Description
Technical field
The utility model relates to environmental protection and energy saving field, particularly relates to a kind of energy-saving duster.
Background technology
Economizer, is the heating surface of saturation water boiler feedwater be heated in boiler back end ductwork under drum pressure, due to the heat of the low-temperature flue gas that its absorbs, reduces the exhaust gas temperature of flue gas, save the energy, improve efficiency.Economizer is made up of horizontally disposed connector bend in parallel (practise and claim coiled pipe).
boiler economizerbe installed on a kind of device of boiler tail for recovery waste heat.Mainly be applicable to industry, also spread to agricultural in recent years and some related industries are commercial.
But because in flue gas, impurity is more, directly being contacted with the coal saving tube of economizer by flue gas easily makes the impurity such as flue dust at coal saving tube surface condensation laying dust, time has been grown and has caused endothermic effect lower, need keep in repair, cause shorten service life, prior art generally need add dust arrester to reach the problem preventing impurity laying dust before economizer, but floor space is larger, and complex structure, is further improved.
Summary of the invention
The utility model is for the deficiencies in the prior art, and provide one and effectively prevent dust laying dust, floor space is little, and the integral type of long service life economizes coal dust arrester.
For realizing the utility model object, provide following technical scheme: integral type economizes coal dust arrester, it is characterized in that comprising upright shell, housing is placed on support, housing is divided into upper, middle and lower three sealed chamber by upper orifice plate, top is provided with outlet end cap, economizer is provided with in upper chamber, the coal saving tube dish of economizer is distributed in upper chamber, several ceramic rotary airducts are provided with in middle chamber, ceramic rotary airduct comprises and connects air intake cyclone body in turn, cyclone cylinder, taper ash hole, described air intake cyclone body is poured into a mould with up-hole plate and is connected, bottom taper goes out back grey mouth and pours into a mould with orifice plate and be connected, upper and lower chamber is made by ceramic rotary airduct, described lower chambers is taper bucket, taper bucket bottom is provided with blowoff valve, gas approach is arranged at the nearly upper end of middle chamber.
As preferably, described ceramic rotary airduct is that high temperature ceramic material is formed.
As preferably, coal saving tube is stretched in ceramic rotary airduct.
As preferably, periphery, coal saving tube is inlaid with heat transmission fin.
As preferably, the whirl directing vane that described air intake cyclone body comprises central row tracheae and is arranged between cyclone cylinder inwall and central row tracheae, described central row tracheae upper end lower than or flush cyclone cylinder upper end, central row tracheae upper end offers ladder shelves, wireway lower end is set to the ladder shelves connected with central row tracheae upper end, and described wireway lower end is inserted central row tracheae upper end and is tightly connected.
The utility model beneficial effect: the utility model passes through integrated setting, by vertical arrangement, flue gas enters from middle chamber and is sucked by ceramic rotary airduct, dust is from lower discharge, flue gas after impurity screening is upwards entered upper chamber and is absorbed heat by economizer, effectively prevent the condensation of coal saving tube dust, extension device service life, and effectively reduce floor space.
