Abstract

The utility model relates to a dust collecting and heat saving device which is formed by utilizing multi-tube cyclone dust collectors, wherein, the goal of dust collecting on high temperature dust waste gases can be achieved by the cyclone dust collectors. Independent space is formed between an inlet pipe fixed plate arranged above a plurality of single distributed cyclone collectors and a sealing fixed plate arranged under the cyclone dust collectors. The distributed plurality of single cyclone dust collectors are divided into a Z-shaped air flow passage through partition boards in the independent space in which a heat exchanger is arranged. Both ends of the Z-shaped air flow passage are of a room temperature air inlet and a room temperature air outlet. The outside air flows through the Z-shaped air flow passage and does the heat exchange with a cylinder cone body of each single cyclone dust collector with the high temperature waste gases.

Description

Multi-cyclone control of dust and economizer

The utility model is the device of a kind of control of dust and Jie Re.The control of dust and the economizer that particularly utilize the particular arrangement of multi-tube dust collector to carry out recuperation of heat.

Multi-tube dust collector is a kind of of existing dry type cyclone, is dust-contained airflow is entered in the cylinder cone via top vortex guide vane, the centrifugal force that utilizes its high speed rotary to produce, and reach the control of dust purpose.The cyclone that quantity is a lot, arrange and (square or rectangular is arranged) is set in the casing of same import and export, dust-contained airflow is evenly distributed in each cylinder cone allows unordered air-flow and crushing be reduced to minimum, the then separated funnel bottom that is deposited in of dust.Can be according to the processing air quantity, the droop loss size, dust catching efficiency, how many particle size selects caliber size and quantity.

Aspect energy technology utilizes, utilize heat recovery system from the exhaust device of gas turbine, diesel motor, boiler, kiln, incinerator and other discharging heat, to reclaim heat cost-effectively.In the application of recuperation of heat, the type of heat exchanger has: air is to gas, gas to water, gas to organic fluid, gas to water or steam etc., and air to gas application on, air preheater is to be used for reclaiming the contained heat energy of chimney exhaust gas, and improve a kind of heat-exchange apparatus of combustion-supporting chamber's temperature, have and can significantly reduce fuel consumption and improve the boiler combustion efficiency double benefit.

Therefore, the Waste Heat Recovery of air preheater is used, and is commonly industrial quarters and adopts, yet when any type of air preheat interchanger use Waste Heat Recovery, all may face the dust obstruction, the problem of crushing increase or cold end corrosion.Avoid extended surface tube to be had by the method that dust stops up: install soot blower (Soot Blower), filter screen (Filter) additional, adopt box (Cassette) the heat pipe heat exchanger, add wet method (Wet Air) and vibration dust method (Vibration) etc., wherein first three methods is fit to a spot of dust of control and stops up.The heat exchanger of box, the heat pipe of each row of tool can independently be extracted out and change or clean, but cost is higher.Add wet method and be fit to adopt when the moisture deal of waste gas is the highest, before waste gas enters heat pipe exchanger, hot water or steam are sprayed among the waste gas, make it, condense to quicken its dew point on tube wall near saturation state.

Adhere to solids and have the effectiveness that reduces pollution on the device of only a few, recuperation of heat program itself does not reduce air or water pollutes.Dust stops up incrustation to the utility model in the heat exchanger in order to overcome, and alleviates its wearing and tearing, improves heat recovery efficiency, can solve air pollution problems inherent (shot-like particle, cold end corrosion) simultaneously; With multi-tube dust collector modification the becoming air preheat interchanger of an air, will solve air pollution problems inherent from the waste gas control of dust of chimney or waste heat source on the one hand to gas; On the one hand will single cyclone be used as heat pipe and transmit heat by heat pipe and make and enter the air preheat that boiler combustion uses and reduce the heat of waste gas mistake that body is arranged, thereby can reduce the fuel consumption of boiler, the efficiency of combustion of raising boiler.

Known dust arrester, as No. the 200021st, Taiwan patent announcement, name is called " tower cyclone ", or announce No. 165597 " the special-purpose dust arrester of chimney " though etc. all have the function of control of dust, can't reclaim used heat effectively simultaneously.

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of have concurrently control of dust and joint hot merit can multi-cyclone control of dust and economizer, this device can prevent that air pollution again can energy savings, and improves efficiency of combustion.

The purpose of this utility model is achieved in that

A kind of multi-cyclone control of dust and economizer, it is to utilize the multi-tube dust collector configuration to form, several single cyclone of arranging are fixed with the inlet tube fixed head, become a separate space between the sealing fixed head of inlet tube fixed head and below, place as heat exchanger, this separate space and with dividing plate perpendicular to the sealing fixed head of top inlet tube fixed head and below, link these both, and several single the cyclone that will arrange are separated into the zigzag air flow channel, one end of this zigzag air flow channel is the air intake of a normal temperature, the other end then is the air outlet slit of high temperature, suck and send for outside air, outside air this zigzag air flow channel of flowing through, and carry out heat exchange with the cylinder cone of each single the cyclone that contains high-temp waste gas.

Multi-tube dust collector can be the multi-tube dust collector of wing shaft type multi-tube dust collector or other patterns; Also add an air-introduced machine that motor is housed up near the outlet.

The utility model utilizes a plurality of cyclones to constitute a heat exchanger, makes it to have control of dust and recuperation of heat double effects, can prevent that air pollution again can energy savings.This device can be arranged between waste heat source and the general heat exchanger, improves rate of heat exchange on the one hand, reduces the flue outlet temperature.Avoid general heat exchanger cigarette ash to stop up on the one hand, the air pollution that selective sootblowing caused also has the effect that prolongs life of heat-exchanger.

The utility model as air preheater, has increased the contact area of heat exchange because a plurality of single the dust arresters that will arrange are separated into the air flow channel of zigzag, improves rate of heat exchange, and reduces the high-temperature exhaust air amount, reduces contamination preventing equipment and running cost.The intake air that improves temperature via heat exchange can also be made for the heating source of other purposes.

The utility model is that a kind of combination is simple, can make the control of dust and the economizer of different configurations according to different environmental condition permissions, utilize intrinsic pressure fan of combustion apparatus and chimney that running can be installed, need not increase auxiliary power in addition, but also can additionally install air-introduced machine again additional to improve the efficient of ventilating.
