Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
Further, although the terms used in the present invention are selected from publicly known and used terms, some of the terms mentioned in the description of the present invention may be selected by the applicant at his or her discretion, the detailed meanings of which are described in relevant parts of the description herein.
Furthermore, it is required that the present invention is understood, not simply by the actual terms used but by the meaning of each term lying within.
FIG. 1 is a schematic diagram of the structure of a quenching device for producing insoluble sulfur according to the present invention.
As shown in FIG. 1, the invention discloses a quenching device for producing insoluble sulfur, which comprises a quenching device base 10, a quenching device gland 20 and a quenching device outlet expanding pipe 30, wherein the quenching device gland 20 is fixedly connected on the quenching device base 10. Preferably, the quench base 10 and the quench gland 20 are connected by bolts 40 and nuts 50.
The quench gland 20 is provided with a plurality of conical surfaces 21 to form a quench liquid cavity a, and in this embodiment, the quench gland 20 is provided with two conical surfaces 21 (as shown in fig. 1). Of course, the two conical surfaces 21 are only examples, and the number of the conical surfaces 21 is not limited in practice and is determined according to actual working conditions. In addition, the structure on the quenching press cover 20 is not limited to providing the conical surface 21, and this is only an example, and the conical surface 21 may be replaced by a structure with another shape, which is determined according to the actual working condition. A quenching liquid introducing pipe 22 is arranged on the side wall surface of the quenching device gland 20, and the quenching liquid introducing pipe 22 is communicated with the quenching liquid cavity a, so that fluid passes through the gap of the cone surface 21 to form a high-pressure annular cone liquid surface. A feed flange 23 is provided at the end of the quench liquid introduction pipe 22. The angle of the cone face 21 is preferably 45-75 deg., preferably larger and smaller. The quenching liquid introduction pipe 22 is inclined at the same angle as the quenching apparatus outlet enlarged pipe 30.
The quenching press cover 20 is also provided with a quenching material feeding pipe 24, the central part of the quenching device base 10 is provided with an expansion cavity 11, and the quenching liquid cavity a and the quenching material feeding pipe 24 are communicated with the expansion cavity 11. The quencher outlet-enlarging tube 30 is installed at the bottom end of the quencher base 10, communicating with the expansion chamber 11.
Preferably, a seal face gasket 60 is disposed between the quench gland 20 and the quench base 10. The thickness of the sealing gasket is 0.5-5 mm. The clearance between the quench base 10 and the conical surface 21 of the quench gland 20 is adjusted by adjusting the thickness of the seal face gasket 60 between the quench base 10 and the quench gland 20. The jet speed of the quenching liquid can be controlled by adjusting the size of the gap, so that the shearing and contact effects of the two substances are controlled.
Meanwhile, the pressure of the expansion cavity is controlled, so that the quenching effect and the particle size of the solid material are influenced. The smaller the expansion pressure, the larger the particles formed, but there is a limit that is so small that they are liable to cause clogging of the nozzle, not only of the type in which they are formed. The pressure in the expansion chamber is preferably in the range of 0.5-1.3 MPa. The pressure is lower than 0.5MPa, the shearing force cannot be reached, and particles cannot be formed, so that the nozzle is blocked. The pressure is higher than 1.3MPa, the annular gap is too small, the processing difficulty is larger, and the annular gap is easily blocked by foreign matters to cause bias flow. The larger the gap, the smaller the pressure, the smaller the flow velocity, and the smaller the shear force. The smaller the pressure, the larger the particles formed.
Further preferably, the expansion chamber 11 is tapered from top to bottom. An equipment connecting flange 12 is arranged at the lower end closing-in part of the expansion cavity 11 and used for being connected with quenching equipment, and the lower end closing-in part of the expansion cavity 11 is connected with the quenching device outlet expanded pipe 30.
According to the structural description, the quenching device for producing insoluble sulfur mainly depends on the fluid from the quenching liquid inlet pipe 22 to form a high-pressure annular cone liquid level through the gap of the cone surface, and the high-pressure annular cone liquid level is in continuous contact with the gas-phase fluid from the quenching material feeding pipe 24 to form uniform solid-liquid mixed material to be sprayed into the expansion cavity. A liquid seal is formed at the mouth of the expansion chamber 11 and is ultimately injected into the quenching apparatus at an angle from the quench outlet enlarged tube 30 by virtue of the pressure within the chamber. The angle is preferably 5-30 degrees, and the design aims to ensure the slow expansion process of the materials from the high-pressure area to the low-pressure area, ensure the spraying effect, better pulverize and control the particle size of the pulverized materials. Meanwhile, the material is sprayed into the quenching equipment at a certain angle, so that the phenomenon that the material is adhered to the inner wall of the equipment due to splashing of the material is avoided.
More specifically, the quenching liquid is conveyed to the quencher by an external conveying device, and enters the quencher through the quenching liquid introduction pipe 22. And an annular cone liquid level is formed in a gap between the quenching device base 10 and the cone surface of the quenching device upper gland 20 and sprayed into the expansion cavity 11, and the annular cone liquid level is fully mixed and quenched with the gas-phase material from the quenching material feeding pipe 24 to form a solid-liquid mixed material.
Then, a certain liquid seal is formed at the closing-in of the expansion cavity 11, and finally the liquid seal is sprayed into quenching equipment through the quenching device outlet expanding pipe 30 under a certain pressure to complete the whole quenching process, and finally granular materials are formed.
In addition, the change of the scheme can be realized by adjusting the gap between the quenching device base and the conical surface of the quenching device gland, and the whole structure does not change greatly. The length of the bell mouth at the lower part is related to the diameter of the tank body and the control height of the liquid level, the distance between the outlet of the expansion pipe and the liquid level is controlled to be at least more than 50cm, and the materials are further expanded and dispersed after coming out. If the temperature is too low, the liquid level material is easy to splash to the expansion pipe to form up-down backflushing. Meanwhile, the liquid level is not suitable to be too low, and the sprayed materials completely enter the liquid level below and do not directly contact the inner wall of the equipment according to the spraying expansion condition of the materials. The height adjustment may shorten the enlarged tube length by continuous physical cutting.
In conclusion, the quenching device for producing the insoluble sulfur is used for quenching the gas-phase material and the liquid-phase material together by spraying, so as to form a granular or powdery material. Because the contact specific surface area of the two substances is increased, the yield after quenching is obviously increased, the product quality is greatly improved, the powdering effect is better, the subsequent treatment process is reduced, and the production cost and the safety risk are reduced.
The method is mainly applied to producing insoluble sulfur, and can also be used for processes of rapidly cooling, quenching, milling and the like after gasifying other products, such as milling of some low-boiling-point metals and the like.
