The invention relates to chemical environment-friendly equipment, in particular to a combustor for a sulfur-containing waste liquid regeneration acid making device. On the basis, the invention also relates to a device and a method for regenerating and preparing acid by using the sulfur-containing waste liquid.
Background
With the progress of industrial production technology, while the production efficiency is increasing, mankind is also facing serious challenges in the aspect of atmospheric environmental protection. One of the main major causes of atmospheric pollution is oxynitride, and the treatment of nitrogen oxides is not slow. For various sulfur-containing waste liquid generated in industrial production, sulfur resources in the waste liquid can be recycled through a regeneration acid preparation mode, however, for example, in an industrial device for preparing acid through cracking and regeneration of alkylated waste acid and burning the acrylonitrile sulfur-containing waste liquid, the problem that NO x in discharged tail gas cannot reach the standard often exists.
The related research data show that NO x generated by combustion is mainly divided into thermal NO x, rapid NO x and fuel NO x, and the influencing factors mainly comprise nitrogen element in fuel, local high temperature, flue gas residence time, oxygen-enriched combustion and the like. Therefore, in the regeneration acid production technology, the generation of NO x in the combustion process can be reduced by controlling the fuel type, the combustion temperature, the combustion time and the like.
At present, two main measures are taken in the industry: one is to add denitration facilities to a cracking or converting unit of the acid making device, but the technology is still immature, and after NH 3 is sprayed, the stable operation of the acid making device is adversely affected; another is to use a low nitrogen burner with internal flue gas recirculation to reduce the formation of NO x by reducing the oxygen concentration in the flame zone, which is also not satisfactory.

Detailed Description
The following describes specific embodiments of the present invention in detail with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the invention, are not intended to limit the invention.
In the present invention, unless otherwise specified, terms such as "upper, lower, left, and right" and "upper, lower, left, and right" are used generically to refer to the upper, lower, left, and right illustrated in the drawings; "inner and outer" means inner and outer relative to the contour of the respective parts themselves.
Referring to fig. 1, a burner for a sour plant for regenerating sulfur-containing waste liquid according to a preferred embodiment of the present invention includes a burner cylinder 1 and a center tube assembly 2 extending through a center line of the burner cylinder 1. Wherein the burner cylinder 1 may be formed in a substantially cylindrical shape and have opposite first and second ends. The burner cylinder 1 is provided with a combustion air inlet 11 for the introduction of a combustion air, such as pressurized air, through which combustion air inlet 11 the combustion air introduced can be conveyed to the second end via the inner chamber of the burner cylinder 1, i.e. the combustion air channel 16 formed by the radial space between the burner cylinder 1 and the central tube assembly 2, for combustion reaction with the fuel air introduced by the fuel air channel of the central tube assembly 2 as described later. The burner cylinder 1 is furthermore provided with an ignition device 12 arranged at its second end. In a preferred embodiment, the ignition device 12 may be mounted on the operating panel 13 at the first end of the burner cylinder 1 and extend to the position of the second end in order to perform ignition maneuvers. Further, the ignition device 12 may include an igniter 12a and a pilot burner 12b provided near the free end of the second end of the center tube assembly 2 for the ignition and stable operation of the combustion process of the fuel gas burner 231 described later, respectively.
In the burner, the center tube assembly 2 extends at least from a first end to a second end of the burner cylinder 1 so that fuel gas or the like is introduced into the center tube assembly 2 at the first end and burned at the second end. Specifically, the center tube assembly 2 includes an inner tube 21, an intermediate tube 22, and an outer tube 23 coaxially disposed with each other from the inside to the outside, whereby three sets of passages are defined in the center tube assembly 2: the free end of the inner tube 21, which is positioned at the second end, is provided with a waste liquid nozzle 211, so that the burner can be utilized and the sulfur-containing waste liquid can be directly introduced into the hearth of the combustion furnace through the sulfur-containing waste liquid channel thereof without separately arranging an installation space for a waste liquid spray gun; the atomizing air channel can spray pressure air flow (such as pressurized air with relatively high pressure) to the waste liquid nozzle 211, so that the sulfur-containing waste liquid sprayed by the waste liquid nozzle 211 is atomized and sprayed into the hearth; the fuel gas channel can be used to deliver fuel gas, such as natural gas, methane, etc., which can be combusted at the point where the waste liquid nozzle 211 ejects the sulfur-containing waste liquid to produce a combustion flame.
Thus, the burner of the present invention is integrated with the waste liquid spray gun, so that it is unnecessary to provide a separate installation space for the waste liquid spray gun on the burner of the sulfur-containing waste liquid regeneration acid making apparatus. More importantly, by locating the combustion flame generated by the combustion of the fuel gas at the location of the ejection of the sulfur-containing effluent, the combustion heat can be absorbed by the sulfur-containing effluent decomposition process, thereby avoiding excessive local temperature at the flame center. At the same time, the spraying action of the atomized wind and the sulfur-containing waste liquid forms a low pressure area near the waste liquid nozzle 211, which can entrain part of the flue gas generated by combustion in the hearth to mix towards the combustion position, thereby reducing the oxygen content of the combustion area and effectively inhibiting the generation of NO x in the regeneration acid making process.
