Description

Technical Field

[0001] This utility model relates to the technical field of gas field water evaporator equipment, specifically to an evaporator structure with circulation for gas field water treatment. Background Technology

[0002] Gas field water is formation water extracted along with natural gas during the gas field extraction process. A certain amount of water originally exists in the formation where the gas field is located. This water and natural gas were stored together in the pores and fissures of the underground rocks during geological history. Natural gas is usually above the formation water, forming a gas-water interface. During the gas field development process, as natural gas is extracted, the formation water is displaced into the wellbore along with the natural gas due to the decrease in formation pressure, and then extracted to the surface, thus forming gas field water. In addition, in order to maintain the extraction pressure of the gas field, water injection and other production enhancement measures are sometimes carried out. This injected water may also be carried out along with the extraction of natural gas, increasing the production of gas field water.

[0003] In existing technologies, produced water from gas fields often contains abundant salt resources, such as sodium chloride and potassium chloride. During the process of treating produced water, evaporators can concentrate and crystallize salt substances, which facilitates subsequent salt recovery and utilization, and realizes comprehensive utilization of resources. However, during use, the water vapor discharged from the evaporator is directly discharged into nature after condensation, which requires a lot of condensate to cool the water vapor. In addition, there may be heat loss in the outer shell of the evaporator during operation, which increases heat consumption.

[0004] Therefore, an evaporator structure with circulation for gas field water treatment is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a circulating evaporator structure for gas field water treatment, which solves the technical problems of water vapor discharged from the evaporator being directly discharged into nature after condensation, which requires a large amount of condensate to cool the water vapor, and the possibility of heat loss from the outer shell of the evaporator during operation, which increases heat consumption. This invention achieves the purpose of recycling and heat preservation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an evaporator structure with circulation for gas field water treatment, including a support platform, an evaporator fixedly installed on one side of the top of the support platform, an inlet pipe connected to the outer wall of the evaporator, a waste discharge pipe connected to the bottom of the evaporator, a steam pipe connected to the top of the evaporator, a recycling component provided on the top of the support platform, and a heat insulation component provided on the surface of the evaporator.

[0007] Preferably, the recycling component specifically includes: a support frame, which is fixedly installed at equal intervals on the top of the support platform; a condenser, which is fixedly installed on the top of the support frame; a cooling bend, which is fixedly installed on the bottom of the inner wall of the condenser; a cold liquid tank, which is fixedly installed on the other side of the top of the support platform; a circulation pump, which is fixedly installed on the top of the cold liquid tank; and a return pipe, which is connected to the top of the condenser.

A motor is also fixedly installed at the output end of the motor, and a magnetic coupler is fixedly installed at the output end of the motor. Through the cooling curved pipe and connecting pipe structure, the steam generated by the evaporator is introduced into the cooling curved pipe in the condensing tank for cooling and condensation, converting the steam into liquid water. Then, it returns to the cold liquid tank through another connecting pipe, realizing the recovery and reuse of steam, improving the utilization rate of water resources, and reducing water waste in the gas field water treatment process. The circulating pump circulates the coolant in the cold liquid tank through liquid delivery pipe one and liquid delivery pipe two, and circulates it through the return pipe. The coolant in the condensing tank... The circulating flow between the coolant and the cold liquid tank continuously provides cooling capacity to the cooling bend, ensuring steam condensation and maintaining the uniformity of coolant temperature within the tank. The chiller cools the coolant in the tank via a cooling plate, precisely controlling its temperature and providing a stable low-temperature environment for steam condensation, thus improving condensation efficiency. The structure within the cold liquid tank, consisting of a rotating rod, mixing plate, magnetic coupler one, and magnetic coupler two, is driven by a motor. The rotating rod drives the mixing plate to rotate, stirring and mixing the coolant in the tank, resulting in a more uniform temperature and composition, preventing localized overheating or underheating, and achieving a circulation effect.

