Description

Technical Field

[0001] The present invention relates to a steam generator, in particular to a multifunctional pure steam generator. Background Art

[0002] A pure steam generator is a device for producing pure steam. Traditional pure steam generators are generally of two types: one is a pure steam generator + an electric steam generator, which is a combination of two devices to complete the production of pure steam. This device only produces pure steam; the other is a combination of an electrically heated pressure vessel + a separation device to achieve the production of pure steam. This device also only produces pure steam. The above two types of pure steam generators must be designed and manufactured in strict accordance with the pressure vessel standards and are special equipment. The second device is an improvement over the first combination, but it is quite troublesome in design, manufacturing and application. Moreover, after production, the equipment is large and occupies a large space. Both devices can only produce pure steam and cannot directly produce distilled water for injection. Therefore, the development of a multifunctional pure steam generator has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0003] The present invention is to solve the above-mentioned deficiencies and provides a multifunctional pure steam generator.

[0004] The above-mentioned object of the present invention is achieved by the following technical solution: a multifunctional pure steam generator, comprising a feed water pump, an energy converter, an electric heater, a non-condensable gas output device, a distilled water output valve, a No. 2 condenser, a separation tower, a No. 1 condenser, a saturated separator and a pure steam output valve;

[0005] The feed water pump is divided into two outputs, one is connected to the energy converter through the sixth feed water pipe, and the other is connected to the first condenser through the first feed water pipe;

[0006] The output end of the energy converter is connected to the non-condensable gas output device through the second feed water pipe, the non-condensable gas output device is connected to the electric heater through the third feed water pipe, the electric heater is connected to the separation tower, the separation tower is connected to the saturated separator, and the saturated separator is connected to the pure steam output valve; a first discharge pipe is provided at the bottom of the electric heater and is connected to the energy converter;

[0007] The non-condensable gas output device is provided with a non-condensable gas discharge pipe connected to the energy converter;

[0008] The saturated separator and the pure steam output valve are connected to the No. 1 condenser via a pure steam pipe, the output end of the No. 1 condenser is connected to the No. 2 condenser via a fourth feed water pipe, the No. 2 condenser is provided with a distilled water output valve, and is connected to the energy converter via a fifth feed water pipe; the energy converter is provided with a second discharge pipe.

[0009] Further, the energy converter includes a first heat exchanger and a second heat exchanger;

[0010] The first heat exchanger is provided with two input ends, which are respectively connected to the first discharge pipe and the fifth feed water pipe; the first heat exchanger is provided with two output ends, which are respectively connected to the second feed water pipe and the second discharge pipe;

[0011] The second heat exchanger is provided with two input ends, which are respectively connected to the sixth feed water pipe and the non-condensable gas discharge pipe; the second heat exchanger is provided with two output ends, which are respectively connected to the second feed water pipe and the second discharge pipe.

[0012] The working principle of this invention is that after the feed water enters, it is heated by an electric heater to generate steam. Then, it is separated by a centrifugal separator to remove pyrogens and other impurities, and pure steam is output. The pure steam enters the condenser and, after heat energy exchange, can produce distilled water for injection.

[0013] During operation, feed water passes through the sixth feed water pipe and enters the second heat exchanger of the energy converter. It then flows through the second feed water pipe into the non-condensable gas (NCG) output device, which is a water vapor separator. The heated feed water is then fed into the electric heater via the third feed water pipe, while the NCG discharge pipe discharges the non-condensable gases. This condensed water is then discharged through the second heat exchanger and discharged through the second discharge pipe, effectively improving water quality. The feed water is then heated and evaporated by the electric heater, leaving a high-temperature condensed water stream. This water flows out of the first discharge pipe below the electric heater, where it is cooled by the first heat exchanger and ultimately discharged through the second discharge pipe. The steam enters the separation tower, where it separates the water vapor and becomes pure steam. The pure steam then enters the saturated separator for further separation before being discharged through the pure steam output valve.

[0014] When the valve is closed, pure steam flows from the pure steam pipe between the pure steam output valve and the saturated separator to the first condenser. The feed water pump injects feed water into the first condenser through the first feed water pipe, which serves as cooling water for the pure steam. This cooling water flows through the fourth feed water pipe and then through the second condenser, where distilled water from the pure steam is output from the distilled water delivery valve. The cooling water flowing from the second condenser flows through the fifth feed water pipe into the first heat exchanger of the energy converter and enters the second feed water pipe as feed water. This achieves multifunctional operation.

[0015] The advantages of the present invention compared with the prior art are:

[0016] 1. The present invention adopts a combined design of a tubular heater, a separation tower, a centrifugal separator, a non-condensable gas output device, and an electric heater, so that purified water enters, is heated, evaporated, and separated to produce pure steam. It can also produce "water for injection" that meets the requirements of the "Chinese Pharmacopoeia" through a condenser.

