Embodiment 1

[0034] The plant raw material used in this embodiment is corncob.

[0035] Put the plant raw material into the microwave vacuum tank, vacuumize until the vacuum degree is -0.02MPa, and then carry out microwave treatment, the microwave frequency is 300MHzMHz, and the microwave treatment time is 1min;

[0036] The plant raw materials obtained through pretreatment are dried, pre-carbonized, carbonized, calcined, and cooled in sequence. The temperature at each temperature measurement point is 150°C in drying area A, 275°C in pre-carbonization area B, and 450°C in carbonization area C. Observation during warming figure 1 The zone D shown is the temperature of different positions in the combustion zone. When the temperature of a certain place in the combustion zone, such as d2, is too low, open the small hole in that place, introduce air and burn it nearby, so as to raise the temperature in this place and control the bamboo to move down. The temperature of the combustion zone exper...

Embodiment 2

[0043] The plant material used in this example is bamboo chips (about 40 cm long).

[0044] Put the plant material into the microwave vacuum tank, vacuumize until the vacuum degree is -0.001MPa, and then carry out microwave treatment, the microwave frequency is 950MHz, and the microwave treatment time is 3min;

[0045] The plant raw materials obtained through pretreatment are dried, pre-carbonized, carbonized, calcined, and cooled in sequence. The temperature at each temperature measurement point is 150°C in drying area A, 275°C in pre-carbonization area B, and 450°C in carbonization area C. Observation during warming figure 1 The zone D shown is the temperature of different positions in the combustion zone. When the temperature of a certain place in the combustion zone, such as d2, is too low, open the small hole in that place, introduce air and burn it nearby, so as to raise the temperature in this place and control the bamboo to move down.

Embodiment 3

[0051] The plant raw material used in this embodiment is pine tree, and the pine tree is first cut after the skin impurities are removed, and the length is controlled to be no more than 15 cm.

[0052] Put the plant raw material into the microwave vacuum tank, vacuumize until the vacuum degree is -0.01MPa, and then carry out microwave treatment, the microwave frequency is 550MHz, and the microwave treatment time is 2min;

[0053] The pre-treated plant raw materials are dried, pre-carbonized, carbonized, calcined, and cooled in sequence. The temperature at each temperature measurement point is 180°C in the drying area A, 325°C in the pre-carbonization area B, and 530°C in the carbonization area C. Observation during warming figure 1 The zone D shown is the temperature of different positions in the combustion zone. When the temperature of a certain place in the combustion zone, such as d2, is too low, open the small hole in that place, introduce air and burn it nearby, so as to ...

Abstract

The invention relates to a tail gas absorption device, in particular to an antiflaming tail gas absorption device comprising a tail gas pipe. Two ends of the tail gas pipe are respectively provided with a gas inlet and a gas outlet, a tail gas absorption case is connected with the gas outlet, an absorption liquid groove is arranged on the bottom of the tail gas absorption case, the absorption liquid groove is communicated with a liquid inlet arranged in the top portion of the tail gas absorption case, one side of the top portion of the tail gas absorption case is provided with a purified gas outlet with hexagonal cross section, a first environmental protection filtering layer is arranged above the absorption liquid groove, one side of the purified gas outlet is provided with a second environmental protection filtering layer and a guide plate which are arranged at the upper end of the first environmental protection filtering layer, the first environmental protection filtering layer comprises plant carbon plastic and sponge arranged in intersection, one side of the upper portion of the first environmental protection filtering layer is a plant carbon plastic layer, the other side of the first environmental protection filtering layer is a sponge layer, and the lower end corresponding to the sponge layer is the plant carbon plastic layer. The tail gas absorption device has antiflaming property and can absorb tail gas pollutant completely.

Description

technical field [0001] The invention relates to a tail gas absorbing device, in particular to a flame-retardant and environment-friendly tail gas absorbing device. Background technique [0002] Automobile exhaust is the exhaust gas emitted by the engine. This gas emission not only smells weird, but also makes people dizzy and nauseated, which affects people's health. In the case of few vehicles, the self-purification ability of the atmosphere can still dissolve the toxins emitted by the cars. However, with the rapid increase in the number of cars, traffic congestion has become commonplace, and the advantages of convenience, comfort, and efficiency that cars should have are gradually offset by too many vehicles. "Car disaster" has been formed, and the resulting car exhaust is even more harmful. [0003] Scientific analysis shows that automobile exhaust contains hundreds of different compounds, among which pollutants include solid suspended particles, carbon monoxide, carbon...
