Abstract
The utility model relates to an inclination furnace for treating inclination of waste gas and waste liquid. The inclination furnace is characterized in that a furnace body is formed by the connection of a primary combustion chamber and a secondary combustion chamber; a gas combustor is arranged between the primary combustion chamber and the secondary combustion chamber; a cooling blower is connected with the primary combustion chamber, the secondary combustion chamber and the gas combustor respectively through an air feeding pipe; a combustion-supporting blower is connected with the gas combustor through a communication pipe; and an exhaustion pipeline is arranged at the bottom of the secondary combustion chamber. The waste gas, the waste liquid and the natural gas generated in the production process of the polycrystalline silicon are fully mixed and burned at a high-speed rotation state, and the combustion-supporting air enters the furnace in a tangential way to help the combustion smoke gas to rotate so as to form vortex and support combustion; in addition, the waste gas, the waste liquid and the natural gas are fully burned in the furnace and subjected to high-temperature hydrolysis to obtain high-temperature smoke gas containing SiO2, HCl, CO2, N2,Cl2 and the like for post-process treatment recycling.
Description
Technical field
The utility model relate to the high concentration chlorine contained exhaust gas of association in the polysilicon production process and chloride waste liquid carry out purified treatment technical field, specifically a kind ofly be used for handling the waste gas of polysilicon production process association, the incinerator of liquid waste incineration.
Background technology
Present domestic polysilicon industry, the main processing means to waste gas and waste liquid are hydrolysising alkali absorption processes at present, and this law technology is simple, and cost is lower.But treatment effect is very poor, and secondary pollution is very serious, and comprehensive utilization recovery ability is low.Because chlorosilane is poisonous and harmful liquid or the gas with severe corrosive in waste gas, the waste liquid, simultaneously also with hydrogen, therefore burn dry process as adopting, the most basic requirement is to burn clear fully and burning process safety to incinerator, the variation adaptability that waste gas, waste liquid are formed is strong simultaneously, and the incinerator of prior art still can not reach such effect.
Summary of the invention
The purpose of this utility model is to provide a kind of improved incinerator that is used to handle waste gas, liquid waste incineration, and it can overcome in the prior art waste gas and liquid waste processing poor effect, and secondary pollution is very serious, the low some shortcomings of comprehensive utilization recovery ability.
To achieve these goals, the technical solution of the utility model is: a kind of incinerator that is used to handle waste gas, liquid waste incineration, it mainly comprises body of heater, with the cooling blower that links to each other with body of heater, combustion fan, it is characterized in that: body of heater is formed by connecting by first, second grade combustion chamber, first, second grade is provided with gas burner between the combustion chamber, cooling blower links to each other with first, second grade combustion chamber and gas burner respectively by ajutage, combustion fan linked to each other with gas burner by communicating pipe, and the bottom of combustion chamber, the second level is provided with discharge duct.
Carry out burning disposal after waste gas of the present utility model, waste liquid enter during use, burn clear fully, process stabilization, safe and reliable.The utlity model has following advantage:
1, in the process of carrying out polysilicon waste gas and waste liquid integrated treatment, this incinerator not only can be handled waste gas, waste liquid but also can handle waste gas or waste liquid separately, can both obtain satisfied result; Have environmental protection and economical effects;
2, the combustion-supporting fuel that the utility model uses can be diversified, and natural gas, hydrogen hydrogen, diesel oil all are to use;
3, the utility model can make the flue gas formation eddy current rotation that waste gas, waste liquid produce in incinerator, guarantees that high-temperature hydrolysis is clear fully entirely;
4, the temperature of incinerator and gas residence time are regulated and control accurately according to technological requirement
5, incinerator has strictness, reliable safety precautions.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
The utility model mainly comprises body of heater, with the cooling blower that links to each other with body of heater, combustion fan, it is characterized in that: body of heater is formed by connecting by combustion chamber 8 and reative cell 10, the top of combustion chamber is provided with igniter 7, the top of igniter is provided with fuel inlet, the both sides of combustion chamber are provided with air inlet, and the bottom of reative cell is provided with discharge duct.(igniter is a prior art, has just no longer narrated its operation principle here).Fuel inlet has three, is respectively exhaust gas inlet 2, mixes gas-liquid import and compressed air inlet 6, mixes gas-liquid import top and is provided with natural gas import 3, diesel oil import 4 and waste liquid import 5.One side of combustion chamber is provided with cooling air import 1, and opposite side is provided with combustion air inlet 9.Cooling air import and combustion air inlet place are equipped with by-pass valve control.The surface of reative cell is provided with heat-insulation layer 11.
In force, incinerator is vertical, and entire arrangement is opened wide half, in the frame concrete structure factory building.The waste gas, waste liquid and the natural gas via that produce in the polysilicon production process are fully mixed, under the state of rotation at a high speed, fully burn, because import department is provided with an angle of cutting sth. askew, make combustion air enter the combustion chamber in the mode of tangent line, help combustion product gases to produce rotation and form eddy current and combustion-supporting, fully burn in the stove, behind the pyrohydrolysis, obtain containing the high-temperature flue gas of SiO2, HCl, CO2, N2, Cl2 etc.Reclaim heat energy, aerosil and hydrogen chloride for subsequent handling.Incinerator is made up of valve group, igniter, combustion fan, cooling blower, body of heater, adopt low pressure parameter, outdoor layout, anti-8 degree earthquake intensity designs, that chlorosilane waste gas, waste liquid burn in incinerator is clear fully, process stabilization, safe and reliable, this technology are not seen domestic report as yet with device, belongs to domestic initiation.The operation principle of incinerator is based on fuel hydrogen or natural gas (CH4) reacts with airborne oxygen (will send into combustion air and cooling air during burning) in stove, produces steam and high temperature simultaneously, specifically reacts as follows: 2H
2+ O
2---2H
2O; CH
4+ O
2-2H
2O+CO
2
After waste gas, the waste liquid of chlorine-containing silane enter incinerator, the high-temperature thermal oxidation hydrolysis can take place, be example: 2SiHC with trichlorosilane (TCS)
3+ 4H
2O-2SiO
2+ HCl+2H
2
In order to guarantee to enter complete, the clear burning of waste gas, waste liquid in the incinerator, key will be controlled incineration temperature well, flue gas is the left alone without help time of staying in stove, (said temperature, time conditions are prior art for air current composition and the characteristic that flows in stove and burning safety, here just its concrete data have been repeated no more), for guaranteeing safety, except that the combustion managing system (BMS) that is provided with PLC control, be micro-pressure operation during incinerator work.
