Description

Technical Field

[0001] The invention relates to the technical field of dust removal equipment, and in particular to a desulfurization and deoxidation integrated dust collector device and a dust removal method thereof. Background Art

[0002] A dust collector is a device that separates dust from flue gas. The performance of a dust collector is expressed by the amount of gas that can be processed, the resistance loss when the gas passes through the dust collector, and the dust removal efficiency. At the same time, the price, operation and maintenance costs, service life, and ease of operation and management of the dust collector are also important factors to consider its performance.

[0003] Industrial flue gas contains not only a large amount of solid dust, but also a large amount of sulfur dioxide, carbon dioxide, hydrocarbons and nitrogen oxides. Direct emission will cause serious pollution to the atmospheric environment. Conventional treatment methods mainly separate dust removal and desulfurization and denitrification into steps, which require the use of different equipment in sequence. Due to the low level of integration of this method, the equipment used occupies a large area, and the gas needs to be transferred twice, which seriously affects the flue gas treatment efficiency. Therefore, equipment with dust removal and desulfurization and denitrification capabilities can greatly shorten the flue gas treatment rate and is used to solve the many shortcomings of traditional methods.

[0004] However, the existing equipment has the following shortcomings: With the development of science and technology, the flue gas dust removal method is relatively mature. The main methods of desulfurization and denitrification process include dry and wet methods. The wet treatment method requires a simple structure and the reaction conditions are easier to construct. However, the existing dust removal equipment with desulfurization and denitrification is mainly completed by setting up a group of spray components in the desulfurization and denitrification link. The desulfurization and denitrification are sprayed into the flue gas and the reduction reaction is used to treat the harmful substances. However, the internal cavity area of ​​the equipment is too large, and the flue gas diffusion range is wide. Part of the flue gas will escape the scattered denitrification agent, resulting in unsatisfactory flue gas denitrification.

[0005] Therefore, we propose a desulfurization and deoxidation integrated dust collector device and a dust removal method thereof to solve the above-mentioned problems. Summary of the invention

[0006] The object of the present invention is to provide a desulfurization and deoxidation integrated dust collector device and a dust removal method thereof. Through a liquid curtain construction module connected to a reaction box body, a collecting tank and an external tank body are provided to provide secondary temporary storage space for flue gas and a release agent, with the purpose of increasing the gas pressure and the hydraulic pressure as the cubic volume of the flue gas and the liquid increases. The flue gas is squeezed by each compression nozzle, which can increase the injection rate on the one hand, and determine the direction of flue gas discharge on the other hand to avoid random diffusion of the flue gas. After the release agent is compressed by each fogging nozzle, it is diffused to the periphery of the outer shell in the form of mist. Since a large number of fogging nozzles are provided, and each group of fogging nozzles are equidistantly distributed, and the liquid inlet rate of each external tank body is equal, the liquid mist range formed at each fogging nozzle is basically the same. After a plurality of liquid mists overlap, a complete liquid mist annular surface can be formed on the periphery of the outer shell, ensuring that the smoke beams injected from each compression nozzle can fully cross the interior of the liquid mist annular surface, so as to solve the problems raised by the above-mentioned background technology.

[0013] Preferably, a lower support plate is fixedly mounted on the bottom of the reaction box body, a material gathering funnel is provided at the center of the lower support plate, and a discharge joint is fixedly connected to the bottom of the material gathering funnel.

[0014] Preferably, the outer shell is movably placed inside the reaction box, a group of load-bearing brackets are fixedly installed on the bottom of the outer shell, the outer walls of a group of the load-bearing brackets are connected to the interior of the reaction box, external load-bearing brackets are welded on both sides of the outer wall of the reaction box, and a load-bearing metal base frame is fixedly installed between the bottoms of the two external load-bearing brackets.

[0015] A dust removal method for a desulfurization and deoxidation integrated dust collector device, comprising the following steps: Step 1: Initially complete the connection between the emission device and the equipment to ensure that the tail pipe of the emission device can be connected to the air intake joint. When the equipment is working, the flue gas is continuously transported into the transition box through the tail pipe and the air intake joint. As the flue gas entry time increases, the air pressure in the transition box increases with the increase of the cubic volume of the flue gas.

[0016] Step 2: Due to the characteristics of high-pressure gas flowing to low-pressure areas, the flue gas inside the transition box is transported through the docking pipeline and continuously released into the dust filter box to start dust filtration. The treated flue gas passes through the filter screen vertically and continues to flow to the lower level of the equipment.

[0017] Step 3: The smoke is continuously transported into the collection tank through the first connecting pipe. According to the above principle, as the internal air pressure of the collection tank increases, part of the smoke is evenly dispersed into the diversion joint, and then squeezed by each compression nozzle and diffused outward at high speed.

