Abstract

The utility model relates to special equipment for cremation, particularly a fuel and gas cremator with smoke upwards turned and downwards discharged, which is used for incinerating the corpses in funeral parlors. The utility model overcomes the defects that cremators with smoke downwards discharged have easy smoke seepage and cremators with smoke upwards discharged have insufficient smoke combustion. The utility model has the solving proposal for the technical problem that the fuel and gas cremator with smoke upwards turned and downwards discharged comprises a main combustion chamber, a secondary combustion chamber, a cremator door, a combustion engine and a flue. The utility model is characterized in that the main combustion chamber is positioned on the center, the secondary combustion chamber is arranged on the upper part of the main combustion chamber, and a third combustion chamber is positioned on the lower part of the main combustion chamber. The secondary combustion chamber is communicated with the third combustion chamber which is connected with an underground flue, and the smoke generated by the main combustion chamber can be upwards turned so as to enter the secondary combustion chamber on the upper part. Then, the smoke can be downwards discharged so as to enter the third combustion chamber by a connecting passage. Thus, the utility model can achieve the purposes of long stay time and sufficient combustion. The utility model is mainly used for incinerating the corpses in funeral parlors.

Description

Turn over lower-discharging type fuel oil, combustion gas dual-purpose Cremation Machine on the flue gas

One, technical field

The utility model relates to a kind of cremate special equipment, and particularly a kind of the burning on the flue gas that corpse uses for the funeral parlor turned over lower-discharging type fuel oil, combustion gas dual-purpose Cremation Machine.The abundant completing combustion of the flue gas that makes Cremation Machine produce in the process of burning the corpse, the flue gas of discharge reaches national specified discharge standard.

Two, background technology

The flue gas circulation style of the Cremation Machine that funeral and interment is at present already used mainly contains two kinds, and a kind of is the flue gas lower-discharging type: promptly the flue gas that produces from main chamber enters the secondary combustion chamber that is positioned at the main chamber below, through underground flue and smoke evacuation chimney, enters atmosphere.Another kind is row's formula on the flue gas: promptly the flue gas that produces from main chamber enters the secondary combustion chamber that is positioned at the main chamber top, enters atmosphere through aerial flue and smoke evacuation chimney.The characteristics of flue gas lower exhausting type furnace are: because the flue gas light specific gravity itself has one ascendant trend, it down to discharge, enough drafts must be arranged, when draft one timing, the time of arranging on the time ratio flue gas that flue gas stops in burner hearth is long, thereby flue gas can fully burn.But its defective is: when Cremation Machine added corpse, corpse fire burns once going into burner hearth, and dead body cart does not withdraw from as yet, and fire door can't be closed, and a large amount of flue gases has little time all row down, just goes out from stove gate, enters between cremate, has polluted working environment.The defective of flue gas upper exhausting type furnace is: because flue gas flue gas light specific gravity itself has one ascendant trend, so the row of going up of flue gas is very easy to.Can cause flue gas short at the main chamber and the secondary combustion chamber time of staying like this, be easy to generate imperfect combustion, the flue gas of discharge is black, contaminated environment.

Three, summary of the invention

The utility model technical issues that need to address are: the time of staying of prolong smoke in stove, and make interior pressure of stove and the outer balance of stove.The technical solution of the utility model is: turn over lower-discharging type fuel oil, combustion gas dual-purpose Cremation Machine on the flue gas, comprise main chamber, secondary combustion chamber, fire door, combustor, flue, it is characterized in that: main chamber is positioned at central authorities, secondary combustion chamber is on the top of main chamber, three combustion chambers are in the bottom of main chamber, two, three combustion chambers are communicated with, three times the combustion chamber is connected with underground flue, turn over the secondary combustion chamber that enters top on the flue gas that main chamber produces, arrange down by interface channel and enter the combustion chamber three times.Useful technique effect of the present utility model is: owing to set up three times the combustion chamber in the bottom of main chamber, and two, three combustion chambers are communicated with, the flue gas that makes Cremation Machine produce turns over earlier and enters secondary combustion chamber, row enters the combustion chamber three times down again, such flue gas circulation order makes flue gas increase in the time of staying of the combustion chamber of Cremation Machine, can burn fully completely, flue gas can not enter cremation workshop when fire door is not closed simultaneously, makes production environment not contaminated.Can reduce the burning time, cut down the consumption of energy.

Four, appended drawings is among the utility model structural representation figure: 1-main chamber, three combustion chambers of 2-, 3-fire door, 4-secondary combustion chamber, 5-port, 6-underground flue, 7-vertical gas pass.

Five, the specific embodiment

With reference to accompanying drawing, turn over lower-discharging type fuel oil, combustion gas dual-purpose Cremation Machine on the flue gas, comprise 1, three combustion chamber 2 of main chamber, fire door 3, secondary combustion chamber 4, port 5, underground flue 6, vertical gas pass 7.Main chamber 1 is positioned at central authorities, secondary combustion chamber 4 is on the top of main chamber 1, have three combustion chambers 2, two, three combustion chambers 2 are communicated with by two parallel vertical gas passes 7 by the rear flank portion of Cremation Machine in the bottom of main chamber 1, three times combustion chamber 2 is connected with underground flue 6.The pitted surface of main chamber 1 is flat, is convenient to operate, the circulation of deashing and flame.Each combustion chamber is furnished with a plurality of air vent (not shown), and the combustion chamber also is provided with thermocouple and pressure sensor (not shown) to show the temperature and pressure in the stove.Secondary combustion chamber 4 and main chamber 1 all are provided with port 5, and port 5 can carry out oil inflame and fuel gas buring.The circulation style of flue gas is: flue gas turns over earlier and enters secondary combustion chamber 4, solved the disadvantage that fire door 3 enters cremation workshop of easily overflowing of flue gas when adding corpse, enter combustion chamber 2 three times through 7 times rows of vertical gas pass again, at this moment resistance increases, following row's speed slows down, and such flue gas circulation order makes flue gas increase in the time of staying of the combustion chamber of Cremation Machine, can burn fully completely, enter atmosphere through spraying smoke evacuation system by chimney by underground flue 6 through three-burn flue gas.

Claims

1, turns over lower-discharging type fuel oil, combustion gas dual-purpose Cremation Machine on the flue gas, comprise main chamber, secondary combustion chamber, fire door, combustor, flue, it is characterized in that: main chamber is positioned at central authorities, secondary combustion chamber is on the top of main chamber, three combustion chambers are in the bottom of main chamber, and two, three times the combustion chamber is communicated with, and three times the combustion chamber is connected with underground flue, turn over the secondary combustion chamber that enters top on the flue gas that main chamber produces, arrange down by interface channel and enter the combustion chamber three times.
