After the material distribution is finished, acrylonitrile and methacrylic acid are introduced into the reaction kettle 1 for polymerization reaction, the reaction is carried out under the constant temperature condition of water bath, gas discharged from the exhaust pipe 2 of the reaction kettle 1 mainly contains unreacted monomers and water vapor, when the gas flow reaches the liquid loading baffle 3, a small amount of water vapor and monomers are condensed into liquid on the lower surface of the liquid loading baffle 3 and flow to the pipe wall of the exhaust pipe 2 along with the lower surface of the liquid loading baffle 3 and then flow back to the reaction kettle 1; under the effect of loudspeaker form hydrops baffle 3, the air current is through the 15 upflow in air vent at 3 middle parts of hydrops baffle, run into 4 back most monomers of condensation mechanism and vapor and become liquid by the condensation, under the drainage effect of condensation mechanism 4, downflow to hydrops space, because the hydrops space is formed by hydrops baffle 3, its top is under the effect of sheltering from of hydrops baffle 3, the gas flow is more weak, the downflow of condensate can not influenced by the air current, the air current that also can not influence in blast pipe 2 simultaneously flows. The condensate liquid is accumulated in the liquid accumulation space and then enters a condensate liquid recovery system to realize recovery.
The drainage structure of the condensation mechanism 4 can be provided with a corresponding rod-shaped or plate-shaped drainage structure in the condensation mechanism 4, the cooling liquid can flow downwards through the inner wall of the exhaust pipe 2, and can also drip on the condensation mechanism 4, as long as the downward flow path of the condensate is ensured to be positioned above the effusion space and shielded by the effusion baffle 3.

Set up condensation mechanism 4 wholly to the drainage structure and compare in increasing other subsidiary drainage structures, its drainage efficiency is higher.
In order to ensure that the condensed liquid quickly flows down to the liquid loading space to be discharged so as to reduce the re-evaporation of the condensed liquid, a guide plate 5 is vertically arranged on the inner wall of the pipeline between the condensing mechanism 4 and the liquid loading space.

Although condensate recovery system can be directly through the hydrops spatial connection that pipeline and hydrops baffle 3 formed, because the hydrops space bottom that the hydrops space formed is narrow and small, can make the communicating opening of hydrops space and pipeline narrow and small, be unfavorable for the discharge of liquid, therefore, in the preferred embodiment of this application, be provided with annular inside groove 6 bottom hydrops baffle 3, condensate recovery system is connected with annular inside groove 6. Annular inner groove 6 can better accumulate liquid to be favorable to the unobstructed of condensate outer row.
