Abstract

The utility model relates to an improvement on a cracking device, in particular to the improvement on a rear end enclosure part of the cracking device. The technical scheme is that a heating cavity with a heat inlet and a heat outlet is arranged between a cracking cavity and a rear end enclosure; the heating cavity is provided with a partition plate which can divide a cavity body; an opening which is used for enabling two cavity parts to communicate is left at one end of the partition plate; and the heat inlet and the heat outlet are arranged in different cavity bodies on the two sides of the enclosed end of the partition plate. In the utility model, a simple structure is adopted to effectively solve the problem that oil gas and solid matters generated during the cracking are cooled and condensed at the place near the rear end enclosure, so that the produced oil liquid is prevented from backflowing to the cracking cavity to influence the follow-up cracking process or influence the quality of the solid matters or the oil yield; and the normal operation of the equipment is also fully guaranteed.

Description

Cracker

Technical field

The utility model is a kind of improvement of cracker, particularly to the improvement partly of cracker rear head.

Background technology

Rubber, plastics at high temperature carry out cracking and generate oil gas and solid matter, and oil gas need further be handled by deriving laggard row in the cracking chamber.But oil gas is during near cracking chamber delivery port, because the temperature at rear head place descends, and oil gas promptly possibly liquefied in the cracking chamber, and flows into the cracking chamber and mix with solid matter once more and cause the decline of butyrous loss and solid matter quality.

Summary of the invention

The purpose of the utility model is: design a kind of cracker that oil gas is caught a cold and liquefied before discharging the cracking chamber that prevents.

The technical scheme of the utility model is between cracking chamber and the rear head heating chamber to be set.The utility model increases heating chamber herein; Purpose is the temperature around keeping, and can keep original gaseous state when making oil gas arrive here, thereby successfully by discharging in the cracking apparatus; The work that guarantees whole plant thus is smooth and easy, and guarantees the quality and the oil yield of product.

For making rear head portion distributed heat even, the dividing plate that it is divided into out cavity is set in the described heating chamber, an end of dividing plate leaves the opening that two portions cavity is communicated, and heat inlet and heating outlet are arranged in the different cavitys of dividing plate closedend both sides.Like this, get into the path flows that the thermal barrier of heating chamber can be confirmed along dividing plate, so protection as far as possible in heating chamber with the heat promulgation evenly, making all can be because of meeting cold condensation near the oil gas of its each several part.

Above-mentioned dividing plate can one aperture position interlace a plurality of.In the utility model, can adopt a dividing plate.

The oil gas output tube of some cracker is arranged on the rear head, for this kind structure, should make the oil gas output tube that joins with the cracking chamber that links to each other pass heating chamber and rear head.Its concrete structure is: dividing plate is vertically, and it is made up of the top of the tube wall that connects the oil gas output tube and two portions of bottom, and the opening between two cavitys is positioned at the heating chamber bottom, and heat inlet and heating outlet are positioned at heating chamber top and lay respectively at the dividing plate both sides.

In addition; For the solid substances that cracking is produced also remains on higher temperature; State after making it keep cracking is convenient to discharge, and is prevented possible butyrous sneaking into; Be preferably in the extraction line heating chamber that the rear side setting of the solids extraction line of cracking cavity rear end communicates with heating chamber, thus heating when realizing to solids

Oil gas and solids that the utility model adopts simple structure to solve the cracking generation are effectively met cold coagulating near rear head the time; And prevent that the fluid that produces is back to the cracking chamber; Influence follow-up cracking process; Or the quality and the oil product that influence solid matter go out rate, and fully guarantee the normal operation of equipment.

Embodiment

Embodiment 1:

Present embodiment comprises cracking chamber and rear head, and the oil gas output tube in cracking chamber is arranged on the cracker cavity of rear head front end.At the inboard setting of the rear head heating chamber that have heat inlet and heating outlet adjacent with the cracking cavity rear end.

Embodiment 2:

Present embodiment comprises cracking chamber and rear head, and the oil gas vent in cracking chamber is arranged on the cracker cavity top of rear head front end, and its solids extraction line is arranged on the below.At the inboard setting of the rear head heating chamber that have heat inlet and heating outlet adjacent with the cracking cavity rear end.In the solids extraction line outside, there is the extraction line heating chamber to communicate with heating chamber.

Embodiment 3

Present embodiment comprises cracking chamber and rear head, and the oil gas output tube in cracking chamber is passed by rear head.Between rear head and cracking chamber, be provided with heating chamber, the oil gas output tube is passed by heating chamber.Have three parallel dividing plates that cavity is divided into four parts in the heating chamber, heat inlet and heating outlet are connected with first part and last part cavity respectively.Three dividing plates all have an end to be connected with the heating chamber side face, and with this end sealing, its other end and heating chamber side face leave opening, but the aperture position of three dividing plates staggers each other.

Embodiment 4

As shown in the figure, present embodiment comprises cracking chamber 8 and the rear head that is installed on 8 rear ends, cracking chamber, is provided with heating chamber 3 in rear head 9 inboards, and the oil gas in cracking chamber 8 goes out output tube 1 and passed by the top of heating chamber 3 and rear head 9.Two portions before and after heating chamber 3 is divided into by the intravital vertical dividing plate 4 in chamber.Dividing plate 4 is made up of two portions up and down, and top is the sealing of the gap between oil gas output tube 1 and heating chamber 3 upper walls, and the bottom is by the bottom of lower surface to the heating chamber 3 of oil gas output tube 1, and leaves hot-fluid in the bottom and turn round mouth.The solids extraction line 6 that the bottom of 8 rear ends, cracking chamber is communicated with its cavity in addition has extraction line heating chamber 5 to communicate with heating chamber 3 at the rear side of solids extraction line 6.The heat inlet 2 and the heating outlet 7 of heating chamber 3 lay respectively at the top of heating chamber 3, and lay respectively at dividing plate 4 both sides.
