Description

Technical Field

[0002] As steel companies accelerate their efforts to achieve Class A environmental protection, in order to meet the requirements of ultra-low emissions of organized and unorganized emissions of atmospheric pollutants, steel companies are strengthening dust collection in the workshop environment and at workstations. Among them, the most difficult dust collection is in the slag primary processing workshop.

[0003] The primary treatment processes for steel slag mainly include hot stewing, hot pouring and roller hot stewing. Among them, the hot pouring method produces large and dispersed dust. The current hot pouring process mainly involves pouring slag, stewing slag with water, turning slag and pouring slag in a hot pouring pool. A large amount of dust-containing water vapor will be generated in the entire system process. Due to the limitation of dust collection in the pool body, a large amount of dust will overflow even if the hot pouring pool is equipped with an on-site workstation cover, which increases the difficulty of dust collection.

[0004] The scattered dust will permeate the entire workshop. Considering that the original factory steel structure suffers from severe daily water vapor corrosion, and the factory roof is also a light steel structure that does not have the load-bearing capacity, if dust suction is added to the top of the factory, it is necessary to increase the air suction volume, evaluate the factory structure and reinforce the factory, etc., which requires a large investment cost.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 The utility model provides a technical solution of a tipping dust collecting hood with a dust reduction function, a tipping dust collecting hood with a dust reduction function, comprising a flip-type slag pool dust collecting hood 1, the flip-type slag pool dust collecting hood 1 is provided with a dust reduction system, the dust reduction system comprises a plant area compressed air system 11 and a system process water tank 12, the plant area compressed air system 11 comprises a compressed air storage tank 2, the system supporting the compressed air storage tank 2 ensures the stability of the compressed air flow and pressure, the compressed air storage tank 2 is connected with a compressed air pipeline 3, the compressed air pipeline 3 is connected with several slag pools in the flip-type slag pool dust collecting hood 1, and a compressed air metering and distribution module 6 is provided on the compressed air pipeline 3.

[0022] See also Figure 1 A water supply pump 4 is provided in the process water tank 12 of the system, and the supporting water supply pump 4 ensures the stability of the flow and pressure of the atomizing water. A water pipe 5 is provided on the water supply pump 4, and the water pipe 5 is connected with several slag pools in the overturnable slag pool dust collecting hood 1. A water metering distribution module 7 and a control gate are provided on the water pipe 5. The water metering distribution module 7 also has the function of adjusting the flow and pressure, and runs synchronously with the compressed air system.

[0023] See also Figure 1 The compressed air pipe 3 and the water pipe 5 are both provided with a plurality of dual-fluid nozzles 8 in the parts located in the overturnable slag pool dust collecting hood 1, and the plurality of dual-fluid nozzles 8 cooperate with the slag pool.

[0024] See also Figure 1 The slag pool is provided with a plurality of multi-probe dust detectors 9, and the dust reduction system also includes a control system 10. The multi-probe dust detectors 9, the water supply pump 4, the compressed air metering and distribution module 6 and the water metering and distribution module 7 are all electrically connected to the control system 10.

[0025] When in use, the flip-type slag pool dust collecting hood 1 operates throughout the entire process of slag pouring, slag boiling, slag turning and watering, and slag transportation during the hot pouring of steel slag. The two processes of slag boiling and slag turning can be carried out under the dust collection hood, and the dust collection effect is better. During the two processes of slag pouring and slag transportation, the flip-type slag pool dust collecting hood 1 needs to be fully opened to the maximum inclination angle. At this time, the dust collection effect is not good, and dust will overflow. At this time, the dust reduction system can be turned on in these two sections according to the working time to play a dust reduction role, reduce dust overflow, and improve the workshop environment.

[0026] During the slag pouring process, dust will overflow when the slag basin / slag pot pours the steel slag. Because the multi-probe dust detector 9 will set a probe at a suitable position in each slag pool, when the slag pool overflows during the slag pouring process, when the probe detection value exceeds the standard, the signal will be transmitted to the control system 10. After receiving the alarm signal, the control system 10 will control the compressed air metering and distribution module 6 and the water metering and distribution module 7 to open the control valves of the compressed air pipeline 3 and the water pipeline 5 of the corresponding slag pool, and the compressed air and water will enter the flip-type slag pool dust collecting hood 1 and be atomized by the dual-fluid nozzle 8, thereby playing a dust reduction role.

[0027] After the hot pouring of steel slag is completed, the slag needs to be dumped and transported out. During the slag dumping and transportation process, some dust will be generated during the forklift loading process. The multi-probe dust detector 9 will again transmit the value exceeding the standard signal to the control system 10. After receiving the alarm signal, the control system 10 will control the compressed air metering and distribution module 6 and the water metering and distribution module 7 to open the control valves of the compressed air pipeline 3 and the water pipeline 5 of the corresponding slag pool, and the compressed air and water will enter the flip-type slag pool dust collecting hood 1 and be atomized by the dual-fluid nozzle 8, thereby playing a dust reduction role.

[0028] In order to ensure the stable operation of the dust suppression system, the system is equipped with a compressed air storage tank 2 to ensure the stability of the compressed air flow and pressure, and a water supply pump 4 to ensure the stability of the flow and pressure of the atomizing water.

[0029] The compressed air metering and distribution module 6 has the function of regulating flow and pressure. It is equipped with corresponding branches according to the number of hot splash pools, and several branches can be opened at the same time according to the operating conditions. The start and stop of the entire system is controlled by the control system 10 according to the parameter signal of the multi-probe dust detector 9. The water metering and distribution module 7 also has the function of regulating flow and pressure, and runs synchronously with the compressed air system.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
