Abstract
The utility model relates to a sampling device for a direct drawing type CEMS system, which is connected on a process pipeline of a system and is characterized by mainly including a sampling probe, a filter, a heater and a sampling pipe which are serially connected in order; and a heat-insulation material is coated on the outer wall of the sampling pipe. The design of the device in sampling, filtering, high-temperature heating and heat-insulation transporting meets the requirement of the sample gas for the collecting temperature, ensures the sample gas not to be dewed and the components not to be changed in the transporting process; and it is only necessary to coat the heat-insulation material on the outer wall of the sampling pipe without coating an electric heat tape so that the pipeline is light, not easy to be damaged and easy for maintenance and repair.
Description
Technical field
The utility model relates to a kind of direct extraction-type CEMS systematic sampling device that is used for, and is specially adapted in the direct extraction-type CEMS system of power plant the collection to sample gas.
Background technology
Fume emission continuous monitoring (CEMS) system is a kind of device that solid pollutant granule density, gaseous contamination substrate concentration and gross contamination emission is carried out automatic monitor for continuously.It is sent to environmental protection competent authorities with Monitoring Data and information, is up to state standards with the density and gross volume of such pollutants to be discharged of guaranteeing blowdown enterprise pollution thing.The CEMS system also can monitor and manage the various relevant environmental protection equipment (as desulfurization, denitrification apparatus etc.) in the factory in addition, thereby impels it to improve the efficient of environmental protection facility.
Directly extracting sampling method is a kind of method of sampling commonly used in the CEMS system.Directly extracting sampling method is directly to extract the method that the sample gas in the flue is analyzed, and mainly is divided into three types: hot wet method, pre-treatment mode and post processing mode.All comprise the hot sampling pipe of sampling probe, filtrator and companion in the sampling system of hot wet method and post processing mode.Its principle is: coarse filter is housed to remove particle on probe; For gas soluble in water, must heat, must carefully keep the sample gas temperature the process that is sent to analyser from probe that is extracted and be higher than dew point.If in this process, heating system breaks down, then can make portion gas dewfall and lose part SO in transmission pipeline
2, NO
xThereby, cause test result inaccurate.In addition, the sour gas that remains in the transmission pipeline may cause that the burn into of system unit results in blockage, even analyser is broken down and damages, and causes the total system collapse.For avoiding above-mentioned defective, the normal hot sampling pipe of companion that adopts in this type systematic, promptly the sampling pipe outer wall must coat the ribbon heater that is used to heat, and to guarantee sample gas from popping one's head in to the course of conveying of analytic system, temperature is higher than dew point all the time.Yet the hot sampling pipe of companion for long still some problems can occur in actual applications: coat the ribbon heater outward as sampling pipe, can make the quality of pipeline increase, and price is higher; And keep whole sampling pipe temperature evenly also relatively difficult; During heating sampling pipe easily crooked, cave in, recess may cause sample air cooling with fixed attention; Damaging appears in long transmission line heating, ribbon heater easily; Heating wire can only be changed pipeline again in case the appearance fracture not only is difficult to discovery, and can not repairs, and involves great expense etc.
The utility model aims to provide a kind of direct extraction-type CEMS systematic sampling device that is used for, sampling, filtration that this device adopts, high temperature heating, insulation transfer designs, can satisfy of the requirement of sample gas to collecting temperature, guarantee that dewfall, composition do not change sample gas in course of conveying, can make sampling pipe outer need not coat the ribbon heater again, only need to coat insulation material, this make pipeline relatively merrily and lightheartedly, not fragile and be easier to safeguard and maintenance.
The utility model content
The utility model purpose is to provide a kind of direct extraction-type CEMS systematic sampling device that is used for, this device both can have been guaranteed sample gas dewfall not in course of conveying, can make sampling pipe outer need not coat the ribbon heater again, only need to coat insulation material, this make pipeline relatively merrily and lightheartedly, not fragile and be easier to safeguard and maintenance.
For achieving the above object, the utility model adopts following technical scheme:
A kind ofly be used for direct extraction-type CEMS systematic sampling device, be connected on the process pipe of system, it is characterized in that mainly be in series successively by sampling probe, filtrator, well heater and sampling pipe, described sampling pipe outer wall coats insulation material.
Above-mentioned sampler can also be provided with back-blowing device on the pipeline between filtrator and the well heater, described back-blowing device comprises valve and blowback source of the gas; Described valve one end is connected with pipeline between filtrator and the well heater, and the other end links to each other with the blowback source of the gas.
The beneficial effects of the utility model:
Sampling, filtration that this device adopts, high temperature heating, insulation transfer designs, can satisfy of the requirement of sample gas to collecting temperature, guarantee that dewfall, composition do not change sample gas in course of conveying, can make sampling pipe outer need not coat the ribbon heater again, only need to coat insulation material, this make pipeline relatively merrily and lightheartedly, not fragile and be easier to safeguard and maintenance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further details, but protection domain of the present utility model is not limited thereto.
As shown in Figure 1, a kind of direct extraction-type CEMS systematic sampling device (this device is connected the process pipe of CEMS system) that is used for, mainly be in series successively by sampling probe 1, filtrator 3, well heater 6 and sampling pipe 7, described sampling pipe 7 outer walls coat insulation material 2.On the pipeline between filtrator 3 and the well heater 6 back-blowing device is set, described back-blowing device comprises valve 4 and blowback source of the gas 5; Described valve 4 one ends are connected with pipeline between filtrator 3 and the well heater 6, and the other end links to each other with blowback source of the gas 5.
During sampling, valve-off 4, sample gas enters through sampling probe 1, and with solid particle filterings such as flue dust, heater via 6 is heated to 180～200 ℃ with flue-gas temperature then through filter 3, is transported in the CEMS rack through the sampling pipe 7 that is coated with insulation material 2 at last.Flue gas is heated to sufficiently high temperature when passing through well heater 6 in pipeline, be higher than dew point to guarantee it all the time through temperature in the process of sampling pipe 7, thereby can prevent effectively that sample gas dewfall in course of conveying from causing corrosive pipeline and composition to change.
When stopping to sample, Open valve 4, the blowback scavenging body in the blowback source of the gas 5 enters from conveyance conduit 8, purges the dust that adheres on the filtrator 3, and it is purged to flue, thereby prevents that filtrator is blocked.
Claims (2)
