Description
Technical field
The utility model relates to a kind of drier, specifically relates to a kind of desulfurization sampling drier.
Background technology
China's economy increases fast, and every construction obtains great achievement, but has also paid huge resource and the ruined cost of environment, and the ruined contradiction of economic development and resource environment is sharp-pointed day by day, and problem of environmental pollution is strong day by day.
In order further to strengthen energy-saving and emission-reduction work, also be pressing for of reply Global climate change, " the comprehensive programme of work of energy-saving and emission-reduction " that the State Development and Reform Commission that State Council prints and distributes formulates together with relevant department, clear and definite 2010 China realize the goal task and the general requirement of energy-saving and emission-reduction." scheme " point out, by 2010, SO2 emissions reduced to 2,295 ten thousand tons by 2,549 ten thousand tons in 2005, and COD (COD) reduces to 1,273 ten thousand tons by 1,414 ten thousand tons; The whole nation is established city's treatment rate of domestic sewage and is not less than 70%, and percentage of industrial solid waste that is comprehensively utilized reaches more than 60%.
The flue dust of power plant, smoke pollution are comparatively serious, and therefore country carries out on-line monitoring to flue dust, the smoke pollution of power plant emission, the concentration of harmful components in strict its emission gases of control.Main mode is that the composition to nitrogen, sulphur in the discharged flue gas behind the power plant desulfurization carries out sample detecting.Domestic present employed sulfur method is most of to contain a large amount of moisture content and mud for wet desulphurization in the flue after the desulfurization, be easy to stop up sampling apparatus; Simultaneously domestic power-plant flue gas detects the flue gas of the frequent directly contact of the heating part highly corrosive of sampling probe, and often having moisture content to see through pipeline enters in the molecule instrument, can cause damage to equipment, not only cause very big loss, and can influence the real-time and the accuracy of detection.
Summary of the invention
At the defective of prior art, the purpose of this utility model provides a kind of desulfurization sampling drier that is installed on the sampling probe, to guarantee the normal operation of probe, improves detection accuracy.
For reaching above-mentioned purpose, the utility model has adopted following technical scheme:
A kind of desulfurization sampling drier is made up of pipe, thermocouple, heater protecting sleeve pipe, temperature controller and the long sleeve pipe of installation in heating wire, the heater; Heating wire is wound on the interior pipe of heater, and its rear end is connected with thermocouple and is electrically connected with temperature controller; The pipe front end passes in the heater protecting cover insertion flue in the heater, and the rear end is provided with the internal thread that is used to connect sampling probe or adapter coupling; The heater protecting cover is sheathed on the outside of heating wire, and its rear end is connected with the long bobbin seal of installation; Long sleeve pipe rear end is installed to be fixedly installed on the flue outer wall.
The utility model also can further be realized by the following technical programs:
Described desulfurization sampling drier, wherein, described heater protecting sleeve pipe is fixedlyed connected by flange with the long sleeve pipe of installation, and by being located in the asbestos seal pad sealing between the two.
Described desulfurization sampling drier, wherein, the long sleeve pipe of described installation is installed on the flue outer wall by the flange that the rear end is provided with.
Owing to adopted technique scheme, made the utility model possess following effect:
1, desulfurization sampling drier of the present utility model, its heater protecting cover is isolated fully with heater strip and flue, has avoided Yin Gaowen to cause the corrosion of the interior soda acid gas of flue to firing equipment and circuit, drier long service life;
2, desulfurization sampling drier of the present utility model adopts the heater strip that heats interior pipe and be wrapped in outside managing in the heating that the sample gas in the pipe in flue enters is carried out gradually heat oven dry, can effectively remove the moisture in the flue gas, has improved accuracy of detection;
3, desulfurization flue gas drying device of the present utility model, the use thermocouple reaches the intelligent temperature controller with its adapted, and the temperature constant that sampling section can be entered the mouth reaches the dry requirement to gas in certain temperature range;
4, the pipe rear end is an internal thread in the desulfurization flue gas drying device of the present utility model, heater, can directly be connected with sampling probe or be connected with multiple sampling probe by adapter coupling, and is easy to connect, helps the sampling and the detection of flue gas after desulfurization;
5, the utility model is reasonable in design, and is easy to use, has preferable social economic value, suitable applying.
Description of drawings
Fig. 1 is the sectional structure schematic diagram of the utility model desulfurization sampling drier.
The specific embodiment
1 describe the utility model in detail in detail in conjunction with the accompanying drawings below.Used heater strip, thermocouple and temperature controller are the commercially available prod in the utility model.
A kind of desulfurization sampling drier is by managing 3 in heater protecting sleeve pipe 1, heating wire 2, the hollow heater, thermocouple 4, long sleeve pipe 6 being installed and temperature controller (embodiment among the figure) is formed; Heating wire 2 is wound in the heater and manages on 3, and its rear end is connected with thermocouple 4 and is electrically connected with temperature controller; Pipe 3 front ends pass in the heater protecting cover 1 insertion flue in the heater, and the rear end is provided with the internal thread that is used to connect sampling probe or adapter coupling; Heater protecting cover 1 is sheathed on the outside of heating wire 2, and its rear end is tightly connected with the long sleeve pipe 6 of installation; Long sleeve pipe 6 rear ends are installed to be fixedly installed on the flue outer wall.
For realizing sealing, heater protecting sleeve pipe 1 can be fixedlyed connected by flange with the long sleeve pipe 6 of installation, and by being located in asbestos seal pad 7 sealings between the two.Simultaneously, long sleeve pipe 6 being installed also can be installed on the flue outer wall by the flange that the rear end is provided with.
During concrete the use, the flue gas drying device that will come off is installed in the flue, and the front end of pipe 3 gos deep in the flue in the heater, and sampling probe is screwed onto the rear end of pipe 3 in the heater.Connect temperature controller, open heater, heating wire begins heating.Dry and the sampling flue gas quilt in the interior pipe 3 of the heater that enters hollow in the flue is gradually warm, walk to sampling probe place bone dry, so accuracy of detection is higher.
