Description
Technical Field
The invention belongs to the technical field of slag and dust control, and particularly relates to a slag and dust control device and method for a garbage incinerator.
Background
The incineration disposal is one of ideal modes for realizing the resource utilization of the municipal solid waste with reduced volume and reduced weight, the incinerator mainly comprises a circulating fluidized bed, a mechanical grate furnace and the like, the grate furnace has wide application range and stable performance, and the incinerator has the most wide application in China.
The control of the garbage input in the incinerator and the thickness of the material layer on the fire grate is carried out by adjusting the garbage feeder and each section of fire grate cycle, and one action cycle of the fire grate comprises: intermediate limit-forward limit-intermediate limit-reverse limit-intermediate limit. The action period of the fire grate in the burnout section is basically unchanged, and when downstream equipment such as a slag extractor, an ash conveyor and the like breaks down and stops for a long time, the action period is prolonged to avoid ash falling into the slag extractor. The combustion condition and the material layer thickness have no direct parameter reaction, and the combustion condition is checked by mainly observing a hearth flame signal and an on-site fire observation hole by an operator. The garbage is completely combusted through the drying section, the combustion section and the burnout section, a small amount of ash falling from gaps of the fire grate is removed, the ash is sent into the slag extractor from the fire grate slag leakage conveyor through the inclined pipe, and most of slag enters the slag extractor from the burnout section through the slag falling well. Because of the common blending and burning of waste landfill waste in waste power plants in recent years and the blending and burning of primary household waste (accounting for about 30% -50%), the waste landfill waste contains a great amount of inorganic matters (such as gravels, tiles, glass, ceramics, ash, sandy soil, broken stone and the like) so as to cause the rapid increase of dust concentration above a slag falling well, and the waste landfill waste has a plurality of adverse effects on production:
(1) The fire observation holes and the hearth flame monitor probes are usually arranged on the back wall of the incinerator, the visibility of the hearth back wall is nearly zero and lasts for a period of time when slag falls, so that on one hand, operators cannot monitor the combustion condition of the hearth and make timely adjustment to influence the stability of working conditions, on the other hand, raised dust cannot monitor the hearth flame at all after the flame monitor probes are deposited to a certain degree, and the raised dust needs to be frequently and passively taken out to be manually cleaned to influence the monitoring of the working conditions of the hearth;
(2) When slag falls, a large amount of raised dust is wrapped up in a downstream (comprising waste heat utilization and flue gas purification facilities/equipment) overflow surface by flue gas, so that coking and accumulated ash blocking risks are increased, waste heat recovery rate is reduced, flue gas flow resistance is increased, flue gas deacidification reaction efficiency is reduced, boiler output is reduced, power consumption of a boiler induced draft fan is increased, and flue gas deacidification consumable and fly ash treatment and disposal costs are increased;
(3) The coking can cause local over-temperature of a heating surface, cracks caused by long-term overlarge stress can cause bursting of steam-water pipes, and the boiler is subjected to limited space operation, so that high altitude and high temperature and falling object risks exist;
(4) Coking and blockage are easy to shorten the operation period of the boiler, increase the firing and starting and stopping frequency of the boiler, increase the incomplete combustion probability of garbage, and increase the generation amount of pollutants such as CO, dioxin and the like.

The garbage incinerator adopts a mechanical fire grate, and the rear wall 4 of the incinerator corresponding to the burn-out section is provided with a burner 3 which can heat and burn unburnt garbage again; a flame monitoring probe 2 is arranged above the burner 3, so that the garbage burning condition in the hearth can be observed and monitored. The induced air control module comprises a flue baffle door 6, a flue gas pipeline 9, a variable frequency fan 10 and a block valve 11.
The flue gas pipeline 9 is lined with castable or coating, can resist high temperature, has an inlet end which is a shroud with a diameter gradually reduced, and is arranged on the rear wall 4 of the incinerator and positioned below the flame monitoring probe 2. The inlet end of the flue gas pipeline 9 is provided with a check valve 5, so that the back suction can be prevented. The flue gas pipeline 9 is provided with a flow sensor 7 which can display flow change caused by frequency adjustment of the variable frequency fan 10.
The flue baffle door 6 is arranged in the flue gas pipeline 9 and is positioned on the vertical section of the flue gas pipeline 9, so that the flue gas pipeline 9 can be prevented from being blocked by accumulated ash.
The variable-frequency fan 10 is made of wear-resistant and corrosion-resistant materials, an air inlet of the variable-frequency fan is connected with the outlet end of the flue gas pipeline 9, an air outlet pipeline is connected with a water seal of the slag dragging machine 12, and the pumping force of the variable-frequency fan is larger than the negative pressure suction force in the hearth of the incinerator.
