Abstract
Description
Technical Field
[0001] This utility model relates to the field of desulfurization reaction technology, specifically to a high-efficiency cyclone reactor device for dry desulfurization. Background Technology
[0002] In recent years, dry desulfurization technology has been widely used in desulfurization systems for boilers and industrial kilns. The desulfurizing agent is ground into ultrafine powder (ultrafine powder of sodium-based or calcium-based desulfurizing agent), and then sprayed into the reactor through a dry desulfurization spray gun. The ultrafine powder mixes with the flue gas in the reactor and reacts to remove SO2 from the flue gas.
[0003] The existing reactor system has a low degree of mixing between the desulfurizing agent and the flue gas, and the distribution of the desulfurizing agent in the flue gas cross section is very uneven. This results in uneven mixing of the dry powder desulfurizing agent with the flue gas, leading to low reaction efficiency of dry desulfurization. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this invention provides a high-efficiency cyclone reactor device for dry desulfurization, thereby solving the problems mentioned in the background section.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency cyclone reactor device for dry desulfurization, wherein a cyclone reactor inlet is provided on the side of the return bucket elevator, a cyclone reactor is fixedly installed on the right side of the cyclone reactor inlet, a cyclone reactor outlet flue is fixedly installed on the top surface of the cyclone reactor, an ash hopper is fixedly installed on the bottom surface of the cyclone reactor, a discharge airlock is fixedly installed on the bottom surface of the ash hopper, a return three-way valve is provided on the bottom surface of the discharge airlock, a return screw one is provided on one side of the return three-way valve, a return screw two is provided below the return screw one, and a level gauge is fixedly installed on the side of the ash hopper.
[0008] Preferably, spiral blades are movably installed on the inner sides of the first and second return spirals.
[0009] Preferably, the outlet flue of the cyclone reactor is connected to the interior of the cyclone reactor.
[0010] Preferably, the ash hopper is internally connected to the return material three-way valve.
[0011] Preferably, the first return screw and the second return screw are connected by a channel.
[0012] Preferably, the return material three-way valve is provided with a collection container on the side away from the return material screw one and the return material screw two.
[0013] Compared with the prior art, this utility model provides a high-efficiency cyclone reactor device for dry desulfurization, which has the following beneficial effects:
[0014] 1. The high-efficiency cyclone reactor device for dry desulfurization firstly involves the flue gas to be treated in the cyclone reactor contacting and reacting with the desulfurizing agent injected into the flue. The gas enters the reactor tangentially, i.e., via a return bucket elevator, and rotates downwards along the reactor wall. After reaching the bottom of the ash hopper, the gas rotates upwards along the axis. During the entire gas flow, the dry powder desulfurizing agent and the flue gas to be treated undergo intense rotation and mixing inside the cyclone reactor, while the desulfurizing agent reacts with the acid-washing pollutants in the flue gas.
[0015] 2. This high-efficiency cyclone reactor device for dry desulfurization collects flue gas particles and unreacted desulfurizing agent from the flue gas after desulfurization due to the dust removal effect of the cyclone. The collected dust is temporarily stored in the ash hopper. Most of the desulfurization ash enters the return three-way valve through the discharge lock, and then enters the return bucket elevator through return screw one and return screw two. When the level gauge alarms, the return three-way valve is switched to the ash discharge position for timed ash discharge to maintain system balance. The return bucket elevator then lifts the desulfurization ash back to the inlet of the cyclone reactor, where it re-enters the cyclone reactor for multiple reactions. The flue gas after the reaction is discharged through the outlet flue of the cyclone reactor and enters the next stage dust collector system. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] like Figure 1As shown, this utility model provides a technical solution: a high-efficiency cyclone reactor device for dry desulfurization, wherein a cyclone reactor inlet 8 is provided on the side of a return bucket elevator 1, a cyclone reactor 3 is fixedly installed on the right side of the cyclone reactor inlet 8, a cyclone reactor outlet flue 2 is fixedly installed on the top surface of the cyclone reactor 3, an ash hopper 10 is fixedly installed on the bottom surface of the cyclone reactor 3, a discharge airlock 4 is fixedly installed on the bottom surface of the ash hopper 10, a return three-way valve 5 is provided on the bottom surface of the discharge airlock 4, a return spiral 6 is provided on one side of the return three-way valve 5, a return spiral 7 is provided on the lower side of the return spiral 6, and a level gauge 9 is fixedly installed on the side of the ash hopper 10.
[0020] Furthermore, spiral blades are movably installed on the inner sides of return spiral 6 and return spiral 7.
[0021] Through the above technical solution, during the return process of the reacted dust in the cyclone reactor 3 through return screw 6 and return screw 7, the spiral blades set on the inner side can help the dust move, avoiding dust accumulation that could cause return screw 6 and return screw 7 to be blocked.
[0022] Furthermore, the outlet flue 2 of the cyclone reactor is connected to the interior of the cyclone reactor 3.
[0023] Through the above technical solution, the flue gas that has been reacted in the cyclone reactor 3 can be discharged through the cyclone reactor outlet flue 2 and enter the next stage dust removal system.
[0024] Furthermore, the ash hopper 10 is internally connected to the return material three-way valve 5.
[0025] Through the above technical solution, the dust in the ash hopper 10 can be discharged through the return three-way valve 5. After the return three-way valve 5 is closed, the dust can be temporarily stored in the ash hopper 10.
[0026] Furthermore, return screw 6 and return screw 7 are connected by a channel.
[0027] Through the above technical solution, dust in return screw 6 and return screw 7 can move through the closed channel to prevent leakage.
[0028] Furthermore, the return material three-way valve 5 is provided with a collection container on the side away from the return material screw 6 and the return material screw 7.
[0029] With the above technical solution, the emitted dust can be collected and treated in a centralized manner.
[0030] Working principle: The flue gas to be treated in the cyclone reactor 3 first comes into contact with and reacts with the desulfurizing agent injected into the flue. It enters the reactor tangentially from the cyclone reactor 3, i.e., the return bucket elevator 1, and rotates from top to bottom along the wall of the cyclone reactor 3. After reaching the bottom of the ash hopper 10, the airflow turns and rotates upward along the axis. During the entire airflow movement, the dry powder desulfurizing agent and the flue gas to be treated undergo intense rotation and mixing inside the cyclone reactor 3. At the same time, the desulfurizing agent reacts with the acid washing pollutants in the flue gas. The flue gas particles after desulfurization and the unreacted desulfurizing agent are collected by the cyclone reactor 3 due to the dust removal effect of the cyclone. The collected dust is temporarily stored in ash hopper 10. Most of the desulfurization ash enters the return three-way valve 5 through the discharge airlock 4, and then enters the return bucket elevator 1 through return screw 1 6 and return screw 2 7. When the level gauge 9 alarms, the return three-way valve 5 is switched to the ash discharge position for timed ash discharge to maintain system balance. The return bucket elevator 1 then lifts the desulfurization ash back to the inlet 8 of the cyclone reactor, where it re-enters the cyclone reactor 3 for multiple reactions. The flue gas after the reaction is discharged through the outlet flue 2 of the cyclone reactor and enters the next stage dust collector system.
