Abstract

The utility model relates to a bake out furnace specifically relates to a carrier -free air heat energy bake out furnace, including the combustion chamber, the heat transfer room, preheating chamber and clean room, when combustion chamber burning fuel, just, heat the indoor heating nest of tubes of heat transfer, the dump heat of burning can and steam just from the first bank of tubes of discharging fume to the preheating chamber in, just, the nest of tubes that preheats in the preheating chamber has been heated, during the aqueous sodium hydroxide of the bank of tubes to clean room is just discharged fume from the second to the remainder of exhaust gas, because the gas after the burning of fuel such as coal mainly is sulphide, through with aqueous sodium hydroxide chemical reaction takes place after, the smoke stack emission is just followed to harmless gas, therefore, toast required heat energy, just, it passes and preheats the nest of tubes through being heated and come by fan output with the heating nest of tubes to import even plenum again into by the air admission air inlet housing. The utility model discloses a heat transfer room and preheating chamber messenger heat energy is make full use of more, and is more high -efficient, more energy -conserving, because the gaseous of heating intersect influence with toasting not have between the required steam, makes and toast safelyr, also more practices thrift the cost than having the conduction oil bake out furnace now, owing to setting up of clean room makes the emission of waste gas obtain purification, environmental protection more.

Description

A kind of carrier-free air heat energy oven

Technical field

The utility model relates to a kind of oven, relates to a kind of carrier-free air heat energy oven particularly.

Background technology

The oven used in the food-baking industries such as biscuit, bread, cake, for the consideration of health, healthy aspect, the air that can not allow combustion chamber contacts with the product be baked, therefore market just there is the oven needing to adopt heat conduction wet goods heat exchange medium, but conduction oil is not only expensive, and heating uses and also very easily produces danger in the environment of sealing, and the defect such as when also having work, the thermal efficiency is not high, heat temperature raising is slow first.

Summary of the invention

The purpose of this utility model is to provide a kind of safety, energy-saving and environmental protection, efficiently carrier-free air heat energy oven.

For achieving the above object, the utility model is by the following technical solutions:

A kind of carrier-free air heat energy oven described in the utility model comprises combustion chamber, Heat Room, preheating chamber and dirt pocket, above described combustion chamber, Heat Room is set, heating tube group is horizontally disposed with in Heat Room, described heating tube group is resistant to elevated temperatures carborundum tube composition, and each row's carborundum tube is arranged in interactive up and down, below combustion chamber, ash discharging chamber is set, the same side of combustion chamber and ash discharging chamber arranges dirt pocket, dirt pocket side is provided with chimney, dirt pocket is built with sodium hydrate aqueous solution, above dirt pocket, preheating chamber is set, about preheating chamber and Heat Room side by side, preheating chamber and Heat Room are separated by common refractory brickwork, economizer bank group is horizontally disposed with in preheating chamber, economizer bank group is made up of some economizer banks, each row's economizer bank is arranged in interactive, and docked with heating tube group by refractory brickwork, preheating chamber and Heat Room top arrange first row smoke pipe, first row smoke pipe connects preheating chamber and Heat Room, second row smoke pipe is set between preheating chamber and dirt pocket, second row smoke pipe one end connects preheating chamber, one end is submerged in the sodium hydrate aqueous solution of dirt pocket, above preheating chamber and Heat Room, inlet plenum is set, first row smoke pipe body is arranged in inlet plenum, at preheating chamber and inlet plenum side, even air compartment is set, fall down to arrange from being short to long air uniform plate from above on the side locular wall in air port in even air compartment, when combustion chambers burn fuel, just the heating tube group in Heat Room is heated, residue heat energy and the hot gas of burning are just discharged in preheating chamber from first row smoke pipe, just heated the economizer bank group in preheating chamber, remainder of exhaust gas just drains into the sodium hydrate aqueous solution of dirt pocket from second row smoke pipe, due to the mainly sulfide of the gas after the fuel combustions such as coal, through with sodium hydrate aqueous solution generation chemical reaction after, innocuous gas is just from smoke stack emission, therefore, heat energy needed for baking, just enter inlet plenum by air to import even air compartment again into and exported by blower fan through through be heated economizer bank group and heating tube group.

The utility model makes heat energy more make full use of by Heat Room and preheating chamber, more efficiently, more energy-conservation, due to heating gas and baking needed for hot gas between without cross influence, make baking safer, also more existing conduction oil oven is more cost-saving, be arranged so that the discharge of waste gas obtains purification, environmental protection more due to dirt pocket.

Accompanying drawing explanation

Fig. 1 is the structural representation of a kind of embodiment of the utility model.

Detailed description of the invention

As shown in Figure 1, a kind of carrier-free air heat energy oven described in the utility model comprises combustion chamber 1, Heat Room 2, ash discharging chamber 3, dirt pocket 4, preheating chamber 5, inlet plenum 6 and even air compartment 7, it is characterized in that, above described combustion chamber 1, Heat Room 2 is set, heating tube group 2-1 is horizontally disposed with in Heat Room 2, described heating tube group 2-1 is that resistant to elevated temperatures carborundum tube 2-11 forms, and each row's carborundum tube 2-11 arranges in interactive up and down, ash discharging chamber 3 is set below combustion chamber 1, combustion chamber 1 arranges dirt pocket 4 with the same side of ash discharging chamber 3, dirt pocket 4 side is provided with chimney 8, dirt pocket 4 is built with sodium hydrate aqueous solution, preheating chamber 5 is set above dirt pocket 4, preheating chamber 5 and Heat Room about 2 are side by side, preheating chamber 5 and Heat Room 2 are separated by common refractory brickwork, economizer bank group 5-1 is horizontally disposed with in preheating chamber 5, economizer bank group 5-1 is made up of some economizer bank 5-11, each row's economizer bank 5-11 arranges in interactive, economizer bank group 5-1 is docked with heating tube group 2-1 by refractory brickwork, preheating chamber 5 and Heat Room 2 top arrange first row smoke pipe 9, first row smoke pipe 9 connects preheating chamber 5 and Heat Room 2, second row smoke pipe 10 is set between preheating chamber 5 and dirt pocket 4, second row smoke pipe 10 one end connects preheating chamber 5, one end is submerged in the sodium hydrate aqueous solution of dirt pocket 4, above preheating chamber 5 and Heat Room 2, inlet plenum 6 is set, first row smoke pipe 9 body is arranged in inlet plenum 6, at preheating chamber 5 and inlet plenum 6 side, even air compartment 7 is set, fall down to arrange from being short to long air uniform plate 7-1 from above on the side locular wall in air port in even air compartment 7.
