High-efficient steam generation system comprises oil fired boiler, water tank, water pump, inlet tube, wet return, furnace wall pipe, spiral steam channel, pipeline booster pump, steam hose, deicing executive device, air purifier, combustion chamber, high temperature smoke chamber, combustor, and the to-be-solved technical problem of the utility model is that a steam generation system who has the secondary heat exchange is provided, and the heat transfer is effectual, and compact structure can effectual improvement fuel utilization rate provides sufficient high-temperature high-speed dry-type saturated steam for the steam jet deicing car.

Description

A high-efficient steam generation system for deicing vehicle

Technical Field

The utility model relates to a steam generator field especially relates to a high-efficient steam generation system for deicing vehicle.

Background

The core device of the steam generating system is a boiler, and mechanical equipment for heating water into hot water or steam by using the heat energy of fuel or other energy sources. The boiler is generally bigger, and high temperature and high fever, and generally there is seldom vehicular boiler, especially is used in snow removing deicing field, and the boiler has fuel, gas, electric heat formula boiler, and fuel gas boiler thermal efficiency is the highest, and vertical boiler occupation space is little, is fit for on-vehicle.

The traditional vertical fuel oil steam boiler adopts a return stroke structure combining a lower hearth and an upper smoke chamber, generally, the four walls of the hearth and boiler water outside a boiler wall perform radiation heat exchange, and smoke upwards enters a smoke tube which is vertically arranged to perform convective heat exchange with the water in the tube and then flows out through the upper smoke chamber. Because the flue gas flow of the flue pipe flow is short, the flow velocity of the flue gas is slow, the heat exchange effect is poor, and simultaneously because the water capacity in the boiler is large, the fuel consumption is large when the boiler is started, and the fuel waste is serious under the condition of poor heat exchange effect. The to-be-solved technical problem of the utility model is to provide a have the secondary heat exchange, the heat transfer is effectual, and compact structure can effectual improvement fuel utilization rate's steam generation system, provides sufficient high-temperature high-speed dry-type saturated steam for the steam jet deicing vehicle.

Disclosure of Invention

The invention aims to provide an efficient steam generation system which provides sufficient, stable and efficient steam for an ice removing vehicle for removing ice by using steam.

The utility model discloses a following technical scheme realizes.

The utility model provides a high-efficient steam generation system for deicing vehicle comprises oil fired boiler, water tank, water pump, inlet tube, wet return, furnace wall pipe, spiral steam passage, pipeline booster pump, steam hose, deicing final controlling element, air purifier, combustion chamber, high temperature smoke chamber, combustor, its characterized in that: the oil burning boiler consists of a combustion chamber and a high temperature smoke chamber, wherein furnace wall pipes are densely arranged in the furnace wall of the combustion chamber, a spiral steam channel is arranged in the high temperature smoke chamber, an air purifier is arranged at a smoke exhaust port of the oil burning boiler, the spiral steam channel is communicated with a steam hose, the steam hose is provided with a pipeline booster pump, and a deicing execution device is arranged at the tail end of the steam hose.

Water turns into the spiral steam passageway behind the steam, and the spiral passageway is installed in the high temperature smoke chamber, and the wet return is used for collecting the comdenstion water and retrieves the water tank at spiral steam passageway bottom. Superheated saturated steam reaches the steam hose from an outlet at the top of the spiral steam channel, the steam in the steam hose is pressurized by the pipeline booster pump, and the steam is sprayed from the deicing execution device to melt ice and snow.

The spiral steam channel is annularly coiled in the furnace wall of the combustion chamber and is upwards coiled.

The spiral steam channel is spirally upwards arranged in the high-temperature smoke chamber, the radius of the spiral is close to that of the oil-fired boiler, the pitch of the spiral is larger than one half of the radius of the spiral, and a water guide groove is arranged on the wall of the pipeline.

And a water return pipe is arranged at the bottom of the spiral steam channel and used for recovering water left by steam-water separation in the spiral steam channel to the water tank.

Detailed Description

The technical solution of the present invention will be further explained by the following embodiments.

As shown in figure 1, the high-efficiency steam generation system for the deicing vehicle consists of an oil burning boiler 1, a water tank 2, a water pump 3, a water inlet pipe 4, a water return pipe 5, a furnace wall pipe 6, a spiral steam channel 7, a pipeline booster pump 8, a steam hose 9, a deicing actuator 10, an air purifier 11, a combustion chamber 12, a high-temperature smoke chamber 13 and a combustor 14, wherein the water pump 3 conveys water in the water tank 2 to the furnace wall pipe 6 through the water inlet pipe 4, the furnace wall pipe 6 is surrounded in the wall of the combustion chamber 12 of the oil burning boiler 1, the water in the furnace wall tube 6 is heated to boiling by high temperature heat radiation, the spiral channel 7 is installed in the high temperature smoke chamber 13, the high-temperature flue gas generated by the combustion chamber 13 scours the spiral steam channel 7 in the high-temperature flue chamber 13, the steam is heated to a higher temperature in the spiral steam channel 7 by a secondary heat exchange with the steam in the channel, and the waste smoke passes through the boiler. When steam with a certain flow velocity passes through the spiral steam channel 7, water with a little weight falls on the pipe wall due to the centrifugal force, and steam-water separation and secondary heating are simultaneously carried out. The return pipe 5 is arranged at the bottom of the spiral steam channel 7 and used for collecting condensed water to be recycled to the water tank 2. Superheated saturated steam reaches the steam hose 9 from the top outlet of the spiral steam channel 7, the steam in the steam hose 9 is pressurized by the pipeline pressurizing pump 8, and the steam is sprayed from the deicing actuator 10 to melt ice and snow.
