Abstract
The invention provides a system and a method for winter refuse wet-steaming and fermentation to solve the problem that refuse brought in winter is low in temperature, low in humidness and poor in fermentation effect. The refuse wet-steaming and fermentation system comprises a refuse store (1), a feed hopper (2), a main steam pipe (4), a steam outlet pipe (5) and a steam inlet pipe (6), wherein the main steam pipe (4), the steam outlet pipe (5) and the inlet pipe (6) are connected with a stream source. A plurality of steam inlets (3) are reserved on the upper middle wall of the refuse store (1). The steam outlet pipe (5) is disposed on the main steam pipe (4). On end of the steam inlet pipe (6) is connected with the steam outlet pipe (5), and the other end of the steam inlet pipe (6) is connected to the steam inlets (3). A valve (7) is installed on the steam inlet pipe (6). Refuse in the refuse store (1) can be pushed to the steam inlets (3), steam can be fed into the refuse store (1) for wet steaming after the valve is opened (7), and residual steam can be used for wet steaming continuously after the valve (7) is closed. The pressure steam is fed into a refuse dump to humidify and heat the refuse, so that the fermentation conditions for the refuse are improved.
Description
Technical field
The invention belongs to environmental technology field, be specifically related to the rubbish fermentation system and method for domestic garbage burning electricity generation factory, the fermentation condition that is particularly useful for improving the house refuse in winter generates electricity with abundant flameholding.
Background technology
At present, the rubbish storehouse of storing rubbish is all had in domestic garbage burning electricity generation factory, at first will be through fermentation in a few days before the waste incineration.The purpose of fermentation is in order to improve the calorific value into stove rubbish, and it is good more ferment, and calorific value is high more, can make boiler combustion stable and economy is good more more.In certain fermentation time, if make the effective rubbish temperature that depends primarily on of rubbish fermentation want height and rubbish to contain certain moisture.Summer go into factory's rubbish temperature height and refuse moisture big, ferment effect is best, season in spring and autumn still can, the power plant that fires rubbish entirely generally can flameholding at summer spring and autumn boiler.To go into factory's rubbish temperature low and moisture rubbish is few winter, the rubbish fermentation condition is very bad.In order to guarantee ferment effect as far as possible; Usually can only prolong the fermentation time of rubbish; But the fermentation time of rubbish receives the restriction that the rubbish Kuku holds, and causes boiler in the winter time under the situation of clean burn rubbish, has only frequent throwing oil combustion-supporting; Could guarantee that furnace temperature more than 850 ℃ safety line, makes production cost increase considerably.
Summary of the invention
To go into factory's rubbish temperature winter low and refuse moisture is few, ferment effect is poor, the unsettled objective condition of boiler combustion in order to overcome, and the present invention provides the wet evaporation of a kind of rubbish in winter ferment system and method.Wet steaming fermentation method is that steam is sent in the rubbish heap inside of showing in the rubbish storehouse, outwards gives rubbish humidification and temperature raising from the lining, improves two the necessary fermentation conditions of rubbish in the rubbish storehouse, and rubbish also can be fermented in the winter time preferably.
For system provided by the present invention, the technical scheme that is adopted is: the wet evaporation of a kind of domestic garbage burning electricity generation factory's rubbish in winter ferment system, and comprising: rubbish storehouse, feeding hopper, said feeding hopper are arranged at a side in rubbish storehouse; Also comprise the female pipe of the steam that is connected with vapour source, steam outlet pipe and steam inlet pipe; Body of wall place, middle and upper part in said rubbish storehouse is provided with several air intakes; Steam outlet pipe is arranged on the female pipe of the described steam that is connected with vapour source; Said steam inlet pipe one end is connected with steam outlet pipe, and the other end is connected to air intake, on the said steam inlet pipe valve is installed.
As a kind of preferred, said air intake is arranged at the rubbish storehouse and is provided with on the body of wall of feeding hopper side, and is evenly distributed.
As a kind of preferred, said air intake is 2 to 8.
As a kind of preferred, the diameter of said steam inlet pipe is 159 millimeters; The diameter of said steam outlet pipe is 76 millimeters.
As a kind of preferred, said steam inlet pipe and steam outlet pipe all adopt stainless steel.
For method provided by the present invention; The technical scheme that is adopted is: a kind of wet evaporation of domestic garbage burning electricity generation factory rubbish in winter fermenting process that uses the wet evaporation of above-mentioned rubbish ferment system; May further comprise the steps: a, drop into rubbish the rubbish storehouse from garbage inlet, and pile to the air intake place; B opens the valve on the steam inlet pipe, in the rubbish storehouse, sends into steam through air intake, carries out wet steaming of a step; C, valve-off stops admission, utilizes the steam that remains in the rubbish heap, proceeds wet steaming of two steps.
As a kind of preferred, the described wet time of steaming in a step is 8 hours; The control steam pressure is 0.3Mpa when steam is sent in the rubbish storehouse; And control rubbish storehouse temperature is 200 ℃.
In the rubbish storehouse of garbage incinerating power plant, because the rubbish heap of middle and upper part gets late and burns early, fermentation time is the shortest; And the rubbish pressure of middle and upper part is little, temperature is low; Burn so the rubbish of middle and upper part is the most difficult, send into steam in this way the rubbish heap inside in the rubbish storehouse, come from the lining outwards to give rubbish humidification and temperature raising; Improve two the necessary fermentation conditions of rubbish, accomplish to make rubbish also can ferment preferably in the winter time in the rubbish storehouse.
Since refuse-burning plant usually with garbage crane with sanitary fill in the feeding hopper side, the rubbish of feeding hopper side usually the ratio of heap higher and pile late burning morning, fermentation time is short; The little temperature of rubbish pressure is low nonflammable; Therefore, air intake is arranged at the rubbish storehouse is provided with on the body of wall of feeding hopper side, in this position admission; Can heat up for better the rubbish humidification, improve fermentation condition.
In the present invention, described vapour source can be the low-pressure steam that comes from steam generator system or steam turbine system.
The wet evaporation of rubbish provided by the invention ferment system and method through outwards give rubbish humidification and temperature raising from the lining, has improved the fermentation condition of domestic garbage burning electricity generation factory rubbish in winter; Make winter rubbish also efficiency ferment well; Improve the calorific value of going into stove rubbish, boiler is fired under the situation of house refuse in the winter time entirely, also can reach the safety line above (remaining on about 1000 ℃) that ignition temperature is stabilized in 850 ℃; Reduce boiler and throw oily combustion-supporting number of times (it is combustion-supporting not throw oil basically), reduced production cost.
