17885414_1 (GHMatters) P116726.AU
Description
[01] The present disclosure relates to the field of fertilizer technology, and more specifically, relates to a method for preparing a biomass-based composite material for
repairing saline-alkali soil.
[02] A large amount of livestock and poultry manure produced by the breeding industry not only causes water pollution, but also causes air pollution in the surrounding
environment. Although the livestock and poultry manure is equivalent to undergoing a
certain degree of composting during collection and storage, there are still germs, insect
eggs or weed seeds, and thus it is not suitable for direct application in farmland. If the
large amount of manure is composted, it will not only take up a lot of land resources,
but also exacerbate the air pollution in the surrounding environment. On the other hand,
in agricultural production, the straw is usually returned to the field directly after
crushing or returned to the field after incineration. The fertility effect of returning
directly to the field after crushing is very slow. The direct emission of flue gas after the
straw incineration may cause air pollution, and the ash after the incineration is alkaline,
having no sustainability.
[03] In view of this, the technical problem to be solved by the present disclosure is to
provide a method for preparing a biomass-based composite material for repairing
saline-alkali soil, which makes the livestock and poultry manure, and the agricultural
straw turn into treasures, thereby continuously providing a slow release fertilizer for
crops.
[04] In order to solve the above technical problem, the present disclosure provides the
following technical solutions:
[05] A method for preparing a biomass-based composite material for repairing
saline-alkali soil, comprising:
[06] Step A: crushing a straw, and transporting the crushed straw to a cracking furnace
17885414_1 (GHMatters) P116726.AU for thermal cracking, to obtain a high-temperature cracking gas and a straw biomass char;
[07] Step B: transporting the straw biomass char to a mixing tank, adding a livestock and poultry manure thereto, and mixing the straw biomass char and the livestock and
poultry manure, to obtain a biomass slow release fertilizer; and
[08] transporting the biomass slow release fertilizer to a sterilization and drying device, while transporting the high-temperature cracking gas to the sterilization and drying
device to dry the biomass slow release fertilizer, to obtain a low-temperature cracking
gas, a dried biomass slow release fertilizer and a biomass oil; and
[09] Step C: transporting the low-temperature cracking gas to the mixing tank for pneumatic mixing of the straw biomass char and the livestock and poultry manure
therein and pre-drying of the resulting mixture, and packaging the dried biomass slow
release fertilizer, and collecting the biomass oil.
[10] In above method of preparing a biomass-based composite material for repairing saline-alkali soil, in some embodiments, the cracking furnace is fixedly connected with
a first feed pipe at the top, a first discharge port at the bottom, and a first air outlet pipe,
a second air outlet pipe and a third air outlet pipe at one side.
[11] In above method of preparing a biomass-based composite material for repairing
saline-alkali soil, in some embodiments, the mixing tank is fixedly connected with a
second discharge port at the bottom, and a second feed pipe and a third feed pipe at the
top, and also a first air inlet pipe at the upper surface; the first air inlet pipe is connected
to an air outlet port on the top of the sterilization and drying device; afirst steam turbine
is fixedly installed on the top of the mixing tank, and a driving gas inlet of the first
steam turbine is in fluid communication with a second air outlet pipe; an output end of
the first steam turbine is drivingly connected with a stirring shaft, and a free end of the
stirring shaft with stirring blades is located inside the mixing tank.
[12] The technical solution provided by the present disclosure has the following
beneficial effects:
[13] In the present disclosure, the rubber sheet installed on the sterilization and drying
device is lapped on the upper and lower surfaces of a link plate to seal the inlet and 2 17885414_1 (GHMatters) P116726.AU outlet of the link plate, which could effectively reduce the gas leakage inside the sterilization and drying device; moreover, the rubber sheet has a certain elasticity, and thus would not scrape off a large number of materials delivered on the link plate.
[14] The method of the present disclosure could dry the materials three times by using the cracking gas inside the mixing tank, the first drying chamber and the second drying
chamber, and the temperature of the cracking gas during the three drying is increased
sequentially, so that the materials could be dried more thoroughly.

[21] The technical solutions in the embodiments of the present disclosure will be clearly and completely described in detail below with reference to the accompanying
drawings in the examples. It should be understood that the described examples are only
a part of the examples of the present disclosure, not all of the examples. Based on the
examples of the present disclosure, all other examples obtained by those skilled in the
art without creative work should fall within the protection scope of the present
disclosure.
