Description
Technical field
This utility model relates to the vent gas treatment field of fine chemistry industry, and exactly it is a kind of methacrylic acid special type ester
Class tower top does not coagulates the retracting device of gas.
Background technology
At present, special esters of methacrylic acid rectifier unit is all to use single vacuum system technology, this separation side
Method and device have the following disadvantages, and tower top discharging speed is fast, material is following in the gaseous state and condensation and direct by vacuum system
Take away, be then directly discharged in air by exhaustor, the most not environmentally, add again the loss of material, cause waste.Therefore
Do not coagulate Gas recovery during special esters of methacrylic acid rectification and become problem in the urgent need to address.
Summary of the invention
The purpose of this utility model is to provide a kind of methyl acrylic ester rectifier unit and does not coagulates gas concentration unit, its tool
There are multiple condensation, absorption, practicality simple to operate, and invest the features such as low, in order to solve not environmentally, increase again the damage of material
Consumption, causes the problems such as waste.
It is an object of the invention to be achieved through the following technical solutions: a kind of special esters of methacrylic acid tower top does not coagulates gas
The retracting device of body, true including secondary condenser, vacuum buffer tank, main lobe pump, two grades of lobe pumps, one-level lobe pump, water ring
Empty pump, absorbing liquid storage tank, absorption tower, it is characterised in that: condenser is secondary condenser, and secondary condenser (1) outlet connects true
Empty buffer tank (2) entrance, vacuum buffer tank (2) outlet is connected to vacuum pump set main lobe pump (3) entrance, and vacuum pump set connects successively
Connecing order is main lobe pump (3), two grades of lobe pumps (4), one-level lobe pump (5), water-circulating pumps (6), vacuum pump set Water-ring vacuum
Pump (6) outlet connects the entrance of absorbing liquid storage tank (7), and the cooling water inlet of vacuum pump set water ring vacuum pump (6) connects absorbing liquid
The outlet of storage tank (7).The air vent of absorbing liquid storage tank (7) connects the entrance on absorption tower (8), and the outlet of absorption tower (8) connects puts
Blank pipe line.
This invention carries out part change and adds new equipment existing apparatus, specific as follows:
Condenser is B-grade condensation, and shell working media is the coolant media that temperature is lower.
Having coil pipe to condense in vacuum buffer tank, in pipe, the cold media mass-energy of work effectively reduces the temperature by gas
Degree.
Vacuum pump set is closed circulation system, and its water ring vacuum pump working media be instead of water by absorbing liquid, so can be right
Do not coagulate gas to absorb.
The utility model has the advantages that tower top does not coagulates gas through B-grade condensation, vacuum buffer tank cooling, vacuum water ring pump
Cooling medium liquid absorbs, absorption tower absorbs four times and recycles not solidifying extraordinary esters gas, reduces and gets rid of esters in gas
Content, economic and environment-friendly, the material simultaneously collected can recycle increase benefit, and can guarantee that a stable vacuum systems etc.
Feature.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 secondary condenser；2 vacuum buffer tanks；3 main lobe pumps；4 two grades of lobe pumps；5 one-level lobe pumps；6 water rings
Vacuum pump；7, absorbing liquid storage tank；8, absorption tower.
Detailed description of the invention
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
Secondary condenser outlet connects vacuum buffer tank entrance.
Vacuum buffer tank outlet is connected to vacuum pump set main lobe pump entrance.
It is main lobe pump, two grades of lobe pumps, one-level lobe pump, water-circulating pumps that vacuum pump set is sequentially connected with order.
The outlet of vacuum pump set water-circulating pump connects the entrance on absorption tower.
The outlet on absorption tower connects blow-down pipe.
The coolant outlet of vacuum pump set water-circulating pump connects the entrance of absorbing liquid storage tank, vacuum pump set water-circulating pump cold
But water inlet connects the outlet of absorbing liquid storage tank.
Work process: do not coagulate gas and first pass through secondary condenser and condense, residue is not coagulated gas and is entered vacuum buffer
In tank, being again condensed when coil pipe by being connected with coolant media, residue is not coagulated gas and is passed sequentially through vacuum pump set
Main lobe pump, two grades of lobe pumps, one-level lobe pumps to water circulation vacuum pump, the working media in water circulation vacuum pump is changed into by water
Absorbing liquid is discharged after not coagulating GAS ABSORPTION, and residue is not coagulated gas and is discharged into outside air after the absorption on absorption tower.Inhale
Also being provided with coil pipe facility in receiving liquid storage tank, the temperature being used for reducing absorbing liquid also meets water ring vacuum pump to working media temperature simultaneously
The requirement of degree, keeps one and stablizes vacuum.The material recycle that vacuum buffer tank and absorption tower periodic exhaustion condense out,
Absorbing liquid also regularly replaces recycling.
