Description

A kind of water jacket hot tube heat exchanger

Technical field:

The utility model relates to the water jacket hot tube heat exchanger that a kind of producer gas generator uses

Background technology:

At Coal Chemical Industry industry or the employed producer gas generator of city centralizedly supply coal gas, utilize coal burning and saturated steam to react and prepare coal gas, water jacket is the major parts of producer gas generator, coal portion's burning within it.Present water jacket is by annular seal head, inside and outside cylindrical shell, water inlet pipe, rising pipe etc. constitute up and down, form water cavity between the inside and outside cylindrical shell, feed recirculated water in the water cavity, coal burns in inner barrel, and the effect of water cavity is to prevent the at high temperature bonding inwall of coal and prevent that inwall from burning out.Is the burning collection chamber on the top of water jacket, it is refractory materials to be built by laying bricks or stones into cylindric, is the steel plate outer cylinder body at the outer wall of refractory materials, makes refractory materials and steel plate outer cylinder body be connected to form an integral body.Be provided with a coal feeding pipe at burning collection chamber upper top cover, sidewall is provided with an escape pipe in burning collection chamber upper end, internally fired high temperature coal of water jacket and water vapour reaction make coal gas, and coal gas is escaped and enter in the gas collection bag in order to using by the escape pipe of upper end.Because waste-heat recovery device is not established on water jacket top, the gas temperature of being discharged by escape pipe is still very high, enters gas collection bag postcooling and discharges, and these heat energy waste, and is economical inadequately.

The utility model content:

The purpose of this utility model provides a kind of water jacket hot tube heat exchanger that can absorb heat energy, reduction exhaust temperature, save the energy.

To achieve these goals, the utility model comprises: coal feeding pipe, upper top cover, escape pipe, rising pipe, water inlet pipe, outer cylinder body, inner barrel, the inner barrel concentric locking collar is inner barrel outside, outer cylinder body and inner barrel are fixedly attached to the top of water jacket after sealed at both ends, form the burning collection chamber, top and the bottom at outer cylinder body are set with rising pipe and water inlet pipe respectively, be connected by the transition of pipe nipple cylindrical shell between upper top cover and the inner barrel, coal feeding pipe is arranged in the middle of the upper top cover, escape pipe is positioned at the pipe nipple cylinder lateral wall, it is that inwall at inner barrel evenly is set with some heat transfer tubes, and heat transfer tube is provided with heat absorbing sheet.Like this, when work, cold water enters into space between outer cylinder body and the inner barrel by the water inlet pipe of its underpart, and is continuously introduced in the heat transfer tube, and heat absorbing sheet, heat transfer tube and inner flowing water thereof absorb the heat of coal gas of high temperature, coal gas of high temperature is lowered the temperature, low temperature coal gas is discharged by escape pipe, and the flowing water behind the absorption heat is discharged by rising pipe, supplies with the device or the personnel that need hot water and uses, made full use of heat energy, reduced exhaust temperature, saved the energy.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is an internal structure synoptic diagram of the present utility model.

Embodiment:

As shown in Figure 1, the utility model comprises: coal feeding pipe 9, upper top cover 8, escape pipe 7, rising pipe 5, water inlet pipe 2, outer cylinder body 4, inner barrel 3.Inner barrel 3 concentric locking collars are in outer cylinder body 4 inside, the height of outer cylinder body 4 and inner barrel 3 should be identical, outer cylinder body 4 and inner barrel 3 are fixedly attached to the top of water jacket 1 after sealed at both ends, form the burning collection chamber, form water cavity 12 between outer cylinder body 4 and the inner barrel 3, outer cylinder body 4 should slightly slope inwardly so that coal fully burns with inner barrel 3.Be set with rising pipe 5 and water inlet pipe 2 respectively in the top and the bottom of outer cylinder body 4, rising pipe 5 and water inlet pipe 2 are communicated with water cavity 12.Be connected by 6 transition of pipe nipple cylindrical shell between upper top cover 8 and the inner barrel 3, coal feeding pipe 9 is used for adding coal in the middle of being arranged on upper top cover 8 in stove.Escape pipe 7 is positioned at pipe nipple cylindrical shell 6 sidewalls, is used to discharge the coal gas of preparation.Inwall at inner barrel 3 evenly is set with some heat transfer tubes 10, heat transfer tube 10 is communicated with water cavity 12, and heat transfer tube 10 should be provided with inner barrel 3 inner wall surrounding homogeneous layers row, and the longer lower floor in upper strata is shorter, the internal heads of heat transfer tube 10 is lower slightly, so that flow into recirculated water and discharge hot gas.On heat transfer tube 10, evenly be provided with heat absorbing sheet 11, to improve heat absorption efficiency to heating gas.Inner barrel, heat transfer tube, heat absorbing sheet, coal feeding pipe, upper top cover etc. all adopt the boiler steel processing and fabricating.
