Description

Unloading dust suppression device for slag bin

Technical Field

The utility model relates to an environmental protection dust suppression device, in particular to sediment storehouse uninstallation dust suppression device.

Background

The slag bin is a powder slag buffer bin of a coal-fired power plant, and after coal is combusted, gas waste and solid waste are generated, wherein the solid waste is powder slag. The powder slag is cooled by the slag cooler and then transferred to a slag bin for caching, and finally is transported to a designated place for processing through a special slag transport vehicle so as to prevent the environment from being polluted. In the process of unloading and loading the slag bin, the dust in the slag unloading chamber is large, so that the observation and operation are not facilitated, and the health of workers is influenced.

At present, a bag-type dust collector is generally adopted for dust removal, a certain dust removal effect can be achieved in a short time, but the bag-type dust collector continuously descends after running for a period of time, so that the bag-type dust collector is not needed to be placed finally. Therefore, the problem of dust emission during unloading of the slag bin cannot be solved well.

Disclosure of Invention

The utility model aims at providing a sediment storehouse uninstallation dust suppression device does not need water and electricity, utilizes chimney effect and dust absorption principle, solves the problem of sediment storehouse uninstallation raise dust well.

In order to achieve the above purpose, the technical scheme of the utility model is that:

the slag bin unloading dust suppression device is arranged on the top of the slag bin and comprises an air outlet, a dust adsorption rubber strip, a dust suppression device cavity, a partition plate, a herringbone slope, an air inlet, a soft silica gel sealing curtain, an ash discharge port, the slag bin, an air exhaust pipe, an air inlet pipe and a slag discharge chamber, wherein the dust adsorption rubber strip is hung in the middle of the dust suppression device cavity; the partition plate is arranged in the dust suppression device cavity and is opposite to the air inlet; the soft silica gel sealing curtains are hung on two sides of the herringbone slope, and the lower ends of the soft silica gel sealing curtains are in contact with the inclined wall of the cavity of the dust suppression device; the ash discharge port is communicated with the slag bin.

The lower end of the air exhaust pipe is connected with an air outlet, the upper end of the air exhaust pipe extends out of the roof and is at least 300mm higher than the roof, and the top of the air exhaust pipe is provided with a rain-proof cap.

The lower end of the air inlet pipe extends into the top of the slag discharging chamber, and the upper end of the air inlet pipe is connected with an air inlet.

The beneficial effects of the utility model.

The utility model discloses do not need water and electricity, utilize chimney effect and dust absorption principle, solve the problem of sediment storehouse uninstallation raise dust well. Not only prevents dust from polluting the environment, but also ensures the personal benefits of post workers.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a schematic view of the working state of the present invention.

In the figure: 1. an air outlet; 2. a dust adsorption rubber strip; 3. a dust suppression device cavity; 4. a partition plate; 5. a herringbone slope; 6. an air inlet; 7. a soft silica gel sealing curtain; 8. an ash discharge port; 9. a slag bin; 10. an air exhaust duct; 11. the slag bin unloads the dust suppression device; 12. an air inlet pipe; 13. a slag discharging chamber.

Detailed Description

Referring to the drawings, the slag bin unloading dust suppression device of the utility model is arranged on the top of the slag bin and comprises an air outlet 1, a dust adsorption rubber strip 2, a dust suppression device cavity 3, a partition plate 4, a herringbone slope 5, an air inlet 6, a soft silica gel sealing curtain 7, an ash discharge port 8, a slag bin 9, an air exhaust duct 10, an air inlet duct 12 and a slag discharge chamber 13, wherein the dust adsorption rubber strip 2 is suspended in the middle of the dust suppression device cavity 3; the partition plate 4 is arranged in the dust suppression device cavity 3 and is opposite to the air inlet 6; the soft silica gel sealing curtains 7 are hung on two sides of the herringbone slope 5, and the lower ends of the soft silica gel sealing curtains are in contact with the inclined wall of the cavity 3 of the dust suppression device; the ash discharge port 8 is communicated with the slag bin 9.

In this embodiment, the lower end of the exhaust air pipe 10 is connected with the exhaust port 1, the upper end of the exhaust air pipe extends out of the roof and is at least 300mm higher than the roof, and the top of the exhaust air pipe is provided with a rain-proof cap.

In the embodiment, the lower end of the air inlet pipe 12 extends into the top of the slag discharging chamber, and the upper end is connected with the air inlet 6.

As shown in fig. 2, the working process is as follows: because the air exhaust pipe and the air inlet pipe are both connected with the slag bin unloading dust suppression device, a gas channel is formed, and thus, a chimney effect is generated. The gas in the slag discharging chamber enters the air pipe from the bottom opening of the air inlet pipe due to air pressure difference, and goes upward in the air pipe to enter the cavity of the dust suppression device, dust particles in the gas are adsorbed on the dust adsorption adhesive tape under the action of the dust adsorption adhesive tape, and after the dust on the adhesive tape is accumulated to a certain degree, the dust falls off under the action of gravity, is guided along the herringbone slope, and falls into the slag bin from the ash discharge opening. The filtered gas continues to go upwards from the air outlet of the dust suppression device and is exhausted to the outside along the air exhaust pipe.

The utility model discloses implement the back, need not use water and electricity, utilize chimney effect and dust absorption principle, solve the problem of sediment storehouse uninstallation raise dust well. Not only prevents dust from polluting the environment, but also ensures the personal benefits of post workers.
