Abstract
The utility model provides a novel vertical guiding gutter protection device relates to the thermal power field. This novel vertical guiding gutter protection device, including the guiding gutter body, the last fixed surface of guiding gutter body is connected with the mounting panel, the opening with guiding gutter body looks adaptation is seted up to the mounting panel. This novel vertical guiding gutter protection device through setting up guiding gutter body and opening, can make the opening just to the flue gas, and the most flue gas of here of flowing through can be flowed backwards downwards by the refluence, and the flue gas is not cut apart, and simultaneously, the guiding gutter body is little clearance fit with both sides pipeline, only has few part flue gas to flow through, but the little vortex of formation can only rub the guiding gutter back to the protection pipeline is not rubbed and is corroded.
Description
Technical Field
The utility model relates to a thermal power technology field specifically is a novel vertical guiding gutter protection device.
Background
Thermal power generation is a power generation mode that thermal energy generated by combustible materials during combustion is converted into electric energy through a power generation power device, and a boiler of a thermal power station is one of main thermal equipment of a thermal power plant. As most of power station boilers are designed to be of a pi-shaped structure, and the bottom wrapping wall of the horizontal flue is designed to be in a slope form, smoke can turn and accelerate downwards after passing through a flame folding angle, directly impact a pipeline at an included angle formed by the front row of hanging pipes and the horizontal heating surface, and form smoke vortex on the smoke facing side of the pipeline, and the smoke vortex rubs with the pipeline for a long time to cause the blowing loss and thinning of the pipeline.
The original design of the boiler does not consider the blowing loss condition of the pipeline at the position, measures such as a left-hand buckle arc-shaped anti-abrasion tile and an additional flow blocking device are adopted according to other power plants in the industry, vortex formed by smoke at the position cannot be effectively solved, the actual effect is not ideal enough, and even the damage to other parts of the pipeline is brought.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a novel vertical guiding gutter protection device can solve the problem in the above-mentioned.
In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a novel vertical guiding gutter protection device, includes the guiding gutter body, the last fixed surface of guiding gutter body is connected with the mounting panel, the opening with guiding gutter body looks adaptation is seted up to the mounting panel.
Further, the length of the diversion trench body is 1.4M, and the section of the diversion trench body is in an isosceles trapezoid shape.
Compared with the prior art, this novel vertical guiding gutter protection device possesses following beneficial effect: this novel vertical guiding gutter protection device is through setting up guiding gutter body and opening, can make the opening just to the flue gas, and the most flue gas that flows through here can be flowed backwards downwards by the refluence, and the flue gas is not cut apart. Meanwhile, the diversion trench body is in small clearance fit with the pipelines at two sides, only a small part of smoke flows through, but the formed small eddy current only rubs the back of the diversion trench, so that the pipelines are protected from being abraded; the length that sets up the guiding gutter is 1.4M, and its cross sectional shape is isosceles trapezoid, has certain deflection, the installation and the dismantlement of being convenient for, compares with current technique, and this novel vertical guiding gutter simple structure makes at the bottom of the precision, and low in production cost is applicable to all boilers that adopt pi type structure, can carry out nimble adjustment to the structure size according to on-the-spot actual conditions.
Drawings
FIG. 1 is a front structural view of the present invention;
FIG. 2 is a schematic view of the upper surface structure of the present invention;
fig. 3 is a schematic side view of the present invention.
Wherein, 1, the diversion trench body; 2. mounting a plate; 3. and (4) opening.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1-3, the embodiment of the present invention provides a novel vertical diversion trench protection device, which comprises a diversion trench body 1, wherein the length of the diversion trench body 1 is 1.4M, the cross section of the diversion trench body 1 is isosceles trapezoid, so that the diversion trench has a certain deformation, the structure size can be flexibly adjusted according to the actual situation on site, the mounting plate 2 is fixedly connected to the upper surface of the diversion trench body 1, the diversion trench can be conveniently mounted and dismounted, the diversion trench is suitable for all boilers adopting a pi-shaped structure, the mounting plate 2 is provided with an opening 3 matched with the diversion trench body, the opening 3 can be opposite to the flow direction of flue gas, when the flue gas flows through the horizontal flue, the flue gas can directly impact on the diversion trench, and the flue gas can flow downwards under the blocking of the trapezoidal trench, so that most of the flue gas is blocked from scouring the suspension pipe and the horizontal pipe, and the suspension pipe and the horizontal pipe are protected from being damaged.
The working principle is as follows: this guiding gutter is when using, make opening 3 just to the flue gas flow direction, utilize mounting panel 2 to install the guiding gutter behind the horizontal flue between first row hangs pipe and the horizontal pipe, can directly strike on the guiding gutter when the flue gas flows through the horizontal flue, the cross-sectional shape of guiding gutter body 1 is isosceles trapezoid, the flue gas can be down stream and down under blockking of dovetail groove, it erodees hanging pipe and horizontal pipe to block most flue gas, only a small part flue gas can flow through from the booth clearance between guiding gutter and the horizontal pipe, this part flue gas can form small-size vortex at the guiding gutter back, but because its back all has the certain distance with hanging pipe and horizontal pipe, consequently can not harm the pipeline. After the diversion trench is additionally arranged, the heating of the suspension pipe and the horizontal pipe cannot be influenced.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
