Description
Technical field
The utility model relates to nitric acid production auxiliary process equipment technology fields, particularly relate to a kind of deaerating type of cycles.
Background technique
Currently, needing to use ammonia alcohol as raw material in nitric acid production technique, making in most nitric acid chemical companies
In the technical process of standby ammonia alcohol, need to carry out it by deaerating type of cycles deoxygenation processing, existing deoxygenation processing system is generally wrapped
It includes except desalted water is sent within oxygen-eliminating device by oxygen, cold desalination pipe and steam pipe, cold desalination pipe, steam is sent by steam pipe simultaneously
Within oxygen-eliminating device, but this kind of deoxygenation processing system, when used for a long time, desalted water and steam consumption are very big, and steam enters
It can not be recycled after oxygen-eliminating device, some vapor can also be mixed with production product, cause to be mingled in the product produced
A large amount of moisture influences the quality for producing product.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of deaerating type of cycles.
The utility model is achieved by the following technical programs.
The utility model provides a kind of deaerating type of cycles, mainly includes oxygen-eliminating device, cold desalination pipe, steam pipe and Steam Recovery
Desalted water is accessed in pipe, one end of the cold desalination pipe, and steam, the other end of the cold desalination pipe are accessed in one end of the steam pipe
It is accessed after being connected in parallel with the other end of the steam pipe at the top of the oxygen-eliminating device, the oxygen-eliminating device bottom is connected with outlet
Pipe, the oxygen-eliminating device bottom is also connected to by the steam recovery pipe with the steam pipe.
The cold desalination pipe outside diameter is φ 133mm.
The steam pipe outside diameter is φ 32mm.
The Steam Recovery pipe outside diameter is identical as the steam pipe outside diameter.
Flow control valve is also equipped on the cold desalination pipe.
Filter plate is additionally provided within the cold desalination pipe, filter plate is set to the cold desalination pipe and the steam pipe connects
Before meeting place.
The utility model has the beneficial effects that: being carried out at deoxygenation using the technical solution of the utility model to ammonia alcohol
When reason, can by steam recovery pipe to be sent into oxygen-eliminating device within steam be recycled, thus improve simultaneously steam and
The utilization efficiency of desalted water saves resource, and effectively prevents being mingled with moisture in ammonia alcohol, ensure that product quality, in addition,
It is additionally provided with filter plate within cold desalination pipe, filters out the other materials in desalted water, ensure that being normally carried out for deoxygenation reaction.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1- oxygen-eliminating device, the cold desalination pipe of 2-, 3- steam pipe, 4- steam recovery pipe, 5- outlet, 6- flow control valve,
7- filter plate.
Specific embodiment
Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.
As shown in Figure 1, the utility model provides a kind of deaerating type of cycles, including oxygen-eliminating device 1, cold desalination pipe 2, steam pipe 3
With steam recovery pipe 4, desalted water is accessed in one end of cold desalination pipe 2, and steam is accessed in one end of steam pipe 3, cold desalination pipe 2 it is another
1 top of access oxygen-eliminating device after the other end of end and steam pipe 3 is connected in parallel, 1 bottom of oxygen-eliminating device is connected with outlet 5, deoxygenation
1 bottom of device also passes through steam recovery pipe 4 and is connected to steam pipe 3.
It, can be by steam recovery pipe to sending when carrying out deoxygenation processing to ammonia alcohol using the technical solution of the utility model
Enter the steam within oxygen-eliminating device to be recycled, to improve the utilization efficiency of steam and desalted water simultaneously, saves money
Source, and effectively prevent being mingled with moisture in ammonia alcohol, it ensure that product quality, in addition, being additionally provided with filtering within cold desalination pipe
Plate filters out the other materials in desalted water, ensure that being normally carried out for deoxygenation reaction.
Further, it is preferable to which cold 2 outer diameter of desalination pipe is φ 133mm.3 outer diameter of steam pipe is φ 32mm.Outside steam recovery pipe 4
Diameter is identical as 3 outer diameter of steam pipe.
In addition, being also equipped with flow control valve 6 on cold desalination pipe 2.It can desalted water input flow rate by flow control valve 6
The effect of being controlled, reaching saving resource, improve desalination water application efficiency.
Further, it is preferable to be additionally provided with filter plate 7 within cold desalination pipe 2, filter plate 7 is set to cold desalination pipe 2 and steams
Before 3 junction of steam pipe.Other impurity in desalted water are filtered out by filter plate 7, ensure that being normally carried out for deoxygenation reaction,
It ensure that the oxygen removal efficiency and quality of ammonia alcohol.
