Abstract

The utility model discloses a tube furnace waste heat utilization device which comprises a tube furnace (1); a chimney of the tube furnace (1) is internally provided with a flue gas channel (2) communicated with a hearth; a ring-shaped cavity (3) provided with an opening on the top is formed between the flue gas channel (2) and the inner wall of the chimney; and the bottom of the ring-shaped cavity (3) is connected with a gas inlet of the tube furnace (1) by a gas guide pipe (4) and a draught fan (5). The tube furnace used in the process of processing coal tar is reformed, so that the flue gas waste heat in the furnace can be utilized by the reformed tube furnace, and the heat loss can be reduced; meanwhile, after heat exchange, the air with the temperature of 200-250 DEG C enters the tube furnace to be taken as combustion-supporting air, so that the consumption of fuel can be reduced, and the production cost is lowered.

Description

A kind of tube furnace residual heat using device

Technical field

The utility model relate to a kind of in the coal tar process afterheat utilization device, be specially a kind of tube furnace residual heat using device.

Background technology

Before the transformation; The combustion air source of tube furnace burning is to lean on the draft of tube furnace self to provide; The size of its air quantity leans on base burning device throttle opening size and chimney turnover panel aperture size to regulate; About 650 ℃ the high-temperature flue gas that its burning produces becomes the flue gas about 350 ℃ after tube furnace radiant section, convection section heat exchange, flue gas directly is disposed in the atmosphere through chimney, causes the waste of energy.

The utility model content

The utility model purpose: the purpose of the utility model is the deficiency to prior art, and a kind of tube furnace residual heat using device is provided.

Technical scheme: the described tube furnace residual heat using device of the utility model; Comprise tube furnace; The inner exhaust gases passes of the chimney of said tube furnace for communicating with burner hearth; Form the cavity of open-topped annular between said exhaust gases passes and the inner wall of stack, the bottom of said annular housing is connected with the air inlet of tube furnace through wireway, air-introduced machine.

Said exhaust gases passes is to be arranged on inner ￠ 800 steel pipes of chimney.

The utility model compared with prior art, its beneficial effect is: the utility model has been transformed used tube furnace in the coal tar processing, makes improved tube furnace utilize fume afterheat in the stove, has reduced thermal loss; 200～250 ℃ air entering tube furnace is interior as combustion air after the heat exchange simultaneously, reduces the consumption of fuel, reduces production costs.

Fig. 1 is the utility model structural representation.

The specific embodiment

Be elaborated in the face of the utility model technical scheme down, but the protection domain of the utility model is not limited to said embodiment.

Embodiment 1:

As shown in Figure 1; The utility model discloses said a kind of tube furnace residual heat using device; Comprise tube furnace 1; The steel pipe that is placed with a ￠ 800 in the chimney inside of said tube furnace 1 forms the cavity 3 of open-topped annular as exhaust gases passes 2 between said exhaust gases passes 2 and the inner wall of stack, the bottom of said annular housing 3 is connected with the burner hearth air inlet of tube furnace 1 through wireway 4, air-introduced machine 5.

Its operation principle is: the steel pipe of putting a ￠ 800 in tar workshop section tube furnace chimney inside; Air is the flue gas heat exchange with about 350 ℃ from entering back between the steel pipe interlayer of chimney and ￠ 800, and 200～250 ℃ air is introduced in the tube furnace burner hearth as combustion air by air-introduced machine after the heat exchange.

As stated, although represented and explained the utility model that with reference to specific preferred embodiment it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the utility model that does not break away from the accompanying claims definition, can make various variations in form with on the details to it.
