Abstract
The invention discloses an integrated coal economizing and dust collection device, and relates to the field of environmental protection and energy saving. The integrated coal economizing and dust collection device comprises a vertical shell; the shell is arranged on a support; the shell is divided into an upper seal cavity, a middle seal cavity and a lower seal cavity by an upper pore plate and a lower pore plate; the top end of the shell is provided with an outlet end cover; a coal economizer is arranged in the upper seal cavity; coal economizing tubes of the coal economizer are coiled in the upper seal cavity; a plurality of ceramic cyclone tubes are arranged in the middle seal cavity; each ceramic cyclone tube comprises an air inlet cyclone body, a cyclone and a taper ash hole; the air inlet cyclone bodies are connected with the upper pore plate; the taper ash hole in the bottom end of each ceramic cyclone tube is connected with the lower pore plate in a pouring manner; the upper seal cavity and the lower seal cavity are communicated through the ceramic cyclone tubes; the lower seal cavity is a taper hopper; the bottom end of the taper hopper is provided with a blow-down valve; a smoke inlet is formed near the upper end of the middle seal cavity. Ash accumulation is effectively prevented; the occupied area is small; the service life is long.
Description
Technical field
The present invention relates to environmental protection and energy saving field, particularly relate 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 present invention is directed to the deficiencies in the prior art, 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 object of the invention, 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.
Beneficial effect of the present invention: the present invention 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.
