Abstract

The utility model discloses a coal economizer, comprising an inlet header, an outlet header and a snakelike pipe, wherein the coil pipe is connected between the inlet header and the outlet header; fins are arranged at the outside of the snakelike pipe. Multiple fins are arranged at the outside along the axial direction of the coil pipe in an array mode; the plane where each fin is positioned is vertical to the axial line of the coil pipe; the joint between each fin and the coil pipe is set to be arc by matching the outer surface of the coil pipe; the fins are symmetrically arranged at two sides of the coil pipe; the fins are connected to the outer side of the coil pipe in a welding mode; the fins are made of carbon steel. The rectangular fins are additionally arranged at two sides of the coil pipe, so a heated surface is expanded, the heat exchange efficiency is improved, air flows in a flue can form uniform flows by the actions of the fins, and the coal economizer has the advantages of compact structure, efficiency, improvement of the abrasion life and the avoidance of leaking.

Description

A kind of coal saving device
Technical field
The present invention relates to a kind of coal saving device.
Background technology
Economizer is a vitals of boiler, and its operation principle is to utilize the heating surface of the lower flue gas boiler feedwater of boiler back end ductwork temperature of flowing through, and is beneficial to improve the thermal efficiency of boiler, saves the energy.But traditional Bare Tube Economizer is because heating surface is little, therefore need the economizer of larger volume could reduce exhaust gas temperature; In addition, because the soot particle in flue can produce and impact and cutting force economizer pipeline, cause economizer wear and leakage, cause economizer normally to use.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of coal saving device, solves that economizer surface in prior art is little, the technical problem of economizer leakage easy to wear.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A coal saving device, comprises import header, outlet header and is connected in the coiled pipe between described import header and outlet header, the arranged outside of described coiled pipe has fin.
Preferably, in above-mentioned coal saving device, the outside of described coiled pipe vertically array is provided with a plurality of fins.
Preferably, in above-mentioned coal saving device, the axis of the vertical described coiled pipe of plane at described each fin place.
Preferably, in above-mentioned coal saving device, described each fin coordinates the outer surface of described coiled pipe to be set to circular arc with the joint of coiled pipe.
Preferably, in above-mentioned coal saving device, described a plurality of fins are symmetricly set in the both sides of described coiled pipe.
Preferably, in above-mentioned coal saving device, described fin is connected in the outside of described coiled pipe by welding manner.
Preferably, in above-mentioned coal saving device, the material of described fin is carbon steel.It is characterized in that: described coal saving device also comprises catalyst bracket and is fixed on the catalyst module on described catalyst bracket.
The beneficial effect of finned coal saving device of the present invention: this coal saving device is by increasing rectangular fin in coiled pipe both sides, thereby extended surface, improve heat exchange efficiency, and due to fin effect, can make the air-flow in flue form current-sharing, have simple for structure, efficient, improve wear-out life, avoid the advantage of economizer leakage.
Accompanying drawing explanation
Fig. 1 is the structural representation of coal saving device in the specific embodiment of the invention;
Fig. 2 is the side structure schematic diagram that in the specific embodiment of the invention, coiled pipe is connected with fin;
Fig. 3 is the cross-sectional view that in the specific embodiment of the invention, coiled pipe is connected with fin.
The specific embodiment
Because traditional Bare Tube Economizer is because heating surface is little, therefore need the economizer of larger volume could reduce exhaust gas temperature; In addition, because the soot particle in flue can produce and impact and cutting force economizer pipeline, cause economizer wear and leakage, cause economizer normally to use.
Technical problem to be solved by this invention is, for above-mentioned deficiency of the prior art, to provide a kind of coal saving device exactly, solves that economizer surface in prior art is little, the technical problem of economizer leakage easy to wear.
Below by embodiment, and by reference to the accompanying drawings, technical scheme of the present invention is done more specifically bright.
Embodiment 1: shown in Fig. 3, the present invention includes import header 1, outlet header 2 and be connected in the coiled pipe 4 between described import header 1 and outlet header 2, the arranged outside of described coiled pipe 4 has fin 3.
Further, the outside of described coiled pipe vertically array be provided with a plurality of fins.
Further, the axis of the vertical described coiled pipe of plane at described each fin place.
Further, described each fin coordinates the outer surface of described coiled pipe to be set to circular arc with the joint of coiled pipe.
Further, described a plurality of fin is symmetricly set in the both sides of described coiled pipe.
Further, in above-mentioned coal saving device, described fin is connected in the outside of described coiled pipe by welding manner.
Further, the material of described fin is carbon steel.
Further, described coal saving device also comprises catalyst bracket and is fixed on the catalyst module on described catalyst bracket.
In the present embodiment, when this coal saving device is moved, water at low temperature enters coiled pipe 4 through import header 1, after heat exchange, from outlet header 2, discharges.Further, described coiled pipe 4 carries out heat convection with the high-temperature flue gas in flue, and the fin 3 being connected with coiled pipe 4 can increase heating surface area, thereby improves the heat exchange efficiency of water in flue gas and coiled pipe 4, thereby greatly reduces coal charge consumption.In addition, the axis due to the vertical described coiled pipe of plane at fin 3 places, therefore fin 3 divides the space in flue for several little regions, has the effect of current-sharing to air-flow, has simple for structurely, efficient, improves wear-out life, avoids the advantage of economizer leakage.
Take the above-mentioned desirable embodiment according to this patent as enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this patented technology thought, carry out various change and modification completely.The technical scope of this patent is not limited to the content on description, must determine its technical scope according to claim scope.
