Description

Waste incinerator lower water tank trash cleaning device, deslagging system and deslagging method

Technical Field

The invention relates to a waste incinerator lower water tank cleaning technology, in particular to a waste incinerator lower water tank cleaning device, a slag removing system and a slag removing method.

Background

In a garbage incinerator system, in order to collect ash slag generated after garbage combustion, a furnace bottom ash conveyor (or called an under-furnace ash conveyor, hereinafter called an ash conveyor for short) is arranged at the lower side of a fire grate, and a slag extractor (or called a slag extractor) is arranged at the tail end of the fire grate. Both are located at the bottom of the grate, except that the former is located at the underside of the grate and the latter is located at the underside of the end. The furnace bottom ash conveyer is arranged below the fire grate and is used for receiving ash slag or garbage falling from the fire grate grid in the garbage combustion process and conveying the ash slag or garbage into a slag pool or a slag box groove; and the slag extractor is arranged at the tail end of the fire grate and used for receiving ash generated by burning the garbage and discharging the ash into the slag pool.

The slag extractor and the furnace bottom ash conveyer are two independent devices, each independently operates and the waterways are not communicated with each other, and the slag extractor and the furnace bottom ash conveyer have the following common points:

Firstly, the slag is received through a slag drop port at the top;

secondly, the ash residue conveying device is provided with a tank and is used for conveying ash residues;

thirdly, water is required to be stored in the tank, and the water level reaches the position of the slag falling port, so that the slag falling port is sealed by water;

Fourthly, because the garbage will absorb water after falling into the water, the garbage is discharged and then takes away the water, so that the water is continuously lost in the tank, intermittent water supplement is needed for maintaining the stable water level, and the water level monitoring element is not suitable to be installed in the tank because the water is rocked due to the operation of the conveying equipment, therefore, the water supplementing tanks are needed to be arranged beside the tank of the two and matched with the automatic water supplementing device, and the water supplementing tanks are communicated with the water channel formed by the tank through the communicating pipe. The two water replenishing tanks are replenished with water through respective automatic water replenishing devices so as to indirectly replenish water for the tank.

In actual production operation, due to the complex components of the garbage, ash which can be partially dissolved in water exists after the garbage burns, and particularly, due to scraping and grinding of the garbage caused by the operation of conveying equipment, a large amount of powdery substances are generated, so that the water quality in a slag extractor or a furnace bottom ash conveyer tank is extremely dirty. Because the tank is communicated with the water supplementing groove, a part of the pollutant in the tank reversely flows into the water supplementing groove through the communicating pipe, so that the water quality of the water supplementing groove is poor. The tank bottom of the water supplementing tank often accumulates a large amount of sludge and causes the blocking of the communicating pipe; in addition, suspended matters in water and scum on the water surface are easy to form scale on the surface of the water level monitoring element, and finally the normal water replenishing of the water replenishing device is influenced.

Therefore, the maintainer needs to go to the site to patrol and salvage the scum in time; however, as equipment of the electric garbage incineration power plant needs to continuously run, the water supplementing tank cannot be emptied and cleared in the running process, so that sludge in the tank is accumulated for a long time, and finally a communicating pipe is blocked, thereby affecting the normal running of the garbage incineration power plant.

On the other hand, in the operation process of the ash conveyer, because the working liquid level of the ash conveyer tank is positioned at the neck position of the ash dropping mouth, the garbage and ash dropping from the ash bucket are easy to accumulate at the ash dropping mouth after forming scum, and the ash dropping mouth is in a closed state with the outside, so that the work difficulty of checking and cleaning is very high. And the scum is accumulated at the ash drop port for a long time and is easy to form scale formation, and finally, the ash blocking phenomenon (the ash blocking phenomenon is that scale formation is formed due to the ash drop port, and ash slag forms scale formation to cause that garbage and ash slag cannot fall into an ash conveying machine box groove, and accumulated ash slag is more and more finally directly arranged on an upper grate), so that primary air cannot enter, and the normal operation of a garbage incineration system is seriously influenced.

