Abstract
The invention discloses a waste gas treatment structure of a ceramic mist spraying and drying tower. The structure comprises a hot gas channel and a waste gas channel which extend from a ceramic kiln to the lower portion of the mist spraying and drying tower. The mist spraying and drying tower is communicated with a cyclone dust collector, one or two or more waste gas exhaust pipes are transversely wound around the middle of the outer wall of the mist spraying and drying tower, the waste gas channel is communicated with each exhaust pipe through a longitudinal waste gas pipe, each exhaust pipe is communicated with an inner cavity of the mist spraying and drying tower through multiple transverse small gas pipes, and all the small gas pipes are evenly distributed along the circumferences of the exhaust pipes. By means of the structure, high-temperature waste gas can be subjected to desulphuration and denitration so that sulphur, nitre and other harmful components in the high-temperature waste gas can be effectively removed, and a good environment-friendly effect can be achieved.
Description
Technical field
The present invention relates to ceramic device, particularly a kind of exhaust-gas treatment structure of Spraying Dryer of Ceramics.
Background technology
Ceramic kiln comprises dry section, dehumidifier district, preheating zone, firing zone, quench zone, slow cooling district and the fast cold-zone of kiln tail successively, in Production of Ceramics, the high-temp waste gas with a large amount of dust and the oxious component such as sulfur-bearing, nitre extracted out from kiln dry section and dehumidifier district, need to carry out environmental protection treatment, but existing exhaust treatment system, often not ideal to the environmental protection treatment of waste gas.
Summary of the invention
The technical problem to be solved in the present invention, is to provide a kind of exhaust-gas treatment structure of Spraying Dryer of Ceramics, can reaches very good environment protecting.
For solving the problems of the technologies described above, technical scheme of the present invention is: the exhaust-gas treatment structure providing a kind of Spraying Dryer of Ceramics, comprise and extend to hot gas ditch below spray drying tower and waste gas ditch from ceramic kiln, spray drying tower is communicated with in succession with cyclone dust collectors, in the middle part of the outer wall of spray drying tower, lateral loops is wound with the blast pipe of more than one or two waste gas, between waste gas ditch and every root blast pipe, be communicated with the flue gas leading of a longitudinal direction, between every root blast pipe and the inner chamber of spray drying tower, be communicated with some horizontal tracheoles, all tracheoles are arranged along the even circumferential of blast pipe.
The exhaust-gas treatment structure of Spraying Dryer of Ceramics as above, hot gas ditch and waste gas ditch, all through the by-pass valve control of automatic or manual, are communicated with exhaust-gas treatment ditch
Said structure, owing to can utilize the ceramic size with alkalescence in spray drying tower, carries out sulphur removal except nitre process to high-temp waste gas, thus effectively can remove the oxious component such as sulphur, nitre in high-temp waste gas, can reach very good environment protecting.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the schematic front view of described embodiment;
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
Detailed description of the invention
See Fig. 1-Fig. 2, a kind of exhaust-gas treatment structure of Spraying Dryer of Ceramics is provided, comprise and extend to hot gas ditch 1 below spray drying tower and waste gas ditch 2 from ceramic kiln, spray drying tower is communicated with in succession with cyclone dust collectors 3, in the middle part of the outer wall of spray drying tower, lateral loops is wound with the blast pipe 4 of three waste gas, between waste gas ditch 2 and every root blast pipe 4, be communicated with the flue gas leading 5 of a longitudinal direction, between every root blast pipe 4 and the inner chamber of spray drying tower, be communicated with some horizontal tracheoles 6, all tracheoles 6 are arranged along the even circumferential of blast pipe 4.
In work:
Hot blast from hot-blast stove enters spray drying tower from tower top, carries out drying process to ceramic size.
Be sent to a part of waste gas in waste gas ditch 2, through flue gas leading 5, three blast pipes 4 and some tracheoles 6, enter in spray drying tower, on the one hand, hot blast carries out drying process to ceramic size, make ceramic size become graininess to fall, on the other hand, alkali components in ceramic size, be full of in the inner chamber of a large amount of steam at spray drying tower, with the sulphur in high-temp waste gas, nitre composition generation chemical reaction, generate water-fast solid particle, fall with ceramic particle, collecting can for the production of Ceramic Tiles, thus the sulphur can effectively removed in high-temp waste gas, the oxious components such as nitre, very good environment protecting can be reached.Sulphur removal, except the waste gas after nitre process, after cyclone dust collectors 3 dedusting, continues to be sent to exhaust-gas treatment ditch 7 downwards, and by the environment-friendly processing unit separately established, such as dry wet dual dust pelletizing system and desulfurizing tower, realize the process completely of waste gas.
See Fig. 1, hot gas ditch 1 and waste gas ditch 2 all through the by-pass valve control 8 of automatic or manual, are communicated with exhaust-gas treatment ditch 7.In Production of Ceramics, when the hot gas amount be sent in waste gas ditch 2 and exhausted air quantity large especially time, by-pass valve control 8 can be opened by automatic or manual, the portion processed is had little time in the course of work of above-mentioned hot-blast stove and spray drying tower, also exhaust-gas treatment ditch 7 can be entered, by environment-friendly processing unit, carry out the environmental protection treatment of this part waste gas.
Above-described embodiment is the preferred embodiments of the present invention, and all structures similar with the present invention and the equivalence done change, and all should belong to protection category of the present invention.
