Abstract
The invention provides a production process of a band type vacuum filter capable of saving water and is used for solving the problem that the existing band type vacuum filter wastes water resource in operation. New hot water is used in secondary washing only, filtrate after the secondary washing is used for regenerating cleaning water by virtue of filter cloth, then returning the cleaning water as water for primary washing by virtue of a pump, and filtrate after the primary washing is sent to an evaporation device; and the following conditions are met in operation, feeding flow is 27-30m<3>/h, feeding liquid-solid ratio is 2.2-2.15, a feeding temperature is 45-52 DEG C, speed of a track is 8-15m/min, and vacuum degree is 0.03-0.05MPa. The production process of the band type vacuum filter capable of saving water has a good solid-liquid separation effect, and water is saved, so the cost is greatly saved.
Description
Technical field
The present invention relates to the filter field, especially a kind of belt vacuum filter production technology that conserves water.
Background technology
Belt vacuum filter is a kind of liquid-solid separation equipment of novel, efficient, continued operation, have that dehydrating effect is good, the unit are treating capacity is large, discharging thoroughly, filter cloth is easy to cleaning, long service life, be convenient to the characteristics such as maintenances, at home and abroad for industries such as mine, metallurgy, chemical industry, environmental protection.
Belt vacuum filter is since dropping into use, and required filter cloth regeneration water consumption is larger in the production run.Cause on the one hand the water system balance difficulty, wash water band material need be recycled on the other hand, has greatly restricted the development of belt vacuum filter.
Summary of the invention
In order to solve existing belt vacuum filter at work to the problem of the waste of water resource, the invention provides a kind of belt vacuum filter production technology that conserves water, not only good effect of separating solid from liquid, and water-saving has been saved cost greatly.
Described a kind of belt vacuum filter production technology that conserves water, it is characterized in that: the new water that only when washing for the second time, uses heat, filtrate after the secondary washing is used as the filter cloth regeneration water for cleaning, then water for cleaning is returned as the once washing water with pump, the filtrate behind the once washing is sent to evaporation; Simultaneously, when guaranteeing work, the pan feeding flow is 27 ~ 30m
3/ h; The pan feeding liquid-solid ratio is 2.2 ~ 2.15; The pan feeding temperature is 45 ~ 52 ℃; Crawler belt speed is 8 ~ 15m/min; Vacuum is 0.03 ~ 0.05MPa.
The invention has the beneficial effects as follows: not only good effect of separating solid from liquid, and water-saving, saved greatly cost.
The specific embodiment
In actual production, adopt a kind of belt vacuum filter production technology that conserves water, only when washing for the second time, use the new water of heat, filtrate after the secondary washing is used as the filter cloth regeneration water for cleaning, then water for cleaning is returned as the once washing water with pump, the filtrate behind the once washing is sent to evaporation; Simultaneously, when guaranteeing work, the pan feeding flow is 27 ~ 30m
3/ h; The pan feeding liquid-solid ratio is 2.2 ~ 2.15; The pan feeding temperature is 45 ~ 52 ℃; Crawler belt speed is 8 ~ 15m/min; Vacuum is 0.03 ~ 0.05Mpa.Washing lotion with minimum obtains more excellent detersive efficiency, and reaches production requirement.
Be about 500,000 yuan for 10000 t aluminium hydroxide production capacity equipment fixed investments, estimate by economic technology, after the normal operation of band filter, compare with the filter of other production applications, can alleviate labor strength, improve working environment, improve filter quality and production capacity, and 17.1 ten thousand yuan of every production 10000 t aluminium hydroxide Cost reductions.If the fund money rate is to be recoverable fully invested in 10%, 5 year, economic benefit and social benefit highly significant.
