Description
Technical field
The utility model relates to a kind of steam generator, particularly relates to a kind of steam generator that does not have the accumulation of heat water layer.
Background technology
Present domestic traditional steam generator can be divided into two types of hot fluid heated type and traditional electrical heated type steam raising plants according to the difference of heat energy.Hot fluid heated type steam raising plant mainly utilizes fuel oil, combustion gas, fire coal etc. as thermal source, produces high-temperature flue gas and comes the aqueous water in heat(ing) coil tube bank or the coiled pipe tube bank, produces saturated vapor.Tubular type heat transfer element flow resistance is big, and it is inhomogeneous to be heated easily, possibly produce thermal deviation during operation and cause booster, and there is very big potential safety hazard in the phenomenon that miniature boiler dry combustion method simultaneously also possibly cause the heating element heater infringement even burn out; The electrical heating type steam raising plant then utilizes the electric heating tube bank to produce steam as heater.
The fluid type heat steam raising plant still is that traditional electrical heated type steam raising plant all exists an identical point; In order to prevent the dry combustion method of heating tube bundle; They all are arranged in coil pipe tube bank, coiled pipe tube bank or electric heating tube bank below the liquid water layer liquid level, utilize specific heat of water to keep tube wall temperature greatly.Therefore, in the process that produces a certain amount of steam, existing a certain amount of water unconverted is steam, and so not only making has the portion of energy loss, and the time of generation steam is long.If often be interrupted the use small amount of steam, the accumulation of heat loss of water layer must not be irrespective, so the traditional water steam generator is uneconomic.
To the above-mentioned defective that traditional steam generator exists, scholars have carried out a series of improvement to it, are that the steam generator of the patent of CN1443293 [6] has been introduced a kind of heater that is made up of inside subject and outer body like patent publication No..The electrons heat coil is connected and heats aluminium body on the aluminium body and be transmitted to heat in the liquid through outer body; The combination of inside subject and outer body provides heat conduction efficiently to be used for gasifying liquid; This experiment has effectively alleviated the scale formation of water layer, but improves very little to heat-economy.
Publication number is that the patent of CN1155051 [7] discloses a kind of electrically heated flash steam generator; It is formed by rapid heater and automatic water replenishing device connection; Rapid heater sticks at electrothermal film and constitutes heating element heater on the sheet metal, and automatic water replenishing device is formed automatic valve by float, rubber cushion and valve port.This experiment has had better controlled to the water yield, adds the hot water layer but still exist, and just the thickness of water layer decreases.
Publication number is that the patent of CN2720264 [8] has been introduced a kind of many backhauls of electric heating atomizing flash steam generator, and it is provided with the atomizing cartridge heater in tank interior, connects the atomizing water inlet of current limliting atomizer on the top of atomizing cup; There is exhaust hole the lower end; This device changes water into water smoke and transfers water vapour again to, vertically arranges but its heater that adopts is a U-shaped, so just is unfavorable for heat conduction; Simultaneously because water smoke density greater than vapour density, also is worth discussion so its steam drain is located at the below.
Publication number is that the patent of CN101324330 [9] discloses a kind of novel steam generator of stablizing steam that provides.It utilizes the combination of U type pressure-equalizing pipe, heat exchanger, tedge, boiling tower, down-comer that water is converted into steam.Its innovative point is for utilizing U type pressure-equalizing pipe; Make its moisturizing system supply automatically; But U type pressure-equalizing pipe together with inside and outside water be heated simultaneously, its essence is also the same with the common steam generator, has only improved Automatic Water System; Have the accumulation of heat loss of subcooled water equally, so its thermal efficiency can not improve effectively.
Publication number is that the patent of CN2849477 [10] has been introduced a kind of energy-efficient flash steam generator.It is placed with heat radiation copper pearl in evaporation cavity, water inlet pipe stretches in the chamber, and heat generating member coats water inlet pipe in a tubular form continuously, has the water inlet tap hole that is communicated with evaporation cavity in the termination of water inlet pipe.This experiment can be to the first preheating of intaking through outside water inlet pipe, coating heat generating member, and the copper pearl has increased heat exchange area, but its still for directly to hot-water heating system, can't avoid the problem of water accumulation of heat loss equally.
The prior steam generator is in order to prevent the dry combustion method of heating tube bundle; They all are arranged in tube bank below the table of aqueous water; When utilizing steam, all need heat the water that exceeds the steam use amount like this, so the accumulation of heat of excessive water loss is very large comparatively speaking at every turn.So under the situation of frequently being interrupted little steam consumption, the loss of water layer heat-retaining capacity must not be irrespective.
Summary of the invention
The purpose of the utility model is to provide a kind of steam generator that does not have the accumulation of heat water layer; Adopt micro-water smoke heating technique; In the steam cavity, establish electric heating coil, accumulation of heat orifice plate and atomizer; Utilize atomizer that water is become tiny water smoke, avoid the dry combustion method of heating element heater, improved the energy-saving effect of steam generator.
The purpose of the utility model realizes through following technical scheme:
A kind of steam generator that does not have the accumulation of heat water layer; Include controller, temperature sensor, throttle grverning valve, atomizer, electric heating coil, accumulation of heat orifice plate, stop valve, hydraulic pump, overflow valve, filter, liquid container; The vapour generator body part that said steam generator is made up of steam cavity, electric heating coil, accumulation of heat orifice plate and atomizer; With the electric control system of forming by temperature sensor and controller and power supply, and the circulation part of the water of forming by liquid container, filter, hydraulic pump, stop valve, overflow valve and throttle grverning valve; Wherein the accumulation of heat orifice plate is arranged on the electric heating coil top, and wherein temperature sensor contacts with electric heating coil, controller and power turn-on; Its overflow valve and throttle grverning valve communicate with atomizer.