[0017] 2. Since most of the components of the pure steam generator are pipeline structures, its design and manufacturing do not fall within the scope of "pressure vessels". The equipment is small in size and occupies less space, which greatly simplifies the design, manufacturing and use specifications.

[0018] 3. This pure steam generator realizes internal recycling of heat energy through the condenser and energy converter device, achieving the effect of energy saving and emission reduction. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The present invention is further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 、 Figure 2 As shown, a multifunctional pure steam generator includes a feed water pump 10, an energy converter 9, an electric heater 8, a non-condensable gas output device 7, a distilled water output valve 6, a second condenser 5, a separation tower 4, a first condenser 3, a saturated separator 2 and a pure steam output valve 1;

[0024] The feed water pump 10 is divided into two outputs, one is connected to the energy converter 9 through the sixth feed water pipe 19, and the other is connected to the first condenser 3 through the first feed water pipe 13;

[0025] The output end of the energy converter 9 is connected to the non-condensable gas output device 7 through the second feed water pipe 16, the non-condensable gas output device 7 is connected to the electric heater 8 through the third feed water pipe 12, the electric heater 8 is connected to the separation tower 4, the separation tower 4 is connected to the saturated separator 2, and the saturated separator 2 is connected to the pure steam output valve 1; the bottom of the electric heater 8 is provided with a first discharge pipe 11, which is also connected to the energy converter 9;

[0026] The non-condensable gas output device 7 is provided with a non-condensable gas discharge pipe 18 connected to the energy converter 9;

[0027] The saturated separator 2 and the pure steam output valve 1 are connected to the No. 1 condenser 3 via a pure steam pipe 17. The output end of the No. 1 condenser 3 is connected to the No. 2 condenser 5 via a fourth feed water pipe 14. The No. 2 condenser 5 is provided with a distilled water output valve 6 and is connected to the energy converter 9 via a fifth feed water pipe 15. The energy converter 9 is provided with a second discharge pipe 20.

[0028] Furthermore, the energy converter 9 includes a first heat exchanger 901 and a second heat exchanger 902;

[0029] The first heat exchanger 901 has two input ends, which are respectively connected to the first discharge pipe 11 and the fifth feed water pipe 15; the first heat exchanger 901 has two output ends, which are respectively connected to the second feed water pipe 16 and the second discharge pipe 20;

[0030] The second heat exchanger 902 has two input ends, which are respectively connected to the sixth feed water pipe 19 and the non-condensable gas discharge pipe 18; the second heat exchanger 902 has two output ends, which are respectively connected to the second feed water pipe 16 and the second discharge pipe 20.

[0031] The working principle of this invention is that after the feed water enters, it is heated by an electric heater to generate steam. Then, it is separated by a centrifugal separator to remove pyrogens and other impurities, and pure steam is output. The pure steam enters the condenser and, after heat energy exchange, can produce distilled water for injection.

[0032] During operation, feed water passes through the sixth feed water pipe 19 and enters the second heat exchanger 902 of the energy converter 9. It then flows through the second feed water pipe 16 into the non-condensable gas output device 7. The non-condensable gas output device 7 (which is a water vapor separator) separates the heated feed water into water and gas. The water is then fed into the electric heater 8 via the third feed water pipe 12, while the gas is discharged through the non-condensable gas discharge pipe 18. The non-condensable gas is then discharged through the second heat exchanger 902 as condensed water, which is then discharged through the second discharge pipe 20, effectively improving the water quality. After the feed water is heated and evaporated by the electric heater 8, the remaining water forms high-temperature condensed water. This water flows through the first discharge pipe 11 below the electric heater 8, cools in the first heat exchanger 901, and is ultimately discharged through the second discharge pipe 20. The steam enters the separation tower 4, where it undergoes water vapor separation and becomes pure steam. The pure steam then enters the saturated separator 2 for further separation before being discharged through the pure steam output valve 1.

[0033] When valve 1 is closed, pure steam flows from pure steam pipe 17 between pure steam output valve 1 and saturated separator 2 to condenser No. 1 3. Feed water pump 10 injects feed water into condenser No. 1 3 through first feed water pipe 13, serving as cooling water for the pure steam. This cooling water then flows through fourth feed water pipe 14 and then through condenser No. 2 5, resulting in distilled water from the pure steam being output from distilled water delivery valve 6. Cooling water flowing from condenser No. 2 5 flows through fifth feed water pipe 15 into first heat exchanger 901 of energy converter 9, where it enters second feed water pipe 16 as feed water. This achieves multifunctional operation.
