Abstract
The invention discloses a preparation method for preparing white cement raw materials from waste catalysts. The method comprises the specific steps of intensively recovering the waste catalysts; drying the waste catalysts by a flash drying machine at 150-200 DEG C for 20-40 seconds; calcining the dried materials in a flash boiling calcining furnace at 650-700 DEG C for 1-2 minutes; cooling the calcined materials to the normal temperature; and grinding the cooled materials by a 300-mesh industrial grinding machine to obtain the white cement raw materials. According to the method, the performance of white cement can be improved and enhanced, and the problem of environmental pollution caused by waste catalyst burying can be solved; and meanwhile, the resource utilization rate is increased, the waste discharge is reduced, and the sustainable development is realized.
Description
Technical field
The present invention relates to the preparation method that a kind of dead catalyst secondary utilizes, be specifically related to a kind of production method utilizing dead catalyst to prepare white cement raw material.
Background technology
The annual working ability of China's catalytic cracking is more than 1.5 hundred million tons, and annual spent catalyst amounts is 1 × 105More than t.Along with the rising year by year of crude runs, the demand of catalyst is continuously increased.Catalyst in use, because being lost activity by impacts such as high temperature, poisonous substance, coking, mechanical wears, becomes dead catalyst.At present, domestic most by the method for burying to existing dead catalyst, i.e. by digging pit, dead catalyst is imbedded in deep soil.This method, although can exempt from temporarily to solve the process problem of dead catalyst, but there is the shortcoming polluted environment, ruin soil property, largely effect on the resource that the mankind depend on for existence.And the main component of Cracking catalyst is SiO2And Al2O3, accounting for more than 90%, other component ratio is little；White cement is mainly made up of chiltern mineral, the ratio that silicon, aluminum, calcium oxide account for is the biggest, more and more big because of the relatively strong usage amount in building industry of its dicoration due to white cement again, the raw material preparing white cement is consequently increased, thus needs to spend a large amount of natural resources.
Summary of the invention
Present invention aim at providing a kind of production method utilizing dead catalyst to prepare white cement raw material, the method is possible not only to improve the performances such as the intensity of white cement, whiteness, it is also possible to solves dead catalyst and buries the problem of environmental pollution brought；Improve the utilization rate of resource simultaneously, reduce the discharge of garbage, it is achieved sustainable development.
In order to achieve the above object, the present invention utilizes dead catalyst to prepare the production method of white cement raw material, specifically includes following steps:
A by after dead catalyst centralized recovery, is first 150-200 DEG C of dry 20-40S with flash dryer in temperature, and dried material enters flicker fluidized-bed kiln, calcines 1-2min at 650-700 DEG C,
The incinerated matter that a is walked by b industrial grinding mills grinds to 300 mesh, obtains this white cement raw material.
Described dead catalyst is the FCC catalyst produced in petroleum chemical enterprise's catalytic cracking production process.
In technique scheme, by utilizing the dead catalyst produced in Effect of Catalysis In Petrochemistry cracking production process, the purpose using calcining is the carbon deposit on burning-off dead catalyst, recovers internal pore volume；It is ground with the industrial grinding mills in 300 mesh sieve holes so that it is there is specific particle diameter, plays effect white cement being strengthened, brightening.
The present invention compared with prior art, has the advantage that
(1) present invention is possible not only to solve dead catalyst and buries the problem of environmental pollution brought, it is also possible to is recycled as secondary resource, improves the utilization rate of resource, reduces the discharge of garbage, it is achieved sustainable development.
(2) dead catalyst recycling, decreases amount of landfill, has namely saved the land resource of preciousness；
(3) present invention is effectively improved and strengthens the performance that white cement brightens, and is greatly saved production cost.
Detailed description of the invention
The production method utilizing dead catalyst to prepare white cement raw material the present invention below in conjunction with specific embodiment is described further；
Embodiment 1
Fetching the dead catalyst 1000 kilograms of receipts, be first 150 DEG C of dry 20S with flash dryer in temperature, dried material enters flicker fluidized-bed kiln, 1min is calcined at 650 DEG C, after being cooled to room temperature, grind with the industrial grinding mills in 300 mesh sieve holes, obtain this white cement raw material.
Embodiment 2
Fetching the dead catalyst 1000 kilograms of receipts, be first 160 DEG C of dry 30S with flash dryer in temperature, dried material enters flicker fluidized-bed kiln, 1min is calcined at 680 DEG C, after being cooled to room temperature, grind with the industrial grinding mills in 300 mesh sieve holes, obtain this white cement raw material.
Embodiment 3
Fetching the dead catalyst 1000 kilograms of receipts, be first 180 DEG C of dry 35S with flash dryer in temperature, dried material enters flicker fluidized-bed kiln, 2min is calcined at 690 DEG C, after being cooled to room temperature, grind with the industrial grinding mills in 300 mesh sieve holes, obtain this white cement raw material.
Embodiment 4
Fetching the dead catalyst 1000 kilograms of receipts, be first 200 DEG C of dry 40S with flash dryer in temperature, dried material enters flicker fluidized-bed kiln, 2min is calcined at 700 DEG C, after being cooled to room temperature, grind with the industrial grinding mills in 300 mesh sieve holes, obtain this white cement raw material.
When producing white cement, take cement raw material 5 10% of the present invention and be added in other raw material.After testing, the present invention white cement raw material prepared, it is substantially improved and strengthens the performance such as whiteness of white cement, on the one hand, replace part former use limestone as raw material, save natural resources；On the other hand, it is also possible to solve dead catalyst and bury the problem of environmental pollution brought；Improve the utilization rate of resource simultaneously, reduce the discharge of garbage, it is achieved sustainable development.
Claims (2)
1. one kind utilizes the production method that dead catalyst prepares white cement raw material, it is characterised in that: specifically include following steps:
A is by after dead catalyst centralized recovery, and first using flash dryer is 150-200 DEG C of dry 20-40S in temperature, and dried material enters flicker fluidized-bed kiln, calcines 1-2min at 650-700 DEG C, is cooled to room temperature, obtains incinerated matter；
