It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0033] Before introducing the technical solution of the present application, the technical problems in the related technology are introduced in detail.

[0034] Industrial steam, as an indispensable source of heat energy in the industrial field, mainly comes from the combustion of boiler fuel. This heat energy is widely used in processes such as heating and humidification, and can also generate power to drive equipment. For example, in pharmaceutical factories, industrial steam is particularly important. It is widely used in heating and sterilization in production, as well as the humidification function of air conditioners.

[0035] The main mode of steam supply for industrial enterprises in my country is centralized heating, which is generally concentrated in the northern region and enterprise cluster areas, such as chemical industry areas, textile areas, high-tech development zones, economic development zones, industrial parks, etc. Data shows that the current industrial steam market is concentrated in East China, North China, Northwest China and Central China, with market scales accounting for 36.19%, 19.64%, 12.24% and 10.76% respectively.

[0036] The heat of steam is used to realize industrial production processes. Overall, my country's steam heating capacity is constantly improving. In 2014, China's steam heating capacity was about 84,700 tons / hour, and it rose to 105,900 tons / hour in 2021.

[0037] According to the pressure and temperature characteristics of steam, we can divide it into two types: saturated steam and superheated steam.

[0038] At present, in industrial enterprises, the steam used is mostly saturated steam with a grade between 0.1Mpa and 0.5Mpa, which is mostly used for humidification, cooking, heating, heating and thermal reaction processes. Generally, it is mainly produced by purchased steam and gas. The price of purchased steam is between 200-250 yuan / ton, and the price of gas production varies according to the gas price, which is generally close to 400 yuan / ton.

[0039] Take a chemical plant as an example. It uses 16,000 tons of 0.5Mpa saturated steam per year and uses a gas-fired steam boiler. The gas price is 4 yuan / m 3 The average gas consumption per ton of steam is 93Nm 3 , equivalent to a steam price of 372 yuan / ton, and there is a risk of rising prices.

[0040] Traditional steam production methods are expensive due to factors such as high energy consumption, high equipment maintenance costs, and high costs for professional operators. In addition, the operation of boilers has certain safety risks, such as potential accidents such as explosions, leaks, and combustion, which pose a threat to the safety of personnel and equipment. In addition, traditional steam production equipment also has the cost and pressure of cumbersome procedures for annual inspections and safety supervision.

[0041] In view of this, in order to solve the above problems, the present application provides a steam supply device 1. Figure 1 , Figure 2 and Figure 3. The steam supply device 1 of this embodiment includes a shell 10, a heat pump 20, a compressor 30 and an energy storage system 40. The shell 10 is surrounded by a receiving space 11, and the shell 10 is a fireproof shell 10. The heat pump 20 is received in the receiving space 11, and the heat pump 20 includes a heat pump body 21, a first input end 22 and a first output end 23, the first input end 22 is used to input a medium of a first temperature into the heat pump body 21, the heat pump body 21 is used to process the medium of the first temperature into steam of a second temperature, and the first output end 23 is used to output steam of a second temperature, and the second temperature is higher than the first temperature. The compressor 30 is accommodated in the accommodation space 11, and the compressor 30 includes a compression body 31, a second input end 32 and a second output end 33. The second input end 32 is connected to the first output end 23. The second input end 32 is used to receive steam at a second temperature and transmit it to the compression body 31. The compression body 31 is used to compress the steam at the second temperature to obtain steam at a third temperature, and output it through the second output end 33. The third temperature is higher than the second temperature, and the pressure value of the steam at the third temperature is greater than the pressure value of the steam at the second temperature. The energy storage system 40 is accommodated in the accommodation space 11, and the energy storage system 40 is electrically connected to the heat pump 20 and the compressor 30, and supplies power to the heat pump 20 and the compressor 30.

[0042] Specifically, the steam supply equipment 1 can be but is not limited to being used in industries such as electroplating, textile printing and dyeing, food processing, chemical industry and sewage treatment. It can be understood that the application scenario of the steam supply equipment 1 should not be a limitation of the steam supply equipment 1 provided in this embodiment.

[0043] Optionally, the shell 10 is made of sheet metal, so that the shell 10 has good structural strength and durability. The shell 10 is surrounded by a receiving space 11, and the receiving space 11 is used to receive the heat pump 20, the compressor 30 and the energy storage system 40.

[0044] Preferably, the shell 10 is subjected to fireproof treatment, for example, a fireproof interlayer is prepared in the sheet metal material of the shell 10. This effectively isolates the steam supply device 1 from the external environment, prevents the device from catching fire when it is overheated, and can reduce the impact of the external environment on the internal temperature of the device, thereby ensuring the stable operation of the steam supply device 1 and ensuring the safety of the steam supply device 1.

[0045] The material of the fireproof interlayer includes but is not limited to flame retardant foam, mineral fiberboard, ceramic fiber, aluminum silicate fiber and the like.