The first and second arc plates are connected and fixed through the first and second connecting plates, the recess, and the knob structure. During installation, simply place the arc plate on the outer wall of the liquid inlet pipe and the second arc plate on the outer wall of the evaporator. Then, screw the screw into the threaded hole of the recess using the knob to achieve quick installation of the insulation component. The vacuum insulation plate has extremely low thermal conductivity, which can effectively prevent heat loss from the evaporator and reduce energy consumption. Its inner side is in close contact with the outer wall of the evaporator, which can minimize the heat transfer to the outside through conduction and convection, providing a good insulation environment for the evaporator and improving the thermal efficiency of the evaporator, thereby achieving the insulation effect.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] Example 1:

[0026] The existing evaporator design, where water vapor is directly discharged into the environment after condensation, requires a significant amount of condensate to cool the vapor. Furthermore, heat loss from the evaporator's outer shell during operation increases heat consumption. This invention provides a preferred embodiment of a circulating evaporator structure for gas field water treatment, for example... Figure 1-5 As shown: A circulating evaporator structure for gas field water treatment includes a support platform 1, an evaporator 2 fixedly installed on one side of the top of the support platform 1, an inlet pipe 3 connected to the outer wall of the evaporator 2, a waste discharge pipe 4 connected to the bottom of the evaporator 2, a steam pipe 5 connected to the top of the evaporator 2, a recycling component 6 provided on the top of the support platform 1, and a heat insulation component 7 provided on the surface of the evaporator 2.

[0027] The recycling component 6 specifically includes: a bracket 611, which is fixedly installed at equal intervals on the top of the bracket platform 1; a condenser 612, which is fixedly installed on the top of the bracket 611; a cooling bend 613, which is fixedly installed on the bottom of the inner wall of the condenser 612; a coolant tank 614, which is fixedly installed on the other side of the top of the bracket platform 1; a circulation pump 616, which is fixedly installed on the top of the coolant tank 614; and a return pipe 619, which is connected to the top of the condenser 612.

[0028] The two ends of the cooling bend 613 are connected to the connecting pipe 615. The other end of the connecting pipe 615 is connected to one side of the inner wall of the condenser 612 and extends to the top of the steam pipe 5. The other end of the other connecting pipe 615 is connected to the other side of the inner wall of the condenser 612 and one side of the cold liquid tank 614 and extends into the interior of the cold liquid tank 614.

[0029] One side of the circulating pump 616 is connected to a liquid delivery pipe 617. The other end of the liquid delivery pipe 617 is connected to the other side of the condenser 612 and extends into the interior of the condenser 612. The other side of the circulating pump 616 is connected to a liquid delivery pipe 618. The other end of the liquid delivery pipe 618 is connected to the top of the cold liquid tank 614 and extends into the interior of the cold liquid tank 614. The other end of the return pipe 619 is connected to the top of the cold liquid tank 614 and extends into the interior of the cold liquid tank 614.

[0030] The front and back of the coolant tank 614 have holes. A cooling plate 6111 is fixedly installed between the inner walls of the holes. A cooler 6112 is fixedly installed on one side of the cooling plate 6111. A perforated concave plate 6113 is fixedly installed on one side of the inner wall of the coolant tank 614. A rotating rod 6114 is rotatably connected to the inner wall of the perforated concave plate 6113. A mixing plate 6115 is fixedly connected to the outer circumference of the rotating rod 6114 at equal intervals. A magnetic coupler 6116 is fixedly installed at one end of the rotating rod 6114.

[0031] A curved plate 6117 is fixedly installed on the other side of the coolant tank 614. A motor 6118 is fixedly installed on the surface of the curved plate 6117. A motor 6118 is fixedly installed at the output end of the motor 6118. A magnetic coupler 6119 is fixedly installed at the output end of the motor 6118.

