Description

Distributed high-efficiency energy-saving environment-friendly industrial kiln

Technical Field

The application belongs to the technical field of industrial kilns, and particularly relates to a distributed efficient energy-saving environment-friendly industrial kiln.

Background

In the ceramic industry, currently common industrial kilns are mainly divided into a tunnel kiln and a roller kiln. The kiln car loaded with the ceramic products to be fired passes through a loading area, a preheating bin, a firing area, a cooling area and an unloading area in sequence in the two industrial kilns, and then returns to the loading area again, so that the whole firing process is completed in a circulating way. The main difference between the two industrial kilns is that the kiln car of the roller kiln moves forwards by means of the rotation of the rollers, and the kiln car of the tunnel kiln is provided with wheels and moves forwards by means of dragging. However, in the process of forward movement of the kiln cars, the kiln cars of both tunnel kilns and roller kilns may collapse, particularly, the accidents of the multi-layer kilns are more likely to happen, and the accidents of any one kiln car in any one zone can cause the stop of the whole production line. Once production is stopped, the whole tunnel needs to be slowly cooled before the fault is cleared, and the whole tunnel needs to be slowly heated after the fault is cleared, so that huge time, manpower, material resources and financial resources are consumed in the whole process of clearing and restarting the production line. Therefore, how to avoid the shutdown of the whole production line caused by the collapse of the kiln car is a difficult problem which all ceramic production enterprises have to face.

In addition, the current common industrial kilns have the industrial reality of large investment, enlarged carbon emission, large land consumption scale and relatively small capacity. Specifically, firstly, a common ceramic production line is newly built, only equipment and a factory building need to be invested by at least 5000 thousands, the investment scale is large, and the productivity is small; secondly, a common ceramic production line needs 50 mu land for building, and large-scale land is difficult to continue under the condition that the land is more and more expensive; third, industrial kilns typically use gas, such as but not limited to natural gas, coal gas, heavy oil gas, etc., when firing ceramic products, the heating method not only consumes a large amount of gas resources, but also generates a large amount of carbon dioxide emissions, especially under the environmental protection requirement of carbon neutralization nowadays, a common ceramic production line is severely limited to produce, and old production lines with unqualified emissions are gradually shut down.

Therefore, how to design an industrial kiln which is environment-friendly, energy-saving, small in occupied area, high in output and good in safety becomes a problem to be solved urgently in the field of ceramic industry.

In order to explain the technical solutions provided in the present application, the following detailed description is made with reference to specific drawings and examples.

The embodiment of the application provides a distributed high-efficiency energy-saving environment-friendly industrial kiln.

Referring to fig. 1 and 2, in an embodiment, the distributed energy-efficient and environment-friendly industrial kiln comprises a hot bin 100, a plurality of firing kilns 200, a plurality of cooling bins 300, a lifting device (not shown), an intelligent ventilation system 900 and a control system (not shown). Each preheating bin 100 is a completely independent single body, each preheating bin 100 specifically includes a preheating bin body (not shown) and a preheating bin door (not shown) arranged at a bin opening of the preheating bin body, and the preheating bin door can be opened and closed movably to open or close the preheating bin body. Each sintering kiln 200 is also arranged in a completely independent single body and is distributed at intervals with the preheating bin 100; the firing kiln 200 specifically comprises a kiln body (not shown), a kiln cover (not shown) and an intelligent electric flame heating device 210, wherein the kiln cover is arranged at the top end of the kiln body and can be movably opened and closed to open or close the kiln body, and the intelligent electric flame heating device 210 is arranged on the side wall of the kiln body and is used for spraying electric flame to fire the ceramic product placed in the kiln body. Each cooling bin 300 is also arranged in a completely independent monomer and is distributed at intervals with the firing kiln 200 and the preheating bin 100; the cooling chamber 300 comprises a cooling chamber body (not shown) and a cooling chamber cover disposed at the opening of the cooling chamber body, wherein the cooling chamber cover can be opened and closed movably to open or close the cooling chamber body. The hoisting device is disposed above the preheating bin 100, the firing kiln 200 and the cooling bin 300, for example, but not limited to, on a cross beam of a factory building, and the hoisting device is movable and used for hoisting or loading the loading plate 700 on which the ceramic ware is placed out of or into the preheating bin 100, the firing kiln 200 and the cooling bin 300, respectively. The intelligent ventilation system 900 is respectively communicated with the sintering kiln 200, the preheating bin 100 and the cooling bin 300; the control system is respectively electrically connected with the preheating bin 100, the firing kiln 200, the cooling bin 300, the hoisting equipment and the intelligent ventilation system 900, so as to realize intelligent control of the above components.

