Description
Technical field
The utility model relates to a kind of pyrolysis oven, particularly relates to a kind of dual-heating mode pyrolysis oven.
Background technology
Traditional coal heat decomposition stove can be divided into internal heat type and external-heat: the high-temperature gas that the internal heat type pyrolysis oven utilizes the burning of coal or coal gas to produce 600 ~ 700 ℃ directly enters coal heat decomposition stove, makes coal pyrolysis at this temperature, obtains semicoke, coal gas and tar products.But traditional pyrolytic process of coal contains a large amount of nitrogen owing to passing in gas, has reduced caloric power of gas, causes gas quality poor, be unfavorable for the coal gas comprehensive utilization; Simultaneously, the coal gas amount significantly increases has also increased subsequent disposal difficulty and plant energy consumption, affects the economy of whole device.The heating medium of external-heat pyrolysis stove does not contact with feed coal, heat is imported in process furnace by furnace wall, for the raw material pyrolysis, thereby almost there is no nitrogen in the coal pyrolysis gas obtained, the quality of pyrolysis gas is better, but, because its heat is to be imported into by furnace wall, its thermo-efficiency is lower, and the investment cost of external-heat pyrolysis stove will be far above the internal heat type pyrolysis oven.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of dual-heating mode pyrolysis oven, and the quality that it does not affect coal gas is beneficial to the comprehensive utilization of coal gas, and the utilising efficiency of whole process heat is higher, and comprehensive energy consumption is low.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of dual-heating mode pyrolysis oven, it is characterized in that, it comprises effuser, gas collection umbrella battle array, furnace chamber, coking chamber, charing wall, coke discharging mouth, gas distribution chamber, the gas distribution chamber is positioned at the below of charing wall, coking chamber and charing wall are spaced, the both sides of each charing wall are symmetrical one group of thermal barrier external heat transfer device all, the coke discharging mouth is positioned at the below of gas distribution chamber, furnace chamber is positioned at the top of charing wall, gas collection umbrella battle array is positioned at the top of furnace chamber, and effuser is positioned at the top of gas collection umbrella battle array.
Preferably, described charing coping adopts the structure of block.
Positive progressive effect of the present utility model is: adopt the dual-heating mode pyrolysis oven can realize multiple heat-transfer medium: the internal heat type high-temperature medium can adopt high temperature circulation coal gas, also available other high temperature inert media; And add the external-heat heat transfer part, owing to directly not contacting with coal gas, form high-temperature heat carrier poor, complicated component therefore can use, as high-temperature gas, high-temp liquid or gas-liquid mixed state thermal barrier, can not affect the quality of coal gas, be beneficial to the comprehensive utilization of coal gas.And the coal gas amount significantly reduces, be convenient to subsequent disposal and deep processing; The utilising efficiency of whole process heat is higher, and comprehensive energy consumption is low, has good economy, reduces costs.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model dual-heating mode pyrolysis oven.
The principle schematic that Fig. 2 is flue gas external heat transfer in the utility model.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As depicted in figs. 1 and 2, the utility model dual-heating mode pyrolysis oven comprises effuser 1, gas collection umbrella battle array 2, furnace chamber 3, coking chamber 4, charing wall 5, coke discharging mouth 6, gas distribution chamber 8, gas distribution chamber 8 is positioned at the below of charing wall 5, coking chamber 4 is spaced with charing wall 5, the both sides of each charing wall 5 are symmetrical one group of thermal barrier external heat transfer device 7 all, coke discharging mouth 6 is positioned at the below of gas distribution chamber 8, furnace chamber 3 is positioned at the top of charing wall 5, gas collection umbrella battle array 2 is positioned at the top of furnace chamber 3, and effuser 1 is positioned at the top of gas collection umbrella battle array 2.The charing coping adopts the structure of block.
Body of heater adopts the upright dual-heating mode charring furnace type of furnace, is applicable to the beans pyrolysis of particle diameter >=3mm.Separated by some charing walls in stove, increased the useful volume of coking chamber; Charing wall bottom is the gas distribution chamber, and high temperature gas medium enters coking chamber thus, and the coal fallen with top carries out the internal heat type heat transfer, impels beans in the abundant pyrolysis of this, produces the coal tar gas stripping simultaneously; The downward-sloping certain angle of the air distribution port of gas distribution chamber, in case the tablet coal is to the obstruction of air distribution hole; Equal symmetrical one group (2) thermal barrier external heat transfer device in each charing wall both sides, as shown in Figure 2, high-temperature heat carrier is entered by bottom (top), indirectly beans is heated to (external-heat heating), temperature (from top to bottom) from bottom to top reduces successively, has realized the reasonable utilization of thermal barrier potential temperature, also can produce certain dimension temperature effect to internal heat type heated air medium simultaneously, guarantee pyrolysis temperature, extend the pyrolytic reaction time; The charing coping adopts the structure of block; the structure of block is stretched out charing wall main body certain distance slightly; cover the outer thermal barrier heat transmitter of wall; Main Function is more open when coal is fallen; be beneficial to coal gas stream by; improve heat transfer efficiency, also thermal barrier external heat transfer device is played a protective role, prevent that the beans fallen from covering impact on heat transmitter and conducting heat simultaneously.The gaseous media that internal heat type conducts heat enter the back segment operation thereby enter effuser, and the external-heat high-temperature heat carrier is directly discharged by heat transmitter top after finally carrying coal gas that pyrolysis produces and tar secretly and being collected by pyrolysis oven upper-part centralized ballute battle array.The semicoke that pyrolysis produces is discharged by pyrolysis oven bottom coke discharging mouth.
Those skilled in the art can carry out various remodeling and change to the utility model.Therefore, the utility model has covered various remodeling and the change in the scope that falls into appending claims and equivalent thereof.
