Abstract
The utility model provides a node removes flue gas device, including annular shell 1, annular porous inner panel 2, supporting blast pipe 3, connection piece 4, concrete structure as follows: annular shell 1 comprises half shell of upper and lower two parts, and half upper and lower shell is assembled through connection piece 4, and annular shell is equipped with supporting blast pipe 3.1 inside being equipped with rather than the annular porous inner panel 2 that the shape is the same on the annular shell, the two forms the exhaust cavity. The utility model discloses can strengthen the negative pressure, closely catch the flue gas, improve exhaust efficiency.
Description
Technical field
The utility model relates to a kind of node except flue gas device, belongs to gas discharging technical field, particularly fume emission aspect.
Background technology
In existing smoke emission device, the most general with enclosure application, it is widely used in the discharge of chemical laboratory waste gas, combustion gas furnace waste gas, kitchen oil flue gas etc., and waste gas is discharged by the exhaust smoke outlet being located at cover body center.But distant due to enclosure and flue gas source, does not carry out smoke abatement operation in aerogenesis source (going out the node location of flue gas), produces negative pressure less, make it flue dust can not be trapped discharge completely, flue gas easily spreads towards periphery, causes environmental pollution, and exhaust efficiency is lower.In order to increase exhaust efficiency, known method strengthens power of fan to strengthen negative pressure, but the method energy consumption is higher and noise pollution is serious.Bell-type smoke evacuation simultaneously occupies larger volume, and propose restriction to installing space, therefore, improvement needed badly by this kind of fume extractor.
Summary of the invention
In order to overcome the deficiency of background technology, the utility model provides a kind of node except flue gas device.
The technical scheme that the utility model adopts is: the utility model provides a kind of node except flue gas device, forms stronger negative pressure, closely catch flue gas at aerogenesis source node, improves exhaust efficiency.The utility model mainly comprises annular outer cover, annular porous inner panel, brace, supporting blast pipe.
The annular outer cover shape side of being annular or annular.Be divided into upper half shell and lower half shell two parts, utilize brace to be assembled by upper and lower half shell.Annular outer cover is provided with supporting blast pipe, and blast pipe installation form can be side, offside, three sides or four sides, can carry out design and installation according to actual conditions.Supporting blast pipe connects corresponding pipeline and is exhausted operation.
Annular porous inner panel shape is consistent with annular outer cover form trait, is also divided into upper and lower two parts, and inner annular plate and annular outer cover are in conjunction with formation cavity body, and flue gas thus cavity body enters exhaust passage.Inner annular plate is loose structure, and this structure can make gas flowing accelerate, and improves smoke discharging effect, and hole shape is circular, and the diameter of circular port is greater than 1mm.The utility model mounting arrangements form can be vertical or horizontal.

Detailed description of the invention
For better the utility model being described, below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described further: as Fig. 1 and Fig. 2, the utility model provides a kind of node except flue gas device, comprise annular outer cover 1, annular porous inner panel 2, supporting exhaust duct 3, brace 4, the concrete structure of the present embodiment is as follows.
The annular outer cover 1 shape side of being annular.Side's ring shell is divided into upper half shell and lower half shell, and centre connects with brace 4.Annular outer cover 1 is provided with supporting exhaust duct 3, and supporting exhaust duct 3 form is offside.
Annular porous inner panel 2 is identical with annular outer cover 1 form trait, and annular porous inner panel 2 is welded on annular outer cover 1, forms exhaust cavity.Annular porous inner panel 2 structure is as Fig. 3, and be many circular pore structure, Circularhole diameter is greater than 1mm.
Device gas circuit and flue gas enter, discharge currents is to seeing Fig. 4 and Fig. 5 respectively, after flue gas is by air intake access to plant, owing to being negative pressure in device, gas enters cavity by annular porous inner panel 2, then carries out air inducing discharge respectively through upper and lower two supporting exhaust ducts 3 of annular outer cover 1 in the cavities.The utility model is directly exhausted operation at flue gas source node, and negative pressure is comparatively large, exhaust efficiency is high, structure is simple, the easy for installation and small volume that takes up room.
It should be noted that, more than describing is only for the exemplary of the present embodiment and indicative explaination, not limits protection domain of the present utility model.Under the prerequisite not departing from the utility model design, all various improvement of making the technical solution of the utility model and distortion, all should fall into the protection domain that claims of the present utility model are determined.
