Description
Technical field
It the utility model is related to technical field of chemical, and in particular to a kind of methanol storage tank of controllable flow rate.
Background technology
Emulsifying agent is during organic synthesis, and methanol is one of main reactant of emulsifying agent, and emulsifying agent synthesis technique exists
, it is necessary to strictly control methanol content in polymerization process, and methanol content is adjusted according to reaction process.Industrial production at present
In, the adjustment control of methanol content relies primarily on flow control valve to control flow, and flow control valve is when flow is turned down, methanol
Dnockout pumps inlet flow rate is constant, and rate of discharge diminishes, and methanol dnockout pumps internal pressure abruptly increase is serious to impeller, motor damage, very
Suppressed and stopped or motor is burnt out to methanol dnockout pumps；When flow control valve tunes up in flow, because rate of discharge is more than import
Flow, Flow-rate adjustment hysteresis, and methanol dnockout impeller of pump dallies, and easily burns out motor.
Utility model content
The purpose of this utility model is to solve the above problems, there is provided will not be to methanol during a kind of methanol flow regulation
Dnockout pumps causes the methanol storage tank of damage.
In order to solve the above problems, the technical solution adopted in the utility model is as follows：
A kind of methanol storage tank of controllable flow rate, including for depositing the tank body of methanol, the tank skin of tank body is cold to be connected with
But the double sandwich of medium, tank body top are provided with methanol charging aperture and exhaust outlet, and methanol discharging opening, methanol discharging are provided with below tank body
Mouth connection methanol dnockout pumps, methanol dnockout pumps outlet connecting pipe road are provided with flowmeter, it is characterised in that methanol dnockout pumps and stream
Return branch, return branch connection tank body top are provided between gauge, return branch is provided with magnetic valve, magnetic valve and flowmeter
Between be electrically connected with by controller.
Optimization of the present utility model, exhaust outlet connect water storage tank by pipeline, and the tube outlet of exhaust outlet connection gos deep into water
Below the water level of storage tank.
Compared with prior art, it is the advantages of the utility model：
（1）The utility model controls the methanol feed stream amount of methanol feed pipe by adjusting return branch uninterrupted,
Methanol dnockout pumps inlet and outlet flow is constant, will not be due to methanol dnockout pumps internal pressure during methanol flow is adjusted
Abruptly increase and methanol dnockout impeller of pump and motor are caused to damage.
（2）As long as ensure that methanol dnockout pumps rate of discharge is not less than required methanol flow, corresponding directly control and methanol
The flow control valve of dnockout pumps connection is compared, and the regulation of the utility model methanol flow is more accurate, is not in that Flow-rate adjustment is stagnant
Phenomenon afterwards.
