Example Embodiment

[0026] Example 1

[0027] Such as figure 1 As shown, the sprinkler of the present embodiment is applied to the elimination flue gas desulfurization includes the main passage 1 and an outer passage 3 that is disposed outside the main passage 1, and is provided with an inlet and injection port 7 at both ends of the main passage 1. The inlet and the injection port 7 are sequentially provided with a swirl guide fluid 2, a shrinkage section 4, a mixed port 6, provided on the outer passage 3, and the outer channel 3 passes through the mixed suction port 6 and the main channel. 1 Connect, the fluid in the main channel 1 and the outer channel 3 mixed with the mixed suction port 6 and discharged through the injection port 7.

[0028] In the present embodiment, the main passage 1 is mainly used in the circulation of main fluid (i.e., the main channel 1 has an inlet for mainstant entry and injection port 7, import, and The injection port 7 can be relatively disposed at both ends of the main ...

Abstract

The invention provides a spray head suitable for carbide slag flue gas desulfurization. The spray head comprises a main channel and an outer channel arranged outside the main channel in a surrounding mode, an inlet and a jet orifice are formed in the two ends of the main channel respectively, a rotational flow guide body, a contraction section, a throat pipe and a mixed suction inlet are sequentially arranged between the inlet and the jet orifice, the inlet is formed in the outer channel, and the outer channel is communicated with the main channel through the mixed suction inlet. The fluid in the main channel and the fluid in the outer channel are mixed at the mixing suction inlet and sprayed out through the spraying opening. The spray head can fully utilize the characteristics of high solubility and high alkalinity of carbide slag to form an alkaline slurry drop absorption area in the absorption section of the desulfurization tower, so that the aims of enhancing sulfur dioxide absorption, reducing liquid-gas ratio, saving energy consumption, improving desulfurization efficiency and the like are fulfilled; meanwhile, the spray head does not influence the pH value of desulfurization slurry in the desulfurization tower, so that the problems of calcium sulfate scaling blockage, slow oxidation of calcium sulfite and the like in the tower can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of flue gas desulfurization, in particular to a spray head suitable for carbide slag flue gas desulfurization. Background technique [0002] SO 2 It is one of the main pollutants in coal-fired flue gas. The wet desulfurization technology using lime or limestone as a desulfurizer is currently the most widely used flue gas desulfurization method, accounting for more than 80% of flue gas desulfurization. Limestone is the main desulfurization agent in wet desulfurization process. It comes from limestone mines and has a wide range of uses and huge demand. However, excessive mining of limestone will cause damage to the ecological environment. At the same time, the price of limestone will gradually increase under the condition of resource shortage. [0003] Carbide slag is an alkaline solid waste with low price. In addition, the main component of calcium carbide slag is calcium hydroxide, which has the advantages ...
