And the furnace temperature of the coil pipe that inlet channel on-line production is delivered in ingot casting furnace body, effectively reduction ingot furnace, the high-temperature water after heating lead to
Obtained after crossing plate type heat exchanger heat exchange in 38~40 degrees Celsius of current time soaking and washing pond, to being placed on the more of soaking and washing pond
Crystal silicon material carries out immersion and goes sour work, and the utility model reduces work furnace temperature, saves the soak time of polycrystalline silicon material again,
Reduce the waste of water resource.
Formed preferably, the coil pipe coils bending by one whole metal tube, including column coil pipe and positioned at column
The plane curved tube of coil pipe bottom, the column coil pipe are close to the setting of ingot casting furnace sidewall, and the furnace bottom that plane curved tube is close to ingot furnace is set
Put.
Preferably, the coil pipe is completed to fix by setting between support and ingot furnace.
Preferably, the support has four and Z-shape, described support one end is fixed on the madial wall of ingot furnace
On, the other end is fixed on the furnace bottom of ingot furnace.
Compared with prior art, the beneficial effects of the invention are as follows：Water in soaking and washing pond by the first water pump and is entered
The coil pipe that waterpipe on-line production is delivered in ingot casting furnace body, effectively reduces the furnace temperature of ingot furnace, and the high-temperature water after heating passes through plate
Obtain 38~40 degrees Celsius of current after the heat exchange of formula heat exchanger to return in soaking and washing pond, the polysilicon to being placed on soaking and washing pond
Material carries out immersion and goes sour work, and the utility model had both reduced work furnace temperature, saved the soak time of polycrystalline silicon material again, reduces
The waste of water resource.
