Description
Technical field
The invention belongs to environmental technology fields, are related to a kind of denitrating catalyst performance monitoring device.
Background technique
Current overwhelming majority unit all uses SCR flue gas denitrification system, and catalyst is the key component of SCR denitration, by more
The influence of kind factor, catalyst is using after a certain period of time, in fact it could happen that the problems such as being poisoned, staiing leads to catalyst inactivation, makes to urge
The denitration performance of agent declines, and so as to cause the increase of denitrating system the escaping of ammonia rate, influences unit safety in operation.Due to catalyst
Performance can not on-line checking, part integral catalyzer is generally replaced using catalyst batten, when denitrating system occur it is abnormal
When state, or periodically, during compressor emergency shutdown, extraction section batten is detected, to judge whether catalyst performance is normal.This
Kind monitoring means is often limited by the operating status of unit, and also needs in cold state, and workload is extracted in the placement of batten
It is larger, therefore the flexibility of catalyst performance monitoring is insufficient.
Summary of the invention
To solve the problems, such as involved in background, the present invention provides a kind of denitrating catalyst performance monitoring devices.
The technical solution adopted by the present invention to solve the technical problems is:
The present invention includes smoke deflector, water conservancy diversion plate bracing frame, catalyst guide rail, mounting bracket, catalyst sample.
The smoke deflector, for partial fume to be inducted into catalyst sample, the purpose is to avoid catalyst sample
When being originally placed in air velocity distribution, because catalyst sample resistance leads to flow through the flue gas flow rate in catalyst sample lower than normally urging
Flow velocity in agent.Smoke deflector is fabricated to obtuse angle structure using stainless steel plate, and two panels smoke deflector is arranged symmetrically, and is formed
The cavity of one placement catalyst sample applies example: cavity width 140mm, length 1000mm, height with of the invention one
200mm is spent, the catalyst sample of 6~8 pieces of side length 120mm cubes can be disposably placed.It needs in different application according to catalyst
The size and number of sample determine.
The water conservancy diversion plate bracing frame prevents smoke deflector from deforming for fixing smoke deflector structure.
The catalyst guide rail is made of stainless steel angle steel, extends to position deep enough inside SCR denitration reaction device
It sets, cooperates with smoke deflector, for the support platform as catalyst sample.Smoke deflector is welded deep in catalyst guide rail
Enter one end inside SCR denitration reaction device.
The mounting bracket, for catalyst guide rail to be fixedly installed in inside SCR denitration reaction device, specific structure with
Size needs to be determined according to specific SCR denitration reaction device internal structure, as long as being capable of fixing catalyst guide rail and meeting its stability
Intensity.
The catalyst sample, as monitor sample, apply example with of the invention one: catalyst sample is fabricated to
The cube of side length 120mm.
Apparatus of the present invention are installed in the cavity of SCR denitration reaction device, are located at manhole door lower part, are operated normally in unit
Cheng Zhong can temporarily open manhole door, be placed or taken out catalyst sample.It, can be on catalyst sample for the ease of high-temperature operation
A handle is made with steel wire, the shank of a sufficient length is in addition made again, hooks handle with shank, it can be safely and conveniently
It is placed or taken out catalyst sample.
The present invention has the beneficial effect that:
The object of the invention is to be placed at any time during normal operation in unit, extract catalyst sample, improve
The flexibility and real-time of catalyst performance monitoring.
Detailed description of the invention
Fig. 1 is principle schematic diagram of the invention.
In Fig. 1: 1, smoke deflector, 2, water conservancy diversion plate bracing frame, 3, catalyst guide rail, 4, mounting bracket, 5, catalyst sample
This.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
As shown in Figure 1, a kind of denitrating catalyst performance monitoring device, including smoke deflector 1, water conservancy diversion plate bracing frame 2, urge
Agent guide rail 3, mounting bracket 4, catalyst sample 5.
The smoke deflector 1, for partial fume to be inducted into catalyst sample 5, the purpose is to avoid catalyst
When sample 5 is placed in air velocity distribution, it is lower than because 5 resistance of catalyst sample causes to flow through the flue gas flow rate in catalyst sample 5
Flow velocity in normal catalytic agent.Smoke deflector 1 is fabricated to obtuse angle structure using stainless steel plate, and two panels smoke deflector 1 is symmetrical
Arrangement, forms the cavity of a placement catalyst sample 5, applies example: cavity width 140mm, length with of the invention one
1000mm, height 200mm are spent, the catalyst sample 5 of 6~8 pieces of side length 120mm cubes can be disposably placed.In different application
It need to be determined according to the size and number of catalyst sample 5.
The water conservancy diversion plate bracing frame 2 prevents smoke deflector 1 from deforming for fixing 1 structure of smoke deflector.
The catalyst guide rail 3 is made of stainless steel angle steel, extends to enough depths inside SCR denitration reaction device
Position cooperates with smoke deflector 1, for the support platform as catalyst sample 5.Smoke deflector 1 is welded in catalyst
Guide rail 3 gos deep into one end inside SCR denitration reaction device.
The mounting bracket 4, for catalyst guide rail 3 to be fixedly installed in inside SCR denitration reaction device, specific structure
It needs to be determined according to specific SCR denitration reaction device internal structure with size, as long as being capable of fixing catalyst guide rail 3 and meeting its stabilization
Property intensity.
The catalyst sample 5, as monitor sample, apply example with of the invention one: catalyst sample 5 makes
At the cube of side length 120mm.
Apparatus of the present invention are installed in the cavity of SCR denitration reaction device, are located at manhole door lower part, are operated normally in unit
Cheng Zhong can temporarily open manhole door, be placed or taken out catalyst sample 5.It, can be in catalyst sample 5 for the ease of high-temperature operation
On with steel wire make a handle, in addition make the shank of a sufficient length again, hook handle with shank, can safe ready
Ground is placed or taken out catalyst sample 5.
