Description
The utility model relates to a kind of hot-blast stove of using that can add hot-air and cold water simultaneously more.
This hot-blast stove is applicable in the winter time and is installed in the various import supply warm braws that need the heating place, particularly be applicable to the air inlet of coal mine, usefulness toward the fresh warm braw of delivered downhole, and can burn hot water simultaneously for multiple use, burn boiling water for drinking, reach the purpose of multi-use, comparing with existing hot-blast stove in addition, it is rational in infrastructure to have, air, flue gas flow are reasonable, adopt thermal efficiency advantages of higher.
According to the knowledge of the applicant, present this version many still belong to not having with hot-blast stove has.
The purpose of this utility model will provide a kind of aforesaid hot-blast stoves of using exactly, solves the problem of multi-use.
The hot-blast stoves of using by burner hearth (1) more, anterior heat exchanger (10), middle part heat exchanger (12), rear portion heat exchanger (13), flue gas flow channel outlet (16), air flow channel import (15), air flow channel outlet (14), boiler (7), boiled water pot (5), adjustment doors (6) retractor device (19), face arch (23) rear arch (21), chain (20), dirt-excluding groove (22) is formed, it is characterized in that the burner hearth (1) that is built into refractory brick is connected together with anterior heat exchanger (10) block, and leave expansion joint (8), to solve the problem of thermal expansion, anterior heat exchanger (10), middle part heat exchanger (12), rear portion heat exchanger (13), air flow channel outlet (14), air flow channel import (15), flue gas flow channel outlet (16), be welded into an integral body.
Described how it is characterized in that with hot-blast stove burner hearth (1): furnace wall (4) is built into refractory brick, also is provided with fire bars (2), fire door (3).
Described anterior heat exchanger, adopted improved plate type heat exchanger, it is characterized in that it makes with several rectangular shaped as frame box bodys, because of it is arranged on the high-temperature region of burner hearth, for accelerate the heat exchanger radiating rate its belly weld again fin several, and be wiped with fire clay (9) and heat exchanger burnt out preventing on the direct shock surface of flue gas, an end of anterior heat exchanger is provided with retractor device (19) to eliminate the harm that thermal stress causes.
Described middle part heat exchanger (12), rear portion heat exchanger (13) adopt pipe heat exchanger, and the end at pipe also is provided with telescopic head (11) equally, and so-called telescopic head is a ring head, acts on identical with retractor device.
Described boiled water pot (5), burning the boiling water that can be for drinking, and it is arranged on the furnace wall (4), heats by the boiled water pot center by the flue of drawing in the burner hearth, and by-pass valve control is installed.
Described boiler (8) can burn heat for multiple use with cold water, is arranged on many tops with hot-blast stove, and it can determine the aperture area of furnace roof as required.
Described adjustment doors (6) is to make with boiler plate, is installed in furnace wall (4) top, can prevent the flue-gas temperature superelevation, to making heat exchanger overheated, can regulate aperture, enters a small amount of cold air, reduces flue-gas temperature.
Primary air fan is shut down suddenly in addition, and is difficult to resume operation immediately, but the standard-sized sheet adjustment doors, make the burner hearth waste heat thus door enter atmosphere, unlikely continuation barbecue heat exchanger.
Described many with hot-blast stove except that Fig. 1, Fig. 2, Fig. 3, hand feed shown in Figure 4 manually remove the gred the formula, also can design chain charging chain slagging-off formula shown in Figure 5, latter's structure is to be provided with face arch (23), rear arch (21), chain (20) dirt-excluding groove (22).
Further describe in conjunction with the accompanying drawings:
Fig. 1 is the hot-blast stove front views of using more;
Fig. 2 is the cutaway view of Fig. 1 along the A-A line;
Fig. 3 is the cutaway view of Fig. 1 along the B-B line;
Fig. 4 is the cutaway view of Fig. 1 along the C-C line;
Fig. 5 is many schematic diagrames that adopt chain-type charging and slagging-off with hot-blast stove;
In conjunction with Fig. 1, Fig. 2, Fig. 3, the left end of anterior heat exchanger is provided with retractor device, and its structure is conventional stuffing box, and its associated methods is to compress and weld filling asbestos material (17) in the stuffing box (19), mixes with air and is as the criterion can completely cut off flue gas.
Many its flow process of flue gas flow channel directions shown in the single line arrow among Fig. 1: burner hearth (1) → anterior heat exchanger (10) top → anterior heat exchanger (10) bottom → middle part heat exchanger (12) bottom → middle part heat exchanger (12) top → rear portion heat exchanger (13) top → rear portion heat exchanger (13) bottom → flue gas flow channel outlet (16), deduster, air-introduced machine chimney → atmosphere with hot-blast stove.
Flue gas is done three backhauls and is flowed, and long flow process is arranged, and can make flue-gas temperature be reduced to ideal value, and important economic value is arranged.
The many directions of its flow process of air flow channel shown in the double-lined arrow among Fig. 1 with hot-blast stove:
Primary air fan → air flow channel inlet (15) → rear portion heat exchanger (13) Lower Half → middle part heat exchanger (12) Lower Half → anterior heat exchanger (10) bottom → anterior heat exchanger (10) top → middle part heat exchanger (12) first half → rear portion heat exchanger (13) first half → air flow channel outlet (14) → heating zone.
How to compare with existing hot-blast stove with hot-blast stove, its circulation of air circuit is long, and belong to tandem circulation circuit, pass through all radiating surfaces of heat exchanger uniformly, avoided the phenomenon of radiator hot-spot, and in the whole air flow process, only turn a turning of 180 °, reduced the stove internal resistance, reduced the power consumption of primary air fan, suitable economic worth has been arranged equally.
