Description

Technical Field

[0001] The invention relates to the technical field of boiler circulation machines for thermal power plants based on seawater desalination, and in particular to a thermal power plant boiler heat circulation machine based on seawater desalination. Background Art

[0002] Power plant boilers, also known as "power plant boilers", refer to medium and large boilers in power plants that provide a specified amount and quality of steam to steam turbines. They are one of the main thermal equipment in thermal power plants and are often matched with steam turbine generator sets of a certain capacity. They are mainly used for power generation, but in some special occasions they can also be used for external heat supply. Generally, their evaporation capacity is large, and the steam parameters (steam temperature and steam pressure) are very high. They require a complete set of auxiliary equipment, and are often equipped with chamber combustion furnaces. They use forced ventilation and can burn a variety of fuels (coal powder, crude oil or heavy oil, blast furnace gas or coke oven gas). They have a complex structure and a high efficiency, most of which can reach about 85% to 93%. They have very high requirements for operation management level, degree of mechanization and automatic control technology.

[0003] The existing Chinese patent with publication number CN111911940A includes a coal-fired coupled sludge co-combustion treatment part, a wastewater extraction part and a wastewater treatment and reuse part. The coal-fired coupled sludge co-combustion treatment part has a pre-carbonization integrated sludge disposal equipment, and the wastewater extraction part includes a power station boiler combustion evaporation equipment and a desulfurization absorption tower condensation collection equipment, which extracts the moisture increased by sludge co-combustion from the saturated flue gas at the outlet of the separation and absorption tower.

[0004] When the above-mentioned device is in use, the integrated municipal sludge treatment equipment process of pre-drying and carbonization treatment is adopted, and the complete municipal sludge water content enters the power plant for the absorption process, realizing the complete process system of sludge water content extraction, purification, concentration, fresh water recovery, brine separation and solidification, etc. However, in actual use, the evaporation used for seawater desalination in the above-mentioned comparative case, due to the fine coal powder, the coal powder will generate heat energy and high-speed airflow during the combustion process, resulting in some incompletely burned coal powder drifting away with the flue gas under the influence of the airflow, resulting in waste of resources, and easily causing uneven heating and evaporation of seawater, affecting the evaporation efficiency, so it is difficult to filter the incompletely burned coal powder in the flue gas.

[0005] To this end, we proposed a thermal cycle machine for a thermal power plant boiler based on seawater desalination. Summary of the invention

[0010] Preferably, the cleaning mechanism includes a plurality of evenly placed rectangular rods fixedly connected to the outer contour of the fixed sleeve, and each of the rectangular rods is fixedly connected to a scraper for scraping coal powder on the inner wall of the boiler body at one end away from the fixed sleeve, and the scraper is in contact with the inner wall of the boiler body.

[0011] Preferably, the rectangular rod is provided with a knocking mechanism for vibrating and dropping the coal powder on the inner wall of the boiler body, the knocking mechanism includes rectangular through grooves on the rectangular rods, each end of the rectangular rods away from the fixed sleeve penetrates through the inner wall of the rectangular through groove and is movably connected to a columnar rod for horizontal reciprocating movement, each end of the columnar rods away from the rectangular rods is fixedly connected to a knocking block for knocking on the inner wall of the boiler body, and each knocking block is fixedly connected to a reset spring on the opposite surface of the knocking block to the rectangular rod for guiding the knocking block to reset.

[0012] Preferably, the support rod is provided with an auxiliary mechanism that enables the cylindrical rod to drive the knocking block to reciprocately knock on the inner wall of the boiler body. The auxiliary mechanism includes a ring fixedly connected to the bottom side of the support rod, and a plurality of evenly placed protrusions fixedly connected to the inner wall of the ring. A connecting rod is fixedly connected to the cylindrical rod, and the end of the connecting rod is in contact with the inner wall of the ring and movably connected.

[0013] Preferably, the fixed sleeve is fixedly connected to a liquid storage tank for storing the combustion-supporting liquid, and the inner wall of the rectangular through groove of each rectangular rod close to one end of the fixed sleeve is fixedly connected to a cylindrical shell, and the symmetrical positions on both sides of each cylindrical shell close to one end of the fixed sleeve are penetrated and fixedly connected with a liquid inlet pipe and a liquid discharge pipe, and the end of the liquid inlet pipe away from the cylindrical shell penetrates through the inner wall of the liquid storage tank and is fixedly connected, and the end of the liquid discharge pipe away from the cylindrical shell penetrates through and is fixedly connected with an atomizing nozzle for atomizing and spraying the combustion-supporting liquid, and the cylindrical shell is provided with a liquid extraction mechanism for quantitatively extracting and discharging the combustion-supporting liquid in the liquid storage tank.

