Abstract
A filter used for separating sodium bicarbonate from mother liquid in the production of sodium carbonate is a rubber-belt vacuum filter with material inlet, sprinkling unit above rubber belt and a filtering cloth-water washing unit under rubber belt.
Description
Technical field
The present invention relates to a kind of production technology of soda ash, sodium acid carbonate and mother liquor filter for separating during particularly soda ash is produced.
Background technology
In ammonia-soda process and connection alkaline process production technology, the sodium acid carbonate crystallization that generates after the carbonating is sent in the steam roaster and obtains soda ash after the calcining with after mother liquor separates.Filtration and washing at heavy alkali are the important process processes of heavy buck part of control and salt content, directly influence the quality of soda ash and the normal operation and the output of calcining furnace, and the mother liquor balance and the production cost of system had decisive role.
At present, employed filtration of bicarbonate equipment is vacuum-type drum filter in soda ash production, and there is following shortcoming in it, and the vacuum consumption is big, the washing water yield is big and can not reclaim repeated use, and filter cake moisture content height is generally 18%, power consumption is high, and washings enter in the mother liquor, and system balancing is wayward.A kind of rubber belt type vacuum filter is used in metallurgy, mine, papermaking and food service industry already, this filter is to be produced by Huadong Yantai Machinery Plant, Ministry of Nuclear Industry, it does not need the pressure blowing device, and is energy-conservation, the filter efficiency height, washings do not mix mutually with mother liquor, reusable, plant maintenance is easy, can overcome the shortcoming of rotary drum vacuum filter, yet this belt vacuum filter is not applied in the system alkali industry as yet.
Summary of the invention
The technical issues that need to address of the present invention provide sodium acid carbonate and mother liquor filter for separating in a kind of soda ash production, and its energy consumption is low, and filter cake moisture content is low, and the washings consumption is little and can reclaim repeated use.Technical scheme of the present invention is, sodium acid carbonate and mother liquor filter for separating during soda ash is produced, it is characterized in that: used filter is a rubber belt type vacuum filter, top, rubber strip one termination is provided with charging aperture, above the rubber strip between charging aperture and the discharge end, be provided with spray equipment, below the rubber strip lower surface, be provided with the filter cloth washing equipment.The present invention is owing to make heavy alkali with rubber belt type vacuum filter and separate with mother liquor, thus with existing vacuum-type drum filter relatively have energy-conservation, low and the little and reusable remarkable advantage of washings consumption of filter cake moisture content.
Description of drawings
Accompanying drawing is the structural representation of rubber belt type vacuum filter.
The specific embodiment
In conjunction with above accompanying drawing the present invention is described in detail, rubber belt type vacuum filter, make by nuclear industry Yantai machinery plant, and at metallurgy, the mine, use for many years in papermaking and the food service industry, it is applied in the alkali-making industry, should charging aperture be set in conjunction with the specified conditions of system alkali, the spray washing auxiliary equipment, annulus rubber cincture 1 is done continuous motion by driving mechanism, filter cloth 2 is laid on the surface of rubber strip and is synchronized with the movement with rubber strip, the charging aperture 3 of heavy alkali slip is set above the rubber strip left end, above between rubber strip charging and the discharge end 5, elution device 4 is set, below the lower surface of rubber strip, be provided with filter cloth washing equipment 6 and rubber strip washing equipment 7, guarantee the permeability of rubber strip and filter cloth micropore.This belt vacuum filter utilized the gravity discharging voluntarily of material, saved device and energy consumption with high pressure wind material, and the filter cake that is filtered is moisture low, the efficient height, because this filter is except that vacuum tank 8, rubber strip and filter cloth are open type, and be easy to maintenance.