[0018] Step 4: Before this, turn on each water pump to extract the release agent in the liquid storage tank, and transport it through the primary infusion pipeline and the secondary infusion pipeline into each external tank. Since the T-type pipeline is assembled vertically, the liquid in the liquid storage tank can continuously supplement the missing space in the T-type pipeline under the action of gravity, ensuring that there will be no problem of liquid interruption.

[0019] Step 5: As the liquid in each external tank gradually reaches an overflowing state, part of the liquid will be evenly distributed to each hollow joint, and transported by the second connecting pipe. Finally, it will be compressed by each fog-making nozzle and sprayed out in the form of mist. Multiple liquid mist surfaces overlap to form a closed liquid mist surface on the periphery of the outer shell, which can fully cover the smoke sprayed from the compression nozzle.

[0020] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a secondary temporary storage space for smoke and release agent by setting a liquid curtain building module. The collecting tank and the external tank body provided by the mechanism are used to increase the air pressure and hydraulic pressure as the cubic volume of smoke and liquid increases, so that part of the smoke and liquid can enter the outlet component evenly. The smoke is squeezed by each compression nozzle, which can increase the injection rate on the one hand and determine the direction of smoke discharge on the other hand to avoid random diffusion of smoke. After being compressed by each mist-making nozzle, the release agent is diffused to the periphery of the outer shell in the form of mist. Since a large number of mist-making nozzles are provided and each The group mist nozzles are all equidistantly distributed, and the liquid inlet rate of each external tank is equal, so that the range of liquid mist formed at each mist nozzle is basically the same. After multiple liquid mists overlap, a complete liquid mist annular surface can be formed on the periphery of the outer shell. The mechanism uses the pressure changes generated by each structural container to accurately control the direction of flue gas flow, and constructs a liquid mist annular surface on the periphery of each flue gas discharge, forcing the flue gas flowing in a specified direction to only cross the liquid mist surface at the corresponding position, thereby ensuring that the substances in the flue gas can fully contact with the release agent, thereby improving the effect of flue gas desulfurization and deoxidation.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] Please see attached Figure 1 -Attached Figure 6 As shown, the present invention provides a technical solution: a desulfurization and deoxidation integrated dust collector device, comprising a reaction box 1, and an extended edge 2 is provided inside the reaction box 1.

[0025] according to Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the liquid curtain construction module 7 includes an outer shell 701, a collecting tank 702 is fixedly installed inside the outer shell 701, a sealing top cover 703 is fixedly installed on the top of the collecting tank 702, a group of rectangular frames 705 are fixedly installed on the outer wall of the outer shell 701, a diverter joint 706 is fixedly installed inside each rectangular frame 705, the air inlet end of each diverter joint 706 passes through the outer wall of the collecting tank 702 and is connected to the inside of the collecting tank 702, and a group of hollow sleeves 707 are fixedly installed on the outer wall of each diverter joint 706, each Compression nozzles 708 are fixedly installed inside the hollow sleeve 707, and the air inlet end of each group of compression nozzles 708 is respectively connected to a corresponding diversion joint 706. Support frames 709 are welded at the dead corners of the outer shell sleeve 701, and an external tank body 710 is embedded inside each support frame 709. The outer wall of each external tank body 710 is fixedly connected to a group of second connecting pipes 711, and the discharge end of each second connecting pipe 711 is fixedly connected to a hollow joint 712, and both sides of the outer wall of each hollow joint 712 are fixedly connected to mist-making nozzles 713.

[0026] according to Figure 6 As shown, reinforcing plates 714 are fixedly installed on both sides of the outer wall of the reaction box body 1, and a first metal bracket 715 and a second metal bracket 716 are welded to the outer wall of each reinforcing plate 714. A liquid storage tank 717 is fixedly installed on the top of each first metal bracket 715. By presetting the above components, the release agent required for the reaction is stored, and the liquid storage tank 717 is placed at a specified height to reduce the difficulty of free falling of the liquid.

[0027] according to Figure 2 and Figure 6 As shown, a group of hollow sleeves 718 are fixedly installed inside each second metal bracket 716, a water pump 719 is fixedly inserted into the inner wall of each hollow sleeve 718, and a T-shaped pipe 720 is fixedly connected to the bottom of each liquid storage tank 717. By presetting the above components, since the liquid storage tank 717 and the T-shaped pipe 720 are in a vertical relationship, when the liquid in the T-shaped pipe 720 is quickly consumed, the liquid in the liquid storage tank 717 will quickly flow into the T-shaped pipe 720 to supplement the missing space in the T-shaped pipe 720, thereby avoiding the problem of flow interruption in a certain water pump 719, resulting in inconsistent liquid inflow into the external tank body 710.

[0028] according to Figure 2 and Figure 6As shown, the input end of each group of water pumps 719 is fixedly connected to a primary liquid infusion pipe 721, and the liquid inlet end of each group of primary liquid infusion pipes 721 passes through the outer wall of a corresponding T-shaped pipe 720, and is connected to the interior of the T-shaped pipe 720. By presetting the above components, the output power of each water pump 719 is equal, and the rate of extracting liquid is consistent, thereby ensuring that the liquid mist diffusion surface constructed by each subsequent fog nozzle 713 is consistent.

