Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the following in conjunction with the attached Figure 1-7 And embodiment, the present invention is described in further detail. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] This embodiment provides a desulfurization wastewater treatment system, including a wastewater source connected by a wastewater delivery pipe, a high-pressure heating chamber 5, and an evaporation chamber 1. The top of the evaporation chamber 1 is provided with an air outlet, and the bottom end is provided with a salt leg. A salt slurry conveying pipe and a liquid inlet pipe are connected to the bottom of the salt leg.

[0030] After the desulfurization wastewater is initially treated, the pump is transported to the evaporation crystallization system including the high-pressure heating ch...

Abstract

The invention discloses a treatment system for desulfurization wastewater. The treatment system for desulfurization wastewater comprises a wastewater source communicated by a wastewater conveying pipe, a high-pressure heating chamber and an evaporation chamber, wherein an air outlet is formed in the top end of the evaporation chamber, a salt leg is arranged at the bottom end of the evaporation chamber, and a salt slurry conveying pipe and a liquid inlet pipe are connected to the bottom of the slat leg. In the application, a large pressure difference is set between the high-pressure heating chamber and the evaporation chamber, so that the pressure drops rapidly after desulfurization wastewater enters the evaporation chamber, and the evaporation speed is remarkably improved to achieve flashevaporation; the salt leg is arranged at the bottom of a crystallizer, and the salt leg has the functions of collecting salt, carrying out classification, washing, redissolving soluble impurities, transportation and the like, thereby being capable of improving the quality of the salt and reducing the energy consumption of the system; and a circulating pump is used, so that desulfurization wastewater and crystal salt are circulated between a heater and the crystallizer at high speed to scour the pipe wall of the heater so as to reduce scaling.

Description

technical field [0001] The invention relates to the technical field of desulfurization wastewater treatment, in particular to a desulfurization wastewater treatment system. Background technique [0002] The flue gas contains a large amount of acid gases such as sulfur dioxide, which seriously pollutes the environment. Therefore, before the flue gas is vented, it must undergo desulfurization treatment. However, desulfurization will produce a large amount of wastewater. Therefore, how to treat desulfurization wastewater can reduce environmental impact Pollution is also a very important issue. Contents of the invention [0003] The purpose of the present invention is to provide a desulfurization wastewater treatment system to solve the problems of large amount of desulfurization wastewater and serious environmental pollution. [0004] In order to solve the above-mentioned technical problems, the present invention adopts the following technical solutions: [0005] A desulfur...
