| titleOfInvention | Device and method for preparing hydrogen chloride by using sulfur-based compound fertilizer waste acid |
| abstract | The invention belongs to a device and a method for preparing hydrogen chloride by using sulfur-based compound fertilizer waste acid. The device comprises a hydrogen chloride gas pipeline and a hydrogen chloride recovery storage tank in a sulfur-based compound fertilizer absorption working section, wherein the hydrogen chloride gas pipeline is communicated with an inlet at the middle lower part of a filler absorption tower, the upper part of the filler absorption tower is provided with a sulfuric acid inlet connected with a concentrated sulfuric acid storage tank, and a gas phase outlet at the top of the filler absorption tower is connected with the hydrogen chloride recovery storage tank through an acid mist collector and a hydrogen chloride drying and purifying unit; the lower part of the filler absorption tower is provided with a sulfuric acid circulation port and a sulfuric acid discharge port, a tee joint is arranged between the concentrated sulfuric acid storage tank and the sulfuric acid inlet, and the third end of the tee joint is communicated with the sulfuric acid circulation port through a concentrated acid heat exchanger and a concentrated sulfuric acid pump; the sulfuric acid discharge port is connected with a potassium bisulfate reaction tank. The method has the advantages of simple structure, reasonable flow design, simple and convenient operation and effective improvement of the added value of the hydrogen chloride gas on the premise of reducing the production cost. |
