Description

Biomass flat die particle automatic molding system

technical field

The invention belongs to the technical field of biomass fuel preparation, in particular to an automatic molding system for biomass flat die particles.

Background technique

The development of foreign briquette fuels is divided into three stages: from the 1930s to the 1950s is the stage of research, demonstration, and cross-introduction, and the focus of research is to replace fossil energy; the second stage is from the 1970s to the 1990s. The impact of fossil energy on the environment has been generally paid attention to, and interest in a large amount of renewable biomass energy has been developed, and research on biomass compact briquette fuel has been carried out. A relatively large number of biomass densified briquette fuels are used; from the late 1990s to the present, it is the third stage. First, the research work on large-scale utilization was carried out led by Denmark. The famous Danish energy investment company BWE took the lead in developing the first biomass fuel. Densified briquette fuel power plants, followed by Sweden, Germany, Austria and other countries have carried out research on the use of biomass compact briquette fuel for power generation and as boiler fuel. At present, Denmark has established 130 power plants, and the United States has built bark molding fuel processing plants in 25 states, producing more than 300 tons of fuel per day. However, some countries in Europe such as Denmark, Sweden and Austria have the fastest development of bio-briquettes. For example, the per capita fuel consumption of biomass densification in Sweden reaches 160kg/year. There are nearly a hundred biomass compact briquette fuel processing plants in Europe. Farmers use straw as raw material, and processing plants near cities use wood chips as raw material.

The research and development of biomass densification technology in my country started relatively late. Since the "Seventh Five-Year Plan", some domestic research institutes and enterprises have begun to study the biomass compact particle molding machine and the theory of biomass molding. Around 2000, some units successively developed and produced several different specifications of biomass pellet forming machines and carbonization units, including mechanical stamping pellet molding machines, hydraulically driven pellet molding machines, electric heating screw pellet molding machines, etc. However, these devices have some disadvantages such as serious wear of the forming cylinder and the screw shaft, short life, and high power consumption. In the 21st century, the country began to pay attention to the development of various renewable and clean energy sources. Biomass briquettes have also entered a good development stage. Granular and small cube briquettes have also attracted great attention. At present, many domestic enterprises, tertiary institutions, and scientific research institutes have successfully developed extrusion, hydraulic impact, and screw-type fuel production equipment, and are widely used in heating furnaces, boilers, and mechanism charcoal production. Since the 1980s, our country has introduced the screw propulsion type straw granule forming machine, and dozens of research institutes and production enterprises have invested in the research, development and utilization of briquetting fuel technology. At present, relatively mature technologies include: screw extrusion molding, piston extrusion molding, environmental extrusion molding, flat die extrusion molding, etc.

At present, there are few such complete sets of integrated equipment at home and abroad, most of which are single compression molding equipment, and the most common compression molding equipment mainly includes screw extrusion pellet molding machines, piston stamping pellet molding machines and Pressure roller pellet forming machine.

The screw extrusion pellet molding machine is the earliest pellet molding machine developed and applied. It relies on external heating to form the sleeve to keep the molding temperature between 150 and 300°C. The screw is used to push and extrude the biomass. The lignin and cellulose in the biomass are softened and densified into fuel lumps. The molding machine has the advantages of stable operation and continuous production of flammable molding fuel, but has the disadvantages of high moisture content requirements of raw materials, short service life of molding parts, and high energy consumption.

Piston stamping granule molding machine generally does not need external heating, and relies on the reciprocating motion of the piston to realize the compression molding of biomass raw materials, and is usually used to produce solid rod or block fuel. According to the driving type, the piston stamping pellet molding machine can be divided into two types: mechanical type and hydraulic type. The former uses the energy stored in the flywheel to drive the stamping piston through the crank railing mechanism to compress the raw material; the latter uses the energy provided by the hydraulic cylinder. The pressure drives the stamping piston to stamp the biomass into shape. Piston stamping pellet molding machine has the advantages of long service life of molding parts and low energy consumption, but it also has disadvantages such as poor machine operation stability, high noise, and serious lubricating oil pollution.

