When the high-temperature waste heat gas drying machine works, high-temperature waste heat gas radially enters from one end of the drying machine main body 19 and enters a gas channel formed by the first annular partition plate 82 and the transverse partition plate 81 according to a certain rule, the flow area of the gas is reduced, the flow speed of the gas is increased, and therefore the heat exchange coefficient of a gas wall is improved. The waste heat flue gas inlet 11 is one side of a high-temperature outlet end of the oily sludge, and the countercurrent arrangement is favorable for gradient utilization of heat.
The oily sludge drying device provided by the invention uses the principle of a traditional indirect heating type rotary drum pyrolysis device as a reference, on the basis, axial flue gas feeding is changed into radial flue gas feeding, and a circular flue gas channel is divided into equal parts by a partition plate at will, so that the purposes of reducing the sectional area of the flue gas channel and increasing the flow rate and the heat exchange coefficient are achieved. The heating flue gas coming out from the fuel furnace of the oil-containing sludge pyrolysis general process firstly enters from one end of a roller loaded with the oil-containing sludge with higher temperature in the radial direction, the heating flue gas indirectly transfers heat with a main body of the roller containing the oil-containing sludge through the wall surface of the roller, and after the air flow reaches the other end of the roller, the air flow is discharged out through a flue gas outlet at the other end of the roller. The flue gas channel is composed of annular partition plates and transverse partition plates according to a certain rule, the flue gas flows to the transverse partition plates from the first annular partition plate around the circumference of the roller, changes to the opposite direction, enters the second annular partition plate channel, and so on.
The annular partition plate and the transverse partition plate are made of high-temperature-resistant (600-800 ℃) stainless steel alloy, and the surfaces of the annular partition plate and the transverse partition plate are coated with 5-8 mm of high-temperature-resistant heat-insulating coating. Annular baffle one side is installed on flue gas channel's fire-resistant insulating layer, and the opposite side keeps the narrow and small interval of 1 ~ 5mm with the gyration rotary drum barrel to keep the gas tightness of each passageway. The cross section of the flue gas channel chamber is adjusted according to the size of the scale of the rotary drum and the amount of the heated flue gas, so that the number of the partition plates or the channels is determined. The final temperature of the dried oil-containing sludge is designed to be about 200 ℃, the residual heat of high-temperature flue gas can be completely utilized, and the pyrolysis fuel cost saved every year is huge.
The working principle of the invention is as follows: oily sludge materials sequentially pass through a vibrating screen 2, a double-flap valve 3 and a screw pump 4 from an oily sludge hopper 1 to enter a rotary drum 6, are heated in the rotary drum, most of water and part of oil gas are evaporated, and finally are discharged through a discharge end 13 and a slag outlet 14 or enter the next step. The rotary drum 6 is in a dividing wall heating mode and is the core of the whole system, the rotary drum is provided with a base, a support 15 and a gear transmission device 16, the oily sludge runs through the inner drum, the waste heat flue gas used for heating runs through the outer drum, the waste heat flue gas inlet 11 is located at the high-temperature end of the material, and the waste heat flue gas outlet 5 is located at the low-temperature end of the material. The rotary drum 6 is internally provided with an inner retainer ring 9 for increasing the retention time of moisture in the materials, the smoke channel is composed of a transverse partition plate 81, a first annular partition plate 82 and a second annular partition plate 83 according to a certain rule, smoke flows to the transverse partition plate from the first annular partition plate around the circumference of the drum, changes to the opposite direction and enters a second annular partition plate channel, and the like. On the basis of the traditional indirect heating type rotary drum, the axial flue gas is changed into the radial flue gas, and the circular flue gas channel is divided into equal parts by the partition plate at will, so that the aims of reducing the sectional area of the flue gas channel and increasing the flow velocity and the heat exchange coefficient are fulfilled.
Example 1
Taking the example of processing 200kg/h of refined three-sludge, the water content of the material is 85%, the oil content is 5%, the solid content is 10%, and the operation lasts 7000 hours per year. If a traditional partition wall heating type rotary drum is adopted, the design effective length of the rotary drum is 3.712m, the outer diameter of the rotary drum is 0.464m, and the original flue height is 0.1 m.
The original flue is now divided into annular flues of 0.3m width, arranged in the structural manner described in the present invention. Under the original condition, the flow velocity of the flue gas is calculated to be 2.05m/s, the Reynolds number is 2193 (being laminar flow), and the heat exchange coefficient of the flue gas and the outer wall of the rotary drum is 9.41W/(m2 ∙ K). After the structure of the invention is adopted, the flow velocity of the flue gas is 12.12m/s, the Reynolds number is 12950 (which is turbulent flow), the heat exchange coefficient of the flue gas and the outer wall of the rotary drum is 31.95W/(m2 ∙ K), and the increase amplitude is more than 3 times.
By adopting the drier of the invention, the oily sludge material is preheated to 200 ℃ so that the great part of water in the oily sludge material is evaporated, and the required total heat is about 134.74 KW. Because the partial heat is all waste heat resources, the natural gas cost is saved by about 31 ten thousand yuan each year, the treatment cost is reduced by about 221 yuan/ton compared with oil-containing sludge ton, and the economic benefit is very obvious.

(2) The main body of the drier adopts a special airflow organization mode, changes the traditional axial flue gas feeding into the radial flue gas feeding, and utilizes the annular partition plate to arbitrarily divide the heating flue gas channel into equal parts, so that the flow area is reduced, the flow speed of the flue gas is increased, the flue gas is changed into a turbulent flow state from the original laminar flow state under the condition of keeping the original flow rate of the flue gas unchanged, and finally the heat exchange efficiency is improved as the heat exchange coefficient of the gas wall is greatly increased. In addition, the flue gas and the materials are arranged in a countercurrent mode, so that the waste heat of the flue gas can be utilized in a gradient mode.
