Description

Organic solid waste treatment device

Technical Field

The utility model relates to a waste treatment technical field, concretely relates to organic solid waste processing apparatus.

Background

The organic solid waste refers to solid and semi-solid organic waste products generated in production, consumption, life and other activities of human beings, and comprises household garbage, kitchen garbage, industrial waste, medical waste and the like. Currently, the common treatment methods for organic solid wastes are landfill, composting, incineration, and pyrolysis. The pyrolysis technology not only can realize harmless treatment, reduction and recycling of the garbage, but also can effectively overcome the problem of dioxin pollution generated by garbage incineration, so that the pyrolysis technology becomes a garbage treatment technology with a larger development prospect.

At present, the commonly adopted pyrolysis mode is that organic solid waste is directly combusted in a first combustion chamber, oxygen-deficient hot air flow which consumes oxygen in combustion is utilized to pyrolyze subsequent organic solid waste, the generated carbon is taken as fuel to be continuously combusted to generate oxygen-deficient hot air flow, and smoke (containing combustible gas and gaseous oil substances) enters a second combustion chamber to be combusted and purified at high temperature. Sulfur nitrogen oxides, dioxin, heavy metals and other harmful substances are easily wrapped in smoke dust generated by directly burning organic solid wastes, so that a plurality of separation and adsorption measures are required to be added in an exhaust tail section. This way the pyrolysis products are all burned clean, which will produce a large amount of carbon emissions.

There are also other methods and apparatuses for treating organic solid waste resources with superheated steam (see the application of chinese utility model with application publication No. CN106381164A for details), but the purpose of the treatment is the recycling of oil. Because the oil-containing steam of the method is a mixture of oil and other liquids after being condensed, and the other liquids contain various harmful substances carried in the original organic solid waste resources, the harmless emission can be realized by various methods. Therefore, the cost of refining the available oil and fat is higher than the value of the oil and fat per se and is irrevocable. In addition, the device needs to stir the organic solid waste resources in the treatment process, so that the ash content in the flue gas is high, the dust removal treatment is needed, and the treatment cost is high.

In addition, the existing pyrolysis technology device needs to break the organic solid waste before treatment, so that not only is the treatment cost higher, but also the unpacking and the breaking have great infectious risks when treating infectious sealed medical waste.

The air inlet of the exhaust pipe 50 is communicated with the air outlet of the pyrolysis chamber 21, and the air outlet of the exhaust pipe 50 is communicated with the primary combustion chamber 12. The exhaust duct 50 is used to introduce a mixed gas formed by the pyrolysis gas and the superheated steam generated in the pyrolysis chamber 21 into the primary combustion chamber 12 for combustion.

The hot air in the secondary combustion chamber 13 and/or the heating chamber 11 is discharged to the atmosphere through the discharge device 30, and the air inlet of the discharge device 30 is communicated with the hot air discharge port of the heating chamber 11 and/or the secondary combustion chamber 13.

The auxiliary fuel combustor 70 is used to combust the auxiliary fuel in the primary combustion chamber 12, the auxiliary fuel being separately supplied from the outside,

in one embodiment, the above-mentioned discharge device 30 includes a first discharge pipe 31, a first valve 32, a second discharge pipe 33, a second valve 34, and a total hot gas discharge pipe 35. The inlet port of the first exhaust duct 31 communicates with the hot gas discharge port of the heating chamber 11, and the inlet port of the second exhaust duct 33 communicates with the hot gas discharge port of the secondary combustion chamber 13. A first valve 32 is installed in the first discharge pipe 31 for controlling the flow rate of the gas in the first discharge pipe 31. A second valve 34 is installed in the second discharge pipe 33 for controlling the flow rate of the gas in the second discharge pipe 33. The first valve 32 and the second valve 34 may be gate valves, butterfly valves, or other valves, and may be controlled automatically by pneumatic, hydraulic, or electric means. The air inlet of the total hot air exhaust pipe 35 is communicated with both the air outlet of the first exhaust pipe 31 and the air outlet of the second exhaust pipe 33, so that the hot air is finally collected and exhausted into the atmosphere.

