Abstract
The invention relates to a recovering and recycling method for a waste paint bucket. The recovering and recycling method includes the following steps that firstly, the waste paint bucket is broken, and waste gas is collected; secondly, iron sheets and residues are baked, waste gas is collected, and the iron sheets and the residues are separated; thirdly, the collected waste gas is decomposed into water and dioxide; fourthly, a small amount of ash carried in the waste gas is purified in an electrostatic mode. According to the recovering and recycling method for the waste paint bucket, the iron sheets and the residues are generated by breaking the waste paint bucket, the waste gas generated by baking the iron sheets and the residues and the waste gas generated by breaking the waste paint bucket are collected and sent into a heat storage type incinerating system to be fully combusted, so that the waste gas is decomposed into water and dioxide, the small amount of ash in the waste gas is discharged in a concentrated mode after electrostatic purifying dust removing and filtering bag type dust removing are conducted, toxic substances in the waste paint bucket are effectively prevented from polluting the environment, effective components in the waste paint bucket are recycled, and energy is saved.
Description
Technical field
The present invention relates to the method for a kind of waste oil paint can recycling recycling, belong to waste oil paint can recovery technology field.
Background technology
Used waste oil paint can is collected, prevents it from entering the ecosystem, to a kind of behavior that environment works the mischief.Containing a large amount of noxious materials in waste and old waste oil paint can.If arbitrarily abandoned, corrupt waste oil paint can destroy our water source, and corrode crops and soil that we depend on for existence, our living environment will be faced with huge threat.So we are necessary the waste and old waste oil paint can after using to carry out recycling, one can preventing pollution environment, and two can recycle wherein useful composition, economize on resources.
Summary of the invention
For above-mentioned defect, the object of the present invention is to provide a kind of can to use after waste and old paint kettle carry out recycling, prevent its contaminated environment, wherein useful component is recycled, the method for a kind of waste oil paint can recycling recycling of economize energy.
The technical solution adopted in the present invention is for this reason:
Comprise the following steps:
(1) broken: useless bucket sends into shear crusher by conveyer belt, useless bucket is from top charging, and from bottom discharging after fragmentation, the iron plate obtained is of a size of 40mm-200mm; The waste gas produced in shattering process is collected feeding heat accumulating type incineration system by localized ducting and is focused on;
(2) thermal cleaning: the iron plate in step (1) is sent in the burner hearth of hot clean stove, the high-temperature gas of heat accumulating type incineration system is introduced in burner hearth through heat exchanger, high-temperature baking is carried out to iron sheet and residue, baking reaches uniform temperature, volatilizable composition in residue is all gasified, waste gas is sent into heat accumulating type incineration system and is focused on, and is separated by lime-ash after the baking cycle of setting by bobbing machine with scrap iron skin;
(3) waste gas harmless treatment: the organic exhaust gas that step (1) and step (2) are collected is sent into heat accumulating type incineration system in the lump, through 900-1100 DEG C of Thorough combustion, makes waste gas be decomposed into water and carbon dioxide;
(4) electrostatic depuration dedusting: carry a small amount of lime-ash secretly in the waste gas in step (3), discharge is concentrated after electrostatic precipitation system and Filter-bag Dust-removal System process, burned waste gas process can produce a large amount of heat energy, again utilizes in the hot clean stove of unnecessary heat importing through heat exchanger.
Advantage of the present invention is:
Waste oil paint can is carried out fragmentation and produces iron sheet and residue by the present invention, the waste gas when waste gas produce baking iron sheet and residue and broken waste oil paint can carries out collection feeding heat accumulating type incineration system and carries out Thorough combustion, waste gas is made to be decomposed into water and carbon dioxide, a small amount of lime-ash in waste gas, discharge is concentrated after electrostatic depuration dedusting and filter bag type dust removal process, effectively prevent the noxious material contaminated environment in waste oil paint can, wherein useful component is recycled, has saved the energy.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail, but not as foundation the present invention being done to any restriction.
A method for waste oil paint can recycling recycling, comprises the following steps:
(1) broken: useless bucket sends into shear crusher by conveyer belt, useless bucket is from top charging, and from bottom discharging after fragmentation, the iron plate obtained is of a size of 40mm-200mm; The waste gas produced in shattering process is collected feeding heat accumulating type incineration system by localized ducting and is focused on;
(2) thermal cleaning: the iron plate in step (1) is sent in the burner hearth of hot clean stove, the high-temperature gas of heat accumulating type incineration system is introduced in burner hearth through heat exchanger, high-temperature baking is carried out to iron sheet and residue, baking reaches uniform temperature, volatilizable composition in residue is all gasified, waste gas is sent into heat accumulating type incineration system and is focused on, and is separated by lime-ash after the baking cycle of setting by bobbing machine with scrap iron skin;
(3) waste gas harmless treatment: the organic exhaust gas that step (1) and step (2) are collected is sent into heat accumulating type incineration system in the lump, through 900-1100 DEG C of Thorough combustion, makes waste gas be decomposed into water and carbon dioxide;
(4) electrostatic depuration dedusting: carry a small amount of lime-ash secretly in the waste gas in step (3), discharge is concentrated after electrostatic precipitation system and Filter-bag Dust-removal System process, burned waste gas process can produce a large amount of heat energy, again utilizes in the hot clean stove of unnecessary heat importing through heat exchanger.
Further, described heat accumulating type incineration system is made up of some RTO incinerators.
Embodiment 1
The description of the process of waste oil paint can recycling recycling is as follows:
(1) broken: useless bucket sends into shear crusher by conveyer belt, useless bucket is from top charging, from bottom discharging after fragmentation, whole shattering process is that serialization is full-automatic, the iron sheet obtained is of a size of 40mm-200mm, and the waste gas produced in shattering process is collected feeding heat accumulating type incineration system by localized ducting and focused on.
(2) thermal cleaning: thermal cleaning operation is core process link, the equipment that this operation is selected is the clean furnace system of heat that two-part is made up of several hot clean stoves, its operation principle is that the organic matter in waste oil paint can is converted into gaseous state, by waste gas second-time burning in hot environment, and after the operation process such as dedusting qualified discharge.Thermal cleaning is divided into two processes, during primary combustion, iron sheet after fragmentation is sent in the burner hearth of hot clean stove by conveyer belt, the high-temperature gas of RTO incinerator is introduced in burner hearth through heat exchanger, high-temperature baking is carried out to iron sheet and residue, baking reaches uniform temperature, volatilizable composition in residue is all gasified, waste gas is sent into heat accumulating type incineration system and is focused on, by bobbing machine, lime-ash is separated with scrap iron skin after the baking cycle of setting, lime-ash is trembled into deashing funnel, scrap iron skin delivers to packing department through conveyer belt, the content of oxygen in burner hearth is accurately controlled during baking, ensure that organic matter does not have sufficient oxygen and iron plate to react and generates iron oxide while fully gasifying.
