The application discloses a biomass pyrolysis system for co-production of tar and fuel gas, which comprises a casing, a crushing mechanism and a crushing cylinder, the crushing mechanism is rotatably installed in the casing, the crushing cylinder is fixedly installed on the bottom of the crushing mechanism, the crushing cylinder is coaxially arranged with the casing, a crushing space is formed between the outer wall of the crushing cylinder and the inner wall of the casing, a feeding port is formed in the top of the casing, and an outer discharging port is formed in the bottom of the casing; a driving assembly is installed on one side of the casing, the output end of the driving assembly is drivingly connected with the crushing mechanism, the driving assembly drives the crushing mechanism to rotate in the casing, and a fixed gear ring is coaxially and fixedly installed in the casing. The biomass raw material can be crushed through the crushing mechanism, the biomass raw material can be finely processed to the maximum extent during crushing, and the pyrolysis speed can be improved during pyrolysis.

This utility model relates to the field of arc extinguishing devices and discloses a high-voltage narrow-slit pressurized arc extinguishing device, including an arc extinguishing shell, a mounting frame, an arc extinguishing assembly, and two first gas generating components. The bottom of the arc extinguishing shell is provided with a gas generating port, and the two first gas generating components are symmetrically arranged on both sides of the gas generating port. When the circuit breaker is tripped, the moving contact swings, causing the electric arc on it to enter between the two first gas generating components through the gas generating port. The arc extinguishing assembly is disposed on the mounting frame and is used to extinguish the electric arc between the two first gas generating components. A narrow slit is formed between the two first gas generating components, which makes the arc heat more concentrated, increases the arc voltage, accelerates the pyrolysis rate of the gas generating material, and generates more arc extinguishing gas per unit time, thereby improving the arc extinguishing effect.

The utility model discloses waste battery carbon powder separation equipment, and belongs to the technical field of waste battery treatment devices. Comprising a tubular furnace, an inert gas supply mechanism communicated with the tubular furnace and a volatile gas condensation and collection mechanism, a motor with an output shaft penetrating through the tubular furnace is arranged in the middle of the upper portion of the tubular furnace, a first auger blade is arranged on the lower middle portion of the output shaft of the motor, and the outer edge of the first auger blade is connected with a second auger blade; a motor is arranged to drive a first auger blade to rotate, and the first auger blade drives a second auger blade to rotate, so that when carbon powder is separated by using a high-temperature pyrolysis method, the first auger blade can drive black powder which is placed in a tubular furnace and is close to the middle to move outwards, and the second auger blade can drive black powder which is placed in the tubular furnace and is close to the outside to move inwards; therefore, the black powder can be rapidly and uniformly heated, and the pyrolysis speed of the black powder is increased.