Here, the control system can be regarded as a set of scheduling system for automated production management, and can be used for acquiring the state of each production device, issuing and receiving the production scheduling command of the production device, managing the time of the current production process of the production device, managing the command execution step of the current process of the production device, and coordinating the command execution steps among the production devices, so as to plan the production command execution step and optimize the optimal production command execution step according to different conditions, for example, according to the conditions of maximum capacity, maximum energy saving, minimum capacity, and the like. Specifically, the control system comprises an intelligent control room 410 provided with a host and various information acquisition and transmission components, and further forms a preheating bin fault management subsystem, a firing kiln automatic management subsystem, a cooling bin automatic management subsystem, an intelligent ventilation management subsystem, a hoisting automatic coordination management subsystem and the like, wherein the firing kiln automatic management subsystem comprises a heating management function of intelligent electric flame. Of course, the industrial furnace further includes a loading area 510 and an unloading area 520, and accordingly, the control system also includes an automatic loading management subsystem of the loading area, an automatic unloading management subsystem of the unloading area, and the like. Therefore, the production efficiency of the distributed high-efficiency energy-saving environment-friendly industrial kiln can be greatly improved through intelligent scheduling of the control system, so that the output is enlarged, and the cost of ceramic products is reduced.

Based on the structural design, compared with the common industrial kiln, the distributed high-efficiency energy-saving environment-friendly industrial kiln has the following advantages:

firstly, because the preheating bin 100, the calcining kiln 200 and the cooling bin 300 are completely independent and are arranged in a single body and distributed at intervals, and the independent production devices can run in parallel and do not interfere with each other, a producer can arbitrarily expand or stop producing a certain bin according to the capacity requirement without influencing the normal production of the whole production line, for example, when one production device in the preheating bin 100, the calcining kiln 200 and the cooling bin 300 is a capacity bottleneck, the number of the production device can be independently increased, so that the capacity can be obviously improved, and even the maximum capacity release can be realized; of course, when a certain production device breaks down, the device can be directly stopped and another similar production device can be directly used without influencing the operation, so that the condition that the whole production line stops due to the collapse accident of the kiln car can be thoroughly avoided, and the production safety of the whole production line is greatly improved. Meanwhile, by using the technical scheme of the application, the elastic capacity production can be realized between the lowest capacity and the maximum capacity.

Secondly, in the firing kiln 200, the ceramic product is fired by the intelligent electric flame heating device 210 arranged on the inner side wall of the firing kiln 200, the intelligent electric flame heating device 210 sprays electric flame, and the electric flame heating uses electric energy, such as but not limited to photovoltaic electricity, wind electricity, hydroelectric power, nuclear power, biomass electricity and other renewable energy sources, so that the purpose of zero carbon emission during production is achieved, and the positive environmental protection significance is achieved.

Thirdly, when the intelligent electric flame heating device 210 is used, the kiln cover of the sintering kiln 200 is closed, that is, the intelligent electric flame heating device 210 is in the closed kiln body when heating, so that the heat energy loss can be greatly reduced; certainly, the preheating bin 100 can be sealed by a preheating bin cover, and the cooling bin 300 can be sealed by a cooling bin cover, which is also beneficial to reducing energy loss; in addition, since the intelligent ventilation system 900 is connected to the firing kiln 200, the preheating compartment 100, and the cooling compartment 300, the heat energy generated during the cooling process of the firing kiln 200 can be reused for preheating the preheating compartment 100, air drying the air drying tower 950, and the like through the intelligent ventilation system 900. In other words, the firing kiln 200, the preheating bin 100 and the cooling bin 300 can be opened and closed and have the communication function of the intelligent ventilation system 900, so that the distributed efficient energy-saving environment-friendly industrial kiln can save energy.

