Description
Technical Field
The invention relates to the technical field of steam generating devices, in particular to a back-burning type normal-pressure superheated steam furnace.
Background
The steam boiler refers to an industrial boiler which heats water to certain parameters and produces superheated steam, the water is heated in a boiler barrel to be changed into steam, and the fire gives off heat in a hearth, namely the principle of the steam boiler. Steam boilers can be classified into electric steam boilers, oil steam boilers, gas steam boilers, and the like according to fuels. According to the regulation of the existing boiler safety technical supervision regulation in China, a steam boiler with the steam pressure of more than or equal to 0.1Mpa belongs to special equipment, the design, the processing, the manufacture, the installation and the use of the steam boiler are required to be supervised by a technical supervision department, and a user can only use the steam boiler after obtaining a boiler use certificate.
In industrial production, a steam boiler is a main heating device, and the production and processing of the dried beancurd sticks are no exception. The dried beancurd stick, also called beancurd sheet or beancurd sheet, is a thin film solidified on the surface of boiled soybean milk, can be eaten fresh or after being dried in the sun, has been used for over one thousand years since the Tang dynasty, is a traditional food which is very popular with Chinese people, and has the process of peeling, soaking, mixing, pulping, filtering to remove slag, boiling the pulp, peeling to extract the dried beancurd stick and drying to obtain the dried beancurd stick product. The dried beancurd stick is a high-quality bean product which is rich in nutrition and can provide balanced energy for human bodies, is widely called as 'meat in vegetable', but is balanced in energy ratio from the nutrition point of view, has higher nutrient density than that of the common bean product, is rich in nutrition, contains functional components such as VE, unsaturated fatty acid, isopropyl ketone, lecithin and the like, does not contain cholesterol, can improve cardiovascular function after being eaten frequently, supplements amino acid required by human bodies, and is a high-grade nutrient for patients with hypertension, arteriosclerosis and cardiovascular diseases. With the improvement of living standard of people, the requirements on the quality of the dried beancurd sticks are higher.
At present, there are three ways for processing bean curd sticks in scale production:
1. the traditional tunnel type fire way heating mode mainly comprises the following components in part by weight: the bean curd stick forming groove, the steam generating groove, the tunnel type flame path (built by red bricks) and the chimney. The connection mode of the structure is as follows: the tunnel type flame path is arranged at the bottommost part, the steam generating groove falls above the flame path, and the dried bean forming groove is arranged right above the steam generating groove. The bottom of the steam generating groove is directly contacted with the flame of the flame path, water in the steam generating groove is heated to generate steam, and the steam heats the bottom of the dried bean forming groove. The heating mode has the following disadvantages:
1) the front end of the tunnel type flame path is provided with a combustion chamber, the tail end of the tunnel type flame path is connected with a chimney, flame generated by combustion and high-temperature flue gas penetrate through the bottom of the whole steam generation tank under the self-absorption effect of the chimney, a long flame tunnel causes uneven heating of a dried bean forming tank, the temperature difference of the dried bean forming tank is too large, and when the temperature is too high, the bottom of the forming tank generates the phenomena of sticking and scorching; when the temperature is too low, the soybean milk becomes beancurd jelly, and a film cannot be formed, so that the yield and the quality of the dried beancurd sticks are influenced.
2) The front end of the tunnel type flame path is large in flame, high in high-temperature flue gas temperature and high in partial heating of the front end of the steam generation groove, so that deformation is easily caused, and the service life is influenced.
3) The tunnel type flue fuel is not fully combusted, emits black smoke, is directly exhausted into the atmosphere through a towering chimney by self-absorption, and causes pollution to the environment; the fuel heat conversion efficiency is low, the fuel loss is large, and the use cost is high.
2. The pressure-bearing steam heating mode mainly comprises the following structures: a pressure-bearing steam boiler, a dried bean forming groove, a steam groove and a steam pipeline. The connection mode of the structure is that high-pressure steam generated by a steam boiler is conveyed into a cavity of a steam groove through a steam pipeline to heat the bottom of the bean curd stick forming groove. The heating mode has the following disadvantages:
1) the pressure-bearing steam boiler generally adopts coal and biomass as fuels, adopts a direct combustion mode, has insufficient combustion, needs to be additionally provided with a smoke and dust removal processing device to process the discharged smoke, and particularly needs to process sulfides and the like in the coal-fired boiler. The flue gas treatment device matched with the pressure-bearing steam boiler has large investment and high operation cost.
2) The pressure-bearing steam boiler belongs to special equipment, and operators are qualified after special training and certified. The installation and use of the boiler need to be declared, audited and approved by relevant departments. During the use period, supervision and inspection are also needed.
3) Potential safety hazards are easily generated when the pressure-bearing steam boiler is used, and if the pressure-bearing steam boiler is not strictly operated according to regulations and used and equipment is not maintained in place, safety accidents are easily generated, and equipment damage and personal injury are caused.
3. The heating mode of the atmospheric steam generator mainly comprises the following components in part by weight: a normal pressure steam generator, a dried bean forming groove, a steam groove and a steam pipeline. The connection mode of the structure is that saturated steam generated by the normal-pressure steam generator is conveyed into the cavity of the steam groove through the steam pipeline to heat the bottom of the dried bean forming groove. The heating mode has the following disadvantages:
1) the normal pressure steam generator generally adopts coal burning, living beings as fuel, adopts the mode of burning of just burning, and this mode of burning is not abundant enough, need increase smoke abatement dust removal processing apparatus, handles discharged flue gas, and especially coal-fired steam generator still need handle sulphide etc.. The flue gas treatment device matched with the normal pressure steam generator has large investment and high operation cost.
2) Saturated steam generated by the atmospheric pressure steam generator enters the steam groove through the steam pipeline and is uniformly dispersed into the cavity to exchange heat with the dried beancurd stick forming groove part, after the saturated steam enters the steam groove, the steam space is enlarged, the pressure is reduced, after heat exchange is carried out, the steam temperature in the steam groove is reduced, the steam temperature in the groove is lower than the condensation temperature of the steam, condensed water is generated, the steam heat utilization efficiency is low, and the normal working temperature required by dried beancurd stick forming is difficult to meet; in order to meet the normal working temperature required by the bean curd stick forming, a large amount of saturated steam needs to be input for supplementary heating, so that the steam consumption is large, the energy consumption is high, and the production cost is high.
Investigation and research show that most bean curd sticks processing plants use a normal-pressure steam boiler to provide steam for boiling milk and heating and forming at present, because pressure-bearing (the pressure is more than or equal to 0.1 Mpa) equipment is used, potential safety hazards exist, and the pressure-bearing equipment is used by administrative permission, so that the requirements on operators are high; the normal pressure steam boiler has the advantages of small potential safety hazard, low technical requirements on design, manufacture and use, safer and more convenient use for users, and lower use and operation cost. However, the steam provided by the normal pressure steam boiler has the disadvantages of high energy consumption for boiling and heating the bean milk, low forming efficiency of the dried beancurd sticks and low yield of the high-quality dried beancurd sticks.
