Description

Distributed high efficiency, energy saving and environmental protection industrial kiln

technical field

The present application belongs to the technical field of industrial kilns, and more specifically, relates to a distributed industrial kiln with high efficiency, energy saving and environmental protection.

Background technique

In the ceramic industry, the common industrial kilns are mainly divided into two types: tunnel kilns and roller kilns. In these two industrial kilns, the kiln car loaded with the ceramic products to be fired will pass through the loading area, the preheating bin, the firing area, the cooling area, the unloading area, and then return to the loading area again, and so on. Complete the entire firing process. The main difference between the two industrial kilns is that the kiln car of the roller kiln relies on the rotation of the rollers to achieve forward movement, while the kiln car of the tunnel kiln has its own wheels and moves forward by dragging. However, during the forward movement of the kiln car, whether it is a tunnel kiln or a roller kiln, a kiln car collapse accident may occur, especially multi-layer kilns are more prone to such accidents. An accident of a kiln car will lead to the shutdown of the entire production line. Once production is stopped, the entire tunnel needs to be slowly cooled before the fault is cleared, and the entire tunnel needs to be slowly heated up after the fault is cleared. Therefore, the entire process of cleaning and restarting the production line will consume huge time, manpower, material and financial resources. . Therefore, how to avoid the shutdown of the entire production line due to the collapse of the kiln car is a difficult problem that all ceramic manufacturers must face.

In addition, the current common industrial kilns still have the reality of large investment, large carbon emissions, large land use, but relatively small production capacity. Specifically, first of all, to build an ordinary ceramic production line, at least 50 million yuan needs to be invested in equipment and workshops. The investment scale is large but the production capacity is small; secondly, a new ordinary ceramic production line needs about 50 acres of land, so large Large-scale land use is unsustainable when land is becoming more and more expensive; again, industrial kilns usually use gas when firing ceramic products, such as but not limited to natural gas, coal gas, heavy oil gas, etc. This method not only consumes a large amount of gas resources, but also produces a large amount of carbon dioxide emissions. Especially under the current environmental protection requirements of carbon neutrality, ordinary ceramic production lines will be strictly limited in production, and the old production lines with unqualified emissions will also be produced. will be gradually shut down.

Therefore, how to design an industrial kiln that is environmentally friendly and energy-saving, occupies a small area, has high output and has good safety has become an urgent problem to be solved in the field of ceramic industry.

The embodiments of the present application provide a distributed industrial kiln with high efficiency, energy saving and environmental protection.

Please refer to FIG. 1 and FIG. 2. In one embodiment, the distributed high-efficiency, energy-saving and environment-friendly industrial kiln includes several preheating chambers 100, several firing kilns 200, several cooling chambers 300, hoisting equipment (not shown), intelligent Ventilation system 900 and control system (not shown). Wherein, each preheating chamber 100 is set as a completely independent unit, and the preheating chamber 100 specifically includes a preheating chamber body (not shown) and a preheating chamber door (not shown in the figure) disposed at the opening of the preheating chamber body display), the preheating compartment door can be movably opened and closed to open or close the preheating compartment body. Each firing kiln 200 is also set up as a completely independent unit, and is spaced apart from the preheating bin 100; the firing kiln 200 specifically includes a kiln body (not shown), a kiln cover (not shown) and an intelligent electric flame Heating equipment 210, the kiln cover is set at the top of the kiln body, and can be movably opened and closed to open or close the kiln body. Firing of ceramic articles in the body. Each cooling bin 300 is also set up as a completely independent unit, and is spaced apart from the firing kiln 200 and the preheating bin 100; the cooling bin 300 specifically includes a cooling bin body (not shown) and a bin set in the cooling bin body. The cooling compartment cover of the mouth, the cooling compartment cover can be movably opened and closed to open or close the cooling compartment body. The hoisting equipment is arranged above the preheating chamber 100, the firing kiln 200 and the cooling chamber 300, such as but not limited to the beams of the workshop. The hoisting equipment is movable and used to separate the loading plates 700 on which the ceramic products are placed from the preheating chamber. The silo 100 , the firing kiln 200 and the cooling silo 300 are hoisted or loaded. The intelligent ventilation system 900 is respectively connected with the firing kiln 200, the preheating bin 100 and the cooling bin 300; the control system is electrically connected with the preheating bin 100, the firing kiln 200, the cooling bin 300, the hoisting equipment and the smart ventilating system 900 respectively, so as to realize Intelligent control of the above components.

