Flowmeter and styrene tar loading pipeline system provided with flowmeter

Abstract

The invention relates to the technical field of chemical metering, in particular to a flow meter and a styrene tar loading pipeline system provided with the flow meter, which comprises a body, a sealing assembly, a first flange plate, two processing boxes and a second flange plate, the first flange plate and the two processing boxes are respectively arranged on two sides of the body, and the processing boxes are respectively connected with one side of the first flange plate of the body through connecting assemblies. The sealing assembly is movably inserted into the processing boxes, the sealing assembly comprises a sealing plate and a control assembly, the control assembly is arranged on one side of the upper end in the processing box, the processing boxes are connected to the two sides of the body of the mass flow meter respectively, and then under the action of the sealing plate in the processing boxes, the processing boxes are arranged in the processing boxes. The working function and the cleaning function of the flow meter are switched, when cleaning is needed, a pipeline of the whole flow meter is communicated with the outside through the injection groove of the sealing plate, the flow meter can be conveniently and independently cleaned, and the operation for processing the sealing plate is easy to control, convenient to use and high in stability.

Description

technical field [0001] The invention relates to the technical field of chemical metering, in particular to a flowmeter and a styrene tar loading pipeline system installed with the flowmeter. Background technique [0002] Styrene tar is a by-product of styrene production. When pumping ethylene tar for tanking and transportation, it is necessary to use a mass flow meter for metering control. Because the coke in styrene tar is easy to precipitate and form hard coke, it is very difficult It is difficult to remove, so after the sedimentation and agglomeration on the inner wall of the mass flowmeter, it needs to be dealt with in time, otherwise it will greatly affect the accuracy of the measurement efficiency. Due to the need for full contact reaction, the flowmeter is mostly disassembled and cleaned separately, which leads to cumbersome operation and reduces the efficiency of the operation. If the entire pipeline is cyclically cleaned, the cleaning cost will increase significantl...

[0002] Styrene tar is a by-product of styrene production. When pumping ethylene tar for tanking and transportation, it is necessary to use a mass flow meter for metering control. Because the coke in styrene tar is easy to precipitate and form hard coke, it is very difficult It is difficult to remove, so after the sedimentation and agglomeration on the inner wall of the mass flowmeter, it needs to be dealt with in time, otherwise it will greatly affect the accuracy of the measurement efficiency. Due to the need for full contact reaction, the flowmeter is mostly disassembled and cleaned separately, which leads to cumbersome operation and reduces the efficiency of the operation. If the entire pipeline is cyclically cleaned, it will cause a significant increase in cleaning costs and is extremely inconvenient to use.
