Technical Field

Background

The gas module furnace is a central heating gas device, and a plurality of gas module furnaces are commonly combined for use because of the smaller power of a single gas module furnace. A common combination is to mount a plurality of gas module furnaces on the same condensing module. The high-temperature flue gas generated by the gas module furnace is uniformly discharged into the condensing module after being subjected to heat exchange with the main heat exchanger of the gas module furnace, and then is subjected to heat exchange with the heat exchanger in the condensing module, so that latent heat in the flue gas is fully absorbed, and the overall energy efficiency of the equipment is improved. The problem with existing condensing modules is that: the existing condensation modules are mostly finned tube heat exchangers, and the space between the finned tubes is designed to be smaller in order to increase the heat exchange area and ensure the heat exchange efficiency. The flue gas direction is opposite to the dripping direction of the condensed water, and the viscosity tension characteristic of the water is added, so that when a large amount of condensed water is generated, the condensed water is easily attached to the surface of the finned tube and cannot flow down, thereby blocking a flue gas channel and affecting the combustion and efficiency of the equipment.

Please refer to fig. 1-3, which are respectively perspective views of the centralized condensing structure of the gas module unit and cross-sectional views of the centralized condensing structure in the directions A-A, B-B, C-C. For ease of illustration, the cross-sectional view employs an isometric view.

The concentrated condensation structure of the gas module unit comprises a flue 1, a condensation chamber 2 and a wind collecting cover 3 which are sequentially arranged from bottom to top.

The flue 1 is a flat, long-strip hollow cavity, the lower end is closed, the upper end is open, the left and right sides are provided with side connecting plates 11, and the left and right positions of the bottom are provided with bottom connecting plates 12. The side connection plates 11 and the bottom connection plates 12 are used for connection with the gas module furnace.

The flue 1 is provided with a flue gas partition 13 extending up and down between the front and back surfaces to partition the interior into a left chamber 14 and a right chamber 15. The bottoms of the left and right chambers 14 and 15 are respectively provided with a drain port 16 for draining condensed water.

Two flue gas interfaces 17 are arranged on the front side of the flue 1 up and down and penetrate into the right chamber 15; two flue gas interfaces 17 are arranged on the back side, and penetrate into the left chamber 14. The flue gas interface 17 is used for interfacing with the flue gas duct of the gas module furnace.

The inner wall of one surface of the smoke interface 17 is arranged in the left chamber, and a smoke baffle 18 is arranged below the upper smoke interface 17. A smoke baffle 18 is also provided in the right chamber at the same position, i.e. on the inner wall opposite the left chamber.

The condensing chamber 2 is a square cavity, the bottom of the condensing chamber is connected with the top of the flue 1, one long side of the bottom, which is close to the back, is aligned with the edge position of the side connecting plates 11, which is close to the back of the flue 1, the wide sides of the bottom are respectively aligned with the two side connecting plates 11, and one long side of the bottom, which is close to the front, extends out of the flue 1. Between the flue 1 and the condensation chamber 2, only one opening is arranged in a half area of the backrest surface, and the other plate area is covered by the bottom plate of the condensation chamber 2.

The condensing chamber 2 is internally provided with a heat exchanger at a position close to the front, and in order to avoid mess of pictures, the heat exchanger is not drawn in the drawing, and only a pipeline port 21 for the pipeline of the heat exchanger to go in and out is drawn. Therefore, the side of the back surface in the condensing chamber 2 is not provided with a heat exchanger, namely, the position right above an opening between the flue 1 and the condensing chamber 2 is kept clear, and no heat exchanger covers.

A piece of L-shaped flue gas deflector 22 is arranged in the condensing chamber 2 between the heat exchanger and the wind collecting cover 3 and between the heat exchanger and a piece of side wall of the condensing chamber close to the front face, and an opening is arranged on the part between the heat exchanger and a piece of side wall of the condensing chamber close to the front face.

The bottom in the condensing chamber 2 is positioned at one side of the opening of the flue 1 close to the back surface and is provided with an inclined baffle plate which is marked as a flue gas guide plate 23; a tilted baffle plate, denoted as condensate guide plate 24, is provided at a position between the flue gas guide plate 22 and the bottom of the condensing chamber 2, at the front side of the opening of the flue 1, below the heat exchanger.

When in use, the four gas module furnaces are respectively arranged on the front side and the back side of the flue 1, and the smoke exhaust pipelines of the four gas module furnaces are respectively connected into the flue 1 through the four smoke interfaces 17.

The flue gas generated by the fuel gas module furnace is concentrated into the flue 1 through a flue gas interface 17; the flue gas baffle 18 is upwards bypassed, and the flue gas passes through an opening between the flue 1 and the condensing chamber 2 and enters the condensing chamber 2; under the limitation of the flue gas guide plate 22, the flue gas can only turn to the heat exchanger and pass through the opening of the flue gas guide plate 22 to the interlayer between the flue gas guide plate 22 and the condensing chamber 2; finally, flows upwards into the wind collecting cover 3 and is discharged from the top end of the wind collecting cover 3.

In the process that the flue gas turns in the condensing chamber 2 and flows to the heat exchanger, the flue gas guide plate 23 plays a guiding role, so that turbulence generated in the turning process of the flue gas is reduced.

The flowing direction of the flue gas is perpendicular to the dropping direction of the condensed water, so that the condensed water is not blocked. The condensed water produced by the heat exchanger drops onto the condensed water guide plate 24 and the bottom of the condensing chamber 2, flows to the opening between the flue 1 and the condensing chamber 2, finally drops to the bottom of the flue, and is discharged from the two water discharge ports 16 respectively.
