Abstract
The invention discloses an inclined gas-liquid two-stage separator for a waste plastic granulator and a separation method for the inclined gas-liquid two-stage separator. The inclined gas-liquid two-stage separator consists of a gas separator and a liquid standing separator; the liquid standing separator is separated into a standing separation chamber and an overflow chamber by an inclined separating plate; the gas separator has an inclined tubular structure; the waste gas enters a snakelike pipe air passage of the gas separator from a high-temperature mixed gas inlet at the top of the gas separator and exchanges heat with a cooling water passage of the gas separator, the cooled gas is exhausted from an exhaust port of the lower part of the gas separator, and the cooled and condensed mixed liquid enters the standing separation chamber through a diversion pipe; and after the mixed liquid is stood and demixed, the components of different specific gravity are respectively discharged through the liquid overflow ports on the side walls of the standing separation chamber and the overflow chamber or the drain outlet of the bottom of the liquid standing separator. By a simple structural mode, the effective separation of the components in the high-temperature mixed waste gas in the waste plastic granulating process is finished, and purification and separation of the gas and recycle of resources are realized.

Technical field
The present invention relates to a kind of emission-control equipment of Waste plastics prill machine, specifically a kind of italic formula gas-liquid two-stage separator of Waste plastics prill machine and separation method.
Background technology
The fast development of plastics industry, also brings waste plastic that people are unwilling to see and a series of social concerns that rubbish waste plastics causes.The application of plastic products has been deep into the every nook and cranny of society, and from industrial production to clothing, food, lodging and transportion--basic necessities of life, plastic products are ubiquitous.Thereupon, the waste material in various plastic packing article, shopping bag, plastic sheeting for farm use, woven bag, beverage bottle, plastic tub, electric appliance casing and plastics processing process etc. plastic garbage also constantly produces.To in the processing method of waste plastic, recycling is obviously best selection.In the method that waste plastic is recycled, it is conventional modes that waste or used plastics is processed into plastic grain as the raw material of plastic products through comminutor.After waste or used plastics is processed into particle, still there is good integrated materials performance, the technical requirements such as blowing, wire drawing, trombone slide, injection moulding, extrusion profile can be met, be widely used in plastic products enterprise.In plastic granulation process, the waste gas of generation is all directly discharge or deliver to the adsorption tower that adsorption solvent is housed to carry out adsorption treatment two kinds of forms usually.Plastics contain a large amount of organic principle by thermogenetic high temperature mix waste gas, can extract the available resources such as light oil, gasoline, diesel oil, pitch.Direct discharge can cause environmental pollution, delivers to adsorption tower process and not only wastes adsorption solvent, cause processing cost to raise, and also effectively cannot utilize the organic principle in discarding, cause the wasting of resources.
Summary of the invention
Technical problem to be solved by this invention is to provide italic formula gas-liquid two-stage separator and the separation method of Waste plastics prill machine, the condensation water in the waste gas produced can be isolated, realize effective utilization of resource in granulation process.
The present invention for solving the problems of the technologies described above adopted technical scheme is: the italic formula gas-liquid two-stage separator of Waste plastics prill machine, be made up of gas separator and liquid standing separation device, liquid standing separation device is arranged on the below of gas separator, a separating plate tilted is provided with in described liquid standing separation device, liquid standing separation device is divided into the standing separation room of bottom and overflow chamber's two parts on top by separating plate, standing separation room and overflow chamber are by the communication port of separating plate lower end or be communicated with communicating pipe, separating plate is provided with a connected entrance, standing separation room is communicated with by the bottom of connected entrance and mozzle device separated from the gas, the sidewall of standing separation room and overflow chamber is equipped with overflow mouth, the setting position of overflow mouth is higher than communication port or the upper edge of communicating pipe, sewage draining exit is provided with in the bottom of liquid standing separation device, gas separator is the tubular structure tilted, the top of gas separator is provided with the high-temperature gas mixture body entrance be connected with comminutor discharge duct, and the bottom of gas separator is provided with exhaust outlet, in gas separator, be provided with cooling-water duct and coiled pipe air flue, the water inlet of cooling-water duct is arranged on gas separator bottom, and delivery port is arranged on gas separator top.
Overflow mouth on the sidewall of described standing separation room is higher than the overflow mouth on overflow chamber's sidewall.
Described overflow mouth and sewage draining exit are equipped with control valve.
The gas-liquid separating method of the italic formula gas-liquid two-stage separator of Waste plastics prill machine is, what comminutor was discharged is mixed with organic principle, the waste gas of water vapour enters the coiled pipe air flue of gas separator from high-temperature gas mixture body entrance, high-temperature gas mixture body is assembled gradually in coiled pipe air flue, and carry out heat exchange with the water in cooling-water duct, heat is passed to the condensed water in cooling-water duct, thus make the organic principle in coiled pipe air flue in high-temperature gas mixture body, the coagulable constituents such as water vapour are condensed into liquid, the liquid of condensation enters in the liquid standing separation device that arranges below gas separator from the bottom of gas separator, the gas of cooling is discharged from exhaust outlet,
The mixing material condensed in gas separator enters standing separation room by mozzle, because the proportion of each composition of mixing material is different, in standing separation indoor there is layering in each composition after leaving standstill, the light oil on upper strata is gathered in top, standing separation room, more heavier composition enters overflow chamber by communication port after sinking, and the heaviest composition is then deposited in the bottom of liquid standing separation device; In liquid standing separation device, the component of isolated different specific weight is discharged respectively by the overflow mouth of correspondence or sewage draining exit, and Collection utilization.
The invention has the beneficial effects as follows: the high-temperature gas mixture body that waste or used plastics produces when granulation, by the condensation of gas separator, makes the condensable components condense in mist become liquid and separated.Isolated liquid component is stratification in liquid standing separation device, by the compartmentation of separating plate, makes the component of the different specific weight of precipitation by exporting outflow accordingly.Because gas separator is obliquely installed, and gas is entered by top, flow out from bottom, in the process that mist is assembled at gas separator, have time enough to contact with cooling water pipeline, the abundant condensation of condensable cost in mist can be made, thus effectively improve the effect of gas-liquid separation.By simple frame mode, to complete in waste plastic granulation process effective separation of a component in high temperature mix waste gas, achieve the recycling of gas cleaning, separation and resource.Compact equipment, occupies little space; Equipment maintenance cost is low, and manufacturing cost reduces relatively, thus significantly can reduce operating cost, increases economic efficiency.
