Embodiment Construction

[0018] The present invention uses a sulfur paste atmospheric pressure continuous sulfur melter to melt sulfur.

[0019] ① The structure of sulfur paste atmospheric pressure continuous sulfur melter (hereinafter referred to as sulfur melter):

[0020] The structure of the sulfur melter is attached figure 1 As shown, it is mainly composed of a screw feeding device 1, a sulfur melting tank 9, an environmental protection cover 8 and a steam heating coil 2.

[0021] The screw feeding device 1 is composed of a hopper 26, a feeding pipe 27 with a propeller rotating shaft and a supporting motor 28. The hopper 26 is arranged on the feeding pipe 27 for feeding materials. The feeding pipe 27 is also provided with a feeding port 29 , The motor 28 is connected with the propeller rotating shaft through a shaft coupling 30 . Sulfur-melting tank 9 is a rectangular container welded by stainless steel plates, and the container mouth surface is welded with sealing ring, which can be sealed but...

Abstract

The invention belongs to the technical field of sulfur melting of coal gas desulfurization sulfur paste, and particularly relates to a normal-pressure continuous sulfur melting method for sulfur paste. According to the method, sulfur paste is continuously fed into a sulfur melting tank by a propeller-propelled feeding device under normal pressure, liquid sulfur with a certain depth is always kept in the sulfur melting tank, and the temperature of the liquid sulfur is always kept at 140-150 DEG C; the liquid sulfur is used as a heating medium to directly heat the sulfur paste; sulfur in the sulfur paste is molten into liquid and then enters the liquid sulfur, and the liquid sulfur is heated by a steam coil pipe arranged in the tank; heat source steam is fed into the steam coil pipe for heat supply; the sulfur melting tank is provided with a liquid sulfur outflow valve, and the outflow speed of liquid sulfur is controlled through the valve; and waste gas generated by sulfur melting is subjected to environment-friendly treatment by a condenser and a spray tower. The method has the advantages of low energy consumption, simplicity in operation, safety and environment friendliness.

Description

technical field [0001] The invention belongs to the technical field of sulfur melting sulfur paste for gas desulfurization, in particular to a continuous sulfur melting method for sulfur paste at normal pressure. Background technique [0002] Introduction to sulfur paste: desulfurization of coking plant or nitrogen fertilizer plant gas to obtain a desulfurization liquid with a sulfur content of about 5%, which is called sulfur foam. The sulfur foam is filtered through the filter equipment, and the filtrate is returned to the desulfurization system, and the sulfur-containing material with a high sulfur content is obtained through filtration, which is called sulfur paste. The sulfur content of sulfur paste depends on the filter equipment. In recent years, the sulfur paste obtained by the centrifuge filtration process has a sulfur content as high as 90%. [0003] The traditional process of melting sulfur for sulfur paste is the intermittent sulfur melting method. Put a certa...
