Description
The utility model relates to a kind of smoke dispersal, dust removal and desulphurization calcination baker.
In forging industry, the calcination bakers that use carry out forge piece blank reheating processing more, the problem of existing calcination baker ubiquity environmental pollution, because fired coal combustion is insufficient, make a large amount of pernicious gases such as carbon monoxide, sulfur dioxide and dust in the fire coal, along with the thick smoke emission quotas, atmosphere pollution, very harmful to natural ecological environment.And the calcination baker of existing structure, forge piece blank reheating is placed directly in fire district's calcination, stokehold temperature height, and workman's working condition is very arduous.Do not have simultaneously the reasonable use waste heat yet, use the heat energy waste in vain of imitating.
It is a kind of easy and simple to handle that the purpose of this utility model is to provide, and improves work efficiency, and energy savings adopts reasonable wind distribution, supplemental oxygen, and repeated combustion is utilized waste heat, and water washing dedust etc. make coal-fired fully burning, the smoke dispersal, dust removal and desulphurization calcination baker of pollution abatement.
The purpose of this utility model is achieved in that
A kind of smoke dispersal, dust removal and desulphurization calcination baker comprises brick body of heater, flue, blank door, discloses vent, fire grate and air blast, and it is characterized in that disclosing in the vent is the second-time burning combustion chamber, and the air inlet duct that smoke eliminator is communicated with communicates with combustion chamber; Be the coal feeding pipe road that is communicated with the oxygen supply pipe between the combustion chamber, the coal feeding pipe road is provided with into coal hopper; The air draught flue is outside equipped with the cooling water jacket, is communicated with desulfurization case, fire grate by pipeline; It below the fire grate dedusting water tank.
Wall with flues in the described body of heater screws off face and is provided with fire-returning ring, wall with flues.
Between revolving, described blank door and wall with flues be provided with insulation material.
Described coal feeding pipe road and advancing is provided with into coal and argues for the sake of arguing, advances the coal baffle plate between the coal hopper.
Describedly advance in the coal hopper to be provided with sieves.
The utility model compared with prior art has following advantage:
1. reasonable wind distribution, the pipeline hot blast distributes at burner hearth Cheng Dingjun, and reaches burning for several times by smoke eliminator and fire-returning ring, and cold and hot wind is changed to burner hearth with enough expansions, hot oxygen, burning face coal, lump coal all can once fully be burnt, no longer over-emitting black exhaust at burner hearth.
2. supplemental oxygen, carrying out air blast under three mouths in coal feeding pipe road, to replenish reasonable oxygen supply combustion-supporting, saves coal-fired.
3. desulfurization is handled, and the steam that adopts the cooling water jacket to produce enters and carries out steam desulfurization in chemical desulfurization case and the fire grate, no longer produces pernicious gas CO, SO
2
4. water washing dedust, the water tank that is provided with below fire grate can make coal ash fall into the water, and reduces dust pollution.
5. repeated combustion is provided with two layers of 16 combustion chamber, and firepower is big, and makes by fire-returning ring and to arrive flame that wall with flues the revolves height wall with flues that circled round, and quickens circulation, increases high low temperature and takes over, and reaches very fast calcination blank, and energy saving improves work efficiency.
6. utilize waste heat, the waste heat of smokejack is all utilized, the water in flue water tank and the cooling water jacket can be made drinking water, washings, with good conditionsily also can do steam bath.
7. easy and simple to handle, advance coal, air-supply, oxygen supply, desulfurization, smoke elimination, dedusting and once finish, alleviated working strength of workers, reduced the stokehold temperature, improved workman's working environment.
