Abstract

The utility model relates to a novel multifunctional biomass gasifier which comprises an outer water cavity (1), a water pipe (2), a smoke dissolving chamber (3), an inner water chamber (4), a water inlet pipe (5), a gasifying chamber (6) and a water outlet pipe (7). The water inlet pipe (5) is communicated with the outer water chamber (1), the water pipe (2) is communicated with the outer water cavity (1) and the inner water chamber (4), and the smoke dissolving chamber (3) is located between the outer water cavity (1) and the inner water chamber (4) and communicated with the gasifying chamber (6). The water pipe in the prior part is replaced by the inner water chamber, so that the contact area between a water area and the gasifying chamber is increased greatly, the hot water yield and the effluent temperature are improved greatly, the oxidizing speed of a material for preparing the gasifying chamber is effectively reduced, and the service life of the biomass gasifying furnace is prolonged greatly. In addition, the outer water chamber is increased to completely cool combustible gas. Compared with the prior art, the temperature of the outer wall of the biomass gasifier is reduced and the use security of the biomass gasifier is effectively improved.

Description

A kind of Multifunction biomass gasifying furnace

Technical field

The utility model relates to a kind of stove and accessory that utilizes wood chip, agricultural crop straw and other carbon containing biomass fuel production combustion gas, is specially a kind of Multifunction biomass gasifying furnace.

Background technology

Biomass gasifying furnace is to utilize biomass fuel (such as agricultural crop straw, straw, forestry waste etc.) to burn under anoxic condition, makes most of combustiblesubstance convert H to ₂, CH ₄, the inflammable gass such as CO can be for cooking and heating.Inflammable gas need to purify and cooling process before burning usually.ZL 200820053457.9 discloses a kind of like this biomass gasifying furnace, this vapourizing furnace is by the gasification cavity, water pipe is changed smoke chamber, and water cavity forms, gasification chamber produces inflammable gas, water pipe places gasification chamber inside and communicates with water cavity, and cold water is introduced into water cavity and then enters water pipe, and the water in the water pipe is discharged through outlet after becoming hot water under the hot inflammable gas effect, change smoke chamber and communicate with gasification chamber, can carry out purifying treatment to inflammable gas.This kind mode can be carried out to a certain degree cooling process to inflammable gas, simultaneously can provide a part of hot water, but because the contact area of water pipe and inflammable gas is limited, so that cooling performance is undesirable, the hot water effluent lead and leaving water temperature(LWT) not high, what gasification chamber adopted in addition all is the plain carbon stool material, thickness is relatively thin, easily oxidation under high temperature action, so the vapourizing furnace of this kind mode is also undesirable work-ing life.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming that exists in the prior art, and a kind of inflammable gas good cooling results is provided, and the hot water effluent leads with leaving water temperature(LWT) high, the Novel biomass gasification furnace of long service life.

The utility model is achieved through the following technical solutions:

For realizing foregoing invention, designed a kind of Multifunction biomass gasifying furnace, comprise outer water cavity 1, cross water pipe 2, change smoke chamber 3, internal layer water cavity 4, water inlet pipe 5, gasification chamber 6, rising pipe 7, water inlet pipe 5 communicates with outer water cavity 1, cross water pipe 2 and be communicated with outer water cavity 1 and internal layer water cavity 4, change smoke chamber 3 and between outer water cavity 1 and internal layer water cavity 4 and with gasification chamber 6, be communicated with.Rising pipe 7 passes outer water cavity 1 and changes smoke chamber 3, and connects with internal layer water cavity 4.

The beneficial effects of the utility model are:

1. the water pipe that has replaced prior art with interior water cavity, greatly increased the contact area of waters and gasification chamber, increase substantially hot water effluent's amount and leaving water temperature(LWT), effectively reduced simultaneously the oxidation rate that gasification chamber is made material, increased substantially the work-ing life of biomass gasifying furnace.

2. increased an outer water cavity, can fully cool off inflammable gas, compared with prior art, reduced the outside wall temperature of biomass gasifying furnace, Effective Raise the safety in utilization of biomass gasifying furnace.

Description of drawings

The utility model will be further described below in conjunction with drawings and Examples:

Fig. 1 is the utility model structural representation;

1. outer water cavity is 2. crossed water pipe, 3. changes smoke chamber, 4. internal layer water cavity, 5. water inlet pipe, 6. gasification chamber, 7. rising pipe

Embodiment

As shown in Figure 1: a kind of Multifunction biomass gasifying furnace, comprise outer water cavity 1, cross water pipe 2, change smoke chamber 3, internal layer water cavity 4, water inlet pipe 5, gasification chamber 6, rising pipe 7, water inlet pipe 5 communicates with outer water cavity 1, cross water pipe 2 and be communicated with outer water cavity 1 and internal layer water cavity 4, change smoke chamber 3 and between outer water cavity 1 and internal layer water cavity 4 and with gasification chamber 6, be communicated with.Rising pipe 7 passes outer water cavity 1 and changes smoke chamber 3, and connects with internal layer water cavity 4.During concrete the use, place the biomass fuel of gasification chamber 6, can discharge a large amount of heats when under anoxic condition, burning, the inflammable gas of its generation also can be taken away in a part of heat and the entering into smoke chamber 3 and purify, cold water enters into outer water cavity 1 from water inlet pipe 5, the heat that absorption discharges from the inflammable gas of changing in the smoke chamber 3, water temperature obtains rising, then enter into internal layer water cavity 4 by crossing water pipe 2, the heat that absorption discharges during from the biomass fuel anoxycausis, water temperature further obtains fast rise, is discharged to the hot water storage bucket from rising pipe 7 at last.

The above; be a specific implementation of the present utility model, do not represent all implementations of the utility model, every structurally similar with the utility model; the concrete application of identical or similar solution is arranged, all within protection domain of the present utility model.
