Abstract
The utility model provides a fan -type air current moves and shows appearance, contains: transparent nozzle stub, install the both ends at transparent nozzle stub for be connected to transparent nozzle stub flange in the tuber pipe pipeline and install inside transparent nozzle stub, be used for indicateing the fan assembly spare of gas flow state and wind direction. The utility model discloses the way is simple, and low cost can overcome prior art's defect, solve effectively that gas collection handles or ventilation system in the end breathe in or the not enough problem of carminative equilibrium, the degree of difficulty of simplified system debugging and operation maintenance greatly reduces the quantity of blast gate and flowmeter, sparingly pipe -line system's cost.
Description
Technical field
This utility model relates to collection and confinement of gases and processes and aeration technology field, particularly relates to a kind of 24 hours visual fan-type flow of air and shows instrument.
Background technology
Along with development and the progress of science and technology of society, increasingly paying attention to the balance of air quantity in foul gas collection process and Design of Ventilation System, the quality of air balance is directly connected to collection treatment effeciency and the uniformity of ventilating system of foul gas.
And in Practical Project, owing to being affected sealing such as gas skirt, airduct size, scenery resource quality, changeable, the installing space of operating condition, finishing requirement etc. by factors, during circuit design, often it is difficult to the resistance balance between each arm.To this end, generally to arrange air-valve on each branched pipe to regulate air quantity, by changing the drag losses of pipeline, make to realize resistance balance between each branched pipe of system, reach to design requirement.But air-valve regulation is easier to for single or number bye-pass system, but complicated for pipeline, air-breathing or the various system of Exhaust branch pipeline, the such as air supplying and exhausting system of large-scale wastewater treatment plant deodorization collection system, heavy construction or the underground space.If realizing the manage-style amount equilibrium of each end branch, best each end branch pipe is installed air-valve and arranges gas flowmeter, and the cost of pipe-line system will certainly be significantly increased；Even if installing substantial amounts of air-valve and effusion meter, in actual motion, the drag characteristic of each branched pipe can change with the change of the most a certain branch resistance characteristic, air-valve will have to repeatedly adjust, needing substantial amounts of personnel's observed volume and complete EQUILIBRIUM CALCULATION FOR PROCESS, the difficulty of system debug and later stage operation maintenance is the biggest.
On the other hand, for the collection and confinement of gases processing system of uninterrupted operation in 24 hours, especially night due to the change of operating condition, such as brown-outs or instrument is damaged, and the phenomenon causing system pipeline air quantity unbalance also is difficult to be found by people.
Utility model content
This utility model provides a kind of fan-type flow of air to show instrument, way is simple, with low cost, the defect of prior art can be overcome, effectively solve collection and confinement of gases to process or end air-breathing or the balance deficiency problem of aerofluxus in ventilating system, it is greatly simplified the difficulty of system debug and operation maintenance, reduces air-valve and the quantity of effusion meter, save the cost of pipe-line system.
In order to achieve the above object, this utility model provides a kind of fan-type flow of air to show instrument, comprises:
Transparent short tube；
Flange, it is arranged on the two ends of transparent short tube, for being connected in airduct pipeline by transparent short tube；
Fan component, it is arranged on inside transparent short tube, is used for indicating flowing gas state and wind direction.
Described fan component uses vane type small fan.
Described fan component surface-coated fluorescent material.
Described transparent short tube uses transparent material to make.
Described transparent short tube uses corrosion resistant transparent material to make.
Arranging projecting apertures on described transparent short tube, this projecting apertures is arranged on around the junction of fan component and transparent short tube.
This utility model has the advantage that
Way is simple, with low cost, the defect of prior art can be overcome, flow of air is installed and shows that the collection and confinement of gases of instrument processes or ventilating system, it is possible to be greatly simplified the difficulty of system debug and operation maintenance, effectively solve end air-breathing or the balance deficiency problem of aerofluxus, reduce air-valve and the quantity of effusion meter, save the cost of pipe-line system, it is possible to facilitate operational management at the night personnel maintenance to system, it is ensured that uninterrupted operations in 24 hours of system.
Accompanying drawing explanation
Fig. 1 is the structural representation that a kind of fan-type flow of air that this utility model provides shows instrument.
Fig. 2 be in Fig. 1 the A of fan component to schematic diagram.
Detailed description of the invention
Preferred embodiment of the present utility model is illustrated below according to Fig. 1 and Fig. 2.
As it is shown in figure 1, this utility model provides a kind of fan-type flow of air to show instrument, comprise:
Transparent short tube 1；
Flange 2, it is arranged on the two ends of transparent short tube 1, for being connected in airduct pipeline by transparent short tube 1；
Fan component 3, it is internal that it is arranged on transparent short tube 1, is used for indicating flowing gas state and wind direction.
Described transparent short tube 1 uses transparent material to make, such as: lucite；When the fan-type flow of air that this utility model provides shows instrument for foul smell collection processing system implementing, described transparent short tube 1 uses corrosion resistant transparent material to make.
As in figure 2 it is shown, described fan component 3 uses vane type small fan, when the gas in airduct shows instrument from A to the chip flow of air provided by this utility model, vane type small fan rotates, and shows wind direction according to the rotation direction of fan, completes instruction function.
Described fan component 3 surface-coated fluorescent material, facilitates operational management personnel's night inspection.
Can arrange projecting apertures 4 on described transparent short tube 1, this projecting apertures 4 is arranged on around the junction of fan component 3 and transparent short tube 1, is used for keeping in repair dismounting fan component 3.
This utility model way is simple, with low cost, the defect of prior art can be overcome, flow of air is installed and shows that the collection and confinement of gases of instrument processes or ventilating system, it is possible to be greatly simplified the difficulty of system debug and operation maintenance, effectively solve end air-breathing or the balance deficiency problem of aerofluxus, reduce air-valve and the quantity of effusion meter, save the cost of pipe-line system, it is possible to facilitate operational management at the night personnel maintenance to system, it is ensured that uninterrupted operations in 24 hours of system.
Although content of the present utility model has been made to be discussed in detail by above preferred embodiment, but it should be appreciated that the description above is not considered as restriction of the present utility model.After those skilled in the art have read foregoing, multiple amendment of the present utility model and replacement all be will be apparent from.Therefore, protection domain of the present utility model should be limited to the appended claims.
