Description

Waste gas adsorption tank

Technical Field

The utility model relates to a waste gas treatment technical field especially relates to a waste gas adsorbs case.

Background

For large-air-quantity low-concentration VOCs waste gas, adsorption concentration and thermal oxidation (or catalysis) are carried out in the mainstream treatment process at present, wherein the adsorption concentration is divided into rotating wheel adsorption concentration, fixed bed adsorption concentration, moving bed adsorption concentration and the like. After the fixed bed is concentrated and is adsorbed and saturated for a certain time (generally days or even weeks), desorption regeneration is needed, the desorption adopts hot gas desorption (which can be water vapor, hot nitrogen, hot air and the like), and the hot gas desorption gas quantity is far smaller than the adsorption gas quantity and generally less than one tenth of the adsorption gas quantity in consideration of practical frequency and investment cost reduction.

In order to ensure the adsorption repairing effect, the fixed bed adsorption box is designed according to the adsorption gas amount during the design, the gas is distributed on the windward side of the adsorption bed more uniformly, and the gas uniformly passes through the adsorption bed layer. Because the hot gas flow is below one tenth of the adsorbed gas volume during desorption, the resistance is low, and desorption steam can not evenly distributed, and the velocity of flow is high near the air inlet, and the velocity of flow is low far away from the air inlet for adsorbent bed desorption effect is poor, and adsorbent bed fails to regenerate completely, reduces the adsorption capacity when adsorbing once more, and long-term use can lead to discharging and exceeds standard.

Detailed Description

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the embodiments will be briefly described below. It is obvious that the drawings in the following description are only some embodiments of the invention, and that for a person skilled in the art, other drawings can be derived from them without inventive effort.

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments, which are not described herein in detail, but the present invention is not limited to the following embodiments.

With reference to fig. 1 and 2, the utility model provides a waste gas adsorption tank, including box 1, box 1 middle section is filled with adsorption material 2. The adsorbent 2 may be a material having an adsorbing ability, such as granular activated carbon, honeycomb activated carbon, or honeycomb zeolite.

In the present embodiment, a first chamber 3 and a second chamber 4 are respectively arranged between an adsorbing material 2 and the box body 1, the adsorbing material 2 has a plurality of partitions to divide the adsorbing material 2 into a plurality of regions, a first baffle 6 and a second baffle 7 hinged to the inner wall of the box body 1 are arranged in the first chamber 3, a third baffle 8 and a fourth baffle 9 hinged to the inner wall of the box body 1 are arranged in the second chamber 4, a first connecting flange 31 is arranged at the first chamber 3, a second connecting flange 41 is arranged at the second chamber 4, and the first flange 31 and the second flange 41 are connected with an external pipeline. And the first coupling flange 31 and the second coupling flange 41 are provided on opposite side walls of the case 1.

According to an embodiment of the present invention, the adsorbing material 2 is provided with a first partition 2a, a second partition 2b, a third partition 2c and a fourth partition 2d at equal intervals, and the adsorbing material 2 is divided into a first area 21, a second area 22, a third area 23, a fourth area 24 and a fifth area 25. And the first shutter 6, the second shutter 7, the third shutter 8, and the fourth shutter 9 each have both an open state and a closed state. When the first baffle 6, the second baffle 7, the third baffle 8 and the fourth baffle 9 are in a closed state, the first baffle 6 is positioned on the right side of the second partition board 2b and is in lap joint with the second partition board 2b, the second baffle 7 is positioned on the right side of the fourth partition board 2d and is in lap joint with the fourth partition board 2d, the third baffle 8 is positioned on the right side of the first partition board 2a and is in lap joint with the first partition board 2a, and the fourth baffle 9 is positioned on the right side of the third partition board 2c and is in lap joint with the third partition board 2 c.
