Abstract

The utility model provides a poor methanol filtration system, include through the same two way pipeline A and pipeline B that link to each other with the material export, parallelly connected between pipeline A and the pipeline B, the last gate valve I that has set gradually of pipeline A, poor methanol filter and gate valve two, the output of poor methanol filter passes through gate valve three and connects methyl alcohol blowdown pipe reason, the back flush pipeline of the parallelly connected all the way on the pipeline department of poor methanol filter input and the pipeline of three exits of gate valve, the back flush pipeline is last to set gradually gate valve four and gate valve five, be provided with the blind plate between gate valve four and the gate valve five, gate valve six parallelly connected all the way on the gate valve one. The utility model discloses switch the clearance mutually under the condition of operation in-process filter core jam, a newly-increased back flush backflow pipeline behind filter inlet valve simultaneously arranges the impurity-containing methyl alcohol after the washing to the methyl alcohol blow off pipe to reduce the clearance frequency.

Description

Poor methanol filtration system

Technical Field

The utility model relates to a poor methanol filter technical field, in particular to poor methanol filtration system.

Background

Poor methyl alcohol filter bottom pump export poor methyl alcohol filter, the impurity that the filtration system operation in-process produced, former design is single filter, at present according to the actual operation condition in scene, poor methyl alcohol in the system contains impurity quantity more, and poor methyl alcohol filter blocks up too frequently, and filter is once cleared up on average two days, and at every filter core clearance change in-process, the medium passes through the bypass line, can bring partial impurity into the system, influences poor methyl alcohol absorption effect, produces the damage to the mechanical seal of methyl alcohol pump simultaneously.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model aims to provide a poor methanol filtering system switches the clearance mutually under the condition of operation in-process filter core jam, and a newly-increased back flush backflow pipeline is arranged to the methanol blow off pipe including impurity methanol after will washing simultaneously behind the filter import valve to reduce the clearance frequency.

In order to realize the purpose, the utility model discloses a technical scheme is:

The utility model provides a poor methanol filtration system, includes two the same way pipeline A1 and pipeline B2 that link to each other with the material export, parallelly connected between pipeline A1 and the pipeline B2, pipeline A1 on set gradually gate valve 3, poor methanol filter 4 and two 5 of gate valve, the output of poor methanol filter 4 pass through three 6 connection methanol blowdown ground pipes 11 of gate valve, the pipeline department of 4 inputs of poor methanol filter and the pipeline at the three 6 exits of gate valve on the back flush pipeline of parallelly connected all the way, the back flush pipeline on set gradually gate valve four 7 and five 8 of gate valve, be provided with between gate valve four 7 and five 8 of gate valve blind plate 9, gate valve 3 on parallelly connected all the way pressure-equalizing valve six 10 of gate valve.

The gate valve I3 and the gate valve II 5 are 6-inch 300LB, and the gate valve III 6, the gate valve IV 7, the gate valve V8 and the gate valve VI 10 are 2-inch 300 LB.

The lean methanol filter 4 is a lean methanol filter S1602.

The utility model has the advantages that:

The purpose of filter is the purpose of detaching machinery and solid impurity in the operation medium, and this novel device can realize independently clearing up of filter under the condition that guarantees that the medium does not leak, has saved the consumption of the produced manpower resources waste and consumptive material of maintenance in-process, has guaranteed the cleanliness of operation medium, and safe pollution-free, the extravagant realization filter core clearance of nothing.

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1:

The connection mode of all parts of the equipment is mainly flange connection, two identical pipelines are arranged on the structure of the device, one pipeline is standby, a back flush pipeline is newly added on an inlet pipeline of the poor methanol filter 4, in the using process, a first gate valve 3 of an inlet valve of the standby poor methanol filter 4 is closed, a blind plate 9 is conducted, a second outlet gate valve 5, a fourth gate valve 7 of the back flush pipeline and a fifth gate valve 8 of the back flush pipeline are opened, the purpose that the medium at the outlet of the bypass equipment enters the standby equipment in the reverse direction, the impurity-containing polluted methanol enters a pollution discharge methanol pipe 11, and the purpose of back flushing and cleaning a filter.

The two devices are connected in parallel. And constructing the newly-added equipment foundation according to the civil engineering foundation requirement of the chemical equipment.

Before the pipeline construction of the newly-added equipment, the system must be reliably isolated, the equipment is washed and replaced to be qualified, and the fire-extinguishing requirement is met.
