Description

Technical field:

[0001] The utility model relates to the field of heat-conducting boilers, in particular to a heat-conducting oil temperature regulating system for heat-conducting boilers. Background technology:

[0002] In recent years, the market share of thermal oil boilers has been gradually increasing due to their advantages of low pressure and high temperature operation, safety, reliability and energy saving. In some industries, they are gradually replacing traditional steam boilers due to their unique advantages.

[0003] The thermal oil furnace directly heats the thermal oil with a heat source. A high-temperature oil pump circulates the heated oil in the liquid phase, delivering it to the heat-consuming equipment. The oil then returns to the thermal oil furnace from the heat-consuming equipment's outlet for reheating, forming a complete circulating heating system. The thermal oil furnace uses a digital temperature controller with alarms for overtemperature, low oil level, and overpressure.

[0004] Although the operating pressure of a thermal oil boiler is relatively low, the heat transfer fluid inside the boiler is hot and often flammable and explosive. Leakage during operation can cause fires, explosions, and other accidents, potentially resulting in casualties and property damage. Therefore, the safe operation and management of organic heat transfer fluid boilers must be given high priority.

[0005] The existing thermal oil temperature control system of the heat transfer boiler has some shortcomings. During use, it was found that due to the high temperature, the outlet flow meter and thermometer, although made of special materials, still have problems such as flow meter damage, inaccurate thermometer display, and inaccurate high-level tank oil level display. When replacing, the high temperature causes the pipeline to have a high temperature, which leads to safety hazards during the replacement process and can easily cause maintenance personnel to be injured. Utility model content:

[0006] The purpose of the utility model is to provide a heat transfer oil temperature regulating system for a heat transfer boiler.

[0012] The advantages of the utility model are as follows: the pressure gauge, thermometer, flow meter, sound and light alarm and cut-off valve are all connected to the PLC controller in the central control room through lines, which realizes centralized control and is convenient for observation and recording. At the same time, the setting of the sound and light alarm can transmit the alarm signal to the central control room as soon as a problem occurs in the thermal oil boiler, so that effective early warning and remedial measures can be taken in time, the cooling jacket can be started, and the installation pipe can be quickly cooled, so as to avoid damage to maintenance personnel caused by high temperature and reduce the occurrence of safety accidents.

Specific implementation method:

[0016] like Figures 1 to 2As shown, a heat-conducting oil temperature regulation system for a heat-conducting boiler includes a heat-conducting oil boiler 1, a central control room 2, a heat-conducting oil inlet pipe 3 and a heat-conducting oil outlet pipe 4. One end of the heat-conducting oil inlet pipe 3 is fixedly connected to and communicated with the heat-conducting oil input end of the heat-conducting oil boiler 1, and one end of the heat-conducting oil outlet pipe 4 is fixedly connected to and communicated with the heat-conducting oil output end of the heat-conducting oil boiler 1. A pressure gauge 5 and a thermometer 6 are installed on the heat-conducting oil inlet pipe 3 and the heat-conducting oil outlet pipe 4, a flow meter 7 is installed on the heat-conducting oil outlet pipe 4, an audible and visual alarm 8 is provided above the heat-conducting oil boiler 1, and a pressure gauge 5 and a thermometer 6 are installed on the heat-conducting oil inlet pipe 3 and the heat-conducting oil outlet pipe 4. A shut-off valve 9 is installed. The pressure gauge 5, thermometer 6, flowmeter 7, sound and light alarm 8 and shut-off valve 9 are electrically connected to the PLC controller in the central control room 2 through lines. A plurality of connecting pipes 10 are fixedly connected to the thermal oil inlet pipe 3 and the thermal oil outlet pipe 4. Each connecting pipe 10 is respectively communicated with the corresponding thermal oil inlet pipe 3 and the thermal oil outlet pipe 4. The top of each connecting pipe 10 is fixedly connected to a mounting pipe 11. Each pressure gauge 5, thermometer 6 and flowmeter 7 is fixedly installed on the top of the corresponding mounting pipe 11. A cooling jacket 12 is fixedly sleeved on the outside of each mounting pipe 11.

[0017] The installation pipe 11 is fixedly connected to the connecting pipe 10 via a flange, and a valve is fixedly installed on the connecting pipe 10.

[0018] A handle is fixedly connected to the outside of the cooling jacket 12 .

At the same time, in daily maintenance, a cooling jacket 12 is provided. When the pressure gauge 5, thermometer 6 and flow meter 7 are found to be damaged, the valve on the connecting pipe 10 can be closed first, so that the heat transfer oil is stopped from entering the connecting pipe 10, and the cooling jacket 12 is started to quickly cool the installation pipe 11. In this way, the operator can grab the handle by opening the connecting flange, remove the installation pipe 1, and replace or repair the damaged pressure gauge 5, thermometer 6 and flow meter 7, thereby avoiding damage to the maintenance personnel due to high temperature and reducing the occurrence of safety accidents.
