Description

Technical Field

[0001] The utility model relates to the technical field of dust removal in thermal power plants, in particular to a dust collector for loading wet ash from an ash bin in a thermal power plant. Background Art

[0002] Thermal power plants use fossil fuels (such as coal, natural gas, or oil) to generate steam, which in turn drives turbines to generate electricity. Loading wet ash from ash silos is a critical operation in thermal power plants. This involves loading wet ash (slag, fly ash, etc.) stored in ash silos into transport vehicles or other equipment. Dust is generated during the loading process, requiring dust removal.

[0003] A search revealed a thermal power plant dust collector with publication number CN222173546U, comprising a dust collector housing. The upper side of the dust collector housing is connected to an exhaust pipe, a fan is installed in the exhaust pipe, a water trough is provided inside the lower end of the dust collector housing, and an air inlet pipe is connected to the water trough. The lower left end of the water trough is connected to a drain pipe, and the upper right end of the water trough is connected to a water supply pipe. A first motor is installed at the lower right side of the dust collector housing, the output end of the first motor is connected to a first rotating rod, and a first filter plate is installed on the outer side of the first rotating rod. The dust collector housing has a through hole. The thermal power plant dust collector first draws flue gas into the water trough, where the water in the water trough cools the flue gas. The dust is initially trapped in the water by the first filter plate, and the flue gas is then discharged upwards moistly for interception and filtration. This prevents dust from floating and re-combining with the flue gas during dust cleaning, thereby improving the efficiency of flue gas dust removal.

[0004] The device in this patent cannot detect the weight of dust inside the dust collector during use, and the staff cannot judge whether the dust needs to be cleaned. It is easy for multiple treatments and untimely treatment to affect the dust removal efficiency, and its practicality is low. Utility Model Content

[0029] The following is combined with Figure 1-4 The utility model is further described.

[0030] In order to solve the problems existing in the background technology, this application proposes the following technical solutions:

[0031] A dust collector for loading wet ash from an ash silo in a thermal power plant, comprising: an ash silo main body 1, a silo top dust collector 3, a dust removal structure 4, and a detection component 5;

[0032] The ash bin body 1 is internally provided with a vehicle body 2;

[0033] The top dust collector 3 is installed on the top of the ash silo body 1;

[0034] The dust removal structure 4 includes a pump body 401 installed inside the dust collector 3 on the top of the silo by bolts, a separation box 402 installed inside the dust collector 3 on the top of the silo, and a purification box 403 installed at the bottom of the separation box 402;

[0035] The two ends of the pump body 401 are connected to the collection bucket in the ash storage body 1 through pipes and are connected to the separation box 402 through a hose. The separation box 402 is connected to the purification box 403 through a hose. A through hole is opened on one side of the separation box 402. The moisture in the air and the particles will be separated from the air. A filter is installed on the top to filter the air discharged from the separation box 402.

[0036] A purification layer is installed inside the purification box 403, and an air outlet pipe 6 is installed on one side of the purification box 403.

[0037] like Figure 1-4 As shown, the detection component 5 is installed at the bottom of the separation box 402 , and the detection component 5 is used to detect the weight of the dust inside the separation box 402 .

[0038] The detection assembly 5 includes a supporting structure 501 installed on both sides of the separation box 402 and a detection structure 502 installed at the bottom of the separation box 402. The supporting structure 501 includes a guide column 5011 fixedly welded to the top of the purification box 403, a guide plate 5012 slidably connected to the guide column 5011, and a reset spring 5013 welded to the bottom of the guide plate 5012 and the top of the purification box 403. The guide plate 5012 is fixedly welded to both sides of the separation box 402, and the reset spring 5013 is sleeved on the outside of the guide column 5011.

[0039] Furthermore, the detection structure 502 includes a sensing plate 5021 installed at the bottom of the separation box 402 and a sensing base 5022 installed at the top of the purification box 403 , and the sensing plate 5021 cooperates with the sensing base 5022 .

[0040] Working principle: When in use, wet ash is loaded into the ash bin main body 1 through the vehicle body 2. Dust is generated during the operation. When passing through the main body, the collection bucket in the ash bin main body 1 generates suction to absorb wet ash and other particulate matter in the air. The wet ash and other particulate matter enter the separation box 402. There is moisture in the dust, and the particulate matter falls to the bottom of the separation box 402. The air passes through the filter screen and the hose on one side and enters the purification box 403. The toxic substances in the air are purified by the purification layer plate, and the treated air is discharged through the outlet pipe 6.

[0041] Dust accumulates in the separation box 402, and the weight of the separation box 402 increases. The separation box 402 drives the guide plate 5012 to move. The guide plate 5012 slides on the guide column 5011 and squeezes the return spring 5013. The separation box 402 drives the sensing plate 5021 to move toward the sensing seat 5022. When the sensing plate 5021 contacts the sensing seat 5022, the alarm in the control room in the ash bin main body 1 sounds an alarm to remind the staff to clean the dust in the separation box 402, so as to avoid affecting the dust removal work, avoid the situation where the staff cleans it multiple times or does not clean it in time, and improve work quality and work efficiency.
