Description

Technical Field

[0001] This utility model relates to the field of biological desulfurization equipment technology, specifically an integrated biological desulfurization reactor. Background Technology

[0002] Biological desulfurization involves the selective oxidation of sulfur-containing compounds by microorganisms or enzymes, breaking the CS bonds and oxidizing sulfur atoms into sulfates or sulfites, which are then transferred to the aqueous phase. Meanwhile, the DBT skeleton is oxidized to hydroxybiphenyl, remaining in the oil phase, thus achieving the removal of sulfides. This technology utilizes aerobic or anaerobic bacteria to decompose sulfides at ambient temperature and pressure, preserving the organic carbon skeleton. It is widely used in the treatment of petroleum, natural gas, and industrial waste gases, and features low energy consumption and the recoverability of sulfur resources.

[0003] Currently, most desulfurization scrubbing towers use uniform, fine packing material. While this improves desulfurization efficiency, it is also more expensive. Furthermore, the denser distribution of fine packing material leads to a heavier load on the packing bed over long periods. If the packing material in the middle reacts violently, it is prone to blockage due to temperature rise or scaling, ultimately affecting desulfurization efficiency and increasing the frequency of equipment maintenance.

[0004] If coarse packing is used, although it can meet the daily production needs, the desulfurization efficiency and effect are generally poor. At the same time, due to the large gaps between coarse packing, the gas flow rate is faster in the middle of the packing, resulting in a lower gas flow rate at the edge of the packing, which reduces the utilization rate of the packing and affects the desulfurization efficiency.

[0005] Therefore, we propose to design an integrated biological desulfurization reactor. Utility Model Content

[0006] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract, and the title, and such simplifications or omissions should not be used to limit the scope of this utility model.

[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0008] An integrated biological desulfurization reactor includes a desulfurization tower body. Sulfur-containing gas pipes and liquid discharge pipes are fixedly connected to both sides of the outer wall of the desulfurization tower body near the bottom, respectively. The sulfur-containing gas pipes penetrate the desulfurization tower body and are fixedly connected to a special-shaped pipe. A central nozzle is provided at the center of the top of the special-shaped pipe, and an edge nozzle is fixedly connected to the outside of the special-shaped pipe.

[0009] An exhaust pipe is provided at the center of the top of the desulfurization tower body, and an inlet pipe is fixedly connected to the outer wall of the desulfurization tower body near the top. The inlet pipe passes through the side wall of the desulfurization tower body and is fixedly connected to a spray head.

[0010] The desulfurization tower body is equipped with a packing assembly near the middle. The packing assembly includes an outer packing cylinder and an inner packing cylinder at the center of the outer packing cylinder. A partition is fixedly connected between the outer and inner packing cylinders. Fine packing is placed between two adjacent partitions. Coarse packing is placed inside the inner packing cylinder. An external feed inlet is fixedly connected to the bottom of the outer packing cylinder. An internal feed inlet is placed at the center of the external feed inlet. Both the external and internal feed inlets are equipped with mesh plates.

[0011] As a preferred embodiment of the integrated biological desulfurization reactor described in this utility model, five central nozzles are provided, which are evenly distributed in the middle of the shaped tube, and eight edge nozzles are provided, which are evenly distributed at the outer edge of the shaped tube, so as to facilitate the uniform supply of sulfur-containing gas into the desulfurization tower.

[0012] As a preferred embodiment of the integrated biological desulfurization reactor described in this utility model, the cross-section of the irregularly shaped tube is arranged in a star shape. Through the star-shaped gas chamber design, the sulfur-containing gas in the sulfur-containing gas pipe can be better supplied to the edge nozzles at the end.

[0013] As a preferred embodiment of the integrated biological desulfurization reactor described in this utility model, the central nozzle corresponds to the position of the inner feed inlet and the inner packing cylinder, and the edge nozzle corresponds to the position of the outer feed inlet and the outer packing cylinder. The central nozzle can supply gas to the inner packing cylinder for dispersion, while the edge nozzle can directly supply gas to the outer packing cylinder for dispersion, which facilitates better reaction with the biological solution sprayed from the top for desulfurization.

[0014] As a preferred embodiment of the integrated biological desulfurization reactor described in this utility model, the area of ​​the outer feed inlet is three times the area of ​​the inner feed inlet. The outer feed inlet corresponds to fine packing, and the inner feed inlet corresponds to coarse packing. This achieves the following effects: most of the sulfur-containing gas enters the fine packing on the outside for reaction, while a small portion of the sulfur-containing gas enters the coarse packing on the inside for reaction, keeping the reaction rates of the two packings equal. This improves the overall reaction uniformity, avoids local overload, optimizes the packing performance, and enhances desulfurization efficiency.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention utilizes the cooperation between sulfur-containing gas pipes, shaped pipes, and packing components to distribute inner and outer double packing channels within the desulfurization tower. This facilitates improved reaction uniformity within the desulfurization tower, avoids localized overload, and optimizes the packing distribution structure, achieving a balance between high efficiency and economy.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-4 This utility model provides an integrated biological desulfurization reactor, including a desulfurization tower body 1. Sulfur-containing gas pipe 2 and a drain pipe 3 are fixedly connected to the two sides of the outer wall of the desulfurization tower body 1 near the bottom, respectively. The sulfur-containing gas pipe 2 passes through the desulfurization tower body 1 and is fixedly connected to a special-shaped pipe 4. A central nozzle 401 is provided at the center of the top of the special-shaped pipe 4, and an edge nozzle 402 is fixedly connected to the outside of the special-shaped pipe 4.

