Abstract
The invention discloses a gas kiln provided with a radiation pipeline device, which comprises a kiln body (1), a kiln door (2), gas nozzles (3) and a flue (6), wherein the kiln door is located at one end of the kiln body; the gas nozzles are arranged on a side wall of the kiln body; fire sucking holes (5) are formed at the kiln bottom of a heating chamber in the kiln body (1); a plurality of radiation pipelines (4) are arranged on an inner wall of the heating chamber in the kiln body (1); one end of each radiation pipeline is connected with the fire sucking holes at the kiln bottom; and the other end of each radiation pipeline is communicated with the flue (6). According to the gas kiln, the residence time of flames can be prolonged in the kiln by a system during a working period of the kiln, and sufficient heat exchange is conducted on a workpiece, so that the heat efficiency is improved, and purposes of high efficiency and energy conservation are achieved.
Description
Technical field
The invention belongs to batch (-type) gas burning kiln technical field, relate in particular to a kind of gas burning kiln that is provided with radiation pipeline device.
Background technology
Periodic kilns the kiln is the conventional calcination equipments of industry such as pottery.At present, combustion gas drawer type and the shuttle kiln of use all belong to periodic kilns the kiln, due to periodic kilns the kiln simple in structure, expenditure of construction is low, have a narrow range of temperature in kiln and produce the features such as flexible adjustment is convenient, therefore, be widely used in industries such as daily, technique, sanitary ceramics.This kiln is flexible to burning till of the little multi-assortment production of batch, is the requisite heating of these industries and calcination equipment.But this kiln is because flame is short at kiln residence time, cannot carry out sufficient heat exchange with workpiece, most of heat is directly discharged in atmosphere through flue, waste, add in addition the factors such as upper kiln heat radiation, the thermal efficiency only has 3 percent to five, and energy consumption accounts for 40 percent left and right of Production of Ceramics cost, is the key issue reducing production costs in Production of Ceramics so save the energy.Although some kilns have been taked a lot of measures on energy-conservation, because structure and the mode of heating of kiln determine, energy-saving effect is still undesirable.
Summary of the invention
The present invention is directed to the deficiency that existing combustion gas periodic kilns the kiln exists, propose a kind of gas burning kiln that is provided with radiation pipeline device, it can extend hot flue gas heating process to workpiece in kiln, effectively increases heat exchanger time, the thermal efficiency that improves kiln, reaches energy-saving and cost-reducing object.
The present invention realizes the technical scheme that above-mentioned purpose takes: a kind of gas burning kiln with radiation pipeline device,
Comprise kiln body, fire door, fuel burner nozzle and flue, fire door is positioned at one end of kiln body, fuel burner nozzle is arranged on the side wall of kiln body, at the heating clamber madial wall of described kiln, many group radiation pipelines are set, on at the bottom of kiln in heating clamber, be provided with suction fire hole, one end of every group of radiation pipeline with at the bottom of kiln on corresponding suction fire hole connect, the other end is all communicated with flue.
Radiation pipeline of the present invention is along every group of independent installation of heating clamber sidewall of kiln, and pipeline group is parallel to each other.
The cross section of radiation pipeline of the present invention can be designed to rectangle, circle or polygon.
The present invention owing to being provided with the good radiation pipeline of many group heat conductivilitys in heating clamber, and one end of pipeline is connected with the suction fire hole on kiln body, and the other end is communicated with flue, thus, forms a set of complete flame and flue and connect system.In the time that kiln is worked, flame completes after workpiece essential convection current and radiation heating in firing chamber, hot flue gas with a large amount of waste heats is entered to the radiation pipeline of setting through inhaling burner, continue to workpiece conduction and radiation heating, finally by air flue emission kiln discharge by the good radiant tube of heat conductivility.In order to make radiant tube more effectively conduct heat, the cross section of radiant tube is designed to rectangle, circle or irregular polygon, and these shapes not only can increase the heat-conducting area of radiant tube, improves heat conduction efficiency, but also can account for less heating chamber space.The kiln that employing is provided with radiant tube structure can allow flame carry out sufficient heat exchange to workpiece, effectively increases heat exchanger time, improves the thermal efficiency of kiln.Can significantly save the energy compared with original technology, reduce and burn till cost.

Detailed description of the invention
With reference to the accompanying drawings, describe specific embodiments of the invention in detail.
As Fig. 1. as shown in Fig. 2, Fig. 3, the gas burning kiln that is provided with radiation pipeline device of the present invention,
Comprise kiln body 1, fire door 2, fuel burner nozzle 3, radiation pipeline 4, inhale fire hole 5 and flue 6, fire door 2 is positioned at one end of kiln body 1, fire door 2 close after at the airtight heating clamber of the interior formation of kiln body 1.On the side wall of heating clamber, be provided with fuel burner nozzle 3.In heating clamber, by sidewall, many group radiation pipelines 4 are set, in order to improve the heat-conducting area of radiation pipe, improve pyroconductivity, radiant tube can be selected the thin-walled silicon nitride combined silicon carbide that heat conductivility is good. and recrystallized silicon carbide material pipe composition radiation pipeline 4, cross section can be designed to rectangle, circle or polygon.Installation method is: by the interior heating clamber sidewall of kiln body 1, radiation pipeline is independently installed, one end of every group of radiation pipeline 4 with at the bottom of kiln on corresponding suction fire hole 5 connect, because the temperature of heating clamber needs uniformity, quantity and the size of every group of radiation pipeline 4 and the suction fire hole 5 of corresponding connection, long-pending and the suction fire amount setting according to bottom of heating chamber, can establish one or more suction fire holes 5, the other end is all communicated with flue 6, forms thus a set of complete hot flue gas and flue and connects system.
Workflow of the present invention is: by fuel burner nozzle 3 by the heating clamber of flame spirt kiln, heated workpiece is heated and burnt till, flame completes after the convection current radiation heating of workpiece in heating clamber, hot flue gas with a large amount of waste heats enters the radiation pipeline 4 of setting through inhaling burner 5, continue to conduct heat in heating clamber by the good radiant tube 4 of heat conductivility, the last hot flue gas that completes whole heat exchanging process in kiln can expel from kiln through flue 6, thereby reaches energy-saving and cost-reducing object.