[0046] Optionally, a steel foundation is also provided at the bottom of the shell 10, and the steel foundation is used to carry and support the steam supply equipment 1, ensuring the stability and safety of the steam supply equipment 1 during operation, and enabling the steam supply equipment 1 to be quickly adapted to various application scenarios.

[0047] Optionally, the heat pump body 21 refers to an ultra-high temperature heat pump 20. The working process of the ultra-high temperature heat pump 20 includes evaporation, compression, condensation, throttling and re-evaporation, etc. By cycling the above process, the ultra-high temperature heat pump 20 can convert the heat energy in the low-temperature heat source into the heat energy in the high-temperature heat carrier.

[0048] Optionally, the heat pump 20 receives a medium at a first temperature through the first input end 22 and converts the medium at the first temperature into steam at a second temperature.

[0049] The medium at the first temperature includes but is not limited to steam condensate, or low-grade waste heat, etc., wherein the low-grade waste heat may refer to hot water with a temperature less than or equal to 80°C.

[0050] Optionally, the steam at the second temperature is high temperature steam, wherein the high temperature steam can be understood as water vapor with a temperature higher than 100° C. Further optionally, the value of the second temperature satisfies: 100° C.-110° C.

[0052] In one embodiment of the present application, the ultra-high temperature heat pump 20 absorbs heat from factory waste heat and converts a medium at a first temperature into steam at a second temperature through circulation, for example, converting steam condensate or low-grade waste heat (hot water ≤80°C) into high-temperature steam of 100°C-110°C, and the energy conversion efficiency (Coefficient Of Performance, COP) of the process is 2.4.

[0053] Optionally, the compressor 30 is connected to the first output end 23 of the heat pump 20 through the second input end 32, and receives the steam at the second temperature output by the heat pump 20. The compressor 30 is used to compress the steam at the second temperature and increase its temperature and pressure values.

[0054] Further optionally, the pressure value of the steam at the second temperature satisfies: 0.1Mpa-0.2Mpa. The pressure value of the steam at the third temperature satisfies: 0.3Mpa-0.5Mpa. That is, the pressure value of the steam at the third temperature is greater than the pressure value of the steam at the second temperature. In other words, the temperature and pressure values ​​of the steam at the second temperature output by the ultra-high temperature heat pump 20 are further increased after being compressed by the compressor 30.

[0055] Further optionally, the steam at the second temperature is saturated steam, and the steam at the third temperature is also saturated steam. The saturated steam can be understood as steam in a saturated state.

[0056] Optionally, the steam supply device 1 can be electrically connected to an external power grid, and obtain electric energy through the external power grid, and then enable the heat pump 20 and the compressor 30 to operate through power distribution. An energy storage system 40 is also provided inside the steam supply device 1, and the energy storage system 40 can store the electric energy input from the external power grid and supply power to the heat pump 20 and the compressor 30.

[0057] Preferably, the energy storage system 40 stores electric energy during off-peak periods and supplies power to the heat pump 20 and the compressor 30 during peak periods, thereby achieving peak-to-valley shifting of energy storage and further reducing steam costs.

[0058] In summary, the steam supply device 1 provided in this embodiment realizes stable, low-cost low-pressure saturated steam supply by utilizing electricity and low-grade waste heat resources, combined with ultra-high temperature heat pump 20, compressor 30 and valley power energy storage system 40. Compared with the traditional steam supply method, the steam supply device 1 integrates the heat pump 20, the compressor 30 and the energy storage system 40. Moreover, the steam supply device 1 uses electricity for operation, which is more energy-saving and safer than the method of preparing steam by boiler heating, and effectively solves the problems of high cost, high safety risk, and cumbersome annual inspection and safety supervision in traditional steam supply. With the in-depth promotion of energy conservation and emission reduction, the steam supply device 1 can have a broader market application prospect.

[0059] Please refer again Figure 2 and Figure 3 The steam supply device 1 has an output port 50, which is exposed in the shell 10 and is used to transmit the steam at the third temperature to the outside of the steam supply device 1. The heat pump 20 also includes a third input port 24, which is exposed in the shell 10 and is used to receive condensed water converted from the steam at the third temperature, and the heat pump body 21 can process the condensed water into steam at the second temperature.

[0060] Optionally, one end of the output port 50 is connected to the second output end 33 of the compressor 30 , and the other end of the output port 50 is connected to the external environment of the steam supply device 1 , and outputs the steam at the third temperature.

[0061] Further optionally, a gas distribution cylinder is further provided outside the steam supply device 1, and the output port 50 is connected to the gas distribution cylinder, and the gas distribution cylinder is used to distribute and transport the steam at the third temperature to different production workshops.

[0062] Optionally, the steam at the third temperature can be converted into condensed water after use in the generation process. The heat pump body 21 also receives the condensed water through the third input port 24, and converts the condensed water into steam at the second temperature through a circulation process, thereby realizing the recycling of steam, improving the flexibility of use of the steam supply equipment 1, reducing energy waste, and further improving the energy-saving and emission reduction effects of the steam supply equipment 1.

