Technical Field

The utility model relates to an environmental protection field of handling especially relates to a wet material fast drying system of low energy consumption and method.

Background

In the field of environmental recovery, material drying treatment is a common means, and the treated material usually comprises biomass and sludge.

With the increasing demand for petroleum crisis and greenhouse gas emission reduction, finding alternative clean energy becomes the best strategy for solving the energy crisis and greenhouse effect. As biomass energy is used as chemical state energy, the biomass energy not only can generate electricity and supply heat, but also can be converted into liquid fuel and bio-based products, is the only energy source capable of replacing fossil fuels on a large scale, and technical experts and decision makers in mainly developed countries pay great attention to the development of the biomass industry. In recent years, along with intense disputes such as 'grain war by car', 'pedestrian lane crisis', 'environmental problem' and the like which are generated aiming at biomass energy industrial innovation, the world biomass energy industrial innovation begins to present new trends and characteristics.

The biomass energy is renewable clean energy and related chemical products produced by taking organic wastes such as agriculture and forestry and energy plants planted in marginal lands as raw materials and taking crop starch oil as a blending agent, can be extracted from agricultural and forestry products such as crop straws, sugarcane, corn, sugar beet, cassava, potatoes, cottonseeds, rapes, forest shrubs and the like, and organic wastes such as animal husbandry production wastes, industrial waste gas, municipal domestic wastes and the like, and is an environmentally-friendly renewable resource, such as fuel ethanol, biodiesel, biogas and the like. Therefore, energy crops are produced and planted, and the industry for producing biomass energy is the biomass industry or energy agriculture. The development of the biomass industry in China in recent years is a concrete embodiment of new agricultural functions (providing biomass energy), and is also hopeful to be a new growth point of modern agriculture, and the development of the biomass industry becomes a major measure for accelerating modern agricultural construction and developing rural circular economy in China.

Direct combustion of biomass: direct combustion can be roughly classified into 4 cases of stove combustion, boiler combustion, refuse incineration, and compact formed fuel combustion. In south China, many sugar mills use bagasse to generate electricity, 380 small generator sets are shared by two provinces, namely Guangdong province and Guangxi province, the total installed capacity reaches 800 megawatts, and some power plants exist in Yunnan province. Bagasse power plants are generally operated only during the press season. The European technology is introduced in China, and industrial application demonstration projects of direct combustion of biomass such as straws and chaffs or biomass-coal mixed combustion power generation are built, so that project feasibility research work is completed at present.

The biomass solidified forming fuel is prepared by crushing agricultural and forestry wastes such as crop straws, rice husks and wood chips, conveying the crushed wastes into a forming device, and compressing the crushed wastes into a required shape under the action of external force. Then directly burning as fuel, or further processing to form biochar. At present, the biomass curing forming machine researched and developed in China is also applied to production. The produced compact formed fuel has also been applied to heating and small boilers. The determination shows that the pollutant discharged by the fuel is lower than that of coal, and the fuel is a high-efficiency clean renewable energy source. Compared with other methods for producing the biomass energy, the solidification forming method has the characteristics of simple production process and equipment, easy operation, strong adaptability of the production equipment to various raw materials, convenient storage and transportation of the solidified and formed fuel (long-time storage and long-distance transportation), easy realization of industrial production and large-scale use and the like. In addition, the existing combustion equipment, including boilers, stoves and the like, can be used after being simply transformed. The formed fuel is convenient to use, particularly for high and cold areas in the north of China, the kang stove is a main heating form in winter, the formed fuel has traditional use habits in vast rural areas, and the formed fuel is easy to accept by common people.

Biomass is widely available and may be derived from wood, agricultural by-products, animal wastes, pulp, paper and the like, while biomass material in original form is usually rich in moisture and large in particles, which is not suitable for direct application, so drying treatment is a necessary means for improving the use efficiency.

The management of the three wastes disposal work is always the central importance of the environmental protection management work, the disposal management of the waste water, the waste gas and the waste residue is gradually changed to rationalization, standardization and scientification, and the management of the waste residue is also promoted to unprecedented level. The treatment of the excess sludge in the sewage treatment plant is a prominent problem faced by current environmental protection management work, each sewage treatment plant is faced with the problem of how to treat a large amount of excess sludge generated every day, and the treatment is a major point of work of enterprises and environmental protection departments at all levels due to the reasons of large generation amount, difficult transfer treatment, high treatment cost and the like.