In the present embodiment, the temperature of the heating chamber 11 is controlled by controlling the flow rate of the hot air in the first and

second exhaust pipes

31 and 33. Specifically, in the initial heating stage, the second valve 34 is in a closed state, so that the hot air flow generated by the second valve is totally introduced into the heating chamber 11, and the hot air discharge is totally discharged through the first discharge pipe 31; when the temperature of the heating chamber 11 reaches the pyrolysis requirement, the second valve 34 is properly opened to allow a part of the hot airflow of the secondary combustion chamber 13 to be diverted so as to keep the temperature of the heating chamber 11 constant.

In one embodiment, the organic solid waste treatment apparatus further includes a first superheater 81 and a second superheater 82 provided on the superheated steam supply pipe 40.

The first superheater 81 is installed in the total hot gas discharge duct 35, and serves to absorb heat of the hot gas in the total hot gas discharge duct 35 and to heat the superheated steam flowing therethrough for the first time. The first superheater 81 uses the residual heat of the flue gas to heat the superheated steam for the first time.

The second superheater 82 is installed at the hot gas discharge port of the heating chamber 11 or the air inlet of the first discharge duct 31, and preferably the second superheater 82 is installed at the hot gas discharge port of the heating chamber 11. The second superheater 82 is for absorbing heat of the hot gas at the hot gas discharge port of the heating chamber 11 and secondarily heating the superheated steam flowing from the inside thereof. The second superheater 82 generates high-temperature superheated steam by making full use of residual heat in the heating chamber 11.

The two-stage heating of the superheated steam by the first superheater 81 and the second superheater 82 allows the superheated steam source to meet the requirements of the processing plant operation as long as it provides low-temperature superheated steam (greater than 100 ℃). In order to prevent salt explosion when saturated steam directly enters the first superheater 81, the introduced steam should be slightly superheated steam. Therefore, when the superheated steam source is connected, the matched steam generator should be provided with a superheating device.

Water for use in a steam generator to generate steam includes, but is not limited to: pure water, surface water, ground water, reclaimed water, and various sources of water to which additives have been added to prevent scaling, salt explosion, rusting, etc. of boilers.

Since the organic solid waste is doped with a small amount of phosphate during the carbonization process, the heavy metal locking capacity of the organic solid waste after carbonization can be improved, water containing a phosphate softener is preferably used for preparing superheated steam.

In this embodiment, since the superheated steam has a large molecular density and a large heat capacity in a low temperature (greater than 100 ℃), a heat exchanger having a large area is required to rapidly raise the temperature of the superheated steam. As the temperature of the superheated steam increases, the heat capacity of the superheated steam will be greatly reduced (non-linearly reduced), so that a smaller heat exchanger area may be used when the temperature of the superheated steam exceeds 600 ℃. Therefore, it is preferable that the heat exchange area of the first superheater 81 is larger than the heat exchange area of the second superheater 82.

In one embodiment, as shown in fig. 2, the organic solid waste treatment apparatus further includes a bypass pipe 42, a third valve 43, and a fourth valve 83. The bypass pipe 42 is provided on the hot steam supply pipe in parallel with the second superheater 82, the third valve 43 is installed on the bypass pipe 42, and the fourth valve 83 is installed at the air inlet of the second superheater 82. The third valve 43 is used to realize the shut-off and the flow of the superheated steam in the bypass line 42, and the fourth valve 83 is used to realize the shut-off and the flow of the superheated steam in the second superheater 82.

Through the arrangement, three use forms of series connection, parallel connection and single use can be realized between the first superheater 81 and the second superheater 82 according to requirements. For example, when the temperature of the superheated steam ultimately used to heat the organic solid waste is not required to be so high, the fourth valve 83 may be closed and the third valve 43 may be opened so that the superheated steam flows through the bypass line 42 and ultimately into the pyrolysis chamber 21.

