Problems solved by technology

This will lead to high temperature on the part of the electric heating plate close to the electric heating element, low temperature on the far part, uneven temperature field, easy to cause coking of the material, and the sludge treatment is not up to standard
In addition, the body of the electric heating element heats up quickly, but the speed of heat transfer on the electric heating plate is relatively slow
This will cause when the temperature of the electric heating plate reaches the process temperature, the temperature of the electric heating element will be much higher than the process setting value, which will easily cause damage to the electric heating element
In actual operation, intermittent heating is generally used to reserve time for heat transfer, the operation is relatively cumbersome and the temperature control is difficult

Embodiment 1

[0072] Such as figure 1 As shown, this embodiment provides a heating furnace, including a furnace body 1, a heating turntable 2 and a rotating shaft 3; the heating turntable 2 is arranged in the furnace body 1, and the rotating shaft 3 runs through the furnace body 1; The connection is used to drive the heating turntable 2 to rotate, and one end of the rotating shaft 3 is connected with the motor 4 through a gear set. Such as figure 2 , image 3 and Figure 4 As shown, the heating turntable 2 is provided with a medium channel 20 for inputting and outputting heating medium. In order to further improve the heating uniformity and thermal efficiency, the medium channel 20 is set in the form of a coil; in order to improve the utilization rate of heat, the medium channel 20 is provided with two layers of coils in each heating turntable 2, between the two layers of coils Connected through the connecting pipe 200; the rotating shaft 3 is provided with a hollow pipeline 30, and th...

Embodiment 2

[0086] Such as Figure 6 As shown, this embodiment provides a heating furnace, including a furnace body 1, a heating turntable 2 and a rotating shaft 3; the heating turntable 2 is arranged in the furnace body 1, and the rotating shaft 3 runs through the furnace body 1; The connection is used to drive the heating turntable 2 to rotate, and one end of the rotating shaft 3 is connected with the motor 4 through a gear set.

[0087] Such as Figure 6 and Figure 7 As shown, different from Embodiment 1, the heating turntable 2 is divided into two independent parts, the first heating turntable part 2-a and the second heating turntable part 2-b; the hollow pipeline 30 is divided into two independent parts part, the first hollow piping unit 30-a and the second hollow piping unit 30-b. The first heating turntable part 2-a cooperates with the first hollow pipeline unit 30-a to form a molten salt circulation channel, and the second heating turntable part 2-b cooperates with the second ...

Abstract

The invention provides a heating furnace, a heating system and a method for treating oily sludge by using the heating furnace and the heating system. The heating furnace comprises a furnace body, a heating turntable and a rotating shaft; wherein the heating turntable is arranged in the furnace body, and the rotating shaft penetrates through the furnace body; the rotating shaft is connected with the heating turntable and is used for driving the heating turntable to rotate; a medium channel for inputting and outputting a heating medium is arranged in the heating turntable; and a hollow pipeline is arranged in the rotating shaft, and is communicated with the feed port and the discharge port of the medium channel. Te heating system comprises the heating furnace and a molten salt heating device. The method for treating the oily sludge by using the heating system comprises the following steps: inputting the oily sludge into the furnace body, and heating the oily sludge by using the heating medium in the heating turntable. The heating furnace provided by the invention is uniform in heating.

Description

technical field [0001] The invention relates to the field of heating equipment, in particular to a heating furnace, a heating system and a method for treating oily sludge using the same. Background technique [0002] During oil and gas drilling, a large amount of oily sludge will be produced. It contains complex components such as oil, clay, sewage, and various chemical treatment agents. It has the characteristics of high oil content and many organic pollutants, and there is a major risk of environmental pollution. [0003] The treatment methods for oily sludge mainly include physical, biological and chemical methods. The chemical treatment methods of oily sludge mainly include incineration, chemical demulsification and separation, heat treatment and so on. The heat treatment method is to send the oily sludge into the heating furnace through the transportation device, and a stirring member is installed in the furnace, and the drilling cuttings in the furnace are heated by ...
