Combined integrated steam evaporator

Abstract

The invention discloses a combined integrated steam evaporator, and relates to the field of heat energy machines. The left side of leftmost evaporator body is provided with a water inlet pipeline leading to a barrel assembly and a feeding device of the water inlet pipeline, the right side of the rightmost evaporator body is provided with a water inlet pipeline leading to the barrel assembly and afeeding device of the water inlet pipeline, and a liquid level meter is further arranged on the side surface of each evaporator body in a matched mode; a plurality of groups of operation door bodies are arranged in front of each evaporator body from top to bottom, and water film dust removal equipment is longitudinally arranged; a pressure gauge interface, a safety valve interface and a main steamvalve are arranged on the upper surface of the barrel body assembly, and a steam recirculation pipeline is further arranged in the barrel body assembly in a matched mode; and the steam recirculationpipeline is in communication with a main steam valve port. According to the combined integrated steam evaporator, water can be heated in a circulating mode through the high-temperature flue gas, the unsaturated steam is subjected to secondary circulation multi-return-cycle heating by means of the flue gas through the steam recirculation pipeline, the temperature of the flue gas is effectively utilized, the temperature of the steam at the outlet is improved, the energy consumption is also reduced, and the cost is saved.

Description

technical field [0001] The present invention relates to a combined steam evaporator in the field of thermal energy machinery. Background technique [0002] A steam evaporator is commonly known as a boiler. It is a mechanical device that uses the heat energy of fuel or other energy sources to heat water into hot water or steam. , the boiler includes two parts: the pot and the furnace; the industrial boiler is an indispensable equipment for providing the steam required for production and heating in various industrial enterprises; the traditional steam evaporator mostly uses a combination of straight tubes, curved tubes and drum The structure is formed, the steam output time is slow, the evaporation rate cannot be increased, and the steam output temperature is low. The boiler that uses biomass energy as fuel is called a biomass boiler, and is divided into biomass steam boilers, biomass hot water boilers, Biomass hot blast stove, biomass heat-conducting oil furnace, vertical bi...

[0002] A steam evaporator is commonly known as a boiler. It is a mechanical device that uses the heat energy of fuel or other energy sources to heat water into hot water or steam. , The boiler includes two parts: the pot and the furnace; the industrial boiler is an indispensable equipment for providing the steam required for production and heating in various industrial enterprises; the traditional steam evaporator mostly uses a combination of straight tubes, curved tubes and drums The structure is formed, the steam output time is slow, the evaporation capacity cannot be increased, and the steam output temperature is low. The boiler that uses biomass energy as fuel is called a biomass boiler, and is divided into biomass steam boilers, biomass hot water boilers, Biomass hot blast stove, biomass heat-conducting oil furnace, vertical biomass boiler, horizontal biomass boiler, etc.; classification of biomass boilers: horizontal biomass boiler, vertical biomass boiler; biomass gas heat-conducting oil furnace, biomass Material steam boilers, biomass hot water boilers, and biomass heat-conducting oil furnaces; the structure of traditional hot water boilers mostly uses the primary air distribution at the bottom of the grate, which has low combustion efficiency, less flue gas return, and low utilization. The consumption is relatively high, and the desired effect cannot be achieved
