Description
Technical field
The utility model relates to solid material feeding-back technical field, particularly a kind of material-returning device that is applicable to carbonaceous material.
Background technology
The basic function of material-returning device is that high temperature carbonaceous solid particulates that cyclone separator is separated is sent into continuously and in burner hearth, burnt away or gasify, and prevents that flue gas from playing a reversed role into cyclone separator simultaneously.Its basic principle is exactly from bottom, to send into the fluidisation that returning charge wind is realized carbonaceous material, under feed pipe and drainage conduit differential pressure action, material is sent into burner hearth.
Existing material-returning device is mostly U-shaped material returning device, because returning charge amount in actual production is in constantly changing, the U-shaped material returning device of transmission cannot guarantee that the coupling of returning charge wind and returning charge amount causes feed blocking and slagging scorification in material returning device, causes material returning device normally to work.
Utility model content
For solving the technological deficiency of existing material-returning device, the utility model is taked following technical scheme:
A kind of material-returning device that is applicable to carbonaceous material, it is characterized in that level-sensing device 3 is loaded on the sidewall of feed pipe, feed pipe is installed on top, returning charge chamber, dividing plate is divided into two parts by returning charge chamber, drainage conduit is installed on returning charge chamber sidewall, air intake supervisor communicate with returning charge chamber through air intake transverse tube and air intake vertical tube, and scum pipe is installed on bottom, returning charge chamber.
The diameter of described feed pipe is 400～900mm, with what guarantee that carbonaceous material can be continuous, enters returning charge chamber.
Described air intake supervisor's diameter is 80～250mm, and the diameter of air intake transverse tube is 60～150mm, and the diameter of air intake vertical tube is 60～150mm, makes returning charge wind energy enter enough uniformly returning charge chamber.
The angle that described drainage conduit becomes with returning charge chamber 2 walls is 20～50 °, and the diameter of drainage conduit is 400～900mm, guarantees that carbonaceous material can discharge from drainage conduit smoothly.
The diameter of described scum pipe is 80～200mm, guarantees that bulk materials can discharge from scum pipe.
The distance of described level-sensing device and bottom, returning charge chamber is 3000～6000mm, guarantees the certain carbonaceous material of reservoir in feed pipe, avoids returning charge wind from feed pipe anti-channeling.
