Abstract

The utility model relates to a steam-water mixer, which is characterized in that the mixer is composed of a water outlet tube, an outer shell, a heat exchange tube, a steam inlet and a water inlet tube; the heat exchange tube with skewed slot on the tube wall is arranged in the outer shell and is coaxial with the outer shell, two ends of the heat exchange tube are respectively connected with the small openings of the cone-shaped water outlet tube and the cone-shaped water inlet tube, the big openings of the cone-shaped water outlet tube and the cone-shaped water inlet tube are arranged outside of the upper and lower end of the outer shell, the stream inlet is connected with the outer shell side. The utility model has the advantages that the manufacture is easy, the cost is low; the noise is low during heating, the time of heating is short, and the efficiency is high.

Description

A kind of steam heater

Technical field

The utility model relates to a kind of steam heater, is used for the intensification of system's hot water, belongs to the steam heater technical field.

Background technology

Steam heater commonly used adopts the steel tube drilling method, promptly bores a lot of holes on steel pipe, and steam enters in the pipe from the hole on the tube wall, mixes with water in the pipe and heats, and the shortcoming of this device is:

1. manufacture difficulty is big, and the cost height;

2. noise is big when heating;

3. steam pressure must be greater than the heat hydraulic pressure.

Summary of the invention

The purpose of this utility model provides a kind of easily manufactured, and noise is little, and the high steam heater of efficient.

For realizing above purpose, the technical solution of the utility model provides a kind of steam heater, it is characterized in that, by the delivery port pipe, shell, heat exchanger tube, steam inlet and water inlet pipe are formed, tube wall is provided with the heat exchanger tube of skewed slot and is located in the shell, and is coaxial with shell, and its two ends are connected with the osculum of the water inlet pipe of the delivery port pipe of taper and taper respectively, be located at outside the shell upper and lower side for big mouthful of the delivery port pipe of taper and the water inlet pipe of taper, steam inlet is connected with shell side.

The angle of skewed slot is 35 °-60 ° on the tube wall of described heat exchanger tube

The utility model adopts steel shaft to the method for spraying into of cutting sth. askew, promptly on steel pipe, be provided with skewed slot, helping steam mixes with water and abates the noise, steam is entered in the pipe by the skewed slot on the steel pipe, with the water Hybrid Heating in the pipe, hot water is becoming big by pipe latus rectum behind the mixed zone simultaneously, makes the inside and outside build-up of pressure of pipe poor, make steam more can enter interior pipe, the efficiency of heating surface is higher.

The utility model has the advantages that:

1. be easy to make, and cost is low;

2. noise is little when heating;

3. the heating-up time is lacked the efficient height;

3. steam pressure can be less than the heat hydraulic pressure.

Description of drawings

Fig. 1 is a kind of steam heater structural representation;

Fig. 2 is the heat exchanger tube vertical view.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment

As shown in Figure 1, be a kind of steam heater structural representation, described a kind of steam heater is made up of delivery port pipe 1, shell 2, heat exchanger tube 3, steam inlet 4 and water inlet pipe 5.

The heat exchanger tube 3 that has skewed slot 6 on the tube wall is installed in the shell 2, coaxial with shell 2, its two ends are connected with the osculum of the water inlet pipe 5 of the delivery port pipe 1 of taper and taper respectively, be located at outside shell 2 upper and lower sides for big mouthful of the delivery port pipe 1 of taper and the water inlet pipe 5 of taper, steam inlet 4 is connected with shell 2 sides.

As shown in Figure 2, be the heat exchanger tube vertical view, evenly have three rounds on the tube wall of described heat exchanger tube 3, each has arranged 5 skewed slots 6, and the angle of skewed slot 6 is 45 °.

During work, the steam that with pressure is 0.3MPa-0.6MPa is entered in the shell 2 by steam inlet 4, enter in the heat exchanger tube 3 by the skewed slot on the heat exchanger tube 36, mix to realize instantaneous heating with the water that enters from water inlet pipe 5, the water after the heating is sent by delivery port pipe 1 under the effect of pump pressure and steam pressure.

Claims

1. steam heater, it is characterized in that, by delivery port pipe (1), shell (2), heat exchanger tube (3), steam inlet (4) and water inlet pipe (5) are formed, tube wall is provided with the heat exchanger tube (3) of skewed slot (6) and is located in the shell (2), coaxial with shell (2), its two ends are connected with the osculum of the water inlet pipe (5) of the delivery port pipe (1) of taper and taper respectively, be located at outside shell (2) upper and lower side for big mouthful of the delivery port pipe (1) of taper and the water inlet pipe (5) of taper, steam inlet (4) is connected with shell (2) side.

2. a kind of steam heater according to claim 1 is characterized in that, the angle of skewed slot (6) is 35 °-60 ° on the tube wall of described heat exchanger tube (3).
