Abstract
The utility model discloses grout heat reclaim unit in a kind of production of precipitated silica, it includes white carbon reaction medial launder, material feeding pump, heat exchanger, chamber-type press filter and connecting pipe, and the import of the material feeding pump connects the outlet of medial launder；The charging aperture connection material feeding pump discharge of the heat exchanger, discharging opening connection chamber-type press filter, water inlet connection running water, delivery port coupled reaction hot water storgae is followed by reactor.Grout heat reclaim unit in above-mentioned precipitated silica production, can not only make full use of heat energy in grout, while also advantageously improving the service life of filter press filter board.
Description
Technical field
The utility model is related to the heat reclaim unit in white carbon black production, and in particular to dilute in precipitated silica production
Slurry heat reclaim unit.
Background technology
Precipitated silica is a kind of widely used fine new material, be mainly used in rubber, silicon rubber, plastics, coating,
The fields such as ink, agricultural chemicals, papermaking, food, medicine, feed.Its production procedure is：Precipitation reaction, aging, press filtration, washing, system
Slurry, spray drying；Precipitation reaction operation need to carry out grout feeding medial launder after terminating it is aging, it is aging after with being pumped to van-type
Filter press carries out separation of solid and liquid.The temperature of grout is higher, up to 80-90 DEG C, if being directly entered filter press carries out separation of solid and liquid not
The service life (filter plate material is RPP) of filter plate can be only reduced, the heat energy in grout can be also wasted.
The content of the invention
The purpose of this utility model is to provide grout heat reclaim unit in a kind of precipitated silica production, abundant
Using the service life for also advantageously improving filter press filter board in grout while heat energy.
To realize object above, grout heat reclaim unit in the production of the utility model precipitated silica, it includes
White carbon reaction medial launder, material feeding pump, heat exchanger, chamber-type press filter and connecting pipe, in the middle of the import connection of the material feeding pump
The outlet of groove；The charging aperture connection material feeding pump discharge of the heat exchanger, discharging opening connection chamber-type press filter, water inlet is connected originally
Water, delivery port coupled reaction hot water storgae is followed by reactor.
Grout heat reclaim unit is made by setting of 316L materials in the precipitated silica production of said structure
Heat exchanger, exchanged heat using running water and grout, the tap water temperature after heat exchange can be improved to 60~65 DEG C, as
Reaction production bottom water is used, due to reacting the raising of bottom coolant-temperature gage, the energy consumption needed for reducing steam heating bottom water, while reducing
The temperature of grout, reduces the influence to filter plate service life.
Benefit measuring and calculating of the present utility model is as follows：
(1) recycling of grout heat will react bottom water and be improved to 60 DEG C from 20 DEG C, be used equivalent to that can reduce steam
Amount 800kg/h, then can reduce steam consumption in year is：
0.8 ton/h × 24h × 300 day=5760 ton steam/year, 5 tons of steam are produced by coal per ton, and coal per ton presses 650 yuan
Meter, then can save coal amount is:
Ten thousand yuan/ton of 5760/5 × 650=74.88, i.e., can reduce and use 74.88 ten thousand yuan of coal expense every year.
(2) grout temperature is down to 50 DEG C from 86 DEG C and enters chamber-type press filter, and the reduction of slurry temperature slow down filter plate (material
Matter is RPP) it is aging, the service life of filter plate is extended.
Brief description of the drawings
Fig. 1 is grout heat reclaim unit structural representation in the production of the utility model precipitated silica.
Reference：Medial launder 1, material feeding pump 2, heat exchanger 3 and chamber-type press filter 4.
Specific embodiment
Grout heat is returned in being produced to the utility model precipitated silica below in conjunction with the drawings and specific embodiments
Receiving apparatus are described in further detail.
Grout heat reclaim unit in the production of the utility model precipitated silica shown in Fig. 1, it includes that white carbon is anti-
Answer medial launder 1, material feeding pump 2, heat exchanger 3, chamber-type press filter 4 and connecting pipe, the import connection medial launder 1 of the material feeding pump 2
Outlet；The charging aperture connection material feeding pump 2 of the heat exchanger 3 is exported, discharging opening connection chamber-type press filter 4, and water inlet connection is certainly
Water, delivery port coupled reaction hot water storgae is followed by reactor.
During work, the grout of medial launder 1 is evacuated to the material feeding of chamber-type press filter 4 with material feeding pump 2 and washs, and centre is by heat exchanger 3
Exchanged heat with water with reaction process, improve reaction bottom coolant-temperature gage reduces the temperature of grout simultaneously.