The isolating valve 11 is arranged in an air outlet pipeline of the variable frequency fan 10 and is positioned above the water seal and used for isolating steam.
The induced air control module is started before the fire grate pushing module is started for 30-60s, namely the block valve 11 is firstly opened, the variable frequency fan 10 is operated at high speed, the flue baffle door 6 is opened, the fire grate pushing module starts a pushing period after 30-60s, and high dust-containing smoke at the tail part of the fire grate burning section is extracted to enter the water seal of the slag extractor 12; when the fire grate pushing module completes a complete pushing period, the back flue baffle door 6 is closed for 30-60 seconds, and then the variable frequency fan 10 is delayed for 30 seconds to enter an idle running state, and the isolating valve 11 is closed.
The device also comprises a pressure monitoring module of the linkage induced air control module, wherein the pressure monitoring module comprises pressure sensors respectively arranged in the hearth and the flue gas pipeline 9 and is used for monitoring and comparing the pressure in the hearth and the flue gas pipeline 9 and transmitting the comparison result to the induced air control module.
The device also comprises a slag extractor water temperature monitoring module and a slag extractor water level monitoring module which are used for controlling the water supplementing module in a linkage manner, wherein the slag extractor water temperature monitoring module is used for monitoring the water temperature in a water seal and comparing the water temperature with a set value; the slag dragging machine water level monitoring module is used for monitoring the water level in the water seal and comparing the water level with a set value; the water supplementing module is used for receiving the comparison result of the water temperature monitoring module of the slag dragging machine and the water level monitoring module of the slag dragging machine and supplementing water.
The dust control method based on the dust control device for the falling slag of the garbage incinerator comprises the following steps:
before pushing, the flue baffle door 6, the variable frequency fan 10 and the isolating valve 11 are in a closed state.
When the material is to be pushed, the induced air control module is started before the fire grate pushing module for 30-60s, namely the block valve 11 is started, the variable frequency fan 10 runs at a high speed, the flue baffle door 6 is started, and the fire grate pushing module starts a pushing period after 30-60 s. Dust-containing flue gas in the slag falls into the water seal of the slag conveyor 11 through the flue gas pipeline 9, particles in the dust-containing flue gas remain in the water seal, and cooled flue gas rises to exchange heat with high-temperature slag in the slag falling well 8 and returns to the incinerator. In the process, the opening of the flue damper door 6 is adjusted according to the data of the pressure monitoring module, so that the air pressure is adjusted to ensure that the air pressure is greater than the hearth negative pressure, and specifically: when the pressure in the hearth is smaller than the pressure in the flue gas pipeline 9, the opening of the flue baffle door 6 is reduced; when the pressure in the furnace is greater than the pressure in the flue gas duct 9, the opening of the flue damper door 6 is increased.
When the fire grate pushing module completes a complete pushing period, the back flue baffle door 6 is closed for 30-60 seconds, and then the variable frequency fan 10 is delayed for 30 seconds to enter an idle running state, and the isolating valve 11 is closed. Because tail flue gas enters under the water seal of the slag extractor 11, liquid level fluctuation, water temperature rise and water evaporation can be caused, and therefore when the water temperature monitoring module of the slag extractor monitors that the water temperature is greater than a set value, the water supplementing module supplements water. Because the fluctuation of the liquid level can cause partial water to be discharged from the overflow port, the water level monitoring is inaccurate, and therefore, after the fluctuation of the liquid level stops, when the water level monitoring module of the slag conveyor monitors that the water level is lower than a set value, the water supplementing module supplements water.
The invention can ensure the long-period safe and stable operation of the waste incineration power plant:
the coking of a waste heat utilization system and the blockage risk of a flue gas purification system can be reduced, and the availability, economy, stability and safety of a garbage power plant are improved through controlling and purifying a flue gas dust source with high dust concentration above a slag falling well 8;
the availability of the hearth flame monitoring system can be greatly improved by dust source control, which is beneficial to monitoring the combustion condition of the hearth and improving the working condition stability of the incineration power plant;
the slag falls and forms countercurrent with the smoke passing through the water seal, and the low-temperature smoke plays a role in cooling the slag, so that the cooling of the slag is enhanced; simultaneously, the temperature of the flue gas after water bath is improved;
the temperature of the extracted flue gas is higher, so that the air leakage of the slag conveyor 12 can be preheated in advance, and the influence of cold air infiltration on the burnout section at the tail part of the fire grate is relieved;
the device is simple, the control logic is simple, the investment and operation cost is low, the construction period is short, and the device is suitable for new projects or adaptive reconstruction of existing projects.
