AI Technical Summary
When traditional steam generators generate steam by heating water, the heat loss of flue gas is large, resulting in low efficiency.
A high-temperature steam generator including a high-temperature furnace and a medium-temperature furnace is designed. The flue gas first generates high-pressure steam through the high-temperature furnace, and then further heats water through the medium-temperature furnace to generate lower-pressure steam, and sends the hot water from the medium-temperature furnace through the return pipe. Return to the high-temperature furnace to ensure a stable supply of steam.
Through phased heating, the heat loss of flue gas is effectively reduced, the efficiency of the steam generator is improved, and the stable supply of high-temperature steam is ensured.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of energy conversion equipment, in particular to a high-temperature steam generator. Background Art
[0002] High-temperature steam plays an important role in industrial applications. It is not only used for power generation, but also widely used in many fields such as chemical industry, petroleum refining, food processing and material science. Traditional steam generators usually rely on burning fossil fuels to heat water to produce steam.
[0003] At present, many enterprises use high-temperature flue gas generated by industrial production to heat water to produce water vapor. However, due to the continuous emission of flue gas, the flue gas after heat exchange still has a relatively high temperature, resulting in a large amount of heat loss. Utility Model Content
[0004] The utility model proposes a high-temperature steam generator based on the above technical problems.
[0005] A high-temperature steam generator comprises: a high-temperature furnace and a medium-temperature furnace, wherein the furnace tops of the high-temperature furnace and the medium-temperature furnace are both provided with steam outlet pipes, the high-temperature furnace and the medium-temperature furnace are both provided with flue gas heating pipes, a smoke inlet pipe is provided on one side of the high-temperature furnace, the smoke inlet pipe is connected with the flue gas heating pipe in the high-temperature furnace, the flue gas heating pipes in the high-temperature furnace and the medium-temperature furnace are connected through a connecting pipe, and the tail end of the flue gas heating pipe of the medium-temperature furnace is connected with a smoke exhaust pipe; a water return port is provided at the upper part of the high-temperature furnace, a water supply port is provided at the lower part of the medium-temperature furnace, a water return pipe is provided between the water return port and the water supply port, and a water pump is provided on the water return pipe; a water supply pipe and a drain pipe are also provided on the high-temperature furnace and the medium-temperature furnace.
[0006] Preferably, the flue gas heating tube is a coil.
[0007] Preferably, a plurality of the flue gas heating pipes distributed vertically are provided in both the high-temperature furnace and the medium-temperature furnace, and each of the flue gas heating pipes in the high-temperature furnace is arranged in one-to-one correspondence with the flue gas heating pipes in the medium-temperature furnace.
[0008] Beneficial effects: The device is equipped with a high-temperature furnace and a medium-temperature furnace. The flue gas first passes through the high-temperature furnace to produce high-temperature and high-pressure steam. The flue gas after cooling is passed into the medium-temperature furnace, which produces steam with relatively low temperature and pressure. The heated hot water can also be pumped from the medium-temperature furnace to the high-temperature furnace to ensure that the high-temperature furnace can emit steam stably. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 The structure of the utility model is shown Figure 1 ;
[0010] Figure 2 The structure of the utility model is shown Figure 2 ;
[0011] Figure 3 The internal structure diagram of the utility model is shown. DETAILED DESCRIPTION
[0012] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0013] like Figure 1 to Figure 3 A high-temperature steam generator is shown, comprising: a high-temperature furnace 1 and a medium-temperature furnace 2. A steam outlet pipe 4 is provided on the furnace top 3 of the high-temperature furnace 1 and the medium-temperature furnace 2. A flue gas heating pipe 6 is provided in the high-temperature furnace 1 and the medium-temperature furnace 2. The flue gas heating pipe 6 can be designed as a coil, and in a single furnace, a plurality of flue gas heating pipes can be arranged in upper and lower layers. The number of flue gas heating pipes 6 in the high-temperature furnace 1 and the medium-temperature furnace 2 is the same and corresponds to each other, and they are connected through a connecting pipe 10; a smoke inlet pipe 5 is provided on one side of the high-temperature furnace 1, and the high-temperature flue gas enters the flue gas heating pipe 6 in the high-temperature furnace 1 from the smoke inlet pipe 5 to heat the water in the high-temperature furnace 1 to generate high-temperature steam. The high-temperature flue gas will enter the medium-temperature furnace 2 after passing through the smoke heating pipe 6, and heat the water in the medium-temperature furnace 2 after the smoke heating pipe 6 in the medium-temperature furnace 2 is running. Since the temperature of the flue gas entering the medium-temperature furnace 2 drops, it will produce steam with a relatively low temperature. The flue gas after heat exchange will be discharged through the exhaust pipe 11 connected to the tail end of the flue gas heating pipe 6 of the medium-temperature furnace 2.
[0014] In order to ensure a stable supply of steam in the high-temperature furnace 1, a return water port 15 is set at the upper part of the high-temperature furnace 1, and a water supply port 14 is set at the lower part of the medium-temperature furnace 2. A return water pipe 12 is provided between the return water port 15 and the water supply port 14, and a water pump 13 is provided on the return water pipe 12. By directly sending the heated hot water into the high-temperature furnace 1, the heating process of the new cold water is reduced, thereby ensuring a stable supply of high-temperature steam in the high-temperature furnace 1.
[0015] The high temperature furnace 1 and the medium temperature furnace 2 are also provided with normal water supply pipes 7 and drainage pipes 8 .
[0016] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
