Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to a dust removal system for a loading device. Background Art

[0002] As the coking industry faces increasingly stringent environmental protection requirements, it is particularly important to take necessary measures to reduce smoke spillage from dry coke quenching equipment.

[0003] The smoke and dust generated by the existing CDQ system is mainly concentrated in the following three parts: one is the loading device on the top of the CDQ furnace, the second is the discharge port of the circulating fan, and the third is the belt at the bottom of the CDQ furnace. The latter two use dust removal fans to continuously suck the smoke and dust into the dust removal ground station for treatment. In the existing CDQ dust removal system, the dust removal baffle of the loading device is opened during the coke loading process, and the dust removal fan is in a high-speed operation state. At this time, the smoke generated by the coke loading system during coke loading is discharged to the CDQ dust removal system.

[0004] However, the existing loading device adopts a double-layer structure, that is, the upper layer is fixed and the lower layer is movable. If the loading device is well sealed, it can basically meet the environmental protection requirements. However, when the coke can leaves the loading device and the loading device is not completely closed, the gas absorbed by the dust removal pipeline contains a large amount of air in addition to part of the CDQ flue gas, which directly causes the CDQ furnace flue gas to overflow and cause pollution.

[0021] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] like Figure 1-Figure 2 As shown, the utility model provides a dust removal system for a loading device, comprising a plurality of dust removal units 2, one end of the dust removal unit 2 is connected to and communicated with the side wall of the CDQ furnace cone section 1, and the other end of the dust removal unit 2 is connected to and communicated with the CDQ dust removal module, so as to facilitate the exhaust gas in the CDQ furnace to be discharged into the original CDQ dust removal module through the dust removal unit 2. An electric valve 6 is installed on the dust removal unit 2, and the electric valve 6 is electrically connected to the central control room. When the CDQ coke loading is completed, when the elevator is lifted to the upper limit and starts to move, the elevator sends a signal to the central control room that the loading device starts to be closed. After receiving the signal, the central control room controls the electric valve 6 to open and realizes the dust removal of the dust removal unit 2, so as to realize the dust removal inside the CDQ furnace during the closing process of the loading device, improve the dust removal efficiency of the CDQ, avoid the overflow of smoke, and ensure the environmental protection requirements. When the central control room receives the signal that the closing of the loading device is completed, the electric valve 6 is controlled to be closed, so as to realize the automatic opening and closing of the electric valve 6.

[0023] Specifically, the dust removal unit 2 includes a lower transverse section 3, a longitudinal section 4 and an upper transverse section 5 which are connected and communicated in sequence. One end of the lower transverse section 3 is installed on the side wall of the dry quenching furnace cone section 1, the other end of the lower transverse section 3 is installed on the lower end of the longitudinal section 4, the upper end of the longitudinal section 4 is installed on one end of the upper transverse section 5, and the other end of the upper transverse section 5 is installed on the dry quenching dust removal module. The lower transverse section 3, the longitudinal section 4 and the upper transverse section 5 are combined into a dust removal pipeline to guide the flue gas in the dry quenching furnace into the dry quenching dust removal module to avoid the overflow of the flue gas.

[0024] The electric valve 6 is installed on the upper part of the longitudinal section 4, and the electric valve 6 can electrically control whether the flue gas in the dust removal unit 2 flows. When the electric valve 6 is opened, the flue gas can pass through the lower transverse section 3, the longitudinal section 4 and the upper transverse section 5 in sequence and enter the dry quenching dust removal module; when the electric valve 6 is closed, the flue gas will not be discharged because the longitudinal section 4 is blocked.

[0025] A manual valve 7 is installed in the middle of the longitudinal section 4. The manual valve 7 can manually control whether the smoke in the dust removal unit 2 flows. When the electric valve 6 needs to be repaired or replaced, the manual valve 7 can be operated to manually control the flow of the dust removal pipeline.

[0026] A discharge port is provided at the lower part of the longitudinal section 4, and an ash discharge valve 8 for discharging ash is installed at the discharge port to achieve ash cleaning.

[0027] There are two dust removal units 2, and the two dust removal units 2 are symmetrically arranged.
