Abstract

The utility model provides a gas furnace. A preheater is arranged at the front end of a gas inlet pipe; the preheater is internally divided into a gas inlet chamber and a gas outlet chamber; a buffer channel is formed outside a gas combustion chamber; gas is discharged from the gas channel and finally discharged from a system through the gas outlet chamber of the preheater. The gas furnace has the beneficial effects that due to the arrangement of the preheater and the buffer channel, a preheating process is omitted when the gas enters a combustion process, the non-completely combusted gas is further combusted through the preheater in a gas discharging process so as to prevent carbon monoxide pollution; due to the arrangement of the buffer channel, a space can be provided for continuously combusting excess gas passing through the combustion process to guarantee complete combustion of the gas so as to reduce the content of carbon monoxide directly discharged to the atmosphere.

Description

A kind of gas furnace

Technical field

The utility model belongs to heat treatment process equipment technical field, is specifically related to a kind of gas furnace.

Background technology

Along with scientific and technical development, people more and more require the direct utilization of the energy, traditional industrial furnace is all that electricity consumption carrys out work, this wherein the energy through several times conversion, loss is larger, so gas furnace meets the tendency, has had now a lot of industrial equipments directly to adopt fuel gas buring to carry out work, this has just saved energy Ji road conversion program, has improved the utilization rate of the energy.

Although the use of combustion gas has improved the utilization rate of the energy to a great extent, but also there are some problems, such as: burn insufficient, air-flow also enters no burning with regard to the direct problem such as emptying of outflow system, this is not only a kind of waste to the energy, and the carbon monoxide that imperfect combustion produces also has severe toxicity, colorless and odorless, near the personnel that are easy to making are poisoning unconsciously.

Utility model content

In order to address the above problem, the utility model provides a kind of gas furnace, and the technical scheme of employing is as follows:

A kind of gas furnace, by body of heater and fire door, form sealing chamber, described body of heater both sides are connected to gas pipeline (14), the enclosed cavity that described gas pipeline passes into body of heater and fire door formation by fuel burner nozzle is indoor, described body of heater is hollow, described body of heater upside is full of that insulation fibre, rear side are equipped with refractory brick, downside is high temperature castable, it is characterized in that: the air inlet front end of described gas pipeline is provided with preheater, and described preheater inside is provided with inlet plenum and exhaust chamber.

Further improve and be: below and the rear of described body of heater are provided with refractory brick, between the below of described body of heater and rear and described refractory brick, form buffer channel, and the sealing chamber that described buffer channel consisted of with body of heater and fire door communicating pipe communicates.

Further improve and be: described buffer channel is all connected with described preheater with gas pipeline, and described preheater top is provided with chimney, described preheater sidepiece connecting fan.

Further improve and be: described fire door is located on fire door track, and is connected with furnace door lifting device.

The beneficial effects of the utility model: the utility model is equipped with a preheater and buffer channel by setting, and then guarantee to save warm-up phase when combustion gas enters combustion phases, at exhaust phase, pass through again preheater, further not combustion gas completely of burning, to prevent carbon monoxide pollution, buffer channel is set and burns away to the space of unnecessary combustion gas through combustion phases, guarantee the completing combustion of combustion gas, thereby reduce to the carbon monoxide content directly discharging in atmosphere.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Fig. 2 is side schematic view of the present utility model.

Wherein: 1-fire door, 2-high temperature castable, 3-insulation fibre, 4-preheater, 5-body of heater, 6-fuel burner nozzle, 7-communicating pipe, 8-buffer channel, 9-blower fan, 10-chimney, 11-refractory brick, 12-fire door track, 13-furnace door lifting device, 14-gas pipeline.

The specific embodiment

In order to deepen understanding of the present utility model, below in conjunction with drawings and Examples, the utility model is described in further detail, this embodiment, only for explaining the utility model, does not form and limits protection domain.

A kind of gas furnace, by body of heater 5 and fire door 1, form sealing chamber, described body of heater 5 both sides are connected to gas pipeline 14, the enclosed cavity that described gas pipeline 14 passes into body of heater 5 and fire door 1 formation by fuel burner nozzle 6 is indoor, described body of heater 5 is hollow, described body of heater 5 upsides are full of insulation fibre 3, rear side is equipped with refractory brick 11, downside is high temperature castable 2, it is characterized in that: the air inlet front end of described gas pipeline 14 is provided with preheater 4, described preheater 4 inside are provided with inlet plenum and exhaust chamber, the below of described body of heater 5 and rear are provided with refractory brick 11, between the below of described body of heater 5 and rear and described refractory brick 11, form buffer channel 8, described buffer channel 8 communicated with the sealing chamber that body of heater 5 and fire door 1 form by communicating pipe 7, described buffer channel 8 is all connected with described preheater 4 with gas pipeline 14, described preheater 4 tops are provided with chimney 10, described preheater 4 sidepiece connecting fans 9, described fire door 1 is located on fire door track 12, and be connected with furnace door lifting device 13.

A kind of gas furnace that the utility model provides, during work, blower fan is accelerated to blow new air and is entered, contribute to the burning of combustion gas, combustion gas enters the inlet plenum of preheater, preheating reaches 45 ℃, enter into fuel burner nozzle, directly from 45 ℃ of burnings that heat up, save one section and from normal temperature, be raised to the time of 45 ℃, accelerated burning velocity, make combustion gas can have longer burning time in chamber, contribute to completing combustion, along with follow-up combustion gas enters chamber, not clean-burning combustion gas and the carbon monoxide that generates because of burn incompletely are from enter into buffer channel communicating pipe, in buffer channel, burn away, combustion gas and carbon monoxide are fully burnt, the heat of gained can partly enter chamber, part still guarantees follow-up burning in buffer channel, take full advantage of the energy, gas has flow to the exhaust chamber of preheater, heating, final step flow of process air, in the gas that further guarantees to discharge, do not contain carbon monoxide.

The beneficial effect of the present embodiment: a kind of gas furnace that the present embodiment provides, because the front end entering in combustion gas is provided with preheater, can slightly be permitted to extend the burning time in combustion chamber, reduce imperfect combustion, chamber also arranges buffer channel outward, by connecting communicating pipe, the space of giving the sufficient combustion gas of unburned and burning away because of not clean-burning carbon monoxide, finally by the exhaust chamber of preheater, discharge, during through preheater, do last processing, assurance combustion gas is fully burnt, and does not have a large amount of carbon monoxide to discharge.
