Background

Since the year 2001 for signing POPs international convention in 5 months, China aims at the emission concentration, the emission total amount and the pollution prevention of pollutants in funeral industryResearch in the field of therapeutics is vigorously carried out. Researches show that cremation of remains and burning of remains and sacrificial offerings in the funeral activities inevitably generate chemical, physical, biological and other multi-attribute pollutants. It is found that the pollutants mainly comprise smoke and SO generated by incineration₂、NO_xAnd toxic and harmful atmospheric pollutants such as CO, HCl, heavy metal mercury and dioxin. National mandatory emission standard GB 13801-2015 "crematory atmospheric pollutants emission standard" (notice 2015 No. 27), published 16/4/2015, was implemented beginning 1/7/2015. The method has important significance for promoting the construction of funeral ecological civilization, effectively controlling and reducing the formation of atmospheric pollutants caused by cremation of remains and burning of remains and sacrificial offerings in the funeral industry, and increasing the environment-friendly supervision and law enforcement in the funeral field.

Detailed Description

The invention is further described below with reference to the accompanying drawings and preferred embodiments.

The structure of the incinerator of the integrated flue gas treatment device is shown in figure 1. The incinerator of the integrated flue gas treatment device comprises: the device comprises a sewage discharge port 1, a sedimentation tank 2, an ash bucket 3, an incineration chamber 4, a smoke collection chamber 5, an emergency exhaust port 6, a spraying device 7, a smoke pipe 8, a dry-wet separator 9, a liquid supply pipeline 10 provided with a pump and a valve, and a smoke interface 11 connected with an external treatment device. The smoke collecting chamber 5 is positioned below the incineration chamber 4, the ash bucket 3 is positioned below the incineration chamber 4, and the sedimentation tank 2 is positioned below the ash bucket 3. The flue gas treatment device comprises a spray device 7, a liquid supply pipeline 10 provided with a pump and a valve, and a flue gas pipe 8 for communicating the spray device 7 with the sedimentation tank 2, wherein the spray device 7 is arranged in the smoke collection chamber 5.

When the sacrifice personnel use the incinerator with the integrated smoke treatment device, the sacrifice articles can be respectively put into the fixed fire grate through the plurality of incineration ports arranged on the periphery of the incineration chamber and are ignited and incinerated. The ash generated by incineration directly falls into the ash bucket 3 below the fire grate, the high-temperature smoke and dust generated by incineration can upwards flow into the smoke collection chamber 5 above the incineration chamber, temperature measuring equipment is arranged on one side of the smoke collection chamber 5, and when the temperature of the smoke collection chamber is detected to reach more than 400 ℃, the motor drives the liquid pump to convey the water in the sedimentation tank 2 to the spraying device 7 positioned in the inner space of the smoke collection chamber 5 through the pipeline 10. A plurality of high-temperature atomizing nozzles are arranged in the spraying device 7, and spraying water is sprayed into downward flowing smoke obliquely upwards after being atomized, so that the contact area of water mist and the smoke is increased, and the smoke is better cooled and humidified and filtered. A part of the spray water absorbs a large amount of smoke dust and then flows into the sedimentation tank 2 together with the smoke along a pipeline communicating the smoke collection chamber 5 and the sedimentation tank 2.

The sedimentation tank 2 is provided with a fiber ball with strong adsorption and filtration functions, so that secondary filtration of smoke and dust gas can be realized. In the invention, the dry-wet separator 9 is arranged at the upper part of the sedimentation tank 2, so that water vapor rich in the sprayed flue gas is removed, the operation pressure on a next treatment device is reduced, and the use effect is improved. Interface 11 can further be connected with the processing apparatus who burns burning furnace outside, and outside dust removal can adopt cyclone or bag collector, can set up electrostatic cleaner for further getting rid of peculiar smell and tiny granule, and electrostatic cleaner's rear can set up the air exhauster, and the flue gas finally emits into the atmosphere via the chimney.

An emergency exhaust port 6 is arranged on the smoke collection chamber 5, and a filter screen and a valve are arranged inside a pipeline of the emergency exhaust port 6. When burning furnace and internals temporarily break down, can open the valve on the emergent gas vent 6, burn the emergent gas vent of flue gas accessible 6 discharges.

The bottom of the sedimentation tank 2 is provided with a sewage discharge outlet 1 so as to discharge sediments accumulated under long-term use. When the long-term use, the water in the sedimentation tank 2 needs to be changed regularly, just can satisfy the filterable needs of removing dust, is equipped with water valve and water pump for this reason sedimentation tank 2 outside, can change running water according to service condition. The inside level gauge that is provided with of sedimentation tank for the water level of monitoring sedimentation tank ensures can satisfy needs such as cooling, spray dust removal and filtration.

It will be understood by those skilled in the art that the foregoing is only a preferred embodiment of the present invention, and is not intended to limit the invention, and that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the present invention.
