Abstract
The utility model provides a filtered heating device and a filtering device for a dilution probe of an online flue gas monitoring system. The filtered heating device comprises a heating sleeve, and is characterized in that the front end of the heating sleeve is provided with a circular pipe; and the inner wall of the circular pipe is provided with a plurality of baffles which are arranged in a mutual intersection manner. The filtering device removes serous fluid by a buffering area formed by the baffles which are mutually intersected so as to reduce the humidity, so that dried flue gas enters a dilution probe filter which can work normally.
Description
Technical field
The utility model relates to the environmental protection equipment technical field, particularly a kind of filtering and heating device and filtration unit of smoke on-line monitoring system dilution probe.
Background technology
In the process of flue gas monitoring systematic survey, in the sulphuric dioxide measuring point flue of living in, measurement environment is poor, smoke moisture is big, this system comprises the heating and filtering device, as shown in Figure 1, this heating and filtering device is provided with cable inlet 106, this heating and filtering device comprises: be positioned at external heated sleeve pipe 104, be wound with heater strip 105 on the inwall of described heating muff 104, the center of described heating muff is the flue gas dilution probe, and the front end of described dilution probe is a dilution probe filtrator 103, during owing to work, the temperature of filtering and heating device is higher than flue-gas temperature far away, and (flue-gas temperature is 45 ℃, the temperature of heating muff 104 is about 220 ℃), flue dust in the flue gas and slurries are highly susceptible to the inside surface attached to described heating muff 104, and fouling is solidified.Because this dilution probe filtrator 103 has directly touched clean flue gas, and temperature is lower than other position temperature herein, its surface has also just formed the slurries plugged zone of thickness, flue gas can not be passed through from this dilution probe filtrator 103, the corrosivity of the slurries that this kind is thick is considerably beyond original clean flue gas, the corrosivity that probe and the miscellaneous part of this heating and filtering device are caused is quite serious, and this rear end that is used for the flue gas sampling dilution probe filtrator 103 of flue gas sampling is the velocity of sound aperture of dilution usefulness, the effect of this velocity of sound aperture is this flue gas to be carried out 1: 100 times dilution, there is negative pressure these heating muff velocity of sound aperture 104 inside, time one is long, the thick slurry that dilution probe filtrator 103 front ends adhere to will some be passed through quartzy screen pack of this velocity of sound aperture, enter this velocity of sound aperture, stop up this velocity of sound aperture, the measurement mechanism that causes the back is popped one's head in as flue gas dilution, measuring object thieff hatch 107 cisco unity malfunctions such as grade.
The utility model content
The utility model provides a kind of can remove slurries, reduce humidity, makes the filtration unit of the smoke on-line monitoring system dilution probe that flue gas dilution probe can operate as normal.
To achieve these goals, the utility model provides following technical scheme: a kind of filtering and heating device of smoke on-line monitoring system dilution probe is characterized in that described filtering and heating device comprises: add
Thermal sleeve, wherein, the front end of described heating muff is equiped with pipe, and described round tube inner wall is provided with a plurality of baffle plates, the mutual cross arrangement of described a plurality of baffle plates.
Preferably, described baffle plate is a semilune, and a described baffle plate inserts between two the adjacent baffle plates in opposite.
Preferably, described pipe is connected with the mode of described heating muff by single jackscrew.
Preferably, the tube wall of described pipe front end is provided with leak.
The utility model also provides a kind of filtration unit, and it comprises: pipe, described round tube inner wall is provided with a plurality of baffle plates, the mutual cross arrangement of described a plurality of baffle plates.
Preferably, described baffle plate is a semilune, and a described baffle plate inserts between two the adjacent baffle plates in opposite.
By implementing above technical scheme, have following technique effect: the utility model provides the filtering and heating device, the buffer zone that constitutes by cross one another baffle plate removes slurries, reduces humidity, makes dry flue gas enter the dilution probe filtrator, and flue gas dilution is popped one's head in can operate as normal.
Description of drawings
