With the further severization of environmental requirement, it is active response《Implement in full coal-burning power plant's minimum discharge and energy-conservation changes
Make programme of work》Policy, coal unit has been gradually completing minimum discharge transformation.For less than 50mg/Nm3Nitrogen oxides super
Low emission requires, and increasing coal-burning power plant increases the consumption of denitrating catalyst, but the height in the face of domestic thermal power plant
For dustiness, the abrasion strength resistance performance of denitrating catalyst then becomes the important performance assessment criteria of the live running environment of reply.
At present, for the tear strength test device of SCR denitration, mainly there are comparative sample storehouse and test sample storehouse
Series connection and two kinds of tear strength test modes being arranged in parallel, it is each only capable of series connection test result and in parallel test are implemented separately
As a result, the contrast wanting to realize two kinds of test results then need to be tested on two covering devices, needs two sets of test devices, investment
Larger.Thus research and develop a kind of catalyst abrasion strength test dress of arrangement combining using sample bin series and parallel
Put not only overall investment little, and series and parallel test can be carried out simultaneously, realize the rapid comparison of test result, improve test accurately
Degree.
Utility model content
The purpose of this utility model is the two kinds of tear strengths connected and be arranged in parallel with test storehouse for current sample bin
Test mode is only capable of series and parallel test is implemented separately, and its test mode is single to be compareed it is impossible to quickly realize test result, two sets
The problems such as test device investment is high and propose, the denitrating catalyst tear strength test device that a kind of connection in series-parallel is closed is provided.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is：

It is connected by airduct with the import of regulating valve；The outlet of described regulating valve is connected by airduct with the top entry of blender；Institute
The bottom two stating blender is exported and is connected by airduct with the import of two air volume meters respectively；The outlet of described two air volume meters divides
It is not connected by airduct with the import in two contrast storehouses；Airduct is passed through in one of outlet in contrast storehouse and the import of Venturi tube
Connect, the outlet in another contrast storehouse is connected by airduct with wherein any one import in dust arrester upper lateral part two import
Connect；The outlet of described Venturi tube is connected by airduct with the import in test storehouse；The outlet at bottom of described feed hopper and venturi
The throat of pipe passes through flange or is welded and fixed and connects and communicate；The outlet in described test storehouse and abrasion agent collection device upper lateral part
Import is connected by airduct；Another in outlet at bottom and dust arrester upper lateral part two import of described abrasion agent collection device
Import is connected by airduct.
Compared with prior art, this utility model has the advantage that：
The arrangement that a whole set of test device is combined with contrast storehouse series, parallel using test storehouse, can be urged simultaneously
The series connection of agent tear strength and test in parallel, realize the rapid comparison of two kinds of test mode test results of series and parallel, improve and survey
The accuracy of amount.
