Abstract
The utility model relates to a titanium catalyst production device, in particular to an ethylene glycol titanium production device system, which comprises a reaction kettle, a reduced-pressure distillation device and a vacuum filtration device which are connected in sequence. The ethylene glycol titanium production device system is characterized in that the reaction kettle is connected with three leaching towers through gas-phase pipelines, the bottom of each leaching tower is connected with a leaching groove, the leaching grooves are connected with the upper portions of the leaching towers through leaching pumps, and the leaching towers are further in series connection with a chimney. The lower portion of the reduced-pressure distillation device is connected with a buffer tank. The buffer tank is firstly connected with a plurality of parallelly connected clarifying tank groups which are connected with a material mixing tank, the material mixing tank is connected with a vacuum filter through a crystallization pump, and the vacuum filter is connected with the buffer tank. The ethylene glycol titanium production device system avoids ammonium chloride (NH4CL) generated through reaction in the prior art, post treatment of ethylene glycol titanium is easy, and produced waste acid can be sold. Ethylene glycol titanium products can be thoroughly washed in the clarifying tank groups in recycle mode.
Description
Technical field
The utility model relates to a kind of Titanium series catalyst production equipment, specifically is a kind of titanium ethylene glycolate production equipment system.
Background technology
Titanium ethylene glycolate is a kind of very promising polyester polycondensation catalyst.Titanium ethylene glycolate is by Ti (OCH
2CH
2O)
2For unitary one-dimensional long chain molecule constitutes, have definite crystalline structure, it not only in organic solvent, even in water the stability to hydrolysis of apparent altitude.
In the industry, titanium ethylene glycolate is that tetracol phenixin and anhydrous glycol reaction make, and can produce a large amount of HCl gas in the reaction process.In the prior art, it is in reaction unit, to pass through NH that HCl handles
3Gas is neutralized to neutrality, in subsequent handling, disposes NH then
4In addition, also there is halfway problem in Cl to the titanium ethylene glycolate solids wash in the prior art.
Summary of the invention
The utility model provides a kind of titanium ethylene glycolate production equipment system, and the HCl gas that its absorption reaction produces is processed spent acid, and repeatedly circulation cleaning filters, and it is good to make the titanium ethylene glycolate solid masses.
The concrete technical scheme that adopts of the utility model is:
A kind of titanium ethylene glycolate production equipment system; Comprise the reaction kettle, vacuum distillation apparatus and the vacuum apparatus that connect successively; It is characterized in that said reaction kettle connects three eluting columns with the gas phase pipeline, is connected with the drip washing groove at the bottom of each drip washing Tata; The drip washing groove is connected with eluting column top through the drip washing pump, and eluting column also is serially connected with chimney;
The vacuum distillation apparatus bottom is connected with buffer tank, and buffer tank at first connects the clarifying tank group of a plurality of parallel connections, and the clarifying tank group connects mixing tank for coating colors, and mixing tank for coating colors is connected with vacuum filter through the crystallization pump, and vacuum filter is connected with buffer tank.
For saving power cost and in mixing tank for coating colors, not staying the dead angle, said mixing tank for coating colors is obliquely installed, its lowest part be connected with vacuum filter through the crystallization pump.
For better reclaiming spent acid, the drip washing groove all is connected with the sour pond of storage.
The utility model has the advantages that:
1) NH that has avoided the prior art reaction to generate
4Cl, the titanium ethylene glycolate post-processed is simple, and the spent acid that makes can be sold in addition;
2) product can be in the clarifying tank group circulation cleaning repeatedly, washing is thoroughly.
