Cold water heating device based on suspended kang

[0023] A device for heating cold water based on hanging kang, including right partition wall 2, kang panel 3, front kang wall 10, rear kang wall 11, left partition wall 17 and lower kang board 5; said right partition wall 2, kang panel 3 , The front kang wall 10, the back kang wall 11, the left partition wall 17 and the lower kang board 5 form a closed hollow cuboid structure; the right partition wall 2 is provided with a smoke inlet 1; the left partition wall 17 is opened There is a smoke outlet 18; the smoke outlet 18 communicates with the chimney 16; the chimney 16 is connected to the left partition wall 17; the chimney 16 is a hollow structure and is parallel to the left partition wall 17; the front kang wall 10. The back kang wall 11 is provided with a water outlet pipe 13 and a water inlet pipe 12 respectively; one end of the water outlet pipe 13 and the water inlet pipe 12 are both placed on the outer side of the front kang wall 10 and the back kang wall 11, and the other end is respectively connected with heat exchange The pipe 14 is connected; the water inlet pipe 12, the water outlet pipe 13 and the heat exchange pipe 14 form a passage; the heat exchange pipe 14 is placed on the upper end surface of the lower Kang plate 5.

[0024] Wherein, the upper end surface of the lower kang board 5 is also provided with several kang inner pillar bricks 6. The upper end surface of the lower Kang board 5 is provided with a front smoke blocking wall 7; the front smoke blocking wall 7 is close to the smoke inlet 1. The upper end surface of the lower Kang board 5 is provided with a rear smoke blocking wall 8; the rear smoke blocking wall 8 is close to the smoke outlet 18. The front smoke blocking wall 7 is a herringbone structure. The rear smoke blocking wall 8 is a herringbone structure. The lower end surface of the lower kang board 5 is provided with several kang legs 4. A smoke insert 15 is provided in the middle section of the chimney 16; the smoke insert 15 communicates with the chimney 16. The inner side of the back kang wall 11 is provided with an insulation layer 9.

[0025] The present invention will be further described below in conjunction with the drawings. Such as figure 1 , As shown in 2, the water inlet pipe 12 is arranged on the side of the rear kang wall 11, and the distance from the right partition wall 2 is 110 mm. The outlet pipe 13 is arranged on the side of the front wall 10, and the distance from the rear smoke blocking wall 8 is 110 mm. The water inlet pipe 12 and the water outlet pipe 13 are 53 mm away from the upper surface of the lower kang board 5 (the distance of a brick), and are placed in the air. The heat exchange tube 14 is made of steel pipe, and is arranged in a "rectangular pulse shape" around the pillar bricks inside the kang. When building the inner wall of the kang, leave a gap of 40mm on the wall of the back kang wall 11 as the insulation layer 9. The insulation layer 9 is filled with refractory insulation materials such as perlite or dry fine slag ash, and compacted, and fine grass sand is used on the four sides. Wiped strictly. The top of the kang panel 3 is slightly lower than the kang head, the top of the kang is slightly higher than the bottom of the kang, and the surrounding area is slightly higher than the middle (the height difference is controlled within 30mm). The entire kang surface is "curled" and is more conducive to heat storage. The front smoke blocking wall 7 and the rear smoke blocking wall 8 are herringbone-shaped smoke dividing walls, which can eliminate the four dead corners of the kang tip and the head, so that the temperature of the kang surface is heated more uniformly, and the human body comfort is improved. At the same time, the rear smoke barrier 8 can prevent smoke Directly into the chimney, the flue gas changes from a rapid flow to a slow flow, which prolongs the heat dissipation time, reduces the exhaust gas temperature, and improves the utilization rate of heat.

[0026] This embodiment realizes the heat exchange between flue gas and cold water through the heat exchange tubes arranged in the "rectangular pulse" arrangement in the hanging chimney flue. Part of the energy released by fuel combustion is used to heat water. The heated water can be used directly. The temperature of the water is The season is related to the heating time of the kang. Generally, the time for making a meal is set to one hour, during which the room temperature water can be heated to 40-50℃, and the temperature of the kang noodles can be controlled at about 20℃. Compared with direct heating of cold water, it can reduce fuel. The heat exchange tube can change the flow state of the flue gas from rapid flow to slow flow, extend the heat dissipation time, reduce the exhaust gas temperature, and at the same time avoid the high temperature of the kang head caused by too long cooking time (too long cooking time) And the indoor temperature is too high in summer.

[0027] The embodiments are preferred embodiments of the present invention, but the present invention is not limited to the above-mentioned embodiments. Without departing from the essence of the present invention, any obvious improvements, substitutions or substitutions can be made by those skilled in the art. All variants belong to the protection scope of the present invention.
