Description

The rotary plastic waste of flange-cooled many heat pipes cone, waste rubber oil refining still

One, technical field

The utility model belongs to the utilization of waste material technical field, is specifically related to the rotary plastic waste of a kind of flange-cooled many heat pipes cone, waste rubber oil refining still.

Two, background technology

Along with the widespread use at people's life and production field of plastics and rubber item, plastic waste and rubber item also increase year by year.For a long time owing to can not get effective processing, and become public hazards, i.e. contaminate environment and taking up space, useful component does not wherein obtain utilizing yet, and has caused the waste of resource.Based on the problems referred to above, in recent years, people have developed the equipment of several treatment of waste plastics, waste rubber, at present more advanced is that " the rotary plastic waste of many heat pipes cone, waste rubber oil refining still " application number is 200920014734.X, this oil refining still comprises the cone kettle, the forward and backward opening for feed and the slag-drip opening of being equipped with respectively of kettle is equipped with many heat extractions pipe vertically in kettle, the outside opening of still wall is passed in the outer end of heat pipe.Owing to supported by many heat extractions pipe in this kettle, and guaranteed on the same cross section of kettle many heat pipes are arranged, making high-temperature flue gas can be the still internal heating by heat pipe morely, suitable increase heating-surface area, also reduced certain calorific loss.But in use, because inner wall of kettle and heat pipe surface are comparatively level and smooth, difficulty forms large-area the contact with them during the raw material upset, and heating-surface area is subjected to great restriction, has reduced heating efficiency, has also caused bigger calorific loss.

Three, summary of the invention

The purpose of this utility model provides a kind of raising heating-surface area that can be bigger, reduces calorific loss, improves the rotary plastic waste of flange-cooled many heat pipes cone, the waste rubber oil refining still of heating efficiency.

For achieving the above object, the technical solution adopted in the utility model is: the forward and backward cone-shaped kettle that has opening for feed and slag-drip opening of this utility model, many heat extractions pipe is installed in kettle vertically, the outside opening of still wall is passed in the outer end of heat pipe, is characterized in: on inner wall of kettle and heat pipe radiator element is installed.

Essence of the present utility model is on inner wall of kettle and heat pipe radiator element to be installed, compared with prior art has following advantage: when 1, material such as plastic waste, waste rubber overturns in still, can form large-area the contact with inner wall of kettle and heat pipe, greatly increased heating-surface area, improve equipment heat-transfer effect and heating efficiency, reduced calorific loss; 2, make the intensity of kettle obtain further raising, prolonged work-ing life, the still wall can adopt thin structure simultaneously, has improved heat transfer efficiency, has reduced the input of cost; 3, strengthen material and in still, stirred frequency, increased the touch opportunity of gas phase behind catalyzer and the material gasification, improved the catalytic effect of catalyzer, accelerated reaction process, improved quality product.

Four, description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A sectional view of Fig. 1;

Fig. 3 is a working state figure of the present utility model.

Five, embodiment

As shown in Figure 1 and Figure 2, this practical cone-shaped kettle 11, forward and backward opening for feed 15 and slag-drip opening 16 of being equipped with respectively of kettle 11 of comprising.In kettle 11, be provided with axial centre pipe 13, on pipe core 13, vertically many row's supports are installed respectively.Every row's support by 8 radially, the heat pipe 12 that is connected on pipe core 13 and kettle 11 inwalls of interior outer end constitutes.These 8 heat pipes and are the M shape support structure in kettle inside at grade, make structure more firm.The outside opening of still wall is passed in the outer end of heat pipe 12.On the outside of the inwall of kettle 11 and heat pipe 12, be welded with some radiator element 14.Radiator element 14 is a curved-surface structure, and straight plate structure is compared, and the contact area of the maximized increase inwall of energy and heat pipe 12 and material improves heating efficiency.

As shown in Figure 3, working process of the present utility model is as follows: plastic waste, waste rubber be (plastic waste is removed impurity moisture, and waste rubber is removed steel wire, pulverizing) after pre-treatment, puts into hopper 2, is sent in the kettle 11 by hydraulic push rod 1.Kettle 11 rotates on forward and backward carrying roller 9,3 under drive-motor drives, and by 10 heating of indirect heating stove.Plastic waste, waste rubber are gasificated into C under 400 ℃ of temperature under catalyst action ₁-C ₁₈Gas, this gas is removed dust through filter 4, after water cooler 5 coolings, flow to oil-gas separator 6 certainly again.C wherein ₆-C ₁₈Liquid distillate flows out C as liquid fuel oil through liquid exit 8 ₁-C ₅After gas fraction is derived by pneumatic outlet 7, as process furnace fuel.
