The disadvantages of.
Utility model content
The utility model in view of the deficiency of the prior art, provides a kind of waste-heat recovery device of coal-burning boiler.
The technical solution that the utility model solves above-mentioned technical problem is as follows: a kind of waste-heat recovery device of coal-burning boiler,
It is characterized in that, including circular cylinder body, upper cover and lower head；The upper cover, lower head airtight connection are in the circle
Shape cylinder both ends；
Upper perforated plate, lower part are equipped with equipped with lower perforated plate on the top of circular cylinder body, are set between the upper perforated plate and lower perforated plate
There is partition, the partition will be divided into air cavity and lumen in circular cylinder body；It is equipped in the lumen and is connect with upper perforated plate, lower perforated plate
Multiple rows of water pipe；It is connected with water inlet pipe on the upper cover, forms intake antrum between the upper perforated plate and upper cover；The lower head
On be connected with drainpipe, form water storage cavity between the lower perforated plate and lower head；
The two sides of the circular cylinder body are equipped with air inlet and air outlet；
The deflector parallel with the partition is additionally provided in the lumen；
Wherein, the partition top is fixedly connected with upper perforated plate, and there are air flues between described the lower partition and lower perforated plate.
The utility model has the beneficial effects that:
In the utility model, by the way that parallel staggered partition and deflector is arranged, so that flue gas is in circular cylinder body inner curve
Operation, increases the contact area of water pipe and flue gas；High temperature heat is transmitted the water in feed pipe by flue gas, and the hot water of discharge can be with
For heating etc., the purpose of waste heat recovering energy conserving is realized；Flue-gas temperature reduces, and achievees the purpose that flue gas minimum discharge.
Based on the above technical solution, the utility model can also do following improvement.
Further, the deflector includes the first deflector and the second deflector；The lower part of first deflector is under
Tube sheet is fixedly connected, and there are air flues between top and upper perforated plate；The top of second deflector is fixedly connected with upper perforated plate, under
There are air flues between portion and lower perforated plate.
Beneficial effect using above-mentioned further scheme is the partition being successively staggered in parallel, the first deflector and
Two deflectors so that flue gas from top to bottom, lateral orbital movement from bottom to up again, so that multiple rows of water pipe is more contacted high temperature cigarette
Gas, so that water is heated evenly.
Further, water inlet valve and a drain valve are respectively equipped on the water inlet pipe and drainpipe.
Beneficial effect using above-mentioned further scheme is, by controlling the switch of water inlet valve and a drain valve, further to control
Retention time of the water processed in water pipe, and then improve water temperature.