It should be noted that the distributed efficient energy-saving environment-friendly industrial kiln is mainly used for firing ceramic products, and is particularly suitable for manufacturing foamed ceramics. Under the prerequisite of advocating green energy-conserving building, safe environmental protection construction now, foamed ceramics has advantages such as light, incombustible, heat preservation, thermal-insulated, dampproofing and waterproofing as a novel inorganic building material, can be better accord with the heat preservation heat-proof quality requirement of the real estate building material that improves gradually, therefore receives people's attention more and more. Generally, the partition wall plate made of foamed ceramics should be a large plate with a relatively large thickness, but high strength and light weight, for example, referring to the wall standard of general buildings, the thickness of the partition wall plate is generally 10 to 15cm, the thickness of the partition wall plate applied in northern areas should be more than 20cm, and the compressive strength should be more than 6 mpa. Due to these higher performance standards, if the foamed ceramics is fired by the common industrial kiln, the problems of long firing time, high energy consumption, high carbon emission, low productivity and the like will be caused, and further the foamed ceramics has high cost and higher market price, which is not beneficial to the market expansion of the environment-friendly product. Specifically, among the overall costs 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 application, the productivity of the distributed high-efficiency energy-saving environment-friendly industrial kiln can be improved by at least 3 times or more under the conditions of equal or even less investment and less land, and the distributed high-efficiency energy-saving environment-friendly industrial kiln also has a remarkable energy-saving effect. Therefore, the cost of the foamed ceramic manufactured by the distributed high-efficiency energy-saving environment-friendly industrial kiln can be reduced to about 400 yuan/cubic meter, so that more price advantages are achieved, and once the foamed ceramic product has price and performance advantages, the market development of the environment-friendly product with excellent performance can be greatly facilitated.

The following describes various advantages of the distributed high-efficiency energy-saving environment-friendly industrial kiln compared with the common industrial kiln at present by using specific data. Wherein, table 2 is a comparison table of the firing time of the foamed ceramics of the tunnel kiln, the roller kiln and the distributed high-efficiency energy-saving environment-friendly industrial kiln of the present application. Table 1 shows the comprehensive cost comparison table of the three-layer tunnel kiln, the roller kiln, and the distributed high-efficiency energy-saving environment-friendly industrial kiln of the present application in terms of investment, land use, gas use, electricity use, and capacity. From tables 1 and 2, it can be seen that under the conditions of equal or even less investment, less land use, more environmental protection and more energy saving, the productivity of the distributed efficient energy-saving and environment-friendly industrial kiln can be improved by at least 3 times, but the cost is relatively low.

It should be noted that, in table 2, the foamed ceramic firing time refers to the time difference between the time when the product to be fired enters the tunnel/kiln and the time when the fired product exits the tunnel/kiln, and the time includes the preheating time, the firing time and the cooling time; the preheating zone, the firing zone and the cooling zone of the tunnel kiln and the roller kiln are connected in series in an integrated linear mode, so that the firing time is the maximum time value of the three times; in the distributed high-efficiency energy-saving environment-friendly industrial kiln, the preheating bin 100, the firing kiln 200 and the cooling bin 300 are respectively independent and run in parallel without mutual interference, so that the time can be changed by using space, and the aim of saving a large amount of time is fulfilled. In table 1, the overall cost of the foamed ceramics is calculated under the following conditions: the price of the fuel gas is 2.8 yuan/cubic meter; average electricity price is 1.1 yuan/degree (weighted average value by electric wave peak and wave trough); and equipment depreciation is carried out according to the equipment depreciation rate of the national standard so as to be distributed to the cost.
