Abstract
Description
Technical Field
[0001] The invention relates to the technical field of waste cosmetics disposal, in particular to a method for co-disposing waste cosmetics with a cement kiln. Background Art
[0002] With the rapid development of social economy, cosmetics have become a common consumer product in real life. Cosmetic bottles are a must in the cosmetics industry. Cosmetic bottles refer to a container that can isolate gas from the outside temperature or isolate external bacteria. There are glass bottles, plastic bottles, and PET bottles. Among them, the production of glass bottles consumes the most energy. More and more brands have proposed empty bottle recycling plans. For the premise of environmental protection, cosmetic bottles are recycled.
[0003] Patent No. CN114273002B discloses an environmentally friendly treatment device for cosmetic production waste, which relates to the field of cosmetic production technology. The present invention includes a base, a lifting movable frame, a crushing mechanism, a receiving mechanism and a swinging mechanism. Both sides of the base are detachably connected with a lifting movable frame. The other side of the base side seat plate is equipped with a crushing mechanism and a feeding mechanism. The feeding mechanism is installed directly below the crushing mechanism, and the discharging end of the feeding mechanism is equipped with a receiving mechanism. The inside of the receiving mechanism is equipped with a swinging mechanism. The receiving mechanism provided by the present invention has two material frames that can be used alternately. When the crushed waste bottle debris is unloaded, the crushed material collection will not be affected, and it is convenient to unload while collecting the material, thereby improving the collection efficiency. In addition, a lifting movable frame is provided, which is convenient to push the device to move when it needs to be moved, and when it does not need to be moved, the base can be stably placed on the ground for use, which will not affect the stability of the device during normal use, thereby improving the applicability of the device.
[0004] Patent No. CN201910670083.8 discloses an environmentally friendly treatment device and method for cosmetic production waste, including a support frame, a storage barrel, a crushing box and a separation box, the storage barrel is arranged on the right side of the support frame, the top of the support frame is fixedly connected to the bottom of the separation box, the middle of the top of the separation box is fixedly connected with a conveying box, the left side of the bottom of the conveying box is connected to the top of the separation box, the right side of the top of the conveying box is fixedly connected to the bottom of the crushing box, and the right side of the top of the conveying box is connected to the bottom of the crushing box. The present invention relates to the technical field of cosmetic processing equipment. The environmentally friendly treatment device and method for cosmetic production waste integrates the sewage treatment system and the glass crushing device, which can not only reduce the consumption of water resources, but also save the expenditure of the enterprise. At the same time, the three-dimensional setting is adopted to save more space, make the utilization of resources more reasonable, and can also break up large condensates in the sewage to facilitate the treatment of sewage.
[0005] In order to ensure the quality of their products and prevent the used cosmetics bottles from being used by unscrupulous merchants, cosmetics manufacturers now need to recycle and crush them. Since there are often residual cosmetics attached to the inside of the bottles, they need to be further cleaned, which not only increases the consumption of water resources, but also increases the production costs of the companies. In addition, when unloading the broken waste bottle fragments, it is easy to affect the collection of the fragments, which makes it inconvenient to unload while collecting, resulting in low collection efficiency.
[0006] During the incineration process of discarded cosmetics, some toxic substances may be emitted, mainly including heavy metals such as lead, mercury, and cadmium: some discarded cosmetics may contain these heavy metals, which will be released when burned, polluting the surrounding environment and causing health hazards.
[0007] The above will cause environmental pollution. In addition, the addition of waste cosmetics may also affect the production efficiency and product quality of cement kilns. Summary of the invention
[0008] 1. Technical issues to be resolved
[0009] In view of the deficiencies in the prior art, the present invention provides a method for the coordinated disposal of waste cosmetics in a cement kiln, which reduces the generation of toxic gases during the incineration process and solves the technical problems of high resource consumption and difficulty in the recycling and treatment of waste cosmetics.
