Description

Technical Field

[0001] This utility model relates to the technical field of natural gas energy conservation and emission reduction devices, specifically a natural gas user terminal energy conservation and emission reduction device. Background Technology

[0002] Currently, there are two main methods for saving energy in natural gas: one is to improve the structure of equipment to improve the combustion of natural gas, but this method is not universal due to the wide variety of equipment used for burning natural gas; the other is to add natural gas enhancers to achieve energy savings. However, most enhancers are oil-based, flammable, and explosive, making transportation and storage inconvenient. Some water-based enhancers are non-toxic, odorless, non-flammable, and non-explosive, but they are unstable emulsions that will precipitate over time, and commonly used dosing devices cannot meet the requirements of these water-based enhancers. In addition, changes in ambient temperature (sudden changes in temperature) can easily lead to incomplete combustion during natural gas transportation. Therefore, there is a need to develop a universal, easy-to-install, and quick-to-install energy-saving and emission-reduction device for natural gas users that can significantly improve the performance of natural gas, increase the air intake during combustion, ensure complete combustion of natural gas with oxygen in the air, reduce exhaust smoke emissions, and meet energy-saving and environmental protection requirements. Utility Model Content

[0003] The purpose of this utility model is to provide a natural gas user terminal energy-saving and emission-reduction device that is highly versatile, easy and quick to install, can significantly improve the performance of natural gas, and can also increase the amount of air intake during combustion, so that natural gas and oxygen in the air can be fully combusted, reducing the amount of exhaust gas and black smoke emissions, and meeting the requirements of energy saving and environmental protection.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a natural gas user terminal energy-saving and emission-reduction device, comprising a natural gas branch pipe installed on a natural gas main pipe, the natural gas branch pipe being connected to the user terminal, a magnetizer installed on the natural gas branch pipe, the magnetizer comprising a shell, two or more sets of annular magnetic blocks installed on the natural gas branch pipe inside the shell, the annular magnetic blocks being evenly divided into two semi-circular magnetic sheets, the N poles and S poles of the two semi-circular magnetic sheets being alternately arranged, the left and right ends of the shell being connected to a left end cap and a right end cap respectively by threads; the natural gas branch pipe at the outlet of the magnetizer is sequentially connected to a contraction pipe, a throat pipe and an expansion pipe, the throat pipe and the expansion pipe being connected by a first flange and a second flange, a nozzle body being installed between the first flange and the second flange, the nozzle body having a plurality of nozzles evenly arranged circumferentially, the second flange having an air hole, the nozzle inlet being connected to the atmosphere through the air hole, and the nozzle outlet extending into the throat pipe.

[0005] Furthermore, the distance between the opposite end faces of two adjacent sets of annular magnetic blocks is 5-12cm.

[0006] Furthermore, a shut-off valve is provided at the front end of the magnetizer, and a one-way valve is provided at the rear end of the magnetizer. The flow direction of the one-way valve is from the magnetizer to the contraction tube.

[0007] Furthermore, O-rings are provided between the end face of the first flange that contacts the nozzle body and the end face of the nozzle body that contacts the second flange.

[0008] The beneficial effects of this utility model are as follows: This utility model is installed on a natural gas branch pipe connected to the user terminal, making installation convenient and quick. It can adapt to different natural gas pipelines. The magnetic field generated by the magnetizer can magnetize the natural gas, adjust the molecular structure of the natural gas, and cause the substances in the natural gas to shift towards a stable state (such as shifting from an asymmetric structure to a symmetric structure), thereby improving the performance of the natural gas. At the same time, when a Venturi tube is set at the outlet of the magnetizer, the natural gas gas flow changes from coarse to fine as it flows from the contraction tube to the throat tube, accelerating the gas flow rate and creating a vacuum zone behind the Venturi tube outlet. This causes the surrounding air to be drawn into the throat tube through the air hole and nozzle, increasing the air intake and allowing the natural gas and oxygen in the air to burn completely at the user terminal, reducing the amount of exhaust gas and black smoke emissions and meeting energy-saving and environmental protection requirements.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-3 This utility model provides a technical solution: a natural gas user terminal energy-saving and emission-reduction device, including a natural gas branch pipe 2 installed on a natural gas main pipe 1, the natural gas branch pipe 2 being connected to the user terminal, a magnetizer 5 installed on the natural gas branch pipe 2, the magnetizer 5 including a shell 51, two or more sets of annular magnetic blocks 52 installed on the natural gas branch pipe 2 inside the shell 51, the annular magnetic blocks 52 being evenly divided into two semi-circular magnetic sheets 521, the N poles and S poles of the two semi-circular magnetic sheets 521 being alternately arranged, the left and right sides of the shell 51... The left end cap 53 and the right end cap 54 are connected by threads at both ends respectively; the natural gas branch pipe 2 at the outlet of the magnetizer 5 is connected in sequence to the contraction pipe 6, the throat pipe 7 and the expansion pipe 8. The throat pipe 7 and the expansion pipe 8 are connected by the first flange 10 and the second flange 11. A nozzle body 9 is provided between the first flange 10 and the second flange 11. Several nozzles 91 are evenly arranged circumferentially on the nozzle body 9. A gas hole 111 is provided on the second flange 11. The inlet of the nozzle 91 is connected to the atmosphere through the gas hole 111. The outlet of the nozzle 91 extends into the throat pipe 7.

[0015] The distance between the opposite end faces of two adjacent sets of annular magnetic blocks 52 is 5-12cm.

[0016] A shut-off valve 3 is installed at the front end of the magnetizer 5, and a one-way valve 4 is installed at the rear end of the magnetizer 5. The flow direction of the one-way valve 4 is from the magnetizer 5 to the contraction pipe 6. The one-way valve 4 can prevent natural gas from flowing back into the magnetizer 5 and the natural gas main pipe 1, thereby improving safety performance.

[0017] O-rings 12 are provided between the end face of the first flange 10 that contacts the nozzle body 9 and the end face of the nozzle body 9 that contacts the second flange 11.

[0018] When using this invention, the device is first installed on the natural gas branch pipe 2 connected to the user terminal. Installation is convenient and quick, and it can adapt to different natural gas pipelines. The magnetic field generated by the magnetizer 5 can magnetize the natural gas, adjust the molecular structure of the natural gas, and cause the substances in the natural gas to shift towards a stable state (such as shifting from an asymmetric structure to a symmetric structure), thereby improving the combustion performance of the natural gas. At the same time, when the venturi tube is set at the outlet of the magnetizer 5, the natural gas flows from the contraction pipe 6 to the throat pipe 7. The airflow changes from coarse to fine, and the gas flow rate increases. This creates a vacuum zone behind the outlet of the venturi tube, causing the surrounding air to be drawn into the throat pipe 7 through the air hole 111 and the nozzle 91. This increases the amount of air drawn in, allowing the natural gas and oxygen in the air to burn completely at the user terminal, reducing the amount of exhaust gas and black smoke emissions, and meeting the requirements of energy conservation and environmental protection.
