Abstract
The invention aims at providing a pipeline blowing system. The pipeline blowing system adopts the technical scheme that the pipeline blowing system comprises a nitrogen making machine, an air compressor and a main pipeline, wherein the outlets of the nitrogen making machine and the air compressor are respectively communicated with the main pipeline; a main pipeline valve is arranged on the main pipeline; a plurality of branch pipelines are further arranged on the main pipeline; the branch pipelines are communicated with the main pipeline; by-pass valves, equipment and blowing pipelines are arranged on the branch pipelines; the branch pipelines are communicated with the equipment required to be subjected to blowing operation through the blowing pipelines; blowing switches are further arranged on the blowing pipelines. The pipeline blowing system has the benefits that the system can effectively solve the problems that the failure rate of the nitrogen making machine is high, nitrogen quality cannot be guaranteed, maintenance consumes plenty of time and labor, the production schedule is affected, and liquid nitrogen is frequently required to be purchased during maintenance, and the pressure of compressed air is greater than that of nitrogen, in terms of pressure, compressed air can completely replace nitrogen to be applied to blowing operation of equipment, and interactive use is basically realized.
Description
Technical field
The present invention relates to chemical technology field, particularly relate to a kind of pipeline purging system.
Background technology
At present, in the production process of chemical products, often need to carry out purging operation to pipeline, conventional method purges for adopting nitrogen.Nitrogen can play starvation to the such as equipment such as treating column, salt melting system and storage tank or carry out the effect of nitrogen envelope, but nitrogen making machine fault rate is high, nitrogen mass can not be guaranteed, and maintenance time and effort consuming, affect manufacturing schedule, often need to need outsourcing liquid nitrogen in maintenance process, virtually add extra cost.For solving the problem, JP sends a circuits purging system, according to the existing equipment of enterprise, is incorporated by air compressor machine among whole system, under the prerequisite not increasing significant cost, meets the needs of production.
Summary of the invention
The object of this invention is to provide a kind of pipeline purging system.
Technical scheme of the present invention is: a kind of pipeline purging system, by nitrogen making machine, air compressor machine and main line composition, described nitrogen making machine is communicated with main line respectively with the outlet of air compressor machine, the exit of described nitrogen making machine is provided with the nitrogen valve exported for controlling nitrogen, the exit of described air compressor machine is provided with the air door exported for controlling compressed air, described main line is provided with main line valve, described main line is also provided with some bye-passes, any described bye-pass is communicated with main line, any described bye-pass is provided with branch road valve, equipment and scavenging pipeline, any described bye-pass is communicated with needing the equipment carrying out purging operation by scavenging pipeline, described scavenging pipeline is also provided with purging switch.
Beneficial effect of the present invention is: it is high that this system can effectively solve nitrogen making machine fault rate, nitrogen mass can not be guaranteed, maintenance time and effort consuming, affect manufacturing schedule, often need in maintenance process, need outsourcing liquid nitrogen problem, and compressed air pressure is greater than nitrogen pressure, nitrogen can be substituted completely for the purging operation to equipment from pressure, substantially accomplish mutual use.

Detailed description of the invention
Below in conjunction with accompanying drawing, brief description is made to the specific embodiment of the present invention.
A kind of pipeline purging system as shown in Figure 1, by nitrogen making machine 1, air compressor machine 2 and main line 3 form, described nitrogen making machine 1 is communicated with main line 3 respectively with the outlet of air compressor machine 2, the exit of described nitrogen making machine 1 is provided with the nitrogen valve 11 exported for controlling nitrogen, the exit of described air compressor machine is provided with the air door 21 exported for controlling compressed air, described main line 3 is provided with main line valve 31, described main line 3 is also provided with some bye-passes 4, any described bye-pass 4 is communicated with main line 3, any described bye-pass 4 is provided with branch road valve 41, equipment 5 and scavenging pipeline 51, any described bye-pass 4 is communicated with needing the equipment 5 carrying out purging operation by scavenging pipeline 51, described scavenging pipeline 51 is also provided with and purges switch 52.
Working method: can purge operation according to equipment needs optionally to open nitrogen making machine 1 or air compressor machine 2, by opening nitrogen valve or air door, the nitrogen of generation or compressed air are sent in each bye-pass 4 along main line 3, switch 52 is purged by manipulation, nitrogen or compressed air are injected along scavenging pipeline 51, purging operation is carried out to equipment 5.Compressed air pressure is 0.3-0.7MPa, and nitrogen storage tank pressure is 0.2-0.3MPa, all can the purging operation of finishing equipment from pressure, substantially accomplishes mutual use.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
