Example Embodiment

[0017] Example 1:

[0018] This embodiment provides a method such as figure 1 , 2 The umbrella-shaped liquid atomizer shown includes an inlet straight pipe body 1, a plurality of outlet elbow pipe bodies 2, the inlet straight pipe body 1 has one end open, and the other end is sealed, and the multiple outlet elbow pipe bodies 2 are The sealing end of the inlet straight pipe body 1 is uniformly arranged in the circumferential direction and formed into an umbrella shape. One end of each outlet elbow body 2 is connected with the inlet straight pipe body 1 and the other end is connected with an atomizing nozzle 3.

[0019] The liquid enters from the inlet straight pipe body 1, and passes through the outlet elbow body 2 and is sprayed by the atomizing nozzle 3 and atomized. Because the liquid is divided into multiple paths from the inlet straight pipe body 1, and the atomizing nozzle 3 has a small aperture, it forms a semicircle. Atomized spray.

Example Embodiment

[0020] Example 2:

[0021] On the basis of Embodiment 1, this embodiment provides an umbrella-shaped liquid atomizer, and the diameter of the atomizing nozzle 3 is 0.3 mm to 1.8 mm. There are 12 outlet elbow bodies 2.

[0022] The inlet straight pipe body 1 and the outlet elbow pipe body 2 are welded, and the outlet elbow pipe body 2 and the atomizing nozzle 3 are threadedly connected. To facilitate disassembly, cleaning, replacement and maintenance.

[0023] The inlet straight pipe body 1 and the outlet elbow pipe body 2 are both 304 stainless steel pipes. Temperature resistance 800℃, corrosion resistance, good processing performance and high toughness.

[0024] The atomizing nozzle 3 uses tungsten carbide YG8 material. The hard alloy tungsten carbide YG8 material has a heat treatment hardness of HRC92~95, and it has high erosion resistance.

Example Embodiment

[0025] Example 3:

[0026] On the basis of the foregoing embodiment, this embodiment provides the use of an umbrella-shaped liquid atomizer. The umbrella-shaped liquid atomizer is used in the combustion treatment process of fracturing flowback fluid to treat the fracturing flowback fluid. Atomize.

[0027] The fracturing flowback fluid is the fracturing flowback fluid in the blowdown tank. After the fracturing flowback fluid enters the umbrella-shaped liquid atomizer through a pipeline and a pump, it is directly sprayed onto the gas combustion flame of the acid discharge cylinder through the atomizing nozzle 3 combustion.

[0028] Umbrella type liquid atomizer is used to improve the combustion efficiency of fracturing flowback fluid, so that the fracturing flowback fluid in the blowdown tank will pass through the liquid atomizer to form a mist spray, thereby increasing the fracturing flowback fluid in the acid discharge cylinder Local combustion covers the contact area, as far as p...

Abstract

The invention provides an umbrella-shaped liquid atomizer. The umbrella-shaped liquid atomizer comprises an inlet straight pipe body and a plurality of outlet elbow pipe bodies, wherein one end of the inlet straight pipe body is opened and the other end of the inlet straight pipe body is sealed; the plurality of outlet elbow pipe bodies are uniformly arranged along the peripheral direction of the sealed end of the inlet straight pipe body to form an umbrella shape; one end of each outlet elbow pipe body is communicated with the inlet straight pipe body; and the other end of each outlet elbow pipe body is connected with an atomization nozzle. According to the umbrella-shaped liquid atomizer provided by the invention, fracturing flowback liquid in a blowoff tank forms a semicircular atomized spraying shape through the liquid atomizer, and atomization combustion is carried out at a gas combustion part of an acid discharging barrel; and the combustion efficiency is high and the combustion is clean and complete. The umbrella-shaped liquid atomizer is simple in structure and convenient to use; a problem that the fracturing flowback liquid in the current blowoff tank cannot be combusted is solved, and the circulating combustion efficiency of the fracturing flowback liquid is improved; and the pollution to the environment and injuries to personal safety are reduced, so that the combustion treatment time and the waiting cost are saved, and the umbrella-shaped liquid atomizer has high practicability and remarkable effect.

Description

technical field [0001] The invention belongs to the technical field of spraying and discharging fluid treatment after fracturing, and in particular relates to an umbrella-shaped liquid atomizer and its application. Background technique [0002] At present, after perforating and fracturing operations in low-permeability gas reservoirs in Changqing Oilfield, it is necessary to perform blowout and liquid discharge operations before testing for production. In the early stage of spraying and discharging fluid, almost all the fracturing fluid returned from the tubing was filtered by the settling tank and then directly entered the sewage tank. Since most of the fracturing fluid had oily spots, the liquid in the sewage tank Floating oil stains on the surface are likely to cause surface pollution or environmental pollution, and pose a serious threat to the safety of construction personnel. The current treatment measures are to ignite the gas at the acid discharge cylinder after the g...
