Embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described.
As shown in Figures 1 to 4, the present invention includes aggregate bin, drying, deduster, and aggregate bin passes through aggregate transloading equipment
Drying is connected, deduster includes removing dirt cup 1 and induced duct, except dirt cup 1 is by induced duct connection drying, in addition to dirt cup 1
Sidewall sheath is provided with water tank 2, the bottom plate of aggregate bin and is provided with circulating water line 3, and the delivery port of water tank 2 is connected to by water pump 4
The water inlet of circulating water line 3, the delivery port of circulating water line 3 connects the water inlet of water tank 2 by return pipe.
During work, the high-temperature tail gas produced in drying is delivered to and removed except dirt cup 1 is interior by deduster by induced duct
Dirt processing, tail gas outer row or the progress two-stage dust removal processing again after removing dust processing, and the dust produced then can typically pass through
Conveying worm 8 is focused on after collecting.Except the lateral wall observed temperature of dirt cup 1 is up to 180 degrees Celsius, the present invention passes through water tank
Water in 2 is reclaimed to the waste heat except dirt cup 1, heat then is delivered into aggregate bin bottom plate by circulating water line, to aggregate
Aggregate in storehouse is preheated, and lifts aggregate temperature, and the moisture progress in aggregate is partially dried, makes aggregate in drying
In heat time reduce, reach the reduction heat time, reduce the purpose that uses of fuel.
Except the quantity of dirt cup 1 can be multiple, each lateral wall except dirt cup 1 is arranged between water tank 2, water tank 2 respectively to be passed through
Mutual water service pipe 5 is connected, and it is circulatory system service that an integrated water tank is formed after connection.In this case, to make full use of
Waste heat, the water inlet of water tank 2 is arranged on a water tank, and delivery port is arranged on another water tank；To make the cold water load in water tank
Accelerate to exchange heat with hot water load, the mutual in the vertical direction of water service pipe 5 sets many, and every mutual water service pipe 5 is horizontally disposed with.In this reality
Except the quantity of dirt cup 1 is two in example, mutual water service pipe 5 is set respectively in top and bottom.
The shape of water tank 2 is with except the profile of dirt cup 1 is adapted, generally removing dirt cup 1 preferably cylindrical shape, water tank 2 in the present invention
Correspondingly in annular or fan annular.When water tank 2 for fan annular when, can facilitate water tank 2 is carried out it is prefabricated, then again with it is existing
Except dirt cup 1 is assembled.
For convenience of control circulating water flow, water pump 4 is connected on the main pipeline of the water inlet of circulating water line 3 and is provided with valve
6。
To make high-temperature water fully be exchanged heat with bottom plate, the serpentine-like distribution of circulating water line 3.
