Abstract
The invention discloses an exhaust treatment device for a photovoltaic sintering furnace. The exhaust treatment device comprises an organic exhaust pipeline, an organic exhaust fan and an organic tower, wherein an air inlet of the organic exhaust pipeline is positioned above an air outlet of the sintering furnace in a separate manner; the organic exhaust pipeline is provided with a U-shaped bent pipe part; a cooling water tank is arranged outside the U-shaped bent pipe part; a drain outlet is formed in the bottom of the U-shaped bent pipe part. The improved exhaust treatment device for the photovoltaic sintering furnace solves the problem that exhausted organic matters deposit and flow backwards in the organic exhaust pipeline.
Description
Technical field
The present invention relates to sintering furnace technical field of waste gas treatment, especially relate to a kind of photovoltaic sintering furnace exhaust gas processing device.
Background technology
The manufacture craft of solar battery sheet comprises the high temperature sintering to cell piece, and its capital equipment is exactly sintering furnace.In sintering process, sintering furnace can produce organic exhaust gas, must discharge in time, generally be called in the industry organic row.The organic matter that sintering furnace produces in oven dry sheet subprocess is discharged the pipeline that workshop sucks organic tower by organic row.General organic row is made up of stainless steel pipes, organic exhaust blower, organic tower.General organic discharge pipe is not owing to having pollutant-removing system, and long-time production can produce organic deposition at organic discharge pipe inwall, and if things go on like this can exhaust air rate be caused to reduce by blocking pipe, organic matter effectively can not discharge workshop.Even organic matter can pass back in sintering furnace, pollutes the product in sintering process.
As Chinese Patent Application No.: in the patent document of 200820169373.1, disclose a kind of sintering furnace air-exhausting structure, comprise the shaft of sintering furnace, exhaust column, exhaust column outlet, shaft is provided with the escape pipe of sintering furnace, directly over escape pipe, be provided with exhaust column, escape pipe and exhaust column are the structure of separating.Such structure can better be avoided being taken away by a sintering furnace chamber inside point heat because pipeline is directly connected when the wind-force of exhausting is bigger than normal and causing the labile state of inner thermal field, thus reaches the stability increased in sintering furnace cavity, raising product sintering quality qualification rate.But there is the problem that organic matter deposits backflow in exhaust column.
Summary of the invention
The present invention is the problem in order to solve organic deposition backflow in the organic discharge pipe of sintering furnace, provides a kind of photovoltaic sintering furnace exhaust gas processing device of improvement.
To achieve these goals, the present invention is by the following technical solutions:
A kind of photovoltaic sintering furnace exhaust gas processing device of the present invention, comprise organic discharge pipe, organic exhaust blower and organic tower, be separated setting above the gas outlet that the air inlet of described organic discharge pipe is positioned at sintering furnace, described organic discharge pipe is provided with U-bend portion, be provided with cooling water tank outside described U-bend portion, U-bend is provided with sewage draining exit bottom portion.
The present invention will transform the organic row of tradition, organic discharge pipe devise a U-bend portion, then U-bend portion be put into cooling water tank, organic steam condensation is deposited in bottom U-shaped bent portion, be discharged by sewage draining exit.So, solve the problem of the organic matter long-time passive precipitation accumulation blocking pipe that organic discharge pipe inwall produces, make organic exhaust gas initiatively be condensate in U-bend portion, whole other positions of organic discharge pipe are accumulated less and does not even accumulate organic sediment.
As preferably, be provided with notch bottom described cooling water tank, notch is exposed and and airtight connection between notch in the bottom in U-bend portion.The bottom in U-bend portion is exposed notch and is facilitated blowdown.
As preferably, bottom sewage draining exit, be provided with collecting tank, between sewage draining exit and collecting tank, be provided with valve.
As preferably, the air inlet position of organic discharge pipe is provided with curve bend, described curve bend one end connects air inlet, and the curve bend other end is connected to the upper side of the vertical section bottom of organic discharge pipe, and the vertical section bottom of organic discharge pipe forms one section of liquid trap to connecting curve bend place.The vibrational power flow of curve bend makes the gas outlet of organic row's straight tube and sintering furnace not point-blank, prevents organic matter from passing back in sintering furnace.
As preferably, bottom described liquid trap, be provided with blowoff valve.
As preferably, the air inlet of organic row is set to horn-like.
The present invention has following beneficial effect: the photovoltaic sintering furnace exhaust gas processing device after improvement solves the problem of organic matter middle deposition backflow in organic discharge pipe of discharge.