The volume reduction rate of the garbage combustion can reach two thirds, so the quantity of slag (ash slag) falling into the slag box groove 2 is huge. Meanwhile, in the process of moving and rolling garbage on the fire grate 1, small garbage or burnt small ash slag on the fire grate falls down through the fire grate (primary air continuously flows upwards from the bottom of the fire grate to enter a hearth at the upper part through the grid holes) and falls into a tank groove of the furnace bottom ash conveyer through an ash bucket. Water is stored in the slag discharging machine box groove 2 and the ash conveying machine box groove 3, and the water in the machine box grooves can realize water sealing between the hearth and the outside on one hand and can cool the fallen slag on the other hand. The conveying devices in the slag box groove and the ash conveying box groove are responsible for conveying the furnace groove in the groove to the slag pool.

Since ash will absorb a part of water after falling into water, and then be transported to the slag extractor or slag pool at the end of the fire grate to take away a part of water, the water in the slag extractor or ash conveyor is continuously lost, and automatic water supplementing devices 2.3 and 3.3 (usually automatic water supplementing devices of float valves) are required to maintain the stability of the water level in the slag extractor or ash conveyor. However, the sludge and the scum in the tank part enter the water supplementing tanks (such as 2.1 and 3.1) through the communicating pipes (such as 2.11 and 3.11), and the water supplementing tanks cannot be emptied and cleaned in the daily operation process. Therefore, sludge is continuously accumulated in the tank bottom of the water supplementing tank, the liquid level of the water supplementing tank is also continuously floated and scum is accumulated, and when the water level is serious, the communicating pipeline is blocked, the surface of a water level monitoring element (such as a floating ball or an electronic liquid level meter) is scaled, so that the normal operation of the automatic water supplementing devices 2.3 and 3.3 is influenced, and the normal operation of a garbage incineration system is seriously influenced.

At present, the scum on the liquid surface of the water supplementing tank is usually removed by adopting a manual salvaging method, but the sludge at the tank bottom cannot be treated.

It should be noted that fig. 1-6 are mainly schematic structural views of the existing garbage incinerator system in terms of functional aspects, and do not represent the actual structure of the prior art in terms of details.

Fig. 7 to 18 are schematic structural views of a first embodiment of the present invention. This example is the trash cleaning device of slag extractor moisturizing groove. In this example, the cleaning device includes a water compensating tank 2.1 and a first automatic water compensating device 2.3, and further includes a communicating pipe 2.11 connected between the slag box tank 2 and the water compensating tank 2.1.

In the example, the first automatic water supplementing device 2.3 is controlled to be opened or closed by a float valve 2.35; the water level monitoring element (floating ball) of the first automatic water supplementing device is arranged in the water supplementing groove 2.1, and the first automatic water supplementing device 2.3 supplements water to the water supplementing groove 2.1.

In this example, a drain pipe 6 and a drain pump 7 are further disposed, an inlet 6A1 (hereinafter referred to simply as an inlet) of the drain pipe 6 is located at a bottom of the trough cavity of the water replenishing trough 2.1, and an outlet 6B1 (hereinafter referred to simply as an outlet) of the drain pipe 6 is connected to the slag box trough 2 or the slag pool.

When the sewage is discharged, the drainage pump is started and the running time is set, and as the inlet of the drainage pump 7 is arranged at the bottom of the tank cavity, the sludge and sewage at the bottom of the tank are continuously drained. In the process of starting the drain pump, the first automatic water replenishing device 2.3 starts water replenishing due to the fact that the water level of the water replenishing tank drops. In this example, the drain pump 7 is used to drain the sludge and sewage at the bottom of the tank into the slag box or the slag pool, so that the continuous deposition of the sludge in the water supplementing tank can be reduced, and the water in the water supplementing tank is continuously supplemented by the first automatic water supplementing device 2.3, so that the cleanliness of the water in the water supplementing tank is further improved.

