Embodiment 1

[0033] Such as figure 1 As shown, this embodiment provides a biomass waste treatment system, which includes a process control unit, and a demulsification tank 1 , a cyclone separator 2 and a hydrothermal reaction unit 3 connected in sequence. The demulsification tank 1, the cyclone separator 2 and the hydrothermal reaction unit 3 are respectively connected to the process control unit so that the process control unit can control its working process.

[0034] In this embodiment, the process control unit is a programmable logic controller (PLC), which is an existing technology understandable by those skilled in the art, and will not be described in detail herein.

[0035] The demulsification tank 1 includes a tank body 11, an agitator is arranged inside the tank body 11, and the agitator rotates under the drive of a motor 13, and the motor 13 is arranged on the top outside of the tank body 11. The stirrer 13 includes a stirring shaft 121, one end of the stirring shaft 121 is con...

Embodiment 2

[0045] This embodiment provides a treatment method for biomass waste, which is based on the biomass waste treatment system in Example 1, which includes the following steps:

[0046] Step 1: Under the automatic control of the process control unit, transport the material to the demulsification tank, use the flash steam generated by the flash treatment to preheat, raise the temperature to 60-100°C, and demulsify under the action of the demulsifier , and at the same time break some living cells and flocs, promote the dissolution of bound water, reduce the viscosity of the material and then enter the cyclone separator.

[0047] Step 2: The liquid phase material enters along the tangential direction of the inner wall of the cyclone separator. Due to its special structure, the liquid phase material enters the cyclone separator, and the material uses the involute principle to form first downwards and then upwards in the cyclone separator. The two-stage cyclone, under the action of cen...

Embodiment 3

[0052] This embodiment provides a demulsifier, which can be applied to the understanding process in Example 2, especially for the understanding of biomass waste, for promoting solid-liquid separation in biomass waste and reducing its viscosity.

[0053] The demulsifier provided in this embodiment consists of 90-120 parts by mass of propylene oxide, 30-40 parts of triethanolamine, 25-40 parts of sodium dodecylsulfonate, and 20-28 parts of C2-C6 carboxylic acid , 18-25 parts of ethylene glycol monobutyl ether, and 12-15 parts of ammonium chloride.

[0054] Take 100 parts of propylene oxide, 40 parts of triethanolamine, 30 parts of sodium dodecylsulfonate, 25 parts of n-hexanoic acid, 20 parts of ethylene glycol monobutyl ether, and 12 parts of ammonium chloride, and mix them uniformly to obtain a demulsifier.

[0055] Take a biomass waste, viscous sludge, 19 ℃, divide it into four parts on average, put them into transparent glass cups; The condition of 6g / 100g sludge is added w...

Abstract

The invention discloses a biomass waste treatment system and method, and relates to the technical field of environmental protection. The biomass waste treatment system comprises a flow control unit, ademulsification tank, a cyclone separator and a hydrothermal reaction unit, and the demulsification tank, the cyclone separator and the hydrothermal reaction unit are sequentially connected. The flowcontrol unit is connected to the demulsification tank, the cyclone separator and the hydrothermal reaction unit separately so as to control the working processes of the demulsification tank, the cyclone separator and the hydrothermal reaction unit. The inner diameter of the cyclone separator is sequentially reduced from top to bottom, and the cyclone separator is also provided with a material inlet, a liquid phase outlet and a solid phase outlet. The material inlet is formed in the upper side wall and is tangent to the side wall, the solid-phase outlet is formed in the bottom of the cyclone separator, and the liquid phase outlet is formed in the top of the cyclone separator. The method is based on the system. The biomass waste treatment system and method are used for multi-stage treatmentof biomass waste, and the dehydration property and anaerobic digestion performance of the biomass waste are improved, so that the harmless and recycling effects of the biomass waste are improved.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to the technical field of viscous fluid or semi-solid waste treatment, and in particular to a treatment system and method for biomass waste. Background technique [0002] Biomass waste is the waste generated by human production and consumption in the process of utilizing biomass, and the main pollutants are living cells and organic matter. According to its sources: (1) Urban biomass waste mainly includes household kitchen waste, kitchen waste, urban manure and urban sludge; (2) Agricultural waste mainly consists of corn straw, wheat straw and rice straw; ( 3) Livestock manure. Biomass waste has potential threats to regional water environment, atmosphere and soil environment. The large amount of malodorous gas generated under the accumulation conditions of easily degradable biomass waste is also one of the important factors affecting the surrounding air quality; th...
