Description
Technical Field
The utility model relates to the technical field of flue gas desulfurization by a catalytic method, in particular to a flue gas humidifying device for a flue gas desulfurization system by a catalytic method.
Background
The flue gas desulfurization technology by the catalytic method is a known desulfurization technology with application prospect, and the basic principle is as follows: sulfur dioxide, water and oxygen in the flue gas are adsorbed on the catalyst and react to generate sulfuric acid under the catalysis of active components. After the catalyst has been bound to some extent with sulfuric acid, the catalyst may be washed with a regeneration liquid (usually dilute sulfuric acid and/or water) to remove the bound sulfuric acid from the catalyst and release the catalyst sites. The used regenerated liquid can be reused as a byproduct (usually dilute sulfuric acid). Relevant references include: the state of the art and trend of flue gas desulfurization by the catalytic method are the congress of the annual academy of sciences of the academy of sciences of China, 2009, huang Pan and the like.
When the catalytic flue gas desulfurization technology is applied to practical engineering, a special catalytic flue gas desulfurization tower and a desulfurization reactor arranged in the catalytic flue gas desulfurization tower are needed. The applicant of the present application provides a catalytic flue gas desulfurization device in the patent document with publication number CN214764545U, wherein a desulfurization reactor is provided with an air inlet, an air outlet, a liquid outlet and a catalyst filling space in the desulfurization reactor, and a spray device for washing and regenerating the catalyst is arranged on the desulfurization reactor; and during desulfurization, the flue gas enters the desulfurization reactor from the air inlet, is discharged from the exhaust port after being desulfurized by the catalyst, sulfur dioxide in the flue gas reacts on the catalyst to form sulfuric acid when passing through the catalyst, and the sulfuric acid enters the regeneration liquid sprayed on the catalyst and is discharged from the liquid discharge port when the catalyst is washed and regenerated.
The air inlet needs to be connected with an air inlet main pipe (belonging to a flue gas conveying pipeline to be desulfurized). In general, because water is needed to exist in the flue gas during the flue gas desulfurization by the catalytic method, a steam humidifying system is also arranged on a flue gas conveying pipeline to be desulfurized at present. The flue gas to be desulfurized is humidified by adopting the water vapor, firstly, the influence of the water vapor on the flue gas temperature is small because the flue gas temperature to be desulfurized is high, and secondly, the water vapor is easy to be uniformly mixed with the flue gas, so that the subsequent desulfurization effect is ensured. However, actual operation finds that because the steam depends on centralized supply of chemical manufacturers, because the condition of the chemical production site is complex, the abnormal hidden danger that the steam cannot be timely supplied exists, and if the steam cannot be supplied, the normal operation of the flue gas desulfurization tower of the catalytic method can be influenced.
