Abstract
The utility model relates to an energy saving oxidation furnace which belongs to the field of carbon fiber production equipment. The energy saving oxidation furnace is provided with an oxidation furnace; the outlets and the inlets of both ends of the oxidation furnace are provided with upper layers of halls and lower layers of halls; the upper layers of halls and the lower layers of halls are provided with exhaust ports; the exhaust ports are arranged at the middle front parts of both sides of the upper parts of the halls; the halls are provided with channels in the same number with oxidation furnace channels; regulating shutters are arranged above and below the channels. The oxidation furnace has quite low outer surface temperature and small heat consumption; the inlets and the outlets of the oxidation furnace do not leak hot air, and the heat radiation at the furnace mouth is small; the isothermal region in the hearth of the oxidation furnace is long, which can improve the production capability.
Description
Technical field
The utility model is a kind of carbon fiber production equipment, specifically the energy-saving oxidation furnaces in the carbon fiber production process.
Background technology
As everyone knows, a complete carbon fibre carbonizing production line mainly is made up of following equipment: threading running out machine, oxidation furnace, carbide furnace, surface processing equipment (electrolysis machine, rinsing machine, starching machine and drying oven), drive unit, receipts silk machine and other corollary equipments etc.
The main raw material(s) of producing carbon fiber is a polyacrylonitrile-based precursor, undressed precursor is a combustible material, be easy to burning at normal temperatures, carry out pre-oxidation treatment so must will be introduced into pre-oxidation furnace at the preceding precursor of high temperature cabonization (temperature is between 400 ℃～1500 ℃), pre-oxidation treatment is an oxidation, dehydrogenation, denitrogenation, the process of cyclisation, reach carbon by this process, the purpose of oxygen element enrichment and fiber typing, final purpose is to make the linear molecule chain of polyacrylonitrile fibril be converted into heat-resisting trapezoidal molecular chain structure pattern, make it when high temperature cabonization, keep fiber form and do not burn, be " not burning processing " process so the pre-oxidation treatment process also is commonly called as.Also can draw a conclusion thus, pre-oxidation furnace is one of key equipment of producing by the high-quality carbon fiber.
The major function of pre-oxidation furnace is carried out pre-oxidation treatment to precursor exactly, with regard to present each employed oxidation furnace of carbon fiber manufacturer, all in various degree exist some problems, conclude as follows: 1, the oxidation furnace hull-skin temperature is higher, and the thermal energy loss is big; 2, it is serious that the entrance and exit of oxidation furnace leaks hot blast, and the high temperature that heat radiation produces makes the operating personnel can not be near fire door; 3, isothermal region falls short of in the oxidation furnace burner hearth, has restricted the further raising of production throughput.
Summary of the invention
In order to solve the deficiency of above-mentioned existing equipment technology, the purpose of this utility model provides a kind of energy-saving oxidation furnace, and this oxidation furnace hull-skin temperature is lower, and the thermal energy loss is little; The entrance and exit of oxidation furnace is not revealed hot blast, and fire door place thermal radiation is little; The isothermal head of district in the oxidation furnace burner hearth can improve production throughput.
The utility model adopts following technical solution: be provided with the oxidation furnace body, the outlet at oxidation furnace body two ends and entrance location place all are equipped with entrance hall, upper strata and lower floor entrance hall, entrance hall, upper strata and lower floor entrance hall are respectively equipped with exhaust outlet, exhaust outlet lays respectively at the middle front part position of both sides, top, entrance hall, the corresponding oxidation furnace passage in entrance hall is provided with the passage of equal number, and passage is equipped with the adjusting flashboard up and down.
The beneficial effects of the utility model are: this oxidation furnace hull-skin temperature is lower, and the thermal energy loss is little; The entrance and exit of oxidation furnace is not revealed hot blast, and fire door place thermal radiation is little; The isothermal head of district in the oxidation furnace burner hearth can improve production throughput.
