A grid type spoiler device for a plate type converter

Abstract

The invention discloses a grid-type spoiler device for a plate heat exchanger, which belongs to the technical field of heat exchangers and includes an upper baffle, a lower baffle, a front fixing plate and a rear fixing plate, an upper baffle, a lower baffle, The edges of the front fixing plate and the rear fixing plate are connected to each other to form a rectangular frame; several equidistant heat exchange plates are installed in the rectangular frame, and the heat exchange plates separate the inner space of the rectangular frame to form the same heat exchange channel, and the heat exchange channel is installed The angle-adjustable grille spoiler mechanism drives multiple incomplete gears to move uniformly when the telescopic bar moves, so that the baffle bar on the rotating shaft also moves. When the baffle bar moves, it can be changed. The airflow direction in the hot channel moves the airflow speed, which changes at any time according to different airflow requirements, and the contact area between the baffle strip and the airflow is relatively large, and a large amount of heat contained in the airflow contacts the baffle strip during the airflow movement , so that the heat is quickly transferred to the baffle bar, and then transferred to the heat exchange plate.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a grid-type flow turbulence device for a plate heat exchanger. Background technique [0002] In the field of energy saving and emission reduction, in order to utilize the waste heat in flue gas (or other gases), people have developed a plate heat exchanger, such as Figure 1 , this plate heat exchanger is suitable for heat exchange between gas and gas. It is characterized by compact structure, high heat exchange efficiency and low cost; but it also has shortcomings. First, due to the thin heat exchange plate, the stability It is very poor, the service life is very short, and it has almost no practical value. Secondly, parallel channels are formed between the heat exchange plates. When the gas passes through, it is basically a laminar flow, which seriously affects the improvement of heat exchange efficiency. Various types of corrugations are punched up to improve the rigid...

[0002] In the field of energy saving and emission reduction, in order to utilize the waste heat in flue gas (or other gases), people have developed a plate heat exchanger, such as Figure 1 , this plate heat exchanger is suitable for heat exchange between gas and gas. It is characterized by compact structure, high heat exchange efficiency and low cost; but it also has shortcomings. First, due to the thin heat exchange plate, the stability It is very poor, the service life is very short, and it has almost no practical value. Secondly, parallel channels are formed between the heat exchange plates. When the gas passes through, it is basically laminar flow, which seriously affects the improvement of heat exchange efficiency. Various types of corrugations are punched up to improve the rigidity, stability and turbulent state of the heat exchange plate, prolonging the service life of the plate heat exchanger and improving the heat exchange efficiency; however, the wave height of the suppressed corrugation will not Too high restriction leads to the limitation of the spacing between the heat exchange plates (the spacing between the heat exchange plates is twice the wave height), which leads to the limitation of the passing capacity of the gas, and the impurities in the gas are easily Block the narrow corrugated channel; in addition, the heat exchange plate will be thinned and damaged during the process of suppressing the corrugation
