Description

The multifunctional smokeless pressure-less boiler

The utility model relates to boiler and makes the field, in particular for the multifunctional smokeless pressure-less boiler of tourist industry for boiling water, steam and high building hot water.

Existing coal-fired steam boiler can produce steam, utilizes steam water body in the water tank of hot high building top to produce high building hot water, and this steam boiler ubiquity is seriously polluted, the cost height, and the big and body of heater pressure-bearing of energy consumption, pressure-bearing surface is big, and the shortcoming of hidden peril of explosion is arranged.Oil burning boiler has solved pollution and energy consumption problem, but but operating cost increase greatly.The patent No. is: 90217014.7 " passenger train supplies the boiling water pressure-less boiler continuously " (being commonly called as sluggard's series pressure-less boiler) overcome the shortcoming of above boiler, himself has the following disadvantages again: need after water heats in the pot body to draw up high building top water tank by heat-exchanger pump, because of the operation inconvenience, require pot body water carrying capacity big, need bigger boiler volume, cost is higher; Can not produce the pressure steam, it is poor to lack this function adaptability, and fuel used is the smokeless coal that looses, and adopts the grate firing type burning, occurs fuel easily and mixes badly with air, and burning velocity is slow, and efficient is low.

The utility model is to provide a kind of cost low, pollution-free, easy to install, safe and reliable to operation, and efficient energy-saving can be for the multifunctional smokeless pressure-less boiler of boiling water, steam and high building hot water.

The utility model is achieved in that the orderly smokeless honeycomb briquette of flue internal combustion arrangement, water body is heated the back and produces boiling water in the drum, the drum top is provided with an opening and communicates with atmosphere, boiler itself is not have to press, being attached to drum top one gas-storing pipe, gas bag pipe is communicated with through tedge, down-comer and the water-cooling wall coil pipe in flue of spiraling and forms a closed-loop path, utilize the Natural Circulation principle after the water-cooling wall heated coil, the continuous circulation of the interior water body of pipe is heated, and generation has the pressure steam to the generation air-water mixture in the gas-storing pipe after the gas bag pipe is separated in.Be provided with water one hydrothermal exchange pipe in the drum, be connected with the roof attemperater with rising, down-comer, the water body water one hydrothermal exchange pipe of flowing through absorbs water body heat in the drum in the roof attemperater, get back in the roof attemperater through the circulation rising, so continuous cycle heat exchange makes the interior water body of roof water tank be heated to form hot water.

Advantages such as it is low to the utlity model has cost, pollution-free, and efficient energy-saving is easy to operate, and is safe and reliable.

The utility model is described in further detail below in conjunction with accompanying drawing.

Accompanying drawing 1 is the utility model structural front view.

Accompanying drawing 2 is the utility model vertical views.

Accompanying drawing 3 is A-A cutaway views of Fig. 2.

Accompanying drawing 4 is B-B cutaway views of Fig. 2.

Number in the figure: 1-drum, 2-down-comer B, 3-fire door, 4-tedge A, 5-thermometric juice, 6-gas bag pipe, 7-gas-storing pipe, 8-Pressure gauge, 9-safety valve, 10-chimney, 11-ash bucket, 12-smash the slag cylindrical void, 13-down-comer A, 14-heat water valve, 15-tedge B, 16-snorkel, 17-air delivery valve, 18-roof attemperater, 19-water tank adjutage, 20-wireway, 21-drum backs down oral pore, 22-fire grate, 23-water-cooling wall coil pipe, 24-water, one hydrothermal exchange pipe, 25-flue, 26-damer of chimney.

With reference to accompanying drawing, the utility model is by boiler body, vapor system, and water one hydrothermal exchange pipe and roof attemperater are formed.In the boiler body, go up the smokeless honeycomb briquette that is burning from fire door [3] adding at fire grate [22], smokeless honeycomb briquette fully contacts because of the caloric value height and with air, energy-efficient pollution-free, ventilation is regulated by the damer of chimney [26], and the coal ash slag blanket in afterburnt is smashed to pieces from smashing slag cylindrical void [12] with steel bar, falls by ash bucket [11], the upper strata honeycomb briquette descends, and inserts new honeycomb briquette from fire door [3].After the interior water body of drum [1] is heated, produce boiling water, supply by heat water valve [14].Because of an open pore [21] that is communicated with atmosphere is arranged at the drum top, so boiler is not have to press.By gas-storing pipe [7], gas bag pipe [6], wireway [20], tedge A[4], down-comer A[13] be connected to form the vapor system of a closure at the water-cooling wall coil pipe [23] of flue [25] inwall with spiraling, the interior fired coal combustion of flue [25] produces heat is heated water-cooling wall coil pipe [23], water body rises by tedge A[4 in the pipe] enter gas bag pipe [6], water body is through down-comer A[13 in the gas bag pipe] inflow water-cooling wall coil pipe [23], so continuous circulation is heated, produce air-water mixture, after gas bag pipe [6] separates, steam enters gas-storing pipe [7] by wireway [20], water body flows into down-comer A[13 by gas bag pipe [6]], continue to participate in circulation and be heated, the air-water mixture temperature constantly increases, and steam is on the increase, after reaching certain air pressure, sent the pressure steam through snorkel [16].Because of whole vapor system is not communicated with boiler body, steam, air-water mixture all at the osculum of closure through managing interior circulation, and be provided with Pressure gauge [8], safety valve [9] moves fool proof.By roof attemperater [18], down-comer B[2], tedge B[15] communicate with the water one hydrothermal exchange pipe [24] that is immersed in drum [1] water body, form the roof hot-water supply system, the interior water body of roof attemperater [18] is by down-comer B[2] flow in water-hydrothermal exchange pipe [24], rise after absorbing the interior water body heat of drum [1], by tedge B[15] importing roof attemperater [18], so continuous circulation, the interior water body of roof attemperater [18] constantly is heated generation hot water, is emitted by adjutage [19].
