Description

Technical Field

[0001] The utility model relates to the technical field of sandwich bottom pots, in particular to a water temperature control system for sandwich bottom pots. Background Art

[0002] The water in the bottom-loading boiler is heated by using the heat energy of fuel or other energy sources to provide steam to the outside world, which is an important part of the steam power plant. The water is heated to a certain temperature in the heater, enters the economizer through the water supply pipe, and is sent to the boiler drum after further heating. After mixing with the boiler water, it goes down along the downcomer to the water-cooled wall inlet header. The water absorbs the radiation heat of the furnace in the water-cooled wall tube to form a steam-water mixture, which reaches the boiler drum through the riser, and the water and steam are separated by the steam-water separation device. The separated saturated steam flows from the upper part of the boiler drum to the superheater, continues to absorb heat to become 450°C superheated steam, and is then sent to the steam turbine. In terms of the combustion and smoke and wind system, the blower sends air into the air preheater to heat it to a certain temperature.

[0003] Traditional double-bottomed pots cannot be automatically controlled when heating to produce steam. They need to be manually controlled to heat or not. It is difficult to control the temperature of the water in the double-bottomed pot. Sometimes the temperature is too low to reach the required amount of steam, affecting the normal production; sometimes the temperature is too high to produce too much steam, which puts too much pressure on the double-bottomed pot and the steam pipe, which not only causes energy waste, but also poses certain safety risks.

[0021] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0022] See also Figures 1 to 4 The present embodiment provides a water temperature control system for a sandwich bottom pot, comprising a pot body 1, a pot bottom 2 and a steam pipe 3. A thermostat 105 is fixedly mounted on the outer wall of the pot body 1 for monitoring the water temperature in the pot body 1. A display 106 is mounted below the thermostat 105. The display 106 is fixedly connected to the outer wall of the pot body 1 for displaying the water temperature in the pot body 1. A solenoid valve 204 is connected in series in the circuit of the thermostat 105. The thermostat 105 controls the opening and closing of the solenoid valve 204 by monitoring the water temperature in the pot body 1. The solenoid valve 204 is connected in parallel with the display 106. When the water temperature is lower than 50°C, the thermostat 105 sends an opening command to the solenoid valve 204. When the water temperature exceeds 80°C, the thermostat 105 sends a closing command to the solenoid valve 204 to ensure that the water temperature in the pot body 1 is always between 50°C and 80°C.

[0023] The pot body 1 is provided with a pot cavity 101 for storing water for generating steam. A pot cover 102 is fixedly provided on the top of the pot body 1. The pot cover 102 bulges upward in an arc shape to gather the steam generated in the pot cavity 101 to the top of the pot cover 102, which is beneficial for the steam to enter the steam pipe 3 upward.

[0024] A water inlet 103 is fixedly provided on the top edge of the pot cover 102. The water inlet 103 passes through the pot cover 102 and is connected to the pot cavity 101. Cold water is added to the pot cavity 101 from the water inlet 103. A water inlet cover 104 is provided on the top of the water inlet 103 to separate the water inlet 103 from the outside world to prevent debris from falling into the pot cavity 101 from the water inlet 103 and contaminating the steam. The water inlet cover 104 is threadedly connected to the water inlet 103 for easy installation and disassembly.

[0025] The pot bottom 2 is fixedly arranged on the outer side of the bottom of the pot body 1. The pot bottom 2 is provided with a pot bottom cavity 201 to provide space for gas combustion. A chimney 202 is fixedly arranged on the top of the pot bottom 2. The bottom end of the chimney 202 passes through the top of the pot bottom 2 and is connected to the pot bottom cavity 201. The top end of the chimney 202 passes through the pot cover 102 and extends out of the pot body 1 to discharge the exhaust gas in the pot bottom cavity 201 and reduce the pressure of the pot bottom cavity 201.

[0026] A gas pipe 203 is fixedly provided on the side of the pot bottom 2. The gas pipe 203 passes through the side of the pot bottom 2 and is connected to the pot bottom cavity 201 to transport gas to the pot bottom cavity 201. A small hole is left at the connection between the gas pipe 203 and the side of the pot bottom 2 to provide a channel for air to enter the pot bottom cavity 201. The gas burns in the pot bottom cavity 201 under the action of the air, heating the water in the pot cavity 101 to generate steam.

