Abstract
A heat exchange type sloping bottom heating stove is mainly composed of a sloping bottom heating stove, a tail gas chamber, a heat exchange change-over device, a suction pipe, a main gas pipe, an auxiliary gas pipe, a preheated air outlet pipe, a secondary air pipe, a blast blower and a plurality of longitudinal stainless steel tubes and is characterized in that a set of heat exchange change-overdevice for collecting the tail gas residual heat is installed on the stove tail upper part of the sloping bottom heating stove, thus transferring most of the tail gas residual heat generated by the furnace combustion to the combustion air of the secondary air. The utility model improves the thermal efficiency and saves the energy resource.
Description
Affiliated technical field
The utility model belongs to a kind of heat-exchange type slanting bottom heating furnace in the machine industry.
Background technology
Its afterbody of traditional inclined-bottom heating furnace is not provided with the heat exchange conversion equipment of collecting using waste heat from tail gas, so this traditional inclined-bottom heating furnace using waste heat from tail gas can not utilize, wastes energy.
Summary of the invention
The purpose of this utility model is a kind of heat exchange conversion equipment that a cover collection using waste heat from tail gas is installed in inclined-bottom heating furnace stove tail upper design of design.The heat exchange conversion equipment is designed to elongated cylinder, uniform some vertical stainless steel tubes in the inside of elongated cylinder, a pump-line that leads to the outside, workshop is set in an end middle part of elongated cylinder, the other end communicates with the outlet of stove tail tail gas, one end of some vertical stainless steel tubes communicates with pump-line, and the other end communicates with the outlet of stove tail tail gas.On the periphery of elongated cylinder near an end projection of pump-line the preheated air outlet conduit is set, the preheated air outlet conduit is connected with the main combustible pipe road; On the outer garden face of elongated cylinder near an end projection of tail gas outlet the secondary air pipeline is set, the secondary air pipeline is connected with air blast.The course of work is: the high-temperature tail gas that the stove internal combustion produces by at the inner uniform some vertical stainless steel tube of elongated cylinder, in the process of stove inner exhaust gas uniform some vertical stainless steel tubes in by elongated cylinder of temperature about up to 700 ℃ is passed to heat the cold air of the secondary air that is full of elongated cylinder inside under the natural draft that pump-line forms.Cold air is preheating to about 600 ℃ and enters the main combustible pipe road from the preheated air outlet conduit, then enters again and participates in burning in the inclined-bottom heating furnace.High-temperature tail gas is drained from pump-line after by some horizontal stainless steel tubes, and its temperature is reduced to about 100 ℃.This shows that its most of waste heat is utilized the combustion-supporting cold air of passing to secondary air again by the heat exchange conversion equipment that is arranged on stove tail top.The said structure design has realized the purpose of this utility model.
The utility model has the advantages that the big portion of using waste heat from tail gas that the stove internal combustion is produced by the heat exchange conversion equipment that is arranged on inclined-bottom heating furnace stove tail top passes to the combustion-supporting cold air of secondary air.Improve the thermal efficiency, saved the energy.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a front view of the present utility model.
Fig. 2 is a vertical view of the present utility model.
Fig. 3 is a left view of the present utility model.
Fig. 4 is the A-A cutaway view of Fig. 1.
The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of heat-exchange type slanting bottom heating furnace mainly is made up of inclined-bottom heating furnace 7, exhaust gas chamber 4, heat exchange conversion equipment 3, pump-line 2, main combustible pipe road 1, pair gas pipeline 9, preheated air outlet conduit 8, secondary air pipeline 6, air blast 5, some vertical stainless steel tubes 10.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, inclined-bottom heating furnace 7 is oval domes, afterbody at inclined-bottom heating furnace 7 is provided with exhaust gas chamber 4, heat exchange conversion equipment 3 is installed on stove tail top at inclined-bottom heating furnace 7, uniform some vertical stainless steel tubes 10 in the inside of heat exchange conversion equipment 3, one end of some vertical stainless steel tubes 10 communicates with pump-line 2, and the other end communicates with the outlet of exhaust gas chamber 4.Endless belt position in heat exchange conversion equipment 3 two ends projectioies is provided with preheated air outlet conduit 8 and secondary air pipeline 6 respectively, preheated air outlet conduit 8 is communicated with main combustible pipe road 1, secondary air pipeline 6 is connected with air blast 5, and exhaust gas chamber 4 is communicated with the afterbody of inclined-bottom heating furnace 7.The course of work is: the high-temperature tail gas that inclined-bottom heating furnace 7 produces in heating process enters the exhaust gas chamber 4 that is located at the stove tail under the acting in conjunction of pressure reduction that the stove internal combustion produces and pump-line 2, enter uniform some vertical stainless steel tube 10 in the heat exchange conversion equipment 3 again from exhaust gas chamber 4, simultaneously air blast 5 combustion-supporting cold air that secondary is advanced phoenix is sent into the inner chamber of heat exchange conversion equipment 3 by secondary air pipeline 6, the combustion-supporting cold air of high-temperature tail gas and secondary air carries out exchange heat in heat exchange conversion equipment 3, in the process of stove inner exhaust gas uniform some horizontal stainless steel tube 10 in by heat exchange conversion equipment 3 of temperature about up to 700 ℃ heat is passed to the combustion-supporting cold air of the secondary air that is full of heat exchange conversion equipment 3 inner chambers.Combustion-supporting cold air is preheating to about 600 ℃ and enters main combustible pipe road 1 from preheated air outlet conduit 8, then enters participation burning in the inclined-bottom heating furnace 7 by paying gas pipeline 9 again.Tail gas is being drained from pump-line 2 by some horizontal stainless steel tubes 10 backs, and its temperature is reduced to about 100 ℃.Its most of waste heat is passed to the combustion-supporting cold air of secondary air in heat exchange conversion equipment 3.
Claims (2)
