Condensation heat exchanger

Technical Field

The invention belongs to the technical field of gas heating water heaters, and particularly relates to a condensation heat exchanger.

Background

Because the internal water channel of the heat absorption component is filled with cold water, when energy exchange is carried out between the heat absorption component and rising hot air, water vapor in the hot air can be condensed on the wall surface of the heat absorption component when meeting cold, and the heat exchange efficiency is influenced; meanwhile, condensed water is gathered and then slides downwards under the action of self weight, so that water is accumulated in the equipment.

Disclosure of Invention

The invention aims to provide a condensation heat exchanger, wherein flue gas enters a heat absorption assembly from top to bottom, and a drainage structure is arranged below the heat absorption assembly, so that the problem of condensed water discharge is solved, and the heat efficiency is improved.

The purpose of the invention is realized as follows: a condensation heat exchanger comprises a smoke channel and a heat absorption assembly arranged on the smoke channel, wherein the smoke channel enters from the upper end face of the heat absorption assembly, the lower end face of the smoke channel is discharged, an inclined water baffle is arranged below the heat absorption assembly, and a water outlet is formed in the lower end of the water baffle.

Furthermore, a smoke hood covers the heat absorption assembly, a smoke inlet is formed in the bottom surface of the smoke hood, and a smoke outlet is formed in the top of the smoke hood; the smoke hood and the water baffle form the smoke channel, and the heat absorption assembly is transversely arranged on the smoke channel.

Further, the flue gas passageway is the Z type trend, smoke cover one side sets up the chimney.

Furthermore, the lateral wall of the smoke hood is provided with a drainage pipeline which is in butt joint with the drainage outlet.

Furthermore, the lateral wall of the smoke hood is provided with a water inlet connector and a water outlet connector which are butted with the internal waterway of the heat absorption assembly.

Furthermore, a water collecting groove is arranged at the lower end of the water baffle, and a water outlet is formed in the end portion of the water collecting groove.

Furthermore, the heat absorption assembly comprises heat absorption pipes and heat absorption sheets, the heat absorption pipes are arranged in parallel and are communicated with each other through water boxes at the end parts, and the heat absorption sheets are fixed on the outer sides of the heat absorption pipes.

Compared with the prior art, the invention has the outstanding and beneficial technical effects that: the flow direction of the condensed water is consistent with that of the flue gas, so that the condensed water on the surface of the heat absorption component is reduced; due to the arrangement of the water baffle structure, the condensed water is discharged in time, and the influence of acidic condensed water on the inside of equipment is avoided.

Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

A condensation heat exchanger, see in particular fig. 3, comprises a flue gas channel (indicated by arrows) and a heat absorbing assembly 4 placed transversely to the flue gas channel. In this embodiment, the flue gas channel is overall in a zigzag trend, and the flue gas firstly enters from the flue gas inlet 1a at the bottom of the smoke hood 1, then rises from the left side of the heat absorption assembly 4, enters from the upper end face of the heat absorption assembly 4, and is discharged from the lower end face, and then rises from the right side of the heat absorption assembly 4 and is discharged from the flue gas outlet 1 b.

Wherein, the specific structure of petticoat pipe 1 is the L type, forms chimney 5 structure on one side. The inclined water baffle plate 2 is arranged below the heat absorption component 4, the water baffle plate 2 guides the smoke to the left side of the heat absorption component 4 and is guided to the top of the heat absorption component 4 by the smoke hood 1, the smoke enters from the upper end face of the heat absorption component 4 under the action of a fan (arranged at a smoke outlet 1b), the smoke is discharged from the lower end face, and the smoke is guided to a chimney 5 on the right side of the heat absorption component 4 by the water baffle plate 2 and is discharged upwards.

With reference to fig. 3 and 5, the water baffle 2 also functions to collect the condensed water flowing down from the heat absorbing assembly 4 and make the condensed water flow to the lower end of the water baffle 2, where a water collecting tank is arranged and the condensed water is discharged from the water outlet 2a in butt joint with the water discharge pipeline 3.

With reference to fig. 1 and 2, a water inlet interface 4a and a water outlet interface 4b which are butted with a water path inside the heat absorption assembly 4 are arranged on the side wall of the smoke hood 1, and cold water is in heat exchange with a smoke channel inside the smoke hood 1 through the channel.

Referring to fig. 4 in particular, the heat absorbing assembly 4 comprises heat absorbing pipes 4a and heat absorbing sheets 4b, the heat absorbing pipes 4a are arranged in parallel and are communicated with each other through water boxes 4c at the end parts, and the heat absorbing sheets 4b are fixed on the outer sides of the heat absorbing pipes 4 a. The gap between the heat absorption pipes is the gap through which the flue gas passes, and the flue gas passes through the gap and realizes heat exchange with the heat absorption pipes 4a and the heat absorption sheets 4b, so that the water flow in the heat absorption pipes 4a is heated.
