Description

Technical Field

[0001] The utility model relates to the technical field of gas heating, in particular to a gas heating pipeline system. Background Art

[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] Gas is often used as a heat medium for heating in high-temperature air combustion experiments and simulations of engine waste heat. For example, in high-temperature air combustion experiments, heating the gas to a suitable temperature helps improve combustion efficiency and reduce nitrogen oxide production. Therefore, a reasonable heating device can ensure the stability and accuracy of the experimental results.

[0004] Existing gas heating devices mostly heat the gas in the pipeline through heaters and other heating equipment, but lack monitoring of the gas temperature and flow rate during the gas heating process. There is a risk that the heated gas cannot meet the experimental requirements, thereby affecting the stability and accuracy of the experiment.

[0005] Utility model patent application number 201621133993.0 discloses a gas heating system that utilizes a cascaded heating system consisting of at least two heat collectors connected to at least three stages of heat exchangers. This system improves thermal efficiency by providing greater resistance to heat load fluctuations. While a temperature measurement and control instrument monitors the gas temperature, it lacks a speed measurement function, and the cascaded heating system prevents simultaneous delivery of gas at different temperatures.

[0038] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0039] Example 1

[0040] As described in the background technology, the gas heating devices in the prior art ignore the different gas heating requirements of users in different experiments and cannot output heated airflows of different temperatures at the same time. In order to solve the above technical problems, the present invention proposes a gas heating pipeline system.

[0041] Combine Figure 1 The gas heating pipeline system includes a support frame 3, within which a blower 1, a first pipeline 8, and two second pipelines 7 are mounted. The blower 1 is fixed to one side of the support frame 3 along its width via a mounting plate, while the first pipeline 8 and the second pipeline 7 are located on the other side of the support frame 3 along its width. To filter impurities from the air, a gas filter 2 is installed at the inlet of the blower 1. The gas filter 2 is connected to the blower 1, and the outlet of the blower 1 is connected to the first pipeline 8 and the second pipeline 7 via a tee. The first pipeline 8 and the second pipeline 7 are independent of each other, facilitating heating control between different pipelines and achieving simultaneous heating of airflows at different temperatures.

[0042] To save space, the first and second pipelines 8 and 7 are designed as a U-shaped structure. The connection between the first and second pipelines 8 and 7 and the blower 1 is located at its lower portion. An electric heater is installed at the end of the second pipeline 7 to heat the gas within the pipelines. The first and second pipelines 8 and 7 are connected by a hose 7. In other words, the first and second pipelines 8 and 7 are respectively composed of a stainless steel pipe, a hose 7, and a stainless steel pipe connected in sequence. The first pipeline 8 does not have an electric heater installed, so that the first pipeline 8 outputs normal temperature airflow, while the two second pipelines 7 can output heated airflow of the same or different temperatures.

[0043] A control valve 5, a first temperature sensor, a speed sensor and a second temperature sensor are respectively installed on the first pipeline 8 and the second pipeline 7 along the flow direction of the gas. The first temperature sensor, the speed sensor and the second temperature sensor are located inside the pipeline. The first temperature sensor is located behind the control valve 5, and the second temperature sensor is fixed on the electric heater. Since the pipeline in this embodiment has a U-shaped structure, the gas flow speed and state are affected by the pipeline structure. Therefore, the speed sensor is located at the upper part of the pipeline and away from the pipeline corner.

[0044] The opening and closing of the corresponding pipeline is controlled by controlling the opening and closing of the control valve 5. The temperature information of the airflow just entering the pipeline is collected by the first temperature sensor, which can reflect the temperature information of the gas before heating. The flow speed of the gas in the pipeline is collected by the speed sensor. The faster the gas flow speed, the greater the airflow pressure. The temperature information of the gas after heating is collected by the second temperature sensor.

[0045] In this embodiment, the support frame 3 is a quadrilateral column frame structure composed of transverse support rods and longitudinal support rods. Six pulleys 4 are installed at the bottom of the support frame 3, three on each side, so that the entire system can move in any direction.

[0046] The hose 7 is made of PVC, the first temperature sensor and the second temperature sensor are thermocouples, the speed sensor is RLSW4AM8 24V AC / DC, and the electric heater is a ceramic disc heater.

[0047] The working method of this embodiment is as follows:

[0048] When in use, start the blower 1 and the electric heater, open the corresponding control valves 5 on the first pipeline 8 and the second pipeline 7, and the blower 1 serves as a power source to deliver airflow to the first pipeline 8 and the second pipeline 7 respectively. The heater heats the airflow, and the speed sensor collects the flow rate of the gas in the pipeline. When the heated airflow in any pipeline reaches the flow rate requirement required by the user, the user closes the corresponding control valve 5, and the second temperature sensor collects the temperature information of the heated gas. When the heated airflow in any pipeline reaches the temperature requirement of the user, the user turns off the corresponding electric heater and transmits the heated airflow to the subsequent processing system through the hose 7.

[0049] Example 2

[0050] The difference between this embodiment and the first embodiment is that it further includes a controller, the first temperature sensor and the second temperature sensor are communicatively connected to the controller via the first I / O module, the speed sensor 6 is communicatively connected to the controller via the second I / O module, and the controller is electrically connected to the control valve 5 and the electric heater, respectively.

[0051] In this embodiment, the controller is a PLC controller, and the first I / O module and the second I / O module are common I / O modules in the prior art. This embodiment does not make any improvements to them, and they will not be described in detail here.

[0052] The working method of this embodiment is described by taking the control of a second pipeline as an example:

[0053] The user can set the temperature threshold and wind speed threshold in the PLC controller according to the test requirements. The second temperature sensor collects the temperature information after heating and transmits it to the PLC controller. When the temperature of the heated air flow reaches the temperature threshold, the controller controls the electric heater on the second pipeline to turn off; the speed sensor collects the speed information and transmits it to the PLC controller. When the air flow speed after heating reaches the wind speed threshold, the controller controls the control valve 5 on the second pipeline to close.

[0054] Although the above description of the specific implementation methods of the present invention is combined with the accompanying drawings, it does not limit the scope of protection of the present invention. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present invention, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present invention.
