The vertical type boiler with the towering pipe comprises a vertical type boiler with the towering pipe body, a vessel head is connected with a sealed tube opening at the top end of the towering pipe in a welded mode, a fire tube is evenly installed on the outer wall of the periphery of a furnace pipe and correspondingly communicated from top to bottom inside a water tank of the boiler body, a division wall is horizontally arranged in the middle of the furnace pipe in a sealed mode, at least two layers of water pipe furnace grates are respectively communicated with the water tank at two sides of the boiler body and horizontally installed in the middle of the furnace pipe below the division plate, at least three layers of water pipe furnace grates are respectively communicated with the water tank at two sides of the boiler body and horizontally arranged in the middle of the furnace pipe above the division plate, a smoke outlet is installed inside the furnace pipe below the water pipe furnace grates from the other side of the bottom portion to the outside of the boiler body, a smoke box is installed at the outer end of the smoke outlet, an induced draft fan is connected with one side of the bottom of the smoke box, a wind outlet of the inducted draft fan is connected with a chimney which is connected with a coal feeding chamber through a damping down exhaust pipe. The vertical type boiler with the towering pipe has the advantages of fully utilizing heat energy, completely avoiding smoke and dust, and reaching emission standard of the class one area.

Description

A kind of impact tube vertical boiler

Technical field:

The utility model relates to boiler, and particularly a kind of have smoke abatement and dust control, impact tube vertical boiler that can the Effective Raise thermal efficiency.

Background technology:

Existing impact tube vertical boiler is to be provided with a combustion chamber of stretching out impact tube from furnace roof in a furnace shell with water jacket, and the fire grate of combustion chamber adopts the individual layer water cooling tube, and pyrotechnics all is directly to discharge from impact tube.The shortcoming that exists is: it is not thorough to burn, and the thermal efficiency utilizes low, has not only wasted energy but also not environmental protection.

Summary of the invention:

It is thorough that the purpose of this utility model provides a kind of smoke abatement and dust control, and thermal efficiency utilization rate is high, the impact tube vertical boiler of environmental protection and energy saving.

The technical solution of the utility model is finished as follows, a kind of impact tube vertical boiler, it includes an impact tube vertical boiler, be respectively equipped with steam valve at the body of heater top, Pressure gauge and manhole, it is characterized in that: the top closure mouth of pipe at impact tube is welded with an end socket, in that up and down corresponding the connection is separately installed with uniform fire tube in the body of heater water tank on the outer circumferential walls of flue, be closed with partition wall one in the flue intermediate lateral, intermediate lateral is equipped with the two-layer water pipe furnace grate that is communicated with both sides body of heater water tank respectively in the flue below partition wall, form a coal chamber in the flue above water pipe furnace grate, outside a side direction body of heater of coal chamber, be communicated with a coal filling hole, form the combustion chamber that flame is downward in the flue below water pipe furnace grate, flue and the furnace wall corresponding in the combustion chamber are provided with a flame-observing hole, be provided with secondary combustion chamber in the flue bottom, flue intermediate lateral above partition wall is provided with at least three layers of water pipe row who is communicated with both sides body of heater water tank respectively, in the flue above water pipe row an inspection door is installed outside body of heater, outside the one side direction body of heater of bottom, a cleaning door is installed in the flue below water pipe row, from the bottom opposite side exhanst gas outlet is installed outside body of heater in the flue below water pipe row, a smoke box that is communicated with it is installed downwards on the furnace body outer wall of exhanst gas outlet outer end, be connected with an air-introduced machine in the smoke box bottom to a side, be connected with a chimney on the air outlet of air-introduced machine, between chimney and coal chamber, be connected with the blast pipe of banking up a fire.What adopted the junction of each fire tube and flue is a kind of without the straight section elbow.

The utlity model has take full advantage of heat energy, smoke abatement and dust control thoroughly, reach the advantage of 1 class area discharge standard.

Description of drawings:

Fig. 1 is structural representation of the present utility model.

The specific embodiment:

Describe embodiment in detail in conjunction with above accompanying drawing, the utility model is improvements over the prior art, be respectively equipped with steam valve 21, Pressure gauge 18, manhole 22 at the top of an impact tube vertical boiler, main improvement is on the impact tube top mouth of pipe sealing to be welded with an end socket 20, the corresponding connection be separately installed with uniform fire tube 23 up and down on the outer circumferential walls of flue 17 in body of heater water tank 19, the junction of each fire tube and flue is all adopted a kind of without the straight section elbow.Be closed with partition wall 12 one in the flue intermediate lateral, partition wall forms reversing chamber 14 with the flue first half, intermediate lateral is equipped with the two-layer water pipe furnace grate 9 that is communicated with both sides body of heater water tank respectively in the flue below partition wall, form a coal chamber 10 in the flue above water pipe furnace grate, outside a side direction body of heater of coal chamber, be communicated with a coal filling hole 11, form the combustion chamber 7 that flame is downward in the flue below water pipe furnace grate, flue and the furnace wall corresponding in the combustion chamber are provided with a flame-observing hole 8, fire grate is provided with secondary combustion chamber 6 in the flue bottom, flue intermediate lateral above partition wall is provided with three layers of water pipe row 15 who is communicated with both sides body of heater water tank respectively, in the flue above water pipe row an inspection door 16 is installed outside body of heater, in the flue below the water pipe row, from the bottom to a wing furnace is external a cleaning door 13 is installed, from the bottom opposite side exhanst gas outlet 24 is installed outside body of heater in the flue below water pipe row, a smoke box that is communicated with it 4 is installed downwards on the furnace body outer wall of exhanst gas outlet outer end, be connected with an air-introduced machine 3 in the smoke box bottom to a side, and in smoke box bottom to having a shoot door 5, be connected with a chimney 1 on the air outlet of air-introduced machine, between chimney and coal chamber, be connected with the blast pipe 2 of banking up a fire.

The utility model drops into fuel in the flue by coal filling hole and drops on the double-deck water pipe furnace grate and burn, burned flame enters the combustion chamber to the below of fire grate, fire grate air inlet by the secondary combustion chamber bottom blows into air-breathing again, high-temperature flue gas is introduced in the flue reversing chamber of partition wall top water pipe row heat convection by the bottom fire tube simultaneously, the flue gas that then will be carried out by air-introduced machine after excess temperature thermal release and dirt fall through smoke box and chimney enters atmosphere.Reach and take full advantage of heat energy, the again requirement of environmental protection.