[0063] Please refer again Figure 1 and Figure 2 The steam supply device 1 further includes a distribution component 60, which includes a first connection end 61, a distribution body 62 and a second connection end 63. The distribution body 62 is electrically connected to the first connection end 61. The distribution body 62 receives a first electrical signal output by a power grid through the first connection end 61. The distribution body 62 is used to distribute the first electrical signal and output a second electrical signal.

[0065] Optionally, the power distribution body 62 can receive power transmitted from an external power grid through the first connection terminal 61, that is, receive the first electrical signal. The power distribution body 62 can distribute the received electrical energy and adjust the voltage according to the needs of different electrical devices. For example, after receiving the first electrical signal, the power distribution body 62 can also output a second electrical signal to the heat pump 20, and the second electrical signal is used to provide power to the heat pump 20 so that the heat pump 20 can operate normally.

[0066] It can be understood that the power distribution body 62 can also be electrically connected to the compressor 30 and other electrical devices, and distribute power to each electrical device.

[0067] Please refer again Figure 2The power distribution component 60 also includes a third connection terminal 64, and the third connection terminal 64 is electrically connected to the power distribution body 62 and the energy storage system 40. In a first preset time period, the power distribution body 62 receives the first electrical signal and outputs a third electrical signal. The energy storage system 40 receives the third electrical signal through the third connection terminal 64 and is used to store electrical energy, wherein the first preset time period is a valley power period. In a second preset time period, the energy storage system 40 outputs a fourth electrical signal to the power distribution body 62, and the power distribution body 62 receives the fourth electrical signal and supplies power to the heat pump 20, wherein the second preset time period is a peak period.

[0068] The valley period can be understood as a period of time when the power demand of the power grid is relatively low, and the peak period can be understood as a period of time when the power demand of the power grid is high and the power consumption is large.

[0069] In this embodiment, when the power grid is in a valley period, that is, in a first preset time period, the energy storage system 40 receives the electrical signal transmitted by the power grid through the power distribution body 62 and stores energy. When the power grid is in a peak or peak period, that is, in a second preset time period, the energy storage system 40 supplies power to the heat pump 20 through the power distribution body 62, and the energy storage system 40 can also supply power to the compressor 30 and other electrical devices through the power distribution body 62. It can be understood that the steam supply equipment 1 provided in this embodiment, by shifting the peak load to fill the valley load of energy storage, can reduce the operating electricity cost of the equipment and further reduce the steam cost. In addition, the design of the energy storage system 40 can also effectively avoid the situation where the steam supply equipment 1 is short of power due to large power consumption during the peak period of the power grid, thereby ensuring that the steam supply equipment 1 can operate effectively in all time periods and improving the reliability of the steam supply equipment 1.

The first electrical connector 70 and the second electrical connector 80 are both cables, which can be easily installed and removed, thereby making the maintenance of the steam supply device 1 more convenient and reducing the cost of the steam supply device 1.

[0072] Please refer again Figure 4 The steam supply device 1 further includes a third electrical connector 90 , one end of which is electrically connected to the power distribution component 60 , and the other end of which is electrically connected to the power grid, and is used to transmit the first electrical signal output by the power grid to the power distribution component 60 .

[0073] Optionally, the third electrical connector 90 is a cable, which has good insulation performance, low cost, and is easy to disassemble, thereby ensuring the safety of the steam supply device 1, facilitating maintenance of the steam supply device 1, and further reducing the cost of the steam supply device 1.

[0074] Please refer again Figure 4 The steam supply device 1 further includes an electric energy monitor 12 , which is electrically connected to the first electrical connector 70 and is used to monitor the first electrical signal.

[0076] In this embodiment, the power monitor 12 can be but is not limited to real-time detection of parameters such as voltage, current, frequency and power in the power grid. The steam supply equipment 1 monitors the first electrical signal transmitted by the power grid through the power monitor 12, which can not only improve the efficiency of power utilization, but also timely discover power quality problems, such as voltage fluctuations, current harmonics, power distortion, etc., thereby avoiding the impact of the first electrical signal instability on the safe operation of the steam supply equipment 1, and further ensuring the safety and reliability of the steam supply equipment 1.

[0081] In this embodiment, the control system 14 can centrally manage multiple devices such as the heat pump 20, the compressor 30, the energy storage system 40, the power monitor 12 and the steam meter 13, so as to improve the operating efficiency of the steam supply device 1.

And through the management of the control system 14, the energy storage system 40 can also be effectively utilized to improve the stability and reliability of the power system.

[0082] It should be noted that in this embodiment, only the electrical connection relationship between the control system 14 and the heat pump 20, the compressor 30, the energy storage system 40, the power monitor 12 and the steam meter 13 is configured, and no software improvement is made to the control system 14.