In one embodiment, the organic solid waste treatment apparatus further includes a front harmful gas input pipe 90 passing through the heating chamber 11, a gas inlet of the front harmful gas input pipe 90 is connected to a harmful gas source, and a gas outlet thereof is communicated with the gas exhaust pipe 50. The pre-harmful gas is a mixture containing harmful volatile matters and water vapor with bad smell generated in the processes of stacking, drying, sorting and crushing the organic solid waste. The front harmful gas is firstly introduced into the heating device through the front harmful gas input pipe 90, so that the mixed gas of the organic volatile matters in the pipeline is pyrolyzed to generate combustible gas, and then the combustible gas and the pyrolysis gas generated in the pyrolysis chamber 21 are combined and introduced into the primary combustion chamber 12 for combustion through the pyrolysis gas burner 60, and are completely combusted in the high-temperature combustion of the secondary combustion chamber 13 up to 1100 ℃, and finally discharged into the atmosphere.

In one embodiment, the auxiliary fuel is liquefied petroleum gas or heavy oil. The two fuels are preferred as auxiliary fuels for the following reasons:

the combustion heat value of the two fuels is 3 times of that of natural gas under the common combustion condition, the combustion heat value is high, and the two fuels are treated by the treatment device provided by the utility model, and are subjected to displacement, gasification and modification reaction after being expanded in the secondary combustion chamber 13, so that the heat value of the two fuels after being fully combusted can reach more than 4 times of that of the natural gas;

secondly, due to the existence of the superheated steam, the liquefied petroleum gas or the heavy oil can be completely combusted, namely the heat value in the liquefied petroleum gas or the heavy oil is completely squeezed, so that no waste is caused. And the superheated steam is fully utilized and supplements each other, so that the using effect is better.

The utility model provides an organic solid waste processing apparatus's theory of operation as follows:

the auxiliary fuel combustor 70 is ignited, the second valve 34 is closed, the first valve 32 is opened, the auxiliary fuel is combusted in the first-stage combustion chamber 12, the combustion gas is gasified and combusted in the second-stage combustion chamber 13 through the barrier 14, hot air of the second-stage combustion chamber 13 rises to the heating chamber 11, when the temperature of the heating chamber 11 rises to 400 ℃, low-temperature superheated steam (more than 100 ℃) is introduced into an interface of the first superheater 81, the low-temperature superheated steam is directly heated in the pyrolysis chamber 21 through the steam nozzle 41 after being heated in two stages by the first superheater 81 and the second superheater 82, mixed gas of pyrolysis gas and superheated steam generated by anaerobic pyrolysis of organic solid wastes in the pyrolysis chamber 21 is injected into the first-stage combustion chamber 12 through the exhaust pipe 50, and is combusted in the pyrolysis chamber 21 through the pyrolysis gas combustor 60. The pyrolysis gas in the initial stage of pyrolysis is basically small molecule combustible gas, and can be burnt completely in the secondary combustion chamber 13. When the temperature of the second superheater 82 is greater than 400 ℃, the supply of the auxiliary fuel can be reduced until the supply of the auxiliary fuel is stopped, the self-sufficiency of the heat energy is realized by completely depending on the combustion of the pyrolysis gas, and the first valve 32 and the second valve 34 are adjusted to increase the flow rate of the second discharge pipe 33 and decrease the flow rate of the first discharge pipe 31 so as to maintain the superheated steam at a temperature between 400 ℃ and 900 ℃. The gas from the pyrolysis contains a large amount of oil vapor which is not easily completely combusted. In the secondary combustion chamber 13, the superheated steam with the temperature of more than 600 ℃ participates in combustion, carries out replacement, gasification and modification reactions, and finally can realize full combustion and harmless emission. In addition, if the harmful gas is treated, the harmful gas input pipe 90 is connected when the superheated steam reaches 400 ℃, and the harmful gas and the pyrolysis gas are mixed and combusted in the pyrolysis gas burner 60 through the exhaust pipe 50.
