Detailed Description

The present invention is further described below in conjunction with the following figures and specific examples so that those skilled in the art may better understand the present invention and practice it, but the examples are not intended to limit the present invention.

Referring to fig. 1, the heat exchanger according to an embodiment of the present invention includes a heat exchange box 1 and a combustion heat supply device 2, a flue gas pipe 3 extending into the heat exchange box 1 is connected to the combustion heat supply device 2, the flue gas pipe 3 includes a flue gas header pipe, one end of the flue gas header pipe is provided with a plurality of flue gas branch pipes, a heat exchange device 4 is arranged in the heat exchange box 1, and the upper portion of the heat exchange box 1 is covered with a wave and mist preventing device 5. Burning heating device 2 produces the heat, the heat flows into to the flue gas house steward in, flue gas house steward rethread flue gas branch pipe evenly distributed to heat transfer bottom of the case portion, water to the bottom heats, and then gasify the liquid gas in heat transfer device 4, because constantly blowing in the water bath of high temperature flue gas, make the water of heat transfer case 1 inside constantly roll and the disturbance, the violent disturbance of top water with roll respectively can get into the unrestrained defogging device 5 that prevents that sets up the top three layer construction of a take the altitude, thereby can avoid the phenomenon of surge appearing, and then noise when reducing water and rolling, can also reduce the distance at the surface of water and heat transfer case 1 top, and then can be at the inside more water of filling of heat transfer case 1, because the volume of water is improved, thereby can place the heat transfer device 4 that the volume is bigger, can further improve the efficiency of gasification.

In this embodiment, in order to make the fog effectively liquefy, arrange waste gas to heat transfer case 1's outside, thereby will prevent unrestrained defogging device 5 and design into the three layer construction that the interval set up, including first unrestrained defogging board 501 of preventing, unrestrained defogging board 502 and the unrestrained defogging board 503 of third of second preventing, through first unrestrained defogging board 501 of preventing, the effect of unrestrained defogging board 502 of second preventing and third preventing, make the fog smoothly pass through and play certain fog liquefaction effect, the water bath is stayed to the greatest extent to the heat, waste gas discharges to heat transfer case 1's outside fast.

In this embodiment, in order to further enable the mist to be discharged evenly and quickly, the first wave-proof and mist-removing plate 501 is selected as a 200-mesh screen plate, the second wave-proof and mist-removing plate 502 is selected as a 400-mesh screen plate, the third wave-proof and mist-removing plate 503 is selected as a 800-mesh screen plate, and the mist passes through the screen plate with the gradually reduced aperture, so that the heat of the mist can be liquefied and then is retained in the water bath.

In this embodiment, in order to facilitate the discharge of the waste gas after the liquefaction of the mist to the outside of the heat exchange box 1, a chimney 6 is arranged at the top of the heat exchange box 1, and the mist can be collected and discharged through the chimney 6.

In this embodiment, 3 one ends of flue gas pipe are provided with and stretch into to the inside flue gas branch pipe device 7 of heat transfer case 1, and the steam that 3 flue gas pipes produced can carry to the inside tympanic bulla disturbance that produces of heat transfer case 1 through flue gas branch pipe device 7 fast to can carry out the even heating to water fast.

In actual work, the burning heating device 2 produces heat, the heat flows into in flue gas pipe 3, heat water fast through flue gas branch pipe device 7, and then liquid gas to among heat transfer device 4 heats and makes its gasification, because the water bath that constantly blows in of high temperature flue gas, make the water of heat transfer case 1 inside constantly roll and disturb, the violent disturbance of top water with roll and can get into one and prevent unrestrained defogging board 501 respectively, in second prevents unrestrained defogging board 502 and the unrestrained defogging board 503 of third, heat transfer case 1 of discharging at last, fog collects and locates to discharge to the outside at chimney 6, thereby can avoid the phenomenon of surge appearing, and then noise when reducing water and rolling, the heat loss has further been reduced simultaneously, the efficiency of gasification is improved.
