This device will give up the denitration catalyst and through the processing of breaker and reducing mechanism, can be used multipurposely desired suitable, even particle diameter, the import of dust collection device is put through with breaker, reducing mechanism respectively, and the dust of fragmentation process and crushing process production can fully be retrieved in export and feed bin import switch -on, and the operation in -process can not produce secondary pollution, reduces the influence to the environment, improves the utilization efficiency of resource.
Description
Technical field
This utility model relates to a kind of useless denitrating catalyst recycling and processing device, the pretreatment unit of a kind of useless denitrating catalyst.
Background technology
SCR method catalyst is with TiO2For carrier, it is mainly composed of V2O5-WO3(MoO3) etc. metal-oxide, these compositions account for more than the 90% of catalyst total amount, and the concrete coal that remaining microcomponent uses according to boiler is added.SCR denitration generally uses the mounting means of " 2+1 ", the most first installs 2 layers of catalyst, installs the 3rd layer after about 3 years again additional, changes the 1st layer of catalyst, within the most every 2 years, change one layer of catalyst after 3 years.
How a large amount of dead catalyst lost efficacy process, dispose the great attention having caused countries in the world.Carry out spent catalyst recovery and utilizing both can turn waste into wealth, change evil for benefit, it is also possible to solve corresponding a series of potential problem of environmental pollution, thus bring considerable economic benefit and social benefit.
The most useless denitrating catalyst reclaims comprehensive utilizating research and is concentrated mainly on Technology, and the pretreatment unit research producing industrialization is less.The useless denitrating catalyst reclaimed materials preparation facilities that patent CN204429424U proposes, mainly include transfer assembly, reducing mechanism and discharge component, it is not directed to the dust collecting that crushing process produces, easily in crushing process, cause secondary environmental pollution, the denitrating catalyst that simultaneously gives up is directly entered reducing mechanism, easily cause the abrasion to reducing mechanism, increase reducing mechanism processing pressure, it is also difficult to reach the subsequent request of useless denitrating catalyst comprehensive utilization.
Summary of the invention
The purpose of this utility model is to provide one useless denitrating catalyst pretreatment unit, avoids producing in running secondary pollution simultaneously, provides the raw material of appropriate particle size for follow-up comprehensive utilization of reclaiming.
For solving the problems referred to above, the technical solution adopted in the utility model is:
A kind of useless denitrating catalyst pretreatment unit, including breaker, reducing mechanism, dust collecting and useless denitrating catalyst feed bin, described breaker, reducing mechanism are connected by the conveyer belt of feeding successively with useless denitrating catalyst bin device；Described dust collecting is two, and the import of the two is connected by pipeline with breaker, reducing mechanism respectively, and outlet is connected by pipeline with described useless denitrating catalyst feed bin import respectively；Described useless denitrating catalyst is inputted described breaker by conveyer belt, and each device being sequentially sent to connect each other processes, described useless denitrating catalyst feed bin reclaim.
Described conveyer belt or pipeline are corrosion-resistant material material products.
Described breaker is jaw crusher or hammer mill, and the diameter of particle after crushing is less than 30mm.
Described reducing mechanism uses Raymond mill, and after mill, the particle diameter of powder body is less than 200 m.
Described dust collecting uses sack cleaner.
The beneficial effects of the utility model are: the useless denitrating catalyst process by breaker, can obtain adapting to the granule of the reasonable particle diameter that reducing mechanism processes, disperse and alleviate follow-up reducing mechanism processing pressure, reduce the abrasion to reducing mechanism；Dust collecting is connected with breaker, reducing mechanism respectively, can fully reclaim shattering process and the dust of crushing process generation, will not produce secondary pollution, reduce the impact on environment, improve the utilization ratio of resource in running；Useless denitrating catalyst after treatment, can meet the particle diameter suitable, uniform required by comprehensive utilization.
Accompanying drawing explanation
Fig. 1 is that this utility model gives up the structured flowchart of denitrating catalyst pretreatment unit.
Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present utility model is described in further detail.
As shown in Figure 1, this useless denitrating catalyst pretreatment unit, mainly include breaker 1,2, two dust collectings 3 of reducing mechanism and useless denitrating catalyst feed bin 4, breaker 1, reducing mechanism 2 and useless denitrating catalyst feed bin 4, gumming crushing device 2 is outer to be in turn switched on by the conveyer belt for feeding to each other；The import of two dust collectings 3 is connected by pipeline with breaker 1, reducing mechanism 2 respectively, and the import that two dust collectings 3 export with feed bin 4 is connected by pipeline.
Conveyer belt or pipe material are resistant material.
Breaker 1 is jaw crusher or hammer mill, and the diameter of particle after crushing is connected less than the charging aperture of 30mm, the discharging opening of breaker 1 and reducing mechanism 2.
Reducing mechanism 2 is Raymond mill, and after mill, the particle diameter of powder body is less than 200 m, and the discharging opening of reducing mechanism 2 is connected with useless denitrating catalyst feed bin 4.
Dust collecting 3 uses sack cleaner.
When this utility model runs, first useless denitrating catalyst is entered breaker 1 through conveyer belt, it is broken for meeting the powder body that reducing mechanism 2 requires by useless denitrating catalyst, then powder body entrance reducing mechanism 2 is pulverized further, being crushed to particle diameter and enter useless denitrating catalyst feed bin 4 less than 200 m, the dust of shattering process and crushing process generation enters useless denitrating catalyst feed bin 4 by dust collecting 3 after being collected.
The utility model has the advantage of:
(1) the useless denitrating catalyst process by breaker, can obtain adapting to the granule of the reasonable particle diameter that reducing mechanism processes, alleviate follow-up reducing mechanism processing pressure, reduce the abrasion to reducing mechanism；
(2) dust collecting is connected with breaker, reducing mechanism respectively, can fully reclaim shattering process and the dust of crushing process generation, running will not produce secondary pollution, reduce the impact on environment, improve utilization ratio social benefit and the obvious environment benefit of resource；
(3) useless denitrating catalyst after treatment, can meet the particle diameter suitable, uniform required by comprehensive utilization.
