Description

Technical Field

[0001] This utility model relates to the field of methanol production, specifically a methanol booster device. Background Technology

[0002] Methanol is a simple saturated monohydric alcohol that is a colorless and transparent liquid at room temperature. It is highly volatile, readily soluble in water, and also toxic and flammable. As an important basic chemical raw material, it is widely used in the production of chemical products such as acetic acid.

[0003] During methanol production, it needs to be pressurized during transportation. However, current pressurization equipment is prone to liquid flash evaporation when increasing the pressure, which will form a gas-liquid mixture, leading to a decrease in transportation efficiency and even equipment cavitation damage, affecting the stability of methanol pressurization. To address these issues, we propose a methanol pressurization device. Utility Model Content

The booster pump 5 is the core equipment for methanol boosting, which can pressurize pretreated methanol and deliver it through the outlet pipe 6. By setting up the buffer tank 2, the volume effect of the buffer tank 2 can stabilize the liquid pressure and reduce instantaneous flow rate fluctuations. In addition, the gas-liquid separator 4 can separate trace bubbles in the liquid to ensure that the medium entering the booster pump 5 is a single-phase liquid.

Through the upper connecting flange 18, the lower connecting flange 19, and the connecting pipe 20, a conveying channel from the gas-liquid separator 4 to the booster pump 5 can be formed, ensuring that the liquid entering the booster pump 5 is a single-phase liquid. Through the two mounting plates 13 and the mounting holes 14, it is easy to fix the entire device on the ground or on a bracket. The reinforcing support 17 reinforces the booster pump 5.

Inlet pressure sensor 8 monitors the methanol pressure entering buffer tank 2 in real time. Discharge flange 11 facilitates connection with downstream pipeline to realize the external output of pressurized methanol. Outlet pressure sensor 21 can monitor the pressurized methanol pressure. Flow meter 22 measures the output flow. The cooperation of both and inlet pressure sensor 8 can transmit data to PLC controller 15.

[0026] Working principle: First, methanol enters buffer tank 2 through injection pipe 7. Inlet pressure sensor 8 monitors the inlet pressure in real time. Then, buffer tank 2 uses volume effect to stabilize liquid pressure and reduce instantaneous flow rate fluctuations. Then, the pre-treated methanol enters gas-liquid separator 4 through output pipe 3, which can separate trace bubbles in the liquid to ensure that the medium entering booster pump 5 is a single-phase liquid. Then, the methanol processed by gas-liquid separator 4 enters booster pump 5 through upper connecting flange 18, lower connecting flange 19 and connecting pipe 20 in sequence. The pressurized methanol is transported through liquid outlet pipe 6.
