Summary of the invention
The utility model proposes a kind of energy-saving and high efficient desulfation dust-extraction device of UTILIZATION OF VESIDUAL HEAT IN, the waste heat of high-temperature flue gas is utilized, desulfurization and dedusting liquid recycles, and makes whole device operating cost low, the desulfurization dust-removing efficiency height.
The technical solution of the utility model is:
A kind of energy-saving and high efficient desulfation dust-extraction device of UTILIZATION OF VESIDUAL HEAT IN, form by Venturi scrubbing device, desulfurization and dedusting tower, the Venturi scrubbing device is made up of Venturi tube and nozzle, Venturi tube is made up of contraction section, mixer and diffuser, be provided with main heat exchanger and nozzle in the contraction section of described Venturi tube, tube inlet is communicated with clear water reserviors by water pump in the described main heat exchanger, and outlet is communicated with nozzle; Nozzle also is provided with pipeline and is communicated with by the circulating water pool of circulating pump with the desulfurization and dedusting tower.
Be provided with supplementary heat exchanger in the contraction section of described Venturi tube, the inlet of pipe links to each other with water circulating pump in the supplementary heat exchanger, and outlet is communicated with nozzle.
The outlet of pipe is communicated with the afterbody of nozzle in the described main heat exchanger, and the outlet of pipe is communicated with the middle part of nozzle in the described supplementary heat exchanger.
Described nozzle is a steam two-phase nozzle, and nozzle is towards consistent with the flow of flue gas direction.
After being heated into steam with water, the waste heat that device of the present utility model makes full use of flue gas enters nozzle; The desulfurization and dedusting liquid part that the desulfurization and dedusting tower is used recycles, enter nozzle after the waste heat heating of another part by flue gas, the high velocity vapor jet of nozzle ejection provides and has made the power of flue gas by device, and do not need powerful blower fan that energy is provided, the desulfurization and dedusting liquid that steam jet is being carried fully atomizing secretly makes flue gas produce highly turbulent flow, dust in flue gas and SO in Venturi tube
2Being desulfurized dedusting liquid fully absorbs and enters follow-up desulfurization and dedusting tower after the after-purification and carry out further desulfurization and dedusting and demist, when being given full play to, the advantage of Venturi tube overcome the weakness of Venturi tube again, this device efficiency of dust collection can reach 99.5%, the capture particle diameter of dust is 1 micron, and desulfuration efficiency can reach 90%.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As figure, a kind of energy-saving desulfation dust-extraction device of UTILIZATION OF VESIDUAL HEAT IN, comprise Venturi tube and desulfurization and dedusting tower 1, described Venturi tube is made up of contraction section 6, mixer 5, diffuser 4, be provided with main heat exchanger 7, supplementary heat exchanger 8 and nozzle 9 in the contraction section 5, tube inlet is communicated with clear water reserviors 3 by water pump 2 in the main heat exchanger 7, and outlet is communicated with the afterbody of nozzle 9; The inlet of pipe is connected with the circulating water pool 11 of desulfurization and dedusting tower 1 by water circulating pump 10 in the supplementary heat exchanger 8, and outlet is communicated with the middle part of nozzle 9.
