Description
Technical Field
The invention relates to an energy-saving continuous sulfur melting device and a process thereof, in particular to a continuous sulfur melting technology which is energy-saving and can improve the quality of liquid sulfur.
Background
The domestic liquid-phase oxidation-reduction desulfurization process achieves remarkable results after years of development, and in recent years, the process is industrially applied to northwest Tahe oil fields, victory clinical discs and southwest oil and gas fields. The by-product of the liquid-phase oxidation-reduction desulfurization process is sulfur paste containing about 60% of sulfur, and in order to obtain national commercial grade sulfur, the sulfur paste must be subjected to sulfur melting refining, the core equipment of sulfur melting is a sulfur melting kettle, and the sulfur melting kettle has two forms of an intermittent sulfur melting kettle and a continuous sulfur melting kettle, and the sulfur melting principle and the matching process are different, and the sulfur melting kettle has respective technical characteristics.
At present, the domestic sulfur refining process continues for decades by the traditional sulfur melting method, is widely applied in chemical fertilizer plants, is intermittent, and mainly comprises the following steps: and (3) loading the sulfur filter cake into an intermittent sulfur melting kettle from the top, sealing an inlet and an outlet, opening a valve of an air release pipe, and then opening a steam valve. Steam enters a jacket of the sulfur melting kettle and an inner heating coil respectively to start sulfur melting. As steam enters, the water in the filter cake is gradually vaporized and discharged through a gas discharge pipe. After the water in the sulfur filter cake is completely vaporized and discharged, the sulfur in the sulfur melting kettle is continuously heated until the sulfur is liquefied. The salt in the sulfur paste is basically concentrated in the melted sulfur, so that the purity of the sulfur is reduced, the moisture in the sulfur paste is completely discharged in a steam form, and the environment is severe and is not environment-friendly. The whole process flow is too simple, only one material valve with one inlet and one outlet is controlled to realize feeding, slag discharging and sulfur discharging, operators are required to operate all the time, the labor intensity is high, and the operators can be scalded due to careless operation. The intermittent sulfur melting is suitable for small-scale sulfur refining and is not suitable for the modernized large-scale sulfur melting refining process.
The prior continuous sulfur melting process is shown in figure 1: the sulfur slurry is pressurized by a pump and then is fed from the top of the sulfur melting kettle, a jacket is arranged outside the sulfur melting kettle, and steam is adopted for heating. Separating slurry in a sulfur melting kettle into two parts of clear liquid and sulfur paste, wherein the clear liquid flows out from a pipe orifice at the top of the side of the sulfur melting kettle, the temperature is 70-90 ℃, and the clear liquid is cooled and then sent to a slurry forming tank to be used as water for preparing sulfur filter cakes for cyclic utilization; the separated sulfur paste continues to descend and is further melted, and the melted liquid sulfur is continuously discharged from the bottom of the sulfur melting kettle and is sent to a liquid sulfur storage tank. The moisture of the sulfur paste in the continuous sulfur melting kettle does not need to be vaporized, only liquid is layered, no waste gas is discharged, most of the sulfur melting clear liquid is returned to the slurry forming tank for recycling, and the discharged waste liquid is only the moisture in the sulfur paste. The proper automatic sulfur discharge measure is set by combining the characteristic of continuous sulfur melting, the automatic operation of the sulfur melting system is really realized, and the requirement of a modern device is met. The salt in the sulfur paste is basically dissolved in the clear liquid and discharged, and the purity of the sulfur is high and can reach more than 98 percent. Compared with an intermittent sulfur melting kettle, the continuous sulfur melting kettle has the advantages of lower energy consumption, environmental protection and convenience for continuous operation.
The main defects of the existing continuous sulfur melting process are that 1, most of sulfur produced is qualified products, and the quality indexes of first-class products (the sulfur content is more than or equal to 99.50 percent, and the water content is less than or equal to 0.20 percent) cannot be achieved; 2. 1 ton of sulfur is produced and 1 ton of waste water is produced; 3. utilities provide low utilization of external heat.
