Background

Solid waste refers to solid, semi-solid and gaseous items, materials disposed in containers that are discarded or discarded without losing their original value of use produced during manufacturing, life and other activities, as well as items, materials regulated by law and administrative laws and regulations that are incorporated into waste management. Liquid waste that cannot be discharged into the body of water and gaseous substances placed in containers that cannot be discharged into the atmosphere are generally classified as solid waste management systems, due to the greater hazard they have.

The technology for disposing the hazardous waste by using the cement kiln is adopted in developed countries such as America, Canada, Japan and the like as early as seventy years, the research and development of the technology for disposing the hazardous waste by burning by using the rotary cement kiln in China starts from the beginning of the 90 s, the technology breaks through in recent years, the countries gradually perfect relevant technical specifications, and the prior examples of the operation of the technology for disposing the hazardous waste by using the cement kiln in many cities in China at present have a great deal of experience for reference.

The current popular solid waste incineration technology comprises an incinerator technology and a cement kiln cooperative disposal technology, and has the following problems:

(1) the incinerator technology is greatly influenced by the properties of solid wastes, the skin formation phenomenon is frequent, and the operation rate is low; most of the cooperative treatment technologies of the cement kiln adopt a direct adding mode, and the impact on the cement kiln is increased due to heat value or moisture, so that the cement production is not easy to control, and the quality or the yield of clinker is reduced.

(2) When the waste is incinerated in the separate incinerator, the incinerator slag needs to be treated separately or buried, a large landfill site needs to be matched, the heat is brought out greatly, and energy is wasted.

(3) Waste is directly thrown into a cement kiln decomposing furnace or a kiln head for burning, because cold solid waste is thrown, a large amount of heat is absorbed after the waste enters the decomposing furnace, the burning working condition is unstable due to the fact that the thrown amount is too large, and when the thrown particles are too large, the decomposition reaction in the kiln is incomplete, and the burning of cement clinker is influenced.

(4) Waste is burnt in the incinerator, and due to various physical forms, the waste is easy to accumulate in the incinerator or form rings in a kiln, so that the burning time is prolonged, the heat energy utilization rate is reduced, and the production efficiency is further reduced.

At present, from the actual production situation of an enterprise in which a cement kiln cooperative disposal project is built, the cement enterprise is unwilling to influence clinker production due to solid waste addition on the premise of pursuing high-quality clinker and high operation rate, the solid waste treatment capacity is extremely limited, the actual requirement of solid waste treatment cannot be met practically, and the current situation needs to be changed urgently.

By using the pre-combustion device to be matched with the cement production mode, the contradiction between the clinker production quality and the solid waste adding amount can be further solved, the solid waste is added in a large amount under the condition of stable production, but various environmental protection indexes need to be monitored at any time, the cost input and the operation complexity of enterprises are increased, and the popularization and the promotion are not facilitated.

It should be noted that although the specific position of the first power output component is not shown in the drawings, the understanding of those skilled in the art on the technical solution is not affected, and the first power output component (such as a hydraulic system, an electric system, etc.) is arranged at a certain position outside the furnace body 1, and is capable of driving the push rod and the push head to make linear motion, which is easy to implement for those skilled in the art, and no creative work is required, so the first power output component is omitted in fig. 2 in the present embodiment.

As shown in fig. 4 and 5, on the basis of the structure given by the above cleaning mechanism, the present embodiment is further designed to design both the pushing head 61 and the pushing rod 62 as hollow structures, a plurality of air holes 63 are arranged on one side of the pushing head 61 away from the pushing rod 62, the air holes 63 are communicated with the output port of the compressed air output device through the passage formed by the hollow structures in the pushing head 61 and the pushing rod 62, specifically, the pushing head 61 is communicated with the hollow part of the pushing rod 62 to form an air passage, the compressed air output by the compressed air output device is ejected through the air holes 63 after passing through the air passage, the compressed air not only can play a certain role of cooling the pushing rod 62 and the pushing head 61, prolonging the service lives of the pushing rod 62 and the pushing head 61, but also the compressed air ejected from the air holes 63 can play a better role of blowing the waste in front of the pushing head 61, so as to achieve the effects of agglomerating, overlapping, compressing and scattering, simultaneously in the moment that the pushing head 61 pushes the waste down from the incineration platform 5, the material raising effect can be played, so that the waste falls on the incineration platform on the next layer more loosely, and the more thorough combustion can be realized on the incineration platform on the next layer more sufficiently and quickly, the combustion time is shortened, and the combustion efficiency is improved.

