Description

Smelting furnace for hazardous waste resource regeneration

Technical Field

The utility model relates to an environmental protection danger is useless deals with technical field, specifically indicates a smelting furnace for danger resource regeneration.

Background

The industrial hazardous waste is a main source of hazardous waste and mainly comprises non-ferrous metal smelting waste containing copper and electroplating waste and the like. From the industrial source, the industrial hazardous waste mainly comes from the industries of chemical raw materials and chemical product manufacturing, non-ferrous metal smelting and calendering processing, non-metallic ore mining and selecting, non-ferrous ore mining and selecting and the like. Compared with general industrial solid wastes, the industrial hazardous wastes have the characteristics of difficult degradation, toxicity, corrosivity and the like, and can cause serious harm to the health of water, atmosphere, soil and even human bodies when being placed or discharged at will, so that the proper treatment of the industrial hazardous wastes is very important.

The smelting furnace in the current relevant industry danger waste treatment technology can carry out resourceful treatment to hazardous waste, copper-containing sludge, nickeliferous sludge and the like, but still has the shortcoming: firstly, the raw materials are unevenly distributed in the process of entering the furnace, so that furnace accretion is easily generated in the smelting process to influence production; secondly, the smoke flow is not smooth, and the smoke phenomenon at the top of the furnace is easy to occur; thirdly, the operation intensity in front of the furnace is high, the difficulty is high, slag discharging and melt discharging are not timely, and the tuyere is extremely easy to be filled; fourthly, the heat supply of the furnace hearth is insufficient, and the fusant in the furnace hearth is easy to cool and condense to reduce the volume of the furnace hearth.

SUMMERY OF THE UTILITY MODEL

Therefore, the utility model aims to solve the technical problem that overcome prior art wind turbine generator system easily receive the sea condition to influence, lead to the problem that the efficiency of construction is low to a receive the sea condition to influence for a short time, guarantee wind turbine generator system overall stability's simple and easy type platform truck bearing better device's manufacturing method in the at utmost.

For solving the technical problem, the utility model discloses a smelting furnace for danger resource regeneration, including furnace hearth, furnace body and furnace roof, the furnace hearth upper end is equipped with the slag notch, and the lower part is equipped with the fuse-element discharge port, the furnace body comprises the molten steel cover, the furnace body bilateral symmetry is equipped with the wind gap, the furnace body top is equipped with the furnace roof, the furnace roof is equipped with feeding device and flue gas passageway.

Compared with the prior art, the utility model the advantage lie in: the feeding device with the upper width, the lower width and the middle width is used for realizing the uniform distribution of materials and improving the material sealing effect, the generation of accretions is reduced, meanwhile, the smoke channel form can effectively avoid the accumulation of dust, and the circulation of the smoke on the charge surface is ensured; the larger angle of the tuyere brings heat to a hearth area better to prevent the melt from condensing, and the larger angle determines the height difference between the tail end of the tuyere and the melt, so that the tuyere can be prevented from being filled with the melt for a longer time under the condition that the melt is not discharged in time.

As an improvement, the feeding device is of a structure with a wide upper part, a wide lower part and a narrow middle part, and the uniform distribution and material sealing effects of materials can be realized.

As an improvement, a plurality of air ports are respectively arranged on two sides of the bottommost layer of the furnace body and are distributed at equal intervals.

As an improvement, the flue gas channel is formed by a steel shell and a special ramming material inside.

As a modification, the tuyere angle was 17 °.

Drawings

In order to make the content of the present invention more clearly understood, the present invention will be described in further detail with reference to the following embodiments of the present invention, in conjunction with the accompanying drawings.

Fig. 1 is a schematic view of a smelting furnace for the regeneration of hazardous waste resources.

As shown in the figure: 1. the furnace comprises a furnace cylinder, 2, a furnace body, 3, a furnace top, 4, a tuyere, 5, a melt discharge port, 6, a slag outlet, 7, a flue gas channel, 8 and a feeding device.

Detailed Description

As shown in fig. 1, the present embodiment provides a schematic structural diagram of a smelting furnace for hazardous waste resource regeneration, which can be used for treating copper-containing sludge, electroplating wastes, and the like. In particular, the smelting furnace comprises a hearth 1, a furnace body 2 and a roof 3.

The furnace hearth 1 consists of an outer steel shell and an inner refractory material, a slag discharge port 6 is arranged at the upper part of the furnace hearth 1, and a melt discharge port 5 is arranged at the lower part of the furnace hearth 1, so that melt and slag generated by reaction in the furnace body 2 can be separated in the furnace hearth 1, the slag can overflow through the slag discharge port 6 and be discharged, and the melt is discharged through the melt discharge port 5. The bottom of the furnace hearth is provided with 10 mechanical jacks, the bottom of each jack is fixed on the flat trolley, and the furnace hearth can be rapidly and safely dismounted and mounted by operating the jacks.

The furnace body 2 is composed of a steel water jacket. Wherein, be provided with a plurality of wind gap 4 in the bilateral symmetry of lower water jacket, the stove is blown into to this wind gap 4 of air accessible, and the wind gap angle is 17, and the angle is bigger than conventional smelting furnace, and great wind gap angle carries the heat to the furnace pot region better, prevents that the fuse-element from condensing, and great angle has decided the terminal difference in height with the fuse-element of wind gap simultaneously, under the untimely condition is emitted to the fuse-element, can prevent that the fuse-element from irritating the wind gap for a long time.

The feeding device 8 is made of steel plates and lining ribs, is wide at the top, wide at the bottom and narrow in the middle, can be effectively sealed while realizing uniform distribution, prevents smoke from escaping, is hung on a water jacket on the top of the furnace and can be taken out from the furnace through a travelling crane.

The flue gas channel 7 steel shell is formed by adding special ramming material inside, the inner wall is smooth, the inclination angle is 60 degrees, the requirements of high temperature resistance and heat preservation are met, meanwhile, the deposition of particles in the flue gas is effectively reduced, and the normal circulation of the flue gas is ensured.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. This need not be, nor should it be exhaustive of all embodiments.