The invention prompts that the water is lost more in the normal operation process of the slag extractor, the daily water supplementing amount is larger (usually, the daily water supplementing amount is needed to be several tons or more, and the daily treatment amount of the garbage is different), and the tank bottom sludge and sewage of the water supplementing tank are discharged into the tank of the slag extractor, so that the sewage of the water supplementing tank can be cleaned, the sewage can be recycled on the premise that the normal operation of the slag extractor is not influenced, and the water resource waste is reduced.

In order to drain the water replenishing tank during the sewage draining process, so as to further improve the sewage cleaning effect of the water replenishing tank, in the preferred embodiment, a hose 2.111 is further connected to the pipe orifice of the communicating pipe 2.11 located in the water replenishing tank, the hose 2.111 is used as an extension pipe of the communicating pipe 2.11, and a driving assembly is further provided, and the pipe orifice of the hose 2.111 is driven by the driving assembly to rise away from the working liquid level or descend to sink below the working liquid level. The purpose of the hose 2.111 is to raise the mouth of the hose 2.111 above the working liquid level and then empty the make-up tank.

In this example, the driving assembly includes a rotating rod 8.1 (or a rotating arm and a rotating frame), a pipe orifice member 8.2 is further disposed at the pipe orifice of the hose 2.111, the pipe orifice member 8.2 is in a circular pipe structure, one end of the pipe orifice member 8.2 is inserted and fixed on the pipe orifice of the hose 2.111, and the other end of the pipe orifice member 8.2 is connected with the rotating rod 8.1 through a pin shaft.

In this example, the rotating rod 8.1 is a square frame structure formed by bending round steel, and one end of the rotating rod 8.1 is installed in the shaft hole 8.51 of the fixing seat 8.5 so that the rotating rod 8.1 can rotate around the shaft. The pipe orifice 8.2 is provided with a shaft hole 8.21 (the central line of the shaft hole 8.21 is perpendicularly connected with the central line of a circular pipe of the pipe orifice 8.2), and the pipe orifice 8.2 is arranged at the other end of the rotary rod 8.1 through the shaft hole 8.21 so that the pipe orifice 8.2 and the rotary rod 8.1 form pin shaft connection.

In this example, drive assembly still includes electric putter 8.3, still sets up notch first support 8.42, and notch first support 8.42 is bent by the sheetmetal and is formed, and notch first support 8.42 is installed on the notch of moisturizing groove 2.1. The electric push rod 8.3 is arranged on the lower side of the notch first bracket 8.42, and the electric push rod 8.3 drives the rotating rod 8.1 to rotate so as to drive the pipe orifice piece 8.2 to rise to the working liquid level above 2.01 or fall to the working liquid level below.

In this example, the flow rate of the drain pump 7 exceeds the flow rate of the first automatic water replenishment device 2.3 (the flow rate of the drain pump 7 exceeds the flow rate of the first automatic water replenishment device 2.3 so that the water replenishment tank can be emptied).

In this example, an electronic level gauge 2.23 is also provided;

under the normal operation condition, the pipe orifice of the hose 2.111 is positioned below the working liquid level so as to enable the water supplementing groove and the tank to form waterway communication, when the tank 2 is lowered in water level due to water loss, the first automatic water supplementing device 2.3 supplements water to the water supplementing groove 2.1, and the water flows into the tank through the hose 2.111 and the communicating pipe 2.11 in sequence so as to maintain the stable water level of the tank;

When sewage is required to be discharged, the driving assembly is started to lift the pipe orifice of the hose 2.111 to be more than 2.01 of the working liquid level, then the drainage pump 7 is started to discharge sewage, and tank bottom sludge and sewage are discharged into a tank or a slag pool through the drainage pipe 6 until the water supplementing tank is emptied. In the sewage discharging process, the pipe orifice of the hose 2.111 is lifted to be above the working liquid level 2.01, so that sewage in the tank 2 cannot reversely flow into the water supplementing tank 2.1; the invention suggests that the pipe orifice of the hose 2.111 is lifted to be higher than the working liquid level 2.01, and then the drainage pump is started for drainage, and a time gap can be set to realize sequencing, for example, the drainage pump 7 is started after 15 seconds after the electric push rod 8.3 is started.

