Thermal desorption regeneration tower equipment for saturated activated aluminum oxide pellets

Abstract

The invention discloses thermal desorption regeneration tower equipment for saturated activated aluminum oxide pellets. The thermal desorption regeneration tower equipment comprises a tower body, an automatic swinging and hinging device, an automatic sliding emptying device, a buffering porous gas homogenizing cover, an explosion-proof blow-off valve and a gas locking and discharging flap valve, wherein the tower body comprises a cylinder body, a cone and a bracket; a gas outlet pipe is arranged on the cylinder body; an outlet section temperature thermocouple is arranged on the gas outlet pipe; temperature thermocouples are respectively arranged at an upper part, a middle part, a middle lower part and a lower part in the cylinder body; and a regeneration discharge section temperature thermocouple is arranged on the cone. According to the invention, by controlling a feeding amount, the inner temperature of the gas outlet pipe is controlled; and the temperature thermocouples are arranged on the upper part, the middle part, the lower middle part and the lower part in the cylinder body respectively, so the temperatures of a fluidization preheating section at the upper part, a desorption material bed low-temperature section at the middle part, a desorption material bed medium-temperature section at the middle lower part and a desorption material bed high-temperature section at the lower part in the cylinder body and a regeneration discharging section in the cone are respectively detected, the blanking speed of the automatic sliding emptying device is controlled, the thorough thermal desorption is guaranteed, and the technical conditions of regeneration are met.

Description

technical field [0001] The invention relates to the technical field of resource recovery and utilization, in particular to a thermal desorption regeneration tower equipment for saturated activated alumina pellets. Background technique [0002] At present, for the treatment of saturated activated alumina pellets, they are generally incinerated at high temperature as harmful solid waste, and the incinerated alumina powder is often used to make ceramic materials, which causes the porous structure still preserved in the material to be sintered and lost, and the atmosphere serious pollution. In the prior art, for the regeneration treatment of saturated activated alumina pellets, it is necessary to use a liquid collection tank to collect the liquid on the processed saturated activated alumina pellets to prevent it from dripping into the processing equipment, but this liquid collection The tank often takes up a large volume and occupies the space of the processing equipment. At th...
