Description

Technical Field

[0001] The utility model relates to the technical field of material heating, in particular to a steam circulation system for heating materials. Background Art

[0002] Steam heating is a common and efficient heating method. Its principle is to transport steam through a pipe to the vicinity of the heated object, and use the high temperature and high pressure characteristics of steam to make the heated object absorb the heat of the steam, thereby achieving the purpose of heating.

[0003] At present, steam heating is usually achieved by using a steam generator (i.e., a boiler) to heat water into hot water using the thermal energy of fuel or other energy sources to generate steam, which is then transmitted to the outside of the equipment to be heated, thereby achieving the function of heating the material.

[0004] However, although part of the heat in the steam flow heating process has been used to heat the heating equipment, more steam is directly discharged into the external atmosphere, which greatly causes heat waste. Moreover, if too many heating devices are required, only one boiler is used to produce steam, and the steam is discharged to the heating equipment in sequence through pipelines. As a result, the steam temperature obtained by the heating equipment close to the boiler will be too high, while the steam temperature obtained by the heating equipment far away from the boiler will be too low (because there will always be heat loss in the transmission of steam in the pipeline), which affects the heating speed of steam on the material. Utility Model Content

[0005] Therefore, in order to solve the above-mentioned shortcomings, the utility model provides a steam circulation system which is convenient for heating materials. The steam circulation system can be used for steam heating of several devices to be heated and the heated steam can be recovered for recycling. The steam can be heated as a whole by a first heating device. At the same time, by equipping the pipeline where each heating device is located with a second heating device, it can effectively prevent the temperature from being too low due to heat loss during the transmission process of the steam, thereby ensuring the heating efficiency of the material.

[0006] The utility model is implemented by constructing a steam circulation system for heating materials, comprising a first heating device for generating steam;

[0007] A first row of pipes, interconnected with the first heating device and provided with a plurality of second rows of pipes at the exhaust end;

[0008] A first inlet pipe is interconnected with the first heating device and is provided with a plurality of second inlet pipes at the inlet end;

[0009] The number of the second rows of tubes and the number of the second inlet tubes correspond and are combined one by one to form a number of equipment positions, and a second heating device is also arranged on each of the second rows of tubes;

[0010] The first row of pipes is also provided with a pump body for driving the steam to flow.

[0011] Specifically, the first heating device is installed on a plane, and the plurality of second-row tubes are fixed to the plane via connecting rods.

[0012] According to the technical features described in the previous paragraph, setting the plane is convenient for installing the first heating device, and is also convenient for fixing the row pipes to prevent movement or even falling off due to the flow of steam.

[0013] Specifically, a valve body is also provided on each of the second row of pipes.

[0014] According to the technical features described in the previous paragraph, the valve body is provided to facilitate the control of the steam flow in each second row of pipes. Combined with the second heating device on the second row of pipes, the temperature of the steam delivered to each heating device can be made consistent.

[0015] Specifically, a waste heat discharge pipe is provided between two adjacent second inlet pipes on the first inlet pipe, and a connection portion for facilitating connection with an external device to be heated is provided at the end of the waste heat discharge pipe.

[0016] According to the technical features described in the previous paragraph, the waste heat discharge pipe is provided to facilitate the application of the heat carried by the steam discharged from the heating equipment to the remaining equipment to be heated, thereby maximizing the use of the heat of the steam.

[0017] Specifically, an external thread is provided on the connection portion of the waste heat discharge pipe.

[0018] According to the technical features described in the previous paragraph, an external thread is provided at the outer end of the waste heat discharge pipe to facilitate movable connection with the external equipment to be heated, so as to facilitate quick disassembly and assembly.

[0019] Specifically, a plug is movably installed on the connection portion of the waste heat discharge pipe.

