Problems solved by technology

However, it is impossible to realize the continuous feeding and discharging of materials under hot conditions, and manual distribution and discharging are required
Moreover, it is necessary to wait for the device to cool down before feeding the material after discharging, which increases the failure rate of the equipment and reduces the processing capacity

Embodiment

[0111] Coal particles with a particle size of 10 mm to 20 mm provided by PetroChina were used as raw materials (see Table 1 for coal quality analysis data). The material is first stored in the feeding bin 5, the slide valve 6 is opened, and then the material slides down from the feeding chute at the feeding bin 5 into the reaction chamber 8 under the action of gravity.

[0112] Under the rotation of the feeding screw 3b and the drive of the transmission bearing 9, the coal particles are evenly distributed on the material plate 4 and move horizontally to the discharge end at the same time. Control the speed of feeding screw 3b and transmission bearing 9, make the material thickness on the whole material plate 4 be 200mm, then close the gate valve 6. Turn on the radiant tube combustion system. When the material temperature is lower than 280°C, control the heating rate of radiant tube 2 to 55°C / min; when the material temperature is higher than 280°C, control the heating rate of r...

Abstract

The invention relates to a low-temperature continuous heat treatment fixed-bed reactor and a method thereof. The reactor of the present invention has a feed inlet, a shell, a reaction chamber, and a feed outlet. The feed inlet is located above the feed outlet. The feed end and the discharge end, the feed screw is below the feed port and the upper part of the feed end, the discharge screw is above the discharge end, and the discharge end is above the discharge port; the feed screw includes the center screw and the left, The right helical blade, the central screw crosses the left and right helical blades, the left and right helical blades are perpendicular to the center line of the central screw to form axisymmetric, and the spacing is 1 / 3 to 1 / 2 of the diameter of the feed port. The invention can realize continuous material feeding and discharging under the condition of hot state, has low equipment failure rate and high economic benefit.

Description

technical field [0001] The invention relates to the field of heat treatment reactors, in particular to a low-temperature continuous heat treatment fixed-bed reactor and a method for pyrolyzing materials using the fixed-bed reactor. Background technique [0002] Coal and other carbon-containing organic component materials (such as domestic garbage, biomass, sludge, oil sludge, waste tires, waste plastics), can produce solid, liquid and gaseous products after heat treatment, and these products are made into recyclable and easy-to-use It is an energy form that is easy to transport and store, and can be used for thermal power generation or as a raw material for chemical and other industries. The above heat treatment process includes carbonization, gasification, pyrolysis, liquefaction or other related processes. [0003] Among them, pyrolysis is a kind of heat treatment process, and there are many kinds of reactors used, including moving bed, fixed bed, rotary kiln and fluidize...
