Individual through hole.
The beneficial effect that the utility model is reached is：
1. the reaction time is short, side reaction is few, under the conditions of continuous reaction, and the high-temperature residence time of material is only that batch (-type) is anti-
1/3 answered, side reaction greatly reduces, while oxirane and acrylic acid unit consumption have also declined；
2. Installed System Memory material is few, safe, to produce per year in 5000 tons of device calculating, course of reaction, always deposited in reactor
About 1 ton of doses, is that material and temperature lowering water recoverable amount are about 1 in the 1/10 of still reaction retaining amount, equipment：5, if occurring having a power failure
Abnormal conditions, are effectively reduced temperature runaway phenomenon；
3. energy consumption is low, heating once, starts after reaction when continuous reaction need to only start, and heat of reaction self-sufficiency can be achieved,
Once calculated by every monthly repair, driving and parking energy consumption is the 1/60 of intermittent reaction, steam consumption can be neglected；
4. the obvious reduction of nitrogen consumption, need to only carry out nitrogen displacement, normal continuous operation bar in first drive to equipment
Under part, nitrogen is no longer consumed in theory；
5. equipment making cost is low, part in compression is pipeline in reaction, and bearing capacity is strengthened, and equipment, which is sorted out, does not belong to pressure appearance
Device, equipment making cost reduction, cost of installation and maintenance has not also dropped；
6. auxiliary material operating cost is low, because the residence time is short, consumption inhibition dosage is reduced, the special consumption of polymerization inhibitor 705
About the 1/2 of still reaction.
