Embodiment Construction

[0035] Take the gypsum slurry foam produced during the flue gas desulfurization process of a certain power plant as an example. The main component of desulfurization gypsum is calcium sulfate dihydrate, and the moisture content of the gypsum foam is about 5%, which has certain adsorption and corrosion properties. After the gypsum slurry foam is collected, it is treated with the pulverizing system of the present invention.

[0036] Such as figure 1 and figure 2 As shown, the gypsum slurry foam pulverizing system includes a feeding unit, a pulverizing unit and a collecting unit; the feeding unit includes a foam collecting tank 1 and a feed tank 2 connected to the bottom side of the collecting tank; the pulverizing unit It includes a dehumidification drum 3 , a central cylinder 4 connected inside the dehumidification drum 3 , a transmission motor 5 connected to one end of the dehumidification drum 3 , a heating main pipe 9 connected to the end of the central cylinder 4 away fro...

Abstract

The invention discloses a gypsum slurry foam powdering system and a construction method thereof. The powdering system comprises a feeding unit, a powdering unit and a collection unit, wherein the feeding unit comprises a foam collection tank and a guide groove which is connected with the side surface of the bottom of the collection tank; the powdering unit comprises a dehumidification roller, a central cylinder which is connected inside the dehumidification roller in a penetration manner, a transmission motor which is connected with one end of the dehumidification roller, a heating mother tubewhich is connected with the central cylinder at one end far away from the transmission motor, and heating tubes which are connected with the central cylinder inside the dehumidification roller; and the collection unit comprises a scraper plate and a collector below the scraper plate. In construction, due to arrangement of the dehumidification roller and designing of heating inside the dehumidification roller, gypsum slurry foams can be dehydrated and powdered, and the powered gypsum slurry foams can be recycled and treated or reused through the collector; and with the effective combination ofrotation of the dehumidification roller and scraping of the scraper plate, the foams are easy to dehydrate, and can be conveniently recycled after being dehydrated into powder.

Description

technical field [0001] The invention relates to a gypsum desulfurization process, in particular to a gypsum slurry foam pulverizing system and a construction method thereof. Background technique [0002] At present, my country's environmental protection requirements for thermal power plants are becoming more and more stringent, and the emission standards of air pollutants in thermal power plants have been further improved. Therefore, the task of desulfurization and emission reduction faced by thermal power plants is becoming more and more severe. During the desulfurization process, in the circulation system of the desulfurization absorption tower, the design operation liquid level of the absorption tower is relatively high. If the flue gas carries a large amount of impurities into the desulfurization absorption tower, it will cause the gypsum slurry to foam or overflow, which is very easy to occur after the gypsum slurry is foamed. Flying bubbles or slurry are ejected from t...
