Embodiment 1

[0031] The plant raw material used in this embodiment is corncob.

[0032] 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;

[0033] 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

[0040] The plant material used in this example is bamboo chips (about 40 cm long).

[0041] 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;

[0042] 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

[0048] 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.

[0049] 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;

[0050] 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, and in particular relates to an environment-friendly automobile tail gas absorption device. The environment-friendly automobile tail gas absorption device comprises a tail gas pipe, wherein a gas inlet and a gas outlet are formed in two ends of the tail gas pipe, respectively; the gas outlet is connected with a tail gas absorption box; an absorption liquid groove is formed in the bottom of the tail gas absorption box and is communicated with a liquid inlet which is formed inside the top of the tail gas absorption box; a purified gas outlet is formed in one side of the top of the tail gas absorption box; a first environment-friendly filter layer is arranged above the absorption liquid groove and comprises plant carbon plastic layers and sponge layers, which are arranged in a staggered manner; according to a specific arrangement mode, the plant carbon plastic layers are arranged on one side of the upper part of the first environment-friendly filter layer, the sponge layers are arranged on the other side of the upper part of the first environment-friendly filter layer, each sponge layer is arranged at the lower end of the corresponding plant carbon plastic layer, and another plant carbon plastic layer is arranged at the lower end of the corresponding sponge layer. The environment-friendly automobile tail gas absorption device has a flame-retardant effect, and can thoroughly absorb tail gas pollutants.

Description

technical field [0001] The invention relates to an exhaust gas absorbing device, in particular to an environment-friendly automobile exhaust 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 diox...
