A kind of intermittent slurry hydrolysis device, slurry connects the first storage tank and the second storage tank by pipeline respectively, the discharge port of first storage tank and the second storage tank connects the feed inlet of hydrolytic decomposition pot respectively, circulating cooling water tower and cold water pipe are connected with the right side of hydrolytic decomposition pot, flow control valve is installed on cold water pipe, discharge port below hydrolytic decomposition pot is connected with neutralizing tank, aqueous slkali preparing tank is connected with the right side of neutralizing tank, condenser is connected with the left of neutralizing tank and on the left of hydrolytic decomposition pot, gas collection tank is connected with the left of condenser, pot bottom is neutralized and is connected with wastewater collection pond.First storage tank and the second storage tank fill and empty in turn slurry, while not influencing continuously to discharge slurry, batch process slurry, significantly improve the recovery utilization rate of silicon tetrachloride, reduce the dosage and waste water quantum of output of alkali, effectively reduce cost, add economic benefit.
Description
Technical field
The utility model belongs to field, and in particular to a kind of intermittent slurry hydrolysis device.
Background technology
A kind of slurry containing silicon tetrachloride can be produced in polysilicon production process, silicon tetrachloride therein is can to recycle profit
, popular continuously the technology of slurry discharge hydrolysis currently on the market, there are obvious drawback for it：First, portion is taken away in continuous discharge
Divide silicon tetrachloride, cause to waste；Two are the increase in the usage amount of alkali, add cost, and three are the increase in the quantum of output of waste water, no
Beneficial to environmental protection.
The content of the invention
In view of the deficienciess of the prior art, the utility model offer is a kind of environmental-friendly, high financial profit intermittent
Slurry hydrolysis device.
The utility model is achieved through the following technical solutions：
A kind of intermittent slurry hydrolysis device, slurry connect the first storage tank and the second storage tank, institute by pipeline respectively
The discharge port for stating the first storage tank and second storage tank connects the feed inlet of hydrolytic decomposition pot respectively, connection on the right side of the hydrolytic decomposition pot
There are circulating cooling water tower and cold water pipe, flow control valve is installed on the cold water pipe, the discharge port below the hydrolytic decomposition pot connects
Neutralizing tank is connected to, aqueous slkali preparing tank is connected with the right side of the neutralizing tank, is connected on the left of the neutralizing tank with hydrolytic decomposition pot left side
Condenser is connected to, gas collection tank is connected with the left of the condenser, the neutralization pot bottom is connected with wastewater collection pond.
Pressure monitor is installed, the pressure monitor is electrically connected with the flow control valve in the hydrolytic decomposition pot.
Pipeline pump is installed on the feed inlet pipeline of the hydrolytic decomposition pot.
PH detection devices are installed in the neutralizing tank.
Compared with prior art, the beneficial effects of the utility model are：First storage tank fills in turn with the second storage tank
With emptying slurry, while not influencing continuously to discharge slurry, batch process slurry, significantly improves the recycling of silicon tetrachloride
Rate, reduces the dosage and waste water quantum of output of alkali, effectively reduces cost, add economic benefit.
