Description

A kind of Novel flue gas desulfuring and denitrifying apparatus

Technical field

The utility model belongs to fume treatment field, is related to adsorbent equipment technology, and especially a kind of Novel flue gas desulfurization is de- Nitre device.

Background technique

In industrial operation, we often encounter this basic operation of absorption, especially carry out at polluted gas now The major way of reason is the method for activated carbon adsorption, desulphurization denitration granular absorption, will inevitably be inhaled using adsorption column Attached polluted gas, however the problem as adsorption operations maximum is exactly discontinuity, is adsorption column using a period of time Afterwards, it always to recoil, the substance of absorption be washed from into adsorption column, so that adsorbent reactivation.This defect will be so that absorption behaviour The operation for needing that a large amount of manpower and material resources is spent to carry out these adsorbent reactivations.

Adsorption process can be divided into two stages, the first stage be adsorbate from primary fluid flow by around absorbent particles to The outer surface absorption occurred after particle surface, second stage is adsorption molecule is unadsorbed from particle exterior surface and enters particle Internal inner surface absorption.Molecular Adsorption process presses first outer surface absorption, then the sequence of inner surface absorption carries out, desorption (desorption Or regeneration) Shi Zewei inversely carries out.During practical adsorption applications, influence adsorption effect principal element have temperature, pressure, Flow velocity, height/diameter ratio of adsorption column of fluid etc..The structure of adsorption column designs the flow velocity to fluid in adsorption process, adsorption column Height/diameter ratio has direct influence, is to guarantee adsorption effect in one timing of amount of adsorbent, the height of adsorption column has a minimum Value.Adsorption column is too low, and gas or liquid then just change, and flow out quickly from outlet, adsorb in this way upon leading into adsorption column The adsorption capacity very little of agent is zero, cannot achieve the adsorbing separation of fluid.If reducing the sectional area of adsorption column, height increases Add, raising adsorption capacity is advantageous in this way, but fluid flow rate increases, the residence time of gas or liquid in adsorption column Reduce, after decreasing below adsorption time, adsorption capacity then can sharply decline.Therefore, the design of adsorption column should select rationally Height/diameter ratio, to reach optimal adsorption effect.Based on the above situation, adsorption column generally all has certain altitude, so that Adsorption separation device volume is big.Ratio of height to diameter is larger in the prior art, and especially in field of waste water treatment, the length of adsorption column is general Between 1.5-2 meters, so long pillar is all and its inconvenient in transport, installation, filler, discharging, it would be highly desirable to solve.
