The regeneration tower 401 analyzes the reacted adsorbent into nitrogen oxides, the regenerated adsorbent is heated to be regenerated adsorbent by a regeneration heat source, the regenerated adsorbent is introduced into the adsorption tower 13 for recycling, the regeneration tower 401 is used for carrying out regeneration treatment on the adsorbent adsorbed with the nitrogen oxides, and the adsorbent treated by the regeneration tower 401 and the nitrogen oxides are mutually separated to obtain the nitrogen oxides and the regenerated adsorbent. For example, after the adsorbent in the adsorption tower 1360 is introduced into the regeneration tower 401, the regeneration tower 401 may analyze the reacted adsorbent to be nitrogen oxides, and at the same time, the adsorbent in the adsorption tower 13 is heated by a heat source to be a regenerated adsorbent, and the adsorbent in the adsorption tower 13 may be heated by a regenerated heat source to generate a regenerated adsorbent, or may be electrically heated to generate a regenerated adsorbent.

Thus, the technical defect that each nitrogen oxide discharge port needs to be provided with a set of adsorption and regeneration devices independently, such as a set of adsorption and regeneration devices respectively arranged in the factory area of each user can be overcome. In addition, the mechanism for realizing the removal of the nitrogen oxides by the denitration adsorbent regeneration and nitrogen oxide recovery system provided by the embodiment of the utility model can be divided into the following three modes, wherein the first mode is that the adsorption and regeneration process can realize the enrichment and collection of the nitrogen oxides in the flue gas, but cannot eliminate the nitrogen oxides, and the denitration adsorbent regeneration and nitrogen oxide recovery system provided by the embodiment of the utility model can eliminate the nitrogen oxides by adopting the mechanism of returning the nitrogen oxides to the furnace for reduction, so that the nitrogen oxides are changed into harmless N 2. The mechanism of nitrogen oxide returning reduction is mainly realized by a thermodynamic equilibrium mechanism of reversible reaction and two mechanisms of reduction of reducing groups in the furnace. The thermodynamic equilibrium mechanism of the reversible reaction is that after the nitrogen oxides return to the hearth, the reaction is inhibited from proceeding to the direction of nitrogen oxide generation; the reduction mechanism of the furnace reducing group refers to that nitrogen oxides are reduced into N 2 under the action of reducing groups such as CH, CH 2, CO and the like in the furnace. The second is a new idea that the denitration adsorbent regeneration and nitrogen oxide recovery system provided by the embodiment of the utility model can also promote centralized treatment of nitrogen oxides in a park, and can solve the problem that the recycling recovery of single-outlet nitrogen oxides dispersed at each user does not have economic benefit. The saturated adsorption materials are collected and intensively regenerated to obtain thousands or ten thousand tons of enriched nitrogen oxides each year, so that the enriched nitrogen oxides can be prepared into products such as nitric acid, nitrate and the like for use, and the scale of resource utilization is provided. Thirdly, the analyzed high-concentration nitrogen oxides, namely the enriched nitrogen oxides, are collected in a concentrated mode and then treated uniformly by adopting an SCR method.
The utility model provides a denitration adsorbent regeneration and nitrogen oxide recovery system, which is characterized in that a plurality of adsorption units 1 are used for respectively carrying out adsorption treatment on industrial waste gas discharged by a plurality of waste gas generating units 2 so as to respectively generate a plurality of saturated adsorption materials. The conveying system is respectively connected with the regeneration treatment unit 4 and the plurality of adsorption units 1, and conveys a plurality of saturated adsorption materials to the regeneration treatment unit 4, and the regeneration treatment unit 4 analyzes and treats the saturated adsorption materials into nitrogen oxides and heats the saturated adsorption materials into regenerated adsorbents. In the process of regenerating the denitration adsorbent and recovering the nitrogen oxides, only one centralized regeneration point is needed in the chemical industry park, and after the industrial waste gas exhausted by each waste gas generating unit 2 passes through the adsorption unit 1 to generate saturated adsorption materials, the saturated adsorption materials are uniformly transported to the regeneration treatment unit 4 positioned at the centralized regeneration point by the conveying system for regeneration. After the saturated adsorption materials are scattered and collected, the saturated adsorption materials are conveyed to a regeneration treatment unit for centralized treatment, so that enriched nitrogen oxides with higher quantity can be obtained, the scale of resource utilization is achieved, and the saturated adsorption materials can be provided for products such as nitric acid and nitrate to be used. Therefore, the method achieves the technical effects of decentralized collection and centralized treatment, is beneficial to reducing the cost, realizing the recycling and improving the economic benefit.
