Abstract

The utility model relates to a novel coal-fired machine for boiler and pit furnace, in particular to the horizontal multi-spiral feeding counter heating machinery for boiler and pit furnace. The machine comprises a shell, a chamber, transfer coal device and air supply system. The shell supports the furnace body under the boiler. Two chambers are equipped inside the shell and two coal supply bunkers communicate with two chambers through two pipes. A revolving shaft with helical impeller is equipped inside the pipe. A fan is equipped beside tuyere of the shell. The chamber is covered with vents and two chambers comprise two slant-bottom boat-shape body. Two bottom grooves communicate with two coal supply bunkers with two pipes. The utility model has good ventilating effect. Coal can be sufficient burning without any extra equipment and chemicals and prevent wasting. Coal can do self-desulphurization when burning and then solidify sulfur in salt, which is called direct generating salt method.

Description

Boiler, cellar for storing things stove many spirals of level bottom feed counter burning machine

Technical field

The utility model relates to a kind of boiler, cellar for storing things stove with novel coal burner tool, particularly a kind of boiler, cellar for storing things many spirals of stove usefulness level bottom feed counter burning machine.

Background technology

Country is in order to solve problem of environmental pollution, in the environment protection standard discharge index of Chinese large-sized boiler and solution is arranged substantially.And vertical boiler, kiln cannot install smoke elimination, dedusting, desulfurizer additional, so the environmental protection of this boiler at all can't be up to standard because the unit Coal-fired capacity is too little.Therefore government advocates oil firing or burns gas.Yet the significant cost difference of combustion fuel oil and combustion gas forces people to rise vigorously to study again and has released all intentions and is to pollute little and stove and accessory that firepower is big.Put it briefly, it is big just to burn (coal adds from the top, the combustion chamber) cigarette of having exerted oneself; Cigarette is little does not exert oneself for anti-burning the (coal adds from the top, combustion chamber, and fire burns downwards).The moulded coal fire does not increase yet, and cigarette also disappears unclean.Water-coal-slurry or small-sized coal combustion equipment cannot be used again at all, and contaminated environment is just lit a fire and also must smolder, wanted to coal gas and semi-coal gas.

Be exactly to reach discharge standard in addition, install very expensive dedusting, desulphurization plant additional in discharge end.These control emission equipment all are with the living salt method of acid, need add alkali neutralization, sulfur curable in newborn salt.This improvement method is not only invested huge, the cost height, and also technology difficulty is big, causes secondary pollution again easily.Key is that combustion force is but had no to increase.In a word, waste is surprising.

The utility model content

How unelected the purpose of this utility model be to disclose a kind of level is down burning and smoke elimination, the dedusting that can increase and decrease spiral quantity according to grate side, circle size, and can the desulfurization of coal self heavy metal, the boiler of dephosphorization, store all spendable many spirals of level of small-sized coal combustion equipment bottom feed counter burning machine such as stove.

The technical scheme of being taked is in order to achieve the above object:

The utility model is made of housing, combustion chamber, feeding system and air-supply arrangement, it is characterized in that: housing 1 boiler furnace in the supported underneath of whole boiler, 10, two of two combustion chambers are housed in housing 1 to be added coal bunker 22 and is communicated with two combustion chambers 10 by two pipelines 9; In pipeline 9, the rotating shaft 2 of band helical runner is installed; Blower fan 7 device blower fan mouth 8 places outside casing 1, combustion chamber 10 is covered with air vent 4.As shown in Figure 1, 2, 3.

Described two combustion chambers are made up of two wedged bottom ship shape bodies that the metallic plate 5 that is covered with air vent 4 constitutes, and two kerves and two add coal bunker 22, are communicated with by two pipelines 9.

Described feeding system is the rotating shaft 2 that the band helical runner is installed more than two covers at least, by driving-belt 19 two gears of A, B that are fixed on the two cover rotating shafts 2 is rotated synchronously; Be fixed on raising up on the rotating shaft 2 and dial coal sheet 21, and rotary blade there are reverse impeller 6 and forward impeller 11.

Operation principle of the present utility model and advantage are:

1, between combustion chamber and the air compartment, only be separated with the metallic plate that one deck is covered with air vent, ventilation effect is very good, has satisfied the designing requirement of anti-burning (coal adds from the below, combustion chamber) to the effect of ventilation fully.

2, feeding system is owing to adopted the rotary blade that is fixed on the rotating shaft that the branch of reverse impeller and forward impeller is arranged, and group coal sheet that raises up, just can produce and just send and the anti-function that does not become piece with coal cinder of sending, can reach the coal that is sent to the combustion chamber moves up, thereby reach coal is fully burnt, be unlikely to waste.

3, do not add any equipment and medicine,, become direct living salt method at aflame coal self-desulphurization, with sulfur curable in salt.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is elaborated.

As shown in Figure 1, 2, 3, the utility model is made of housing, combustion chamber, feeding system and air-supply arrangement, housing 1 boiler furnace in the supported underneath of whole boiler, 10, two of two combustion chambers is housed in housing 1 adds coal bunker 22 and be communicated with two combustion chambers 10 by two pipelines 9; In pipeline 9, the rotating shaft 2 of band helical runner is installed; Blower fan 7 device blower fan mouth 8 places outside casing 1, combustion chamber 10 is covered with air vent 4.

As shown in Figure 1, 2, 3, described two combustion chambers are made up of two wedged bottom ship shape bodies that the metallic plate 5 that is covered with air vent 4 constitutes, and two kerves and two add coal bunker 22, are communicated with by two pipelines 9.

As shown in Figure 1, 2, 3, described feeding system is the rotating shaft 2 that the band helical runner is installed more than two covers at least, by driving-belt 19 two gears of A, B that are fixed on the two cover rotating shafts 2 is rotated synchronously; Be fixed on raising up on the rotating shaft 2 and dial coal sheet 21, and rotary blade there are reverse impeller 6 and forward impeller 11.
