Abstract
The invention discloses a gas supply system for a benzene hydrogenation device. The system comprises an air compressor, a buffer tank connected with the air compressor, a nitrogen storage tank, a nitrogen tube connected with the nitrogen storage tank and a communication tube. An instrument air pipe is connected with the buffer tank, the air feeding end of the communication tube is connected with the nitrogen tube, the air discharging end of the communication tube is connected with the instrument air tube, and a valve and a check valve are arranged on the communication tube. During emergent instrument air stopping, nitrogen can be supplied for the instrument air tube continuously by only opening the valve, so that sufficient gas is supplied for an adjustment system on the benzene hydrogenation device, the conducting of the production is guaranteed within certain time, conditions are created for operations such as emergent stopping of operators, and the operation stability and the production safety are guaranteed.
Description
Technical field
The invention belongs to chemical industry equipment, relate in particular to a kind of air supply system for benzene hydrogenation device.
Background technique
Benzene hydrogenation device instrument wind used be the air through compression drying, is the original power of automatic production operation, and not had instrument to produce humorously cannot carry out, even short a few minutes.But the accident such as have a power failure in production process will inevitably cause the cut-off of instrument wind, and the instrument wind knock out drum of benzene hydrogenation is also smaller, also can only maintain the very short time if had a power failure.But the amount of nitrogen is but very sufficient on benzene hydrogenation device, there is the large storage tank of two 1000m3, nitrogen is that on device, each tower is used for pilot pressure, and nitrogen is also a kind of cleaner power gas.
Summary of the invention
The object of this invention is to provide a kind of air supply system for benzene hydrogenation device, can solve the problem of the instrument wind cut-off occurring in production.
For achieving the above object, the present invention adopts following technological scheme: a kind of air supply system for benzene hydrogenation device, comprise air compressor and coupled knock out drum, instrument wind pipeline is connected with knock out drum, also comprise nitrogen storage tank and coupled nitrogen pipeline, also comprise connecting tube, the inlet end of connecting tube is connected with nitrogen pipeline, the outlet side of connecting tube is connected with instrument wind pipeline, and valve and one-way valve were housed on connecting tube.
Connecting tube is connected by a threeway with instrument wind pipeline, between threeway and knock out drum, valve is housed.
Adopt the air supply system of technique scheme, by connecting tube nitrogen pipeline and instrument wind pipeline being coupled together, valve and one-way valve are housed on connecting tube, only need open this valve while promptly stopping instrument wind running into, supply nitrogen that just can be lasting, to instrument wind pipeline, makes regulating system on benzene hydrogenation device have sufficient source of the gas, has ensured within a certain period of time the carrying out producing, create condition for operator's operation such as stop in emergency, ensured the stable safety with producing of operation.

A kind of air supply system for benzene hydrogenation device as shown in Figure 1, comprise air compressor 1 and coupled knock out drum 2, instrument wind pipeline 4 is connected with knock out drum 2, also comprise nitrogen storage tank 8 and coupled nitrogen pipeline 9, also comprise connecting tube 5, the inlet end of connecting tube 5 is connected with nitrogen pipeline 9, and the outlet side of connecting tube 5 is connected with instrument wind pipeline 4, and valve 7 and one-way valve 6 were housed on connecting tube 5.Connecting tube 5 is connected by a threeway 3 with instrument wind pipeline 4, between threeway 3 and knock out drum 2, valve is housed.After connecting like this, nitrogen can be incorporated in instrument wind pipeline, and instrument wind can never import nitrogen system into.
Only need open the valve on connecting tube while promptly stopping instrument wind running into, supply nitrogen that just can be lasting is to instrument airduct line, make regulating system on benzene hydrogenation device have sufficient source of the gas, ensure within a certain period of time the carrying out producing, for operator's operation such as stop in emergency creates conditions, the stable safety with producing that ensures operation, has larger economic value.
Claims (2)
1. the air supply system for benzene hydrogenation device, comprise air compressor and coupled knock out drum, instrument wind pipeline is connected with knock out drum, also comprise nitrogen storage tank and coupled nitrogen pipeline, it is characterized in that: also comprise connecting tube, the inlet end of connecting tube is connected with nitrogen pipeline, and the outlet side of connecting tube is connected with instrument wind pipeline, and valve and one-way valve were housed on connecting tube.
2. the air supply system for benzene hydrogenation device as claimed in claim 1, is characterized in that: connecting tube is connected by a threeway with instrument wind pipeline, between threeway and knock out drum, valve is housed.