[0014] Preferably, the pumping mechanism includes an inner wall of a cylindrical shell, each of which is movably connected to a piston plate for extracting or discharging the combustion-supporting liquid inside the liquid storage tank, and each of the piston plates is fixedly connected to a cylindrical rod on an adjacent side.

[0015] Preferably, the inner wall of each of the liquid inlet pipes near one end of the cylindrical shell is fixedly connected to a one-way liquid inlet valve for quantitatively extracting the combustion-supporting liquid in the liquid storage tank into the cylindrical shell, and the inner wall of each of the liquid discharge pipes near one end of the cylindrical shell is fixedly connected to a one-way liquid discharge valve for quantitatively discharging the combustion-supporting liquid in the cylindrical shell into the boiler body.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Start the motor, so that the motor drives the second gear to rotate on the support rod with a fixed axis, through the first gear arranged on the rotating shaft, and the teeth on the first gear and the second gear mesh with each other, accompanied by the fixed axis rotation of the second gear, so that the first gear drives the rotating shaft to rotate synchronously on the support rod with a fixed axis under the action of the second gear, and at the same time, the sleeve drives the fan blades to rotate under the action of the rotating shaft to guide and discharge the flue gas generated by the combustion of coal powder inside the boiler body. Since the coal powder is mixed with air and burns at high temperature, heat energy and high-speed airflow are generated, so that part of the unburned coal powder floats away with the flue gas under the action of the airflow, through the filter plate arranged on the support rod, and the filter plate fits with the inner wall of the boiler body, the filter plate can filter the unburned coal powder in the flue gas, thereby avoiding the problem of unburned coal powder being discharged along with the flue gas, causing waste of resources.

[0018] Second, along with the fixed-axis rotation of the rotating shaft, the fixed sleeve drives the rectangular rod to rotate synchronously with the fixed-axis rotation under the action of the rotating shaft. Through the scraper arranged on the rectangular rod, and the scraper contacts the inner wall of the boiler body, the scraper can rotate under the action of the rectangular rod to scrape off the coal powder adhered to the inner wall of the boiler body, so that the coal powder that is not fully burned is separated from the inner wall of the boiler body and burned again, thereby ensuring the full combustion of the coal powder inside the boiler body and improving the evaporation efficiency of seawater.

[0019] 3. As the rectangular rod rotates around a fixed axis, the cylindrical rod rotates in a circle along the inner wall of the circular ring. When the cylindrical rod contacts and moves with one side of the protrusion, the cylindrical rod pulls the cylindrical rod and the knocking block under the action of the protrusion to move away from the boiler body. At this time, the reset spring is squeezed and contracted under the action of the knocking block. When the cylindrical rod moves to the other side of the protrusion and loses contact, the knocking block can move quickly toward the direction close to the boiler body and knock under the elastic force of the reset spring, thereby realizing the reciprocating knocking of the knocking block on the inner wall of the boiler body, and the boiler body vibrates under the knocking of the knocking block, thereby vibrating the unburned coal powder on the inner wall of the boiler body and improving the cleaning effect of the inner wall of the boiler body.

[0020] When the piston plate is pushed axially in the direction close to the liquid inlet pipe, the internal air pressure of the cylindrical shell near one end of the liquid inlet pipe becomes positive pressure, so that the one-way liquid inlet valve is closed and the one-way liquid discharge valve is opened, thereby the liquid inlet pipe can quantitatively extract the combustion-supporting liquid in the liquid storage tank into the interior of the cylindrical shell. When the cylindrical rod pushes the piston plate to move axially in the direction close to the liquid inlet pipe, the internal air pressure of the cylindrical shell near one end of the liquid inlet pipe becomes positive pressure, so that the one-way liquid inlet valve is closed and the one-way liquid discharge valve is opened, thereby the liquid discharge pipe can discharge the combustion-supporting liquid in the cylindrical shell into the interior of the atomizing nozzle for atomizing spraying, thereby realizing that the atomizing nozzle atomizes and sprays the combustion-supporting liquid into the flue gas, thereby enabling the combustion-supporting liquid to contact with the unburned coal powder in the flue gas and fall and burn again. At the same time, the combustion-supporting liquid can promote the further combustion of the coal powder, thereby improving the combustion efficiency and heat transfer efficiency of the coal powder.