In the sewage draining process, the first automatic water supplementing device 2.3 continuously supplements water to the water supplementing groove 2.1.

In the state of blowdown, when the electronic level meter 2.23 monitors that the water replenishing tank is emptied or the drainage pump 7 is operated for a set time, the drainage pump 7 is closed. After the water level of the water replenishing tank 2.1 gradually rises and returns to the normal working level, when the water level of the water replenishing tank is at the normal working level from the time of closing the drainage pump 7 to the time of setting or the time of monitoring by the electronic level meter 2.23, the driving assembly is started again to drive the pipe orifice piece 8.2 to descend below the working level.

In the embodiment, the water supplementing tank is emptied and supplemented with water at regular intervals, so that sludge in the tank can be effectively removed, the water quality is ensured to be clean, and scaling is prevented from forming on the surface of the water level monitoring element; meanwhile, the sludge can be prevented from depositing and accumulating at the bottom of the tank, and the orifice of the communicating pipe is prevented from being blocked.

The invention suggests that the normal operating level comprises a low level value and a high level value (hereinafter referred to as the low level value and the high level value), the level between the low level value and the high level value both belonging to the normal operating level; the water replenishing starting liquid level of the first automatic water replenishing device is higher than or equal to the low level value, and the safety warning line of the liquid level of the system is higher than the high level value.

Fig. 48 to 50 are schematic structural views of an eighth embodiment of the present invention.

The plant had a total of 1 incinerator of this model, as in the configuration of the seventh embodiment. Different, in this example, each ash dropping port of each ash conveyer is additionally provided with a set of trash cleaning device respectively. Thus, the slag removal system configured by the factory comprises 20 sets of the cleaning device and 5 cameras, and the control device of the system controls the operation of the 20 sets of the cleaning device and the 5 cameras;

In this example, the slag box groove 2A is connected to slag liquid discharged by 10 sets of the cleaning device, and the slag box groove 2B is connected to slag liquid discharged by 10 sets of the cleaning device.

Preferably, in order to facilitate the connection of the drain pipe of the sewage disposal device and the slag notch of the slag notch box and facilitate the pipe arrangement, in the example, a header 15A is further arranged on the upper cover of the slag notch box 2A, the header 15A comprises a pipe body 15A.1, the pipe body 15A.1 is vertically arranged, the pipe cavity of the pipe body 15A.1 is communicated with the notch cavity of the slag notch box 2A, 10 connecting nozzles 15.2 are arranged on the pipe body 15A.1, and the outlets of the drain pipe of the 10 sets of sewage disposal devices are respectively connected to 10 connecting nozzles 15.2 of the header 15A.

The invention also needs to be described, namely a set of sewage disposal device which is provided with at least a sewage discharge pipe and a drainage pump and can independently complete the sewage discharge function under the control of a system. For example, a cleaning device configured for a slag extractor water supply tank or a cleaning device configured for a slag conveyor water supply tank can finish sludge and sewage pollution discharge of the water supply tank, and can be called a set of cleaning device; or a dirt cleaning device which is configured for a dust falling port of a dust conveying machine box groove and can finish the slag removal of the liquid level of the dust falling port, and the dirt cleaning device can also be called a set of dirt cleaning device.

Examples of the deslagging method of the invention

The maintainer utilizes the control device and the programmable controller of the deslagging system, and the sewage disposal device under the setting system automatically operates according to the set mode, and comprises the following two situations:

The sewage disposal device is set to be started for sewage disposal once at each DeltaT ₁.

As in example a, Δt1 was set to 8 hours, and the cleaning apparatus was turned on for discharge every 8 hours.

The invention prompts that if the sewage disposal device is applied to the water supplementing tank, the control of the primary sewage disposal process can be realized by setting the running time of the drain pump or can be realized by sending a signal by the electronic liquid level meter; when the draining is realized by setting the running time, the draining time node of the water supplementing groove is positioned before the draining pump is closed; when the draining pump is realized by sending a signal through the electronic liquid level meter, and the electronic liquid level meter sends the liquid level information of the draining tank when the draining pump is emptied to the control device, the control device controls the draining pump to be closed immediately or to be closed after maintaining the draining for a period of time.

