Abstract
The invention discloses a kiln tail high-temperature dust collection device for a rotary kiln, which comprises a high-temperature dust collection bag. The high-temperature dust collection bag is provided with a feeding pipe which is connected with a preheater and is used for conveying flue gas, and a discharge pipe which is connected with a kiln tail fan and is used for conveying processed gas; a collection region which is communicated with the feeding pipe and is provided with a plurality of collection bags for processing the flue gas, and an exhaust region which is communicated with the discharge pipe and is used for exhausting the processed gas are contained in the high-temperature dust collection bag; the exhaust region is disposed at the upper part of the collection region; a separator with a through hole is arranged between the exhaust region and the collection region; an elastic rubber ball in air tightness connection with the through hole of the separator is arranged in the exhaust region; the rubber ball is connected with a one-way exhaust pipe capable of exhausting gas in the rubber ball; the one-way exhaust pipe is a hose. According to the device, the one-way exhaust pipe is made of a flexible material and can exert rapid opening and closing functions so as to enable the integral dust collection device to achieve the best dust collection effect.
Description
Technical field
The present invention relates to cement process equipment, specifically, relate to a kind of rotary kiln high temperature dust arrester installation.
Background technology
At present, the long bag pulse bag dust collector of cement production enterprise production line kiln tail dust collecting system many employings high-temperature low-pressure.Prior art (CN202024594U) gives one " rotary kiln high temperature gather dust pocket outlet valve ", and it utilizes the mechanisms such as cylinder that outlet valve is controlled.But, the outlet valve of this kind of structural design yet suffers from opening, closing not in time, will result directly in flue gas and bottles up in pocket and cannot be expelled in rotary kiln blower fan from discharge nozzle, has a strong impact on the normal production of cement production enterprise.
Summary of the invention
For the deficiencies in the prior art, it is an object of the invention to provide a kind of rotary kiln high temperature dust arrester installation, the outlet that this dust arrester installation can realize between exhaust gas region and collecting zone opens and closes rapidly, and then makes dust collection effect the best of whole dust arrester installation, and production efficiency is high.
nullFor achieving the above object，The present invention is achieved by the following technical solutions: a kind of rotary kiln high temperature dust arrester installation，Including high temperature dust collecting sleeve，Described high temperature dust collecting sleeve is provided with and is connected with preheater and for the feeding pipe of supplied flue gases、It is connected with kiln a tail wind machine and is used for the discharge nozzle of gas after transport process，Include, in described high temperature dust collecting sleeve, the collecting zone being connected and being provided with some collecting bags for processing flue gas with feeding pipe、It is connected with discharge nozzle and for discharging the exhaust gas region of gas after process，Described exhaust gas region is placed in the top of collecting zone，A dividing plate with through hole it is provided with between described exhaust gas region and collecting zone，Described exhaust gas region is provided with the gum elastic ball that the through hole air-tightness with dividing plate is connected，Described ball is connected to the one-way exhaust pipe that can be discharged by the gas in ball，Described one-way exhaust pipe is soft pipe.
Further illustrating, described through hole is placed in the center of dividing plate.
Further illustrating, described one-way exhaust pipe is dismountable.
Further illustrating, the gas outlet of described one-way exhaust pipe is outside discharge nozzle.
Compared with prior art, there is advantages that the structure that traditional air cylinder structure is modified into gum elastic ball by this device and one-way exhaust pipe matches, when there is air pressure in collecting zone, ball is made to expand, gas is discharged from one-way exhaust pipe and is realized the current of air-flow, and makes the gas in exhaust gas region be expelled in rotary kiln blower fan by discharge nozzle.It addition, after collecting zone air pressure disappears, owing to one-way exhaust pipe adopts soft material to make, under the effect of ambient pressure, one-way exhaust pipe is crowded flat, thus realizing the closedown to passage, and then the gas channel between isolation collecting zone and exhaust gas region.This device adopts soft material to make one-way exhaust pipe can play the function of quickly opening and closing, and then makes the dust collection effect of whole dust arrester installation best, and production efficiency is high.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, but is not intended to protection scope of the present invention and range of application:
nullAs shown in Figure 1，A kind of rotary kiln high temperature dust arrester installation，Including high temperature dust collecting sleeve 1，High temperature dust collecting sleeve 1 is provided with and is connected with preheater and for the feeding pipe 2 of supplied flue gases、It is connected with kiln a tail wind machine and is used for the discharge nozzle 5 of gas after transport process，The collecting zone being connected and being provided with some collecting bags 4 for processing flue gas with feeding pipe 2 is included in high temperature dust collecting sleeve 1、It is connected with discharge nozzle 5 and for discharging the exhaust gas region of gas after process，Exhaust gas region is placed in the top of collecting zone，A dividing plate 3 with through hole it is provided with between exhaust gas region and collecting zone，Exhaust gas region is provided with the gum elastic ball 6 that the through hole air-tightness with dividing plate 3 is connected，Gas leakage can be avoided，Ball 6 is connected to the one-way exhaust pipe 7 that can be discharged by the gas in ball 6，One-way exhaust pipe 7 is soft pipe，It can be such as soft pvc pipe、Soft rubber tube、Soft silicone tube etc..One-way exhaust pipe 7 is dismountable, during as damaged, it is easy to change.The gas outlet of one-way exhaust pipe 7 is outside discharge nozzle 5 so that it is quick, convenient that gas is discharged, and can reduce gas delay in exhaust gas region simultaneously.Preferably, through hole is placed in the center of dividing plate 3, and it is more quick and easy that this kind of structural design can make one-way exhaust pipe 7 open or close.
The structure that traditional air cylinder structure is modified into gum elastic ball 6 by this device and one-way exhaust pipe 7 matches, when there is air pressure in collecting zone, ball 6 is made to expand, gas is discharged from one-way exhaust pipe 7 and is realized the current of air-flow, and makes the gas in exhaust gas region be expelled in rotary kiln blower fan by discharge nozzle 5.It addition, after collecting zone air pressure disappears, owing to one-way exhaust pipe 7 adopts soft material to make, under the effect of ambient pressure, one-way exhaust pipe 7 is crowded flat, thus realizing the closedown to passage, and then the gas channel between isolation collecting zone and exhaust gas region.This device adopts soft material to make one-way exhaust pipe 7 can play the function of quickly opening and closing, and then makes the dust collection effect of whole dust arrester installation best, and production efficiency is high.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, it is impossible to assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention; make some equivalent replacements or obvious modification without departing from the inventive concept of the premise; and performance or purposes are identical, the scope of patent protection that the present invention is determined all should be considered as belonging to by submitted claims.
