Description

Technical Field

[0001] The utility model belongs to the technical direction of automatic temperature regulating devices, and specifically relates to automatic steam temperature regulating devices. Background Art

[0002] In industrial production, high-temperature and high-pressure steam is often generated in the process of using boilers and other combustion to provide energy. This steam has a high transmission efficiency, but due to low heat exchange efficiency and equipment pressure and temperature restrictions, it cannot be used directly. Before the equipment uses the steam, the steam must be cooled and depressurized. Therefore, due to pressure and temperature restrictions, it cannot be used directly, resulting in steam being wasted in many cases.

[0003] At present, the temperature control of steam is usually an open-loop system, and the heat exchange between steam and coolant cannot be controlled by feedback based on the outlet temperature of the steam after heat exchange. Secondly, when an accident causes the heat exchanger to shut down, high-temperature steam will be blocked at the high-temperature steam inlet. If it cannot be effectively removed, excessive accumulation will easily cause physical explosions and cause economic losses. This phenomenon has become a problem that needs to be solved urgently by people in this field. Therefore, a steam temperature automatic adjustment device is designed to automatically adjust the steam temperature and improve transmission efficiency and safety. Utility Model Content

DETAILED DESCRIPTION

[0018] The following is a further non-limiting detailed description of the technical solution of the utility model in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1 and Figure 2 The utility model provides a technical solution: a steam temperature automatic regulating device, including a steam channel 2 and a heat exchanger 3, the steam channel 2 is connected to a main channel 6, the main channel 6 is provided with a second solenoid valve 7, the main channel 6 is the main steam transmission channel, and also plays a role in assisting steam transmission, the second solenoid valve 7 is used to open and close the main channel 6.

[0020] A boiler 1 is fixedly connected to one end of the steam channel 2, and a heat exchanger 3 is fixedly connected to the other end of the steam channel 2. A first temperature sensor 4 and a first solenoid valve 5 are provided on the steam channel 2. The first temperature sensor 4 is used to measure the temperature of the steam. The first temperature sensor 4 is electrically connected to the first solenoid valve 5 and the second solenoid valve 7. The first solenoid valve 5 is used to open and close the steam channel 2.

[0021] The heat exchanger 3 is connected to a steam outlet channel 8 , the other end of which is connected to the main channel 6 . The steam outlet channel 8 is used to transmit low-temperature steam after heat exchange in the heat exchanger 3 .

[0022] The heat exchanger 3 is connected to a cooling water inlet channel 9 , through which cooling water enters the heat exchanger 3 to cool the high-temperature steam passing through the heat exchanger 3 .

[0023] The heat exchanger 3 is connected to a cooling water outlet channel 10 , and a second temperature sensor 11 is provided on the cooling water outlet channel 10 . The second temperature sensor 11 is used to measure the temperature of the cooling water after heat exchange.

[0024] A third solenoid valve 12 is provided on the cooling water outlet channel 10 , and the third solenoid valve 12 is used to open and close the cooling water outlet channel 10 .

[0025] The cooling water outlet channel 10 is connected to a cooling water circulation channel 13, and a fourth solenoid valve 14 is arranged on the cooling water circulation channel 13. The second temperature sensor 11 is electrically connected to the third solenoid valve 12 and the fourth solenoid valve 14. The fourth solenoid valve 14 is used to open and close the cooling water circulation channel 13. When the cooling water temperature measured by the second temperature sensor 11 in the cooling water outlet channel 10 is higher than the set temperature, the third solenoid valve 12 is opened and the fourth solenoid valve 14 is closed, and the cooling water is input to the boiler 1, which can reduce the heat required for converting cold water into steam in the boiler 1 and improve the utilization rate. When the cooling water temperature measured by the second temperature sensor 11 in the cooling water outlet channel 10 is lower than the set temperature, the third solenoid valve 12 is closed and the fourth solenoid valve 14 is opened, and the cooling water enters the cooling water circulation channel 13, so that the cooling water can enter the heat exchanger 3 again for heat exchange.

[0026] The heat exchanger 3 is connected to a condensate water channel 15, and the other end of the condensate water channel 15 is connected to the boiler 1. The high-temperature steam passing through the heat exchanger 3 will condense during heat exchange and cooling, generating condensate water. The condensate water is usually at a high temperature. When too much condensate water is generated, the heat exchange efficiency of the heat exchanger 3 will be affected. By setting the condensate water channel 15, the high-temperature condensate water can be discharged and reused, thereby improving the heat exchange efficiency and reducing the waste of condensate water.

[0027] It should be noted that, in order to improve the heat exchange efficiency, one or more sets of heat exchangers 3 can be connected in series (such as Figure 2 As shown in the figure, high temperature steam can be cooled down to the required temperature to improve transmission efficiency and safety.

[0028] Working principle: The high-temperature steam generated by the boiler 1 has its temperature measured by the first temperature sensor 4 on the steam channel 2. When the steam temperature is lower than the set temperature, the first solenoid valve 5 is closed and the second solenoid valve 7 is opened, and the steam is transmitted from the main channel 6 to the downstream production line; when the steam temperature is higher than the set temperature, the first solenoid valve 5 is opened and the second solenoid valve 7 is closed, and the cooling water enters the heat exchanger 3 from the cooling water inlet channel 9, and the high-temperature steam enters the heat exchanger 3 for heat exchange. After the heat exchange, the high-temperature steam enters the main channel 6 from the steam outlet channel 8 for transmission; if an accident occurs and causes the heat exchanger 3 to shut down, the first solenoid valve 5 is opened and the second solenoid valve 7 is opened, which can ensure that the generated high-temperature steam is transmitted in time to avoid safety hazards caused by blockage, thereby automatically adjusting the steam temperature and improving transmission efficiency and safety.
