Abstract

The utility model relates to a dust removal communication device for a group of coal storage silos, comprising: a coal storage silo, an exhaust communication pipe, a forward and reverse explosion-proof fan, and a discharge port; The gas connecting pipe is connected, the exhaust connecting pipe is connected through the forward and reverse explosion-proof fan, and the discharge port is located on the upper end surface of the coal storage silo. The coal storage silo group dust removal communication device utilizes the principle of mutual recovery between the silos storing coal, so that the air from the first silo to the last silo is all connected. In this way, maintenance-free, no pulverized coal loss, and zero pollution are realized.

Description

A dust removal communication device for coal storage silos

technical field

The utility model relates to the technical field of dust removal for coal storage silos, in particular to a dust removal communication device for coal storage silos.

Background technique

In the process of unloading coal to the coal storage silo, due to the large height difference of coal falling, a large amount of coal powder is produced, which will escape through the discharge port and other gaps in the silo. In order to solve the environmental pollution problem of coal powder, dust removal equipment such as electrostatic precipitator and bag filter are usually applied. Although it can meet the environmental requirements, it is greatly restricted in the actual application process due to the shortcomings of the equipment itself. In the early stage of design and construction, electrostatic precipitator and bag filter have high requirements on the structure of the silo due to the large equipment load and large space occupation. After it is completed and used, there are problems such as large power consumption, high operating costs, and difficulty in recycling pulverized coal. Eventually there may be situations where dust removal equipment is unusable or unusable during coal storage.

Utility model content

The purpose of the utility model is to provide a dust removal communication device for coal storage silos that is free of maintenance, has no loss of pulverized coal, and emits zero pollution.

In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: a dust removal communication device for coal storage silos, including: coal storage silos, exhaust communication pipes, forward and reverse explosion-proof fans, and discharge ports; The air outlets on the top of the two coal storage silos are connected through an exhaust communication pipe, and the exhaust communication pipe is connected through a forward and reverse explosion-proof fan. The discharge port is located on the upper end surface of the coal storage silo.

The exhaust communication pipes are connected in an inverted "V" shape.

The diameter of the exhaust communication pipe is 700-1000mm.

The beneficial effect of the utility model is that the coal storage silo group dust removal communication device utilizes the principle of mutual recovery between the silos storing coal, so that the air from the first silo to the last silo is all connected. In this way, maintenance-free, no pulverized coal loss, and zero pollution are realized.

The symbols in the above figure are explained as follows:

1—Coal storage silo; 2—Exhaust connecting pipe; 3—Forward and reverse explosion-proof fan; 4—Discharging port; 5—Discharging trolley.

Detailed ways

The technical scheme of the utility model will be further described below in conjunction with the accompanying drawings through specific embodiments.

A dust removal communication device for a group of coal storage silos, comprising: a coal storage silo 1, an exhaust communication pipe 2, a forward and reverse explosion-proof fan 3, and a discharge port 4; the top air outlets of two adjacent coal storage silos 1 pass through The exhaust connecting pipe 2 is connected, the exhaust connecting pipe 2 is connected through the forward and reverse explosion-proof fan 3, the discharge port 4 is located on the upper end of the coal storage silo 1, and the coal is placed on the upper end of the coal storage silo 1 by the unloading trolley 5. Fall from the discharge port 4 into the coal storage silo 1.

During the unloading process of the coal storage silo, the coal falls into the coal storage silo 1 through the unloading trolley 5 through the discharge port 4, and the displaced air and splashed coal powder enter the adjacent another storage silo through the exhaust connecting pipe 2. coal silo 1, and settle naturally in the adjacent coal storage silo 1, and so on in sequence, so that the air in the first coal storage silo 1 to the last coal storage silo 1 is all connected. The diameter of the exhaust connecting pipe 2 is preferably 800 mm, and it is connected in an inverted "V" shape to prevent coal dust from accumulating in the connecting pipe.
