The invention provides a stereo totally-closed
greening vacuum alkali removing device and an application method thereof. The device is mainly formed by a feedwater control valve (1), an upper layer alkali removing
pipe (2), an upper layer alkali removing
pipe feedwater control valve (3), a lower layer alkali removing
pipe (4), a lower layer alkali removing pipe feedwater control valve (5), a
ponding discharge valve (6), an upper layer alkali removing pipe connecting pipe (7), an upper layer and lower layer alkali removing pipe connecting pipe (8), an upper layer and lower layer alkali removing pipe control valve (9), a lower layer alkali removing pipe connecting pipe (10), a
vacuum pump (11), a single pump control valve (12), a self-drainage control valve (13), a self-flowing port (14), a forced drainage overflow port (15), an external soaking prevention film (16), and
fresh water (17). Beneficial effects of the device are that the structural design is rational and practical, complicated procedures are reduced, and alkali removing is clean and thorough, and wind energy and
solar energy are directly used as power to reduce operational cost, so as to achieve effect of
green power alkali removing.