The basic working parts of the pressure roller granule forming machine are composed of a pressure roller and a pressure die. The pressure roller can rotate around its own axis, and the outer periphery is processed with teeth and grooves, which are convenient for the material to be pressed in and prevent slipping. The pressure mold is designed with certain Number of forming holes. Its working principle is: under the action of the pressure roller, the biomass raw material entering between the pressure roller and the die is squeezed into the forming hole and then extruded, and is cut into a certain length of molded fuel at the discharge port. . According to the different structures, the pressure roller granulator can be divided into flat die granulator and ring die granulator, and the ring die granulator can be divided into horizontal and vertical models.

Generally speaking, some progress and achievements have been made in domestic research on biomass flat die molding, but there are still some problems in the development method, process flow and overall matching performance analysis of equipment. (1) The theoretical foundation of flat die forming is weak, and the research on the forming characteristics and mechanism of biomass is not systematic and in-depth. At present, there is no development and application of biomass flat die technology and equipment; (2), the main components and equipment are severely worn , short maintenance cycle, high energy consumption, etc., and the research on integrated and automated biomass flat die molding is still immature, and the connection between flat die molding and other equipment such as drying equipment and crushing equipment is not very good; (3) 1. Flat die molding lacks diversity in molds, and it is difficult to meet the needs of different biomass utilization equipment; (4) Overseas biomass flat die compression molding technology is relatively mature, and some countries such as Northern Europe have formed a large industrial scale, but the equipment It is complicated, the cost is high, and the applicable raw material is mainly forestry biomass, which is not suitable for China's national conditions.

The feed inlet of the drier 10 is provided with an upper The feeder 9; the dryer 10 is provided with a first current sensor 17, a first humidity sensor 18 and a first temperature sensor 19.

Drying is the primary link in biomass energy pretreatment. The heat source for dryer 10 is provided by biomass boiling gasifier 12, which uses biomass as fuel instead of fossil energy. The hot air generated by the fluidized gasification furnace 12 is distributed through the settling chamber 11 and the temperature of the flue gas is controlled at about 350 degrees, and then enters the dryer 10 . According to the real-time monitoring of the first temperature sensor 19 and the first humidity sensor 18 in the drier 10, the automatic control of the operation of the fluidized gasification furnace 12 can be realized, so that it can provide the drier 10 with the corresponding temperature and total amount according to the requirements of the general program. hot air; the automatic control of the dryer 10 operation can make the dryer 10 dry the biomass raw material to the appropriate moisture with the highest heat utilization rate under the requirements of the general program, and according to the real-time monitoring of the first current sensor 17, if If the current is small, that is, the drying operation is slow and the drying time is long, the operation speed of the crushing part, material conveying part, forming part and cooling and drying separation part should be lowered or the operation should be suspended, which can save more energy. On the contrary, increase the speed of other parts. Part of the operating speed; in order to ensure that the exhaust air temperature is 80 °C when the inlet air temperature is 350 °C, the operation mode of the first current sensor 17 in the dryer 10 is: when the control center detects that the exhaust air temperature is higher than 80 °C, the The driving motor of the dryer 10 issues a command to reduce the rotational speed, and the residence time of the material in the drying equipment increases, thereby improving the heat utilization efficiency of the drying equipment.

The crushing part includes a pulverizer 1 and a first cyclone separator 2, the feed port of the pulverizer 1 is connected with the discharge port of the dryer 10, and the discharge port of the pulverizer 1 is connected with the feed port of the first cyclone separator 2; The pulverizer 1 is provided with a second current sensor 20 .

The dried materials are first crushed by the pulverizer 1. In view of the relatively large difference in moisture content in the raw materials and the unfixed types of pulverized materials, a combined biomass cutting, kneading and pulverizing equipment with good material applicability and moisture applicability has been developed. Fan blades are installed on the main shaft, which can blow the material out of the crushing chamber at a certain wind speed. The first cyclone separator 2 is no longer equipped with a separate fan, so the resistance is small and the efficiency is high. The pulverized materials are further separated and collected by the first cyclone separator 2, and the collected unqualified materials are recycled again. Through the real-time monitoring of the pulverizer 1 by the second current sensor 20, if the current is too large, it is known that the material is not easy to pulverize and it takes a long time to pulverize, so the operation of the drying part, material conveying part, forming part and cooling, drying and separating part will be lowered Speed up or suspend work, which can save more energy, and vice versa, increase the speed of other parts.

