Abstract

A DEVICE FOR COAL-SULFUR MELTING, containing a housing, inside which are a tubular heater and a movably fixed lattice tank, a conical i bottom, a pipe for charging lump sulfur and a pipe for draining liquid sulfur, characterized in that, in order to intensify the process by increasing the degree the use of sulfur, a pipe for draining liquid sulfur is located above the tubular heater installed vertically along the periphery of the housing at a distance of 4-12D from the wall of the housing with a pipe spacing of 0.20, 5ЛЗ, where P is the diameter housing.

Description

BUT

The invention relates to a structure for melting sulfur prior to burning and subsequent processing to sulfuric acid, and can be used in the mineral fertilizer industry.

The purpose of the invention is to intensify the process by increasing the degree of sulfur utilization.

Figure 1 presents the diagram of the apparatus; figure 2 - section aa in figure 1.

The apparatus consists of a cylindrical or rectangular case with a conical bottom 2. In the lid of the apparatus in the center there is a branch pipe 3 of lump sulfur. Bottom in the conical bottom 2 is provided a pipe 4 unloading sludge. In the upper part of the apparatus, a pipe 5 of liquid sulfur discharge is installed, which is located above the upper edge of tubular heaters 6, but below the upper edge of the movable lattice tank 7. Tubular heaters 6 are installed vertically along the periphery of the housing 1. At a distance of 4-12D from the wall of the housing pipe spacing of 0.2-0.5D, where) is the diameter of the body. At the bottom of the space limited by tubing by heaters there is a movable (removable) lattice capacity 7. A emergency connection of 8 liquid sulfur is installed below the conical part of the apparatus at the level (or below), the lower edge of the tubular heaters and the movable, lattice capacity.

The operation of the apparatus for melting lump sulfur is as follows.

Komovoy sulfur through pipe 3 is loaded in the apparatus, in which a movable lattice capacity 7 is lowered by a telpher. Komol sulfur, as more heavy, goes down and goes into capacity 7. Melting of lump sulfur occurs due to the accumulated heat of molten sulfur, i.e. . heat from the tubular heaters 6 is transferred through a layer of molten sulfur to lump sulfur. New batches of lump sulfur displace molten sulfur, which, in addition to the passage between tubular heaters 6, is additionally heated. The amount of molten sulfur increases, and excess of it flows through the pipe 5 of the liquid sulfur discharge. Fine ash impurities sink into the conical bottom 2 and periodically, as they accumulate,

5 sludge is discharged through the bottom nozzle 4. Periodically, the movable (removable) lattice tank 7 is also cleaned. Sulfur from this tank flows out, and foreign bodies trapped with lump sulfur are raised by the hoist upwards and discharged. The cleaned tank 7 is again lowered into the machine. The adjustment of the lump sulfur loading is carried out according to the temperature of the molten sulfur. With a lower 120-125 ° C load temperature to

ka sulfur ceases, and when you lift

135-145 - resumes.
