The utility model is characterized in that the entire gasifier for producing morpholine consists of the DEG preheater, the ammonia preheater, the electric heater and the material gasifier which are all connected via the pipelines and finally gathered into the material gasifier to perform final gasification of the material DEG; the material gasifier comprises two layers of structured stainless-steel silkscreen fillers; a material DEG inlet re-distributor is positioned between the upper and the lower layers of fillers; and a stainless-steel wire mesh demister is arranged at the gas phase outlet of the material gasifier. By adopting two sections of improved structured fillers stacking method, the material gasifier can greatly improve mass and heat transfer effects of the material; and uniform serial of gas flow can ensure good gasification effect of the material.
Description
Technical field:
The utility model belongs to morpholine (1,4-oxygen, azo-cycle hexane) production technical field, relates in particular to the gasifier device that a kind of vapor phase method is produced morpholine.
Background technology:
At present, what the gasification installation of China's production morpholine generally adopted is that 5mm～10mm open column shape porcelain ring huddles in airtight tubular steel vessel, hole comb as the material inlet distributor pipe with the fan-shaped that ordinary carbon steel is made, carry out material (diethylene glycol) gasification technology, the technological deficiency that it exists is:
1, owing to be that what to adopt is the random stacking of porcelain ring, then need the air-flow skewness of the material (diethylene glycol) that gasifies, cause the material heat-transfer effect poor, influence the gasification efficiency of material (diethylene glycol).
2, owing to be the carrier of porcelain ring as material (diethylene glycol) gasification, its mass transfer effect is poor, causes material (diethylene glycol) gasification rate slow, also influences the gasification efficiency of material (diethylene glycol).
3, the material of its carbon steel material (diethylene glycol) gasification import comb boring formula distributor pipe, material enters the weak effect of distribution again in the cylindrical shell, production practices prove in addition, and carbon steel material is to cause material (diethylene glycol) very easily to tie carbon, are difficult for a very important inducement of gasification.
4, because material (diethylene glycol) can not enter the back operation with good vaporized state, just increased the load of back workshop section, caused the synthetic transformation efficiency of back workshop section poor, yield is low.
Summary of the invention:
For overcoming the technological deficiency that exists on the present production morpholine gasification installation, the utility model discloses a kind of high-efficiency gasification, and simple and reasonable vapor phase method is produced the gasifier device of morpholine.
The concrete technical scheme that the utility model is dealt with problems is:
A kind of device of producing the modified gasifier of morpholine, by the diethylene glycol preheater, ammonia preheater, electric heater, the material gasifier, reactor, material heat exchanger, product cooler, gas-liquid separator, synthetic liquid intermediate storage tank, circulator, measuring pump constitutes, connect by pipeline between them, it is characterized in that: by the diethylene glycol preheater, ammonia preheater, electric heater, the material gasifier is formed the whole gasification installation that morpholine is produced, connect by pipeline between each equipment, finally all be aggregated in the material gasifier, carry out the gasification eventually of material (diethylene glycol).
Described material gasifier is that the regular wire packing of two-layer stainless steel is up and down arranged, and is that material (diethylene glycol) import redistributor constitutes between the two-layer filler, and material gasifier gaseous phase outlet is equipped with a stainless steel cloth demister.
The advantage of technical solutions of the utility model is:
1, the upper and lower two sections structured packing accumulation modes after the utilization of material vaporizer improves in this device have improved the mass transfer and the heat-transfer effect of material greatly.Air-flow serial simultaneously is even, makes the material gasification result good.
2, utilize follow-on material gasification import redistributor device, improved the distribution effect again of material, thus suitable prolongation the gasification time of material, increased material gasification probability
3, the stainless steel cloth demister that utilizes epimere to increase can well will also not have the liquid phase material interception of gasification to live, the baffling back-mixing, and the material of having avoided not gasifying enters back workshop section, thereby increases the load of back workshop section.
4, in sum, utilize this modified material gasifier, the material gasification that can will enter vaporizer to greatest extent is complete, calculate according to production practices, the rate of gasification of material can reach 90%, than with former design technology rate of gasification 75%, rate of gasification improves nearly 15 percentage points.Make the Synthesis conversion of back workshop section greatly improve, be increased to 62%～65% by original average 57%～60% conversion ratio, the material income is greatly considerable, has also prolonged the service life of morpholine catalyst simultaneously, thereby has improved the cycle of operation and the production cost of device greatly.
