Description
Technical field
The utility model belongs to paper technology apparatus field, and in particular to a kind of flue gas cooling treatment device.
Background technique
Equipment needs to discharge a large amount of flue gases in paper-making process, and environment, while flue gas and particle are not only polluted in the discharge of flue gas
When machine is connected, the high-temperature flue gas of discharge easily burns, and aggravates environmental pollution, forms security risk, while slatterning big calorimetric
Can, lack one kind can cooling high temperature flue gas, while using thermal energy device.
Utility model content
The utility model provides a kind of flue gas cooling treatment device, can be to flue gas temperature with high efficiency, and recycles extra thermal energy.
The technical solution adopted in the utility model is：
A kind of flue gas cooling treatment device, including flue and cooling bay have coolant liquid, the flue end in the cooling bay
End is protruded under cooling-liquid level, and roots blower is arranged in flue, filter layer is arranged in the cooling bay, the filter layer is located at cigarette
Between road end and liquid level, cooling bay connects heat-exchanger rig, and the heat-exchanger rig is connected to above filter layer.Flue protrudes into liquid level
Under, the mode that can use water cooling cools down to flue gas, while filtering the particulate matter in flue gas and part pernicious gas, mistake
Filtering layer is set to above flue end, it can it plays a role in filtering, while particulate matter will not be deposited in above filter layer, thus
Filter layer will not be blocked or filtering is laminated to deformation, heat-exchanger rig can make full use of smoke heat energy, carry out to other equipment
Hot water supply or heating.
Preferably, the heat-exchanger rig includes heat exchanger tube and pipe heat exchanger, and the heat exchanger tube is connect with pipe heat exchanger,
Heat exchanger tube setting pump and filter device.Filter device can further filter the impurity in coolant liquid, prevent from generating bad shadow to pump
It rings.
Wherein, the filter device includes shell and filter screen, and the filter screen is tubular, and filter screen is closed at one end, mistake
The strainer other end and filter device opening connect.The filter area of cylindrical filter sieve is bigger, and filter efficiency is high, while to liquid flow
The raw resistance of movable property is smaller.
Further, the filter screen connects flushing pipe.Impurity in the flushable filter screen of flushing pipe extended using week
Phase.
Preferably, the filter layer is porous metals plate.Metal material intensity is higher, can be used for a long time.
Preferably, the filter screen is Fiber Materials.Fiber Materials are finer and closely woven, and filter effect is more preferable.
The utility model can effectively cool down to high-temperature flue gas, and play certain filtration, while can also return
The thermal energy for receiving flue gas, improves the utilization rate of the energy.

As shown in Fig. 1 Fig. 2, roots blower 2, flue 1 is arranged in a kind of flue gas cooling treatment device, including flue 1, flue 1
Cooling bay 3 is connected, coolant liquid 4 is set in cooling bay 3,1 end of flue is protruded into below the liquid level of coolant liquid 4, and cooling bay 3 was arranged
Filtering layer 31, filter layer 31 are located between 1 end of flue and the liquid level of coolant liquid 4, and exhaust outlet 31, filter layer 32 is arranged in cooling bay 3
Use porous sheet metal.
Cooling bay 3 connects heat-exchanger rig, and heat-exchanger rig includes heat exchanger tube 5 and heat exchanger 6, and heat exchanger is pipe heat exchanger,
Heat exchanger tube 5 connects heat exchanger 6 and cooling bay 3, and is connected to 31 top of filter layer of cooling bay 3.Setting filtering dress on heat exchanger tube 5
Set 7 and pump 8.Filter device 7 includes shell 71, shell inlet porting 72 and outlet 73, and filter screen 74, filtering are arranged in shell 71
Net 74 is tubular, and closed at one end, one end is connect with entrance 72, and filter screen 74 is Fiber Materials, and connects 2 flushing pipes 75.
