The utility model relates to a boiler, concrete one kind is as hazardous waste innocent treatment's boiler concurrently, including the furnace body, be close to set up one end confined high temperature resistant tubular metal resonator in the furnace at furnace body top, the open end of tubular metal resonator is sealed to be worn out bend upwards connect one behind the lateral wall of furnace body and hold the hopper of dress tar form residue, be located furnace a plurality of overflow mouths are seted up to the below of tubular metal resonator, correspond every the position of overflow mouth spiral helicine pole that prolongs of welding on the tubular metal resonator. Compared with the prior art, the utility model discloses utilize current industry or life boiler to realize the tarry residue innocent treatment to non ferrous metal pyrometallurgy in-process production to retrieve and burn the waste heat and be used for comprehensive utilization and materialization processing and worker's bathing, life etc. reduce the waste of treatment cost and energy.

Description

Boiler capable of performing harmless treatment on hazardous wastes

Technical Field

The utility model relates to a boiler, concretely a boiler that is hazardous waste innocent treatment concurrently.

Background

The tar-like residue generated in the pyrometallurgical process of the nonferrous metals has high toxicity, is listed as dangerous waste according to the definition of national hazardous waste records, and needs to be subjected to harmless treatment when the waste code 321-001-11 is used. However, the amount of waste is not very large, and the waste is not available every day, and the waste is only cleaned during equipment maintenance, so that the cost is too high if a special incinerator is used for harmless treatment.

Workers are equipped with gas or coal boilers in bathing and life, the tar-like residue has a high calorific value, but cannot be directly used as the fuel of the boilers, because the tar-like residue has certain fluidity and higher fluidity in the combustion process, the tar-like residue flows out of the furnace bottom after being added into a hearth and is not completely combusted, and unburned parts and released smoke can pollute the environment.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the not enough of prior art, disclosing a boiler that is dangerous waste innocent treatment concurrently, not only can handle the tarry residue that produces at any time in the non ferrous metal pyrometallurgy process, need not special burning furnace that burns moreover, only need to add slightly to current industry or domestic boiler reform transform can. The adopted technical scheme is as follows:

the utility model provides a boiler that double as hazardous waste innocent treatment, includes the furnace body, its characterized in that: a high-temperature resistant metal pipe with one closed end is arranged in a hearth close to the top of the furnace body, the open end of the metal pipe penetrates through the side wall of the furnace body in a sealing mode and then is connected with a hopper for containing tar-like residues in an upward bending mode, a plurality of overflow ports are formed in the position, located in the hearth, below the metal pipe, of the hearth, and a spiral flow extending rod is welded on the metal pipe corresponding to each overflow port.

Further, the aperture of the overflow port is gradually reduced from the closed end to the open end. Which facilitates a substantially uniform velocity of the liquid tarry residue stream.

Furthermore, the flow extending rod is a conical thread, the outer diameter of the upper end of the flow extending rod is large, and the outer diameter of the lower end of the flow extending rod is small. The tar-like residue starts to burn at the beginning, the fluidity is larger, the outer diameter of the upper end is larger, the flow speed can be reduced, the solidification degree is higher and higher along with the burning, the fluidity of the tar-like residue is slowly reduced, the outer diameter of the lower end is small, the increase of the descending speed is facilitated, and the residue after burning is prevented from being deposited on the flow extension rod.

Furthermore, an annular groove body is arranged close to the upper end of the hopper, water is contained in the annular groove body, and the lower edge of the hopper cover is submerged in the water in the annular groove body. The heated vapor of the tar-like residue does not escape.

Furthermore, a slag groove is arranged below the furnace body, water is contained in the slag groove, the lower end of the furnace body, corresponding to the furnace bottom, extends downwards to form a sealing ring, and the lower edge of the sealing ring is immersed in the water in the slag groove. The burned residues can fall into water, and meanwhile, toxic gas cannot escape.

Compared with the prior art, the utility model discloses utilize current industry or life boiler to realize the tarry residue innocent treatment to non ferrous metal pyrometallurgy in-process production to retrieve and burn the waste heat and be used for comprehensive utilization and materialization processing and worker's bathing, life etc. reduce the waste of treatment cost and energy.

Detailed Description

The boiler which can be used for harmless treatment of hazardous wastes as shown in fig. 1-3 comprises a boiler body 1, a high-temperature resistant metal pipe 2 with one closed end is arranged in a hearth close to the top of the boiler body 1, the open end of the metal pipe 2 penetrates through the side wall of the boiler body 1 in a sealing manner and then is bent upwards to be connected with a hopper 3 for containing tar-like residues, a plurality of overflow ports 5 are formed below the metal pipe 2 in the hearth, and a spiral extending rod 4 is welded on the metal pipe 2 corresponding to each overflow port 5. The aperture of the overflow port 5 is gradually reduced from the closed end to the open end. The flow delay rod 4 is a conical thread, and the outer diameter of the upper end is large, and the outer diameter of the lower end is small. An annular groove body 6 is arranged close to the upper end of the hopper 3, water is contained in the annular groove body 6, and the lower edge of the hopper cover 7 is submerged into the water in the annular groove body 6. A slag groove 9 is arranged below the furnace body 1, water is contained in the slag groove 9, a sealing ring 10 is formed by extending the lower end of the furnace body 1 downwards corresponding to the furnace bottom 8, and the lower edge of the sealing ring 10 is submerged in the water in the slag groove 9.
