Description
Technical field
The utility model relates to flue gas monitoring field, and specifically a kind of flue detects sample tap flange.
Background technology
The Main Function of chimney is the cigarette that puts a chimney on the stove and make the fire draw, and drains flue gas, improves burning condition.Flue is the passage of chimney, is interior duct flame and cigarette delivered to space outerpace and go of chimney, is the pipeline for the flue gas or foul smell getting rid of burning activity generation.Measure the flow of flue gas, the content of dust concentration and flue gas gaseous state and solid-state composition is observed, analyzed its change and the process to ambient influnence, is one of main monitoring project of industrial enterprise's Pollution Source Monitoring.The object of flue gas monitoring is: (1) checks whether the concentration of emission of various pollutant in flue gas and discharge capacity meet the discharge standard of national regulation; (2) performance and the service condition of smoke eliminator and pollution prevention measure is checked; (3) for atmospheric environment management and atmosphere quality evaluation provide foundation.Monitoring project mainly contains: Gas Parameters measures; Flue gas flow measures; Smoke components is monitored; Dust concentration, domain size distribution and component monitoring in flue gas; Lingemann blackness monitoring etc.
The method of sampling to flue gas at present on walling of flue, selects suitable position, perforate, and hole is welded and fixed a flange, and probe tube is inserted by flue, draws flue gas by Flange joint sampling probe, and probe has filter core, is used for filtering the flue dust in flue gas.Because the flange section of sampling probe and flue junction does not have attemperator, after sample gas extracts from flue, when probe filter core, temperature declines, steam in flue gas is easily separated out, and sample gas not yet filters herein, the ash of water in sample gas is combined and forms corrosive substance, Yi Yuejie is larger, thus blocks probe tube and corrosion flange and sampling probe.
Existing settling mode is at sampling probe and adpting flange place dress electric heater, be incubated, filter core is kept dry, although this mode can solve appeal problem, but because electric equipment introduced by needs, and gathering hole is natively smaller, the trouble of operation will certainly be increased, and waste energy.
Utility model content
The utility model is intended to provide a kind of can insulation sampling filter core when not consuming additional energy source to detect sample tap flange at flue.
Flue detects sample tap flange, comprise a connecting pipe of pipeline, one end of described connecting pipe of pipeline embeds walling of flue, and the other end is provided with ring flange and the vexed plate of flange, described ring flange and the vexed plate of flange are bolted fixing, are provided with sealing gasket between ring flange and the vexed plate of flange; Described connecting pipe comprises the double-skin duct structure of outer tube and interior pipe composition; Cavity is left between described outer tube wall and inner tubal wall; The port that described interior pipe embeds flue is provided with smoke deflector.
Utility model works principle:
Flue gas in flue is always toward rising, under the guiding of smoke deflector, can enter in the cavity of double-skin duct structure of connecting pipe, because flue gas itself has very high temperature, just nature can give interior pipe and the ring flange heating of connecting pipe, now, the sampling probe be in flange is just natural in heating and thermal insulation, thus keep the drying of probe inner filter core, after sample gas extracts from flue, when probe filter core, temperature would not decline, steam in flue gas is not easily separated out, thus the ash of water in sample gas of separating out in mode sample gas is combined and forms corrosive substance, thus prevent blocking probe tube and corrosion flange and sampling probe.
The utility model mainly utilizes the heat of flue gas in flue self, it is utilized to be flange heating and thermal insulation, thus ensure the drying of probe tube inner filter core, therefore flue of the present utility model detects sample tap flange compared with prior art, can economize energy, blocking probe tube can be prevented again and corrosion flange and sampling probe.
Further, described outer tube is horn-like structure, and one end that its opening is larger embeds flue.
Outer tube is trumpet-shaped be designed be beneficial to high-temperature flue gas below pipeline enter cavity, and the discharge of the lower flue gas of temperature after pipeline being heated above pipeline, be conducive to the balance keeping flue gas turnover.
Further, the angle between described smoke deflector and walling of flue is 60 degree.
Find that this angle is conducive to the importing of flue gas most through practice.
Further, described outer tube outer wall is provided with heat-insulation layer.
Heat-insulation layer be designed with the maintenance being beneficial to flange temperature.
Accompanying drawing explanation
Fig. 1 is embodiment 1 structural representation that flue of the present utility model detects sample tap flange;
Fig. 2 is embodiment 2 structural representation that flue of the present utility model detects sample tap flange.
