Abstract

The utility model relates to a gas producer which is the improvement on a WG type furnace. The utility model comprises a full water jacket which is composed of two parts of a water jacket, is used for generating two kinds of pressure, and is matched with a vapor collecting bag to realize the complete self feed of vapor. A gasifying agent, which is formed by that compressive vapor is directly sprayed into a venturi-shaped saturated air pipe by a regulation system, and is mixed with the air, enters the producer. The utility model has the advantages that saturation temperature is sensitively regulated, hysteresis phenomenon is eliminated, an explosion risk which is caused by sudden power failure and the backflow of gas generated on the air pipe in action, and production safety is ensured.

Description

Producer gas generator

The utility model relates to the more atmospheric fixed bed WG moulded coal gas producer of a kind of domestic use.

This producer gas generator (seeing Fig. 1) is whole full jacket structure for water.Saturated air pipe 3 is simple straight tubes, and air intlet 1 is at the body of heater top.Air 2 is also at the top.Top-side has softening water overflow port 4, simultaneously the limiting water level height.This structure exists following shortcoming:

1. the temperature of saturation (coming down to embody airborne water content) of an important indicator-air admission producer during producer is produced be by furnace water jacket that produce with the atmospheric steam same pressure of air (about 800MM water column), the air that entered by air intlet 1 mixes generation at the water jacket headspace.The adjusting of temperature is how much to work by the water yield that adds water jacket.The amount of water multi-overflow amount greatly then low generation of water temperature steam is few, and temperature of saturation is low; Otherwise the few spillway discharge of the amount of water high generation of water temperature steam at least is many, the temperature of saturation height.Because the water capacity of water jacket is very big, the change of the temperature of water needs long time, thereby can not be in time adapts with the change of gas production load and produce hysteresis phenomenon.Will influence the quality of coal gas like this and produce operational difficulty.

2. in order to keep the safety in production, furnace water jacket can not lack of water, must keep from overflow port overflow softening water.Thereby to consume the softening water of a large amount of preciousnesses.Reuse as saving softening water, then must increase the softening water cooling-cycle device that a cover capacity is about 80M, need to increase investment, working cost, and increased managerial trouble.

3. because can only produce atmospheric steam, can not provide and insert the steam that prevents the 0.3Mpa pressure of the vapour curtain usefulness that coal gas leaks when pricker is inserted in the pricker hole, and need to rely on outer for steam.

4. because can only produce atmospheric steam, the steam that can not provide pressure prevents and may withstand the blast that coal gas adverse current air feed tube road may cause when having a power failure suddenly by the saturated air pipe of injecting tube and venturi shape, to guarantee safe operation.

The purpose of this utility model provides a kind of improved body of heater, is used to overcome aforesaid various shortcoming and deficiency.

The purpose of this utility model is achieved in that the water jacket of producer is made into water jacket cylindrical shell and two parts of water jacket top cover from integral body.And increase a plenum chamber that links into an integrated entity with convection tubes with cylindrical shell.Header field is made non-pressure vessel, adds softening water and produces in the direct entrained air of atmospheric steam.Shell portion is made the container that can bear 0.3Mpa pressure, adds the steam that softening water produces 0.3Mpa pressure from plenum chamber.And a covering device that utilizes original control softening water flow controls the steam flow that come by plenum chamber, makes in its saturated steam pipe that directly enters injecting tube and venturi shape with after the air mixed and enters producer.This temperature that just can accomplish saturated air does not have hysteresis phenomenon.A softening water air feedization is required, does not have the overflow waste.Also provide to prevent to prevent the source of the gas of the steam curtain that coal gas leaks when pricker is inserted in the source of the gas of dangerous injecting tube and plug in pricker hole, accomplished the effect that steam is self-supporting fully because of power failure suddenly may set off an explosion.

The utility model be because main only the need be divided into two parts with original whole water jacket, increases a plenum chamber that links into an integrated entity with convection tubes with cylindrical shell and straight saturated air pipe is made into venturi shape.Utilize a covering device of original control softening water flow to control steam flow again.Therefore be easy to realize.

Concrete structure of the present utility model can be provided by following examples and accompanying drawing 2.

Fig. 2 is the sketch that makes according to the improvement project that the utility model proposes.Illustrate according to concrete device and the working condition that the utility model proposes below in conjunction with Fig. 2:

This device comprises water jacket furnace top cover 1, water jacket cylindrical shell 2, vapor collection drum 3, saturated steam pipe 4, steam ejection pipe 5, convection tubes 6, gas inlet 7 is plugged in pricker hole 8, thermometer bulb 9, steam regulating valve 10,0.3Mpa pressure steam pipe 11, kapillary 12, atmospheric steam pipe 13, water inlet pipe 14, coal supply apparatus 16, gas exit 17, grate 18, furnace bottom 19, slag storehouse 20, stove leg 21.

Softening water enters water jacket furnace top cover 1 by water inlet pipe 14, and evaporation produces atmospheric steam, directly enters saturated air pipe 4 because quantity of steam is few by atmospheric steam pipe 13, can be used as basic need and does not regulate.Water jacket cylindrical shell 2 absorbs the steam of the radiant heat generation 0.3Mpa pressure of gasification layer from inwall.Come out by plenum chamber 3, spray into the saturated air pipe 4 of venturi shape by steam regulating valve 10 and steam ejection pipe 5, enter furnace bottom 20 after the mixing, grate 18 is in body of heater and gasification.When the coal gas load variations, cause the variation of air capacity.In order to keep temperature of saturation constant substantially, must rely on an original cover thermometer bulb 9 to control steam regulating valve 10 steam regulation amounts and realize by kapillary 12.Prevent that coal gas from may blow back into when having a power failure suddenly that blast main sets off an explosion is to borrow steam that pressure is arranged to withstand coal gas by the kinetic energy of injecting tube 5 ejections to flow backwards.Prevent from coal gas when plugging in pricker hole 8 plugs in pricker to leak to be the steam that will pressure be arranged from plenum chamber receive to plug in pricker hole 8 and produce the steam air curtains and realize.Because softening water only for producing steam usefulness, does not have overflow, therefore do not cause the softening water waste.
