[technical field]

The utility model relates to a kind of Non-oxygen pyrolytic device that is used for offal treatment.

[background technology]

The processing mode of general discarded object, nothing more than method of burying and incineration method, because the method for burying must be sought the soil and bury, and when the capacity of burying is saturated, must seek the soil more in addition, this will cause the environmental pollution and the wasting of resources, and when handling with incinerator, be to be warmed to the condition of high temperature gradually by normal temperature, the pernicious gas that waste combustion is produced when high temperature can be broken down into innocuous gas naturally, but when discarded object drops into burning again, temperature can reduce in the stove, at low temperature, in the high temperature alternation procedure, and produce pernicious gas, with in this gas discharging atmosphere, it is very big that human beings'health is caused harm if deal with improperly.

So, other has the dealer to develop a kind of pyrolysis installation, so-called pyrolysis is meant general discarded object is placed under the state of anaerobic, utilize the heat energy cracking to make its decomposition, become liquid, the processing method of gas or residue, so claim Non-oxygen pyrolytic again, as shown in Figure 1, this pyrolysis installation 1 includes a hot blast generator 11 of sending hot-air after outside air can being sucked and heated, one warm-air pipe 12 that is communicated with hot blast generator 11, one treatment trough 13, one is arranged at the agitator 14 in the treatment trough 13, and a heating tank 15 that is located on treatment trough 13 outside wall surface and is connected with warm-air pipe 12, and this hot blast generator 11 includes an air blast 111 that outside air can be sucked, one can be with the burner 112 of being heated through the air of air blast 111, in addition, this treatment trough 13 is provided with an exhaust pipe 132, and this exhaust pipe 132 is connected with warm-air pipe 12 in addition more simultaneously, moreover this heating tank 15 is provided with a discharge pipe 151 that is connected with the external world.

As shown in Figure 1, when this pyrolysis installation 1 uses, be earlier the discarded object of desiring to carry out pyrolysis to be lost in the treatment trough 13 by discarded object input port (figure does not show), and the agitator 14 that starts in the treatment trough 13 stirs, this moment and the start of borrowing air blast 111 with the heater 112 of hot blast generator 11, so that through heater 112 back and be warmed up to air about 850～1100 degree Celsius and can enter through warm-air pipe 12 in the heating tank 15 and and discharge by discharge pipe 151, entering hot-air in the heating tank 15 when the time comes also borrows the wall of treatment trough 13 with heat that it had and is passed in the treatment trough 13, make the rising that temperature in the treatment trough 13 can be relative, this moment, discarded object promptly began pyrolysis, in pyrolytic process, at first can produce the evaporation of steam, carry out pyrolysis afterwards, and produce pyrolysis gas (be pernicious gas produce) again, the pyrolysis gas that is produced is then discharged by exhaust pipe 132 more this moment, and be connected former with warm-air pipe 12 because of exhaust pipe 132 again, the pyrolysis gas that treatment trough 13 is discharged enters in the warm-air pipe 12, and heating and blowing by means of hot blast generator 11, and then pernicious gas contained in the pyrolysis gas can be decomposed, and be discharged outside to, and then avoided the shortcoming that pernicious gas is sought to be difficult for and can to produce in the method for generally burying and incineration soil that method has again by discharge pipe 151.
