Description
Technical field
The present invention relates to a kind of adsorption tower, relate in particular to a kind of adsorbing tower with molecular sieve.
Background technology
Molecular sieve is a kind of alumino-silicate compound with cubic lattice, mainly connects to form spacious skeleton structure by sial by oxo bridge, has uniform duct, a lot of apertures and marshalling, hole that internal surface area is very large in structure. Contain in addition electricity price compared with the water of metal ion low and that ionic radius is larger and chemical combination state. Because hydrone loses continuously after heating, but crystal framework structure is constant, form the cavity that many sizes are identical, cavity has again the micropore that many diameters are identical to be connected, these small hole diameter are even, can be the inside to hole than the little Molecular Adsorption of channel diameter, and handle is than the large molecule exclusion that obtains in duct, thereby can be molecules different shape diameter, the molecule that polarity degree is different, the molecule that boiling point is different, the molecular separation that degree of saturation is different comes, there is the effect of " screening " molecule, therefore be called molecular sieve. At present molecular sieve is at chemical industry, electronics, and petrochemical industry, is widely used in the industry such as natural gas. Existing adsorbing tower with molecular sieve mostly is first vaporizing liquid upon adsorption, and to the Steam Heating after vaporization, the overheated gas of generation adsorbs by molecular sieve, thereby reaches the object of purification. After molecular sieve adsorption is saturated, the heat energy itself containing due to the overheated gas by molecular sieve is lower, can not make the moisture of absorption evaporate in time, and regenerating molecular sieve speed is slower, extends the production time, increases production cost, cannot meet actual production requirement.
Summary of the invention
The object of this invention is to provide the adsorbing tower with molecular sieve that regeneration rate is high.
The technical solution used in the present invention is:
A kind of adsorbing tower with molecular sieve, comprise cylindrical shell, in described cylindrical shell, be provided with the heat exchanger tube of multiple dense distribution of vertical placement, the upper and lower two ends of described cylindrical shell are provided with upper perforated plate and lower perforated plate, described upper perforated plate and lower perforated plate are provided with corresponding aperture for fixing heat exchanger tube, above described upper perforated plate, be provided with top cover, in the middle of described top cover, be provided with distillation gas import, described cylindrical shell top surrounding is provided with multiple steam inlets, described distillation gas import both sides are respectively equipped with temperature transmitter mouth and pressure transmitter mouth, below described lower perforated plate, be provided with bottom, described bottom is provided with discharging opening, described cylindrical shell bottom is provided with condensation-water drain.

Further, described cylindrical shell both sides are provided with journal stirrup.
Further, described steam inlet is 4, and distributes at same even circumferential.
Further, aperture is inner with the fine and closely woven silk screen filling of multilayer.
The beneficial effects of the utility model are:
1. simple in structure, effect is good, and being provided with temperature transmitter mouth and pressure transmitter mouth can monitor vapor (steam) temperature and pressure by temperature transmitter and pressure transmitter.
2. upper perforated plate and lower perforated plate are provided with corresponding aperture for fixing heat exchanger tube, and aperture is inner fills with the fine and closely woven silk screen of multilayer, has prevented that molecular sieve from being driven back and forth by high pressure draught.
