Description

Double-layer grate back burns atmospheric pressure kiln

It is a kind ofly to can be used for heating equipments such as hotel, restaurant, office, school, private residence central heating, also can be used for bathing pool that double-layer grate back described in the utility model burns atmospheric pressure kiln.

The anti-burning stove of Xiao Shouing in the market, though through repeatedly improving, but still be stuck with old pattern.Do not reach anti-fully the burning, but positive and negative burning.Fire grate in the combustion chamber is circular water pipe, the add up coal of coal dust and fritter of coal very easily drains on the fire grate that is just burning, destructive distillation is not good to make coal dust and fritter like this, the coal seam thickness that adds two combustion chambers is difficult for grasping, the ventilation proportioning is difficult to rationally, so the also following burning that reaches of coal dust and fuel gas is just discharged with flue.Wasted a large amount of energy, made the thermal efficiency low, the energy-saving and smoke-removing dust removing effects is poor.At existing problem in the prior art, a kind of novel boiler of research and design, existing problem is very necessary in the prior art thereby overcome.

In view of existing problem in the above-mentioned prior art, the purpose of this utility model be a kind of coal of can following of research and design in the gasification destructive distillation rule in when burning, coal is fully burnt, the coal that newly adds is last, burning zone is down.Make the coal that newly adds on the ground floor fire grate, be heated earlier, by destructive distillation, the gas combustion that is produced by destructive distillation is formed coke by the coal of destructive distillation and burns at second layer fire grate.The coal that slag after the burning and part fall down is fallen on the deflector and is burnt for the third time, and last lime-ash is fallen in the pond, owing to add desulfurizing agent in the water, after the depositing dust desulfurization, waste gas is discharged from flue again.Really accomplish all anti-the burning.The utility model compact conformation, the economize on electricity noiseless of economizing on coal, safety collar is saved from damage up to standard, because fire grate, deflector and the whole water flowings of water jacket, so need not keep in repair.The kettleman is easy to operate, can be used for any heating bathing environment, is a kind of efficient.Energy-conservation, as the to pollute anti-atmospheric pressure kiln that burns of novel double-layer fire grate.

Double-layer grate back described in the utility model burns atmospheric pressure kiln; Its structure is made up of combustion chamber, flue, water tank, chimney, dedusting pond; The combustion chamber is positioned at the left side of body of heater, is made up of two-layer triangle water flowing fire grate, deflector, clear deflector lime-ash door, clear second layer fire grate lime-ash door, coal filling hole and water jacket; Flue is on the right side; Be water tank above combustion chamber and the flue, chimney passes in the middle of water tank, and superconducting pipe is housed in the water tank; Water tank is to be connected with punched bend by seamless steel pipe with water jacket; The dedusting pond is positioned at the bottom; Dedust port is positioned at the top of coal filling hole, the sidewall of flue; Delivery port is positioned at the top of water tank, and water inlet is positioned at the bottom of water jacket.Reduce on coal dust directly drops deflector from coal filling hole as far as possible the ventilation gaps that two-layer triangle water flowing fire grate described in the utility model, upper and lower layer grate the form position of staggering mutually.Water jacket described in the utility model, deflector, two-layer triangle water flowing fire grate are connected with the water system that water tank is formed; Water jacket, deflector, triangle water flowing fire grate will directly be heated.In water tank described in the utility model and the water jacket superconducting pipe is housed, the heat of being convenient to absorb is transmitted in the water, makes the water heating.Body of heater described in the utility model adds heat-insulation layer and promptly can be used for high temperature heat-conduction boiler.

The utility model provides a kind of novel double-layer grate back to burn atmospheric pressure kiln, thereby wasting energy of having overcome that existing boiler exists, disadvantages such as noise is big, contaminated environment, to market release a kind of simple and compact for structure, efficient low-consume, smoke medicining dust-removing effect burns atmospheric pressure kiln for double-layer grate back one, widely applicable well.The utility model without mechanically actuated, need not keep in repair and novel structure, economize on coal, economize on electricity, the thermal efficiency can reach more than 88%.It puts goods on the market in enormous quantities and will produce remarkable social benefit and economic benefit.

The utility model has two accompanying drawings, and wherein accompanying drawing 1: double-layer grate back burns atmospheric pressure kiln side view accompanying drawing 2: double-layer grate back burns among the atmospheric pressure kiln A-A view figure: 1, dedusting pond 2, clear dirt slag cover plate 3, clear deflector lime-ash door 4, clear second layer fire grate lime-ash door 5, coal filling hole 6, dedust port 7, water jacket 8, seamless steel pipe 9, punched bend 10, superconducting pipe 11, water tank 12, chimney 13, triangle water flowing fire grate 14, flue 15, deflector 16, water injection hole 17, delivery port 18, water level meter 19, concrete water seat

Concrete enforcement of the present utility model as shown in drawings, its structure is that ground floor fire grate in the combustion chamber, second layer fire grate, deflector, dedusting pond are up-down structure.The combustion chamber becomes left and right sides structure with flue.The top of combustion chamber and flue is a water tank, and chimney passes in the middle of water tank.The flame of combustion chamber has been walked a U font through deflector, flue downwards from fire grate, has formed pure anti-burning.After the water treatment of flue dust through deflector and pond, discharge by chimney through flue.The initiate coal in combustion chamber is added in above the spent coal seam, makes initiate coal be heated the process of the destructive distillation of gasifying.This process is a coal when being heated to 100, and coal is in drying stage; When coal is heated to Celsius 200 when spending, element and gas in the coal fold; When coal is heated to Celsius 350 when spending, coal begins to soften, bond; When coal is heated to Celsius 550 when spending, coal begins again to solidify makes the coal line of softening bonding be cleaved into fritter, becomes semicoke and coke.Coal gasification retort process that Here it is.Coal combustion after this process of process is the most prosperous, firepower is the strongest.When burned flame process double-layer grate, deflector, smoke box water jacket, the superconducting pipe of water tank is heated, and makes the water heating in the whole boiler.Heated water is sent from delivery port and is supplied with the user.The coal ash of burned mistake and slag fall into the pond through fire grate and deflector downwards, discharge from clear dirt slag cover plate.

Double-layer grate back described in the utility model burns atmospheric pressure kiln and adds heat-insulation layer, also can be applicable to high temperature heat-conduction boiler.