If the cleaning device is applied to the ash drop port, the operation time of the drain pump can be set and the time node for emptying the overflow cavity can be ensured to be positioned before the drain pump is closed for controlling the one-time sewage discharging process.

As in embodiment B, if the decontamination apparatus is applied to the water replenishment tank, one way is: the operation time of the drain pump in the primary sewage draining process is set to be 1 minute, the drain pump is closed after being operated for 1 minute in the sewage draining process, and the time node for draining the water supplementing groove is positioned before the drain pump is closed. Another way is: when the electronic liquid level meter sends the liquid level information of the water replenishing tank during emptying to the control device, the control device controls the drainage pump to be closed immediately or to be closed again after the draining is maintained for 10 seconds (namely, delayed for 10 seconds).

If the cleaning device is applied to the ash falling port of the ash conveyer, the running time of the drainage pump is set to be 1 minute in one sewage discharging process, and the time node for emptying the overflow cavity is positioned before the drainage pump is closed.

The invention prompts that the setting of the running time of the drainage pump should be adjusted according to the actual situation.

Taking all sets of dirt cleaning devices discharged into the same slag box groove as a group, or taking the dirt cleaning devices discharged into all ash falling openings of the same ash conveying box groove of a slag pool as a group; the sewage is discharged once every delta T2 in one group and the sewage of each set of sewage disposal devices is alternately performed one by one (namely, only one set of sewage disposal devices is allowed to be started at the same time).

As in embodiment C, referring to the arrangement of the cleaning device of the eighth embodiment, the way of discharging the slag liquid is described.

1 Incinerator in a certain factory, 2 slag discharging machines and 3 ash conveying machines matched with the incinerator, wherein each slag discharging machine and each ash conveying machine are respectively provided with a water supplementing tank, and each ash conveying machine is provided with 5 ash falling ports; if a set of cleaning device is provided for each water supplementing tank and each ash falling port, the plant needs 20 sets of cleaning devices in total, and slag liquid of the cleaning devices is completely discharged into two slag box grooves 2A and 2B. Then 10 sets of decontamination devices connected with one slag discharging machine box groove are used as one group, and the total number of the groups is 2 in this example. In this example, Δt2 is set to 1 hour. The sewage disposal device is started every 1 hour in one group, and the sewage disposal of each set of sewage disposal devices is performed one by one in turn, namely, the sewage disposal of any set of sewage disposal devices is performed every 10 hours. In this example, the time of operation of the drain pump in the primary drainage process of the water replenishing tank and the ash dropping port is set to be 1 minute, that is, the automatic operation mode is as follows:

First cycle: the first dirt cleaning device is started for 1 minute to be closed, the second dirt cleaning device is started from the first starting time, and the second dirt cleaning device is started for 1 minute after 1 hour; starting the timing from the starting time of the third step, and starting the first step for 1 minute after 2 hours; starting the timer from the first starting time to the tenth starting time, and starting the timer for 1 minute after 9 hours;

then a second cycle is started: the first step is started for 1 minute after 10 hours from the starting time; the second dirt cleaning device counts from the last starting time of the first dirt cleaning device, and is started for 1 minute after 1 hour; … …, thus cycling continuously; any set of the cleaning device is turned on for 1 minute one by one in turn every 10 hours.

The automatic operation mode of the other 10 sets of the cleaning devices connected with the slag discharging machine box groove 2B can also be set according to the mode.

In this example, the decontamination device of the deslagging system of the factory comprises two groups, each group comprises 10 sets of decontamination devices, and the control device of the deslagging system controls the automatic operation of the two sets of decontamination devices.

In this case, the emptying time of the water replenishing tank and the ash drop port overflow cavity should be less than 1 minute, i.e. the time nodes of the water replenishing tank and the ash drop port overflow cavity are all located before the drain pump is closed. In specific implementation, the operation time of the draining pump of the water supplementing groove and the ash falling port is respectively adjusted according to the draining time of the water supplementing groove and the ash falling port overflow cavity.
