It affects the surrounding environment, the health of operators again, and there are potential safety and environmental protection hazards such as environmental protection notification incidents, thus affecting the safe and environmental protection operation of the unit's ash removal system. Summary of the Invention

[0003] The purpose of the utility model is to provide a dust removal device for dry ash loading machine in ash silo.

[0004] The above purpose is achieved by the following technical solutions:

[0005] A dust removal device for dry ash loading machine in ash silo, which comprises: a bag filter. A first air extraction port and a second air extraction port are opened at the lower part of the bag filter. The first air extraction port and the second air extraction port are respectively connected to the ash unloading head through air ducts. The small ash hopper of the bag filter is connected to the main ash flushing pipe. A first ash flushing sub-pipe and a second ash flushing sub-pipe are respectively connected to the main ash flushing pipe. The first ash flushing sub-pipe and the second ash flushing sub-pipe are connected to the small ash hopper of the bag filter. An ash flushing valve is installed on the main ash flushing pipe.

[0006] For the dust removal device for dry ash loading machine in ash silo, the bag filter is connected to a dust removal fan.

[0007] For the dust removal device for dry ash loading machine in ash silo, the ash unloading head is connected to the loading machine.

[0008] For the dust removal device for dry ash loading machine in ash silo, the dust removal fan has a capacity of 5.5 kw and a flow rate of 6000 - 6600 m³ / h. Advantageous Effects

[0009] 1. The utility model solves the problems that the dust removal device for dry ash loading machine in the electric bag filter has low treatment efficiency, large dust emission during ash unloading, and affects the surrounding environment, etc. It is a method to improve the environment around the ash silo, improve the health level of operators, prevent environmental protection notification events, etc., and reduce unsafe events in the safe and environmental protection operation of the unit.

[0010] 2. The utility model is based on the transformation of the dust removal device for dry ash loading machine in the ash silo, solves the problem of dust emission during ash unloading in the ash silo, improves the environment around the ash silo, improves the health level of operators, and prevents environmental protection notification events, etc., which affect the safe and environmental protection operation of the unit. Brief Description of the Drawings

[0011] Attached Figure 1 is a schematic structural view of the present utility model.

[0012] Attached Figure 2 is a schematic structural view of the present utility model without the second air extraction port and the second ash flushing sub-pipe.

[0013] In the figure: 1: Bag filter, 2: First air extraction port, 3: Second air extraction port, 4: Ash discharge head, 5: Main ash flushing pipe, 6: First ash flushing sub-pipe, 7: Second ash flushing sub-pipe, 8: Ash flushing valve, 9: Dust removal fan, 10: Bulk loader. Specific implementation mode Embodiment

[0014] A dust removal device for a dry ash bulk loader in an ash silo, which comprises: a bag filter 1, the lower part of the bag filter is provided with a first air extraction port 2 and a second air extraction port 3, the first air extraction port and the second air extraction port are respectively connected with an ash discharge head 4 through air pipes, the small ash hopper of the bag filter is connected with a main ash flushing pipe 5, the main ash flushing pipe is respectively connected with a first ash flushing sub-pipe 6 and a second ash flushing sub-pipe 7, the first ash flushing sub-pipe and the second ash flushing sub-pipe are connected with the small ash hopper of the bag filter, and an ash flushing valve 8 is installed on the main ash flushing pipe. The bag filter is connected with a dust removal fan 9. The ash discharge head is connected with a bulk loader 10. Embodiment

[0015] A dust removal device for a dry ash bulk loader in an ash silo increases the air extraction volume by increasing the capacity of the original dust removal fan with a capacity of 2.2 kw and a flow rate of 3000 m³ / h in the bag filter of the dry ash bulk loader in the ash silo (the original ash silo, the coarse ash silo, and the fine ash silo) to a dust removal fan with a capacity of 5.5 kw and a flow rate of 6000 - 6600 m³ / h. At the same time, on the basis of the original one air extraction port at the lower part of the dust collector, a second air extraction port is added to reduce the dust raising of the ash tank truck during ash unloading. On the basis of the original one ash flushing pipe in the small ash hopper of the dust collector, a first ash flushing sub-pipe and a second ash flushing sub-pipe are added to solve the problem that the dust removal efficiency of the bag filter is reduced due to the small ash hopper of the dust collector being full of ash and submerging the filter bags. The original bag cleaning system and dust removal filter bags are retained.
