Embodiment 1

[0047] This embodiment provides a gas processing tower, such as Figure 1 to Figure 8 shown, including:

[0048] tower body 1;

[0049] Packing layer 3, straddling the tower body 1, at least one layer is arranged, and its side walls are connected with the surrounding inner walls of the tower body 1;

[0050] The pipeline spraying system 4 is arranged inside the tower body 1, and it is equipped with a spray head 42 arranged towards the packing layer 3;

[0051] It is characterized in that the packing layer 3 includes a wire mesh layer and a number of bulk fillers packed inside the wire mesh layer, preferably spherical packing.

[0052] In the above-mentioned gas treatment tower, a packing layer 3 is arranged in the tower body 1. When the flue gas passes through the packing layer 3, it can fully contact with the spherical packing, effectively derotation and dispersing the swirling flue gas, and the mist entrained by the flue gas and The dust is effectively and quickly absorbe...

Embodiment 2

[0079] In this embodiment, the original baffle defogging system of the upper half of the non-amplified section flue gas ammonia method wet desulfurization tower with a diameter of 8 meters of a 3×75 ton / hour thermoelectric coal-fired boiler has been modified.

[0080] Among them, the numbers of different experimental conditions of the flue gas purification tower are 1#, 2#, 3#, 4#, 5#, 6#. Such as Figure 7 As shown, the packing layer of 1# has only one layer and is set at the cylindrical tower body. The inner diameter of the tower is 8 meters, and the diameter of the spherical packing is Φ50mm. To prevent clogging, 316L stainless steel wire mesh porous hollow body spherical packing is used. Such as Figure 8 As shown, 2#, 3#, 4#, 5#, and 6# have two layers of packing layers respectively, the inner diameter of the tower is 8 meters, the lower layer is a spherical packing layer filled with a height of 800mm, and the upper layer is a baffle with a height of 200mm7 , A spherica...

Abstract

The invention provides a gas processing tower and a gas processing system. Wherein, the gas treatment tower is used for gas purification or separation, including: a tower body; a packing layer, straddling the tower body, at least one layer is arranged, and its side walls are connected with the surrounding inner walls of the tower body; pipeline spraying The system is arranged inside the tower body and is used for flushing the packing layer; the packing layer includes a wire mesh layer and several spherical packing arranged inside the wire mesh layer. The gas treatment tower sets a packing layer in the tower body, so that when the flue gas passes through the packing layer, the packing layer can better realize the gas-liquid distribution, make them fully contact, and effectively racemize and disperse the swirling gas. The entrained mist and smoke are effectively and quickly absorbed and trapped by the spherical packing and the liquid film formed by it, so as to achieve the purpose of cleaning the flue gas and improve the efficiency of flue gas purification. At the same time, the flue gas is further purified by flushing the flue gas with the pipe spraying system.

Description

technical field [0001] The invention relates to the technical field of desulfurization, dust removal and fog removal, in particular to a gas processing tower and a gas processing system. Background technique [0002] Flue gas is a mixture of gas and soot, the gas includes water vapor, SO 2 , CO, CO 2 , NO X etc., the soot includes fuel ash, coal particles, and pyrolysis products. Flue gas is produced in thermal power, chemical industry, smelting and other fields, which is one of the main causes of air pollution. Therefore, it is very necessary to purify the flue gas. [0003] Taking boiler tail gas as an example, the common methods of dust removal for boiler tail gas include cloth bag dust removal, electric dust removal and electric bag composite dust removal. After dust removal, the flue gas passes through a desulfurization tower for wet desulfurization. The flue gas mist entrainment after wet desulfurization is serious. Even if the particulate matter in the flue gas t...
