Abstract
The invention relates to a boiler slagging pipe. The boiler slagging pipe comprises an upper slagging pipe, a lower slagging pipe and a slag cooler inlet pipe, wherein the upper slagging pipe is connected with the lower slagging pipe through the slag cooler inlet pipe, a high-temperature gate valve is arranged on the upper part of the upper slagging pipe, a water-cooling nonmetal expansion joint is sleeved on the lower slagging pipe, the output end of the water-cooling nonmetal expansion joint is connected with a connecting pipe, and an accident slagging pipe is vertically arranged on the lower part of the upper slagging pipe. The boiler slagging pipe is capable of adequately ensuring slagging in completely sealed state when the boiler operates, the three-dimensional displacement of the slagging pipe can reach the axle compression of 180-230mm, the radial direction dislocation can reach 50-80mm, reliability and sealing of the device during long time processing can be maximally improved, the characteristics of strong three-dimensional displacement absorption and convenience for later period maintenance are obtained; and a circulating path of the recirculated water does not enter into the slagging pipe, thus a refractory castable is not needed to be laid inside.
Description
Technical field
The invention belongs to boiler slag removal equipment, be specifically related to a kind of boiler slag removal pipe.
Background technology
The CFBB that uses at present, design adopt continuous, surface-cooled mode to carry out deslagging, and every boiler is equipped with cylinder surface formula slag cooler; Through the production practice over one year operation; Scum pipe and slag cooler approach cone body place weld bond cracking and sealing plate repeatedly occur and lead slag pipe distortion, cause that fire, leakage slag phenomenon frequently take place with Louing, and equipment and personnel are caused certain potential safety hazard; A large amount of outwards spray slag phenomenons are increasingly sharpened; Stove zero a rice slag is piled into the mountain, need employ a large amount of labours to clear at every turn, has had a strong impact on economic benefit and site safety normally the carrying out of work of carrying out production strictly in line with rules and regulations.
Summary of the invention
The technical problem that the present invention solved provides a kind of reliability and safe, not stifled slag, the boiler slag removal pipe that temperature tolerance is strong.
For solving above-mentioned technical problem, the technical scheme that the present invention takes:
The boiler slag removal pipe; Its special character is: comprise scum pipe, lower dreg discharging pipe, slag cooler slag feed pipe; Last scum pipe is connected with the lower dreg discharging pipe through the slag cooler slag feed pipe, and the top of last scum pipe is provided with the high temperature push-pull valve, is arranged with the water-cooled non-metal expansion joint on the lower dreg discharging pipe; The port of export of water-cooled non-metal expansion joint is connected with adapter, and the lower vertical of last scum pipe is provided with the accident scum pipe.
Above-mentioned water-cooled non-metal expansion joint is provided with down logical cinder hole.
Above-mentioned last scum pipe is provided with logical cinder hole.
The bottom of above-mentioned adapter is provided with has returned scum pipe.
Compared with prior art, when the present invention can fully guarantee boiler operatiopn, at complete sealing state lower dreg discharging; The three-dimensional displacement energy of scum pipe reaches axial compression 180-230mm; The 50-80mm that radially can misplace can guarantee to improve to greatest extent the reliability and the sealing of equipment long-time running, has three-D displacement and absorbs strong, convenient later maintenance characteristics; Because the circulating pathway of recirculated water does not get into scum pipe inside, so pours need not laid in inside.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is elaborated.
Referring to Fig. 1; The present invention includes scum pipe 1, lower dreg discharging pipe 2, slag cooler slag feed pipe 3; Last scum pipe 1 is connected with lower dreg discharging pipe 2 through slag cooler slag feed pipe 3, and the top of last scum pipe 1 is provided with high temperature push-pull valve 7, is arranged with water-cooled non-metal expansion joint 4 on the lower dreg discharging pipe 2; The port of export of water-cooled non-metal expansion joint 4 is connected with takes over 9, and the lower vertical of last scum pipe 1 is provided with accident scum pipe 5.
Above-mentioned water-cooled non-metal expansion joint 4 is provided with down logical cinder hole 6.
The bottom of above-mentioned adapter 9 is provided with has returned scum pipe 8.
