Description

Technical Field

[0001] This utility model relates to the technical field of waste incineration power plants, and in particular to a water system for a slag discharge machine with a flushing function. Background Technology

[0002] The slag discharger system is a crucial component of power plant operation. It consists of a water-bath type boat-shaped bottom, a vertical inlet chute, and an inclined slag discharge chute. The upper suspension connects to the slag chute of the incinerator. Between the upper suspension and the outlet chute, there is a vertical water-bath wall, creating negative pressure within the furnace. Hot slag falls into the water through the slag chute and is extinguished. Scrapers push the extinguished hot residue from the bottom of the water tank towards the inclined slag discharge chute. By appropriately replenishing the water supply inside the slag discharger, sufficient water is provided to quench the slag.

[0003] Currently, the slag discharger relies on the existing fixed water supply pipe to replenish water to the inside of the slag discharger. However, due to factors such as continuous slag falling, excessive slag accumulation inside the slag discharger, excessively high water level inside the slag discharger causing impurities to submerge the water supply port, and water shortage and dust sticking to the water supply port, the water supply port of the slag discharger may be stuck with slag and impurities. The flow area at the water supply port will become smaller and smaller or even blocked, which will lead to the slag discharger being unable to replenish water normally. When the water level is lower than the normal value, there will be problems such as dry slag discharge, large dust pollution affecting the environment, abnormal negative pressure, abnormally increased induced draft fan power, and abnormally increased flue gas flow. Summary of the Invention

[0004] This utility model aims to at least partially solve one of the problems existing in the existing related technologies. To this end, this utility model proposes a slag discharge machine water circuit system with flushing function, which solves the problem of abnormal water supply to the slag discharge machine caused by slag and impurities sticking to the water inlet.

Detailed Implementation

[0024] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0025] Example 1

[0026] refer to Figure 1This embodiment provides a slag discharger water system with a flushing function, including a slag ship 1, a water inlet assembly (not shown in the figure), a flushing assembly 3, and a control assembly (not shown in the figure). A water inlet 11 is provided on the top or upper side wall of the slag ship 1. An inclined slag discharge trough 12 is formed at the end of the slag ship 1 away from the water inlet 11, and the slag discharge trough 12 has a slag discharge outlet. The water inlet assembly is connected to the water inlet 11 and forms a water supply pipeline. The water inlet assembly includes a water inlet pipe 21 and a water inlet valve (not shown in the figure). The water inlet 11 is connected to a water supply source through the water inlet pipe 21. The water inlet valve is installed on the water inlet pipe 21 to control the flow of water in the water inlet pipe 21, thereby controlling the flow of water into the slag ship 1. The flushing assembly 3 is installed on the slag ship 1. The outlet of the flushing assembly 3 is located near the water inlet 11 and is arranged towards the water inlet 11, so that the water outlet of the flushing assembly 3 faces the water inlet 11.

[0027] The control component is electrically connected to both the inlet valve and the flushing component 3. This control component controls the opening and closing of the inlet valve to control the water supply to the slag ship 1. It also controls the flushing component 3 to perform intermittent or timed flushing of the water inlet 11, removing impurities adhering to the inlet, preventing the flow area from shrinking or becoming blocked, ensuring a normal and stable water supply flow, improving the reliability of water supply to the slag discharger to a reasonable water level, effectively ensuring production safety and stable equipment operation. Simultaneously, the flushed water flows into the slag ship 1 to maintain its water seal, preventing waste. Furthermore, when the water supply pipeline has defects (such as the inlet valve failing to open) and water supply to the slag ship is impossible, the control component also controls the flushing component 2 to temporarily supply water to the slag ship 1 via the flushing component 3, thus preventing abnormal situations such as dry slag and dust emissions due to water shortage in the slag discharger.

[0028] Furthermore, the flushing assembly 3 includes a flushing water pipe 31 and a switch valve 32. The outlet of the flushing water pipe 31 is arranged facing the water inlet 11. The switch valve 32 is installed on the flushing water pipe 31 and electrically connected to the control assembly to control the flow of water through the flushing water pipe 31. When it is necessary to flush the water inlet 11 or to temporarily replenish the slag ship 1 with water through the flushing assembly 3, the control assembly controls the switch valve 32 to open for a period of time. When flushing is completed or emergency water replenishment is completed, the control assembly controls the switch valve 32 to close.

[0029] In this embodiment, the water inlet 11 is located on the upper side wall of the slag ship 1, and the flushing water pipe 31 is located above the water inlet 11. By pointing the outlet of the flushing water pipe 31 downward and adjusting the angle appropriately to align it with the water inlet 11 inside the slag ship 1, the influence of impurities sticking to the outlet of the flushing water pipe 31 can be reduced. In addition, the flushing water pressure is high and the flushing is performed regularly, which helps to ensure that the outlet of the flushing water pipe 31 is clean and free from abnormalities.

[0030] The diameter of the flushing water pipe 31 is smaller than the diameter of the inlet pipe 21. By appropriately reducing the diameter of the flushing water pipe 31, the design cost can be reduced, and the flushing water outlet pressure can be increased to enhance the flushing effect.

[0031] Furthermore, a timer (not shown in the figure) is also included. The timer is set on the switching valve 32 of the flushing assembly 3 or on the slag ship 1 and is electrically connected to the control assembly. The control assembly is used to control the flushing frequency of the flushing assembly 3 according to the timer. In this embodiment, the timer sets the timed opening time and single opening duration of the switching valve 32 in the flushing assembly 3. For example, the flushing assembly 3 flushes once every 1 hour and the single flushing duration is set to 30 seconds. In addition, when the water supply pipeline malfunctions (such as the inlet valve failing to open), and water cannot be supplied to the slag ship 1, the timer setting can be adjusted to enable temporary emergency water supply to the interior of the slag ship 1 through the flushing assembly 3.

