Connection；Water dispenser is connected to the water outlet of each heat exchanger tube out；Spray equipment is arranged in purifying box, is used for purifying smoke.
However the flue gas of the device is exchanged heat with the water in recycling bins, utilization rate of waste heat is lower in recycling bins.
Summary of the invention
To solve the above-mentioned problems, the utility model devises a kind of Novel flue gas waste-heat recovery device, utilization rate of waste heat
Height, structure is simple, easy to use, also avoids air pollution, has saved energy.
The technical solution of the utility model are as follows:
A kind of Novel flue gas waste-heat recovery device, including recycling bins, it is described if being equipped with dry flue gas branch pipe in the recycling bins
The recycling bins are stretched out at the both ends of flue gas branch pipe, and the arrival end of the flue gas branch pipe is connected with flue gas main pipeline, described
Recycling bins are provided with heat-exchanging water, to make flue gas carry out thermal effect by the heat-exchanging water in flue gas branch pipe and recycling bins, due to cigarette
If gas has been distributed in dry flue gas branch pipe, heat exchange area is increased, improves heat exchange efficiency, utilization rate of waste heat is high, saves
Energy.
Further, the flue gas branch pipe is straight pipeline, screwed pipe or bellows, preferably screwed pipe or bellows, is increased
Add duct length, further improves utilization rate of waste heat.
Further, the surface of the flue gas branch pipe is equipped with heat exchange fin, further improves heat exchange efficiency.
Further, the bottom of the recycling bins is equipped with water inlet, and top is equipped with water outlet, flows water from bottom to top,
Endothermic effect is good.
Further, the water outlet end is equipped with temperature sensor, can also be connected by circulating pump with the water inlet
It is logical, and it is equipped with valve, it realizes the circulation heat absorption of water, is reasonably selected according to the water temperature of water outlet, fully absorb heat.
Wherein, the output end of the temperature sensor is electrically connected with the input terminal of controller, the output end of the controller
It is connected with valve control, is decided whether according to the detection numerical value of temperature sensor by controller come the opening and closing of control valve
Carry out cycle heat exchange.
Further, the arrival end of the flue gas branch pipe is equipped with strainer, realizes the filtering to flue gas, purifying smoke.
Further, the outlet end of the flue gas branch pipe is goed deep by pipeline to the bottom of cleaned water tank, by cleaned water tank
Flue gas after heat exchanging is purified, and structure is simple, easy to use.
Working principle: high-temperature flue gas proceeds to flue gas branch pipe by the distribution of flue gas main pipeline, since flue gas branch pipe is located at recycling
In case, to make the heat-exchanging water in the high-temperature flue gas and recycling bins in flue gas branch pipe carry out heat exchange, since smoke distribution arrives
If in dry flue gas branch pipe, increasing heat exchange area, the flue gas after heat exchange is entered in cleaned water tank by pipeline, by purified water
Case carries out absorption evolution heel row to flue gas and enters atmosphere.
Utility model has the advantages that utilization rate of waste heat is high, structure is simple, easy to use, also avoids air pollution,
Energy is saved.
The utility model is described in further detail with reference to the accompanying drawings and examples.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Specific embodiment
The preferred embodiment of the utility model is illustrated below, it should be understood that preferred embodiment described herein
It is only used for describing and explaining the present invention, is not used to limit the utility model.
Embodiment 1
As shown in Figure 1, a kind of Novel flue gas waste-heat recovery device, including recycling bins 1, the recycling bins 1 are interior equipped with several
The recycling bins, and the arrival end of the flue gas branch pipe 2 and flue gas master are stretched out in flue gas branch pipe 2, the both ends of the flue gas branch pipe 2
Pipeline 3 is connected, and the recycling bins 1 are provided with heat-exchanging water, so that flue gas be made to pass through the heat-exchanging water in flue gas branch pipe and recycling bins
It carries out thermal effect and improves heat exchange efficiency if increasing heat exchange area since smoke distribution is into dry flue gas branch pipe, it is remaining
Heat utilization efficiency is high, has saved energy.
The flue gas branch pipe 2 is straight pipeline, screwed pipe or bellows, preferably screwed pipe or bellows, increases pipeline
Length further improves utilization rate of waste heat.
The surface of the flue gas branch pipe 2 is equipped with heat exchange fin, further improves heat exchange efficiency.