[0027] In this embodiment, the cross-section of the irregular tube 4 is arranged in a star shape. Through the star-shaped air chamber design, the sulfur-containing gas in the sulfur-containing gas pipe 2 can be better supplied to each edge nozzle 402 at the end.

[0028] Five central nozzles 401 are provided, which are evenly distributed in the middle of the shaped tube 4. Eight edge nozzles 402 are provided, which are evenly distributed at the outer edge of the shaped tube 4, so as to facilitate the uniform supply of sulfur-containing gas into the desulfurization tower body 1.

[0029] An exhaust pipe 5 is installed at the center of the top of the desulfurization tower body 1. An inlet pipe 6 is fixedly connected to the outer wall of the desulfurization tower body 1 near the top. The inlet pipe 6 passes through the side wall of the desulfurization tower body 1 and is fixedly connected to a spray head 7.

[0030] A packing assembly 8 is installed near the middle of the desulfurization tower body 1. The packing assembly 8 includes an outer packing cylinder 801, an inner packing cylinder 802 is installed at the center of the outer packing cylinder 801, a partition 803 is fixedly connected between the outer packing cylinder 801 and the inner packing cylinder 802, fine packing 804 is installed between two adjacent partitions 803, coarse packing 805 is installed inside the inner packing cylinder 802, an outer feed inlet 9 is fixedly connected to the bottom of the outer packing cylinder 801, an inner feed inlet 10 is installed at the center of the outer feed inlet 9, and a mesh plate 11 is installed inside both the outer feed inlet 9 and the inner feed inlet 10.

[0031] The central nozzle 401 corresponds to the inner feed inlet 10 and the inner packing cylinder 802, while the edge nozzle 402 corresponds to the outer feed inlet 9 and the outer packing cylinder 801. The central nozzle 401 can supply gas to the inner packing cylinder 802 for dispersion, while the edge nozzle 402 can directly supply gas to the outer packing cylinder 801 for dispersion, which facilitates better reaction with the biological solution sprayed from the top for desulfurization.

[0032] In this embodiment, the area of ​​the outer feed inlet 9 is three times the area of ​​the inner feed inlet 10. The outer feed inlet 9 corresponds to the fine packing 804, and the inner feed inlet 10 corresponds to the coarse packing 805. This has the following effect: most of the sulfur-containing gas enters the outer fine packing 804 for reaction, and a small part of the sulfur-containing gas enters the inner coarse packing 805 for reaction, so that the reaction rates of the two are kept equal, thereby improving the overall reaction uniformity, avoiding local overload, optimizing the packing performance, and improving the desulfurization efficiency.

[0033] In use, sulfur-containing gas is introduced into the desulfurization tower body 1 through sulfur-containing gas pipe 2, and biological solution is sprayed through inlet pipe 6 and sprayed by spray head 7. The spraying range includes the outer packing cylinder 801 and the inner packing cylinder 802.

[0034] There are six edge nozzles 402 evenly distributed in a ring, corresponding to the outer packing cylinder 801, while there are five center nozzles 401, corresponding to the position of the inner packing cylinder 802, so that most of the sulfur-containing gas can enter through the outer feed port 9, and a small part of the sulfur-containing gas can enter the packing assembly 8 through the inner feed port 10.

[0035] During the production of the outer packing cylinder 801, inner packing cylinder 802, outer feed inlet 9, and inner feed inlet 10, the relevant dimensions were finally determined through multiple sets of experiments to keep the internal and external reaction rates as equal as possible, thereby improving the uniformity of the reaction inside the desulfurization tower 1 and avoiding local overload.

[0036] Meanwhile, the fine packing 804 has a large surface area, which can handle most of the sulfur-containing gas. Through sufficient contact, it ensures that most of the sulfur-containing gas is efficiently removed. The coarse packing 805 has a small surface area, but handles a small amount of sulfur-containing gas. It has large pores and low resistance, which makes it easier to share the processing pressure of the fine packing 804.

[0037] When most of the sulfur-containing gas is introduced into the fine packing 804, a small portion of the gas flows through the coarse packing 805, which can reduce the load on the fine packing 804. At the same time, the coarse packing 805 can serve as an "auxiliary channel" to balance the pressure and extend the equipment maintenance cycle.

[0038] Fine packing 804 is generally more expensive and is only used on the outer side to treat most of the gas, so that it can concentrate its high-efficiency desulfurization function; coarse packing 805 is less expensive and is used on the inner side to treat a small portion of the gas, which can meet the reaction requirements and reduce the overall packing cost, achieving a balance between high efficiency and economy.

[0039] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
