Pump monitoring device for methyl alcohol recovery technological process

Abstract

The invention discloses a pump monitoring device for a methyl alcohol recovery technological process. The pump monitoring device comprises a base. A pump volute is connected to one side of the top of the base through a bolt. A connecting sleeve is connected to one side of the pump volute through a bolt. A driving motor is connected to one end of the connecting sleeve through a bolt. The bottom of the driving motor is connected with the base through a bolt. According to the pump monitoring device, methyl alcohol is conveyed through a magnetic drive pump, meanwhile, a cooling jacket is used for cooling the magnetic connecting sleeve, the methyl alcohol conveying condition in the pump volute can be observed through a volute temperature gauge and a volute vibration meter, the motor operation condition can be judged through a motor vibration meter and a motor temperature gauge, the good methyl alcohol leakage early warning function is achieved through a methyl alcohol detector, and thus methyl alcohol leakage can be found in time; and methyl alcohol volatilized into air after leakage can be disposed through a protective cover and an exhaust tube, the risk of poisoning or explosion caused by methyl alcohol leakage is avoided, the recovery and production efficiencies are improved, and meanwhile, the lift and property safety of people is guaranteed.

Description

technical field [0001] The invention relates to the technical field of methanol recovery, in particular to a pump monitoring device for a methanol recovery process. Background technique [0002] Methanol is the simplest saturated monohydric alcohol with a boiling point of 64.7°C. It is a colorless and volatile liquid with an alcohol smell. The lowest dose of human oral poisoning is about 100mg / kg body weight, and oral intake of 0.3~1g / kg can be fatal. It is used in the manufacture of formaldehyde and pesticides, etc., and is used as an extraction agent for organic matter and a denaturant for alcohol. In the methanol recovery process The motor pump will be used to transport methanol. Since the motor pump is a moving device with many connection structures, most of the existing motor pumps only use the change of current to judge the operation status, and the leakage cannot be detected in time, resulting in no good performance. Methanol leak warning function, methanol leaks and...

In the methanol recovery process The motor pump will be used to transport methanol. Since the motor pump is a moving device with many connection structures, most of the existing motor pumps only use the change of current to judge the operation status, and the leakage cannot be detected in time, resulting in no good performance. Methanol leakage warning function, methanol leakage will cause the risk of poisoning or explosion after volatilization into the air, which will affect the recycling production and bring risks to people's lives and property
