Description
Technical field
This utility model is related to protected against explosion centrifuge, in particular to centrifuge nitrogen explosion protection system.
Background technology
Centrifuge is applied in many fields of the national economy such as industry such as chemical industry, pharmacy extremely extensively, and which is still in current chemical industry
The capital equipment of solid-liquid separation in the production technologies such as mesosome, medical material medicine.The occasion applied due to these industry centrifuges,
The difference of technique, the physics of medium and chemical property, also has different requirements to centrifuge, and such as, material is required, structure will
Ask, requirement for anticorrosion, requirement of explosion proof etc..The centrifuge nitrogen protection for generally adopting at present, is actually simply provided with casing
One nitrogen inlet duct, a nitrogen out of the trachea, centrifuge operationally, to being filled with nitrogen in inner chamber.As for nitrogen gas concn energy
No reach safety range then without quantitative control, therefore, the reliability of its nitrogen protection is very poor.
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model is to provide a kind of centrifuge nitrogen explosion protection system, and which is right
The oxygen concentration in centrifuge and centrifuge corollary equipment in running detected, carries out nitrogen quantitative compensation mechanism,
Control oxygen content is within safety range.
For reaching above-mentioned purpose, the technical solution of the utility model is as follows：
Centrifuge nitrogen explosion protection system, mainly by PLC, oxygen content monitoring modular and nitrogen complementary module group
Into；The oxygen content monitoring modular includes oxygen content tester, each pneumatic diaphragm pump of detected gas filter, described pneumatic every
Membrane pump is connected between the oxygen content tester and the detected gas filter；The nitrogen complementary module is mainly by nitrogen
Source and nitrogen gas filters composition, the nitrogen gas filters have two escape pipes, be provided with every escape pipe electromagnetic valve and
Manual throttle valve, wherein one escape pipe are connected to the top of centrifuge, and the bottom of centrifuge has nitrogen exhaust pipe, separately
An outer escape pipe is connected in the dry gas seals mechanism in centrifuge.
Pneumatic diaphragm pump inhales the gas in centrifuge after the filtration of detected gas filter, reaches and enters in oxygen content tester
Row oxygen content is tested, if the concentration of oxygen content is higher than the preset value in PLC, nitrogen is conveyed by source nitrogen by trachea
Air ejection is completed to replace in the cavity of centrifuge.For some centrifuges for being provided with dry gas seals mechanism, its
The dry gas for adopting is also for nitrogen.During centrifuge startup work, source nitrogen continues to inject height in the dry gas seals mechanism of centrifuge
Pressure nitrogen.
It is further in the corollary equipment of centrifuge, also to be provided with oxygen content monitoring modular, the oxygen content monitoring mould
Block carries out data exchange with PLC；An escape pipe is additionally provided with nitrogen gas filters, and the escape pipe is connected to centrifuge
In corollary equipment.In the corollary equipment of centrifuge as temperature, burning things which may cause a fire disaster, the oligomerisation of oxygen three elements and explode, institute
During detecting the oxygen content in corollary equipment when oxygen content detection module higher than setting value in PLC, source nitrogen
Into corollary equipment, nitrogen injection is exhausted.
It is further that the drain pipe of the centrifuge is U-tube, carries out fluid-tight using U-tube, can be effectively prevented
In the inclusion of air centrifuge of on-site.
The centrifuge nitrogen explosion protection system provided by above-mentioned technical proposal, this utility model, which can be to running
In centrifuge and centrifuge corollary equipment in oxygen concentration detected, carry out quantitative control, improve nitrogen explosion-proof
The reliability of system.
Description of the drawings
For the technical scheme being illustrated more clearly that in this utility model embodiment, below will be to needed for embodiment description
Accompanying drawing to be used is briefly described.
Fig. 1 is the structural representation of the centrifuge nitrogen explosion protection system disclosed in the present embodiment.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe.
Referring to Fig. 1, centrifuge nitrogen explosion protection system, mainly supplemented by PLC, oxygen content monitoring modular and nitrogen
Module is constituted；Oxygen content monitoring modular includes oxygen content tester, each pneumatic diaphragm pump of detected gas filter, pneumatic diaphragm
Pump is connected between oxygen content tester and detected gas filter；Nitrogen complementary module is mainly by source nitrogen and nitrogen gas filters
Composition, nitrogen gas filters have three escape pipes, are provided with electromagnetic valve and manual throttle valve in every escape pipe, wherein one
Escape pipe is connected to the top of centrifuge, and the bottom of centrifuge has nitrogen exhaust pipe, and in addition an escape pipe is connected to centrifugation
In dry gas seals mechanism in machine, last root escape pipe is connected to the on-site at centrifuge place.
Pneumatic diaphragm pump inhales the gas in centrifuge after the filtration of detected gas filter, reaches and enters in oxygen content tester
Row oxygen content is tested, if the concentration of oxygen content is higher than the preset value in PLC, nitrogen is conveyed by source nitrogen by trachea
Air ejection is completed to replace in the cavity of centrifuge.For some centrifuges for being provided with dry gas seals mechanism, its
The dry gas for adopting is also for nitrogen.During centrifuge startup work, source nitrogen continues to inject height in the dry gas seals mechanism of centrifuge
Pressure nitrogen.When the oxygen content that oxygen content detection module is detected in corollary equipment is higher than the setting value in PLC, nitrogen
Source of the gas carries out nitrogen displacement to relevant device nitrogen injection.
It is further that the drain pipe of centrifuge is U-tube, carries out fluid-tight using U-tube, can be effectively prevented plant area
In interior inclusion of air centrifuge.
The centrifuge nitrogen explosion protection system provided by above-mentioned technical proposal, this utility model, which can be to running
In centrifuge and centrifuge corollary equipment in oxygen concentration detected, carry out quantitative control, improve nitrogen explosion-proof
The reliability of system.
Multiple modifications of these embodiments will be apparent for those skilled in the art, herein
Defined General Principle can be real in other embodiments in the case of without departing from spirit or scope of the present utility model
Existing.Therefore, this utility model is not intended to be limited to the embodiments shown herein, and be to fit to disclosed herein
The consistent most wide scope of principle and features of novelty.
