Description
Technical field
The utility model relates to tail gas disposal technique field, is specially a kind of rotary kiln exhaust gas treating apparatus.
Background technology
Rotary kiln refers to rotary calcining kiln (being commonly called as rotary kiln), belongs to building equipment class.Rotary kiln can be divided into cement kiln, chemical metallurgy kiln and limekiln by material handling difference.Cement kiln is mainly used in calcination of cement clinker, divide dry production cement kiln and the large class of wet production cement kiln two, chemical metallurgy kiln is then mainly used in the poor iron ore magnetic roasting of metallurgy industry steel plant, a large amount of tail gas can be produced after calcined by rotary kiln, containing a large amount of heats and dust in tail gas, be discharged in air and pollute the environment, need to process tail gas.Filter in existing tail gas treatment device not only changes trouble, and the replacement cycle is short, waste the plenty of time, and adding cost, the dust cleaning under existing treatment facility filters is inconvenient and cleaning is unclean, and some treatment facility then needs to stop the work of rotary kiln to clear up dust, the normal production of factory is caused to be obstructed, affect the benefit of factory, for this reason, we propose a kind of rotary kiln exhaust gas treating apparatus.
Utility model content
The purpose of this utility model is to provide a kind of rotary kiln exhaust gas treating apparatus, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of rotary kiln exhaust gas treating apparatus, comprise process tank, air inlet pipe is provided with on the downside of the sidewall of described process tank, the upper surface of described process tank is provided with blast pipe, in the middle part of the inner chamber of described process tank, heat exchanger is installed, filter is movably installed with by bolt on the upside of the inner chamber of described process tank, the top and bottom of described bolt are socketed with spring respectively, round table-like dust collecting trough is left in the downside of described process tank, dust export is left in the bottom of described dust collecting trough, the bottom of described dust export is provided with changeover valve by turning cylinder, described turning cylinder is circumscribed with electric rotating machine by transmission device.
Preferably, the limited block for changeover valve location is left in the lower end of described dust export.
Preferably, the inner chamber of described heat exchanger is provided with the heat exchanger tube of dish type, and the import and export of described heat exchanger tube runs through the tube wall of process tank respectively.
Preferably, the tube wall of described heat exchanger tube leaves annular lug.
Compared with prior art, the beneficial effects of the utility model are: this treating apparatus adopts the structure of bolt socket spring fixed filter unit, filter is ceaselessly shaken washing away of tail gas, dust in tail gas is not easily adsorbed on filter, cause the obstruction of filter, extend the service life of filter, save processing cost, adopt the structure of dust collecting trough and changeover valve, dust cleaning work is made to become convenient, and do not need the work stopping rotary kiln, keep the normal operation of factory.