[0010] (II) Technical solution
[0011] To achieve the above objectives, the present invention is implemented through the following technical solutions:
[0012] A method for co-disposing waste cosmetics in a cement kiln, the operating steps of which are as follows:
[0013] The discarded cosmetics are conveyed into a shearing crusher, crushed to 80-100 mm, and then into a drum screen. The screened material enters a pulping tank to obtain material (a); the screened material enters a circulating shearing crusher, and after circulating crushing, it is conveyed into a cement kiln decomposition furnace for incineration; a metal solidifying dispersant is added to the material (a), and the mixture is fully stirred for 10-30 minutes, and the mixture is statically layered. The glass beads are at the top of the liquid and are scooped out using a screen for recycling. The remaining part is then pumped into a sludge tank, the sludge tank slide is opened, and after continuous operation for a certain period of time, the remaining part is conveyed into a cement kiln mixer, mixed and stirred in the mixer, and then conveyed to a plunger pump, which is pumped to the top of the cement kiln decomposition furnace for incineration and disposal. The slag produced by the incineration is mixed into the cement raw meal, and calcined in a rotary kiln to obtain cement clinker.
[0014] In the above technical solution, the specific drum screen is a 5mm drum screen.
[0015] In the above technical solution, the above-screen material is specifically cyclically sheared and crushed to less than 30 mm.
[0016] In the above technical solution, the specific addition amount of the metal solidification dispersant is 1-3%.
[0017] In the above technical solution, the specific preparation method of the metal curing dispersant is:
[0018] S1: Add 100-160 parts of hollow glass microspheres, 500-1000 parts of water, and 3-7 parts of acryl silane coupling agent into a reaction kettle according to weight proportions, stir at 70-80° C. for 100-200 min, filter, and dry to obtain acryl hollow glass microspheres;
[0019] S2: 20-30 parts of pentaerythritol tetrakis (3-mercaptopropionate), 300-400 parts of propylene glycol, 100-200 parts of propylene hollow glass microspheres, 0.002-0.05 parts of tetramercaptoporphyrin, and 2-6 parts of sodium ethoxide are stirred at 70-80° C. for 30-100 minutes to obtain the above-mentioned metal curing dispersant: hollow glass microsphere medium-immobilized 3-mercaptopropionate.
[0020] In the above technical solution, the specific acryl silane coupling agent is selected from one of KH-570 silane coupling agent and γ-methacryloxypropyltrimethoxysilane.
[0021] In the above technical solution, the material (a) is pumped into the sludge pool at a ratio of 20-30%.
[0022] In the above technical solution, the specific continuous operation time of the sludge tank slide is 50 to 60 minutes.
[0023] In the above technical solution, the specific mixing and stirring time in the mixer is 10 to 15 minutes.
[0024] In the above technical solution, the specific calcination temperature of the rotary kiln is 1200-1400°C.
[0025] Reaction mechanism:
[0026] The pentaerythritol tetrakis (3-mercaptopropionate), the propylene hollow glass microspheres, and the tetramercaptoporphyrin undergo a mercapto addition reaction to obtain a metal ligand, which can adsorb metal ions and solidify them on the hollow glass microspheres. At the same time, glycerol disperses the cosmetic residue and dilutes the metal ions therein to facilitate the absorption of the curing agent.
[0027] (III) Beneficial effects
[0028] 1. Most of the discarded cosmetic packaging contains heavy metals, and general treatment will cause pollution. However, this method can effectively utilize the discarded cosmetic packaging, reduce pollution to the environment, and at the same time improve the production efficiency of cement kilns and the quality of cement products. In addition, since cement production is a process with high energy consumption, the use of discarded cosmetics for calorific value recovery is also beneficial to energy conservation.
[0029] 2. Increase the fluidity of waste cosmetics: Mixing waste cosmetics with propylene glycol can increase the fluidity of waste cosmetics, making them easier to flow and mix during the cement production process, thereby improving cement production efficiency and the quality of cement products.
[0030] 3. Suppress the odor of discarded cosmetics: Discarded cosmetics may contain some decomposition products that produce unpleasant odors. Glycerol can inhibit the volatilization of certain components in discarded cosmetics, thereby reducing the generation of odors.
[0031] 4. During the incineration of discarded cosmetics, some toxic substances will be emitted, mainly including heavy metals such as lead, mercury, and cadmium. The present invention is conducive to the glass microbeads to chelate, solidify, and absorb the heavy metals and then take the heavy metals out of the system, thereby avoiding the emission of toxic substances.
