Tape casting, rolling formation, hydrostatic profile etc..Wherein dry-pressing formed and injection forming, tape casting because ripe technique it is wide
Application range occupies absolute status.But three kinds of main pollution sources of moulding process are binding agent and plasticizer, wherein bonding
Agent mainly has：Polyvinyl alcohol, methylcellulose, polyvinyl alcohol, butyral, macrogol, carboxymethyl cellulose, ethyl are fine
Tie up element, carboxy-propyl cellulose, paraffin etc.；Plasticizer mainly has：Glycerine, two fat of metatitanic acid fourth, acetic acid triethylene glycol.With whole people's environmental protection
The raising of consciousness, environmentally friendly requirement is also higher and higher in being produced to special cermacis.In order to reach qualified discharge, for above-mentioned technique
Generation waste gas processing method is burnt till in production mainly to be had：Flue gas secondary combustion, ultraviolet and ozone decompose, and photocatalyst decomposes, chemistry
Spraying neutralization, spray cooling precipitation, filtration, purification, wherein processing means have one or more joints.Wherein ultraviolet and ozone point
Solution, photocatalyst decomposition, chemical spray neutralization, spray cooling precipitates, filtration, purification is because processing cost is relatively higher, and plant maintenance is numerous
It is trivial or be also easy to produce secondary pollution.Binding agent and plasticizer main component are C, and tri- kinds of elements of H, O are easily decomposed into CO at high temperature2
And H2Flue gas is generally imported secondary combustion chamber by O, therefore take second-time burning relatively reasonable, second-time burning, high-temperature process, fully
Qualified discharge or existing environment-protection kiln take high temperature kiln and low temperature de-waxing dumping kiln burner hearth intercommunication or common wall after burning,
The flue gas injection high temperature kiln burning that low temperature kiln is generated, low temperature kiln are heated using the intercommunication or common metope of high temperature kiln
Reach temperature.The first flue gas needs additional Combustion Source, and energy consumption is very high, and heat does not make full use of.In addition existing environmental protection
Kiln, disjunctor construction is of high cost, although UTILIZATION OF VESIDUAL HEAT IN, low-temperature flue gas injection high-temperature burner hearth is unfavorable for high temperature sintering, influences
Atmosphere.Medium temperature kiln passively heats, and high temperature and low-temp. hearth influence each other, and is unfavorable for heating curve control.Kiln body product occurs
Rupture or kiln furnitures be easy to cause accident when damaging, and are inconvenient to repair.
The content of the invention
It is an object of the present invention to overcome the above-mentioned technical problems, and to provide a kind of environmentally friendly de-waxing dumping kiln, the kiln rings
It protects, construction cost is low, convenient for control, kiln body subregion synthesis, convenient for safeguarding.
The technical solution for solving above-mentioned technical problem is as follows：
A kind of environmental protection de-waxing dumping kiln, including kiln body, kiln body bottom sets a track, and the kiln body is left
Side set kiln import, right side set kiln export, kiln body include combustion chamber, preheating zone, flue gas leak proof region, cooling zone and
Cooled flue gas leak proof region, preheating zone set preheated burning room, and flue gas leak proof region is located at the left side of preheated burning room and is fired with preheating
Room connection is burnt, preheating zone is located at the left side of combustion chamber, is connected among the preheating zone and combustion chamber by furnace body non-combustion chamber,
It is connected with cooling zone and cooled flue gas leak proof region on the right side of combustion chamber in turn, preheating zone is connected with combustion chamber by flue, described
Cooling zone is also equipped with flue, and combustion chamber and preheated burning room are both provided with fixed nozzle, air-introduced machine are serially connected on flue.
It further says, the fixed nozzle is fixed by high temperature resistant hole brick.
It further says, the cooled flue gas leak proof region includes steelframe, and steelframe top sets a flame retardant coating, and described is resistance to
The outside of fire bed is covered by insulating layer, is additionally provided with separation layer outside the insulating layer, the cooled flue gas leak proof region with
Flue gas leak proof region has identical structure.
It further says, the combustion chamber is provided with temperature thermocouple.
It further says, the kiln import prevents that gas is excessive by the way of burner hearth internal diameter is reduced.
It further says, the air-introduced machine is speed-changing draught fan, keeps kiln tiny structure.
900 DEG C -1300 DEG C of kiln Applicable temperature scope；
The applicable energy is：Natural gas or liquefied gas；
Applicable craft：Medium temperature or low temperature de-waxing or dumping；
Suitable application area：Special cermacis produces；
Kiln body length makes according to actual demand.
Handling capacity will lengthen greatly flue gas leakproof section length or increase air inducing fan delivery, be protected when increasing air inducing fan delivery
Flue gas is demonstrate,proved in combustion chamber or burner hearth high-temperature region by the time, prevents that smoke combustion is insufficient.
The outer one side of kiln furnace body, the rails of parallel identical span form annular, the both ends parallel cunning of inductor control
Rail can form semi-automatic flow line production, cost-effective.
The beneficial effects of the invention are as follows：
The kiln takes orbital fashion to run, and propulsion mode is easy, and resistance is small, reduces the abrasion of kiln refractory material, favorably
In saving production cost；Particular for hot pressing casting process, the heat that paraffin includes in itself is taken full advantage of, the energy is greatly reduced
Consumption.
Polyvinyl alcohol, methylcellulose, polyvinyl alcohol, butyral, macrogol, carboxymethyl cellulose, ethyl cellulose
Element, carboxy-propyl cellulose, paraffin, glycerine, two fat of metatitanic acid fourth, acetic acid triethylene glycol.At 900-1300 DEG C, fully burning can ensure that clear
Clean discharge odorlessness.Compared to pervious environment-protection kiln, the kiln, construction cost is low, and convenient for control, kiln body subregion synthesizes, just
In maintenance.The kiln production life cycle promotes, and continuous production, burner hearth is small, constant temperature, convenient for temperature control.
