This economizer for power boiler includes multilayer pipeline and guard plate, and every layer of pipeline is the snakelike parallel configuration of buckling, the guard plate sets up the top at the superiors' pipeline, it has the grid hole to be the lattice -shaped distribution on the guard plate, be equipped with the fixed buckle of a plurality of on the lower surface of guard plate, every fixed buckle includes the cards that two mutual symmetries set up, the card includes the segmental arc at middle part and the straightway at segmental arc both ends, the straightway of card upper end with the lower surface of guard plate is connected, the unsettled setting of lower extreme freedom. The utility model provides a simple structure, simple to operate, firm, the explosion -proof effectual economizer for power boiler of installation.
Description
Technical field
This utility model relates to electricity generation boiler technical field, specifically a kind of electricity generation boiler economizer.
Background technology
Economizer is mounted to the interior a kind of device for recovery waste heat of boiler flue, and the heating surface of saturation water boiler feedwater being heated under drum pressure, owing to it absorbs the heat of low-temperature flue gas, reduce the exhaust gas temperature of flue gas, save the energy, improve efficiency, so referred to as economizer.Economizer is one of important heating surface of station boiler, also it is the parts of serious wear simultaneously, owing to boiler economizer in power plant is easily worn, leakage booster often occurs, forcing boiler emergency outage, safe and stable, economical operation to boiler produce the biggest adverse effect.The method installing semicircle anti-abrasion cover on current commonly used single cell additional, the shortcoming of this method is that anti-abrasion cover is easy to fall off, so, the wear problem the most thoroughly solving economizer has important realistic meaning, there is certain difficult point technically.
Utility model content
This utility model be provide a kind of simple in construction, easy for installation, firmly install, electricity generation boiler economizer that explosion-proof effect is good.
This utility model is achieved through the following technical solutions:
A kind of electricity generation boiler economizer, including multi-layer piping and protective plate, every layer of pipeline serpentine-like bending laid out in parallel, described protective plate is arranged on the top of the superiors' pipeline, grid hole is distributed in lattice-shaped on described protective plate, the lower surface of described protective plate is provided with several fixing buckles, each fixing buckle includes two cards being symmetrically set, described card includes segmental arc and the straightway at segmental arc two ends at middle part, the straightway of described card upper end is connected with the lower surface of described protective plate, lower end freely unsettled setting.
Segmental arc indent close to each other on two cards of described fixing buckle is arranged, and when described fixing buckle is in fastening state, two cards of described fixing buckle are between adjacent two pipelines.
The radian of the segmental arc on described card is more than the radian of described pipeline.
Described card upper end is by being fixedly welded on the lower surface of described protective plate.
This utility model is had the benefit that
In this utility model, described electricity generation boiler economizer constructs, install, overhaul convenient and swift, and described protective plate is connected with pipeline by fixing buckle, solid and reliable, difficult drop-off and damage, furthermore, abrasionproof is effective, described protective plate uses lattice structure design, grid design becomes certain thickness, when flue gas is by grid, owing to the effect of grid can make the flue gas of the big flow in local freely disperse, reduce flue gas and directly wash away the speed of pipeline, can effectively prevent the abrasion of economizer.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Fig. 1 is the structural representation of electricity generation boiler economizer described in the utility model.
Fig. 2 is the side view of electricity generation boiler economizer described in the utility model.
The label that in figure, component names is corresponding is as follows:
1, pipeline；2, protective plate；3, grid hole；4, card.
Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is described in further detail by embodiment:
Embodiment as electricity generation boiler economizer described in the utility model, as depicted in figs. 1 and 2, including multi-layer piping 1 and protective plate 2, every layer of pipeline 1 serpentine-like bending laid out in parallel, described protective plate 2 is arranged on the top of the superiors' pipeline 1, grid hole 3 is distributed in lattice-shaped on described protective plate 2, the lower surface of described protective plate 2 is provided with four fixing buckles, each fixing buckle includes two cards being symmetrically set 4, described card 4 includes segmental arc and the straightway at segmental arc two ends at middle part, the straightway of described card 4 upper end is connected with the lower surface of described protective plate 2, lower end freely unsettled setting.Described electricity generation boiler economizer constructs, install, overhaul convenient and swift, and described protective plate 2 is connected with pipeline 1 by fixing buckle, solid and reliable, difficult drop-off and damage, furthermore, abrasionproof is effective, and described protective plate 2 uses lattice structure to design, and grid 3 is designed to certain thickness, when flue gas is by grid 3, owing to the effect of grid 3 can make the flue gas of the big flow in local freely disperse, reduce flue gas and directly wash away the speed of pipeline, can effectively prevent the abrasion of economizer.
In the present embodiment, the segmental arc indent close to each other on two cards 4 of described fixing buckle is arranged, and when described fixing buckle is in fastening state, two cards 4 of described fixing buckle are between adjacent two pipelines 1.This kind of fixed form is the most firm, it is not easy to come off.
In the present embodiment, the radian of the segmental arc on described card 4 is more than the radian of described pipeline 1.
In the present embodiment, described card 4 upper end is by being fixedly welded on the lower surface of described protective plate 2.
Certainly, the lower surface of described protective plate can also be provided with three or five or six or eight fixing buckles.So, the most all within this utility model protection domain, repeat the most one by one.
