Description
Technical field
The utility model belongs to energy saving and environment friendly black sand ceramic kiln technical field, more particularly to a kind of energy saving and environment friendly
Black sand ceramic kiln.
Background technique
Black sand pottery is using a kind of pottery of clay and sand as primary raw material, its sand ingredient overweights other pottery classes, is belonged to
It makes pottery class in sand, Tao Genwei black, because of referred to herein as black sand pottery.Present black sand pottery has high temperature resistant, acid and alkali-resistance, aqueous, ventilative, guarantor
The functions such as temperature, therefore be widely used in tableware, drinking utensils, tea set, gardens Ke Jiyong device, medical and health special utensil etc..
Kiln is the equipment to burnt product being built into refractory material, is the indispensable facility in pottery art molding, the mankind
Up to ten thousand years ceramics burn makes history, have accumulated it is abundant make kiln pattern and experience, from the ground of primitive society it is outdoor it is burnt in a heap, dig pit
It builds and burns steamed bun shape liter flame circular kiln, half downdraf horse shoe flame furnace, half way up the mountain dragon kiln, oval kiln, then arrive Indoor Air kiln, electricity now
Kiln, kiln science and technology is in continuous improvement.
In the case where construction green energy conservation society tide pushes, people are to the expectation of Production of Ceramics process greenization and pursue increasingly
It improves, guarantees that production process lacks blowdown or not blowdown as far as possible using various method and apparatus.Ceramic product is in production process
In, due to burning fuel such as natural gas, liquefied gas, coal gas, light diesel fuel, heavy oil, coal etc., can release a large amount of sulphur compounds,
Fluorine compounds and oxynitrides, these harmful tail gas can cause significant impact to natural environment, cause the natural calamity such as acid rain
Evil, influences natural environment and human physical and mental health.It is imperative to develop ceramic kiln exhaust gas processing device.
During the preparation process, temperature is up to 1300 more to be spent black sand pottery, can equally generate a large amount of flue gas and dust, flue gas and
The harmful substances such as sulfide are usually contained in dust, therefore, it is necessary to carry out the vent gas treatment of kiln.
During ceramic sintering, the exhaust gas processing device of kiln has very much, such as application No. is:
201520531830.7 a kind of Ceramic manufacturing kiln exhaust gas processing device comprising heating device and ceramic kiln, ceramics
Kiln lower end is provided with heating device, and upper end is provided with the first smoke pipe on the right side of ceramic kiln, and the first smoke pipe and cyclone separator are left
Side upper end is connected, and is provided with crank in the first smoke pipe, crank both ends respectively with the axis that is symmetricly set on the first smoke pipe or more two sides
Cooperation is held, crank upper end is connected to the motor, but the prior art can not be handled the deleterious particle in tail gas, make its nothing
Method reaches emission request, and practicability is lower.
For another example, Chinese patent CN101695615A discloses a kind of composite acupuncture filtering for ceramic kiln fume treatment
Bag.Plain felt at composite acupuncture element felt, is handled staple fiber and base fabric needling shape by its technical characteristics using chemical treatments,
Then hot setting is made into filter bag.It is mainly used for handling the dust in ceramic kiln combustion product gases.

Want feature are as follows: flue gas burning and purifying device, hot air heat exchanger are set in sequence on flue gas circulation duct.Thermoregulation device, air-introduced machine
And radiator, pollution and the pre- heat utilization of progress are reduced by burn to flue gas and smoke pre-heating recycle.
Above kiln vent gas treatment all has certain defect, can not directly apply to and solve black sand Production of Ceramics mistake
The kiln vent gas treatment generated in journey.Main reason is that the exhaust gas in black sand ceramics sintering procedure is mainly derived from timber height
The VOC and flue gas volatilized when temperature is smouldered has temperature higher, and humidity is big, the big feature of dust.Timber is smouldered generation
VOC can be divided into two major classes.One kind is terpene and terpene compound, and carbon skeleton can be regarded as the multiple of isoprene and its contain
Oxygen derivative.Such as A-Pinene, B-pinene, camphene, limonene, laurene.Another kind of is non-terpenes volatile matter, mostly formic acid,
The organic acids such as acetic acid and propionic acid also include a small amount of pernicious gases such as formaldehyde, acetaldehyde and furfural.It is existing due to exhaust gas constituents complexity
Some emission-control equipments are difficult to solve.
In addition, these kilns all do not account for the efficiency of combustion of fuel, fail to consider energy conservation, generally existing section from source
The energy phenomenon that effect is unobvious, fuel economy is not high.
Therefore, how to solve the problems of the above-mentioned prior art becomes the direction of field technical staff effort.
