Abstract

An air draft system for preventing odor from escaping during furnace starting and stopping in a garbage incineration power plant, comprising a primary air draft system and a secondary air draft system. Due to the fact that a primary air furnace top air draft pipeline and a secondary air furnace top air draft pipeline are further provided, when the incinerator is in an off state or is in a just-started combustion state, since the hearth temperature is low, pneumatic fire dampers of the primary air draft system and and of the secondary air draft system are closed, and then the primary air furnace top air draft pipeline and the secondary air furnace top air draft pipeline are opened, and the primary air draft system and the secondary air draft system respectively draft air from the top of the furnace. Due to the fact that air above the top of the furnace is clean, the surrounding environment is not affected when flue gas is discharged into the air by means of a chimney. The flue gas discharged into the air by means of the chimney is prevented from containing an obvious odor because the temperature of the furnace is lower, effectively solving the existing technical problem.

Abstract

A method for measuring the content of heavy metal elements in household waste incineration power plant fly ash. A potion, i.e., a glacial acetic acid, is prepared at an extraction stage in the measurement process, and a tedious extractant confirmation operation is not needed; at a measurement stage, a calibration curve is drawn only once, the concentration gradient of the curve is set reasonably, and a dilution ratio of a suspected high-concentration sample can be determined before on-machine measurement; the preparation of HJ/ T 300-2007 traditional Chinese medicine can be effectively simplified; an extractant confirmation operation is not needed; and the disadvantages that many types of standard samples are needed, the concentration gradient of the calibration curve is unreasonable, the test time is long, the consumption of high-purity argon is high, the measurement is difficult, and the high-concentration waste liquid pollutes the environment in measuring the content of heavy metal in garbage power plant fly ash and a chelate thereof by HJ 781-2016 can be effectively solved. The present invention has significant advantages in the aspects such as sample testing period, material consumption, labor intensity, pollution control among samples, and measurement difficulty.

The ammonia water storage tank (1.1) is disposed in the outer ammonia water storage tank (4), and a sandwiched space (5) is arranged between the ammonia water storage tank (1.1) and the outer ammonia water storage tank (4), such that ammonia gas escaping from the ammonia water storage tank (1.1) is stored in the sandwiched space (5). An inlet end of the ammonia gas recovery pipe (6) is connected to a top portion of a tank body of the outer ammonia water storage tank (4) and is in communication with the sandwiched space (5). An outlet end of the ammonia gas recovery pipe (6) is connected to the dilution water tank (2.1), and an opening of the outlet end is located below the liquid level of dilution water. The ammonia gas escaping to the sandwiched space (5) flows into the ammonia gas recovery pipe (6) from the inlet end of the ammonia gas recovery pipe (6) and is finally dissolved in the water in the dilution water tank (2.1) to form dilution water. The invention enables recycling of escaped ammonia gas, and ensures the safety of the environment surrounding an ammonia region.

Abstract

Disclosed is a method for the online rapid calculation of a garbage incineration calorific value. The method comprises: collecting real-time temperature and humidity data and garbage fermentation time data of a garbage pool, and collecting real-time temperature data and air chamber pressure difference data of all sections of fire grates in a combustion chamber; and inputting historical data in a database into a data model formula, automatically comparing same with collected real-time data, and rapidly analyzing a garbage calorific value of a certain region by means of big data statistics and the data model formula. Under the support of rapidly analyzing a garbage calorific value, the speed of a fire grate and the opening degree of an air blower can be directly regulated and controlled, such that an optimal combustion working condition is realized, thereby ensuring that the effect of garbage incineration treatment and a pollutant emission index meet the requirements of a related national standard. After a rapid analysis is performed on a garbage calorific value, a regulation link of a garbage incinerator control system is entered in a more targeted manner, thereby improving the garbage incineration efficiency, and meeting the requirements for the decontamination, reduction and resource utilization treatment of solid waste in garbage.

Abstract

A synergistic treatment method for fly ash washing wastewater and wet-process deacidification wastewater. Chloride salts in fly ash are extracted by means of fly ash washing, then the fly ash is treated by curing using a chelating agent. After fly ash washing, the water content of a filter cake pressed by a plate and frame filter press is 40-50%, and an increase in an amount of water can increase the contact area between the chelating agent and the fly ash and improve the contact efficiency, so that the dosage of the chelating agent can be significantly reduced, and the production cost is reduced; moreover, generated fly ash washing wastewater is pumped into a deacidification wastewater pool by means of a pump and mixed with deacidification wastewater generated by a wet-process deacidification system of a waste incineration power plant, a mixed solution is conveyed to a sewage treatment facility by means of a pump, coagulation-sedimentation and evaporative crystallization processes are jointly performed to separate salts and purify water, the salts obtained by evaporation can be sold in the market, and the purified water is reused as makeup water for a fly ash washing process. Thus, the problem of enrichment of salts and heavy metals in fly ash is solved, and the goals of waste recycling and zero discharge of wastewater are achieved.

A box is provided on the unit, an incineration device and a flue gas treatment device are provided inside the box, a crusher is further provided at an inlet of an incinerator, a liquefied gas combustion-supporting device is further provided, and a combustion-supporting fan is further provided. During operation, medical waste is fed into the crusher for crushing treatment, and then enters into the incinerator to be combusted. In order to ensure smooth combustion, the combustion-supporting fan continuously supplies air into the incinerator. Flue gas generated in the incinerator enters, from a flue, the flue gas treatment device to be treated, and is then discharged from a chimney; ash residues generated after combustion are discharged downwards from an ash residue outlet at the bottom of the incinerator. The flue gas and the dust in the flue gas treatment device sequentially pass through a bag filter, a dust collection chamber, and a dust collector, and are finally discharged from an ash discharge port. Therefore, waste-minimized and environment-friendly incineration treatment for medical waste is achieved in a movable manner.
