Abstract
The invention relates to a molecular sieve adsorption tower, which comprises a tower shell (1), an inlet (2) and an outlet (3) on the tower shell, and an adsorption material molecular sieve (4) in the tower shell (1), and is characterized in that a heater (5) is arranged in the molecular sieve adsorption tower. Compared with the existing molecular sieve adsorption tower, the molecular sieve adsorption tower has low requirement on the purity of raw material fluid (such as moisture and oil content in air), so that the operation cost is low, and meanwhile, the molecular sieve of the adsorption material can be dried and regenerated in the tower, so that the service life of the molecular sieve is greatly prolonged.
Description
The present invention relates to a kind of adsorbing tower with molecular sieve, particularly a kind of adsorbing tower with molecular sieve that heater is arranged.
In the adsorbing tower with molecular sieve field, there is not heater in the existing adsorbing tower with molecular sieve, most arts demands carry out degree of depth preliminary treatment to material flow, in omnibus control system technology, need raw air is carried out the cold dried and oil removing of the degree of depth, thereby its operating cost height; Simultaneously its desorption and regeneration process is used product fluid more, and as using oxygen backwash in the depressurization desorption process of producing in the omnibus control system technology, thereby the degree of depth of regeneration is not enough, and the life-span of its molecular sieve is shorter.
The object of the present invention is to provide a kind of adsorbing tower with molecular sieve of built-in heater, improve the temperature of material flow in process of production, to reduce the preliminary treatment degree of depth material flow; And periodically be heated to the full regeneration temperature of molecular sieve, to molecular sieve holomorphosis, significantly to prolong the molecular sieve life-span.
Adsorbing tower with molecular sieve of the present invention, comprise tower shell (1) and on import (2), the interior sorbing material molecular sieve (4) of outlet (3) and tower shell (1), it is characterized in that being provided with in the described adsorbing tower with molecular sieve heater (5).
Described tower internal heater (5) can be the hot device of vapour, electric heater etc., preferred electric heater.
Described tower internal heater (5) is equipped with temperature control function.
Below in conjunction with description of drawings the present invention, it is a preferred version of the present invention, does not limit the present invention, and scope of the present invention is defined by the claims.
Fig. 1 is the stereo dissected figure of adsorbing tower with molecular sieve of the present invention, comprise tower shell (1) and on import (2), the interior sorbing material molecular sieve (4) of outlet (3) and tower shell (1), it is characterized in that being provided with in the described adsorbing tower with molecular sieve heater (5).
Fig. 2 is according to adsorbing tower with molecular sieve of the present invention, the schematic diagram of equipment THE PRESSURE SWING ADSORPTION OXYGEN GENERATING DEVICE embodiment.
(6) are that heater (5) power supply source and temperature control equipment, (7) (8) (9) (10) (11) (12) are electromagnetic valves among the figure, and these valves are communicated with by pipeline, and (13) are that compression raw air, (14) are that product oxygen, (15) are the discharging nitrogen-rich air.
When equipment is started working, heater (5) starts heating by power supply and temperature control equipment (6), valve (11) is opened, valve (10) cuts out, raw air (13) flows in the jar of the left side, when raw air (13) passes through molecular sieve (4), nitrogen is attracted on the molecular sieve (4), remaining oxygen is conveyed into air accumulator (16) by the valve of opening (12), when nitrogen adsorption was saturated in the jar of the left side, valve (8) was opened, and valve (9) is closed, air is introduced in the jar of the right, repeats the process of left side jar; Valve on the jar of the left side (11) is closed, and valve (10) is opened and the atmosphere conducting, and step-down discharges the nitrogen that is adsorbed, and opens valve (12) flushing molecular sieve (4) simultaneously, and nitrogen-rich air (15) is through valve (10) emptying; When the right jar absorption is saturated, repeat the process of left side jar again; Through certain production cycle, when molecular sieve (4) absorption usefulness reduces, heater (5) is controlled in the full regeneration temperature by power supply source and temperature control equipment (6), make molecular sieve (4) holomorphosis; So move in circles, produce the oxygen that needs continuously.
Compare with existing adsorbing tower with molecular sieve, adsorbing tower with molecular sieve of the present invention is to material flow Purity (such as airborne moisture content, oil content) requires low, thereby operating cost is low; Simultaneously absorption The material molecule sieve can be dried regeneration in tower, thereby the molecular sieve life-span significantly prolongs.
Claims (3)
1. adsorbing tower with molecular sieve, comprise tower shell (1) and on import (2), outlet (3) and the interior sorbing material molecular sieve (4) of tower shell (1), it is characterized in that being provided with in the described adsorbing tower with molecular sieve heater (5).
2. the heater (5) in the adsorbing tower with molecular sieve of claim 1, the described tower of its feature can be the hot device of vapour, electric heater etc., preferred electric heater.
3. the adsorbing tower with molecular sieve of claim 1 is characterized in that the heater (5) in the described tower is equipped with temperature control function.
