Vertical shell and tube cooler for cooling sulfur dioxide gas

Abstract

The invention discloses a vertical shell and tube cooler for cooling sulfur dioxide gas. The vertical shell and tube cooler is characterized by comprising a preparing chamber, a heat exchange pipe, a water tank, a slag settling chamber and a mixing chamber, wherein the slag settling chamber and the mixing chamber are arranged below the water tank; an inlet of the preparing chamber is connected with the superior sulfur dioxide output end, and while an outlet of the preparing chamber is connected to the inlet of the slag settling chamber by the heat exchange pipe passing through the water tank, so as to form a first cooling circuit structure; the outlet of the slag settling chamber passes through the water tank to be connected to the inlet of the mixing chamber; the outlet of the mixing chamber is connected to the inferior sulfur dioxide input end to form a second cooling circuit structure; a water inlet and a water outlet are formed in the water tank and are respectively connected with cooling water and a draining pipe. According to the vertical shell and tube cooler adopting the vertical structure, high-temperature gas is cooled twice by the water tank; the slag settling chamber is arranged below the water tank and enables solid sulfur produced by cooling superior sulfur to be settled, and thus the purpose of filtering solid sulfur is reached; the vertical shell and tube cooler has the beneficial effects that the cooling effect is improved, the water consumption is decreased, and the pipeline is avoided blocking.

Description

technical field [0001] The invention relates to a cooler, which refers to a vertical tubular cooler used for reducing the temperature of sulfur gas, and belongs to the technical field of sugar making equipment. Background technique [0002] In the sugar industry, the cooler is widely used, and it is an important equipment for cooling the sulfur dioxide gas used for sulfur fumigation of cane juice. At present, the sugar factory adopts the traditional horizontal water tank sulfur gas cooler, and the sulfur gas pipe is divided into upper and lower layers in the water tank in the shape of a serpentine tube. When the high-temperature sulfur dioxide gas circulating in the pipe passes through the water tank, it is exothermicly cooled by the circulating cooling water in the water tank, and the opening of the cold water valve is judged and controlled according to the temperature of the sulfur gas at the outlet of the cooler. However, the traditional horizontal water tank sulfur gas ...
