Incinerator for urban refuse granular fuel

Abstract

The invention relates to a intelligent burning furnace for burning city particle waste, which comprises a furnace, a base, a furnace bed, a material feeder, a material outlet, a ignite system, the first wind feeder, the second wind feeder, and an automatic control system. Said furnace comprises connected first, second and third burning rooms and a wind distribution room; each burning room is relative to the preheating, crack gasify reaction, solid firing, and gas burning; the first and second burning rooms are independently mounted with first and second furnace bed; the smoke feeding channel of second wind inlet system is through to the wind distribution room and inside the furnace wall; the automatic control system comprises a controller connected to the digital / analogue converter connected of each executer, a signal collector connected to the controller, and a driving circuit. The invention can fully burn waste, utilize left heat, without adding combustion supporter, and it can reduce the energy consumption and cost, to confirm the tail gas reach discharge standard.

Description

technical field [0001] The invention relates to an incinerator for treating municipal domestic waste made into granular fuel. Background technique [0002] At present, the treatment of municipal solid waste is developing in the direction of pollution-free resources. Waste incineration power generation is an ideal method of waste treatment. The existing incinerators are divided into two categories according to their working principles: solid-phase substances are fully ignited and self-immolated. waste incinerators and pyrolysis gasification waste incinerators that degrade polymers into flammable gases (such as: CO, CxHy, CH4, H2, etc.) The objects are all unsorted or simply sorted domestic garbage; the solid-phase material is fully ignited and self-ignited. The garbage incinerator mainly has the following two structures: [0003] (1) Vertical garbage incinerator: It adopts a vertical cupola structure, but only adds fuel injection devices and temperature monitoring devices to...

AI Technical Summary

Problems solved by technology

[0011] The fluidized bed incinerator has the advantages of smaller furnace body, low thermal ignition loss rate of incineration slag (about 1%), less movable parts in the furnace, and more sufficient combustion. However, compared with mechanical grate furnace, it has the following advantages: Disadvantages: ① More coordinated flow sand circulation system than mechanical grate furnace, and the wear caused by flow sand is greater, and the service life of the incinerator is shorter; ② The balance of combustion air is difficult, and CO is easier to produce, and CO in flue gas In order to maintain a more suitable temperature for burning various wastes, the air temperature of the air volume must be adjusted; ③ It is difficult to control the temperature in the furnace, and the incineration quality is unstable

[0012] The advantage of the fluidized bed incinerator is to keep the flowing sand at a certain temperature, so it is convenient to start and stop the furnace every day, but the current trend is to try to ensure the continuous operation of the incinerator without the need to stop the furnace every day, so that the fluidization cannot be reflected Fluidized bed incinerators are rarely used in new waste incineration plants recently
