Embodiment 1

[0021] An alkaline biomass granule used to incinerate organic waste liquid. The organic waste liquid is sprayed on the biomass granule and then incinerated. The components include the following components:

[0022]

[0023] 0.2 parts of sodium hydroxide, the sodium hydroxide is mixed with raw materials in the form of aqueous solution sprayed on the biomass powder, and then extruded and granulated.

[0024] Calcium carbonate is selected as the desulfurizer, urea is selected as the out-of-stock reducing agent, and Akzo DU958 is selected as the grade of expansion microspheres.

[0025] Biomass powder is selected from domestic garbage biomass waste such as kitchen waste powder, industrial biomass waste such as sawdust, or agricultural biomass waste such as discarded mushroom sticks.

[0026] During the granulation process of biomass particles, the general temperature is 80-100°C, and the selection of expanded microspheres with an initial foaming temperature above 120°C can effe...

Abstract

The invention discloses alkaline biomass particles for incinerating organic waste liquid and special equipment. Particles comprise biomass powder, a desulfurizing agent, a denitration reducing agent,expansion microspheres and sodium hydroxide; the special equipment comprises an incineration chamber, a negative pressure fan, a first movable fire grate, a second movable fire grate, a primary air inlet and a feeding system, wherein the negative pressure fan is connected with the bottom of the incineration chamber, the primary air inlet is formed above the first movable fire grate, a C-shaped high-temperature heat pipe is further arranged, and an organic waste liquid storage tank is further arranged on a feeding auger. Compared with the prior art, the alkaline biomass particles have the following advantages: the biomass particles contain the desulfurizing agent, the denitration agent and the expansion microspheres, so that the desulfurizing agent and the denitration agent can be sprayed in a combustion atmosphere; particles are in co-current contact with air, so that the phenomenon of incomplete combustion is reduced; the C-shaped high-temperature heat pipe is used for conducting heatto an inlet, energy is effectively utilized for igniting particles, and the effective combustion time is prolonged; the air inlet system is reasonable in design, the side wall of the incineration chamber is effectively protected and potential safety hazards are avoided.

Description

technical field [0001] The invention relates to the technical field of combustion and the technical field of organic waste disposal, in particular to alkaline biomass particles and special equipment for incineration and disposal of organic waste liquid. Background technique [0002] The harmless disposal of organic waste is an important issue facing society today, especially the disposal of hazardous liquid waste generated in some special occasions. For example, the organic waste liquid produced by scientific research institutes, universities and special industries has the characteristics of small output, many and complex components, and it is difficult to carry out effective harmless disposal. Incineration is a common disposal method. Atomization of liquid fuel is often used for liquid fuel. In this method, the residence time of fuel is short, and incomplete combustion of fuel with complex components is easy to occur, and organic waste liquid contains sulfur and nitrogen. ...