[0027] A pulse igniter 205 is fixedly provided in the pot bottom cavity 201. The pulse igniter 205 is located outside the gas outlet of the gas pipe 203. A micro switch is fixedly provided in the pulse igniter 205. The micro switch is triggered when gas flows through, and the pulse igniter 205 ignites the gas.

[0028] The steam pipe 3 is fixedly provided with a safety valve 301, a pressure reducing valve 302, a No. 1 stop valve 303, a filter 304 and a No. 2 stop valve 305 in sequence from front to back. The safety valve 301 adjusts the steam pressure in the steam pipe 3. When the air pressure in the steam pipe 3 exceeds a specific value, the safety valve 301 automatically opens to discharge steam and relieve pressure. When the steam pressure drops to a specified pressure value (i.e., the return seat pressure of the safety valve), the safety valve closes automatically, so that the steam is always in a safe operation at a normal working pressure to prevent explosion caused by steam overpressure; the pressure reducing valve 302 is used to reduce the steam pressure in the steam pipe 3. The throttling of the opening and closing parts reduces the pressure at the inlet of the steam pipe 3 to an appropriate outlet pressure to ensure the stability of the pressure at the outlet of the steam pipe 3; both the No. 1 stop valve 303 and the No. 2 stop valve 305 are used to forcibly cut off the passage of the steam pipe 3. When an accident occurs, the No. 1 stop valve 303 and the No. 2 stop valve 305 are closed to forcibly block the steam pipe 3 to avoid accidents caused by steam leakage. The No. 1 stop valve 303 and the No. 2 stop valve 305 are closed at the same time to strengthen the airtightness of the steam pipe 3 and ensure that the steam does not leak; the filter 304 absorbs suspended particles in the steam to ensure that the steam is not contaminated by impurities and improve its cleanliness.

[0029] Unscrew the water filling cap 104, and fill the pot cavity 101 with cold water from the water filling port 103. When the thermostat 105 detects that the temperature of the added cold water is lower than 50°C, it sends an opening command to the solenoid valve 204, and the gas pipe 203 is unblocked to transport gas to the pot bottom cavity 201. When the gas flows through the pulse igniter 205, the micro switch in the pulse igniter 205 is triggered. The micro switch is turned on, and the pulse igniter 205 ignites, so that the gas in the pot bottom cavity 201 burns, and the cold water in the pot cavity 101 is added. As the gas continues to burn, the water temperature in the pot cavity 101 continues to rise. When the water temperature rises to 80°C, the thermostat 105 sends a closing command to the solenoid valve 204, and the gas pipe 203 is blocked, and the gas cannot be transported to the pot bottom cavity 201, and the heating of the pot cavity 101 is stopped. This cycle ensures that the water temperature in the pot cavity 101 is always between 50°C and 80°C, and a proper amount of steam is continuously generated. While increasing the gas utilization rate, safety is also guaranteed; the steam generated by hot water The steam rises upward and enters the steam pipe 3. When the air pressure in the steam pipe 3 is relatively high, the pressure reducing valve 302 reduces the pressure at the inlet of the steam pipe 3 to a suitable outlet pressure through the throttling of the opening and closing parts, thereby ensuring the stability of the pressure at the outlet of the steam pipe 3. When the air pressure in the steam pipe 3 exceeds a certain value, the safety valve 301 automatically opens to discharge the steam to relieve the pressure. When the steam pressure drops to a specified pressure value (i.e., the return seat pressure of the safety valve), the safety valve closes automatically, so that the steam is always in a safe operation under normal working pressure to prevent explosions caused by steam overpressure. When an accident occurs, the No. 1 stop valve 303 and the No. 2 stop valve 305 are closed to forcibly block the steam pipe 3 to avoid accidents caused by steam leakage. The No. 1 stop valve 303 and the No. 2 stop valve 305 are closed at the same time to strengthen the airtightness of the steam pipe 3 and ensure that the steam does not leak. Steam often contains a certain amount of suspended particles, such as dust, rust, etc. The filter 304 captures the suspended particles to ensure that the steam is not contaminated by impurities and improve its cleanliness.
