Introduction to Process Equipment and Project Investment Estimation

1、 Overview

The complete set of continuous anaerobic pyrolysis technology owned by Sichuan Jianquan Environmental Group Co., Ltd. is a patent chain consisting of nearly 30 national invention patents and utility model patents. Among them, the "continuous oxygen free pyrolysis tubular furnace" is the first in China and the world. It is a historic innovation of Pyrolysis process equipment, which reliably solves the long-standing technical bottleneck of the pyrolysis process, and realizes the continuous industrial clean production of Pyrolysis process. In addition to being used for the ultimate treatment of waste plastics and rubber to generate fuel, gas, and high calorific value carbon without any harmful emissions, the equipment can also be slightly improved according to the same principle and different requirements, and can be used for the drying of wet materials; It can also be used for industrial continuous treatment to remove oil from oily sludge (residual oil rate after treatment is less than 3 ‰); And it can effectively treat some hazardous waste (such as tar residue) and medical organic waste in a safe, environmentally friendly, and low-cost manner, as well as solid waste such as household waste and kitchen waste; It can also be used to extract bio oil and further pyrolysis the residue after extracting bio oil on the same equipment to generate fuel, gas, and high calorific value carbon, achieving the resource utilization and efficient utilization of these residues. The process and equipment for extracting bio oil and making Biochar from its residue are briefly introduced and the project investment is estimated as follows.

1、 Main advantages of process and equipment

1. Continuous and uninterrupted production, achieving remote control of production automation without the need for direct human operation.

2. Except for the organized emission of a small amount of combustion waste gas from the supporting hot air stove (which is the only exhaust outlet of the entire equipment), there is no discharge of wastewater, waste gas, or solid waste. Recycling of hot gas outside the furnace; The gas inside the furnace condenses into liquid (water and oil) and non condensable gas (gas). Realizing a truly environmentally friendly environment.

3. Single unit (set) has high production capacity, and the required production capacity can also be met by adding additional units (sets) to meet the needs of a single factory.

4. Low energy consumption, low cost, and good efficiency.

5. The utilization rate after treatment reaches over 95%, and the yield after treatment (extract or renewable resources) is high. The treatment process has basically no material loss except for water, and there is no carbon emissions. If the extraction rate of camphor oil reaches 95%, the extract is expected to exceed 2.8% (traditional distillation method extract is only 1.6%); It can also produce 1 ton of high-grade charcoal from the residue after extracting about 3-4 tons of raw materials, solving the problem of disposing of existing distillation residue.

6. The equipment is made of special materials, which are wear-resistant, high-temperature resistant, and corrosion-resistant, with a long service life and minimal equipment maintenance.

7. There is no high temperature or high pressure in the process, and the operating temperature is in the medium temperature range (≤ 500 ℃) and micro pressure (≤ 0.03mpa). Except for the inlet and outlet that come into contact with air, the rest are fully enclosed under nitrogen protection, ensuring safe and reliable operation.

8. Large output, high yield, low cost, good efficiency, and short equipment recovery period. The investment payback period for camphor extract and charcoal production shall not exceed 1 year.
