CN2292250Y - Steam generator - Google Patents

Abstract

The utility model relates to a steam generator which can be matched with a steam iron, particularly a steam generator which uses coal, charcoal or gas, etc., as heat source. The utility model comprises a heating furnace and a pressure cooker. The utility model is characterized in that the inner space of the pressure cooker is provided with a set of heating pipes which are provided for passing by exhaust gas after combusting. Both ends of each heating pipe are respectively fixed on the bottom and the top surface of the pressure cooker, and the top surface of the pressure cooker is provided with an exhaust pipe which can contain the top openings of all the heating pipes. The utility model solves the problems that the exhaust heat of the exhaust gas of the existing steam generator can not be used, the consumed energy is large, and the combusted exhaust gas is easy to peripherad diffuse to pollute the environment.

Description

Steam generator

The utility model relates to a kind of steam generator that can be used with vapour iron.Particularly a kind of is the steam generator of thermal source with coal, charcoal or combustion gas.

In the existing medium and small clothing factory with the matching used steam generator of vapour iron, normally adopt electrical heating, it can only use in the comparatively sufficient area of supply of electric power, and price is higher.Chinese patent 92227325.1 provides the liquefied gas steam generator in the remote mountain village of shortage for electric power, but the pressure vessel in this steam generator only has a bottom heating surface, so the lower and waste gas of utilization rate that it has heat is dispersed and shortcomings such as contaminated environment easily towards periphery.

The purpose of this utility model is to overcome the shortcoming that exists in the above-mentioned prior art, providing a kind of is the energy-saving steam generator of fuel with coal, charcoal or combustion gas etc., make it have heat utilization efficiency height, contaminated environment less, and characteristics such as simple in structure, safe and reliable.

It is heating furnace and a pressure cooker that is positioned at heating furnace top of fuel with coal, charcoal or combustion gas etc. that the utility model steam generator includes one, its feature is: 1) inner space of pressure cooker has one group and can pass through for waste gas after burning, thereby to the heating tube of water in the pot and the further heating of vapour, the two ends of this heating tube are fixed in respectively on the bottom surface and end face of pressure cooker; 2) have a blast pipe that can contain the heating tube top end opening that the residence has on the end face of pressure cooker, so that enter atmosphere by the burnt gas of heating tube.

Pressure cooker in the utility model steam generator can have the arch bottom surface that can ride on heating furnace.

To and contrast accompanying drawing by embodiment below, the utility model will be further described below.

Have in the accompanying drawing:

Fig. 1 is the main cutaway view of the utility model steam generator;

Fig. 2 is the A-A cutaway view among Fig. 1.

Can see that from Fig. 1 and Fig. 2 the utility model steam generator includes a pressure cooker 2, has the steam valve 9 of safety valve 7, Pressure gauge 5, water intaking valve 4, discharged steam on the end face of this pot; Have dipperstick 8 on the side of pressure cooker; The inner space of pressure cooker has one group of heating tube 3 of arranging with vertical direction, the bottom of this pipe is fixed on the bottom surface of pressure cooker, the top is fixed on the end face of pressure cooker, and the heating tube top end opening is all contained by a blast pipe 6 that is positioned on the pot top, blast pipe has flaring expansion segment, is beneficial to contain all heating tube openings.

When using the utility model steam generator, put into water earlier from water intaking valve 4, what of inflow can be controlled by dipperstick 8, closes water intaking valve then, lights heating furnace 1, can produce steam by the heating to pot 2, and confess from steam valve 9.Steam pressure can be by Pressure gauge 5 reflections and control; Excessive as pressure, then safety valve 7 is automatic steam discharge.

The waste gas that the utility model steam generator produces in heating process can directly pass through from heating tube 3, and from blast pipe 6 discharging atmosphere.The waste heat of waste gas is passed to water and steam between pot interior pipe by the tube wall of heating tube 3, and they further are heated.

The advantage of the utility model steam generator is: 1) it is together empty in the inside of pressure cooker Set up after one group of heating tube, waste gas residual heat is applied, simultaneously the bottom of a pan of arch Make the firepower of heating furnace comparatively concentrated, therefore make comparisons required fuel with the steam of equivalent The existing steam generator of consumption is few, and steam pressure can reach 0.4-0.6MPa, Temperature reaches 150 ℃; 2) waste gas is under the guiding of heating tube, blast pipe, directly from pressing Power pot top discharge, and be difficult for around heating furnace, dispersing, therefore of reduced contamination to environment.

Claims (2)

1, a kind of steam generator that includes heating furnace (1) and pressure cooker (2) is characterized in that:

1) inner space of pressure cooker has one group of heating tube (3) that can supply waste gas after burning to pass through, and the two ends of this pipe are fixed in respectively on the bottom surface and end face of pressure cooker;

2) have one on the end face of pressure cooker and can contain the blast pipe (6) that there is the heating tube top end opening in the residence.

2, as claim 1 fast steam generator, it is characterized in that: said pressure cooker (2) can have the arch bottom surface that can ride on heating furnace.
