Technical field
The present invention relates to a kind of vertical roasting stove that is used to contain solid particulate matter roasting under hot conditions of Korrosionsmedium.Refer in particular to a kind of vertical roasting stove that is used for the catalyst calcination process.
Background technology
At present, high-temperature roasting is the critical process in the oil refining catalyst preparation process.It directly influences the various physical and chemical performances of catalyst.But because sintering temperature height (about 500 ℃-650 ℃) contains certain Korrosionsmedium (as chlorion, water vapour etc.) again, so very high to the requirement of roaster in the catalyst.Mainly there is following problem in existing oil refining catalyst vertical roasting stove:
(1) main material of roaster is a stainless steel, and it is corrosion easily in high temperature and Korrosionsmedium, and directly pollutes the catalyst that roaster includes noble metal, thereby forms waste product, and economic loss is serious.This mainly is that the turning is many because the roaster overall structure is unreasonable, and the macro-corrosion exhaust emissions that generates in the roasting process is not smooth.Simultaneously, the stove inner exhaust gas enters feeding warehouse easily, forms low-temperature space at this, causes water recovery, combines the back with chlorion and produces " dew point " corrosion at the feeding warehouse inwall.And along with a large amount of tail gas is played a reversed role, when opening the big lid of feeding warehouse and feed intake, tail gas fills the air, and environment is abominable, is not easy to operation.
(2) corrosion is damaged easily in high temperature and Korrosionsmedium for the metal parts of roaster, and particularly as the tail gas egress filtering device of critical component, only be 10 days average service time.So not only make the roaster maintenance frequent, the maintenance cost height, and also idle cost is big.
(3) at high temperature elongation is very big for the charging pipe of roaster, and original structure has retrained its distortion, makes parts deformation such as tremie pipe and tail gas fairlead serious, has influenced the serviceability of roaster.
Summary of the invention
The purpose of this utility model is improved at shortcoming that exists in the background technology and problem, provide a kind of can long-period stable operation in harsh conditions such as high temperature, Korrosionsmedium, and pollute the vertical roasting stove of problems such as easy breakage of parts and high temperature deformation owing to corrode the material that causes in the time of can solving the catalyst roasting.
The technical scheme that realizes the utility model purpose is such: the utility model is incubated the body of heater of cartridge clip by band and is located at the hot-wind inlet of body of heater bottom, discharging opening and charging aperture are formed the roast system, be characterized in that a side of body of heater is provided with the feed system of band cooling air port, opposite side and upper of furnace body are provided with exhaust treatment system, described feed system is made up of feeding warehouse and feed pipe again, wherein the feed pipe that is connected by with body of heater is established in the bottom of feeding warehouse, described exhaust treatment system is made up of the gentle material separating device of tail gas filter, wherein tail gas filter is located at the top of body of heater, and the gas material separating device is located at a side of body of heater.
The utility model has been avoided the generation of waste product in the roasting process, has improved the quality of product.Former roaster product percent of pass is about 98%, and novel roaster product percent of pass reaches 100%.Calculate if handle 200 tons of noble metal catalysts per year, can avoid about 400 kilograms of waste product the whole year, amount to about 320,000 yuan of the amount of money.Avoid about 20,000 yuan of cost of waste disposal simultaneously; The utility model has also improved the life cycle of roaster, has guaranteed that it stablely covers with excellent operation.The average shut-down (breakdown) mainteance cycle of former roaster is 10 days, about 1.4 ten thousand yuan of each recondition expense, and down period is about 18 hours.The average time between overhauls(TBO) of novel roaster is 120 days, saves about 140,000 yuan of recondition expense, avoids down period about 180 hours.
