Description
Technical field
This utility model relates to coal dust explosion-proof technology field, particularly relates to one and utilizes clean flue gas to do
The coal dust storage system of inert protective gas.
Background technology
In high-efficiency pulverized coal furnace system, fuel coal dust is usually first transported to one and can store and can hold
In the pulverized coal warehouse of continuous rationing, for boiler combustion.During coal dust stores, the especially summer
Ji Gaowen days, along with the rising of temperature, coal dust may spontaneous combustion in pulverized coal warehouse, thus dress can be made
Put interior oxygen amount to reduce, produce carbon monoxide, and then cause the danger that blast occurs, so needing one
The noble gas not fired does protective gas, and one is to stop spontaneous combustion to coal dust reducing temperature for preventing, and two is to make coal dust and oxygen
Air bound is exhausted, prevents blast, and at present, the protective gas of domestic use is usually nitrogen, is to pass through space division
Device is produced, and adds a set of space division system and nitrogen storage tank, produces relatively costly.
Utility model content
The purpose of this utility model is to provide the coal dust utilizing clean flue gas to do inert protective gas to deposit
Storage system, to solve the problems referred to above.
This utility model provides a kind of clean flue gas and does the system of inert protective gas, including: flue gas
Inertia protection it is provided with between processing means and smoke discharging device, flue gas processing device and smoke discharging device
Gas branch road and smoke evacuation branch road, inert protective gas branch road is provided with the first regulation valve and cooling and dehumidifying device,
Flue gas processing device and the first regulation valve connect, and the first regulation valve is connected with cooling and dehumidifying device, and cooling removes
Wet device connects pulverized coal warehouse.
Further, smoke evacuation branch road is provided with the second regulation valve, and the second regulation valve is connected with smoke discharging device.
Further, flue gas processing device includes the coal-powder boiler being connected with pulverized coal warehouse, pulverized coal warehouse and coal dust
Being provided with aerator between stove, coal-powder boiler connects cleaner unit, and cleaner unit connects desulfurizing tower, and desulfurizing tower connects and draws
Blower fan, air-introduced machine and the first regulation valve and the second regulation valve connect.
Further, smoke discharging device is chimney.
Compared with prior art, the beneficial effects of the utility model are: by increasing after flue gas processing device
Add inert protective gas branch road, it is provided that inert protective gas to pulverized coal warehouse, not only prevent coal dust from
Combustion and blast, and without increasing space division system and nitrogen storage tank, reduce system cost.
Accompanying drawing explanation
Fig. 1 is the knot that the coal dust that this utility model utilizes clean flue gas to do inert protective gas stores system
Structure schematic diagram.
Detailed description of the invention
Below by specific embodiment and combine accompanying drawing and this utility model is done further retouch in detail
State.
Shown in ginseng Fig. 1, Fig. 1 is that this utility model utilizes clean flue gas to do the coal dust of inert protective gas
The structural representation of storage system.
This utility model provides a kind of clean flue gas and does the coal dust storage system of inert protective gas, bag
Include: be provided with between flue gas processing device and smoke discharging device, flue gas processing device and smoke discharging device
Inert protective gas branch road and smoke evacuation branch road, inert protective gas branch road is provided with the first regulation valve 71 and cold
But dehydrating unit 9, flue gas processing device and the first regulation valve 71 connect, the first regulation valve 71 and cooling
Dehydrating unit 9 connects, and cooling and dehumidifying device 9 connects pulverized coal warehouse 1.
This system is by increasing inert protective gas branch road after flue gas processing device, it is provided that inertia protection gas
Body, to pulverized coal warehouse, not only prevent spontaneous combustion and the blast of coal dust, and without increase space division system and
Nitrogen storage tank, reduces system cost.
In the present embodiment, smoke evacuation branch road is provided with the second regulation valve 72, and the second regulation valve 72 is arranged with flue gas
Put device to connect.
In the present embodiment, flue gas processing device includes the coal-powder boiler 3 being connected with pulverized coal warehouse 1, coal dust
