Problems solved by technology

[0005] The present invention proposes a gas-fired water heating device aiming at the deficiencies in the prior art. The gas-fired water heating device not only solves the problem that the water pipe heat exchange is sensitive to scale, but also solves the problem that the fire pipe type heat exchange water tank is under pressure.

Embodiment Construction

[0025] In order to better illustrate the present invention, further description will now be made in conjunction with the embodiments and accompanying drawings.

[0026] Such as Figure 1 to Figure 5 As shown, the gas water heating device includes a burner 100, a combustion chamber 200, a lower heat exchanger 300, a lower smoke collection chamber 400, an upper heat exchanger 500 and an upper smoke collection chamber 600 installed sequentially from bottom to top; The heat exchanger 500 is a tubular structure placed horizontally. Flanges 510 are respectively provided at both ends of the upper heat exchanger 500. There are sealing rings 520 and sealing covers 530 on the outside of the flanges 510. The sealing covers 530 and sealing covers at both ends of the upper heat exchanger 500 are The sealing ring 520 forms a closed pipeline space inside the upper heat exchanger 500; the top of the upper heat exchanger 500 is respectively provided with an outwardly extending water inlet pipe...

Abstract

The invention discloses a gas water heating device, and relates to the field of water heating devices. The gas water heating device comprises a combustor, a combustion chamber, a lower heat exchanger, a lower fume collection chamber, an upper heat exchanger and an upper fume collection chamber, which are sequentially mounted from bottom to top. The upper heat exchanger is horizontally arranged and adopts a tubular structure. Flanges are respectively arranged at two ends of the upper heat exchanger. A seal ring and a seal cover are arranged on the outer side of each flange. A water inlet pipe and a gas exhaust pipe, which extend outwards, are arranged at the top of the upper heat exchanger separately. A communicating pipe extending outwards is arranged at the bottom of the upper heat exchanger. A plurality of heat exchange pipes are arranged in the upper heat exchanger. The lower heat exchanger adopts a structure formed after the upper heat exchanger is inverted. Compared with the prior art, the gas water heating device has the advantages that the problem that water tube heat exchange is sensitive to scale is solved, the problem of bearing pressure by a fire tube type heat exchange water liner is solved, and besides, since spiral water flow generated by the heat exchange pipes increases the water flow speed, the scale precipitation is reduced, and the heat exchange efficiency is improved.

Description

technical field [0001] The invention relates to the field of hot water equipment, in particular to a condensing gas hot water device. Background technique [0002] There are two main types of heat exchange schemes for existing gas water heaters, one is water tube heat exchange, and the other is fire tube heat exchange. [0003] The water tube heat exchange is that the outside of the heat exchange tube is high-temperature flue gas, the inside is water, and the heat transfer direction is from outside the tube to the inside of the tube; while the fire tube heat exchange is that the inside of the heat exchange tube is high-temperature flue gas, the outside is water, and the heat The direction of transmission is from the inside of the tube to the outside of the tube. [0004] Because the water tube heat exchange is more sensitive to scale, it has high requirements on water quality or is generally not used to produce high-temperature hot water; while the fire tube heat exchange i...
