Embodiment Construction

[0047] refer to Figure 1 to Figure 4 An example of the present invention will be described.

[0048] The dry exhaust gas treatment device 1 of this embodiment, such as figure 1 As shown, it has an adsorption tower 2, a regeneration tower 3, a first conveying channel 5A and a second conveying channel 5B connecting the adsorption tower 2 and the regeneration tower 3 and transporting the adsorbent, and a closed lock-type channel connected to the upper and lower ends of the regeneration tower 3. A hopper 6 and a cleaning tower 7 for cleaning the desorption gas G containing the desorbed product desorbed from the adsorbent.

[0049] The adsorption tower 2 is a device for adsorbing and removing various substances such as SOx (sulfur oxide) in gas using an adsorbent (for example, carbon adsorbent, alumina adsorbent, silica adsorbent, etc.). The adsorption tower 2 is provided with a waste gas inlet 8 for introducing waste gas, an adsorption tower body 9 in contact with the adsorbent...

Abstract

A regeneration column which comprises: a regeneration column main body (11) having a long trunk; and desorbed-gas discharge paths (15) through which a desorbed gas is discharged. The main body (11) comprises: a heating part (26) which heats an adsorbent; a separation part (25) which separates a desorbable substance as a desorbed gas from the heated adsorbent; and a cooling part (27) which cools the adsorbent from which the desorbable substance has been desorbed by heating, the parts (26), (25), and (27) having been communicatively disposed in one direction and the heating part (26) and the cooling part (27) having approximately the same sectional outer diameter. The separation part (25) comprises an inner barrel part (30) and a flow velocity reduction part (31) which reduces the flow velocity of the desorbed gas. The desorbed-gas discharge paths (15) are apart from each other and connected to the downstream side of the flow velocity reduction part (31).

Description

technical field [0001] The invention relates to a regeneration tower and a dry waste gas treatment device. Background technique [0002] As a device for treating exhaust gas discharged from boilers, incinerators, and sintering furnaces, it is known that the exhaust gas is brought into contact with an adsorbent introduced into an adsorption tower to remove SO X (sulfur oxides), NO X A dry exhaust gas treatment device for various harmful substances in exhaust gas such as nitrogen oxides. [0003] Examples of the adsorbent include carbon adsorbents, alumina adsorbents, silica adsorbents, etc., but carbon adsorbents are more excellent because they can be treated at relatively low temperatures and can remove various harmful substances at the same time. Examples of the carbon adsorbent include activated carbon, activated coke, activated coke, and the like, and particularly preferred are granulated granular adsorbents of about 0.5 to 4 cm in size, and these adsorbents are known. ...
