Abstract
The utility mode discloses an air supply system used for a benzene hydrogenation unit. The air supply system used for the benzene hydrogenation unit comprises an air compressor and a buffer tank connected with the air compressor. Instrument air piping is connected with the buffer tank. The air supply system used for the benzene hydrogenation unit further comprises a nitrogen storage tank and a nitrogen pipeline connected with the nitrogen storage tank, and furthermore comprises a communicating pipe. The air inlet end of the communicating pipe is connected with the nitrogen pipeline, and the air outlet end of the communicating pipe is connected with the instrument air pipeline. A valve and a one-way valve are further installed on the communicating pipe. According to the air supply system, the nitrogen pipeline and the instrument pipeline are connected through the communicating pipe, the valve and the one-way valve are installed on the communicating pipe, in the emergency of stopping the instrument air, only the valve needs to be opened, so that nitrogen can be continuously supplied to the instrument air piping, and therefore, an adjustment system on the benzene hydrogenation unit is provided with sufficient air sources. At certain time, the smooth production is guaranteed, conditions are created for operations including emergency cutoff of an operator and the like, and stability of the operations and safe production are guaranteed.
Description
Technical field
The utility model belongs to chemical industry equipment, relates in particular to a kind of air supply system for the benzene hydrogenation device.
Background technique
Benzene hydrogenation device instrument wind used is namely the air through compression drying, is the original power of automatic production operation, and not had instrument to produce humorously can't 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 keep the very short time if having a power failure.But on the benzene hydrogenation device, the amount of nitrogen is but very sufficient, and the large storage tank of two 1000m3 is arranged, and 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 purpose of this utility model is to provide a kind of air supply system for the benzene hydrogenation device, can solve the problem of the instrument wind cut-off that occurs in production.
For achieving the above object, the utility model adopts following technological scheme: a kind of air supply system for the benzene hydrogenation device, comprise air compressor and coupled knock out drum, the 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 the instrument wind pipeline, and valve and one-way valve were housed on connecting tube.
Connecting tube is connected by a threeway with the 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 were housed on connecting tube, only need open this valve when promptly stopping instrument wind running into, the supply nitrogen that just can continue is to the instrument wind pipeline, makes benzene hydrogenation device adjusted system that the source of the gas of abundance be arranged, and guaranteed within a certain period of time the carrying out of production, create condition for operator's operation such as stop in emergency, guaranteed the stable safety with producing of operation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of air supply system for the 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 the instrument wind pipeline, and instrument wind can never import nitrogen system into.
Running into the valve that only need open when promptly stopping instrument wind on connecting tube, the supply nitrogen that just can continue is to instrument airduct line, make benzene hydrogenation device adjusted system that sufficient source of the gas be arranged, guaranteed within a certain period of time the carrying out that produces, for operator's operation such as stop in emergency creates conditions, guarantee the stable safety with producing of operation, have larger economic value.