[0021] The coordinated use of the above-mentioned structure solves the problem that in the actual use of the existing device, due to the fine coal powder, the coal powder will generate heat energy and high-speed airflow during the combustion process, causing some unburned coal powder to float away with the flue gas under the influence of the airflow, resulting in waste of resources, and easily causing uneven heating and evaporation of seawater, affecting the evaporation efficiency, and therefore it is difficult to filter the unburned coal powder in the flue gas.

[0042] The cleaning mechanism includes a plurality of evenly placed rectangular rods 9 fixedly connected to the outer contour of a fixed sleeve 8, and a scraper 10 for scraping coal powder from the inner wall of the boiler body 1 is fixedly connected at one end of each rectangular rod 9 away from the fixed sleeve 8, and the scraper 10 is in contact with the inner wall of the boiler body 1.

[0043] When in use, the fixed sleeve 8 provided on the rotating shaft 3 and the rectangular rod 9 provided on the fixed sleeve 8 rotate along with the rotating shaft 3, so that the fixed sleeve 8 drives the rectangular rod 9 to rotate synchronously with the rotating shaft 3, and the scraper 10 provided on the rectangular rod 9 is in contact with the inner wall of the boiler body 1, so that the scraper 10 can rotate under the action of the rectangular rod 9 to scrape off the coal powder adhered to the inner wall of the boiler body 1, so that the coal powder that is not fully burned is separated from the inner wall of the boiler body 1 and burned again, thereby ensuring that the coal powder inside the boiler body 1 is fully burned, and improving the evaporation efficiency of seawater.

[0044] Embodiment three:

[0045] See also Figures 3 to 7 On the basis of the second embodiment, further:

[0046] The rectangular rod 9 is provided with a knocking mechanism for vibrating and dropping the coal powder on the inner wall of the boiler body 1. The knocking mechanism includes rectangular through grooves 901 opened on the rectangular rod 9, and each end of the rectangular rod 9 away from the fixed sleeve 8 penetrates through the inner wall of the rectangular through groove 901 and is movably connected to a columnar rod 11 for horizontal reciprocating movement, and each end of the columnar rod 11 away from the rectangular rod 9 is fixedly connected to a knocking block 12 for knocking the inner wall of the boiler body 1, and each knocking block 12 is fixedly connected to the opposite surface of the rectangular rod 9 with a reset spring 13 for guiding the knocking block 12 to reset.

[0047] The support rod 2 is provided with an auxiliary mechanism that enables the cylindrical rod 11 to drive the knocking block 12 to reciprocately knock on the inner wall of the boiler body 1. The auxiliary mechanism includes a circular ring 15 fixedly connected to the bottom side of the support rod 2, and a plurality of evenly placed protrusions 16 are fixedly connected to the inner wall of the circular ring 15.

[0050] Embodiment 4:

[0051] See also Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 On the basis of the third embodiment, further:

[0052] The fixed sleeve 8 is fixedly connected to a liquid storage tank 17 for storing the combustion-supporting liquid, and the inner wall of the rectangular through groove 901 of each rectangular rod 9 near one end of the fixed sleeve 8 is fixedly connected to a cylindrical shell 18, and the symmetrical positions on both sides of each cylindrical shell 18 near one end of the fixed sleeve 8 are penetrated and fixedly connected with a liquid inlet pipe 19 and a liquid discharge pipe 20, and the end of the liquid inlet pipe 19 away from the cylindrical shell 18 is penetrated to the inner wall of the liquid storage tank 17 and fixedly connected, and the end of the liquid discharge pipe 20 away from the cylindrical shell 18 is penetrated and fixedly connected with an atomizing nozzle 21 for atomizing and spraying the combustion-supporting liquid, and the cylindrical shell 18 is provided with a liquid extraction mechanism for quantitatively extracting and discharging the combustion-supporting liquid in the liquid storage tank 17.