The molding part comprises a feed mixer 4, a water tank 13 and a particle molding machine 14, and the water spray nozzle of the water tank 13 stretches into the feed hopper 16 of the feed mixer 4, and the outlet of the feed mixer 4 is connected to the particle The feed port of the molding machine 14 is connected; the feed hopper 16 is provided with a second temperature sensor 21 and a second humidity sensor 22 , and the waste heat outlet of the fluidized gasifier 12 is connected with the feed hopper 16 . The material conveying part is a screw conveyor 3, the discharge port of the first cyclone separator 2 is connected with the feed port of the screw conveyor 3, and the discharge port of the screw conveyor 3 is connected with the feed hopper 16 of the feeding agitator 4 .

The screw conveyor 3 can adjust the production capacity of the screw conveyor 3 according to factors such as the diameter of the crushed material. After the material is separated by the first cyclone separator 2, it enters the feeding mixer 4 through the screw conveyor 3, and the powdery material After adding water in the feed hopper 16, it is adjusted to a moisture content of 12-30%. Water is pressurized by a booster pump (water pressure is 0.1MPa) in the water tank 13, and is sprayed into the feed agitator 4 by the water spray pipe, so that the moisture content of the material reaches 12-30%. After being evenly stirred in the feeding mixer 4 and meeting the molding process conditions, the material is sent to the pellet molding machine 14 for compression molding. The powdery material is molded in the pellet molding machine 14 .

Through the real-time monitoring of the second temperature sensor 21 and the second humidity sensor 22, temperature adjustment and water addition process control can be realized, such as controlling the amount of hot gas from the boiling gasifier 12 to the feed hopper 16, such as the original moisture content of the biomass is low According to the optimum moisture content required by the forming process, a certain amount of water can be added to the unformed biomass after crushing to meet the requirements of the forming process.

The cooling and drying separation part includes a cooling drier 6, a discharger 15, a second cyclone separator 7 and an induced draft fan 8, and the feed inlet at the top of the cooling drier 6 is connected with the discharge port of the particle molding machine 14 through a hoist 5, The discharge port at the bottom of the cooling drier 6 is connected with the feed port of the unloader 15, and the crushed material outlet at the top of the cooling drier 6 is connected with the feed port of the second cyclone separator 7, and the outlet of the second cyclone separator 7 The air port is connected with the suction port of the induced draft fan 8; a third temperature sensor 23 is provided in the cooling dryer 6, and a pressure sensor 24 is provided in the unloader 15.

Since the temperature of the granular fuel at the discharge port of the pellet forming machine 14 is about 60-70°C and the moisture content is 12-25%, the hardness at this time is low and it is difficult to store and transport, so the granular fuel needs to be cooled and dried. The molded fuel is sent to the cooling dryer 6 by the bucket elevator 5, and the conveying capacity of the elevator 5 depends on the value of the line load (the weight of the material per unit length) and the lifting speed. The granular fuel is cooled and dried by cold air in the cooling dryer 6 and then falls into the unloader 15 to complete the separation of the granular fuel and the unformed powder. The working principle of the cooling dryer 6 is that the hot granular fuel directly enters the cooling dryer 6 through the inlet, and falls onto the discharge grid at the bottom. Driven to move relative to each other, it starts to discharge shaped pellet fuel. Under the action of the induced draft fan 8, the crushed materials in the cooling dryer 6 are pumped to the second cyclone separator 7, and the second cyclone separator 7 separates and collects the crushed materials, and then recycles them for reuse.

The invention includes a complete set of biomass molding equipment and production process including biomass drying, crushing, transportation, moisture adjustment, compression molding, cooling, drying and separation, etc., and realizes the integrated operation of the whole system; according to the feed amount of raw materials, Changes in conditions such as crushing amount, heat supply and output, and material moisture content automatically adjust the operating conditions of the equipment to realize automatic operation, making the system run continuously and stably, and forming a large-scale production.

