Abstract
The utility model discloses a waste heat recovering device for high-temperature tail gas of a hot blast stove or a boiler, which comprises a tail gas waste heat recovering water heat exchanger (3), a hot water tank (1) and hot water circulating pumps (2), wherein the tail gas waste heat recovering water heat exchanger (3) is arranged between the outlet of the hot blast stove or the boiler and a dust remover; the tail gas waste heat recovering water heat exchanger (3), the hot water tank (1) and the hot water circulating pumps (2) are connected into a closed cycle through a pipeline; and the hot water tank (1) is connected with a reaction kettle and the boiler through pipelines. The waste heat recovering device adopting the structure has the advantage that heat in the high-temperature tail gas of the hot blast stove or the boiler in the precipitation production of white carbon blacks can be fully used, so that the cost of white carbon black products is lowered.
Description
One, technical field
The utility model relates to a kind of waste heat recovery apparatus, hotblast stove, boiler high temperature using waste heat from tail gas retrieving arrangement during particularly precipitated silica is produced.
Two, background technology
Precipitated silica is a kind of widely used fine chemical product, is mainly used in fields such as rubber, silicon rubber, plastics, coating, printing ink, agricultural chemicals, papermaking, food, medicine, feed.Precipitated silica production master operation comprises building-up reactions, filter press solid-liquid separation, filter cake emulsification, spraying drying, crushing and classification, collection and packing warehouse-in, synthetic precipitin reaction wherein and solid water glass dissolve required steam to be provided by boiler, provide thermal source by hotblast stove for product drying in the production process, and hotblast stove and the boiler exhaust gas temperature is higher and air quantity is bigger, with 8,500,000 kcal/h hotblast stoves and 10t/h boiler is example, the temperature of hotblast stove tail gas is up to 130-150 ℃ in the normal productive process, and air quantity is 60000m
3/ h, the boiler exhaust gas temperature up to 220 ℃ about, air quantity 30000m
3/ h, its heat content that contains is quite high.Generally behind dedusting and thionizer, by smoke stack emission, this part thermal source wastes for existing hotblast stove, boiler high temperature tail gas, and therefore partly thermal source is recycled, and will save a large amount of energy consumptions.
Three, summary of the invention
The purpose of this utility model provides a kind of hotblast stove, residual heat reclaiming apparatus for boiler vent gas, to make full use of the heat energy in hotblast stove, the boiler high temperature tail gas, reduces the white carbon black product cost.
For realizing above purpose, the utility model hotblast stove, residual heat reclaiming apparatus for boiler vent gas comprise using waste heat from tail gas recycle-water interchanger, hot water tank and hot water circulating pump; Using waste heat from tail gas recycle-water interchanger is located between hotblast stove, boiler export and the fly-ash separator, by pipeline using waste heat from tail gas recycle-water interchanger, hot water tank and hot water circulating pump are connected into closed cycle, between hot water tank and reactor, hot water tank and the boiler pipe connection is arranged.
Described hot water circulating pump is two and is and is arranged in parallel.
Adopt said structure hotblast stove, residual heat reclaiming apparatus for boiler vent gas to realize heating of boiler soft stove water and the reaction circulation heating of hot water, improved the temperature of reaction water, shorten heat-up time, can make and enter boiler water temperature and be increased to about 80 ℃ from 20 ℃, increased Boiler Steam and gone out rate, cut down the consumption of energy; Or reactor reaction is increased to about 80 ℃ from 40 ℃ with hot water, and reduced the steam consumption of reactor, shorten reaction end water heat-up time simultaneously, improve throughput, reduce the products production cost.In addition, this precipitated silica reaction vapor heating unit is made simple, and cost is low, and is easy to operate, is beneficial to popularization.
Four, description of drawings
Accompanying drawing is the utility model hotblast stove, boiler high temperature using waste heat from tail gas retrieving arrangement structural representation.
Five, embodiment
Below in conjunction with the drawings and specific embodiments the utility model hotblast stove, residual heat reclaiming apparatus for boiler vent gas are described in further detail.
Shown in the accompanying drawing, the utility model hotblast stove, residual heat reclaiming apparatus for boiler vent gas comprise the hot water circulating pump 2 that using waste heat from tail gas recycle-water interchanger 3, hot water tank 1 and Liang Tai are arranged in parallel; The A of using waste heat from tail gas recycle-water interchanger 3 is to connecing hotblast stove, boiler export, and B is to connecing fly-ash separator; By pipeline, valve using waste heat from tail gas recycle-water interchanger 3, hot water tank 2 and hot water circulating pump 2 are connected into closed cycle; Between hot water tank 1 and reactor, the boiler pipe connection is arranged.
During work, open hot water circulating pump 2, hotblast stove or boiler exhaust gas are from outlet (130-150 ℃ in hotblast stove tail gas, about 220 ℃ of boiler exhaust gas) enters interchanger and recirculated water carries out heat exchange, water through repeatedly closed cycle heating, send reactor or boiler to use after about 80 ℃ the water temperature raising in the hot water tank 1 through 1 of interchanger 3 and hot water tank in the hot water tank 1.
Claims (2)
1. a hotblast stove, boiler high temperature using waste heat from tail gas retrieving arrangement, it is characterized in that: it comprises using waste heat from tail gas recycle-water interchanger (3), hot water tank (1) and hot water circulating pump (2); Using waste heat from tail gas recycle-water interchanger (3) is located between hotblast stove, boiler export and the fly-ash separator, by pipeline using waste heat from tail gas recycle-water interchanger (3), hot water tank (1) and hot water circulating pump (2) are connected into closed cycle, between hot water tank (1) and reactor, hot water tank (1) and the boiler pipe connection is arranged.
