Embodiment 1

[0093] like figure 1 As shown, a vertical liquid-phase catalytic disproportionation and destabilization and sulfur analysis system, the system includes a vertical catalytic disproportionation reaction chamber 1, a destabilization and desulfurization reaction device 2 and a sulfur-loaded activated carbon catalytic layer 3. Wherein, the upper end of the vertical catalytic disproportionation reaction chamber 1 is provided with a disproportionation liquid inlet 101 , and the lower end is provided with a disproportionation liquid discharge port 102 . The disproportionation liquid inlet 101 of the vertical catalytic disproportionation reaction chamber 1 is connected with a waste water delivery pipeline L1 containing bisulfite ions. The disproportionation liquid outlet 102 of the vertical catalytic disproportionation reaction chamber 1 communicates with the destabilization liquid inlet 201 of the destabilization sulfur analysis reaction device 2 . A filtrate discharge pipe L2 is co...

Embodiment 2

[0095] Repeat Example 1, such as figure 2 As shown, only the inner cavity of the destabilization reaction device 2 is divided into a destabilization reaction zone 203 , a buffer zone 204 and an overflow zone 205 by partitions. The destabilization reaction zone 203, the buffer zone 204 and the overflow zone 205 are connected in series in sequence. The destabilization liquid inlet 201 is arranged on the top of the destabilization reaction zone 203, the destabilization liquid outlet 202 is arranged at the bottom of the overflow zone 205, and the bottom of the destabilization reaction zone 203 and the buffer zone 204 together form a The lower end is a destabilizing discharge port 206 with a gradual necking structure.

Embodiment 3

[0097] Example 2 is repeated, except that the partitions include a first partition 207 and a second partition 208 . The first partition 207 is arranged between the destabilization reaction zone 203 and the buffer zone 204 . The second partition 208 is disposed between the buffer zone 204 and the overflow zone 205 .

Abstract

The invention discloses a vertical liquid-phase catalytic disproportionation and destabilization and analysis of sulfur wastewater treatment system and its treatment method. The system comprises a vertical catalytic disproportionation reaction chamber, a destabilization and analysis of sulfur reaction device and a sulfur-loaded activated carbon catalytic layer. The disproportionation liquid outlet of the vertical catalytic disproportionation reaction chamber is connected with the destabilization liquid inlet of the destabilization sulfur analysis reaction device. Several layers of sulfur-loaded activated carbon catalytic layers are arranged in series in the inner cavity of the vertical catalytic disproportionation reaction chamber from top to bottom. The system of the invention is simple in structure, easy to operate, low in cost, easy to popularize, has the prospect of large-scale application, and can realize the catalytic disproportionation reaction of bisulfite ion at about 50°C and recover sulfur resources. On the one hand, it reduces the salt content in the sulfur-rich gas washing wastewater, and on the other hand, it realizes the purpose of sulfur resource utilization. The consumption of liquid caustic soda is greatly reduced, and there is no secondary pollution, which has broad market prospects and economic benefits.

Description

technical field [0001] The invention relates to waste water treatment technology, in particular to a vertical liquid-phase catalytic disproportionation and sulfur destabilization analysis system and a treatment method thereof, and belongs to the technical fields of bisulfite-containing waste water treatment and sulfur resource recovery. Background technique [0002] Sulfur dioxide is one of the main air pollutants in my country, with an annual emission of nearly 20 million tons, causing serious waste of sulfur resources and air pollution such as acid rain and smog. With the increasingly stringent national environmental laws, regulations and standards, the realization of sulfur dioxide emission reduction and recovery has become a major issue that urgently needs breakthroughs in the field of environmental protection. Sulfur is an oxygen group elemental non-metallic solid, and is an important chemical raw material, widely used in the production of various chemical products, gun...
