Abstract
The utility model discloses a fumed silica deacidification furnace. The furnace comprises a steam input section, a heating section and an expanding separation section, wherein ten groups of quartz tubes are transversely arranged in the heating section; a U-shaped quartz tube is vertically arranged in the expanding separation section; the end of the U-shaped quartz tube is in seal connection with the furnace wall of the deacidification furnace through a flange; and the U-shaped quartz tube is in 220V constant-voltage connection with a power source. The deacidification furnace has the advantages of higher heating efficiency, longer service life and more convenient replacement of the quartz tubes, good deacidification effect and less hydrogen chloride vapor condensation.
Description
Technical field
The utility model relates to the depickling stove, is specifically related to a kind of thermal silica depickling stove.
Background technology
In the thermal silica production process, the hydrogen chloride gas in the thermal silica of the state of aggregation meeting absorption reaction just need remove hydrogenchloride to the white carbon black heating in the depickling stove.The structure of depickling stove comprises: steam input section, heating zone and expansion segregation section, steam input section is provided with the superheated vapour inlet, the bottom of heating zone is provided with the thermal silica inlet, heating zone laterally is provided with 10 groups of silica tubes, enlarge segregation section and be provided with thermal silica outlet and sour vapor outlet, enlarging segregation section also is provided with equipment support and observes visor, the termination of silica tube is tightly connected by filler and furnace wall, the power supply mode of connection of silica tube is that the star angle conversion of 380/220V connects, and the silica tube in the depickling stove is straight type silica tube at present.Because straight type silica tube heating-surface area relative narrower, heating efficiency is lower, and deacidification effect is undesirable.And only be provided with silica tube, enlarge segregation section and do not establish,, enlarge segregation section and occur hydrogenchloride condensation vapor phenomenon easily, corrosion depickling stove if the equipment reason is often stopped in heating zone.Packing seal connects more loaded down with trivial details to the replacing of silica tube, and the sealing stability of filler is also relatively poor; The silica tube power supply mode of connection of star angle conversion, superheating phenomenon often appears in silica tube, and silica tube is easily burnt out, in case silica tube burns out, depickling stove heating zone can heat non-uniform phenomenon, also influences deacidification effect, and quality product is descended.
Summary of the invention
It is higher that technical problem to be solved in the utility model provides a kind of heating efficiency, and silica tube is longer relatively work-ing life, and deacidification effect is better, and silica tube is changed more convenient, the thermal silica depickling stove that the hydrogenchloride condensation vapor is less.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of thermal silica depickling stove, comprise steam input section, heating zone and expansion segregation section, described heating zone laterally is provided with 10 groups of silica tubes, described expansion segregation section vertically is provided with silica tube, described silica tube is a U type silica tube, the termination of described U type silica tube is tightly connected by the furnace wall of flange and depickling stove, and the power supply mode of connection of described U type silica tube connects for the 220V constant voltage.
Compared with prior art, advantage of the present utility model is a kind of thermal silica depickling stove, comprise steam input section, heating zone and expansion segregation section, heating zone laterally is provided with 10 groups of silica tubes, enlarge segregation section and vertically be provided with silica tube, silica tube is a U type silica tube, and the termination of U type silica tube is tightly connected by the furnace wall of flange and depickling stove, and the power supply mode of connection of U type silica tube connects for the 220V constant voltage; U type silica tube is bigger with respect to straight type silica tube heating-surface area, and heating efficiency is higher, and deacidification effect is better; Enlarge segregation section and also be provided with U type silica tube, both can improve deacidification effect, can use as companion's heat of depickling stove in device driving or shutdown phase again, reduced the hydrogenchloride condensation vapor phenomenon in the depickling stove, the life-span of having improved equipment; The flange seal of silica tube connects, the sealing good stability, and it is also convenient to change silica tube; U type silica tube constant voltage power supply mode of connection, silica tube superheating phenomenon can not occur, and work-ing life is just longer, and having avoided silica tube often to burn out influences the deacidification effect phenomenon, useful to the steady quality of thermal silica product.Therefore the utility model is that a kind of heating efficiency is higher, and silica tube is longer relatively work-ing life, and deacidification effect is better, and silica tube is changed more convenient, the thermal silica depickling stove that the hydrogenchloride condensation vapor is less.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to schematic top plan view.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Embodiment
As Fig. 1, a kind of thermal silica depickling stove 1 shown in Figure 2, comprise steam input section 2, heating zone 3 and expansion segregation section 4, steam input section 2 is provided with superheated vapour inlet 21, the bottom of heating zone 3 is provided with thermal silica inlet 31, heating zone 3 laterally is provided with 10 groups of U type silica tubes 5, enlarge segregation section 4 and be provided with thermal silica outlet 41, acid vapor outlet 42, equipment support 43 and observation visor 44, enlarge segregation section 4 and vertically also be provided with U type silica tube 5, the termination 51 of U type silica tube 5 is tightly connected by the furnace wall 11 of flange 6 with depickling stove 1, and the power supply mode of connection of this U type silica tube 5 connects for the 220V constant voltage.
Above-mentionedly enlarging the U type silica tube 5 that segregation section 4 is vertically established, can be 3,4,6,8,10 etc. according to the actual needs of depickling stove 1, depickling stove commonly used at present is better with 6 U type silica tubes.