[0032] refer to Figure 1 Furthermore, it also includes a scraper assembly 4 and / or a liquid level sensor 5. The scraper assembly 4 is movably mounted on the slag ship 1 and electrically connected to the control assembly, used to push the quenched hot residue inside the slag ship 1 toward the inclined slag discharge trough 12. In this embodiment, the scraper assembly 4 includes a scraper body, a hydraulic cylinder 41, and a transmission rod. The hydraulic cylinder 41 is located at one end of the slag ship 1 near the water inlet 11. The hydraulic cylinder 41 is connected to the scraper body via the transmission rod. The hydraulic cylinder 41 is used to drive the pressure plate body to compress the hot residue and transport the hot residue toward the edge of the slag discharge port of the slag discharge trough 12.

[0033] A liquid level sensor 5 is installed on the slag ship 1 and electrically connected to the control component. It is used to detect the liquid level in the slag ship 1. The control component can control the working status of the water inlet valve, the switching valve 32 in the flushing component 3, and the scraper component 4 according to the liquid level. When the liquid level detected by the liquid level sensor 5 is too low, the water inlet valve is opened to replenish water to the slag ship 1 to prevent dust from sticking to the water inlet port due to lack of water inside the slag discharge machine. In addition, the flushing component 3 can be controlled to flush the water inlet port 11 as needed. Conversely, when the liquid level detected by the liquid level sensor 5 is too high, the water inlet component is stopped from replenishing water to the slag ship 1, and the scraper component 4 is controlled to transport the hot residue to the edge of the slag discharge port of the slag discharge trough 12 to prevent excessive slag accumulation inside the slag discharge machine and excessive water level inside the slag discharge machine from impurities flooding the water inlet port.

[0034] Example 2

[0035] refer to Figure 2The difference between this embodiment and Embodiment 1 is that a filter element or diaphragm nozzle 6 is provided at the water inlet 11. In this case, the water outlet of the flushing assembly 3 is arranged towards the filter element or diaphragm nozzle 6. In this embodiment, the filter element is used to intercept impurities to prevent them from entering the water inlet 11. The diaphragm nozzle 6 includes at least two diaphragms 61, which can be opened by the water flow to form a spray hole 62. Thus, when the slag ship 1 does not need water replenishment, the diaphragm nozzle 6 can prevent impurities from entering the water inlet and prevent dust from sticking to the water inlet 11. When the slag ship 1 needs water replenishment, the water inlet valve is opened, and under the action of the water flow, the diaphragms in the diaphragm nozzle 6 are opened by the water flow to form a spray hole 62, thereby replenishing water to the slag ship.

[0036] Example 3

[0037] refer to Figure 3 The difference between this embodiment and embodiment 1 is that it also includes a water outlet switch 7. The water outlet switch 7 includes a baffle 71 and an elastic element 72. The baffle 71 is movably disposed at the water inlet 11 and is used to open or close the water inlet 11. The elastic element 72 can be an elastic diaphragm or a spring. It is disposed on the water inlet 11 and connected to the baffle 71. The elastic element 72 always has the tendency to close the water inlet 11 by causing the baffle 71 to close the water inlet 11.

[0038] When the slag ship 1 does not need water replenishment, the baffle 71 closes the water inlet 11 under the pre-tightening force of the elastic element 72, so that impurities or dust cannot enter the water inlet 11. When the slag ship 1 needs water replenishment, the water inlet valve is opened, and under the action of water flow, the baffle 71 is washed away from the water inlet 11 to form a gap between the baffle 71 and the water inlet 11 for water supply, so that water can be replenished to the slag ship 1.

[0039] Example 4

[0040] The difference between this embodiment and Embodiment 1 is that it also includes an outer sleeve and a power assembly. The water inlet 11 extends towards the interior of the slag ship 1, and at least one temporary water inlet hole is provided on the side wall of the water inlet 11. The outer sleeve is movably fitted onto the outside of the water inlet 11 to open or close the temporary water inlet hole. The power assembly is electrically connected to the control assembly, and the output end of the power assembly is connected to the outer sleeve, so that the power assembly drives the outer sleeve to move relative to the water inlet 11.

[0041] Under normal circumstances, the outer sleeve is in a state of blocking the temporary water supply hole, so as to hide the temporary water supply hole inside the outer sleeve, thereby preventing the temporary water supply hole from being stuck by slag and impurities. When the water supply port 11 is stuck by slag and impurities, the flow area at the water supply port becomes smaller and smaller or even blocked, which causes the slag discharge machine to be unable to supply water normally, at this time, the outer sleeve is moved to expose and open the temporary water supply hole, and the water inlet valve is opened so that the water inlet flows into the slag ship 1 through the temporary water supply hole.

[0042] Example 5

[0043] refer to Figure 4 The difference between this embodiment and Embodiment 1 is that there are two water inlets 11, which are arranged vertically at intervals. The water inlet pipe 21 includes a main water inlet section 211 and two water outlet sections 212. The outlet ends of the two water outlet sections 212 are respectively connected to the two water inlets 11. A water path switching valve 22 is provided between the outlet end of the main water inlet section 211 and the inlet end of the two water outlet sections 212. In this way, the connection state between the main water inlet section 211 and one of the water outlet sections 212 can be controlled by the water path switching valve 22, thereby realizing water path switching.

[0044] When the flow area of ​​one of the water inlets 11 becomes smaller or even blocked, the water path is switched by the water path switching valve 22 so that the water flows into the slag ship from the other water inlet 11.

[0045] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
