Description
Technical Field
The application relates to a pollute oven of soil pyrolysis or burning furnace belongs to the environmental protection field of purifying, especially relates to with the flue gas treatment device of soil pyrolysis or burning furnace.
Background
When the soil polluted by organic matters is subjected to pyrolysis or incineration treatment, the smoke is easy to generate carbon deposition on the furnace wall. Not only reduces the effective volume, but also is easy to block, and influences the treatment efficiency. Carbon deposition is inconvenient to check, the carbon deposition generation degree is often estimated by adopting CO2 and O2 sensors, the reliability is poor, chemicals are mostly adopted for cleaning, and the cleaning process is complex.
Disclosure of Invention
The purpose (technical problem to be solved) of the present application is: the furnace wall of the polluted soil pyrolysis or incinerator is provided, the structure of the furnace wall can reach 1, no chemical is used, and the deposited carbon on the furnace wall can be removed easily and instantly; 2. the carbon deposition part can be judged only by external visual observation or light irradiation; 3. selectively cleaning only the part with the carbon deposit, and not relating to other parts; 4. inducing the formation of carbon deposit.
The furnace wall of the polluted soil pyrolysis or incinerator adopts heat insulation materials such as aluminum silicate heat insulation cotton and the like as the furnace wall, small holes are uniformly and densely formed in the furnace wall, a glass tear drop finished product (tadpole-shaped glass tear drops formed by naturally dropping molten glass into ice water under the gravity) penetrates through the small holes, the head of the glass tear drops is close to the inner side of the furnace wall, the tail of the glass tear drops penetrates through the small holes and is exposed out of the outer side of the furnace wall, and the outer side of the furnace wall is fixed by a rubber ring and an iron wire.
The glass tear drop is a tadpole-shaped tear drop formed by naturally dropping molten glass into ice water by means of gravity, is more hard than common glass, can not be broken under the pressure of 8 tons, however, if pressure or torsion is applied to the tail of the glass tear drop, the whole glass tear drop can be instantaneously burst, splashed and completely crushed.
The furnace wall device has the characteristics that the heat conduction of glass is faster than that of aluminum silicate heat-insulating cotton, so that the surface temperature of the glass is lower than that of the inner surface of the furnace wall, the smoke is cooled on the surface of the glass tear drop, and carbon deposition is generated on the surface of the glass tear drop. Because the glass is transparent, the carbon deposition part can be judged only by visual inspection from the outside or illumination by lamplight. At the part with carbon deposit, pressure or torsion is applied to the tail of the glass tear drop from the outside, the glass tear drop can be instantly crushed, and the glass tear drop with the carbon deposit falls back to the furnace bottom for pyrolysis or incineration. The shattered glass tear drops are easily reinstalled. The device can remove the carbon deposit on the furnace wall in a short time simply and easily without chemicals.
Description of the drawings:
FIG. 1 is a view of the walls of a contaminated soil pyrolysis or incineration furnace according to the present application.
The implementation mode is as follows: the sample is the soil polluted by the diesel oil storage tank, aluminum silicate heat-insulating cotton with the thickness of 2 cm is used as a furnace wall, the inner diameter is 20 cm, small holes (distributed on the middle part and the upper part of the furnace wall) are uniformly and densely formed in the furnace wall by using a drilling machine, DN is 3 mm, and the distance between the centers of the small holes is 1 cm. Melting glass by using an alcohol lamp, naturally dropping the glass into ice water at 0 ℃ under the gravity during melting to form tadpole-shaped glass tear drops, selecting a glass tear drop with the head part diameter of about 1 cm, installing the glass tear drop on a small hole at the left side of a furnace wall, enabling the head part to be close to the inner side of the furnace wall, enabling the tail part to extend out of the outer side, and fixing the outer side by using a rubber ring and an iron wire. As a control, aluminum silicate insulation wool was cut into similar shapes (head diameter about 1 cm with DN 3 mm tail) and mounted over a small hole on the right side of the furnace wall. 5 cm thick aluminum silicate heat preservation cotton is paved at the bottom of the furnace to be used as the furnace bottom, an electric heating rod (introduced from a drill hole at the bottom of the furnace wall) is adopted to heat the polluted soil of the oil storage tank (introduced into a stirrer from a drill hole at the top), and the temperature of the soil is about 250 ℃. And 5 cm-thick aluminum silicate heat-insulating cotton is paved at the top of the furnace body to be used as a cover, air is introduced without power from the bottom (drilled holes) of the furnace wall (natural ventilation), and is discharged without power from the top (drilled holes). The heating was carried out for 3 days, 16 hours a day, during which time the contaminated soil of the storage tank was replaced with new one every 10 minutes. After 3 days, the furnace is irradiated from the outside by lamplight, most of the glass tear drops are seen to be opaque, and the furnace wall is disassembled, so that most of the glass tear drops and most of the aluminum silicate heat-preservation cotton balls used as the contrast are seen to be attached with carbon deposition. The tail of these glass tears was grasped with a pincer and crushed with a little effort. When the glass tear drops and the aluminum silicate heat-insulating cotton balls used as the reference are all removed, the inner surface of the furnace wall (the position of the gap which cannot be covered by the projection of the ball body) where the glass tear drops are located is basically free of carbon deposition, and the inner surface of the furnace wall (the position of the gap which cannot be covered by the projection of the ball body) where the glass tear drops are located mostly generates carbon deposition.
