Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steam engines, in particular to a steam thermal engine capable of enhancing steam dryness. Background Art
[0002] Steam generator is a widely used heating equipment. It is a mechanical device that uses the thermal energy of fuel or other energy sources to heat water into steam. It can be used in hospitals, bathrooms, hotels, textiles, clothing, food and other industries. There are many types of steam generators on the market, mainly natural gas steam generators and electric steam generators.
[0003] Steam dryness is an important indicator for measuring steam quality. It refers to the mass percentage of dry saturated steam in each kilogram of wet steam. High steam dryness means less liquid phase loss and higher thermal energy utilization rate. It is crucial for many industrial processes that rely on steam heating, driving or chemical reactions. Therefore, ensuring the appropriate steam dryness is of great significance to maintaining the stability of the production process and can significantly improve energy utilization efficiency. In today's world where energy costs are constantly rising, by optimizing steam dryness management, enterprises can effectively reduce energy consumption, reduce operating costs and achieve green production.
[0004] At present, the steam dryness of ordinary steam generators on the market is generally between 85% and 90%, while the steam dryness of some brands of steam generators is even less than 80%. Such steam carries a serious water-carrying phenomenon, which not only causes more heat loss, but also consumes more energy to produce the same amount of steam, increasing operating costs. For this reason, we propose a steam thermal engine with enhanced steam dryness, providing a steam thermal engine with a simple structure, energy saving and environmental protection. Through optimized design, the steam dryness is improved, and at the same time, enterprises can effectively reduce energy consumption, reduce operating costs, and achieve green production.

Such a phenomenon of water-carrying in steam is serious, which not only causes more heat loss, but also consumes more energy for producing the same amount of steam, thereby increasing operating costs. In order to achieve the above purpose, the present invention provides the following technical solutions: A steam thermal engine with enhanced steam dryness, comprising a thermal engine body, the bottom of the thermal engine body is fixedly connected to a bottom support, the interior of the thermal engine body is fixedly connected to a burner, the top of the thermal engine body is fixedly connected to a main steam pipe, the back of the thermal engine body is fixedly connected to a condenser, one side of the thermal engine body is fixedly connected to a water level gauge, the bottom inner wall of the thermal engine body is fixedly connected to a lower header, the interior of the thermal engine body is fixedly connected to an upper header, and the interior of the thermal engine body is fixedly connected to a Evaporation tube, the interior of the thermal engine body is fixedly connected with a mosquito coil, the lower header is an annular cavity, the bottom of the lower header is fixedly connected with a drain pipe, the drain pipe runs through the bottom support, the upper header is an annular cavity, the traditional steam generator does not have a steam reheating device, the steam dryness is low, and steam-water separation equipment needs to be added. Through a more reasonable design layout, adding mosquito coils, the radiant heat of the furnace is used to heat the steam again, reducing the water content in the steam and increasing the steam dryness, providing a more stable heat source for production enterprises, effectively reducing energy consumption, reducing operating costs, and realizing green production.
[0006] Further preferably, the interior of the upper header is communicated with one end of the mosquito coil, the interior of the burner is fixedly connected with a steam collecting chamber, and the interior of the steam collecting chamber is communicated with the other end of the mosquito coil.
[0007] Further preferably, a pipe seat is fixedly connected to the middle of the top of the steam collecting chamber, and the other end of the pipe seat is connected to the other end of the main steam pipe.
[0008] Further preferably, a plurality of evaporation tubes are fixedly connected to a side of the lower header opposite to the upper header, and the evaporation tubes are distributed in a linear array, and the condenser is fixedly connected to the top of the bottom support.

[0010] Further preferably, the water inlet system is connected to the condenser, the water level gauge is fixedly connected to one side of the thermal engine body, and a chimney is fixedly connected to the top of the thermal engine body.

Increasing the steam dryness can effectively reduce such problems, protect the equipment from corrosion and wear, extend the service life of the equipment, and reduce downtime for maintenance.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] In the utility model, the traditional steam generator does not have a steam reheating device, the steam dryness is low, and a steam-water separation device needs to be added.

The liquid water contained in the wet steam will form a liquid film on the heat exchange surface. The thermal resistance of this liquid film is large, which will hinder the heat transfer between the steam and the heat exchange surface. After the dryness is improved, the liquid water content is reduced, the thermal resistance is reduced, and the steam can transfer heat to the heat exchange object more efficiently, thereby improving the overall heat exchange capacity.
[0013] In this utility model, liquid water in low-dryness steam may cause water accumulation and corrosion inside equipment such as pipes, valves, and heat exchangers, shortening the service life of the equipment and increasing maintenance costs. Increasing the steam dryness can effectively reduce such problems, protect equipment from corrosion and wear, extend the service life of the equipment, and reduce downtime for maintenance.