[0032] In this example, cyclic condensation can be achieved by setting up the recycling component 6. The circulation pump 616 is started to work, and cold water is drawn from the condensation tank 612 through the second liquid delivery pipe 618 and enters the condensation tank 612 through the first liquid delivery pipe 617. After the condensation tank 612 is filled with cold water, it enters the cold liquid tank 614 through the return liquid pipe 619. Steam enters the cooling bend 613 through the steam pipe 5 and the connecting pipe 615. The cold water refrigerates the steam through the cooling bend 613, turning the steam into liquid water. The cold water enters the cold liquid tank 614 through another connecting pipe 615 for recycling, thereby achieving the effect of recycling.

[0033] Example 2:

[0034] Based on Embodiment 1, a preferred embodiment of the gas field water treatment evaporator structure with circulation provided by this utility model is, for example... Figure 1-5 As shown: The heat insulation component 7 specifically includes: Arc plate one 711, sleeved on the outer wall of the liquid inlet pipe 3; Arc plate two 712, disposed on the outer wall of the evaporator 2; Vacuum insulation plate 713, respectively fixedly installed on the inner side of arc plate one 711 and the inner side of arc plate two 712; Connecting plate one 714, circumferentially fixedly installed on the outer side of arc plate one 711; Connecting plate two 715, circumferentially fixedly installed on the outer side of arc plate two 712; Recessed block 716, equidistantly fixedly installed on the outer side of connecting plate one 714; Knob 717, equidistantly disposed on the outer side of connecting plate two 715.

[0035] The inner side of the vacuum insulation plate 713 is in contact with the outer wall of the evaporator 2. A threaded hole is provided on one side of the recess 716. A screw 718 is fixedly installed on one side of the knob 717. The other end of the screw 718 moves through the outer side of the connecting plate 2 715 and the inner side of the connecting plate 1 714 and extends to the inner wall of the threaded hole for threaded connection.

[0036] In this example, by setting up the heat insulation component 7, the heat dissipation of the evaporator 2 can be reduced. The vacuum insulation plate 713 can effectively prevent the heat loss inside the evaporator 2, reduce energy consumption, and minimize the transfer of heat to the outside, thereby achieving the effect of heat preservation.

[0037] Working principle: First, when steam needs to be circulated and condensed, the evaporator 2 generates steam, which enters the cooling bend 613 through the steam pipe 5 and connecting pipe 615. The circulation pump 616 is started, drawing cold water from the condenser 612 through the second liquid delivery pipe 618. The cold water then enters the condenser 612 through the second liquid delivery pipe 618 and the first liquid delivery pipe 617. After the condenser 612 is filled with cold water, it enters the cold liquid tank 614 through the return liquid pipe 619 for recovery, thus circulating the cold water in the condenser 612. The cold water in the condenser 612 cools the steam through the cooling bend 613, exchanging heat with the steam and converting it into liquid water. The condensed liquid water then enters the cold liquid tank 614 through another connecting pipe 615 for recovery. The refrigerator 6112 is then started to cool the water in the cold liquid tank 614 through the cooling plate 6111. The liquid is cooled, and at the same time, the motor 6118 is started to drive the magnetic coupler 6119 to rotate, which in turn drives the magnetic coupler 6116, the rotating rod 6114, and the mixing plate 6115 to rotate, so as to evenly mix the cold water inside and make the temperature uniform. When it is necessary to keep the evaporator 2 warm, heat loss can be reduced. The vacuum insulation plate 713 can effectively prevent the heat loss inside the evaporator 2, reduce energy consumption, and minimize the heat transfer to the outside. The vacuum insulation plate 713 is a heat insulation material composed of core material and high gas barrier composite film. When disassembling, rotating the knob 717 drives the screw 718 to rotate. The screw 718 separates from the threaded hole in the concave block 716, so the arc plate 711 and the arc plate 712 can be disassembled and separated, which facilitates the maintenance of the evaporator 2, thereby achieving the functions of recycling and heat preservation.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
