Abstract
The utility model discloses a msw incineration boiler wall cooling air improves structure absorbs the hot-blast introduction of waste heat stove air-cooled wall to rubbish hole with msw incineration boiler wall cooling draught fan, sets up pipeline to the inside platform of garbage storehouse from the boiler wall cooling draught fan of boiler to a tuber pipe entry position. The temperature of the garbage bin is raised by utilizing the heat of the furnace wall cooling air, the garbage fermentation is promoted, and the energy is saved. When the outdoor environment temperature is-20 ℃ in winter, the environment temperature of the garbage bin is about 0 ℃, and the garbage bin can be heated to about 30 ℃ through furnace wall cooling air. Through the utility model discloses reform transform back furnace wall cooling air and get into in the garbage storehouse with the inside air heat transfer in garbage storehouse, make once wind absorb the inside temperature in garbage storehouse and improve also the rubbish fermentation.
Description
Technical Field
The utility model relates to a waste incineration technical field.
Background
The wall cooling air of the conventional design is discharged to a primary air inlet pipeline of the garbage incinerator through a wall cooling air induced draft fan after absorbing the heat of the wall through an air feeder. However, the problem of low temperature of the garbage bin exists in northern areas in winter, and when the outdoor environment temperature is-20 ℃ in winter, the environment temperature of the garbage bin is about 0 ℃. And the furnace wall cooling air is not sent to the garbage bin in the prior art, and the heat of the cooling air is used for heating the environmental temperature of the garbage bin. Through the furnace wall cooling air improved structure of the utility model, the furnace wall cooling air can be heated to about 30 ℃.
Disclosure of Invention
In order to solve the low problem of northern area rubbish storehouse temperature in winter, the technical scheme of the utility model be one kind and send the brickwork cooling air to the rubbish storehouse, be used for heating rubbish storehouse ambient temperature with the heat of cooling air. When the outdoor environment temperature is-20 ℃ in winter, the environment temperature of the garbage bin is about 0 ℃, and the garbage bin can be heated to about 30 ℃ through furnace wall cooling air.
In order to achieve the purpose, the utility model provides a waste incineration boiler furnace wall cooling air improves structure utilizes waste incineration furnace wall cooling draught fan to absorb the empty cold wall of waste heat stove and hot-blast to lead to the rubbish hole in, improves the inside temperature in garbage storehouse and the rubbish fermentation heats, improves the rubbish fermentation condition, warp the utility model discloses reform transform back furnace wall cooling air and get in the garbage storehouse with the inside air heat transfer in garbage storehouse, make a wind inhale and get the inside temperature in garbage storehouse and improve also improve the rubbish fermentation.
After a pipeline is additionally arranged from a furnace wall cooling induced draft fan of a boiler to an inlet of a primary air pipe to an inner platform of a garbage bin, a main pipeline branches to a west side pool wall of a garbage pit and descends, the garbage pit is supplied with air temperature after being cooled by an air cooling wall of a waste heat furnace, and a walking route of cooling air can be controlled by additionally arranging two flap gates on the pipeline.
The technical effects are as follows: the temperature of the garbage bin is raised by utilizing the heat of the furnace wall cooling air, the garbage fermentation is promoted, and the energy is saved. When the outdoor environment temperature is-20 ℃ in winter, the environment temperature of the garbage bin is about 0 ℃, and the garbage bin can be heated to about 30 ℃ through furnace wall cooling air. Through the utility model discloses reform transform back furnace wall cooling air and get into in the garbage storehouse with the inside air heat transfer in garbage storehouse, make once wind absorb the inside temperature in garbage storehouse and improve also the rubbish fermentation.
Drawings
Fig. 1 is a schematic structural view of cooling air of a furnace wall of a conventional waste incineration boiler.
Fig. 2 is a schematic view of an improved structure of cooling air for a furnace wall of a waste incineration boiler provided by the embodiment.
Description of reference numerals: 1. cooling the induced draft fan; 2. a pipeline.
Detailed Description
In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.
Examples
Fig. 1 is a schematic structural view of cooling air of a furnace wall of a conventional waste incineration boiler, and fig. 2 is an improvement made on the basis of the cooling air. The improved structure schematic diagram of the cooling air of the furnace wall of the waste incineration boiler provided by the embodiment is characterized in that a waste incineration furnace wall cooling draught fan is used for sucking hot air of the air cooling wall of the waste heat furnace to lead the hot air into a waste pit, the internal temperature of the waste bin and the waste fermentation are improved to heat, the waste fermentation condition is improved, a pipeline 2 is additionally arranged from a furnace wall cooling draught fan 1 of the boiler to a primary air pipe inlet to a platform inside the waste bin, a main pipeline is branched to the west side pool wall of the waste pit and descends, the waste pit is supplied with the air temperature after the air cooling wall of the waste heat furnace is cooled, and two flap doors are additionally arranged on the pipeline to control the walking route of the cooling air. Through the utility model discloses reform transform back furnace wall cooling air and get into in the garbage storehouse with the inside air heat transfer in garbage storehouse, make once wind absorb the inside temperature in garbage storehouse and improve also the rubbish fermentation.
Claims (2)
1. The utility model provides a waste incineration boiler furnace wall cooling air improves structure, characterized by, draws the hot-blast introduction of waste heat stove air-cooled wall to the rubbish hole with waste incineration furnace wall cooling draught fan, sets up pipeline (2) to rubbish storehouse inner platform from furnace wall cooling draught fan (1) to the tuber pipe entry position of boiler.
