Abstract
The utility model discloses a novel methanol unloading system, which comprises an incoming liquid pipeline, a liquid outlet pipeline, an unloading pump, a gas-liquid separation tank and a return pipeline; the liquid outlet end of the unloading pump is also communicated with the inlet of the gas-liquid separation tank through an exhaust pipeline, and the liquid outlet at the bottom of the gas-liquid separation tank is communicated with the liquid inlet end of the unloading pump through a return pipeline; an exhaust valve is arranged on the exhaust pipeline. Has the advantages that: the exhaust gas and the methanol liquid discharged along with the gas enter the gas-liquid separation tank through an exhaust pipeline, the gas is discharged from a high point at the top gas outlet end of the gas-liquid separation tank, and the methanol liquid is temporarily left at the bottom of the gas-liquid separation tank. When the liquid level in the gas-liquid separation jar reached and predetermines the liquid level, open the reflux valve, during the methanol liquid that makes collection in the gas-liquid separation jar flows back to the system through backflow pipeline, methanol is whole like this in inclosed pipeline, can avoid methanol to splash and injure the people, has eliminated the potential safety hazard, has retrieved methanol again, saves labour and time, can also effectively improve the operational environment in the pump house, and the effect is showing.
Description
The technical field is as follows:
the utility model relates to an unloading system especially relates to a novel methyl alcohol unloading system.
The background art comprises the following steps:
methanol has very wide application and is a common chemical raw material for chemical enterprises. For some enterprises which do not have a methanol production line by themselves or can not produce methanol to meet the requirements of downstream production lines, a large amount of methanol is purchased every year; some large-scale enterprises need to unload hundreds of cars of methanol every day, so the start-stop frequency of the methanol unloading pump is high. According to the requirements of operating regulations, before starting the unloading pump, the outlet pipeline of the unloading pump needs to be exhausted, otherwise, cavitation is caused. The conventional exhaust design is that an exhaust valve is arranged in front of an outlet valve of an unloading pump, and the exhaust valve needs to be opened by one person during exhaust, and because methanol liquid can be exhausted along with gas, another person is required to take a barrel to receive the methanol liquid exhausted along with the gas, so that the labor and time are wasted in the exhaust process; and because methanol has pungent smell, the exhaust process still can cause the methanol smell in the pump house heavier, simultaneously, easily takes place the methanol and splashes and injures people's accident, has serious personal safety hidden danger.
The utility model has the following contents:
an object of the utility model is to provide a novel methyl alcohol system of unloading to solve above-mentioned problem.
The utility model discloses by following technical scheme implement:
a novel methanol unloading system comprises an incoming liquid pipeline, a liquid outlet pipeline, an unloading pump, a gas-liquid separation tank and a return pipeline;
the liquid outlet end of the liquid inlet pipeline is communicated with the liquid inlet end of the unloading pump, and the liquid outlet end of the unloading pump is communicated with the liquid inlet end of the liquid outlet pipeline; a liquid inlet valve is arranged on the liquid inlet pipeline, and a liquid outlet valve is arranged on the liquid outlet pipeline;
the liquid outlet end of the unloading pump is also communicated with the inlet of the gas-liquid separation tank through an exhaust pipeline, and the liquid outlet at the bottom of the gas-liquid separation tank is communicated with the liquid inlet end of the unloading pump through a return pipeline; an exhaust valve is arranged on the exhaust pipeline.
Furthermore, a liquid level sensor is arranged in the gas-liquid separation tank, and a return valve is arranged on the return pipeline.
Further, the gas outlet at the top of the gas-liquid separation tank is communicated with the atmosphere through a high-point emptying pipeline.
The utility model has the advantages that:
when the exhaust is needed, the exhaust valve is opened, the exhaust gas and the methanol liquid discharged along with the gas enter the gas-liquid separation tank through the exhaust pipeline, the gas is discharged from the top gas outlet end high point of the gas-liquid separation tank, and the methanol liquid is temporarily left at the bottom of the gas-liquid separation tank. When the liquid level in the gas-liquid separation jar reached and predetermine the liquid level, open the backward flow valve, during the methanol liquid that makes collection in the gas-liquid separation jar flows back to the system through the backflow pipeline, methanol is whole like this in inclosed pipeline, can avoid methanol to splash and injure the people, has eliminated the potential safety hazard, has retrieved methanol again, saves labour and time, can also effectively improve the operational environment in the pump house, and the effect is showing.
Description of the drawings:
in order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