Because the waste is easy to fall into a relatively concentrated area when falling from the upper layer of the incineration platform to the lower layer of the incineration platform, the waste is very serious in agglomeration and overlapping and is not beneficial to the combustion of the waste, in order to enable the waste on the incineration platform to be combusted more quickly and sufficiently, the flow aiding mechanism 7 is designed in the embodiment, and a specific structure of the flow aiding mechanism 7 is provided, as shown in fig. 3, the flow aiding mechanism 7 specifically comprises a swing rod 71, a swing head 72 and a second power output part (not shown in the figure), the swing rod 71 is linked with an output rotating shaft of the second power output part, the swing head 72 is fixed at the lower end of the swing rod 71, the swing rod 71 and the swing head 72 swing back and forth under the action of the second power output part, the second power output part is arranged outside the furnace body 1, and the influence of high temperature in the furnace body on the second power output part is effectively reduced, the second power output component can be a hydraulic system, certainly can also be an electric system or a pneumatic system, the swinging amplitude and the frequency of the swinging head 72 can be adjusted through the second power output component, and the waste is scattered by the swinging head 72 swinging back and forth, so that the waste can be combusted more sufficiently. It should be noted that, in order to prevent the swing head 72 from interfering with the push head 61, it is conceivable and easy to implement to set the lowest height (bottom to lowest point) of the swing head 72 higher than the upper surface of the push head 61, of course, the design can also be such that when the swinging head 72 and the swinging rod 71 move, the pushing head 61 stops at the position tightly attached to the inner wall of the furnace body, at this time, the pushing head 61 does not influence the movement of the swinging head 72 and the swinging rod 71, once the scattering work of the swinging head 72 and the swinging rod 71 is finished, the swinging head 72 and the swinging rod 71 can stay at a higher point (a position with larger swinging amplitude) to ensure that after the waste combustion lasts for a certain time, when the pushing head 61 pushes the waste down from the incineration platform 5, the swinging head 72 and the swinging rod 71 do not influence the movement of the pushing head 61, therefore, the cleaning mechanism and the flow assisting mechanism cannot interfere with each other, and the push head 61 automatically returns to the position close to the inner wall of the furnace body after pushing.

It should be noted that the first power output part of the cleaning mechanism 6 and the second power output part of the flow assisting mechanism 7 may be different controls of the same hydraulic system/electric system/pneumatic system, or different hydraulic system/electric system/pneumatic system, the cleaning mechanism 6 realizes the reciprocating linear motion under the action of the first power output part, and the flow assisting mechanism 7 realizes the oscillating motion under the rotation action of the second power output part, such power output control and transmission are easy to be realized by those skilled in the art, without any creative work, and therefore, specific positions and connection relationships of the first power output part and the second power output part are not shown in the drawing, which is clear to those skilled in the art.

The existing layered combustion mode usually does not adopt an external thrust mode to realize the layered combustion of wastes, but designs an inclined combustion platform or a combustion platform with an automatic overturning function, and the combustion platform has two problems, namely, the combustion time of each layer is uncontrollable, the time of the wastes staying on the combustion platform cannot be estimated and controlled due to the complex and various types of the wastes, so that the combustion time is uncontrollable, and the wastes are adhered on the combustion platform and are not easy to drop due to the properties of the wastes or the property change generated after the combustion. Above-mentioned problem has been solved well in this application, add the design that pushes away the head through the push rod, the problem that the discarded object layering dropped has been solved well, and can control the burning time of discarded object on burning the platform well, and add the design of pendulum rod through the yaw, can break up the discarded object, make the discarded object more abundant, burn high-efficiently, effectively improve combustion efficiency, shorten the actual measurement of burning time according to a large amount of inventors, the structural scheme of this application design, burning time can shorten more than 30%.