[0053] Through the liquid storage box 17 arranged on the fixed sleeve 8, the combustion-supporting liquid is first stored in the liquid storage box 17, and through the cylindrical shell 18 arranged on the rectangular rod 9 and the liquid inlet pipe 19 arranged on the cylindrical shell 18, the liquid inlet pipe 19 connects the liquid storage box 17 with the cylindrical shell 18, so that the combustion-supporting liquid in the liquid storage box 17 enters the interior of the cylindrical shell 18, and through the drain pipe 20 arranged on the cylindrical shell 18 and the atomizing nozzle 21 arranged on the drain pipe 20, the drain pipe 20 can connect the cylindrical shell 18 with the atomizing nozzle 21, and through the pumping mechanism arranged on the cylindrical shell 18, the pumping mechanism can quantitatively extract the water source in the liquid storage box 17 and spray it into the boiler body 1.

[0054] Embodiment five:

[0055] See also Figures 7 to 9 On the basis of the fourth embodiment, further:

[0056] The pumping mechanism includes a cylindrical shell 18 whose inner wall is movably connected to a piston plate 24 for extracting or discharging the combustion-supporting liquid in the liquid storage box 17. Each piston plate 24 is fixedly connected to the cylindrical rod 11 on an adjacent side.

[0057] Each of the liquid inlet pipes 19 has an inner wall near one end of the cylindrical shell 18 fixedly connected to a one-way liquid inlet valve 22 for quantitatively extracting the combustion-supporting liquid in the liquid storage tank 17 into the cylindrical shell 18, and each of the liquid discharge pipes 20 has an inner wall near one end of the cylindrical shell 18 fixedly connected to a one-way liquid discharge valve 23 for quantitatively discharging the combustion-supporting liquid in the cylindrical shell 18 into the boiler body 1.

[0058] When in use, through the piston plate 24 set on the cylindrical shell 18, the piston plate 24 is fixedly connected to the cylindrical rod 11. When the cylindrical rod 11 drives the knocking block 12 to knock back and forth on the inner wall of the boiler body 1, the piston plate 24 moves axially back and forth along the inner wall of the cylindrical shell 18 under the action of the cylindrical rod 11.

[0059] Through the one-way inlet valve 22 and the one-way discharge valve 23 provided on the inlet pipe 19 and the discharge pipe 20, when the cylindrical rod 11 pulls the piston plate 24 to move in the direction away from the inlet pipe 19, the internal air pressure of the cylindrical shell 18 close to the inlet pipe 19 is negative pressure. At this time, the one-way inlet valve 22 is in an open state, and the one-way discharge valve 23 is in a closed state, so that the inlet pipe 19 can quantitatively extract the combustion-supporting liquid in the storage tank 17 into the interior of the cylindrical shell 18. When the cylindrical rod 11 pushes the piston plate 24 to move in the direction close to the inlet pipe 19, the internal air pressure of the cylindrical shell 18 is negative pressure. At this time, the one-way inlet valve 22 is in an open state, and the one-way discharge valve 23 is in a closed state. When it moves, the internal air pressure of the cylindrical shell 18 near one end of the liquid inlet pipe 19 is positive, so that the one-way liquid inlet valve 22 is in a closed state and the one-way liquid discharge valve 23 is in an open state, and then the liquid discharge pipe 20 can discharge the combustion-supporting liquid inside the cylindrical shell 18 into the atomizing nozzle 21 for atomized spraying, so that the atomizing nozzle 21 atomizes and sprays the combustion-supporting liquid into the flue gas, so that the combustion-supporting liquid can contact with the unburned coal powder in the flue gas and fall and burn again. At the same time, the combustion-supporting liquid can promote the further combustion of the coal powder, thereby improving the combustion efficiency and heat transfer efficiency of the coal powder.

[0060] As the rectangular rod 9 drives the cylindrical shell 18 to rotate along a fixed axis, the liquid pumping mechanism can evenly spray the combustion-supporting liquid into the interior of the boiler body 1, thereby improving the contact between the combustion-supporting liquid and the unburned coal powder in the flue gas.

[0061] Furthermore, the existing device can filter the incompletely burned coal powder in the flue gas during actual use, thereby improving the combustion efficiency and heat transfer efficiency of the coal powder, being easy to use and being better than traditional products.

At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
