Background technology
Pyrolysis reactor and separator is generally included in current pyrolysis of coal reaction unit, separator is positioned at the afterbody of pyrolysis reactor, its operational path passes in pyrolysis reactor by bituminous coal etc., enter in separator again after pyrolysis in pyrolysis reactor and be separated, and pyrolysis gas enters in separator and inevitably lowers the temperature, cause pyrolysis oil to be vented one's spleen middle precipitation from high-temperature hot, and be bonded together with dust, cause adhesion or the blocking of separating device parts, remove extremely inconvenient; And the more important thing is, because the dust carried secretly can not effectively be removed in the separator, so the tar dirt obtained is high containing rate, processing cost increases, and utility value is low; Particularly, the pyrolytic process of some internal heat types, solid particulate disturbance in pyrolyzer is violent, high-temperature hot vent one's spleen in particle concentration larger, the problem of line clogging is more serious.
Utility model content
In order to overcome the defect existed in above-mentioned prior art, the utility model proposes a kind of catalyse pyrolysis reaction unit, which solves due to pyrolyzer and gas-particle separation device, catalyticreactor independence separately, under hot conditions, the problem such as cause the high and steady running of line clogging, tar particle concentration difficult that efficiency of dust collection is low.
Its technical solution is:
A kind of catalyse pyrolysis reaction unit, comprise pyrolysis reactor and catalytic bed, the middle hypomere of described pyrolysis reactor is bilayer structure, it comprises inner and outer tubes respectively, interior pipe is pyrolysis chamber, and the middle and lower part that the middle and upper part of described outer tube is enclosed within described interior pipe forms an annular gas collection chamber, and described annular gas collection chamber is positioned at the bottom of described catalytic bed, described interior pipe and described gas collection chamber, the top of described outer tube be provided with for Gas Flow in domination set air cavity to blast cap; The bottom of described catalytic bed is oblique is provided with outlet.
Described interior pipe is connected with charging machine, inwardly manages interior transferring raw material by described charging machine.
The annular wall of described interior pipe is provided with the through hole of several different sizes, gas enters annular gas collection chamber by described through hole.
The utility model proposes a kind of catalyse pyrolysis reaction unit, it comprises pyrolysis reactor and catalytic bed, pyrolysis reactor comprises inner and outer tubes, the middle and upper part of its outer tube is enclosed within the middle and lower part of interior pipe, defining middle hypomere is double-deck pyrolysis reactor, and the place of being nested with of outer tube and interior pipe defines an annular air collecting chamber, and interior pipe and air collecting chamber keep being communicated with, the coal gas of high temperature in interior pipe can be made to enter in air collecting chamber, several through holes can be set around interior pipe and be communicated with air collecting chamber to make it;
The outer tube top at air collecting chamber place is provided with blast cap, when the coal gas of high temperature in air collecting chamber flows through blast cap, coal gas air-flow flows around cylinder, change the flow direction of coal gas of high temperature air-flow, owing to there being the existence of blast cap, change the flow direction of coal gas by adjustment blast cap, coal gas is entered below catalyzed reaction bed, from top out, increase the contact area of coal gas and catalyzer, better reach dust removing effects.
Be provided with outlet the bottom of catalytic bed is oblique, in catalytic bed, the catalyzer of inactivation can be discharged from outlet, then catalyzer is put into from the opening for feed of the left and right sides, top of catalytic bed, both the replacing of catalyzer had been facilitated, again can in time supply, more catalyst changeout in the reaction, do not need reaction to stop changing again, raise the efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, explanation clear, complete is further done to the utility model:
Fig. 1 is the structural representation of the utility model catalyse pyrolysis reaction unit;
In figure, 1, pyrolysis reactor, 11, interior pipe, 12, outer tube, 2, catalytic bed, 3, blast cap, 4, outlet, 5, charging machine.
Embodiment
As shown in Figure 1, a kind of catalyse pyrolysis reaction unit, comprise pyrolysis reactor 1 and catalytic bed 2, the partial sector of pyrolysis reactor 1 is Double-layer sleeve-type structure, it is made up of interior pipe 11 and outer tube 12, the middle and lower part that the middle and upper part of outer tube 12 is enclosed within interior pipe 11 forms an annular gas collection chamber, interior pipe 11 is pyrolysis chamber, pyrolytic reaction is there is in carbonaceous material in interior pipe 11, the annular wall of interior pipe 11 is distributed with the through hole of several different sizes, high-temperature hot in pyrolysis chamber is vented one's spleen and to be spread laterally by through hole, finally enters annular gas collection chamber; The outer tube top at air collecting chamber place is provided with blast cap 3, and annular gas collection chamber is positioned at the bottom of catalytic bed 2, the top of outer tube 12 be provided with for Gas Flow in domination set air cavity to blast cap 3; The bottom of catalytic bed 2 is oblique is provided with outlet 4, and blast cap 3 can be cylindrical ventilator, cowl or conical cowl, is more preferably tubular cap, can, by complete for coal gas of high temperature tuning, make it enter from the bottom of catalytic bed 2.
When the high-temperature gas in annular gas collection chamber is through blast cap 3, high-temperature gas air-flow flows around cylinder, changes the flow direction of coal gas of high temperature air-flow, its coal gas of high temperature is entered below catalytic bed 2, from top out, increases the contact area of coal gas and catalyzer.
Be several beds arranged in parallel in catalytic bed 2, each beds is placed with catalyzer, the partial sector of pyrolysis reactor 1 is set to Double-layer sleeve-type structure, because pyrolysis of coal is absorption reaction, pyrolytic reaction occurs in interior pipe, make pyrolyzer maintain gas collection cavity temperature a little more than the state in interior pipe always, the coal gas of high temperature produced shifts to high-temperature zone from cold zone, this avoids the liquid phase caused due to temperature drop in pyrolysis oven as much as possible and separates out, thus overcomes the problem of the adhesion of coal dust wall built-up and efficiency of dust collection decline.
The cardinal principle using method of the utility model catalyse pyrolysis reaction unit:
With the utility model device with the use of diffuser similarly to the prior art, only briefly introduce at this, composition graphs 1, nitrogen 1 is successively after filter, ball valve, flow director, control to enter charging machine 5 by check valve, and charging machine is connected with interior pipe, internal pipe feeds intake;
Secondly, keep pyrolysis oven in its heating mode, interior pipe is made to remain in certain temperature range, coal dust generation pyrolytic reaction, gaseous product is by the filtration of interior pipe, derive from trapezoidal hole and enter the gas collection chamber formed between double-jacket tube, high temperature pyrolysis coal gas in air collecting chamber on flowing, owing to there being the existence of blast cap, change the flow direction of coal gas by adjustment blast cap, coal gas is entered below catalytic bed, from top out, increase the contact area of coal gas and catalyzer, better reach dust removing effects; Finally, the solid particulate falls downward of filtering layer below spillway partly risen along with pyrolysis coal gas drops down onto in the storage tank of below, thus reaches the separation of solid, liquid, gas; When the catalyzer in catalytic bed needs to change, the catalyzer of inactivation can be discharged from outlet, then catalyzer is put into from the opening for feed of the left and right sides, top of catalytic bed, both the replacing of catalyzer had been facilitated, again can in time supply, more catalyst changeout in the reaction, do not need reaction to stop changing again, raise the efficiency.