[0029] according to Figure 4 and Figure 6 As shown, the output end of each water pump 719 is fixedly connected to a secondary liquid infusion pipeline 722 , and the discharge end of each secondary liquid infusion pipeline 722 passes through the top of a corresponding external tank body 710 and is connected to the interior of the external tank body 710 .

[0030] according to Figure 1 , Figure 2 and Figure 6 As shown, an extended edge 2 is fixedly installed on the top of the reaction box body 1, an upper support plate 3 is fixedly installed on the top of the extended edge 2, a dust filter box 4 is fixedly installed on the top of the upper support plate 3, a first connecting pipe 704 is fixedly connected to the top of the sealing top cover 703, and the air inlet ends of the first connecting pipe 704 respectively penetrate the bottom of the upper support plate 3 and the dust filter box 4, and are connected to the interior of the dust filter box 4, a transition box 5 is fixedly installed on the top of the dust filter box 4, a docking pipe is fixedly connected to the bottom of the transition box 5, and the exhaust end of the docking pipe penetrates the top of the dust filter box 4 and is connected to the interior of the dust filter box 4. By presetting the above components, the transition box 5 has a larger space, and the flue gas entering the transition box 5 needs to have a much higher air pressure in the transition box 5 than the dust filter box 4 to meet the discharge conditions, so that the flue gas discharge method is indirect, which can reduce the processing load of the filter components in the dust filter box 4 and improve the subsequent flue gas filtration effect.

[0031] according to Figure 2 and Figure 3 As shown, a lower support plate 8 is fixedly installed at the bottom of the reaction box 1, and a gathering funnel 9 is provided at the center of the lower support plate 8. A discharge joint 10 is fixedly connected to the bottom of the gathering funnel 9. By presetting the above components and utilizing the structural characteristics of the gathering funnel 9, the treated liquid will enter the gathering funnel 9 under the action of gravity, gather toward the middle, and finally be discharged from the discharge joint 10.

[0032] according to Figure 1 , Figure 2 and Figure 5As shown, the outer shell 701 is movably placed inside the reaction box 1, and a group of load-bearing brackets 723 are fixedly installed at the bottom of the outer shell 701. The outer walls of the group of load-bearing brackets 723 are connected to the interior of the reaction box 1, and external load-bearing brackets 11 are welded on both sides of the outer wall of the reaction box 1. A load-bearing metal base frame 12 is fixedly installed between the bottoms of the two external load-bearing brackets 11.

[0033] The effect achieved by the entire mechanism is as follows: first, the equipment is moved to the designated working area, and the bottom of the stressed metal chassis 12 is fully in contact with the ground, the discharge device and the equipment are manually docked, the tail pipe of the former is fully connected to the air intake connector 6, and then the external line is connected to the power supply of the equipment, in order to provide energy for multiple electrical components therein, each water pump 719 is turned on, so that a relatively strong adsorption force is formed at the liquid inlet end of a corresponding primary infusion pipe 721, and the release agent in the liquid storage tank 717 is continuously extracted, and the liquid enters each external tank body 710 in turn through the primary infusion pipe 721 and the secondary infusion pipe 722. Since the output power of each water pump 719 is equal, the amount of liquid inflow in each external tank body 710 is basically the same. As the liquid in each external tank body 710 reaches the overflowing state step by step, part of the liquid will be evenly squeezed into each second connecting pipe 711 and merged into a corresponding hollow joint 712. The liquid is then compressed by each mist nozzle 713 and sprayed toward the periphery of the outer shell 701. When each liquid mist surface is in equal contact and overlapped, a complete liquid mist annular surface will be formed on the periphery of the outer shell 701. The flue gas generated in the discharge device is continuously transported into the transition box 5 through the tail pipe and the air inlet joint 6. As the cubic volume of the flue gas in the transition box 5 increases, the internal pressure gradually increases, so that a high-low pressure environment is formed between the transition box 5 and the dust filter box 4. Part of the high-pressure flue gas will continue to enter the dust filter box 4 through the transportation of the docking pipe and longitudinally pass through the dust filter. In the filter assembly in box 4, the flue gas filtration is completed, and the treated flue gas is then transported into the collection tank 702 through the first connecting pipe 704. Through the above principle, as the air pressure in the collection tank 702 increases, part of the flue gas is evenly squeezed into each diversion joint 706, and the subsequent flue gas is squeezed by each compression nozzle 708 and sprayed toward the periphery of the outer shell 701 at a high speed. Since the initial speed of each beam of smoke is relatively fast, it can be ensured that each beam of smoke can fully cross the annular liquid mist surface to avoid the diffusion of smoke in the middle.

[0034] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
