Description

TECHNICAL FIELD

[0001] The utility model relates to fenton fluidized bed equipment technical field, concretely is a kind of integrated circulating fenton fluidized bed's medicament control device. BACKGROUND

[0002] Fenton fluidized bed is a kind of wastewater treatment technology, it generates strong oxidizing hydroxyl radical by using Fenton reagent (hydrogen peroxide and ferrous ion) in fluidized bed reactor, to efficiently degrade refractory organic matter in wastewater. This method can effectively reduce chemical sludge production, improve treatment efficiency, and is suitable for the treatment of various industrial wastewater.

[0003] Fenton fluidized bed technology plays an important role in wastewater treatment, which relies on precise chemical proportioning to achieve the best results. In this process, specific reagents such as hydrogen peroxide solution and ferrous sulfate solution need to be added to the wastewater. The mixing ratio of these reagents with sewage is crucial, as it directly affects the treatment efficiency and the final water quality. However, due to the experience of the operator and the accuracy of the time control, manual reagent feeding often has certain errors, which not only may reduce the effect of wastewater treatment, but also may cause waste of reagents and unnecessary consumption of human resources. In order to improve the consistency and efficiency of treatment, automatic control of the amount of reagent feeding can significantly reduce human errors, ensure the stability and economy of the wastewater treatment process.

[0004] In view of the above problems, it is urgent to make innovative design on the basis of the original reagent control device. INVENTION CONTENTS

[0008] Preferably, the guide plates are distributed in a zigzag pattern within the box.

[0009] Preferably, the dosing structure includes a box body, a partition, a feed pipe, a guide block, an open toothed plate, a gear roller, a piston rod, a cylinder fixing plate, and a pressure spring. The box body is connected to the partition, and the bottom of the box body is connected to each side of the partition with a feed pipe. The lower end of the feed pipe is connected to the wastewater inlet pipe. Each feed pipe is connected to a guide block, and an open toothed plate is attached to the bottom of the guide block.

[0012] Compared with existing technologies, the beneficial effects of this invention are as follows: The integrated circulating Fenton fluidized bed reagent control device, through the coordinated operation of the wastewater inlet pipe and the dosing structure, allows wastewater to be transported into the tank for treatment via the inlet pipe. Simultaneously, this flow process activates the dosing structure, precisely dispensing the reagent solution into the wastewater flow. This design offers two major advantages: First, the dosing structure releases the appropriate amount of reagent only when the wastewater is flowing, ensuring an optimal mixing ratio between wastewater and reagent and avoiding ineffective reagent dosing. Second, the system can intelligently adjust the reagent dosage based on the wastewater flow rate in the pipeline, preventing reagent waste and ensuring the accuracy of reagent-wastewater mixing.

[0013] Furthermore, through a carefully designed filtration structure, wastewater is restricted during its flow, forced to meander along the baffles. This tortuous path design allows for more sufficient contact and reaction time between the wastewater and the catalyst core layer. This setup not only improves wastewater treatment efficiency but also enhances the catalyst's effect, ensuring maximum wastewater treatment effectiveness. Through this precise process control, we can achieve highly efficient wastewater treatment while optimizing resource utilization, achieving both environmental and economic benefits.

The top of the tank 1 is equipped with a stirring shaft 2, and a filter structure 3 is provided between the tank 1 and the outer wall of the stirring shaft 2. The top two sides of the tank 1 are respectively equipped with a water outlet pipe 4 and a circulation pipe 5. The end of the circulation pipe 5 is connected to the wastewater inlet pipe 6 and the tank 1. One end of the wastewater inlet pipe 6 is connected to the bottom of the tank 1, and the other end of the wastewater inlet pipe 6 is connected to a water pump 7. A dosing structure 8 is connected to the wastewater inlet pipe 6.

[0021] The filter structure 3 includes a box 301, guide plates 302, openings 303, and catalyst core layer 304. The box 301 is provided inside the tank 1, and several guide plates 302 are provided inside the box 301. Openings 303 are provided on the upper and lower sides of the box 301 corresponding to the guide plates 302, and catalyst core layer 304 is installed between the guide plates 302.

[0022] The guide plates 302 are distributed in a zigzag pattern inside the box 301.

[0023] The dosing structure 8 includes a housing 801, a partition 802, a feed pipe 803, a guide block 804, an open toothed plate 805, a gear roller 806, a piston rod 807, a cylinder 808, a fixing plate 809, and a pressure spring 810. The housing 801 is connected to the partition 802, and a feed pipe 803 is connected to each side of the bottom of the housing 801 about the partition 802. The lower end of each feed pipe 803 is connected to the wastewater inlet pipe 6. Each feed pipe 803 is connected to a guide block 804, and an open toothed plate 805 is attached to the bottom of the guide block 804. 5. The open toothed plate 805 is slidably connected to the feed pipe 803. One side of the feed pipe 803 is meshed with a gear roller 806, and the other side of the outer wall of the gear roller 806 is meshed with a piston rod 807. The lower end of the piston rod 807 is located inside the wastewater inlet pipe 6. The piston rod 807 is sleeved with a cylinder 808, and the cylinder 808 is connected to the wastewater inlet pipe 6. The piston rod 807 is connected to a fixing plate 809 in the inner and outer wall areas of the cylinder 808, and a pressure spring 810 is connected between the fixing plate 809 and the cylinder 808.

[0024] The open toothed plate 805 has an opening that penetrates both ends of the feed pipe 803 in the area inside the feed pipe 803, and a sealing element is provided in the area where the open toothed plate 805 connects with the feed pipe 803.

[0025] The lower end of the piston rod 807 is inclined near the water pump 7, and the piston rod 807 and the cylinder 808 are slidably connected.

[0026] Working principle: According to Figure 1 As shown, hydrogen peroxide solution and ferrous sulfate solution are first injected into the box 301, and separated by guide plate 302. Water pump 7 delivers wastewater to tank 1 through wastewater inlet pipe 6. During this process, depending on the flow rate of wastewater in wastewater inlet pipe 6, the piston rod 807 contacts the inclined surface at the lower end, and the force is greater than that of pressure spring 810, pushing piston rod 807 to move upward. This process will drive the meshing gear roller 806 to rotate. The gear roller 806 simultaneously drives the opening tooth plate 805 to translate, so that the opening on the opening tooth plate 805 is misaligned or aligned with the guide block 804 in the feed pipe 803, changing the amount of reagent in the box 801 falling from feed pipe 803 to wastewater inlet pipe 6.

[0027] The larger the wastewater volume in the wastewater inlet pipe 6, the longer the piston rod 807 moves upward, and the more aligned the opening on the opening tooth plate 805 is with the guide block 804 inside the feed pipe 803. The smaller the wastewater volume in the wastewater inlet pipe 6, the more aligned the opening and guide block 804 are with the open pipe 805.

[0028] Wastewater and reagents are stirred in tank 1 by stirring shaft 2, and then enter through port 303 at the bottom of box 301. After reacting in catalyst core layer 304, they flow out from port 303 at the top of tank 1, and then pass through outlet pipe 4 and circulation pipe 5. This is the working principle of the reagent control device of integrated circulating Fenton fluidized bed.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
