Description
Technical field
The utility model relates to a kind of pit kiln, is specially a kind of built-up type pit kiln of being built by laying bricks or stones by refractory materials.Pit kiln especially for destructive distillation premolding formed coke.
Background technology
In the prior art, though it is various by the pit kiln structure that refractory materials is built by laying bricks or stones, but can be divided into two kinds of internal heat type and external-heats from combustion system, internal heat type stove wherein, as various coking chambers, it is owing to exist the defective that the coking cycle is long, production efficiency is low, raw coal serious waste of resources, the byproduct rate of recovery are low etc. is difficult to overcome, thereby banned by country.And external-heat coking furnace shaft volume is little, and the coking cycle is short, and the wasting of resources is few, and byproduct easily reclaims and can continuous production, thereby is subject to people's attention in recent years.But external-heat coke oven ubiquity temperature inequality in the stove, defectives such as coke quality instability.Chinese patent 02244129 discloses " a kind of device systems of producing casting formed coke ", a kind of Formed Coke Furnace is disclosed in this device systems, this stove is made up of one or more single stove, and each single stove is built by laying bricks or stones by refractory materials and is formed, single stove comprises that a bottom is the oblique coking chamber of 20-50 degree angle lapping and places the combustion chamber coking chamber tilting bottom under, and the raw material in the coking chamber is heated by combustion chamber and each coupled flue.This stove comes down to old horizontal coke-oven and changes the bottom into after skewed product, and it does not break away from the above-mentioned defective that existing external-heat stove exists.And because of this stove is heated by the bottom, the interior raw material of stove is subjected to thermoae unbalanced, though both sides are provided with vertical flue in stove, does not solve root problem.It is longer that also there is the charing cycle in it in addition, problems such as unstable product quality.Chinese patent 95226398 discloses a kind of " vertical continuous coke oven ", this stove mainly comprises several coking chambers and coking chamber both sides independently upper and lower separately layer combustion chamber composition, each combustion chamber is just fired distribution chamber, horizontal quirk etc. by level again and is formed, and wherein horizontal quirk communicates with coking chamber.Though the structurally more aforementioned stove of this coke oven has certain advantage, it has adopted the internal heat type coke making process, and it is that the high temperature hot gas in the combustion chamber is imported coking chamber through hot air vents, and the coking coal in the coking chamber is directly roasted the destructive distillation coking.Though this mode has certain advantage than directly burning at coking chamber, but it is not big from the raw coal loss on ignition that has overcome the existence of internal heat type stove in fact, the volatilization composition is difficult to reclaim in the coal, defectives such as the wasting of resources is bigger, and the tar composition in the coal emits objectionable impurities easily in combustion processes, and environment is caused severe contamination.
Summary of the invention
The utility model has designed a kind of built-up type Formed Coke Furnace at above-mentioned the deficiencies in the prior art, and it is unbalanced that it has solved the external-heat furnace interior temperature of prior art, deficiencies such as coke quality instability.Avoided the internal heat type heat size easily to cause deficiencies such as burning, waste resource, contaminate environment again.
Built-up type Formed Coke Furnace of the present utility model comprises the combustion chamber of coking chamber and coking chamber both sides at the bottom of a slope is arranged at the coking chamber bottom, a sealing partition wall being arranged between coking chamber and the combustion chamber wherein, is provided with gas combustion apparatus in side wall of combustion chamber.
External-heat Formed Coke Furnace of the present utility model is with the alternate setting with the combustion chamber of coking chamber, and between the two, adopt closed partition wall that coking chamber and combustion chamber are separated, heat and gas combustion apparatus is set at sidewall of combustion chamber, make the interior formed coke molding mass of coking chamber realize the destructive distillation of real meaning, the raw material of having avoided the internal heat type destructive distillation to cause burns and loses and the spontaneous combustion of fugitive constituent and the atmospheric pollution that the tar burning forms.Adopt the alternate separation setting of combustion chamber and coking chamber, and the equal combuster in the both sides of every coking chamber, make uniformity of temperature profile in the coking chamber, the formed coke steady quality blackhead Jiao etc. can not occur, and the dry distillation gas in the coking chamber is easy to recovery.
The coking chamber of described external-heat Formed Coke Furnace and the cross section of combustion chamber are rectangle, and gas combustion apparatus places on two longitudinal side walls of combustion chamber opposite side and is and is symmetrical arranged.
Adopt the body of heater of square-section to help heat passage between coking chamber and combustion chamber, gas combustion apparatus is symmetricly set on the longitudinal side wall wall of two opposite sides of combustion chamber and helps uniform distribution of temperature in the combustion chamber.
Described external-heat Formed Coke Furnace, its sidewall of combustion chamber are provided with two covers or the above gas combustion apparatus of two covers at least, and along sidewall of combustion chamber from top to bottom or layering setting from bottom to top.
Gas combustion apparatus and layering setting are in the vertical overlapped in this employing more, help improving the temperature of combustion chamber and coking chamber, and control and regulate the temperature of each level easily and it is kept in balance.
Described external-heat Formed Coke Furnace is isolated burning zone in inside, combustion chamber from vertically being divided into several, and each isolates the gas combustion apparatus of the respectively corresponding level of burning zone, and each is isolated between the burning zone and is connected by ventilating pit.
The combustion chamber is divided into the gas combustion apparatus that several isolation burning zones that are interconnected and each are isolated the corresponding level of burning zone, the setting of this structure can with in the combustion chamber from vertically by the temperature subregion, and can implement to it at any time.Correspondingly can carry out subregion, and be divided into dryer section, preheating section, retort section and the stewing section of heat etc. thus the charing room temp.Can guarantee formed coke coking quality.
The ventilating pit quantity that this external-heat Formed Coke Furnace is isolated between the burning zone increases progressively from bottom to top.
Help to make the combustion chamber ventilation smooth and easy, keep the temperature-stable of each section.