On the basis, the invention also provides a sulfur-containing waste liquid regeneration acid making device which is different from the prior art that a burner and a waste liquid spray gun are independently arranged on a combustion furnace, and the sulfur-containing waste liquid regeneration acid making device is provided with the burner, so that the sulfur-containing waste liquid can be directly sprayed into a hearth of the combustion furnace by using the burner, the spraying position of the sulfur-containing waste liquid is positioned in the combustion flame center of fuel gas, and the heat generated by combustion can be absorbed by using the decomposition process of the sulfur-containing waste liquid, so that the generation of NO x caused by the overhigh local temperature of the flame center can be avoided. At the same time, the spraying action of the atomized wind and the sulfur-containing waste liquid forms a low pressure area near the waste liquid nozzle, which draws a part of flue gas in the hearth to the combustion position, thereby further inhibiting the generation of NO x in the regeneration acid making process by reducing the oxygen content of the combustion area.
The device for regenerating and preparing the acid by using the sulfur-containing waste liquid can be used in regeneration and acid preparation processes based on various sulfur-containing waste liquids, and therefore, the invention also provides a method for regenerating and preparing the acid by using the sulfur-containing waste liquid of the device for regenerating and preparing the acid by using the sulfur-containing waste liquid, wherein the sulfur-containing waste liquid which is introduced into a sulfur-containing waste liquid channel of a combustor and used for regenerating and preparing the acid can contain at least one of sulfuric acid, sulfurous acid, ammonium sulfate, ammonium bisulfate, sodium sulfate, potassium sulfate and ammonium sulfite. In order to promote the atomization of the sulfur-containing waste liquid by utilizing the air flow introduced into the atomization air channel, the pressure of the atomization air should be set relatively high, for example, the pressure of the atomization air output by the atomization air channel can be not less than 0.3MPa.
With continued reference to fig. 1, the space between the center tube assembly 2 and the burner cylinder 1 is formed as a combustion air channel 16 for the flow of combustion-supporting gas, which combustion air channel 16 may be provided with a swirl plate 3 at a position near the second end, which swirl plate 3 is arranged to be able to direct the flow of combustion-supporting air introduced by the combustion-supporting air inlet 11 in a spiral manner in the direction of the second end. With this arrangement, the combustion air passage 16 forms a swirl flow of the combustion air discharged into the furnace through the second end of the burner cylinder 1, which can sufficiently burn the fuel gas and ensure the stability of the combustion flame generated by the combustion.
In a preferred embodiment, a flame stabilizing cap 4 arranged around the central tube assembly 2 may also be attached to the second end of the burner cylinder 1, which also helps to maintain the stability of the combustion flame.
In the above-described burner, the center tube assembly 2 may be mainly formed by nesting three concentric circular tubes to form a sulfur-containing waste liquid passage, an atomizing wind passage, and a fuel gas passage in different radial spaces. In order to absorb the heat generated by the combustion of the fuel gas by the decomposition process of the sulfur-containing waste liquid, the combustion flame generated by the combustion of the fuel gas needs to cover the sulfur-containing waste liquid ejected from the waste liquid nozzle 211 as much as possible. For this purpose, sulfur-containing waste liquid may be caused to be ejected from an annular region surrounding the waste liquid nozzle 211. Generally, in order to facilitate the ejection of sulfur-containing waste liquid, the waste liquid nozzle 211 has a relatively large radial dimension compared to the main body portion of the inner tube 21 so as to atomize the waste liquid nozzle 211 ejected therefrom by mechanical means or compressed gas means. In this regard, one end of the fuel gas channel near the waste liquid nozzle 211 may be provided with a plurality of fuel gas burners 231 arranged around the waste liquid nozzle 211, such as four, six or eight fuel gas burners 231 uniformly arranged in the circumferential direction around the waste liquid nozzle 211.
In order to isolate the high temperatures generated by combustion and to facilitate the operation of the operator, the first end of the burner cylinder 1 may be provided with an operating panel 13. As described above, the igniter 12a, the pilot lamp 12b, and the like may be fixed to the operation panel 13 and extended to the position of the second end. Furthermore, the center tube assembly 2 may be arranged to extend through the operation panel 13 at the first end, and is provided with a sulfur-containing waste liquid inlet 212 at a portion of the inner tube 21 extending out of the burner cylinder 1, an atomizing wind inlet 221 at a portion of the intermediate tube 22 extending out of the burner cylinder 1, and a fuel gas inlet 232 at a portion of the outer tube 23 extending out of the burner cylinder 1, respectively. In this case, the combustion air inlet 11 may be provided on the side wall of the burner cylinder 1, thereby facilitating the rational arrangement of the parts.
Further, the operation panel 13 is mounted with a flame detector 14 and/or a flame viewing hole 15 so as to directly monitor the combustion condition at the fuel gas burner 231 by a sensor or a person. Wherein the number of flame detectors 14 is not less than two, such as three.
In the above-mentioned burner, the waste liquid nozzle 211 may be made of silicon carbide, alloy 20 (Alloy 20) or 904L; the fuel gas burner 231 may be made of stainless steel such as 310S, 304 or 316; the material of the burner cylinder 1 is preferably carbon steel or stainless steel, preferably 304 stainless steel. The inner tube 21 of the central tube assembly 2 may be made of corrosion-resistant alloy steel, and the intermediate tube 22 and the outer tube 23 may be made of alloy steel.
The burner and the sulfur-containing waste liquid regeneration acid making device are in a special structural form, and the waste liquid nozzle is arranged at the center of the fuel gas burner, so that the waste liquid is atomized and then is sprayed into the hearth at a high speed, the generation of NO x is greatly reduced, and the burner and the sulfur-containing waste liquid regeneration acid making device are suitable for various waste sulfuric acid and sulfur-containing waste liquid high-temperature incineration acid making devices produced in industries such as chemical industry, petrochemical industry and the like.

Within the scope of the technical idea of the invention, a number of simple variants of the technical solution of the invention are possible, including combinations of individual specific technical features in any suitable way.
