Problems solved by technology

[0004] At present, the feeding device for feeding oilfield waste into the heating chamber is mainly a belt or screw feeder, which occupies a large area and is not suitable for oilfield waste with a large degree of liquid state, and the conveying speed and volume are difficult to control. If the speed is fast, there will be too much material in the heating chamber, which will easily cause insufficient heating and incomplete treatment of the material; if the conveying speed is slow, it will be difficult to efficiently use the high-temperature flue gas generated by the burner, and the energy utilization efficiency will be low.

Embodiment 1

[0024] Such as figure 1 As shown, it includes a main pipe 1 and a plurality of branch pipes 2. The front ends of the branch pipes 2 are all connected to the rear end of the main pipe 1, and the rear ends of the branch pipes 2 are connected to the corresponding heating chamber 3. On the main pipe 1 A main mud pump 4 is installed, and the main mud pump 4 is a displacement pump, and branch valves 5 are installed on the branch pipes 2 .

[0025] When in use, first open the branch valve 5 on one branch pipe 2, and then close the branch valves 5 on the other branch pipes 2. The main mud pump 4 works to pump the material through the main pipe 1 to the corresponding branch pipe 2 and then into the Corresponding to the heating chamber 3.

[0026] After the main mud pump 4 runs for a set time T, close the opened branch valve 5, and then open the branch valve 5 on the next branch pipe 2, so that the material is pumped into the heating chamber 3 corresponding to the next branch pipe 2 ,...

Embodiment 2

[0029] Such as figure 2 As shown, it has the same structure as that of Embodiment 1, and the different technical feature is that: the branch pipe 2 is equipped with a branch regulating valve 6, and the branch regulating valve 6 is located on the front side of the branch valve 5, and the branch A calibration pipe 7 is installed on the pipes 2, and the front end of the calibration pipe 7 is connected to the branch pipe 2. The connection point between the calibration pipe 7 and the branch pipe 2 is located between the branch regulating valve 6 and the branch valve 5. A calibration valve 8 is installed.

[0030] When in use, close the branch valve 5 of each branch pipe 2, and open the branch regulating valve 6 and calibration valve 8 on each branch pipe 2, use the main mud pump 4 to transport the material through the main pipe 1 to each branch pipe 2, and Discharge from each calibration tube 7. After each calibration tube 7 starts to discharge the material, the amount of materi...

Embodiment 3

[0033] Such as image 3 As shown, it has the same structure as Embodiment 1, and the difference technical feature is that branch mud pumps 9 are installed on the branch pipes 2, and the branch mud pumps 9 are also displacement pumps, located at the side of the branch valve 5. front side.

[0034] The displacements of the branch mud pumps 9 are all the same, and are all smaller than the main mud pump 4 .

[0035] When in use, the main mud pump 4 transports the material to each branch pipe 2 through the main pipe 1, and then the branch mud pump 9 on each branch pipe 2 pumps the material into each heating chamber 3.

[0036] Since the branch mud pump 9 is a positive displacement pump, the amount of material delivered by each revolution or each stroke of its operation is constant. During the working process, the motor frequency of each branch mud pump 9 is maintained at the same value, and the displacement of the main mud pump 4 must be matched with the total intake of each bran...

Abstract

A feeding device for an oilfield waste treatment system, comprising a main pipe and a plurality of branch pipes, the front ends of the branch pipes are connected to the rear end of the main pipe, and the rear ends of the branch pipes are connected to corresponding heating chambers, A main mud pump is installed on the main pipe, and the main mud pump is a displacement pump, and branch valves are installed on the branch pipes. The feeding device used in the oilfield waste treatment system uses a volumetric pump for pumping, which can not only realize the transportation and distribution of materials with high fluidity, but also realize the metering of the feed, so that the materials sent into the heating chamber The moderate amount can not only ensure the complete material treatment, but also make the use of the heat energy generated by the burner more efficient and improve the treatment efficiency. Through the measurement of the calibration port and the adjustment of the branch regulating valve, the material can be fed into the heating chamber at a constant speed for a long time, so that the waste treatment operation is continuous and the work efficiency is further improved.

Description

technical field [0001] The invention relates to an oilfield waste treatment technology, in particular to a feeding device and a working method for the oilfield waste treatment system. Background technique [0002] With the increasing development of unconventional energy such as shale gas in the country, oilfield wastes such as waste oil-based mud and oily drilling cuttings continue to be produced and accumulated in large quantities. In oil and gas exploration, development and production, waste oil-based mud and oily drilling cuttings Improper disposal of oilfield waste, such as oilfield waste, will cause serious pollution of water resources and soil, and restrict development progress. [0003] The current processing equipment for oilfield waste treatment mainly sends oilfield waste into the heating chamber through the feeding device, and the heating chamber is placed in the combustion chamber. The air and the shell of the heating chamber perform convective heat exchange, in...