The main detection functions of the present invention are: the control center can carry out online detection of the moisture content of the biomass before entering the pellet forming machine 14, online monitoring of the electric current of the pulverizer 1 and the pellet forming machine 14, and the online monitoring of the hot air before entering the drying equipment. On-line detection of the temperature of the discharged moisture, and on-line detection of the temperature and humidity of the feed bin 16.

The main adjustment functions of the present invention include: stepless regulation of the feeding and blasting of the fluidized gasifier, stepless regulation of the feeding belt conveyor of the dryer 10, stepless regulation of the air distribution motor, and stepless regulation of the dryer 10 drag motors for stepless adjustment.

The control process is as follows: when the control center detects that the moisture content of the molding material is higher than the required moisture content, it can call the hot air control program at the same time to increase the content of high-temperature flue gas. The temperature must be kept at the set temperature, and at the same time reduce the drag motor speed, so that the heat utilization rate of the dryer 10 is maintained at a relatively high level; if the moisture content is lower than the set value, then adjust in the opposite direction, start the water addition program, and increase the moisture content of the raw material to meet the requirements of the molding equipment for raw materials. Moisture requirements. When the detection center detects that the operating current of the main motor of the pulverizer 1 or the particle molding machine 14 is greater than the set value, the speed of the feed belt of the dryer 10 is reduced to reduce the amount of feed, and the air volume of the fluidized gasifier 12 is also corresponding decrease, the dryer 10 drives the motor speed to increase.

While drying, the control center detected an increase in the exhaust gas temperature of the dryer 10, and the control center issued a command to reduce the speed of the drive motor to increase the drying time of the raw material, so that the exhaust temperature of the dryer 10 was maintained at the designed 80°C. The drying efficiency of the dryer 10 is maximized. The control process of the operating parameters of the drying part is as follows: when the moisture content of the added material increases, under the action of the control center, the amount of high-temperature flue gas provided by the fluidized gasifier 12 will also correspond accordingly. If the drying time of the material remains unchanged, the exhaust gas temperature will rise. High, its drying efficiency will decrease. The drying control subroutine can better solve this problem. When the control center detects that the exhaust gas temperature of the dryer 10 is higher than the set 80 °C, the drying subroutine of the control center starts, and sends an instruction to reduce the motor speed and increase the drying time of the material. The high-temperature flue gas can fully exchange heat with the material. As a result, the exhaust gas temperature is lowered to ensure that the dryer 10 works at a higher efficiency.

The second humidity sensor 22 and the pressure sensor 24 continuously measure the change of raw material moisture and molding pressure during the production process of the equipment, and adopt microcomputer control to automatically adjust the water spray rate of the water tank 13 of the feeding system and the feeding agitator 4 feeding twist according to the measured value. Long feeding speed, so as to keep the granule molding machine 14 always working under the best molding raw material moisture and molding pressure, to achieve the most economical operation state. The moisture control accuracy is within ±3%, and the molding pressure control accuracy is within ±1Mpa.

In summary, the present invention adopts an integrated automatic control system to realize the automatic operation of each link of biomass forming, which reduces manual operations, ensures that the system automatically operates under optimized working conditions, and has low energy consumption and labor costs. The drying process adopts boiling combustion technology to provide heat source, does not consume traditional energy, and the heat utilization rate of the equipment can reach more than 60%.

The present invention integrates biomass drying, crushing and flat die compression molding, and cooling and drying. The heating plate forms a high-efficiency airflow organization for drying. The moisture content unevenness of the dried material is less than 3%, and the moisture content can be adjusted flexibly. The heat utilization rate of the equipment is not less than 60%. The dried biomass enters the pulverizer 1, and is cut and pulverized by a biomass cutting and kneading mill with good balance, small vibration, high pulverization efficiency and low energy consumption, so that the particle size is 3-6mm to meet the next step of compression forming. The pulverized biomass enters the granule forming machine 14 through the material conveying part, and forms a biomass briquette fuel with a density of 0.9-1.3 g/cm3 after compression. Finally, it is cooled by the cooling drier 6 to further reduce the moisture content of the briquette. The solid line in the figure is the biomass raw material molding route, and the dotted line is the hot air and flue gas route.
