Embodiment Construction

[0021] The specific embodiment of the present invention is as figure 1 shown.

[0022] In this embodiment, five layers of perforated grate plates are installed on the tank wall of the carbon disulfide recovery tank. On the tank wall of the carbon disulfide recovery tank, there are five layers of equal-height mounting brackets for installing porous grate plates; 4 brackets are installed on each layer, and the 4 brackets in the same layer are on the circumference of the recovery tank wall They are distributed at 90° each other.

[0023] The porous grate is a circular porous structure made of 1.2mm thick stainless steel sheet. The outer diameter of the porous grate is slightly smaller than the inner diameter of the carbon disulfide recovery tank. Ribs are set in the diameter direction of the two; for the convenience of installation, except for the uppermost porous grate plate, there are 4 installation gaps on the outer edge of each porous grate plate, and the installation gaps...

Abstract

The invention relates to a method for reducing leakage of carbon disulfide gas through a water seal layer, which is characterized in that on pot wall of a carbon disulfide recovery pot (2), multilayer porous grid plates (1) which are perpendicular to the pot wall are arranged; each layer of the porous grid plate is placed on a lug (4) which has equal height with each layer of pot wall of the carbon disulfide recovery pot, carbon disulfide gas passes through the multi-layer porous grids, delay cooling time of carbon disulfide in water is increased, bubbles of carbon disulfide formed in water are fragmented layer by layer during a rising process and are getting smaller for being liquefied, carbon disulfide gas leakage amount can be greatly reduced. According to the invention, multilayer porous grid plates are added in the water seal layer of the recovery pot, the total superficial area for contacting carbon disulfide gas and water can be greatly increased through bubbles fragmentation, cooling speed of the carbon disulfide gas is increased, conversion proportion of gaseous state carbon disulfide to liquid state carbon disulfide can be increased, carbon disulfide gas leakage can be greatly reduced, recovery rate of carbon disulfide is high, and pollution and hidden trouble due to carbon disulfide leakage can be reduced.

Description

[0001] technical field [0002] The invention relates to a method for reducing the leakage of carbon disulfide gas through a water seal layer, and belongs to the technical field of insoluble sulfur production technology. Background technique [0003] In the production process of insoluble sulfur, carbon disulfide plays an important role as an extractant. In order to reduce costs, the recovery of carbon disulfide cannot be underestimated. In the traditional process, the recovery of carbon disulfide is to use the evaporated carbon disulfide gas to pass through the lower temperature liquid carbon disulfide layer and the cooling water seal layer to be cooled to below 46.5 ° C to become a water-insoluble liquid, because the specific gravity of liquid carbon disulfide is greater than The specific gravity of water, the liquid carbon disulfide formed by the cooling of carbon disulfide gas will settle into the liquid carbon disulfide layer under the water and store it at the bott...
