Description

The primary-auxiliary type normal-pressure boiler

The utility model relates to a kind of boiler, especially a kind of efficient, energy-conservation normal-pressure boiler.

Shortcomings such as at present, traditional normal-pressure boiler main exists that burning is insufficient, furnace temperature is low, easily breaks out boiling, low, the easy scaling of the thermal efficiency, and energy waste is big.

The purpose of this utility model provides a kind of sufficient combustion, thermal efficiency height, primary-auxiliary type normal-pressure boiler that energy waste is few.

The purpose of this utility model is achieved in that

The utility model comprises heat exchanger, water storage box, water tank, pipeline, valve, expanding chamber, the thermal insulation fire-resistant material, a dedusting box, heat-insulation layer, water storage box, it is characterized in that heat exchanger is constant slope through expanding chamber by several heat exchanging water pipes, heat exchanging water pipe's two ends and wall of inner container join, communicate with inner bag, heat exchanger and water storage box are separately by last, the ring flange of following circulating line, be fastenedly connected with screw, expanding chamber, water storage box, water pipeline 9,10 outsides are added with insulation material, combustion chamber 4,5, the 6th, be fixed in the metal-back by flame-proof thermal insulation material, it and water storage box are the split combinations, the burner that advances of the crater of body of heater and expanding chamber is to be connected with refractory material, and being added with heat-insulation layer, the bottom with expanding chamber below crater is equipped with mobilizable dedusting box.

Heat exchanger described in the utility model is by the capable water jacket that becomes a chimney flue type of shell, inner bag, the inclined-plane of upper and lower formation 45 degree, shell and outlet conduit at the most significant end of upper inclined surface link, and communicate with water jacket, form in the flue at inner bag, be equipped with the water pipe of crossing that laterally runs through and have miter angle, cross water pipe and communicate with water jacket, the oblique angle is consistent with upper and lower oblique angle; The least significant end and the water return pipeline at following oblique angle link, and communicate with inner water sleeve.

This real sheet is novel can to make full use of heat energy and waste heat because water tank and heat exchanger adopt left and right primary-auxiliary type structure, and the heat exchanger effectiveness height is easy to use, does not influence furnace temperature.

Below in conjunction with drawings and Examples the utility model is further described:

Fig. 1 is a structure chart of the present utility model;

Fig. 2 is an outside drawing of the present utility model.Among the figure: 1 upper furnace door, 2 lower furnace doors, 3 lime-ash doors, 4 upper combustion chamber, 5 lower combustion chamber, 6 cinder chamber are on 7, following grate, 8 craters, go out water circulation channel 9 times, 10 upper water-out circulation canals, 11 chimneys, 12,36 expanding chambers, retaining chambers 13,14 cross water pipe, 15 gland steam exhausters, 16 ball valves, 17 dust caps, 18 steam drains, 19 valves, 20 water inlet pipes, 21 cross water pipe, 22 heat-insulation layers, 23 outlet pipes, 24 water tanks, 25 thermometers, 26 and 38 link is return pipe, 27 outlet pipes, 28 water tanks, 29 shells, 30 thermometers, 31 return pipes, 32 refractory material heat-insulation layers, 33 return pipes, 34 dedusting boxes, 35 return pipes, 37 times heat exchangers, heat exchanger on 39,40 stop valves, 41 stop valves, 42 gland steam exhausters.

The utility model is achieved in that by water inlet pipe 20 and discharges water to retaining chamber 13, (at this moment, the retaining chamber is shown in an open position because of the anhydrous ball valve 16 that makes) water passed through water pipe 14, water tank 24, return pipe 28,38, enter heat exchanger 39, when the water level of water tank 24 constantly raises, the air of water tank 24 is by blast pipe 15, enter retaining chamber 13, along with water tank 24, the water level of retaining chamber 13 constantly raises, ball valve 16 rises, and valve 19 is closed, and the air of retaining chamber 13 is discharged by the exhaust outlet 17 of dust cap.The water of water tank 28 is by return pipe 33, enters and 31,35 enters water tank 28, heat exchanger 37, up to filling with water tank 28.(heating system)

Annotate; Water as water tank 28 is used for shower, and the front end of

water pipe

27,33 is equipped with stop valve 40,41, and stop valve is opened and can be passed through water pipe 21, retaining chamber 13, stop valve 40, enters down heat exchanger 37.The air of water tank 28 enters retaining chamber 13 by 27,41,42 and discharges by exhaust outlet 18.

When 24,28, water tank fill with after, begin the igniting.Close fire door 1, open fire door 2,3,, put into fire-lighter, add an amount of coal and close fire door 2 again at burner hearth 5, when the coal combustion of burner hearth 5 just often, open fire door 1, the coal of burner hearth 5 burnings is taken out a small amount of, put into burner hearth 4, as the coal of igniting.Insert an amount of coal to burner hearth 4 again.At this moment, smooth blow-on door 1, the oxygen of burner hearth 4 is provided by the fire door of freely opening 1, downwards burning.The oxygen of burner hearth 5 is provided by the fire door of freely opening 3, upwards burning.When normal the use, fire door 2 is in closed condition.The coal of burner hearth 5 is mainly derived from the clean and coal that falls down of burner hearth 4 unburneds, the expansion high temperature that produces during burner hearth 5 burnings by crater 8 and successively by expanding chamber 36, down heat exchanger 37, go up heat exchanger 39, expanding chamber 12, discharge by chimney 11.The expansion elevated temperature heat that burning produces is carried out hot and cold exchange with cold water in the interchanger by upper and lower heat exchanger the time.Water in the upper and lower interchanger 37,39 suck a large amount of heat and thermal expansion and be pressed into upper and lowerly to go out water circulating pipe 9,10 and enter water tank 28,24 rapidly.The water that enters water tank 28,24 enters upper and lower interchanger by return pipe 31,35 and replenishes the water that is extruded by interchanger, and circulation reaches the purpose that adds hot water successively.

When thermometer 25 reaches uniform temperature, to emit just and can use by outlet pipe 23, the water of retaining chamber 13 is stopped using when water temperature descends by crossing the water that water pipe 14 comes subsidiary water tank 23 to discharge.

When thermometer 30 (available temperature controller control shower, heating circulation pump) when reaching uniform temperature, just can use hot water.When stopping using, close fire door 1,3 and open fire door 2.The temperature of burner hearth 5 reduces rapidly, and the temperature of expanding chamber 36,12 descends rapidly, and interchanger 37,39 can't exchange.When fire door 1,3 is closed, stop oxygen supply, the coal of burner hearth 4,5 can't burn in a large number, is in the state of banking up a fire this moment.

Be placed with a spot of water in the dedusting box 34, when crater 8 to expanding chamber 12, during 36 release heat, a large amount of dusts of taking out of are through expanding chamber 12,36 o'clock, partly dust is fallen into because of the weight reason and is cooled after dedusting box 34 its most dusts enter heat exchanger, and reduce flow velocity and fall into and be coated with dirt box 34, because of heat exchanger burner hearth 4, the a large amount of absorption of 5 high temperature that discharge and reduced expanding chamber 12,36 temperature, also reduced the temperature of chimney 11, the gas of meeting cold contraction simultaneously enters chimney 11, and most dust that rises has lost suction and fallen into dedusting box 34 to reach the purpose of smoke abatement and dust control.
