The more serious problem is that the high-temperature tail gas generated after the organic waste gas is combusted in the hearth comes out of the high-temperature heat exchanger at the front and then enters the low-temperature heat exchanger at the back, and the wind resistance is increased due to the turbulent flow formed at the front end of the low-temperature heat exchanger by the change of the tail gas flow channel. In addition, because the heat exchange tubes of the high-temperature heat exchanger are long, supports are required to be additionally arranged in the furnace body to support each heat exchange tube, so that the shell pass flow channels of the tube-in-tube heat exchanger are shielded by the supports to increase the wind resistance. In order to overcome the wind resistance in the two aspects, a waste gas conveying fan with higher pressure is needed, so that the operation energy consumption of the fan is increased, the pressure in the furnace is increased, and the gas in the furnace is easy to leak outwards. When waste gas is in the incineration equipment design, partial waste gas pyrolysis is insufficient and a hearth negative pressure mode is not adopted for avoiding the generation of airflow dead angles in a hearth, namely, the inner airflow of a furnace body can not be driven by the way of exhausting from the outlet end, and the waste gas can only be sent into the hearth from the inlet end through the pressure of a fan, so that positive pressure can be formed in the hearth.

In this embodiment, the heat exchange tube 4 may be a quartz glass tube or a ceramic tube.
In this embodiment, the bent section of the heat exchange tube 4 may be one or more sections.
In this embodiment, an exhaust gas inlet 21 is provided at the exhaust gas heat exchange area 2 and near the first sealing wall 5.
In this embodiment, the fresh air heat exchange area 3 is provided with a hot air outlet 32 near the first sealing wall 5, and the fresh air heat exchange area is provided with a fresh air inlet 31 near the second sealing wall 6.
The utility model discloses a casing is formed by the refractory material of inlayer, medial insulation material and outer metal material combination, and refractory material includes resistant firebrick or fire-resistant potsherd, and the interior part structure of casing can adopt extrusion moulding's cavity ceramic board.
The working principle is as follows:
the high-temperature chamber 1, the waste gas heat exchange area 2 and the fresh air heat exchange area 3 share a shell from left to right to form an integral body which can not be divided, and the heat exchange tube 4 passes through the first sealing wall 5 and the second sealing wall 6 to respectively pass through the waste gas heat exchange area 2 and the fresh air heat exchange area 3, so that a structure that the heat exchange tube 4 communicates the high-temperature chamber 1 with the outside is formed. The heat exchanger comprises the shell and the heat exchange tube which are of an integral structure, and the port butt joint between each part does not exist, so that the risk of leakage caused by poor interface sealing can be avoided.
The waste gas heat exchange area 2 and the fresh air heat exchange area 3 are both of a shell-and-tube heat exchanger structure, the waste gas heat exchange area 2 has the task of realizing heat exchange between high-temperature tail gas flowing out of a tube-pass flow channel and waste gas entering a shell-pass flow channel from a waste gas inlet 21, and the waste gas heat exchange area 2 can save energy sources supplemented by waste gas incineration after the temperature of the waste gas before incineration is increased. The task of the fresh air heat exchange area 3 is to further recover the heat of the tail gas in the rear-section tube pass flow channel, the external air entering from the fresh air inlet 31 passes through the shell pass flow channel of the fresh air heat exchange area 3 to exchange heat with the internal heat exchange tubes 4, and then flows out from the hot air outlet 32, the waste heat of the tail gas is fully utilized, the emission temperature of the tail gas is reduced, and the environment-friendly effect is achieved.
The first and second sealing walls 5 and 6 serve to isolate the corresponding regions from air leakage or cross-air.

However, the two sealing areas only limit the axial movement and the radial swing of the heat exchange tubes, and the problem of structural safety is not completely solved, because enough shell pass flow channel space needs to be reserved, and each heat exchange tube has a space, so that other heat exchange tubes except the heat exchange tube at the bottommost layer in the waste gas heat exchange area can be in a cantilever state, and the brittle heat exchange tubes such as ceramics or quartz glass are easily broken due to the overlarge length-diameter ratio of the cantilever.
The utility model discloses a heat exchange tube 4 of upper and lower adjacent correspondence forms cross structure, contacts each other from top to bottom by near the heat exchange tube 4 of high temperature chamber in waste gas heat exchange district, utilizes below heat exchange tube 4 to bear its top heat exchange tube 4, adopts this kind of structure can be under the condition that need not add other supports, through the mutual support between the heat exchange tube, lets the free end of heat exchange tube cantilever obtain the bearing and solved the cantilever force problem.
Because the cantilever part of the heat exchange tube is supported by the heat exchange tube in cross contact with the lower part of the cantilever part, and because gaps exist at the left side and the right side of the heat exchange tube, if the heat exchange tube is subjected to external force such as internal wind force and shaking in transportation, the heat exchange tube is easy to move in the radial direction to be separated from the support of the heat exchange tube at the lower part, so that the heat exchange tube returns to the cantilever state again to be damaged, and therefore, under the condition of no other fixing means, the heat exchange tube is fixed by adopting two sealing walls to avoid radial swinging of the heat exchange tube, which is particularly important.
