Abstract
The utility model discloses a hearth structure for improving the heat exchange efficiency of an industrial furnace flameless heating section. A plurality of turbulent flow walls are vertically arranged on the top surface and the bottom surface of the furnace flameless heating section respectively at intervals. By the aid of the hearth structure, the heat exchange efficiency of the industrial furnace flameless heating section is improved effectively, heat-exchange heat resistance is reduced, and the heating efficiency of a furnace is improved.
Description
Technical field
The utility model relates to a kind of chamber structure that improves industrial furnace nonflame bringing-up section heat exchange efficiency.
Background technology
General industry stove nonflame bringing-up section is through type, and strand heats by flue gas in the middle of being located at bringing-up section.Usually the flue gas main flow of bringing-up section zone flow velocity is higher, but flue gas and strand carry out that the boundary layer flow velocity of heat exchange is lower, and the heat exchange thermal resistance is bigger, causes fume afterheat not carry out sufficient heat convection with strand, cause nonflame bringing-up section heat exchange efficiency to reduce, reduced the efficiency of heating surface of stove.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of chamber structure that improves industrial furnace nonflame bringing-up section heat exchange efficiency, this chamber structure has effectively improved the heat exchange efficiency of industrial furnace nonflame bringing-up section, reduce the heat exchange thermal resistance, improved the efficiency of heating surface of stove.
For solving the problems of the technologies described above, the chamber structure that the utility model improves industrial furnace nonflame bringing-up section heat exchange efficiency comprises the end face of nonflame bringing-up section and bottom surface, some flow-disturbing walls, and described some flow-disturbing walls are vertical at the end face and the bottom surface of described nonflame bringing-up section respectively at interval.
Further, every 10 meters, the end face of described nonflame bringing-up section and bottom surface be vertical at interval respectively to be provided with 1-5 flow-disturbing wall along nonflame bringing-up section flow of flue gas direction.
Further, the end face of above-mentioned some flow-disturbing walls is continuous or has 1-5 crenel at interval.
Further, the corresponding cis-position of the crenel of above-mentioned some flow-disturbing wall end faces is arranged or corresponding dislocation arrangement.
Further, the height of above-mentioned some flow-disturbing walls is the 5%-40% of flow of flue gas overall depth of section.
Adopted technique scheme because the utility model improves the chamber structure of industrial furnace nonflame bringing-up section heat exchange efficiency, promptly vertical at interval respectively some flow-disturbing walls have been set in the end face of stove nonflame bringing-up section and bottom surface.This chamber structure has effectively improved the heat exchange efficiency of industrial furnace nonflame bringing-up section, has reduced the heat exchange thermal resistance, has improved the efficiency of heating surface of stove.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the schematic diagram of the utility model chamber structure,
Fig. 2 is the structural representation of band crenel flow-disturbing wall in the utility model chamber structure.
The specific embodiment
As depicted in figs. 1 and 2, the chamber structure that the utility model improves industrial furnace nonflame bringing-up section heat exchange efficiency comprises the end face 11 of nonflame bringing-up section 1 and bottom surface 12, some flow-disturbing walls 2, and described some flow-disturbing walls 2 are vertical at the end face 11 and the bottom surface 12 of described nonflame bringing-up section 1 respectively at interval.
Further, every 10 meters, the end face 11 of described nonflame bringing-up section 1 and bottom surface 12 be vertical at interval respectively to be provided with 1-5 flow-disturbing wall 2 along nonflame bringing-up section 1 flow of flue gas direction.
Further, the end face of above-mentioned some flow-disturbing walls 2 is continuous or has 1-5 crenel 21 at interval.Crenel 21 the circulation area that has guaranteed flue gas is set.
Further, the crenel 21 corresponding cis-positions of above-mentioned some flow-disturbing wall 2 end faces are arranged or corresponding dislocation arrangement.When crenel 21 corresponding cis-positions are arranged, guaranteed that flue gas can pass through smoothly; And the corresponding dislocation of crenel 21 is when arranging, flue gas need go for a stroll by, further destroyed the laminar boundary layer of flue gas, improved the heat exchange efficiency of flue gas and strand 3.
Further, the height of above-mentioned some flow-disturbing walls 2 is the 5%-40% of flow of flue gas overall depth of section.
The flow-disturbing wall 2 that this chamber structure is provided with in the end face 11 of nonflame bringing-up section 1 and bottom surface 12 has destroyed the laminar boundary layer of flue gas and strand 3 in the nonflame bringing-up section 1, improve flue gas and press close to the flow velocity on strand 3 surfaces, allow the mass air flow strand 3 of trying one's best carry out enhanced heat exchange simultaneously, thereby improve the convection transfer rate of flue gas and strand 3, improve the heat exchange efficiency of strand 3, adopted this chamber structure can make the nonflame bringing-up section thermal efficiency improve 5%-10%.
