust removal by filtration then, dehydration is delivered to accurate gas analyzer and is carried out analytical test after the moisture absorption.Be to guarantee the accuracy of analysis result, fully analyze each ingredient components in the flue gas under the prerequisite that should as far as possible avoid loss in the transmission course and gas to sneak in principle.Existing flue gas is gathered and is stored with air bag after rifle is gathered gas in the mode of bleeding usually, the gas that stores in the air bag is for further processing again, owing to do not handle through dust arrester before collection, can't sample to flying dust in the flue gas.It is simple in addition the high-temperature flue gas that collects to be carried out the equipment of cooling processing, and can't effectively reduce flue-gas temperature and collecting temperature is monitored, damage equipment when causing temperature too high (as burning out air bag), temperature is crossed and is formed acid when low and reveal etching apparatus.
Summary of the invention
At having problems in the above background technology, the purpose of this utility model is to provide a kind of flue gas sampling device that can carry out flying ash sampling simultaneously, can carry out dedusting simultaneously, flying ash sampling, and the device that the temperature of collection flue gas is monitored.
The technical solution adopted in the utility model is:
The utility model comprises fume extraction pipeline, flue gas cooling cover, temperature element, filter cylinder jacket casing and filter cylinder; One end of fume extraction pipeline is a straight length, its other end is a flared section, the flue gas cooling cover is coaxially installed on outside the straight tube of fume extraction pipeline, flue gas cooling cover inside is divided into inside and outside two-layer, outer and interior interlayer is provided with spiral fin, be provided with cooling water intake and chilled water freeing port at a end near the flue gas cooling cover of fume extraction pipeline flared section, cooling water intake is communicated with the internal layer of flue gas cooling cover, the chilled water freeing port is communicated with the skin of flue gas cooling cover, fume extraction pipeline flared section is threaded with the filter cylinder jacket casing, filter cylinder is installed in the filter cylinder jacket casing, temperature element is installed not being installed on the fume extraction pipeline straight tube of flue gas cooling cover.
The beneficial effect that the utlity model has is:
The utility model can effectively reduce the temperature of the high-temperature flue gas that is extracted, and can guarantee that again flue-gas temperature is not less than acid dew-point temperature, can monitor the cooled smoke temperature, and finish dedusting and Fly ash sampling to flue gas.
Description of drawings
Fig. 1 is a structural principle synoptic diagram of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Among the figure: 1. fume extraction pipeline, 2. flue gas cooling cover, 3. spiral fin, 4. cooling water intake, 5. chilled water freeing port, 6. temperature element, 7. filter cylinder jacket casing, 8. filter cylinder.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1 and Figure 2, the utility model comprises fume extraction pipeline 1, flue gas cooling cover 2, temperature element 6, filter cylinder jacket casing 7 and filter cylinder 8; One end of fume extraction pipeline 1 is a straight length, its other end is a flared section, flue gas cooling cover 2 is coaxially installed on outside the straight tube of fume extraction pipeline 1, flue gas cooling cover 2 inside are divided into inside and outside two-layer, outer and interior interlayer is provided with spiral fin 3, be provided with cooling water intake 4 and chilled water freeing port 5 at a end near the flue gas cooling cover 2 of fume extraction pipeline flared section, cooling water intake 4 is communicated with the internal layer of flue gas cooling cover 2, chilled water freeing port 5 is communicated with the skin of flue gas cooling cover 2, fume extraction pipeline flared section is threaded with filter cylinder jacket casing 7, filter cylinder 8 is installed in the filter cylinder jacket casing 7, be not installed in installation temperature element 6 on fume extraction pipeline 1 straight tube of flue gas cooling cover 2.
Described temperature element 6 is thermopair, thermal resistance thermo detector or infrared thermometer.
Principle of work of the present utility model is as follows:
During the work of this smoke sampling rifle, chilled water is by cooling water intake 4 inputs, chilled water directly contacts with fume extraction pipeline 1 outer wall and carries out heat exchange, the chilled water that has carried out heat exchange subsequently enters skin by the front side hole, flow along spiral fin 3 directions,, strengthen heat radiation down through the chilled water disturbance of helical layer fin 3 outside of heat exchange at last by 5 outputs of chilled water freeing port, to avoid influencing cooling effect to high-temperature flue gas owing to heat exchange makes the cooling water temperature of input internal layer too high.The cooling cover outlet is provided with a temperature element 6, so that the temperature of cooling off the back flue gas is monitored, can come exit gas temperature is regulated and control by regulating the chilled water input quantity, is more or less than acid dew-point temperature to guarantee that exit gas temperature can not crossed.Enter in the filter cylinder jacket casing 7 through cooled smoke, then through being embedded in the filter cylinder 8 back pass-outs in the filter cylinder jacket casing 7, under institute's flying dust of being with is kept off through filter cylinder the time in the flue gas and rest on the filter cylinder inwall.Carry out fly ash content when analyzing, only need to screw out a part behind the filter cylinder jacket casing, carefully take out filter cylinder, get quantitative flying dust from the filter cylinder inwall and measure and get final product.
