Abstract
Disclosed is a pre-reaction dehydration device for alcohol ether production. The pre-reaction dehydration device for alcohol ether production comprises an initiator charge pump (7), a pre-reaction machine (8), a vacuum pump (10), a dehydration dryer (1), an air liquid separator (2), a heat exchanger (4), a steam-jet pump (3) and an atmosphere faded pool (9). Alcohol and catalysts are added from a raw material adding inlet of the pre-react machine and the vacuum pump is used for vacuum dehydration, at the same time, under the dynamic effect of the initiator charge pump, raw materials loops dynamically according to the line of a pre-reaction retort, the initiator charge pump, the dehydration dryer and the pre-reaction retort, and therefore the evaporation of water is accelerated. Evaporated water enter into a heat exchanger shell side through a steam ejecting pump, and is poured into the atmosphere fade pool after being condensed into water. A liquid sealing pool and an overflow blocking board are arranged inside the atmosphere fade pool, and the atmosphere fade pool guarantees that air is not sucked into the system during the vacuuming process. The condensed water is poured into a sewage disposing center from the atmosphere fade pool. The pre-reaction dehydration device for alcohol ether production has the advantages that the dehydration efficiency is high, moisture content of materials after being pre-reacted is low, load of the vacuum pump is low and the electric energy is saved.
Description
Technical field
The utility model relates to the structure that improves the device of vacuum dehydration effect in a kind of alcohol ether production pre-reaction, a kind of alcohol ether production pre-reaction dewater unit.
Background technology
The alcohol ether production pre-reaction technological process of production is: under high temperature and negative pressure, pure and mild catalyst dehydration generates the start of chain agent, by the effect that heating and vavuum pump vacuumize the moisture content in raw material and the catalyst is sloughed.The pure and mild catalyst that has taken off water enters into next step reaction.Existing pre-reaction dehydration adopts vavuum pump to vacuumize the mode of dehydration, only depends on the agitator of pre-reaction tank to stir, and disengagement area is little, the moisture slow evaporation, and yielding poorly of long, unit interval time that vacuumizes, of poor benefits, energy consumption is large.
Summary of the invention
The utility model is intended to propose a kind of alcohol ether production pre-reaction dewater unit, improves dewatering efficiency, and reduces the moisture content of material after the pre-reaction.
This alcohol ether production pre-reaction dewater unit comprises initiator feed pump, pre-reactor, vavuum pump, dehydrate device, gas-liquid separator, heat exchanger, steam jet pump and atmosphere takes off the pond.There is a raw material to add entrance on the pre-reactor, the discharging opening of pre-reactor links to each other with the import of initiator feed pump, initiator charging delivery side of pump links to each other with the charging aperture that dehydrates device by valve, the material outlet that dehydrates device links to each other with the material inlet of pre-reactor, the steam (vapor) outlet that dehydrates device links to each other with the material inlet of gas-liquid separator, the gas vent of gas-liquid separator links to each other with the charging aperture of steam jet pump, the outlet of steam jet pump links to each other with the steam inlet of heat exchanger, the condensate outlet of heat exchanger links to each other with the import that atmosphere takes off the pond, and the bleeding point of heat exchanger links to each other with the import of vavuum pump.
During this alcohol ether production pre-reaction dewater unit work, add entrance from the raw material of pre-reactor and add pure and mild catalyst, carry out vacuum dehydration with vavuum pump, simultaneously under the dynamic action of initiator feed pump, raw material carries out dynamic circulation according to the route of pre-reaction tank → initiator feed pump → dehydrate device → pre-reaction tank, is conducive to the evaporation of moisture content; The moisture content of evaporation enters heat exchanger shell pass through gas-liquid separator and steam jet pump, be condensed into and enter atmosphere behind the water and take off the pond, it is fluid-tight pond and overflow baffle that atmosphere takes off the pond inner, guarantees vacuumizing Shi Buhui with air suction system, and condensed water takes off the pond by atmosphere and enters treatment center of sewage.This alcohol ether production pre-reaction dewater unit dewatering efficiency is high, and the moisture content of material is low after the pre-reaction, and the vavuum pump load is low, electric energy is economized.
Description of drawings
Accompanying drawing is the structure principle chart of this alcohol ether production pre-reaction dewater unit.
The specific embodiment
As shown in the figure, this alcohol ether production pre-reaction dewater unit comprises initiator feed pump 7, pre-reactor 8, vavuum pump 10, dehydrates device 1, gas-liquid separator 2, heat exchanger 4, steam jet pump 3 and atmosphere and take off pond 9.There is a raw material to add entrance 82 on the pre-reactor 8, the discharging opening 83 of pre-reactor links to each other with the import of initiator feed pump 7, initiator charging delivery side of pump links to each other with the charging aperture 11 that dehydrates device 1 by valve 5,6, valve 5 is hand-operated valves, be used for controlling material and enter the flow that dehydrates device 1, valve 6 is autocontrol valves, only has standard-sized sheet or complete shut-down state.The material outlet 12 that dehydrates device links to each other with the material inlet 81 of pre-reactor, the steam (vapor) outlet 13 that dehydrates device links to each other with the material inlet 21 of gas-liquid separator 2, the gas vent 23 of gas-liquid separator links to each other with the charging aperture 31 of steam jet pump 3, the outlet 32 of steam jet pump links to each other with the steam inlet 41 of heat exchanger 4, the import that condensate outlet 42 and the atmosphere of heat exchanger takes off pond 9 links to each other, and the bleeding point 43 of heat exchanger links to each other with the import of vavuum pump 10.
As shown in the figure, add the pure and mild catalyst of entrance 82 addings from the raw material of pre-reactor 8, vacuumize with vavuum pump 10 and to dewater, simultaneously under the dynamic action of initiator feed pump 7, raw material enters by initiator feed pump 7 from pre-reactor 8 and dehydrates device 1, turn back to again pre-reactor 8, dynamic circulation.Dehydration is carried out with dehydrating in the device simultaneously at pre-reactor, and pre-reactor will heat.The moisture content of evaporation enters gas-liquid separator 2, isolates water vapour behind the light component material is sucked heat exchangers 4 by steam jet pump 3 shell side, is condensed into to enter atmosphere behind the water and take off pond 9.Steam jet pump is to strengthen vacuum, and in the vacuum decline of vavuum pump, when not reaching needed standard, the unlatching steam jet pump is strengthened vacuum.Atmosphere takes off that pond 9 is inner to be fluid-tight pond and overflow baffle 91, guarantees air to be entered system from the discharge outlet back suction vacuumizing Shi Buhui, and condensed water takes off the pond by atmosphere and enters treatment center of sewage.The start of chain agent of finishing after the dehydration is transported to the main reaction system by initiator feed pump 7 from pre-reaction tank 8.
Carry out pre-reaction with this alcohol ether production pre-reaction dewater unit, resulting start of chain agent water content is down to about 0.02% by 0.06%, the PEG(polyethylene glycol of product) is down to about 0.5 ~ 0.8% by original 1 ~ 1.5%, the time that shortens dehydrating operation approximately 40%, saved electric energy, increase output about 10%, realized simultaneously environmental protection production.
