Abstract
The utility model discloses a novel waste incinerator's preheated air system, including high temperature flue gas production equipment, the primary air of high temperature flue gas production equipment production directly passes through pipe connection waste incinerator, secondary air that high temperature flue gas production equipment produced and the air mixing who comes from dump pit, and the mist burns burning furnace through the pipe connection, and burning furnace is burnt in the connection of a plurality of air outlets of primary air pipeline share, just connects with it from the bottom of burning burning furnace, mixes air conduit and connects with it from burning the burning furnace top. The utility model discloses a waste heat air piping system has cancelled boiler air heater and steam - air heat exchanger, make full use of industrial production and gas turbine's high temperature flue gas waste heat, can save the inside superheated steam who receives hot side and production of boiler, receive the hot side if mate the waste incinerator afterbody again, strengthen the boiler capacity, can improve the whole heat economy nature of power plant.
Description
Technical field
The utility model relates to a kind of pre-heating system of incinerator.
Background technology
As shown in Figure 1, the top of trash repository is provided with extract system to the air flow process of traditional incinerator, and its air extracted out sends into air blast 11, after air blast 11 supercharging, then delivers to steam-air heat exchanger 12 and heats; Air after heating is divided into primary and secondary air, and Secondary Air directly sends into burner hearth, garbage drying, and remaining First air is sent into boiler air preheater 13 and carried out post bake, sends into incinerator 14 after improving temperature further, participates in burning.The high-temperature flue gas that burning produces contacts with burner hearth internal heating surface, and make water become superheated steam for generating, flue gas flows through tail air preheater, after adding heat primary air, by flue gas purification system, enters air after up to standard.Whole system operation is longer, and equipment is more, adds a lot of cost.
Utility model content
The purpose of this utility model is to provide the preheated air system of the simple incinerator of a kind of structure, utilizes hot industry flue gas for waste incineration, reclaims the waste heat of high-temperature flue gas.
The technical solution of the utility model is as follows: a kind of preheated air system of refuse incinerator, comprise high-temperature flue gas and produce equipment, the primary air that high-temperature flue gas produces equipment generation directly connects incinerator by pipeline, the auxiliary air that high-temperature flue gas produces equipment generation mixes with the air from dump pit, mist connects incinerator by pipeline, primary air pipeline is divided into multiple air outlet and connects incinerator, and be attached thereto from the bottom of incinerator, mixing air pipeline is attached thereto from incinerator top.
Described primary air pipeline diminishes at the caliber near incinerator place.
Described high-temperature flue gas produces equipment and is replaced by gas turbine, and the primary air that gas turbine produces and auxiliary air enter primary air pipeline and auxiliary air pipeline respectively.
Preheated air system of the present utility model eliminates boiler air preheater and steam-air heat exchanger, take full advantage of the high-temperature flue gas waste heat of industrial production and gas turbine, the superheated steam of boiler internal heating surface and generation can be saved, if again mate incinerator back-end surfaces, strengthen boiler capacity, the overall thermal economy of power plant can be improved.Gas turbine and waste incineration cogeneration, effectively can utilize the smoke discharging residual heat of gas turbine, improves the thermal efficiency of power plant.
Accompanying drawing explanation
Fig. 1 is the structural representation of traditional preheated air system.
Fig. 2 is structural representation one of the present utility model.
Fig. 3 is structural representation two of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 2, a kind of preheated air system of refuse incinerator, comprise high-temperature flue gas and produce equipment 1, the primary air that high-temperature flue gas produces equipment 1 generation directly connects incinerator 2 by pipeline, the auxiliary air that high-temperature flue gas produces equipment 1 generation mixes with the air from dump pit, mist connects incinerator 2 by pipeline, primary air pipeline 3 is divided into multiple air outlet and connects incinerator, and be attached thereto from the bottom of incinerator, the high-temperature flue gas entered in incinerator is made to be evenly distributed like this, mixing air pipeline 4 is attached thereto from incinerator top.High-temperature flue gas produces the high-temperature flue gas produced in equipment 1, substitutes the high temperature dump pit air originally heating up out from steam-air heat exchanger, is divided into primary air, auxiliary air sends into burner hearth respectively.Primary air directly enters incinerator by pipeline, garbage drying; Original dump pit is designed to tiny structure, sprays into incinerator, cause disturbance to flue gas in dump pit after the air extracted mixes with auxiliary air above burner hearth, supplements oxygen amount simultaneously.Described primary air pipeline 3 is diminishing near the caliber at incinerator place, and time such flue gas enters incinerator, flow velocity is very fast, is more conducive to combustion refuse.
As Fig. 3, replace high-temperature flue gas produce equipment 1 by gas turbine 5, after air and natural gas enter gas turbine combustion acting, the high-temperature flue gas of discharge is divided into first and second air to enter participation burning in incinerator respectively.Primary air temperature is higher, first sends in stove and participates in burning, after the air of word dump pit is taken out in auxiliary air mixing, sprays in stove, cause disturbance to air from the top of incinerator.The superheated steam produced, enters in steam turbine and generates electricity.
Hot industry flue gas or combustion turbine exhaustion can be used for waste incineration by preheated air system of the present utility model, reclaim the waste heat of high-temperature flue gas; Increase the combustibility of rubbish, making it when low heat value or underload, can burn without the need to using natural gas combustion-supporting; Transform original incinerator, eliminated air preheater, redesigned heated surface at the end of boiler, under equal waste incineration amount, add the producing steam amount of waste incineration waste heat, improve the heat-economy of power plant; Eliminate steam-air heat exchanger, reduce process steams consumption, improve generated energy; Adopt gas turbine-waste incineration cogeneration, effectively can utilize the high-temperature exhaust air of gas turbine, save fuel, improve the thermal efficiency of power plant.
