Description
Technical field
The present invention relates to a kind of process units of high purity quartz, the dress of high purity quartz is generated more particularly, to a kind of CVD
Put.
Background technology
The industrial production technology of quartz glass mainly include electric smelting technique, gas sweetening process, synthetic quartz glass manufacturing process,
High frequency plasma flame melting technology.Wherein synthetic quartz glass technology includes chemical vapor deposition (CVD) technique, gas phase axle again
To deposition (VAD) technique, plasma chemical vapor deposition (PCVD) etc..Quartzy glass of the CVD techniques in production large-diameter high-purity
There is greater advantage compared with other method in terms of glass, the quartz glass production of current large-diameter high-purity is general to be given birth to using CVD techniques
Production.
The quartz glass apparatus of CVD technique productions large-diameter high-purities is mainly made up of two large divisions, and a part is to provide
The reacting furnace of pyroreaction environment a, part is fixation, support, rotation, the tower body equipment of mobile product, and burner hearth is installed on tower body
Its upper side point.Large scale high purity quartz product because diameter, length, weight are all than larger, therefore production be usually on toward
Lower to carry out, i.e., blowtorch is arranged on upper furnace, and product is constantly deposited, constantly elongated, moves down, to make certain shape,
Sometimes left and right or movable is also carried out, product needs constantly to be rotated simultaneously in growth, these movements, rotation are all
Completed by accessories such as motor, guide rails, certainly because product is located at eminence, in addition it is also necessary to the device such as support, fix.These are matched somebody with somebody
Part, device etc. are referred to as tower body equipment.
Existing CVD production high purity quartz reacting furnace-e/or all uses single layer structure, and insulating brick is directly exposed to outside, held very much
Easy laying dust, does not allow easy to clean yet.Dust is easy to drop and entered in the product in burner hearth when therefore producing, and operating personnel need frequency
Numerous carry out inspection, chooses except the dust impurities in product in time, it is impossible to chooses the particle removed and directly results in product rejection, while insulating brick
Material is directly exposed to indoor not clean and tidy enough, attractive in appearance.Furnace high-temperature heat is directly radiated by blowtorch gap enters workshop condition
It is interior, indoor temperature can be caused too high, increase cooling cost.Using single layer structure, while to keep the air draft in furnace high-temperature, stove
Amount requires to keep the hydrogen chloride emission and silica dust that production is produced in seldom amount, such reacting furnace to be easy to spill into
In workshop, larger harm is produced to personal safety and company property.
The tower body equipment of CVD technique productions is all open type, does not form sealed nacelle and gas flowfield, and tower body etc. is filled
Residing bad environments are put, high temperature and perishable gas all have presence, and equipment easily produces exception, while dust etc. compares in environment
It is more, have influence on product quality.CVD technique tower body equipment traditional at present mainly has following defect：(1) by burner hearth temperature in tower body
Radiation effect is spent, temperature is higher, each device and accessory short life, exception easily occur, while fluctuation of service, influences product
Quality；(2) influenceed, each device and accessory easily corrode, short life, easily occurred by the hydrogen chloride tail gas that burner hearth overflows in tower body
It is abnormal, while fluctuation of service, influences product quality；(3) it is open environment, the particle such as dust in environment is easily accessible tower
In body, and then enter in the burner hearth room of product reaction, reduce product quality.
