Abstract
The invention discloses a winter garbage unfreezing system and method in a household garbage incineration power plant. The system comprises a garbage storage pit, a garbage crane, a garbage receiving hopper and a percolate pond. A percolate pump is installed in the percolate pond. The percolate pump is connected to a percolate spraying pipeline arranged above the garbage storage pit through a liquid outlet pipeline. A plurality of hot water coiled pipes are arranged at the bottom of the percolate pond. The hot water coiled pipes are externally connected with a hot water inlet pipe and a water outlet pipe. A temperature detection instrument and a valve are installed on the water inlet pipe. A temperature detection instrument is installed on the liquid outlet pipeline connected with the percolate and the percolate spraying pipeline. Due to the fact that the hot water pipeline additionally arranged at the bottom of the percolate pond is used for heating the percolate, the percolate heated inside the pond is conveyed to the spraying pipeline at the upper portion of the garbage storage pit through the percolate pump, the large amount of heated percolate is sprayed to garbage inside the garbage storage pit to be unfrozen and heated, and garbage fermentation and dehydration are promoted.
Description
Technical field
The invention belongs to incineration treatment of garbage technical field is and in particular to a kind of MSW Incineration Plant low temperature environment
The lower method promoting rubbish fermentation and dehydration.
Background technology
With the high speed development of economy and urban construction, quantity of refuse increases year by year, and MSW Incineration Plant increases year by year
Many.MSW Incineration Plant is designed with garbage storing hole to carry out storing to rubbish, ferments, to improve refuse thermal value.Naturally send out
The ferment time with region, temperature difference at 3 days to more than 10 days, mainly cold districts rubbish is difficult to it after freezing
Thaw and heat up.Reasonability according to MSW Incineration Plant design specification and its design itself is it is desirable to house refuse storage is cheated
Reserves should be 5-7 days that is to say, that house refuse storage, the time of fermentation were no more than 5-7 days, otherwise will affect full factory
The reasonability taken up an area, invest and run.Therefore existing manufacturer is to ensure that winter stable operation can be to incinerator using spray
, as auxiliary fuel, production cost increase is very big for oil.The house refuse moisture content of China substantially all between 40-60%, winter
Substantial amounts of ice can be produced after freezing, or even whole rubbish can be frozen into ice cube.The conventional direct blowing hot-air to rubbish and spray into steaming
Vapour brings heat into seldom, and can not go deep into inside rubbish, can not play the effect of defrosting at all.
Content of the invention
Present invention seek to address that rubbish is difficult the problem with dehydration of fermenting under MSW Incineration Plant low temperature environment, carry
Supply a kind of MSW Incineration Plant winter rubbish defrosting system and method it is therefore an objective to promote rubbish preferably to ferment, carried
The calorific value of high rubbish is it is ensured that MSW Incineration Plant normal table runs.
In order to achieve the above object, the present invention employs the following technical solutions realization：
A kind of MSW Incineration Plant winter rubbish defrosting system, including garbage storing hole, garbage crane, rubbish material feeding
Bucket, diafiltration liquid pool；Diafiltration liquid pump is installed in diafiltration liquid pool, diafiltration liquid pump passes through drain pipe road connect setting on garbage storing hole
The percolate spray piping of side；The bottom of described diafiltration liquid pool is provided with many hot-water coil pipes, the external heat of described hot-water coil pipe
Water inlet pipe and outlet pipe, are provided with temperature instrument and valve on hot water inlet pipe；Spray with percolate in described percolate
On the drain pipe road that pipeline connects, temperature instrument is also installed.
Described percolate spray piping is arranged on the height of rubbish hopper top surface bottom 1.9m-2.1m, and percolate sprays
Pipeline enclosure arranges spray apertures every 0.5m-1m.
Described diafiltration liquid pool adopts concrete masonry units structure, and at the bottom of pond adopts anti-corrosion, impervious material.
Described hot-water coil pipe is embedded in the underground in percolate at the bottom of pond portion.
A kind of defreezing method of employing MSW Incineration Plant winter rubbish defrosting system, specific as follows：
1) hot water passing through 50-95 DEG C of Valve controlling enters the hot-water coil pipe in percolate at the bottom of pond portion from hot water inlet pipe, makes heat
Water circulates in hot-water coil pipe, will be percolated liquid pool and internal percolate heating by hot-water coil pipe；
2) pass through temperature instrument, the confluent to hot-water coil pipe for the Valve controlling hot water inlet pipe, thus by percolate plus
Temperature control after heat is at 35-45 DEG C；
3) by being percolated liquid pump, the percolate after heating is delivered to the percolate spray piping that garbage storing cheats top, will add
It is thawed, heat on the rubbish that a large amount of percolates after heat spray in garbage storing hole, promotion rubbish fermentation and dehydration.
Compared with prior art, the invention has the beneficial effects as follows：
This method is that percolate heats by increasing hot water pipeline to percolate at the bottom of pond portion, by being percolated liquid pump by pool heating process
Percolate afterwards is transported to garbage storing hole upper spray pipe road, and a large amount of percolates after heating are sprayed the rubbish in garbage storing hole
On rubbish, it thawed, heat, promote rubbish fermentation and dehydration.The present invention is done using the hot water of waste-to-energy plant output itself
For thermal source, by the use of diafiltration liquid pool itself as heating target, need not set up again at diafiltration liquid pool or garbage storing hole other adding
Hot equipment, operating cost is low；The percolate of high temperature directly sprays in house refuse, can quickly rubbish be thawed,
Defrosting efficiency high.