[0020] According to the technical features described in the previous paragraph, installing a plug on the connection part of the waste heat discharge pipe is to ensure that when the waste heat discharge pipe is not connected to the external equipment to be heated, the steam flowing inside the waste heat discharge pipe will not be directly discharged from the waste heat discharge pipe into the atmosphere, thereby causing the steam to be unable to circulate.

[0021] Specifically, a flange connection portion for connecting to an external device to be heated is provided at the exhaust end of each of the second row of pipes and the intake end of each of the second inlet pipes.

[0022] According to the technical features described in the previous paragraph, the flange connection part at the second row of pipes and the second inlet pipe end is provided to ensure a stable and detachable connection with the equipment to be heated while reducing leakage.

[0023] The utility model has the following beneficial effects:

[0024] The steam circulation system can facilitate the recycling of steam in several devices to be heated during the steam heating process, and a second heating device is arranged on the pipeline where each device to be heated is located, which can effectively prevent the steam temperature from becoming low due to excessive steam transmission distance, thereby affecting the efficiency of steam heating.

[0032] The technical solution of the present invention is further specifically described below through specific embodiments in combination with the accompanying drawings; it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not intended to limit the present invention in any way; the accompanying drawings in the present invention are only used to assist in the description of the embodiments and to facilitate understanding, and are not intended to limit the present invention in any way.

[0033] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification so that people familiar with this technology can understand and read them, and are not used to limit the conditions under which the present invention can be implemented. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical contents disclosed in the present invention without affecting the effects and purposes that can be achieved by the present invention.

[0034] As described in the background technology, after existing steam heating equipment heats the material, the steam is often discharged directly, which can easily cause heat waste (because the steam will retain a part of the heat after heating, and the direct discharge of this part of the heat causes waste). In addition, when heating several devices to be heated, the temperature of the steam cannot be guaranteed for the devices to be heated that are far away from the steam heating source due to the long steam transmission distance, resulting in the steam temperature of this part being too low, affecting the heating efficiency.

[0035] For the reasons stated above, please refer to the attached Figure 1 , the utility model provides a steam circulation system for heating materials, comprising a first heating device 2 for generating steam;

[0036] A first row of pipes 3 is interconnected with the first heating device 2 and a plurality of second rows of pipes 5 are provided at the exhaust end;

[0037] A first inlet pipe 9 is interconnected with the first heating device 2 and is provided with a plurality of second inlet pipes 10 at the inlet end;

[0038] The number of the second row of tubes 5 and the number of the second inlet tubes 10 correspond and are combined one by one to form a plurality of equipment positions, and a second heating device 7 is also arranged on each second row of tubes 5;

[0039] The first row of pipes 3 is also provided with a pump body 4 for driving the steam to flow.

[0040] Furthermore, the first heating device is configured as a steam generator, which generates steam after heating water and flows through the pump body, and the second heating device can be configured as an electric heater to further heat the flowing steam.

[0041] Specifically, the first heating device 2 is installed on a plane 1 , and the plurality of second-row tubes 5 are fixed to the plane 1 via connecting rods 6 .

[0042] According to the technical features described in the previous paragraph, setting the plane is convenient for installing the first heating device, and is also convenient for fixing the row pipes to prevent movement or even falling off due to the flow of steam.

[0043] Specifically, a valve body 8 is further provided on each of the second row of pipes 5 .

[0044] According to the technical features described in the previous paragraph, the valve body is provided to facilitate the control of the steam flow in each second row of pipes. Combined with the second heating device on the second row of pipes, the temperature of the steam delivered to each heating device can be made consistent.

[0045] Furthermore, the valve body can adopt an automatic control valve, and the valve can be controlled by means other than manpower, such as electric, pneumatic, hydraulic or electromagnetic drive. Its characteristics are: easy to use and safe; it can be controlled on site or remotely; it can control a single valve or multiple valves in a centralized manner; it can perform simple switch control or regulation control; it can realize programmed control in conjunction with an electronic computer. Due to the need for remote control, there is generally valve signal feedback - light signal or 4-20mA signal feedback, which is used for valve control.

