Abstract
The utility model relates to an energy-saving water coal slurry cyclone heating furnace which belongs to the field of furnaces. The integration is a connecting body of two big end up cylinders with cavities. The upper end opening of a combustion chamber on the upper part is closed, and a lower end opening is communicated with a fume chamber on the lower part. Besides, the communicating part is provided with a grate-shaped partition plate. The inner walls of the two chambers are both provided with refractory layers, a downward spiral groove is arranged along the surface layer of the refractory layer of the combustion chamber. The outer wall of the combustion chamber is provided with a thermometer, a fire door and a combustion hole, and a coal slurry gun is inserted into the combustion hole. The wall of the lower part of the combustion chamber is provided with an oblique decoking hole. A vertical vent pipe is arranged in the combustion chamber, a pipe opening on the upper end and an opening of the coal slurry gun form an included angle, and the pipe opening on the lower end is communicated with a blower outside the furnace. The wall of the fume chamber is provided with a furnace door and a butted opening, and the butted opening is communicated with an air channel. The lower part of the fume chamber forms a funnel shape and is erected on a supporting post, and the position of a funnel mouth is provided with a slag discharging hole. The outer wall of the funnel mouth surrounding the hole is provided with a vertical baffle plate, and a slag falling pool is arranged just below the baffle plate. The utility model ensures that the flame stroke in the furnace is formed from top to bottom and ensures the sufficient combustion of the water coal slurry. Besides, the utility model can provide enough heat energy and can be connected with various heating devices.
Description
1, technical field: energy-conservation water-coal-slurry whirlwind heating furnace of the present utility model belongs to the kiln field.
2, background technology: since at present in the coal water slurry boiler flame be not stroke from top to bottom, cause cool water mixture burning insufficient, heating-up temperature can't satisfy process requirement of equipment such as heat-conducting oil furnace, drying tower, flame-guiding kiln and dryer.
3, summary of the invention: the purpose of this utility model is to propose a kind ofly to make flame travel from top to bottom, the energy-conservation water-coal-slurry whirlwind heating furnace that the sufficient combustion heating load is big.
The purpose of this utility model is achieved in that heating furnace integral body is two up big and down small cylindrical connectors of cavity, the combustion chamber upper port sealing on top, and lower port is communicated with the smoke chamber of bottom, and connection place level is equiped with grid shape dividing plate.Combustion chamber and smoke chamber inwall are all installed flame retardant coating, have downward helical groove along the combustion liner top layer.Be equiped with thermometer, observation door and burner port at outer wall of combustion chamber, be inserted with the coal slurry rifle in the burner port.Have oblique coke cleaning hole on the lower part wall of combustion chamber, vertical ventilation duct is equipped with at the middle part, combustion chamber, and its upper end mouth of pipe bending is horizontal tube, forms angle with same plane, coal slurry muzzle place, and the outer air blast of lower end and stove is communicated with.Have fire door and docking port on the smoke chamber outer wall, docking port is communicated with the air channel.The smoke chamber bottom is infundibulate, is erected on the pillar, and the spout of funnel place has mud hole, encircles on the spout of funnel outer wall in this hole and is equiped with vertical baffle plate, is provided with slag bath under the baffle plate.Water-coal-slurry is injected in the combustion chamber by coal slurry rifle, burner port, and the water-coal-slurry of burning from top to bottom flows along the helical groove on the flame retardant coating, and the high-temperature flue gas of its generation enters equipment to be heated through smoke chamber, air channel.
Owing to adopt technique scheme, just make the furnace flame stroke from top to bottom, water-coal-slurry can fully be burnt, and both can provide enough heat energy, can connect multiple firing equipments such as heat-conducting oil furnace, drying tower, flame-guiding kiln, dryer by docking port again.
4, description of drawings: concrete structure of the present utility model is provided by following drawing and description
Fig. 1 is energy-conservation water-coal-slurry whirlwind heating furnace structure schematic diagram
5, the specific embodiment:
Legend: 1, pillar 2, baffle plate 3, smoke chamber 4, fire door 5, air blast 6, coke cleaning hole 7, ventilation duct 8, observation door 9, combustion chamber 10, flame retardant coating 11, burner port 12, thermometer 13, dividing plate 14, air channel 15, mud hole 16, slag bath falls
Embodiment: as shown in Figure 1, heating furnace integral body is two up big and down small cylindrical connectors of cavity, the combustion chamber 9 upper port sealing on top, and lower port is communicated with the smoke chamber 3 of bottom, and connection place level is equiped with the grid shape dividing plate 13 of fire grate minor.The inwall of combustion chamber 9, smoke chamber 3 is all installed flame retardant coating 10, and flame retardant coating 10 top layers of suitable combustion chamber 9 have downward helical groove.9 outer wall is equiped with thermometer 12 in the combustion chamber, has observation door 8 and burner port 11, is inserted with the coal slurry rifle in the burner port 11.Have the two oblique interior coke cleaning holes 6 of feeding chamber on 9 lower part walls of combustion chamber.9 middle parts, combustion chamber are equiped with vertical ventilation duct 7, and this pipe upper end mouth of pipe bending is horizontal tube, forms angle with same plane, coal slurry muzzle place, and the outer air blast 5 of lower end and stove is communicated with.Have fire door 4 and docking port on smoke chamber 3 walls, docking port is communicated with stove air channel 14 outward.Smoke chamber 3 bottoms are infundibulate, are erected on the vertical pillar 1, and the spout of funnel place has mud hole 15, encircle on the spout of funnel outer wall in this hole and are equiped with vertical baffle plate 2, are the slag bath 16 that falls under the baffle plate 2.
During operation, water-coal-slurry sprays into combustion chamber 9 internal combustion by the coal slurry rifle in the burner port 11, the water-coal-slurry of burning from top to bottom flows along the helical groove on the flame retardant coating 10, the high-temperature flue gas of its generation enters equipment to be heated through smoke chamber 3, air channel 14, and the residue after the burning falls into slag bath 16 by mud hole 15.