[22] As shown in FIG. 1, the method for preparing a biomass-based composite material
for repairing saline-alkali soil in the example comprises:
[23] Step A: crushing a straw, and transporting the crushed straw to a cracking furnace
100 for thermal cracking, to obtain a high-temperature cracking gas and a straw biomass
char;
[24] Step B: transporting the straw biomass char to a mixing tank 300, adding a livestock and poultry manure thereto, and mixing the straw biomass char and the
livestock and poultry manure, to obtain a biomass slow release fertilizer; and
[25] transporting the biomass slow release fertilizer to a sterilization and drying device
200, while transporting the high-temperature cracking gas to the sterilization and drying
device 200 to dry the biomass slow release fertilizer, to obtain a low-temperature
cracking gas, a dried biomass slow release fertilizer and a biomass oil; and
[26] Step C: transporting the low-temperature cracking gas to the mixing tank 300 for
pneumatic mixing of the straw biomass char and the livestock and poultry manure
therein and pre-drying of the resulting mixture, and packaging the dried biomass slow
release fertilizer, and collecting the biomass oil
[27] As shown in FIG. 1, the cracking furnace 100 is fixedly connected with a first feed
pipe 101 at the top, a first discharge port 102 at the bottom, and a first air outlet pipe
103, a second air outlet pipe 104 and a third air outlet pipe 105 at one side.
[28] Working principle is described as follows: a straw is crushed, and the crushed
straw is transported to a cracking furnace 100 for thermal cracking, to obtain a
high-temperature cracking gas and a straw biomass char; the straw biomass char is 4 17885414_1 (GHMatters) P116726.AU transported to a mixing tank 300, and a livestock and poultry manure is added thereto, and they are mixed, to obtain a biomass slow release fertilizer; the biomass slow release fertilizer is transported to a sterilization and drying device 200, while the high-temperature cracking gas is transported to the sterilization and drying device 200 to dry the biomass slow release fertilizer, to obtain a low-temperature cracking gas, a dried biomass slow release fertilizer and a biomass oil; the low-temperature cracking gas is transported to the mixing tank 300 for the pneumatic mixing of the straw biomass char and the livestock and poultry manure therein and pre-drying of the resulting mixture, and the dried biomass slow release fertilizer is packaged, and the biomass oil is collected.
[29] The straw is crushed, and subjected to a thermal cracking to obtain a straw biomass char and a high-temperature cracking gas, respectively. The straw biomass char are mixed with the livestock and poultry manure, which could not only avoid the shortcomings of direct application of the straw biomass char, but also achieve the purpose of water and fertilizer preservation by utilizing the characteristics of porous and strong adsorptionn of the straw biomass char. The high temperature cracking gas could kill the germs, eggs and weed seeds in the livestock and poultry manure, making the livestock and poultry manure be directly applied without special composting, thereby saving the land resources occupied by compost and avoiding pollution gas emission produced during the composting. The low-temperature cracking gas discharged from the sterilization and drying device 200 is transported to the bottom of the mixing tank 300 through the first air inlet pipe 304, which plays a role of pneumatic stirring on the one hand, and of pre-drying of the materials on the other hand, and also realizes the temperature rise during the mixing process of the livestock and poultry manure and the straw biomass char, making the mixing process equivalent to a low-temperature composting fermentation. The high-temperature cracking gas is in contact with the pre-dried biomass slow release fertilizer in the sterilization and drying device, making the livestock and poultry manure equivalent to undergoing a short high-temperature composting, while making the biomass oil carried in the high-temperature cracking gas attach to the surface of the biomass slow release fertilizer to form an oil film, so as to 5 17885414_1 (GHMatters) P116726.AU achieve a slow and controlled release of fertilizer efficiency.

For those skilled in the art, other variations or changes in different forms could also be made based on the above description. It is not necessary and impossible to list all the embodiments here. The obvious variations or changes derived therefrom should still fall within the protection scope of the claims of the present disclosure.
[31] It is to be understood that, if any prior art publication is referred to herein, such reference does not constitute an admission that the publication forms a part of the common general knowledge in the art, in Australia or any other country.