At present, no proper compromise treatment method exists in China, and the sludge for treating industrial wastewater contains a certain proportion of heavy metal substances, hydrocarbons, oils and other toxic and harmful substances, belongs to the category of dangerous wastes, is randomly stacked for a long time, and various harmful substances can be enriched in soil or undergo a physical and chemical reaction, so that secondary pollution such as soil pollution hardening, underground water quality pollution and the like can be caused.

Therefore, the sludge disposal problem has become an urgent problem to be solved in most sewage treatment plants, and whether the sludge disposal is appropriate has been linked to the survival of enterprises and the development of the sewage treatment plants.

Two thirty years ago, europe will begin to adopt the "heat drying and incineration" technology to treat sludge, which mainly uses the principles of thermodynamics and hydrodynamics and effectively combines mechanical and material technologies to treat sludge, in summary, the technology is a cross fusion of multiple disciplines and technical application fields, and sludge treatment by the drying and incineration process can well achieve the treatment targets of "reduction, harmlessness and recycling". Compared with the prior art that the sludge is treated by adopting the heat drying technology relatively late in China, foreign technologies and equipment are mainly introduced at present, and the problems of various drying process types, safety, stability, energy consumption cost and the like are prominent.

The currently commonly used 7 sludge drying technologies include:

1. electric energy sludge drying method

An electric energy sludge drying method is to convert electric energy into energy in the forms of heat energy or microwaves and the like, heat wet sludge to evaporate water, and dry the sludge, and usually adopts an electric heating furnace to indirectly dry the sludge.

The sludge drying by the heat source is generally an indirect drying mode, and the requirement on a heat exchanger is higher. In recent years, the development of a hot water drying method is rapid, and a plate-and-frame filter pressing-hot water vacuum drying technology developed in Germany is a typical representative of the hot water drying technology.

The advantages and disadvantages are as follows: the equipment is simple, the stability is good, the operation is convenient, the efficiency is high, but the cost is high, the equipment investment is large, and the operating cost is high.

3. Steam drying process

The steam drying method is to utilize steam heat energy to exchange heat through a shell layer of a heat exchanger to evaporate moisture in sludge and dry the sludge. Sludge drying machines using steam as a heat source are divided into different forms such as a disc type drying machine, a paddle type drying machine, a turbine type drying machine and the like according to different structures or internal components. The steam can realize comprehensive recycling and is an ideal clean heat source. Generally, low-pressure steam of about 160 to 230 ℃ under 1.0MPa is used.

The advantages and disadvantages are as follows: the novel steam sludge drying machine has the advantages of high steam drying efficiency, large operation elasticity, easiness in control, good stability and the like, and in addition, the novel steam sludge drying machine has high efficiency, lower energy consumption and large floor area, but the mode has certain odor pollution.

The technology utilizes solar energy, and has the advantages of low-temperature drying, low operation cost, simple operation, safe and stable operation and the like by means of the traditional greenhouse drying process. The driving force is the water vapor pressure difference between the water content in the sludge and the water vapor partial pressure in the air. Considering the influences of climate, season and weather, the solar drying process is carried out in a large greenhouse provided with a sludge turning machine, wet sludge is input from one end, and dry sludge is output from the other end.

The solar drying device mainly comprises a ground structure, a greenhouse and a sludge turning machine. The ground structure is similar to a concrete road, and the sludge turning machine is arranged on the guide rails on the two sides and performs the operation of moving up and down back and forth, thereby playing the roles of spreading sludge, reversely airing and conveying sludge. Some solar greenhouse systems are also provided with a hot air blower to accelerate the evaporation of water, and some solar greenhouse systems are built more advanced.

The advantages and disadvantages are as follows: the solar drying technology has large occupied area, leads to the highest investment cost, but has the lowest operation cost, utilizes clean energy to meet the requirement of sustainable development, and has higher cost performance

5. Drying method of natural gas

The natural gas (coal gas) drying method is to use natural gas (coal gas) as a heat source for fuel and dry sludge in a drying device. In order to prevent combustion and explosion, security measures such as nitrogen protection, oxygen concentration linkage, temperature linkage, sludge back mixing and the like are generally provided so as to improve the safety of equipment operation.

The temperature of the furnace flue gas is generally between 120 ℃ and 200 ℃, huge heat energy is stored in the furnace flue gas, and the furnace flue gas is an ideal heat source for low-temperature drying of sludge. The sludge is dried by using the flue gas in two modes of directly heating and drying by using the flue gas and indirectly heating and drying. In order to ensure that the sludge can naturally form particles at low temperature, a two-stage drying process is generally adopted, wherein the water content of the sludge is reduced from about 80% to about 60% by one-stage drying, and the water content is reduced to below 40% by two-stage drying granulation, so that the 2-8 mm granular sludge is formed and convenient to recycle.
