Description
Technical field
The present invention relates to a kind of saving energy in kiln system, in particular to a kind of ceramic kiln energy saving system.
Background technique
As the market demand of ceramics is increasing, ceramic kiln also the more is built the more long, section is also more and more wide, but simultaneously
Kiln temperature is also increasingly difficult to control, and as kiln temperature it is uneven caused by the firing defects such as deformation, color difference
It is on the rise.
Meanwhile ceramic kiln is often using combustion gas as heat source, whether the proportion of combustion gas and air rationally directly affects when burning
To the size of energy consumption.When air capacity is very few, incomplete combustion, the substances containing a large amount of pollution environment in imperfect combustion product,
The waste of the energy is also resulted in simultaneously；And air capacity it is excessive when, excessive air be discharged when take away a large amount of heat again, increase heat
The loss of amount.
In addition, the fossil energies such as coal gas, natural gas are all non-renewable resources, gradually in the case where the mankind exploit on a large scale
It is exhausted.Moreover, these fuel discharge a large amount of toxic and harmful gas in burning Shi Huixiang air, Air seriously polluted is caused.
Biomass fuel (abbreviation BMF, such as agriculture and forestry organic waste material, such as stalk, sawdust, bagasse, rice chaff) has following
Several features: 1, to nature CO when the energy of BMF is from its growth2Absorption, therefore BMF have CO2Ecological " zero " discharge
The characteristics of；2, based on fugitive constituent, it is typical low-carbon fuel that the content of fixed carbon, which is 15% or so, for the burning of BMF；3,
The sulfur content of BMF is also lower than diesel oil, and only 0.05%, it is not required to setting desulfurizer and achieves that SO2Discharge；4, the ash of BMF
Part it is only 1.8%, is 1/10 of coal derived fuel or so, simple dust-extraction unit is arranged, and to can be achieved with dust emission up to standard；5,BMF
Nitrogen content is low, and oxygen content is high, and when burning generates less NOX；6, BMF derives from agriculture and forestry organic waste material, and feed distribution is various extensively,
At low cost, cycling deposition is inexhaustible, is typical circular economy project.
However, industry does not develop the mature equipment and technology that biological fuel gas is used for ceramic kiln also so far.
A kind of ceramic kiln oxygen-enriched combustion-supporting energy saver as disclosed in Chinese patent discloses No. 104006405A, belongs to pottery
The technical field of energy saving and environmental protection of porcelain kiln.The device includes that the oxygen-enriched membrane component, water ring vacuum pump, oxygen rich gas being sequentially connected delay
Rush tank, booster fan and burner；Burner includes burner tube body, main air supply duct, fuel conduit and burner nozzle,
Wherein: burner tube body it is closed at one end, the other end connect burner nozzle, burner tube body be it is multiple；Booster fan passes through
Oxygen rich gas pipeline connects main air supply duct, and fuel conduit and main air supply duct are connect with each burner tube body respectively；Master send
Air piping connects main breeze fan.However, the ceramic kiln oxygen-enriched combustion-supporting energy saver has the following disadvantages or insufficient: (1), its
Using rich oxygen generation system, the cost of equipment is on the one hand increased, another aspect oxygen-enriched combusting necessarily leads to the dioxy in flue gas
Change carbon content is excessively high, and the carbon emission reduction concept advocated energetically with current energy-saving field is runed counter to；(2), its fuel gas conduit and air hose are adopted
With integrated control, it can not achieve and each section of ceramic kiln is accurately controlled respectively.
For another example it is oxygen-containing to disclose sectional adjusting hot gas on a kind of ceramic kiln of No. 203273939U announcement for Chinese patent
The energy saver of amount, ceramic kiln are high temperature firing area kiln, introduce the air inlet general pipeline of combustion air, furnace into kiln including one
In each section of different kiln of interior temperature, it is respectively equipped with respectively independent and parallel with air inlet general pipeline air inlet and is in charge of, every section of air inlet
It is in charge of and enters the wind between general pipeline, interval is connected with the automatic valve that can automatically adjust intake size and manually adjustable air inlet
The hand-operated valve for measuring size is in charge of and automatic valve, hand-operated valve due to being provided with air inlet, can automatic or manual adjust helping for each section of kiln
Fire wind size.However, the energy saver that sectional adjusts hot gas oxygen content on the ceramic kiln has the following disadvantages or deficiency:
(1), it is only able to achieve to the sectional-regulated of air inlet, and can not achieve to the sectional-regulated of combustion gas；(2), it uses coal gas to act on
Fuel, it is at high cost and do not meet environmentally protective theory；(3), its burner and kiln one-piece construction, this is unfavorable for according to ceramics
The size of kiln arbitrarily increases or decreases burner mould group.
Therefore it provides a kind of ceramic kiln system that can be realized the control of accurate segmentation area, reduce CO2 emissions
As urgent problem in the industry.
