Abstract
The utility model relates to a coal-fired hot- air furnace for heating, which comprises a vertical cylindrical furnace body. A burning room is arranged on the lower section of the furnace body and, a tubular heat exchanger is arranged on the upper section of the furnace body. The tubular heat exchanger is provided with a vertical tube and, a movable closure head is mounted over the upper portion of the tube figure pattern card. The movable closure head is provided with a stack gas outlet. The tube in the tubular heat exchanger of the utility model is arranged vertically and, the upper closure head of the heat exchanger is the movable closure head mounted over the figure pattern card of the tubular heat exchanger. After used for some time and the tube of the exchanger is massed by ash and clinker, the movable upper closure head can be easily opened and the ash and clinker can be conveniently removed via a long stem instrument which is inserted the vertically tube.
Description
The utility model relates to tubulation, end socket and the device for monitoring temperature in the heat exchanger of a kind of coal-fired hot-blast stove, particularly a kind of coal-fired hot-blast stove.
Coal-fired hot-blast stove has continuous combustion chamber and tubular heat exchanger, walks flue gas in the pipe of tubular heat exchanger, walks air between pipe.Hot-blast stove can be the heating of air stream.In the prior art, the tubulation of tubular heat exchanger is that horizontal direction is placed, and the end socket of tubular heat exchanger is fixed.This coal-fired hot-blast stove can long-pending have lime-ash in the pipe in use for some time, and lime-ash is many, and influence is used, because tubulation is that horizontal positioned and end socket are to fix, so lime-ash easy-clear not; In the prior art, coal-fired hot-blast stove has only temperature indicating device in addition, does not have device for monitoring temperature.
The purpose of this utility model is in order to overcome above-mentioned deficiency, proposes lime-ash in a kind of easy removing tubulation and has the coal-fired hot-blast stove of device for monitoring temperature.
The utility model is realized with the following method.
This coal-fired hot-blast stove has vertical type cylinder shape body of heater, the body of heater hypomere is the combustion chamber, the body of heater epimere is a tubular heat exchanger, there is burner hearth the combustion chamber, burner hearth has coal feed point, slag notch, under the burner hearth fire grate is arranged, under the fire grate cinder chamber is arranged, there is air intake vent in cinder chamber, and tubular heat exchanger has vertical tubulation, on the tubulation, there is card the lower end, lower face plate is on top, combustion chamber, communicate with the combustion chamber in the pipe of tubulation, upper face plate top is covered with movable end socket, on the movable end socket flue gas outlet is arranged, the upper side of tubular heat exchanger shell has cool air inlet, the lower end side of tubular heat exchanger has hot air outlet, at the cool air inlet place axial-flow type electric fan is arranged, and is inserted with thermocouple between the pipe of tubular heat exchanger, temperature monitor is arranged on body of heater, and the temperature switch output contact of temperature monitor is connected on the power circuit of above-mentioned axial-flow type electric calorifier.
During use, fired coal combustion in the combustion chamber, high-temperature flue gas flows through in the pipe of tubular heat exchanger, heat tubulation, allow axial fan rotate, cold air is entered between the pipe of tubular heat exchanger, and cold air is heated by tubulation, and the hot-air after the heating is discharged from hot air outlet, when being higher than a certain temperature, closing axle streaming electric fan when temperature monitor can be transferred to temperature and be lower than a certain temperature, temperature open the axial-flow type electric fan.
The tubulation of tubular heat exchanger of the present utility model is vertically laid, and the upper cover of heat exchanger is the movable end socket that covers on the upper face plate of tubular heat exchanger, when using a period of time, after the tubulation inner product of heat exchanger has lime-ash, can open movable upper cover at an easy rate, insert the lime-ash that easily the tubulation inner product is had in the vertical tubulation with stock shape instrument and remove, lime-ash can fall in the combustion chamber and take out; The utility model makes coal-fired hot-blast stove can not export the cold wind that is lower than a certain temperature because temperature monitor is arranged, and the utility model is applicable to heating of house.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is that schematic diagram cuts open in the master office of looking of coal-fired hot-blast stove;
Fig. 2 is the A-A view of Fig. 1.
Fig. 1, among Fig. 2, coal-fired hot-blast stove has vertical type cylinder shape body of heater 1, the body of heater hypomere is combustion chamber 2, the body of heater epimere is a tubular heat exchanger 3, there is burner hearth 4 combustion chamber, burner hearth has coal feed point 5, slag notch 6, fire grate 7 is arranged under the burner hearth, cinder chamber 8 is arranged under the fire grate, there is air intake vent 9 in cinder chamber, tubular heat exchanger 3 has vertical tubulation 11, on the tubulation, following two ends have card 12 respectively, 13, lower face plate 13 communicates with the combustion chamber in the pipe of tubulation on top, combustion chamber, upper face plate 12 tops are covered with movable end socket 14, on the movable end socket flue gas outlet 15 is arranged, the upper side of tubular heat exchanger shell has cool air inlet 16, and the lower end side of tubular heat exchanger has hot air outlet 17, at the cool air inlet place axial-flow type electric fan 18 is arranged, be inserted with thermocouple 19 between the pipe of tubular heat exchanger, temperature monitor 20 is arranged on body of heater, the temperature switch output contact of temperature monitor is connected on the power circuit of above-mentioned axial-flow type electric calorifier.When being higher than a certain temperature, closing axle streaming electric fan when temperature monitor can be transferred to temperature and be lower than a certain temperature, temperature open the axial-flow type electric fan.
