Description
Technical field
The utility model relates to a kind of polycrystalline silicon production device, and particularly a kind of hydrogenation apparatus utilization heat more than needed that reduces is produced the device of steam.
Background technology
Produce in the polysilicon process at Siemens Method, owing to reduction furnace, hydrogenation furnace need consume a large amount of electric energy aborning, a part is used for satisfying the heat of reaction needed, and the overwhelming majority is used for to material heating in the stove, so that material reaches reaction condition.A heat part is absorbed, and a part is taken away by tail gas, and a part is taken away by the high-temperature water of furnace wall chuck.High-temperature water plays the effect of cooled furnace wall, protection equipment.The heat that high-temperature cooling water is taken away is very high, belongs to the higher heat of quality, has to utilize very much to be worth, and can produce steam, supply with other operation of factory, but this high-temperature cooling water is not utilized fully but, has wasted resource.
As shown in Figure 1, V0802 is a flash tank, and V0803 is the high-temperature water circulating slot.The high-temperature water that returns is controlled by valve, both can get back to V0802 and produce steam, can get back to V0803 again and directly drive circulation by pump.In order to utilize the heat energy flash-off steam, we need control water is got back to V0802.
Theoretically, the high-temperature water that returns is after the V0802 flash distillation, and steam is gone to steam pipe system from the top, the water that condensation is got off from the bottom to V0803.But in fact, back pressure descends suddenly and could produce flash distillation because high-temperature water is returned, formation steam, so the pressure of flash tank is lower than the high-temperature water circulating slot.And the high-temperature water circulating slot is consistent with the actual pressure of high-temperature water, has caused flash tank to produce the water that liquefies behind the steam, can't be pressed onto smoothly from the bottom the circulating slot, and be that the water in the circulating water chennel has been pressed onto flash tank from the bottom on the contrary, make that the liquid level of flash tank is very high.Like this, liquid level is high in the flash tank, does not have the flash distillation space, and high-temperature water can't flash distillation, and heat does not obtain utilizing, and has caused very big waste.
The utility model content
The goal of the invention of the utility model is: the problem to above-mentioned existence, provide a kind of simple in structure, and handiness is quick, and high-temperature cooling water is utilized fully, and the reduction hydrogenation high-temperature water that has reduced the wasting of resources is realized the device of flash distillation.
The technical scheme that the utility model adopts is following:
The reduction hydrogenation high-temperature water of the utility model is realized the device of flash distillation; Comprise flash tank and high-temperature water circulating slot, condensate liquid flows into from the top of flash tank, and the top of said flash tank is connected to main steam range; And the bottom is connected to trench; Conducting between the bottom of the bottom of said flash tank and high-temperature water circulating slot, said high-temperature water circulating slot is connected to trench from its side and bottom, and the pipe network desalted water is from the inflow of high-temperature water circulating slot; High-temperature water flows out from the bottom of high-temperature water circulating slot; Behind reduction furnace and hydrogenation furnace, flow into the top and the flash tank side bottom of high-temperature water circulating slot, pass through the balance pipe conducting between the top of the top of said flash tank and high-temperature water circulating slot.
Owing to adopted said structure, flash tank with high-temperature water circulating slot top, increased a balance pipe, the top of two grooves is communicated with, balance the pressure of two grooves.After adding this balance pipe, when the pressure of circulating slot raises, when the hydraulic pressure of flash tank was not come, the pressure of circulating slot was unloaded to flash tank by balance pipe automatically, reduced the pressure of circulating slot after, water just can successfully be got back to circulating slot from flash tank naturally.Since the flash tank top had the space, the high-temperature water that therefore returns also just can flash distillation.The reduction hydrogenation high-temperature water of the utility model is realized the device of flash distillation, can produce steam, energy savings, and simple in structure, handiness is quick, and high-temperature cooling water is utilized fully.
In sum, owing to adopted technique scheme, the beneficial effect of the utility model is:
1. the reduction hydrogenation high-temperature water of the utility model is realized the device of flash distillation, and simple in structure, handiness is quick, and can produce steam, energy savings;
2. the reduction hydrogenation high-temperature water of the utility model is realized the device of flash distillation, can high-temperature cooling water be utilized fully, has reduced the waste of the energy, is beneficial to popularization.
