Description
Technical Field
The invention belongs to the field of industrial steam supply, and relates to an industrial steam composite steam supply system.
Background
The high-temperature high-pressure steam is one of essential production materials in a plurality of industrial productions, and is widely applied to industries such as chemical industry, food, textile, building material manufacturing and the like. According to different pressure and temperature grades of used steam, low-pressure steam below 2MPa, medium-pressure steam between 2 and 3MPa and high-pressure steam above 4MPa are generally common, and particularly, the medium-pressure steam and the low-pressure steam are used most widely, and steam pressure of different grades has different steam supply schemes. The conventional method for using steam is to construct a small-capacity steam boiler and generate corresponding grade steam according to the self requirement, and the method is also a scheme widely adopted by a plurality of enterprises at present. However, since the self-built boiler of the user has a small capacity, the problem of pollution emission generated by the boiler cannot be solved by matching with the environment-friendly facilities which are completely built, so that the environmental pollution is large, the efficiency is low, and the reduction of carbon emission is not facilitated. Therefore, the intensive production reduces the pollution emission in the steam generation process, and the improvement of the environmental quality becomes a necessary development.
The large-scale cogeneration unit has the advantages of perfect environmental protection treatment measures and large steam generation amount, can fully exert scale benefits and reduce pollutant discharge, becomes the main scheme for replacing self-built small boilers of steam enterprises at present, and becomes the main steam source of industrial parks in various regions. At present, steam supply schemes for large-scale thermoelectric units mainly include adjustable steam extraction and non-adjustable steam extraction, and common schemes mainly include main steam extraction, cold steam extraction, hot steam extraction, medium-exhaust steam extraction and the like. At present, the most widely applied steam in the industrial steam supply market is steam with the pressure of below 3MPa, and particularly the consumption of low-pressure steam with the pressure of about 1MPa is the largest. For the grade steam, the most conventional steam supply scheme at present is that the steam is supplied to users after the temperature and pressure of hot re-steam or cold re-steam of a boiler are reduced, and the heat re-extraction is mainly used for large-flow industrial steam supply. For low-pressure steam, because the pressure and the temperature of reheated steam are higher, the phenomenon of direct temperature and pressure reduction exists greatly, the high-quality and low-use are realized, and the energy utilization efficiency is reduced. Although the steam extraction amount of the medium exhaust is large, the steam supply economy is good, and the actual operation pressure is low because the design pressure of the medium exhaust is generally between 0.5 and 1MPa, so that the user requirements are difficult to meet; for medium-pressure steam, because the number of hours of utilization of the existing thermal power generating unit is low, the existing thermal power generating unit needs to frequently participate in peak shaving, and in order to ensure steam supply pressure in low load, the existing thermal power generating unit often needs to participate in shaving and needs to greatly throttle, so that the generating efficiency of the thermal power generating unit is obviously reduced, and the cogeneration benefit is influenced.
