Abstract
A wet combined high efficiency desulfurizing and dust-removing device which comprises a casing, a gas inlet, an impact chamber, a centrifugal separation chamber, a dehydration chamber with a compound plate, a gas outlet and a balance water tank, is characterized in that the gas inlet is provided with a spray thrower, and a Venture channel is arranged under the spray thrower, and an outlet of the Venture channel is communicated with the impact chamber. The utility model has the advantages that the utility model has double functions with an integration of the desulfurization and the dust-removal; the utility model has perfect desulfurizing and purifying effects which a discharge concentration of gases in a general gratefiring coal fired boiler is less than 100 mg/nm<3> and reaches the first grade area standard, and a dust removal efficiency is not less than 96 percent and a desulfurizing efficiency is between 60 percent and 80 percent, and a discharge concentration of sulfur dioxide is lower than the national discharge standard; the utility model has a perfect corrosion proof capability, a high reliability, a low cost and a long service life; the utility model is easy to operate and maintained, and don not need a full time operator.
Description
Technical field
The utility model belongs to a kind of dust-removing device for boiler, particularly a kind of wet type assembled highly-effective desulfurizing dust-collector.
Background technology
The applicant had once developed SJ-double click type desulfurizing dust-collector in 1994, and was used for the boiler dusting of enterprise, through use practice in a few years, discovery remains in certain deficiency, efficient as sulphur removal is lower, and the effect of dedusting is desirable not enough, awaits further to improve.
The utility model content
The purpose of this utility model provides a kind of wet type assembled highly-effective desulfurizing dust-collector, desulphurizing and dust-removing integral, and desulfurization and dedusting is effective, and corrosion resistance and good improves service life, and is reliable, expense is low.
The purpose of this utility model is achieved by the following technical solution: it includes dewatering station, exhanst gas outlet and the balanced reservoir etc. of housing, smoke inlet, impulse chamber, centrifugation chamber, band compound plate, it is characterized in that: spray thrower is set in smoke inlet, Wen's passage is set below spray thrower, and Wen's channel outlet is communicated with impulse chamber.
The utility model has the advantages that: desulphurizing and dust-removing integral has dual-use function; The dust-removal and desulfurizing good purification, the smoke dust discharge concentration of general grate-firing coal burning boiler is no more than 100mg/nm
3, can satisfy a class regional standard, efficiency of dust collection is greater than 96%, desulfuration efficiency 60-80%, sulfur dioxide emissioning concentration is lower than national specified discharge standard; Corrosion resistance and good improves service life; Simple to operate, can not establish full-time operating personnel, easy to maintenance, reliable, expense is low.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
See Fig. 1, concrete structure is as follows: the housing 2 of steel is provided with smoke inlet 3 and exhanst gas outlet 1, spray thrower 5 is set in smoke inlet 3, spray thrower 5 spray alkaline aqueous solutions, its objective is alkaline aqueous solution is sprayed in flue gas with the water smoke shape, help sulfur in smoke and absorbed, and regulate the pH value of liquid, so that better remove sulfur dioxide in the self-excitation stage afterwards by alkali lye.Simultaneously, the spray of alkaline aqueous solution can make flue-gas temperature descend, and quickens the reaction of alkali lye and sulfur dioxide, is beneficial to the absorption to sulfur dioxide.And the water smoke that sprays plays the effect that humidification increases weight to dust in flue gas, and granule coalescence bulky grain is for the back inertia impact creates conditions.Wen's passage 6 is set below spray thrower 5, and 6 outlets of Wen's passage are communicated with impulse chamber 7.Because it is narrow that Wen's passage 6 shrinks, flue gas flow rate is accelerated, and has created necessary condition for next step impacts to the water surface, and by slype the time, help fully contacting of sulfur dioxide and alkaline aqueous solution, and collision mutually between the flue dust, the probability of coalescence increases mutually.Impulse chamber 7 is communicated with the circuitous of self-excitation chamber 8 and centrifugation chamber 12 formations
Passage, flue gas are by impulse chamber 7, and most of soot dust granule enters in the water, and flue dust obtains further isolation of purified during by self-excitation chamber 8 and centrifugation chamber 12.The top of centrifugation chamber 12 outlet is provided with dewatering station 13, and dewatering station 13 is provided with the compound plate 14 that multilayer interlaces, flue gas during by dewatering station bump multilayer compound plate 14 further purified, before exhanst gas outlet 1, formed the flue gas of cleaning.In order to improve resistance to corrosion, at the inner surface application acidproof heat-proof high-abrasive material of gas, liquid contact.The balanced reservoir 11 that adds water in a side setting of housing.Bottommost assembling ash discharge butterfly valve 9 at housing.Housing is supported by equipment supporter 10.
Claims (2)
1, a kind of wet type assembled highly-effective desulfurizing dust-collector, it includes dewatering station, exhanst gas outlet and the balanced reservoir etc. of housing, smoke inlet, impulse chamber, centrifugation chamber, band compound plate, it is characterized in that: spray thrower is set in smoke inlet, Wen's passage is set below spray thrower, and Wen's channel outlet is communicated with impulse chamber.
2, wet type assembled highly-effective desulfurizing dust-collector according to claim 1 is characterized in that: at the inner surface application acidproof heat-proof high-abrasive material of gas, liquid contact.
