Abstract
The invention relates to a temperature-adjusting baffle for a boiler flue. The temperature-adjusting baffle comprises a front baffle and a rear baffle, wherein the front baffle is arranged in a front flue, the rear baffle is arranged in a rear flue, the front baffle and the rear baffle are respectively arranged in parallel to a left wall and a right wall, the front baffle and the rear baffle are coaxially coupled, the positions of the front baffle and the rear baffle are mutually vertical and fixed, and operations of the front baffle and the rear baffle can be controlled by a couple axle from a front wall or a rear wall. The temperature-adjusting baffle for the boiler flue provided by the invention has the advantages of simple for coupling, convenient for manufacture and installation, flexible for adjustment, better adaptability and good temperature-adjusting effect.
Description
Technical field
The present invention relates to a kind of boiler flue temperature adjustment baffle plate.
Background technology
Boiler technology constantly develops at present, and the capacity of domestic station boiler constantly enlarges, and in boiler operatiopn, is different from superheater system, and for the adjusting of reheater steam temperature, the method for most of now employing back-end ductwork temperature adjustment baffle plate is regulated.
Because present boiler (coal-powder boiler and recirculating fluidized bed CFB) the continuous cause of increased of capacity; The cross section of boiler back end ductwork also constantly increases, and more and more wideer, the smoke distribution non-uniform phenomenon is serious all the more; In actual moving process, we find that reheater local overheating phenomenon happens occasionally; In addition, present temperature adjustment shutter configuration is the temperature control panel that laterally arranges with front-back wall, because the flue width between the front-back wall is bigger; Generally therefrom separate, the wall control from the left and right sides is simultaneously outside flue; There is interlock that the backboard of the front apron of reheater side and superheater side is coupled together operation simultaneously, like this, increased technology manufacturing and field erected difficulty on the one hand; On the other hand, because the structure of original reheater temperature adjustment baffle plate causes in field operator's operating process often because carelessness; Ignorance causes thermoregulation effect can not reach design effect reheater and chain the hanging up of superheater temperature adjustment baffle plate.
Summary of the invention
A kind of boiler flue temperature adjustment baffle plate provided by the invention, interlock is simple, makes easy for installation, regulate flexible, better adaptability, thermoregulation effect is good.
In order to achieve the above object, the present invention provides a kind of boiler flue temperature adjustment baffle plate, and this temperature adjustment baffle plate comprises front apron and backboard, and in the flue, backboard was arranged in the rear pass before described front apron was arranged on;
Described front apron and backboard are parallel to Zuo Qiang and right wall setting;
Described front apron and backboard are set to coaxial interlock, and the position of front apron and backboard is vertical each other, immobilizes.
Pass through the operation that universal driving shaft is controlled front apron and backboard from front wall or back wall.
The length of described front apron and backboard and width respectively with the degree of depth of preceding flue and rear pass and width coupling.
The present invention has the following advantages:
1, makes reheater, superheater temperature adjustment interlock become simple, the only situation of a moving side can not take place again, reduced operations staff's burden.
2, the arrangement of temperature adjustment baffle plate is changed into be parallel to left and right sides wall, the length of temperature adjustment baffle plate reduces greatly, is more prone to making in the processing.
3, the arrangement of temperature adjustment baffle plate is changed into be parallel to left and right sides wall, make that reheater steam temperature bias adjustment is more simple on width, increased a kind of method of controlling the reheater local overheating.
Description of drawings
Fig. 1 is the front view that the position is set that the present invention provides a kind of boiler flue temperature adjustment baffle plate.
Fig. 2 is the vertical view that the position is set that the present invention provides a kind of boiler flue temperature adjustment baffle plate.
Fig. 3 is the structural representation that the present invention provides a kind of boiler flue temperature adjustment baffle plate.
The specific embodiment
Following according to Fig. 1 and Fig. 2, specify preferred embodiment of the present invention:
As depicted in figs. 1 and 2; A kind of boiler flue temperature adjustment baffle plate provided by the invention comprises front apron 1, and (front apron is a reheater temperature adjustment baffle plate with backboard 2; Backboard is a superheater temperature adjustment baffle plate), among the flue F, backboard 2 was arranged among the rear pass B before described front apron 1 was arranged on.
Described front apron 1 is parallel to left wall 33 with backboard 2 and is provided with right wall 44.
As shown in Figure 3, described front apron 1 is set to coaxial interlock with backboard 2, and the position of front apron 1 and backboard 2 is vertical each other, immobilizes.
Pass through the operation that universal driving shaft is controlled front apron 1 and backboard 2 from front wall 11 or back wall 22.
The length L of described front apron 1 and backboard 2 and width D are mated with the degree of depth and the width of preceding flue F and rear pass B respectively.
Although content of the present invention has been done detailed introduction through above-mentioned preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.After those skilled in the art have read foregoing, for multiple modification of the present invention with to substitute all will be conspicuous.Therefore, protection scope of the present invention should be limited appended claim.
