Abstract
A kind of silanes tail gas absorber for avoiding tail gas admission line from blocking, belongs to the tail gas treatment device technical field of Chemical Manufacture, for avoiding silanes tail gas absorber admission line from blocking.Its technical solution is：Tail gas admission line is mounted at the top of tower body, and nozzle is mounted in tower body, and shower water pipeline is connected with nozzle, and nitrogen purge pipe is located at outside tower body, and the gas outlet of nitrogen purge pipe is connected on the tail gas admission line at the top of tower body.The nitrogen of the utility model enters absorption tower from top to bottom from tail gas from absorption tower entrance, the nitrogen being blown into both can guarantee that tail gas was not detained in the entrance of tail gas from absorption tower admission line, it can prevent the water mist of shower water from returning at the inlet exhaust gas of tail gas absorber again, it effectively prevents the fluorosilane-type materials in tail gas and reacts generation silica with steam in tail gas from absorption tower admission line, it also avoids silica to be deposited in the admission line of absorption tower, thoroughly solves the problems, such as the blocking of tail gas admission line.
Description
Technical field
The utility model is related to a kind of chemical industry absorption towers that silanes tail gas absorber admission line can be avoided to block, and belong to
In the tail gas treatment device technical field of Chemical Manufacture.
Background technology
Tail gas absorber is widely used in chemical production field, and tail gas absorber is the capital equipment of various vent gas treatments,
Very important effect is played in Chemical Manufacture.Existing tail gas absorber often goes out since there are certain defects for design
The case where being blocked at existing inlet exhaust gas, in order to ensure device for absorbing tail gas normal operation, it is necessary to often to inlet exhaust gas pipeline into
Row cleaning.
Tail gas absorber used at present include tower body, the tail gas admission line of top of tower, the elution nozzle installed in tower,
The nitrogen purge pipe configured at the top of absorbing tower.The tail gas absorber of this structure can handle the tail gas of certain flow, but work as
Tail is narrow-minded, when flow velocity is low, water mist that elution nozzle generates can on return to the entrance of tail gas absorber tail gas admission line, though
It is furnished with nitrogen purge pipe at the top of right absorption tower, but the position of nitrogen purge pipe is relatively on the lower, purging nitrogen can not prevent water
The rising of mist, therefore water mist still can rise at the inlet exhaust gas of tail gas absorber.
Due to there is a large amount of fluorosilane-type materials in pending tail gas, and fluorosilane-type materials can generate titanium dioxide after meeting water
Silicon, the silica of generation have small part and are attached on the entrance tube wall of admission line, over time, increasingly
More silica is deposited in the admission line of absorption tower, finally blocks tail gas admission line completely.For that purpose it is necessary to often right
Inlet exhaust gas pipeline is cleared up, this not only increases the workload of maintenance work, is also affected production and is normally carried out, therefore ten
Point it is necessary to be improved to existing tail gas absorber.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of silanes tails for avoiding tail gas admission line from blocking
Aspiration tower, this absorption tower be less prone to tail gas admission line block the case where, can keep vent gas treatment it is steady into
Row.
Solving the technical solution of above-mentioned technical problem is：
A kind of silanes tail gas absorber for avoiding tail gas admission line from blocking, it includes tower body, tail gas admission line, spray
Water drenching pipeline, nozzle, nitrogen purge pipe, tail gas admission line are mounted at the top of tower body, and nozzle is mounted in tower body, shower water
Pipeline is connected with nozzle, and improvements are that nitrogen purge pipe is located at outside tower body, and the gas outlet of nitrogen purge pipe connects
It is connected on the tail gas admission line at the top of tower body.
The above-mentioned silanes tail gas absorber for avoiding tail gas admission line from blocking, the nozzle installed in the tower body from upper and
Lower multilayer is laid, nozzle number of the nozzle quantity topmost installed at the top of tower body less than the installation of in the middle part of tower body and tower body lower part
Amount.
The utility model has the beneficial effects that：
The former nitrogen pipeline being mounted at the top of absorption tower is changed on tail gas from absorption tower admission line by the utility model, nitrogen
Gas from tail gas from absorption tower entrance from top to bottom enter absorption tower, the nitrogen being blown into both can guarantee tail gas not tail gas from absorption tower into
The entrance of feed channel is detained, and can prevent the water mist of shower water from returning at the inlet exhaust gas of tail gas absorber, is effectively prevented
Fluorosilane-type materials in tail gas, which are reacted with steam in tail gas from absorption tower admission line, generates silica, also avoids dioxy
SiClx is deposited in the admission line of absorption tower.The utility model is simple in structure, works well, and thoroughly solves tail gas admission line
The problem of blocking, is made that contribution for the even running of vent gas treatment.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
It is marked in figure as follows：Tower body 1, nitrogen purge pipe 2, shower water pipeline 3, nozzle 4, tail gas admission line 5.
Specific implementation mode
The utility model includes：Absorption tower tower body 1, nitrogen purge pipe 2, shower water pipeline 3, nozzle 4, tail gas air inlet pipe
Road 5.
The utility model has adopted original absorption tower tower body 1, shower water pipeline 3, nozzle 4, tail gas from absorption tower admission line
5, on the original basis, improve the position of nitrogen blow valve port.
It is shown in figure, nitrogen purge pipe 2 is located at outside tower body 1, and the gas outlet of nitrogen purge pipe 2 is connected to tower body 1
On the tail gas admission line 5 at top, nitrogen enters from tail gas admission line 5 in absorption tower together in company with tail gas.The nitrogen being blown into
Not only it can guarantee that tail gas was not detained in the entrance of tail gas from absorption tower admission line 5, but also can prevent the water mist of shower water from returning to tail gas
At the inlet exhaust gas on absorption tower, fluorosilane-type materials in tail gas are effectively prevented in tail gas from absorption tower admission line 5 and water
Vapour reaction generates silica, also avoids silica and is deposited in absorption tower admission line 5.
It is shown in figure, the nozzle 4 installed in tower body 1 from top to bottom lay by multilayer, is topmost installed close to 1 top of tower body
Nozzle 4 quantity of 4 quantity of nozzle less than tower body 1 middle part and the installation of 1 lower part of tower body.It can be reduced in this way close to 1 top of tower body
Steam reduces the quantity reacted with steam in 1 top fluorosilane-type materials of tower body and generate silica, silica is avoided to absorb
Accumulation in tower admission line 5.
The course of work of the utility model is as follows：
Silanes tail gas enters absorption tower tower body 1 from tail gas from absorption tower admission line 5, while purging nitrogen and being purged from nitrogen
Pipeline 2 enters absorption tower tower body 1, and silanes tail gas is in absorption tower tower body 1 with the washing water of shower water pipeline 3 in nozzle 4
Spray effect under react, achieve the purpose that tail gas absorption.
The utility model can prevent the water mist of shower water return to tail gas absorber tail gas admission line 5 entrance, have
Preventing tail gas admission line 5 to effect, there is a situation where block.
