The invention discloses an integrated low-carbon micro-discharge energy-saving and emission-reduction boiler system. The system comprises a boiler body (1), a steam drum (2), a heat exchanger (3), a preheater (4), an economizer (5), a superheater (6), a steam turbine (7), a generator (8), a secondary smoke combustion device (9), a desulfuration and dust collect unit (10), an air blower (11) and a smoke exhauster (13), wherein the steam drum (2) and the heat exchanger (3) constitute a hot-water heating circulation loop, the economizer (5) is connected with the steam drum (2), and the air blower (11) feeds air to the preheater (4); the steam drum (2) is connected with the superheater (6), and then connected with the steam turbine (7) by a superheated steam pipe (22); the steam turbine (7) is connected with a low-pressure steam pipe (23), and the generator (8) is linked with the steam turbine (7); and the outlet of a gas duct of the boiler body (1) is connected with a smoke pipe (25), and the smoke exhauster (13) is arranged on the smoke pipe (25), and sequentially feeds smoke into the secondary smoke combustion device (9) and the desulfuration and dust collect unit (10) so as to process and discharge the smoke.

The invention relates to an oxygen-enriched sintering flue gas circulation system and application. The oxygen-enriched sintering flue gas circulation system involves a sintering machine, a first dustremover, a first fan, an oxygen adding system, a second dust remover, a second fan and a post-treatment unit; the oxygen adding system enables oxygen to be uniformly mixed with circulation flue gas, so that the stability of the sintering yield and the quality is ensured; and a detection unit detects the content of the oxygen in the circulation flue gas in real time, the adding amount of the oxygenis adjusted through a control unit, the content of the oxygen in the mixed flue gas is detected in real time, and the control unit adjusts a flow adjusting device according to the feedback to enablethe content of the oxygen in the circulation flue gas to be 18%-30%. According to the oxygen-enriched sintering flue gas circulation system, the oxygen adding system is simple in structure, the oxygenflow can be accurately and quickly adjusted, the defect that the circulation flue gas flow is reduced due to additionally-added annular cold waste gas or air is avoided, the flue gas circulation ratecan be increased to 60% at the highest, and the flue gas emission reduction effect is improved.

The invention discloses an environment-friendly backfire clean coking and gas making and electricity generating polygeneration device. The whole set of device comprises a coking and gas making furnace body, a heat exchanger, a separator, a booster fan and the like. An automatic control system is equipped to realize full-automatic intelligent operation. The device can adapt to coking, gas making and electricity generating of vast majority of coal, also can prepare biomass charcoal from biomass, such as wood, bamboo, stalks, rice hulls, garbage bars and the like, and generates clean fuel gas to generate electricity while preparing the charcoal so as to realize polygeneration. When the device performs pressure operation, the rate of coking and making charcoal can be controlled by adjusting the pressure (even negative pressure). The device also can completely prepare fuel gas for generating electricity when the charcoal is not needed to be made. The device can meet various requirements of different users in different places, and ensures that sewage is not discharged in the whole process of coking (making charcoal) and generating gas and electricity on the structure. Zero emission is achieved except the noise and tail gas of a generator.

The invention relates to a whole-process circular dyeing method of a real silk fabric and a dyeing system, and belongs to the technical field of printing and dyeing. The method comprises the followingsteps that (1) a reactive dye is used for dyeing, meanwhile, residual dyeing liquid is separated by a dyeing wastewater pool and a first dye separator to obtain colorless clear water, and the colorless clear water is stored in a dyeing clear water pool and is circularly used for a dyeing section; (2) wastewater in a soaping section is separated by a soaping wastewater pool and a second dye separator to obtain colorless clear water, and the colorless clear water is stored in a soaping clear water pool and is circularly used for the soaping section and the dyeing section or is discharged; and (3) wastewater in a water washing section is separated by a water washing wastewater pool and the second dye separator to obtain colorless clear water, and the colorless clear water is stored in a water washing clear water pool and is circularly used for the water washing section, the soaping section and the dyeing section or is discharged; and (4) wastewater in a color fixing section is directly circularly used for the color fixing section or is discharged after being temporarily stored in a color fixing wastewater and clear water pool.
