Description

The energy-conservation drinking water boiler of continuous water supply

The utility model relates to the energy-conservation drinking water boiler of a kind of continuous water supply.

At present, though the drink tea stove that generally uses burning is more abundant, smoke medicining dust-removing effect is better, and its internal structure is simple, does not have the flue dust sedimentation device, is discontinuous supply boiling water, and its thermal efficiency and dust removing effects are all not good.

The purpose of this utility model be to provide a kind of can boiling water without interruption, thermal efficiency height, water supply and energy saving drinking water boiler more fully burns.

The purpose of this utility model is achieved in that the energy-conservation drinking water boiler of continuous water supply structurally mainly is made up of three parts: top is pre-thermal center, the middle part is the hot water joint, the bottom is the boiling water joint, and three joints form three independently waters, i.e. warm water territory, hot water territory and boiling water territories.In the boiling water joint, be provided with flue, horizontal water tube, trunnion, fire grate.Lower furnace portion and fire grate top are provided with the fire of being constructed by refractory material of defending and are with, improved the heat storage capacity in coal seam like this, thereby the abundant burning that helps burning, be provided with in water supply tank, filling pipe, blast pipe, fire door, the water supply tank outside the boiling water joint ball-cock assembly is housed, the water level of boiling water joint will be controlled by the ball-cock assembly in the water supply tank like this.In hot water joint, be provided with the rough dusting that dust chamber, fire tube, dust chamber are beneficial to flue gas, also increased heat exchange area simultaneously.Outer filling pipe, blast pipe, the ash door of being provided with of hot water joint.In pre-thermal center, be provided with impact tube, ash door circle and dust chamber, further improved dust removing effects so again, increased flue gas flow again simultaneously, strengthened the heat convection effect.Pre-thermal center peripheral hardware has water supply tank and ash door, and the top is provided with blast pipe, is provided with the covering of running water that ball-cock assembly is controlled pre-thermal center in the water supply tank.Pre-thermal center, hot water joint, boiling water joint are connected into as a whole by clamping ring, all each is linked into the top of pre-thermal center to the blast pipe of boiling water joint and hot water joint since the top of this section.The filling pipe of boiling water joint is to be connected on the water supply tank of boiling water joint by the top that hot water saves, and by ball-cock assembly control, is connected to the bottom of boiling water joint again by the bottom of water supply tank.The filling pipe of hot water joint is connected to the bottom of hot water joint by the top of pre-thermal center.Pre-thermal center top is equipped with water supply tank, is equipped with ball-cock assembly in the water supply tank and controls covering of running water; Water supply tank bottom filling pipe is connected to pre-thermal center bottom, and like this as long as the water level of boiling water joint descends, the control by ball-cock assembly joins the boiling water joint to hot water, warm water and running water successively, has realized the purpose of continuous water supply like this.Simultaneously,, increased heat transfer temperature difference like this, improved heat-transfer effect because moisturizing and flow of flue gas direction become adverse current.

Fire coal of the present utility model is added on the interior fire grate of boiling water joint, through reactions such as a series of destructive distillation, reduction, oxidations, be fully burned, high-temperature flue gas after the burning flows to the dust chamber of hot water joint through the trunnion of boiling water joint: then the fire tube of baffling in the superheated water joint enters the dust chamber of pre-thermal center, and baffling enters chimney by impact tube and is discharged in the air more at last.In the dust chamber of flue gas in pre-thermal center and hot water joint, because the repeatedly baffling of flue gas and sharply reducing of cigarette speed, the grit in the flue gas is deposited in the dust chamber bottom, thereby has played the smoke abatement and dust control effect under the double action of gravity and inertia.

Owing to adopt such scheme, the utility model is particularly used ball-cock assembly and is controlled the moisturizing in three waters and make it can boiling water without interruption; Because water inlet forms the temperature difference that adverse current has increased cigarette temperature and heated medium (water) with flue gas flow direction, strengthened heat-transfer effect simultaneously; The flue gas expansion chamber that is provided with in hot water joint and pre-thermal center has increased heat exchange area, has strengthened the heat exchange effect; Be provided with in boiling water joint bottom and defend the fire band, be beneficial to fuel and obtain more ignition heat, strengthened combustion, thereby improved the thermal efficiency, design thermal efficiency reaches more than 70%.Flue gas owing to the effect of inertia and gravity, has obtained the effect of smoke abatement and dust control in dust chamber, reduce smoke dust discharge concentration, and its cigarette point concentration of emission is less than 200mg/NM ³, lingemann blackness is less than 1 grade.Simultaneously, the utility model coal adaptability is strong, can be with available again anthracite of bituminous coal and moulded coal.

Below in conjunction with accompanying drawing and embodiment the utility model is further described.
