Abstract

The utility model discloses a heat exchanger for smoke waste heat recovery. The heat exchanger comprises finned pipes, wherein the finned pipes are at least arranged in two rows; and the two adjacent rows of finned pipes are orthogonally arranged. The heat exchanger has the benefits of high heat exchange efficiency and low cost.

Description

A kind of heat exchanger of flue gas waste heat recovery
Technical field the present invention relates to a kind of heat exchanger, is more particularly to a kind of heat exchanger of flue gas waste heat recovery, belongs to the field of heat exchangers of flue gas waste heat recovery.
The raising heat-transfer capability technological direction of the present domestic finned tube exchanger of background technology is more and more meticulousr and high-end; But the ubiquity heat exchange efficiency is low between heat exchanger heat-exchanging tube external agency inside; Type of flow stratified flow flows between medium and tube wall and the fin; Energy between the medium mainly slowly transmits by conduction, and formation temperature gradient phenomenon is so cause heat exchange efficiency to reduce.The heat exchanger of present existing flue gas waste heat recovery comprises: finned tube, and finned tube is arranged in a row; Thereby exchange capability of heat is low.So the improvement of the heat exchanger of present existing flue gas waste heat recovery is: through in heat exchanger, increasing plug-in unit or using measure such as bellows instead and improve heat exchange efficiency.But this improvement produces expensive and inefficient result.
Summary of the invention the objective of the invention is to overcome above deficiency, provides: the heat exchanger of the flue gas waste heat recovery that a kind of heat exchange efficiency is high, cost is low.
A kind of heat exchanger of flue gas waste heat recovery comprises: finned tube, finned tube are lined up two rows at least, carry out orthogonal arrangement between two contiguous row's finned tubes.
Also comprise: L shaped water-inlet header and L shaped goes out water manifold, and an end of two row's finned tubes of contiguous orthogonal arrangement connects water-inlet header, and the other end connects water manifold.
The invention has the beneficial effects as follows:
Because: a kind of heat exchanger of flue gas waste heat recovery comprises: finned tube, finned tube are lined up two rows at least, carry out orthogonal arrangement between two contiguous row's finned tubes; Thereby: the quadrature of finned tube has played the effect of blender, makes the medium interior temperature distribution more even, and then can carry out heat transmission more fully sooner, improves the heat transfer temperature difference of the inside and outside medium of finned tube, improves heat exchange efficiency greatly; And: form strong random turbulent flow and additional perturbing area between the outer medium of finned tube pipe; Carry out orthogonal arrangement between two contiguous row's finned tubes, increased turbulence effect; This just makes heat transferring medium inside can carry out heat transmission more fully sooner, reduces the local temperature difference between the medium, improves the heat transfer temperature difference of the inside and outside medium of finned tube, thereby improves heat exchange efficiency; So: the present invention has reached the purpose that heat exchange efficiency is high, cost is low.
Because: also comprise: L shaped water-inlet header and L shaped goes out water manifold, and an end of two row's finned tubes of contiguous orthogonal arrangement connects water-inlet header, and the other end connects water manifold; Thereby: cold water can get into water-inlet header from the water inlet of water-inlet header, and then gets in the finned tube of orthogonal arrangement, gets into out water manifold again, and discharges from the delivery port that goes out water manifold; Flue gas is through the finned tube of orthogonal arrangement, passes to the finned tube of orthogonal arrangement to waste heat, and then waste heat passes in the water that flows in the finned tube of orthogonal arrangement; What discharge from the delivery port that goes out water manifold is exactly hot water, and the waste heat of flue gas just has been recovered.
In sum, heat exchange efficiency of the present invention is high, cost is low.

The specific embodiment is elaborated to the present invention below in conjunction with accompanying drawing
A kind of heat exchanger of flue gas waste heat recovery comprises: finned tube 1, finned tube 1 is lined up two rows at least, carries out orthogonal arrangement between two contiguous row's finned tubes.Also comprise: L shaped water-inlet header 2 goes out water manifold 3 with L shaped, and an end of two row's finned tubes of contiguous orthogonal arrangement connects water-inlet header 2, and the other end connects water manifold 3.
Because: a kind of heat exchanger of flue gas waste heat recovery comprises: finned tube 1, finned tube 1 is lined up two rows at least, carries out orthogonal arrangement between two contiguous row's finned tubes; Thereby: the quadrature of finned tube 1 has played the effect of blender, makes the medium interior temperature distribution more even, and then can carry out heat transmission more fully sooner, improves the heat transfer temperature difference of finned tube 1 inside and outside medium, improves heat exchange efficiency greatly; And: form strong random turbulent flow and additional perturbing area between the outer medium of finned tube 1 pipe; Carry out orthogonal arrangement between two contiguous row's finned tubes, increased turbulence effect; This just makes heat transferring medium inside can carry out heat transmission more fully sooner, reduces the local temperature difference between the medium, improves the heat transfer temperature difference of finned tube 1 inside and outside medium, thereby improves heat exchange efficiency; So: the present invention has reached the purpose that heat exchange efficiency is high, cost is low.
Because: also comprise: L shaped water-inlet header 2 goes out water manifold 3 with L shaped, and an end of two row's finned tubes of contiguous orthogonal arrangement connects water-inlet header 2, and the other end connects water manifold 3; Thereby: cold water can get into water-inlet header 2 from the water inlet of water-inlet header 2, and then gets in the finned tube 1 of orthogonal arrangement, gets into out water manifold 3 again, and discharges from the delivery port that goes out water manifold 3; Flue gas is through the finned tube 1 of orthogonal arrangement, passes to the finned tube 1 of orthogonal arrangement to waste heat, and then waste heat passes in the water that flows in the finned tube 1 of orthogonal arrangement; What discharge from the delivery port that goes out water manifold 3 is exactly hot water, and the waste heat of flue gas just has been recovered.
In sum, heat exchange efficiency of the present invention is high, cost is low.
