Figure 1 to Figure 2 , the process of the microwave enhanced rotary kiln oily sludge treatment system provided by the embodiment of the present invention is described in detail.

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0036] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0037] The embodiment of the present invention provides a microwave enhanced rotary kiln oily sludge treatment system method, which is applied to an oily sludge treatment device with a microwave source. Figure 1 , the steps included in the control system are introduced in detail.

[0038] Step 101: Obtain the amount of waste oil sludge to be treated and the rotation speed of the kiln body.

[0039] In the embodiments of the present invention, the waste oil sludge is mostly generated during the oil field production process, that is, the sludge generated during the extraction, storage, collection and transportation, and processing of crude oil.

[0040] Exemplarily, a sensor is provided on the kiln body of the oily sludge treatment device with a microwave source to detect the rotation speed of the kiln body; further, the amount of the oily sludge added to the kiln body is determined based on a feed hopper at the kiln head connection of the kiln body.

[0041] Step 102: Determine the power of the first microwave source based on the amount of the waste oil sludge and the rotation speed.

[0042] In the embodiment of the present invention, the controller receives data sent by the sensor, determines the first microwave power of the microwave source to be used based on the amount of dirty oil sludge and the rotation speed, and uses the microwaves of the first power to pyrolyze the dirty oil sludge in the kiln body.

[0043] Step 103: Processing the waste oil sludge based on the first microwave source power.

[0044] In the embodiment of the present invention, step 103 processes the waste oil sludge based on the power of the first microwave source, and also includes the following methods:

[0045] Method 1: obtaining the temperature of the kiln body; adjusting the power of the first microwave source based on the temperature to obtain a second power; and treating the waste oil sludge based on the second power.

[0046] In the embodiment of the present invention, the controller is electrically connected to the sensor, and receives temperature data and microwave source power data acquired by the sensor in real time. Here, the controller determines whether the current temperature in the kiln body is within the preset temperature range based on the acquired temperature. If it exceeds the preset temperature range, the microwave source power is reduced, thereby effectively protecting the kiln body and improving the safety performance of the system. Correspondingly, if the controller determines that the current temperature is within the preset temperature range, the dirty oil sludge in the kiln body is processed based on the current microwave power.

[0047] Method 2: detecting the exhaust gas concentration at the exhaust port; determining the relationship between the exhaust gas concentration and a preset concentration to obtain a judgment result; adjusting the second power based on the judgment result to obtain a target power.

[0048] In an embodiment of the present invention, the controller is also used to detect the concentration of the exhaust gas at the outlet, and then compare the detected exhaust gas concentration with the preset concentration, so as to determine whether the treatment result meets the standard based on the concentration of the exhaust gas at the outlet. If it does not meet the standard, the gas is again introduced into the kiln body through a connected pipe, and the power of the microwave source is adjusted to obtain the target power, thereby treating the dirty oily sludge more energy-efficiently and effectively.

[0049] Specifically, the second power is adjusted based on the judgment result to obtain the target power, and then the method further includes: determining a corresponding control strategy based on the rotation speed of the kiln body and the target power; and processing the dirty oil sludge based on the control strategy.

[0050] In the embodiment of the present invention, the control strategy refers to determining the optimal parameters of the control system for processing a certain amount of oily sludge at low energy consumption and high efficiency according to the rotation speed of the kiln body and the determined target power. In this way, after a certain amount of oily sludge is placed in the kiln body, the oily sludge is processed according to the determined optimal parameters, thereby achieving efficient processing of the oily sludge.

[0051] The present invention provides a microwave-enhanced rotary kiln oily sludge treatment system, comprising: obtaining the amount of oily sludge to be treated and the rotation speed of the kiln body; determining the power of a first microwave source based on the amount of oily sludge and the rotation speed; and treating the oily sludge based on the power of the first microwave source. In other words, the oily sludge treatment method provided by the present invention has high efficiency in treating oily sludge, a more intelligent system, and wide practicability.

The specific implementation method and technical effect are similar and will not be repeated here.
