Abstract
A kind of tail gas transportation system, including blower (1), air hose (2), Venturi tube (3), butterfly valve (4), air inlet pipe (5), the import of blower (1) is connected with the tail gas outlet of polyester device by flange, and outlet is connected with the import of air hose (2) by flange；The outlet of air hose is connected with the entrance end of Venturi tube (3) by flange, the entrance side of Venturi tube (3) is equipped with air inlet pipe (5), butterfly valve (4) are installed with by flange in air inlet pipe (5), which is half-open position.When the tail gas air quantity and concentration that flow through Venturi tube increase suddenly, this system can be acted on by the self-priming of Venturi tube, increased the air imbibed quantity of air inlet pipe, be diluted to tail gas, play the role of reducing concentration.
Description
Technical field
The utility model belongs to polyester production facility technical field, and in particular to a kind of tail gas transportation system.
Background technique
The organic exhaust gas such as acetaldehyde, ethylene glycol are typically contained in the tail gas of production of polyester discharge, factory is directed to the tail gas at present
Typically directly burning disposal.However, polyester tail gas will appear intermittent wind during being produced using interval polyester device
The case where amount and concentration are uprushed, causes exhaust combustion insufficient, in turn results in air pollution.Therefore, be passed through in due course air to
Tail gas concentration is diluted into key to solve this problem.
Summary of the invention
The purpose of this utility model is to provide a kind of tail gas transportation systems, in the feelings that tail gas air quantity and concentration increase suddenly
Under condition, is acted on by the self-priming of Venturi tube, draw air into tail gas pipeline and tail gas is diluted, guarantee the abundant of tail gas
Burning.
The purpose of this utility model adopts the following technical solutions to realize.According to the utility model proposes a kind of tail gas
Transportation system, including blower 1, air hose 2, Venturi tube 3, butterfly valve 4, air inlet pipe 5, the import of blower 1 and the tail gas of polyester device
Outlet is connected by flange, and outlet is connected with the import of air hose 2 by flange；The outlet of air hose enters with Venturi tube 3
Mouth section end is connected by flange, and the entrance side of Venturi tube 3 is equipped with air inlet pipe 5, is installed in air inlet pipe 5 by flange
Butterfly valve 4, the butterfly valve 4 are half-open position.
By above-mentioned technical proposal, a kind of tail gas transportation system of the utility model, in the tail gas air quantity for flowing through Venturi tube
It in the case where increasing suddenly with concentration, can be acted on by the self-priming of Venturi tube, increase the air inlet in air inlet pipe, to tail
Gas is diluted, and plays the role of reducing concentration.
The above description is merely an outline of the technical solution of the present invention, in order to better understand the technology of the utility model
Means, and being implemented in accordance with the contents of the specification, and to allow the above and other purpose of the utility model, feature and excellent
Point can be more clearly understood, special below to lift preferred embodiment, and cooperate attached drawing, and detailed description are as follows.

Specific embodiment
Further to illustrate that the utility model is to reach technical means and efficacy used by predetermined purpose, below in conjunction with
Attached drawing and preferred embodiments, to according to the utility model proposes a kind of its specific embodiment of tail gas transportation system, structure, feature
And its effect, detailed description is as follows.
Referring to Fig. 1, a kind of tail gas transportation system, including blower 1, air hose 2, Venturi tube 3, butterfly valve 4, air inlet pipe 5, wind
Machine 1 selects air quantity 3000m3The blower of/h, total pressure 2500Pa；Air hose 2 uses PP material, nominal diameter DN200；Venturi
The entrance internal diameter of pipe 3 is that DN200, contraction section cone angle are about 21 ° ± 2 °, throat inner radius DN70, diffuser cone angle is 8 °~
15 °, its outlet end internal diameter be DN200；The internal diameter of air inlet pipe 5 is DN150.
The exhaust port of the import of the blower 1 and polyester device (figure is not painted) is connected by flange, outlet and
The import of air hose 2 is connected by flange.The outlet of air hose 2 is connected with the entrance of Venturi tube 3 by flange, the Venturi tube
3 entrance side is equipped with air inlet pipe 5, is installed with butterfly valve 4 by flange in air inlet pipe 5, which is half-open position.
When work, the tail gas that blower 1 generates polyester device is extracted out, is delivered to processing after air hose 2 and Venturi tube 3
In device.When tail gas stream is through enturi tube, as pipeline section is gradually reduced, the flow velocity of tail gas becomes larger, and pressure reduces, at this moment
Negative pressure can be formed in the interface of Venturi tube 3 and air inlet pipe 5, the air around air inlet mouth of pipe is caused to be inhaled into Venturi tube,
As tail gas flows into processing unit together.When the tail gas air quantity for flowing through Venturi tube increases suddenly, generated in Venturi tube
Negative pressure also will increase so that the air imbibed quantity in air inlet pipe 5 increases, to play the role of diluting tail gas concentration.
The above descriptions are merely preferred embodiments of the present invention, not does in any form to the utility model
Limitation, any person skilled in the art do not departing within the scope of technical solutions of the utility model, practical new according to this
The technical spirit of type any simple modification, equivalent change and modification made to the above embodiment, still fall within the utility model
In the range of technical solution.
