Abstract
The invention discloses a cleaning device for a heat exchange tube of a waste heat boiler. The cleaning device comprises two clamping arms, metal steel wire cleaning balls and steel wire ball state keeping parts, wherein two ends of the steel wire ball state keeping parts are placed against the metal steel wire cleaning balls; the length of the steel wire ball state keeping parts is corresponding to the diameter of a heat exchange tube to be cleaned; the metal steel wire cleaning balls with the steel wire ball state keeping parts are equidistantly arranged between the two clamping arms; the two clamping arms fixedly clamp the steel wire ball state keeping parts and the metal steel wire cleaning balls; the steel wire ball state keeping parts are vertical to the clamping arms; and the distance between two adjacent steel wire ball state keeping parts is corresponding to the diameter of the heat exchange tube to be cleaned. Since the steel wire ball state keeping parts are placed against the metal steel wire cleaning balls, the metal steel wire cleaning balls can be kept at a fixed shape for a long time to overcome the flexibility and gravity effect of the metal steel wire cleaning balls, thereby prolonging the service life of the cleaning device for the heat exchange tube of the waste heat boiler.
Description
Technical field
The present invention relates to the servicing unit technical field of the preboiler utilizing preheating, particularly a kind of exchanging pipe of boiler by waste clearing apparatus.
Background technology
At present, a large amount of energy resource consumptions is needed in various field of industrial production, by various thermal power transfer equipment in production process, produce and unemployed heat energy with in energy equipment and chemical reaction equipment, and a large amount of various forms of waste heats can be produced in process of production, the source of waste heat mainly contains industrial exhaust gas waste heat, the waste heat of high-temperature product and slag, the waste heat of cooling medium, what generate in chemical reaction process abandons heat, combustible exhaust gas, waste material, the heat energy of waste liquid and waste vapour, the waste heat of waste water, and the evenly heat efficiency of Industrial Boiler only has 67 ﹪, remaining energy passes through the useless fume emission of high temperature in the middle of air, cause great waste.
The UTILIZATION OF VESIDUAL HEAT IN of Boiler Manufacturing Industry be energy-conservation at present in an important topic, it has very high economic benefit and social benefit.Such as, the smelting furnace UTILIZATION OF VESIDUAL HEAT IN in Boiler Manufacturing Industry, is converted to other energy by the used heat of being discharged by smelting furnace, as electric energy, steam-energy or directly go to drive other plant equipment and heat supply as power.But at present in smelting furnace UTILIZATION OF VESIDUAL HEAT IN, the subject matter of encountering is that residual heat boiler for exchanging heat surface ash-clearing technology is efficient not, reliable, its main cause is that the waste gas of smelting furnace contains the superfine dust of a large amount of particles, there is stronger adsorptivity, greatly heat exchange efficiency is affected after being bonded at the heat exchange surface of waste heat boiler, further, because operating environment temperature is at 500 DEG C ~ 600 DEG C, make traditional waste heat boiler ash-clearing technology, such as steam blowing, compressed air purging, rapping, shock wave and sound wave cleaning etc. are all difficult to clean clean set of heat exchange tubes surface.
Carrying out the more effective mode of deashing operation to the heat exchange surface of waste heat boiler is as under type: between heat exchanger tube, be provided with dust cleaning brush, makes dust cleaning brush move up and down on heat exchanger tube surface to realize contact cleaning.
But moving up and down in process as the steel wire lump of one of dust cleaning brush critical piece; due to self flexibility and Action of Gravity Field; and simultaneously at high temperature long-play; cause cannot returning to original shape or down drooping; thus brush less than heat exchange tube wall; cause deashing only not go out the thermal efficiency in order to what ensure whole waste heat boiler, need often to change whole dust cleaning brush, so can increase cost affects whole waste heat boiler group simultaneously operating efficiency owing to needing to shut down.
Summary of the invention
In view of this, the exchanging pipe of boiler by waste clearing apparatus providing a kind of service life longer is necessary.
A kind of exchanging pipe of boiler by waste clearing apparatus, comprises two clamping limbs, metal steel wire cleaning ball, steel wire lump state keeper.Two ends and the metal steel wire cleaning ball of steel wire lump state keeper abut against, the length of steel wire lump state keeper is corresponding with the diameter of heat exchanger tube to be cleaned, be provided with that the metal steel wire cleaning ball of steel wire lump state keeper is equally spaced to be arranged between two clamping limbs, steel wire lump state keeper and metal steel wire cleaning ball are fixedly clamped by two clamping limbs, and steel wire lump state keeper is vertical with clamping limb, the distance between two adjacent steel wire lump state keepers is corresponding with the diameter of heat exchanger tube to be cleaned.
When utilizing above-mentioned exchanging pipe of boiler by waste clearing apparatus to clean heat exchanger tube, because steel wire lump state keeper and metal steel wire cleaning ball abut against, make metal steel wire cleaning ball can keep fixing shape for a long time, to overcome flexibility because of metal steel wire cleaning ball self and Action of Gravity Field, so extend the service life of exchanging pipe of boiler by waste clearing apparatus, without the need to frequent replacing, then reduce costs, keep the operating efficiency of whole waste heat boiler group.
