Abstract
The utility model discloses a moving bed adsorption tower for exhaust gas purification. The adsorption tower is sequentially composed of a cooling section, an adsorption section and a desorption section from top to bottom. The adsorption tower is characterized in that the cooling section tower body is provided with a cooling water outlet and a cooling water inlet; a distributing plate is arranged inside an adsorption section tower body; a waste gas inlet and a purified gas outlet are arranged on the adsorption section tower body; and an intermediate recovery opening, a bottom recovery opening, a steam inlet and a steam outlet are arranged on the adsorption section tower body. An adsorbent can be cooled, desorbed and regenerated in a flowing manner inside different tower bodies; gas-solid mass transfer is greatly enhanced because of strong disturbance of fluid and solid; the superficial area of the adsorbent in unit volume is increased because of adopting small-particle adsorbent; gas-solid contact is optimized by solid fluidization; and the mass transfer rate of an interface is improved, so as to enhance the production capacity of equipment. The fluidized bed adopts the gas velocity which is much greater than that of a fixed bed, so that the equipment investment can be greatly reduced; the gas and the solid are in the fluidized state, so that temperature distribution of the bed layer can be even; and large-scale continuous production can be achieved.
Description
Technical field
The utility model relates to a kind of waste gas purification moving bed adsorption tower, belongs to the waste gas purification technical field.
Background technology
Waste gas purification usually adopts adsorbent to purify when processing, adsorbent equipment is the core of adsorption system, the industrial adsorbent equipment that uses is three major types altogether, be fixed bed, moving bed and fluid bed, wherein extensive with fixed bed applications, no matter but be which kind of adsorbent equipment, when carrying out the gas purification design, must consider basic demand.The ADSORPTION IN A FIXED BED system, it is that adsorbent is fixed on a certain position, carries out adsorption operations in its actionless situation.It mostly is cylindrical equipment, places adsorbent on the lattice plate of inner support or orifice plate, makes the gas of processing by it, and adsorbate is attracted on adsorbent.The application of fixed bed is more common.If only need the short-term flow of process air, so usually only need an adsorbent equipment, this will be so that the time enough interval to be arranged between adsorption cycle, in order to carry out the regeneration of adsorbent certainly.But owing to usually requiring pending gas continuous-flow, one or more devices that therefore must employing can operate in such a way.Be used for removing the prevailing adsorption system form of pollutant from air-flow, be comprised of many fixed bed devices, these devices carry out adsorption operations and regenerative operation sequentially, so that air-flow keeps continuously.Absorption needs continued operation, adsorbent can the carrying out in different vessels flow desorption and regeneration.
The utility model content
The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, a kind of waste gas purification moving bed adsorption tower is provided, adsorbent can be in different tower bodies carrying out flow cooling, desorption and regeneration, have that disposal ability is large, efficient is high, be easy to installation, maintenance, the adsorbent long service life, the characteristics of system's continued operation.
The purpose of this utility model is achieved through the following technical solutions: a kind of waste gas purification moving bed adsorption tower, by being comprised of cooling section, adsorption section and desorption section successively from top to bottom, it is characterized in that: described cooling section tower body arranges coolant outlet and cooling water inlet; Described adsorption section tower body inside arranges distribution plate, and the adsorption section tower body arranges exhaust gas inlet and purified gas outlet; In the middle of arranging, reclaims described desorption section tower body mouth, bottom recovery mouth, steam inlet and steam (vapor) outlet.
Described regenerator upper end is connected with charging aperture with pipeline, and regenerator lower end use pipeline is connected with connector.
Further, be provided with material level detector in the material bin below described desorption section.
The utility model operation principle: waste gas to be evolved enters adsorption section from exhaust gas inlet, the adsorption section tower body arranges exhaust gas inlet, waste gas is through distribution plate and adsorbent counter current contacting from top to down, and waste gas is adsorbed purification, and after purifying, gas is discharged from purified gas outlet.Adsorbent after absorption enters the desorption section, passes into steam from steam inlet adsorbent is regenerated, and the desorption product reclaims mouth and bottom and reclaims a mouthful discharge from the centre, and steam is discharged from steam (vapor) outlet.After desorption, adsorbent is raised device and rises to cooling section top and carry out coolingly, passes into cooling water from cooling water inlet, and cooling tube is cooling with adsorbent, and next adsorbent carries out again adsorption operations.In order further to reduce the content of adsorbate in adsorbent, controlled by discharge valve the part adsorbent is risen to regenerator, further complete desorption and regeneration.
In sum, the beneficial effects of the utility model are: the carrying out that adsorbent can be in different tower bodies flow cooling, desorption and regeneration; Due to the strong disturbance of fluid and solid, greatly strengthened the gas-solid mass transfer; Owing to adopting the granule adsorbent, make the long-pending increase of adsorbent surface in unit volume; The contact of gas-solid has been optimized in the fluidization of solid, has improved the mass transfer rate at interface, thereby has strengthened the production capacity of equipment, because fluid bed has adopted the gas speed more much bigger than fixed bed, thereby can greatly reduce equipment investment; Because gas and solid are in fluidized state together, bed temperature are evenly distributed, and can realize producing continuously on a large scale.
