Embodiment Construction

[0029] The invention is mainly used for the drying treatment of industrial liquid waste, petroleum and chemical residual liquid sludge. By continuously maintaining the heat exchange efficiency between the treated object and the drying treatment device, the liquid sludge is carried out in a high temperature manner. Harmless or reduction treatment.

[0030] The structure and principle of the industrial liquid sludge drying treatment device in the embodiment of the present invention are as follows: Figure 1 to Figure 10 shown.

[0031] Such as figure 1 , figure 2 and Figure 7 to Figure 9 As shown, the heating tank of the industrial liquid sludge drying treatment device has a horizontal cylindrical tank body 100, and the outer shell of the tank body 100 is a double-layer structure, including an outer wall 1 and an inner wall 3, and between the outer wall 1 and the inner wall 3 It is the heating interlayer 2, and the interior of the heating interlayer 2 passes through high-t...

Abstract

The invention discloses an industrial liquid-containing sludge drying treatment device which comprises a heating tank, wherein the heating tank comprises a cylindrical tank body and a rotor; the rotor comprises at least one scraper plate group; the scraper plate group comprises a complex number of scraper plates which are distributed in the circumferential direction of the rotor; the tank body comprises a wet sludge inlet and a dry sludge outlet; a radial gap is formed between the scraper plate and the inner wall of the tank body; the complex number of scraper plates of one same scraper plate group are different in radial length; the radial gaps between the complex number of scraper plates and the inner wall of the tank body are gradually increased in the positive direction along which the rotor rotates. By adopting the device, water and oil in oily sludge can be separated, the oil content of the left residue is less than 1 percent, the water content is less than 5 percent, no pollution can be caused to the environment, and harmless treatment on the liquid-containing sludge is achieved.

Description

[technical field] [0001] The invention relates to industrial liquid sludge treatment, in particular to an industrial liquid sludge drying treatment device. [Background technique] [0002] In the field of environmental protection, industrial liquid wastes, petroleum and chemical residual liquid sludge are mostly treated by extrusion, centrifugation, concentration, filtration, and biodegradation to reduce the liquid content of these treated materials. There are not many ways to thoroughly dry the treated matter, or even to treat it with high-temperature harmless reduction. The main method is to treat it through the above-mentioned method and then incinerate it, but at the same time, toxic fumes are produced and pollute the atmospheric environment. [0003] Chinese invention application 201210425876.1 discloses a sludge thin-layer drying equipment, which includes a cylindrical heating chamber and a rotor with a scraper inside. One end of the cylindrical heating chamber is equip...
