Description
Technical field
The present invention relates to dithiocarbonic anhydride Reaktionsofen, be specifically related to a kind of dithiocarbonic anhydride Reaktionsofen of type material.
Background technology
In current Chemical Manufacture, the production Reaktionsofen of dithiocarbonic anhydride is inside and outside two-layer, and void layer is left in centre.Inner furnace body is metal body of heater, and outer wall is built into refractory brick.There is a lot of shortcoming in this structure:
1 does not directly suffer heat (1300-1400 degree) to make internal protecting wall, at the fire-resistant brick protective layer of inner furnace body external application.Again in order to avoid inner furnace body expands with heat and contract with cold the cracking and slump causing refractory masses, void layer has been stayed in centre.This structure makes heat transfer performance greatly reduce, and adds heat energy loss, improves production cost.Again in order to protect inner furnace body, in order to avoid fast heating causes body of heater to be out of shape when new stove first time puts into production, body of heater heats up generally needs 20-25 days, greatly reduces production efficiency.
2 due to inner furnace body be that metallic substance is made, in use in-furnace temperature is at about 900 degree, add high density active sulphur again and carry out chemical reaction, make that metal internal protecting wall is as easy as rolling off a log suffers that sulfuration is encroached on, also oxidative attack is suffered in the hot environment of outer furnace wall for a long time more than 1000 degree, thus metal inner furnace body about 12 months mean life under inside and outside pincer attack, often change a body of heater, the moon two consuming time wheat harvesting period, causing can not continuous seepage, greatly reduce production efficiency, improve production cost.
3 due to inner furnace body be metal material, and to be in for a long time in hot environment, the sulfuration of stove inwall and outer wall oxidation, to cause metal body of heater that inside and outside different materials change occurs, can not cease fire.If ceased fire in actual production because inside and outside coefficient of expansion difference causes body of heater to burst.
Chinese patent 92112153.9 discloses one " carbon sulfide reaction retort " this patent to overcome metal inner furnace body corrosion design.Reaction rice steamer amorphous refractory high alumina castable or phosphoric acid salt add refractory fibre pouring in conjunction with mould material and form, and external coating has high-temperature resistant coating.The weak point of this design is that the large-scale housing of refractory material casting at high temperature very easily cracks, and causes body of heater to cave in, is thus difficult to carry out in practice, practical application useless.
Chinese patent 03112067.9 " dithiocarbonic anhydride Reaktionsofen " illustrates silica brick and high alumina brick.Silica brick belongs to acid material; ore deposit phase composite is mainly phosphorus quartz, cristobalite and remaining quartz; its goods are when 200 ~ 300 DEG C and 573 DEG C, and due to crystal conversion, volume expands suddenly; and use brick body of heater to have relatively many brickwork joints; usual chamotte all can not be sintered at 900 DEG C, when chamotte could not fully sintered brick body expansion suddenly, brickwork joint is easy to produce crack; cause furnace sealing not tight, can not use.In this, as the building materials of body of heater, use the crackle of middle generation that body of heater can be made to leak gas, serious meeting makes body of heater directly scrap, and has a strong impact on the life-span of body of heater.
High alumina brick take corundum as the fire resistive material product of principal crystalline phase.Its chemical stability is better, but corrosion resistance is very weak, uses middle material to be progressively etched, causes converter life shorter.Thermal shock resistance is slightly good relative to silica brick, but still existence is expanded, shunk the body of heater gas leakage caused, and can not meet the long-life requirement of body of heater equally.
Summary of the invention
The present invention is directed to problems of the prior art, a kind of dithiocarbonic anhydride Reaktionsofen of type material is provided.
Technical scheme of the present invention is:
A kind of dithiocarbonic anhydride Reaktionsofen of type material, comprise body of heater, body of heater is divided in the middle part of upper of furnace body, body of heater and lower portion of furnace body, upper of furnace body is provided with carburizing hole and carbon disulfide gas outlet, lower portion of furnace body is provided with except cinder notch and adds sulphur mouth, described body of heater by refractory materials silicon nitride combined silicon carbide pour into a mould form, upper of furnace body with in the middle part of body of heater between, in the middle part of body of heater with between lower portion of furnace body with refractory mortar bonding.
Concrete, described the lid fired by metal or pyroceramic is set except cinder notch, carburizing hole place.
Advantage of the present invention is: the body of heater of 1 dithiocarbonic anhydride Reaktionsofen provided by the invention adopts silicon carbide to make in conjunction with silicon nitride material, the outer wall that cancellation refractory brick is built into and void layer, direct heating body of heater itself, silicon nitride products based on silicon carbide thermal conductivity is high, thermal conductivity is 7 ~ 8 times of common refractory, substantially improves heat transfer property, reduces the loss of heat energy, the energy about 20% can be saved, and substantially increase the work-ing life of equipment; 2 silicon nitride combined silicon carbide materials have well corrosion-resistant, anti-oxidant, avoid sulfuration and oxidizing reaction improves work-ing life, improve production efficiency, have saved cost; The dithiocarbonic anhydride Reaktionsofen of 3 silicon nitride combined silicon carbide materials, quality is hard, and Mohs' hardness is about 9, normal temperature strength is high, under 1200-1400 DEG C of high temperature, almost keep the intensity identical with normal temperature and hardness, thermal expansivity is little, not easily produce thermal stresses, there is good thermal shock resistance, because having these characteristics, can being rapidly heated to optimal reaction temperature when heating, reduce energy consumption, enhance productivity; 4 due to silicon nitride products based on silicon carbide thermal expansivity little (being the half of high alumina refractory) with have good thermal shock resistance, so the Reaktionsofen adopting this material to make can heat cooling repeatedly, body of heater is indeformable not to ftracture, and makes production have more handiness.
