Embodiment 1

[0011] The method for treating waste after diketene rectification residue recovery and treatment is to add sawdust and veneer to the silo and continuously transport it to a high-speed crushing mixing reactor with a conveyor belt, and then continuously add diketene rectification residue to recover waste after treatment, wherein The mass percentage of sawdust and veneer is 50%. Finally, a relatively uniform mixture can be obtained through the outlet of the pulverizer for quantitative packaging, and the mixture can be directly used as fuel.

Embodiment 2

[0013] The treatment method of the waste after diketene rectification residue recovery and treatment is to put the boiler coal slag into the silo with a loader, and then use the conveyor belt to continuously add it to the high-speed mixing machine, and then continuously control the addition of diketene rectification residue recovery treatment The final waste, wherein the mass percentage of coal slag is 25%; finally, the mixed fuel with uniform particle size is obtained through the outlet of the mixer; this fuel can be further crushed into fine powder and clay at a ratio of 1:4 and can be used as a brick for internal combustion. use.

Embodiment 3

[0015] The treatment method of the waste after recovery and treatment of diketene distillation residue is to add coal into the silo and continuously transport it to the high-speed crushing mixing reactor with a conveyor belt, and then continuously add the waste after recovery and treatment of diketene distillation residue, including coal The mass percentage is 30%, and finally a relatively uniform mixture can be obtained through the discharge port of the pulverizer for quantitative packaging, and the mixture can be directly used as fuel.

[0016] As can be seen from the above examples, using the above-mentioned method for treating waste after rectification residue recovery and treatment of diketene can make diketene production enterprises no longer need to be troubled by waste disposal problems, and at the same time eliminate the traditional cooling of waste with water. The bonding of transportation equipment and environmental pollution effectively guarantee the orderly product...

Abstract

The invention relates to a processing method for wastes after recovery processing diketene rectification, which is realized by evenly mixing the wastes after recovery processing diketene rectification with an ignition substance. The invention is suitable for places, such as building materials bricks and tiles plants, gypsum manufacturing plants, calcination places and the like; and the wastes after being processed can be used as a new fuel.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a method for treating waste after recovery and treatment of diketene rectification residue. Background technique [0002] Diketene is an important chemical intermediate with a wide range of industrial applications. According to the Chinese Patent No.: 200610085796.0, the diketene distillation residue is hydrolyzed to effectively recover the active ingredients in the distillation residue, acetic acid and acetone, and the semi-solid paste produced is the diketene distillation residue recovery treatment after waste. The traditional treatment method for the waste after recovery and treatment of diketene distillation residue is: dilute it with water and cool it into a semi-solid jelly and then treat it as solid waste. The disadvantages of traditional treatment methods are: water pollution of cooling water; sticking, flowing, loading and unloading in the transportation proc...