Here, the control system can be regarded as a set of scheduling system for automatic production management, which can be used for the status collection of each production equipment, the issuance and reception of production scheduling instructions of production equipment, the time management of the current production process of production equipment, the current status of production equipment The management of the order execution steps of the process and the coordination between the order execution steps among the various production equipment can realize the planning of the production order execution steps according to different conditions, such as maximum production capacity, maximum energy saving or minimum production capacity, etc. Optimization of optimal production order execution steps. Specifically, the control system includes an intelligent control room 410 with a host computer and various information collection and transmission components, thereby forming a preheating bin fault management sub-system, a firing kiln automation management sub-system, a cooling bin automated management sub-system, and an intelligent ventilation management sub-system. Sub-system, hoisting automation coordination management sub-system, etc. Among them, the firing kiln automation management sub-system includes the heating management function of the intelligent electric flame. Of course, the industrial kiln also includes a loading area 510 and an unloading area 520. Correspondingly, the control system also includes an automatic loading management subsystem in the loading area and an automatic unloading management subsystem in the unloading area. In this way, through the intelligent scheduling of the control system, the production efficiency of the distributed high-efficiency, energy-saving and environmental-friendly industrial kiln can be greatly improved, thereby expanding the output and reducing the cost of ceramic products.

Based on this structural design, in this application, compared with the current common industrial kilns, this distributed industrial kiln with high efficiency, energy saving and environmental protection has the following advantages:

First, since the preheating bin 100, the firing kiln 200 and the cooling bin 300 are completely independent units and are distributed at intervals, these separate production equipment can run in parallel without interfering with each other, so the production personnel can Demand, arbitrarily expanding or shutting down a warehouse without affecting the normal production of the overall production line. For example, when a certain production equipment in the preheating warehouse 100, the firing kiln 200 and the cooling warehouse 300 is a bottleneck in production capacity, it can be independently increased. In this way, the production capacity can be significantly increased, and even the maximum release capacity can be achieved; of course, when a production equipment fails, it can also be stopped directly, and another similar production equipment can be directly used without affecting In this way, the whole production line can be completely avoided due to the collapse of the kiln car, and the production safety of the whole production line can be greatly improved. At the same time, using the technical solution of the present application, between the minimum production capacity and the maximum production capacity, flexible production capacity can be achieved.

Second, in the firing kiln 200, the intelligent electric flame heating device 210 arranged on the inner side wall of the firing kiln 200 is used for firing ceramic products. Electric energy is used for heating, such as but not limited to photovoltaic power, wind power, hydropower, nuclear power, biomass power and other renewable energy sources, so as to achieve the goal of zero carbon emissions during production, which has positive environmental protection significance.

Third, when the intelligent electric flame heating device 210 is used, the kiln cover of the kiln 200 is closed, that is, the intelligent electric flame heating device 210 is in a closed kiln body during heating, thereby greatly reducing the loss of heat energy; of course , the preheating bin 100 can also be sealed by the preheating bin cover, and the cooling bin 300 can also be sealed by the cooling bin cover, which is also beneficial to reduce energy loss; in addition, because the intelligent ventilation system 900 is respectively connected to the firing kiln 200 and the preheating bin 100 and the cooling bin 300, so the thermal energy of the firing kiln 200 during the cooling process can also be reused for the preheating of the preheating bin 100 and the drying of the drying tower 950 through the intelligent ventilation system 900. In other words, the kiln 200, the preheating chamber 100 and the cooling chamber 300 can be opened and closed, and the communication function of the intelligent ventilation system 900 can make the distributed industrial kiln very energy efficient.

