Abstract
The utility model provides a broken reducing mechanism of useless denitration catalyst, including breaker, reducing mechanism and useless denitration catalyst feed bin, each device is put through by the conveyer belt that is used for the pay -off each other in proper order, breaker is inputed by the conveyer belt to useless denitration catalyst to send into each device of putting through each other in proper order and handle, retrieve by useless denitration catalyst feed bin. The utility model discloses to give up the denitration catalyst through breaker's processing, can be adapted to the granule of the reasonable particle diameter that the reducing mechanism handled, and alleviate the reducing mechanism and handle pressure, reduce the wearing and tearing to the reducing mechanism, useless denitration catalyst behind shredding can satisfy and use multipurposely desired suitable, even particle diameter.
Description
Technical field
This utility model relates to a kind of useless denitrating catalyst recycling and processing device, the broken reducing mechanism 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 broken apart device that patent CN203764363U proposes is mainly for waste and old plate-type denitration catalyst, and broken apart device is only disintegrating machine, is extremely difficult to the follow-up Particle size requirements of useless denitrating catalyst comprehensive utilization.
Summary of the invention
The purpose of this utility model is to provide the useless denitrating catalyst of one to crush reducing mechanism, 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 crushes reducing mechanism, and including breaker, reducing mechanism and useless denitrating catalyst feed bin, described each device is in turn switched on by the conveyer belt for feeding to each other；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 is 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 is Raymond mill, and after mill, the particle diameter of powder body is less than 200 m.
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, alleviate follow-up reducing mechanism processing pressure, reduce the abrasion to reducing mechanism；Useless denitrating catalyst after size-reduced process, can meet suitable, the uniform grading required by comprehensive utilization.
Accompanying drawing explanation
Fig. 1 is that this utility model denitrating catalyst that gives up crushes the structured flowchart of reducing mechanism.
Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present utility model is described in further detail.
As it is shown in figure 1, this useless denitrating catalyst crushes reducing mechanism, mainly including breaker 1, reducing mechanism 2 and useless denitrating catalyst feed bin 3, described each device is in turn switched on by for feeding and conveyer belt that material is resistant material to each other.
Breaker 1 is jaw crusher or hammer mill, and the diameter of particle after crushing is connected by the conveyer belt of feeding less than the charging aperture of 30mm, the discharging opening of breaker 1 and reducing mechanism 2.
Reducing mechanism 2 uses 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 3.
When this utility model runs, first through conveyer belt, useless denitrating catalyst being sent into breaker 1, useless denitrating catalyst is broken for meeting the powder body that reducing mechanism 2 requires, then powder body entrance reducing mechanism 2 is pulverized further, it is crushed to particle diameter and is less than 200 m, enter useless denitrating catalyst feed bin 3 and reclaim.
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 reducing mechanism processing pressure, reduce the abrasion to reducing mechanism.
(2) subsequent treatment and final application for useless denitrating catalyst provide particle diameter suitable, uniform.
Claims (4)
1. a useless denitrating catalyst crushes reducing mechanism, it is characterised in that: it includes breaker, reducing mechanism and useless denitrating catalyst feed bin, and described each device is in turn switched on by the conveyer belt for feeding to each other；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.
