Description

Waste Heat Recovery dedusting takes off haze device

Technical field

The utility model relates to a kind of high efficient heat exchanging of flue gas waste heat recovery at station boiler, chemical industry heating furnace, biomass boiler and Industrial Stoves and the device of dedusting, and the Waste Heat Recovery dedusting carrying out work under especially relating to the process conditions that a kind of dust content at biomass boiler is large, water content is large takes off haze device.

Background technology

Along with the development of society, the dependence of the mankind to non-renewable energy resources is more and more higher, and the pollution of environment is also day by day serious.In order to alleviate the pressure of environment and social development, biomass boiler is more and more subject to the favor of some enterprises, and it not only solves the impact of non-renewable energy resources crisis, also alleviates the pressure of environment.The fuel source of biomass boiler is the crops utilizing all wastes such as stalk, paddy rice stalk, yule logs, wood chip, peanut shell, melon seed cases, beet pulp, bark, through being pulverized and mixed the techniques such as extruding oven dry, finally make granular fuel, the enterprise even had changes into imflammable gas more further granular fuel and burns.This fuel not only wide material sources, clean, can solve again the problem of pollution remission.In order to cost of reducing investment outlay, some enterprises often have employed conventional structure at the heat-transfer surface of boiler tail, and due to site condition restriction or designer's experience problem, the heat-transfer surface of this ordinary construction is owing to can not get rational design ap-plication, heat exchange efficiency is low and cause bulky, and consumable quantity is large.Containing a large amount of flue dust in the flue gas of biomass boiler, and cause because the moisture in fuel is too high in flue gas containing a large amount of water vapours, wearing and tearing, stifled ash is caused to the common heat-transfer surface of boiler tail, heat exchanger tube is worn and torn leak out, or air-introduced machine is exerted oneself not smooth, cause exhaust gas temperature void low further, form vicious circle and cause afterbody heat-transfer surface to lose efficacy.

In order to avoid the appearance of this situation, boiler is had to regular blowing out, opens afterbody heat-transfer surface and carries out deashing, or maintenance, changes.This regular maintenance not only causes the direct losses sharply increased of enterprise's maintenance cost, and causes huge indirect loss because enterprise stops production.Therefore one can realize high efficient heat exchanging simultaneously, and the equipment that effectively can solve again the large problem of stifled ash, wearing and tearing and ash disposal three is extremely urgent.

Utility model content

The purpose of this utility model overcomes the problems such as efficient, stifled ash of the prior art, wearing and tearing and deashing, and provide a kind of Waste Heat Recovery dedusting to take off haze device.

The utility model is achieved through the following technical solutions: Waste Heat Recovery dedusting takes off haze device, be installed vertically on the back-end ductwork of boiler, comprise SP heat exchanger tube, upper perforated plate, lower perforated plate, inner barrel, spiral plate and outer cylinder body, SP heat exchanger tube is built in inner barrel, the upper end of SP heat exchanger tube is connected with upper perforated plate, and lower end is connected with lower perforated plate; The upper end of inner barrel is connected with the cylindrical of upper perforated plate, is connected after lower end is connected with expansion joint with the cylindrical of lower perforated plate again, and expansion joint is between SP heat exchanger tube and inner barrel; The epimere of inner barrel is provided with the gas approach mouth of pipe, and the gas approach mouth of pipe extends to outside outer cylinder body, and the hypomere of inner barrel is provided with the inner barrel exhanst gas outlet mouth of pipe be placed in outer cylinder body; Lower perforated plate is connected with lower tube box, and lower tube box is provided with the air intlet mouth of pipe extended to outside outer cylinder body, and upper perforated plate is connected with upper tube box, and upper tube box is provided with the air outlet slit mouth of pipe; Described upper perforated plate, lower perforated plate, SP heat exchanger tube and inner barrel composition heat exchange unit; Spiral plate spirals and is arranged on the outer wall of inner barrel, and the upper end of inner barrel and the upper end of outer cylinder body are linked together by shrouding and deep floor, and the epimere of outer cylinder body is provided with the outer cylinder body exhanst gas outlet mouth of pipe, and its lower end is connected with the ash bucket of band ash disposal mouth; The de-haze unit of described inner barrel, spiral plate, ash bucket, outer cylinder body composition.

Adopt expansion joint between SP heat exchanger tube and inner barrel, high-temperature expansion difference problem between the two can be solved; Linked together by shrouding and deep floor between inner barrel and outer cylinder body, high-temperature expansion difference problem between the two can be solved; Flue gas passes in inner barrel from top to bottom, and enter the passage between inner barrel and outer cylinder body by the inner barrel exhanst gas outlet mouth of pipe, finally flow out from the outer cylinder body exhanst gas outlet mouth of pipe on outer cylinder body top, air then from below to up by SP heat exchanger tube to upwards, and outside from air outlet slit mouth of pipe bleeder.This device heat exchange unit forms the three-dimensional arrangement becoming space with disengaging unit, and the special shape that three-dimensional change space refers to due to heat exchanger tube makes the runner outside pipe be horizontal multichannel, longitudinal total space, the outer three dimensions of pipe forming different cross section constantly changes, fluid flowing is without dead angle, the three-dimensional layout becoming space can make device that traditional collision stream is become frictional flow, optimize the flow field of fume side, make flow field more rationally evenly, while realizing full countercurrent flow, the wearing and tearing of flue gas to SP heat exchanger tube can be solved again, reduce drag losses.Under same drag losses, greatly can improve rate of flow of fluid, further increase again the heat exchange efficiency of heat exchanger tube from process means.Spiral plate spirals and is arranged on the outer wall of inner barrel, flue gas can be flowed along its direction, utilize the principle of centrifugal force, often rotate a circle and just heavy soot dust granule is thrown to the internal face of outer cylinder body, the soot dust granule being subject to Action of Gravity Field is concentrated along the wall of outer cylinder body or spiral plate and is dropped at ash bucket, then goes out through dust removal port.The setting of de-haze unit, makes flue gas create violent turbulent flow, destroys the boundary layer flow thickness of flue gas near wall, improve the heat exchange efficiency of heat exchanger tube, decrease the possibility of heat exchanger tube surface scale simultaneously from heat transfer mechanism.
