Embodiment Construction

[0029] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] Such as figure 1 As shown, the indirect heating thermal desorption treatment device for oily solid waste in the present invention includes a feed pretreatment unit 1, a feed metering and protection unit 2, an indirect heating and thermal desorption unit 3, a desorption steam separation and purification unit 5, a circulation Water treatment and oil collection unit 6 , slag post-treatment unit 4 , sewage purification unit 7 , nitrogen protection unit 8 and automatic control unit 9 .

[0031] Feed material pretreatment unit 1 is equipped with a feed stockyard for classified acceptance and storage of oily solid waste. Obvious sundries such as packaging bags are removed in the feed stockyard, and then the mixing and homogenization of various types of oil sludge is completed by turning and throwing machinery For the dispersing operation, the...

Abstract

The invention discloses an indirect heating and thermal desorption treatment device and method for oily solid waste. The device comprises an automatic control unit, a feeding pretreatment unit, a feeding metering and protecting unit and an indirect heating and thermal desorption unit, wherein the feeding pretreatment unit, the feeding metering and protecting unit and the indirect heating and thermal desorption unit are sequentially communicated with one another through an oily solid waste material conveying mode; a desorbed gas and oil gas outlet of the indirect heating and thermal desorption unit is connected with a desorbed gas separating and purifying unit; a discharge hole of the indirect heating and thermal desorption unit is connected with a muck post-treatment unit; the indirect heating and thermal desorption unit is composed of a heating cavity and a thermal desorption cavity; a heated part of the thermal desorption cavity is arranged in the heating cavity; and an internal space of the thermal desorption cavity and the internal space of the heating cavity are two cavities which are independently separated and are not communicated. The invention further discloses a method using device.

Description

technical field [0001] The invention relates to an indirect heating thermal desorption treatment device and method for oily solid waste, more specifically, a method and device for desorbing and separating petroleum hydrocarbons or organic pollutants from solid waste, and is mainly used in various Recycling and harmless treatment of oily solid waste such as oily sludge, oil-based drilling cuttings and oil-contaminated soil. Background technique [0002] In the process of oil field production, a large amount of oily sludge such as landing oil sludge, operational oil sludge, large tank bottom sludge and water treatment sludge will be produced every year; during the exploration and drilling of oil or gas wells, more and more oil production oil-based or Synthetic-based advanced drilling technology produces a large amount of oil-based drilling cuttings; due to illegal discharge or accidental leakage, a large amount of oil-polluted soil will be produced every year; in addition, oil...
