Abstract
The utility model discloses a desulfurized gypsum energy-saving dryer, comprising a pre-dirt catcher, a feeding system, a drying pipe and a dirt catcher, which are orderly connected, wherein the feeding system comprises a cylinder, a scraper blade, a spiral feeder, a breaker, an airflow chamber and a motor; the airflow chamber is distributed around the outer wall of the cylinder; the scraper blade, the spiral feeder and the breaker are orderly arranged in the cylinder from the top to the bottom; and the scraper blade is connected with the motor. According to the utility model, the raw gas is used as a heat source to dry the desulfurized gypsum; the airflow of the raw gas is used for conveying gypsum; a draught fan or a booster fan of the gas desulphurization system is used as the power equipment; and the energy-saving dryer has the advantages of low investment, small energy consumption and obvious energy-saving effect.
Description
Technical field
The utility model relates to coal-burned industrial boiler stove and coal-fired plant flue gas desulfur technology, specifically is a kind of desulfurated plaster energy-saving drying device.
Background technology
Product after the desulfurated plaster processing at present all belongs to low value-added product, and the height of dry processing cost has restricted the development of comprehensive utilization prospect of desulfurated plaster.At present general desulfurated plaster drying means needs desulfurated plaster is sent in the equipment such as frying pan, rotary kiln, drying oven, and thermal source generally adopts electric heating, burns coal or power plant's steam, and processing cost is higher relatively.
Summary of the invention
The utility model provides a kind of low, effective desulfurated plaster energy-saving drying device of investing to the problems referred to above.
A kind of desulfurated plaster energy-saving drying device; Comprise the pre-duster, feeding system, dry pipeline and the deduster that connect successively; Described feeding system comprises cylindrical shell, scraper plate, screw feeder, destroyer, airflow chamber and motor; Described airflow chamber is arranged in around the cylinder body outer wall, is provided with scraper plate, screw feeder and destroyer in the described cylindrical shell from top to bottom successively, and described scraper plate, screw feeder link to each other with described motor.Described scraper plate is used to prevent the barrel fouling.
Described pre-duster is selected electric cleaner for use.
As a kind of preferred, be provided with baffle door between described pre-duster and the feeding system, can regulate oven dry back desulfurated plaster moisture content through the baffle door aperture, when not going out gypsum, can baffle door be closed in system.
The deduster that is positioned at behind the dry pipeline is selected sack cleaner for use, is used to collect dried desulfurated plaster.
Apparatus of the present invention are positioned between boiler flue gas outlet and booster fan or the air-introduced machine (if not establishing booster fan).During the device operation, former flue gas gets into dry pipeline through baffle door after electric cleaner carries out preparatory dedusting; Desulfurated plaster through preliminary hydro-extraction falls in the cylindrical shell of feeding system, and barrel rotates to prevent fouling described scraper plate in the drive lower edge of motor, and desulfurated plaster is sent into destroyer by screw feeder; After broken, get in the drying tube road; With former flue gas abundant contact heat-exchanging in dry pipeline, deviate from moisture, simultaneously former flue gas is realized cooling.Get into sack cleaner through dried desulfurated plaster with flue gas and collect the back and get into the dried gypsum warehouse, isolate flue gas behind the gypsum through booster fan or air-introduced machine entering desulphurization system.Simultaneously,, during feeding system work hot flue gas is introduced airflow chamber, carry out predrying desulfurated plaster for carrying out predrying to desulfurated plaster and preventing that moisture the causing in the feeding system when higher of gypsum from boning.
Apparatus of the present invention have the following advantages: adopt former flue gas to carry out the desulfurated plaster oven dry as thermal source, energy-saving effect is remarkable; Use the air-flow of former flue gas own to carry out gypsum and carry, utilize desulphurization system air-introduced machine or booster fan, reduce investment outlay and energy consumption as power-equipment; Desulfurated plaster carries out fragmentation and prebake in feeding system, prevent feeding system and dry pipeline section fouling obstruction.

The specific embodiment
Desulfurated plaster energy-saving drying device as shown in Figure 1 comprises the electric cleaner 1, feeding system 3, dry pipeline 4 and the sack cleaner 5 that connect successively, is provided with baffle door 2 between described electric cleaner 1 and the feeding system 3.As shown in Figure 2; Feeding system 3 comprises cylindrical shell 7, scraper plate 9, screw feeder 10, destroyer 11, airflow chamber 8 and motor 12; Airflow chamber 8 is arranged in around the outer wall of cylindrical shell 7; Cylindrical shell 7 inside are provided with scraper plate 9, screw feeder 10 and destroyer 11 from top to bottom successively, and described scraper plate 9, screw feeder 10 link to each other with described motor 12.
Boiler smoke carries out preparatory dedusting after baffle door 2 gets into dry pipeline 4 through electric cleaner 1; Desulfurated plaster through preliminary hydro-extraction falls in the cylindrical shell of feeding system 3 simultaneously, and barrel rotates to prevent fouling described scraper plate 9 in the drive lower edge of motor 12, and desulfurated plaster is sent into destroyer 11 by screw feeder 10; After broken, get in the drying tube road 4; With former flue gas abundant contact heat-exchanging in dry pipeline 4, deviate from moisture, simultaneously former flue gas is realized cooling.Get into sack cleaner 5 through dried desulfurated plaster with flue gas and collect the back and get into the dried gypsum warehouse, isolate flue gas behind the gypsum through booster fan 6 or air-introduced machine entering desulphurization system.Simultaneously,, during feeding system work hot flue gas is introduced airflow chamber 8, carry out predrying desulfurated plaster for carrying out predrying to desulfurated plaster and preventing that moisture the causing in the feeding system when higher of gypsum from boning.
Application examples: flue-gas temperature is 136 ℃, and dry pipeline baffle door aperture is 90%, gets into dry piping flow and is 600000Nm
3/ h, desulphurization system gypsum output is about 10t/h, and the desulfurated plaster moisture content of undried is 12.5%, and gypsum purity is 93%.Shown in accompanying drawing, (dust content is about 200mg/Nm to flue gas after the preparatory dedusting of electric precipitation
3) get in the dry pipeline.Desulfurated plaster gets into dry pipeline by charging aperture with flue gas behind feeding system; The flue gas that has dried gypsum gets into sack cleaner subsequently; Dry desulfurated plaster gets into warehouse after sack cleaner is collected, flue gas then gets into desulphurization system through air-introduced machine or booster fan.Through dried desulfurated plaster moisture content is 4.1%, and purity is 92%.