[0046] Furthermore, the valve body is controlled by a temperature sensor of the device to be heated and a corresponding control circuit. When the temperature sensor of the device to be heated detects that the temperature of the flowing steam is too high, the valve body is controlled to reduce the opening of the valve, thereby reducing the flow rate of the steam and further reducing the temperature of the steam, and vice versa.

[0047] Specifically, a waste heat discharge pipe 11 is provided between two adjacent second inlet pipes 10 on the first inlet pipe 9 , and a connection portion for facilitating connection with an external device to be heated is provided at the end of the waste heat discharge pipe 11 .

[0048] According to the technical features described in the previous paragraph, the waste heat discharge pipe is provided to facilitate the application of the heat carried by the steam discharged from the heating equipment to the remaining equipment to be heated, thereby maximizing the use of the heat of the steam.

[0049] Specifically, an external thread is provided on the connection portion of the waste heat discharge pipe 11 .

[0050] According to the technical features described in the previous paragraph, an external thread is provided at the outer end of the waste heat discharge pipe to facilitate movable connection with the external equipment to be heated, so as to facilitate quick disassembly and assembly.

[0051] Specifically, a plug 12 is movably installed on the connection portion of the waste heat discharge pipe 11 .

[0052] According to the technical features described in the previous paragraph, installing a plug on the connection part of the waste heat discharge pipe is to ensure that when the waste heat discharge pipe is not connected to the external equipment to be heated, the steam flowing inside the waste heat discharge pipe will not be directly discharged from the waste heat discharge pipe into the atmosphere, thereby causing the steam to be unable to circulate.

[0053] Specifically, a flange connection portion for connecting to an external device to be heated is provided at the exhaust end of each of the second row of pipes 5 and the intake end of each of the second intake pipes 10 .

[0054] According to the technical features described in the previous paragraph, the flange connection part at the second row of pipes and the second inlet pipe end is provided to ensure a stable and detachable connection with the equipment to be heated while reducing leakage.

[0055] When the steam circulation system is in use, the equipment to be heated is pre-connected with the second row of pipes 5 and the second inlet pipe 10 at the corresponding position. If there are spare second row of pipes 5 and second inlet pipes 10 (i.e., equipment positions), the valve body 8 and the second heating device 7 corresponding to the equipment position are directly closed, and the waste heat discharge pipe 11 is blocked by the plug 12. Then, the first heating device 2 heats the water to generate hot steam, which enters the first row of pipes 3 under the negative pressure of the pump body 4, and then enters the second inlet pipe 10 where the equipment position where the equipment to be heated is installed flows to the equipment to be heated for heating. If the temperature sensor at the position of the equipment to be heated senses that the temperature is too low or too high, the control system (such as a PLC automatic control system) will control the movement of the valve body 8 at the heating line and The second heating device 7 (because it is not convenient to adjust the heating temperature when starting and stopping the second heating device, it is more convenient to adjust the valve opening by moving the valve body 8, thereby controlling the steam flow rate. This adjustment method is more convenient and rapid) is started and stopped until the transmitted steam temperature reaches the preset temperature range of the equipment to be heated. After the steam heating is completed, the waste heat steam is discharged from the second inlet pipe 10 to the first inlet pipe 9 and then flows back to the first heating device 2 (at this time, the corresponding waste heat discharge pipe 11 is installed with a plug 12) or is discharged to the waste heat discharge pipe 11 to the remaining equipment to be heated (at this time, the corresponding waste heat discharge pipe 11 is installed with the remaining equipment to be heated) and then flows back to the first inlet pipe 9 for heating, and finally flows back to the first heating device 2 to complete the steam heating cycle.

[0056] The above description is a detailed description of the preferred feasible embodiment of the utility model, but the embodiment is not used to limit the scope of the patent application of the utility model. All equivalent changes or modified changes completed under the technical spirit suggested by the utility model should fall within the patent scope covered by the utility model.