It should be noted here that the distributed industrial kiln with high efficiency, energy saving and environmental protection is mainly used for the firing of ceramic products, and is especially suitable for the manufacture of foamed ceramics. Under the premise of advocating green energy-saving buildings, safe and environmentally friendly construction, as a new type of inorganic building material, foamed ceramics have the advantages of light weight, non-combustibility, heat preservation, heat insulation, waterproof and moisture-proof, etc., and can better meet the gradually increasing real estate Therefore, people pay more and more attention to the thermal insulation performance requirements of building materials. Usually, the partition board made of foamed ceramics should be a large board with a thick thickness but high strength and light weight. For example, referring to the wall standard of a general building, the thickness of the partition board is generally 10 to 15cm. The thickness of the partition board used in the northern region should be greater than 20cm, and its compressive strength should reach more than 6 MPa. Due to these high performance standards, if the common industrial kilns are used to fire foamed ceramics, it will lead to problems such as long firing time, high energy consumption, high carbon emissions, and low production capacity, which will lead to foamed ceramics. The cost is high and the market price is higher, which is not conducive to the market expansion of this environmentally friendly product. Specifically, in the comprehensive cost of foamed ceramics, about 1/3 is the energy cost, and about 1/3 is the cost of equipment depreciation and land use. In the present application, the distributed high-efficiency, energy-saving and environmentally friendly industrial kiln can increase the production capacity by at least 3 times or more with the same or even less investment and less land, and also has a significant energy-saving effect. Therefore, the use of this distributed high-efficiency, energy-saving and environmentally friendly industrial kiln for foamed ceramics can reduce the cost to about 400 yuan/cubic, and thus have more price advantages. Once foamed ceramic products have both price and performance advantages, It will be greatly beneficial to the market development of the green product with excellent performance.

The advantages of the distributed high-efficiency, energy-saving and environment-friendly industrial kiln compared with the currently common industrial kilns are described below with specific data. Wherein, Table 2 is a comparison table of the firing time of foamed ceramics of the currently common tunnel kilns, roller kilns, and the distributed high-efficiency, energy-saving, and environment-friendly industrial kilns of the present application. Table 1 is a comprehensive cost comparison table of the three-layer tunnel kiln, the roller kiln, and the distributed high-efficiency, energy-saving and environmental protection industrial kiln of the present application in terms of investment, land use, gas consumption, electricity consumption and production capacity. From Table 1 and Table 2, it can be seen that under the same or even less investment, less land, more environmental protection and more energy saving, the production capacity of this distributed high-efficiency, energy-saving and environmentally friendly industrial kiln can be increased by at least 3 times or more, while the cost is relatively low. lower.

It should be noted here that in Table 2, the firing time of foamed ceramics refers to the time difference between the product to be fired entering the tunnel/kiln and the fired product exiting the tunnel/kiln, which includes preheating time, firing time, cooling time time; since the preheating zone, firing zone and cooling zone of the tunnel kiln and roller kiln are integrated and linearly connected in series, the firing time is the maximum time value among these three times; in this distributed and efficient In the energy saving and environmental protection industrial kiln, since the preheating bin 100, the firing kiln 200 and the cooling bin 300 are independent and run in parallel without interfering with each other, it is possible to exchange space for time and save a lot of time. In Table 1, the comprehensive cost of foamed ceramics is calculated under the following conditions: gas price of 2.8 yuan/cubic meter; average electricity price of 1.1 yuan/kWh (weighted average of peaks and valleys of electricity); equipment depreciation according to national standards The rate of depreciation of equipment is allocated to cost.
