Description

A kind of clean steam generator

Technical field

The utility model relates to steam generation field more particularly to a kind of clean steam generators.

Background technique

Many requirements of the place to steam quality are very high, directly processed in particular for the dry clean steam of cleaning Technique in and high-cleanness, high workshop, workshop the production environments control process such as humidification.In such as food, beverage, medical industry, collection At in the techniques such as electronics processing, there is comparable potential risk to product quality using industrial steam steam.Some factories are by allowing Industrial steam obtains clean steam by some high-precision stainless steel filters (filter core is as unit of micron).

Now more common clean steam generating system uses industrial steam for heating source, and heating pure water generates clean steam Vapour.The more typical one kind of such clean steam generator is actually volumetric heat exchanger, it has a very big storage tank, storage tank It is middle to store full pure water, there is steam pipe coil in water；Industrial steam is flowed through from coil pipe, heats pure water, clean steam is generated, by tank It sends out outlet at the top of body.Main control is the inflow for controlling storage tank.But the shortcomings that such design, is:

1. radiation loss is serious, and energy consumption is high due to storing a large amount of water；

2. since the coil pipe thermal efficiency is limited, while internal incrustation is difficult to clean up, therefore not using shortly generation steam production Foot, while pressure is unable to reach design requirement, industrial steam consumption is very big；

3. such huge steam generator material utilization amount is very big, if designed using all steel, equipment purchase expense It is all very big with mounting cost.

Utility model content

The main purpose of the utility model is to provide a kind of clean steam generator, which uses plate Formula heat exchanger can produce clean steam, small in size, light-weight.

To achieve the above objectives, the technical solution adopted in the utility model are as follows: a kind of clean steam generator, feature exist In, including be connected to source of purified water by first pipe plate heat exchanger, be connected to plate heat exchanger by second pipe Steam generating tank, the first pipe and second pipe the inlet and outlet phase with the cold pipe group of plate heat exchanger respectively Even, the upper end of steam generating tank is connected by third pipeline with gas utilization unit.

Preferably, along water (flow) direction the water pump being connected with controller is disposed in first pipe and to adjust First control valve of flow.

Preferably, the pressure sensor being connected with controller is provided in the steam generating tank.

Preferably, the liquidometer being connected with controller is provided on the steam generating tank.

Preferably, it is provided with the outlet conduit being in communication with the outside at the position of the close bottom of steam generating tank, gone out Valve is provided on waterpipe.

Preferably, steam-water separator is provided on third pipeline.

The utility model compared with prior art, has the advantages that

The clean steam generator generates steam using plate heat exchanger, and structure is simple, and occupied area is small.

Detailed description of the invention

Fig. 1 is the schematic diagram of a preferred embodiment according to the present utility model

Specific embodiment

It is described below for disclosing the utility model so that those skilled in the art can be realized the utility model.It retouches below Preferred embodiment in stating is only used as illustrating, it may occur to persons skilled in the art that other obvious modifications.

A kind of clean steam generator as shown in Figure 1 board-like is changed including what is be connected to by first pipe 3 with source of purified water The upper end venthole of hot device 12, the steam generating tank 5 being connected to by second pipe 4 with plate heat exchanger 12, steam generating tank 5 is logical Third pipeline 6 is crossed to be connected with gas utilization unit, and first pipe 3 and second pipe 4 respectively with the cold pipe group of plate heat exchanger Both ends connection.The heat exchange principle of the plate heat exchanger 12 uses the prior art.

Water pump 10 and the first control valve 9, the water pump are disposed with along the direction that fluid flows in first pipe 3 10 to provide power for fluid, and the water pump 10 and the first control valve 9 are connect with controller 11, and controller passes through described the One control valve 9 can adjust the flow of 3 upper fluid of first pipe.

The second pipe 4 is connected to steam generating tank 5 by the position of upper end, is added in pure water by plate heat exchanger 12 Steam generating tank 5 is entered by second pipe 4 in the form of steam water interface after heat, steam generating tank 5 can be by steam It is separated from water, clean steam is transported to gas utilization unit by third pipeline 6 by upper end venthole.The steam generating tank 5 Working principle use the prior art.

It is provided with the pressure sensor 13 and liquidometer 14 connecting with controller 11 in the steam generating tank 5, controls Device 11 can control the first control valve 9 by the pressure value that pressure sensor 13 detects to change the stream of fluid in pipeline Amount.It reach a certain height when the controller 11 reaches the liquid level in steam generating tank 5 by the detection of liquidometer 14, controller 11 Alarm signal is issued, while also can control the first control valve 9 and reducing flow, or even water pump 10 is stopped.In steam generating tank 5 Close lower end position at be provided with the outlet conduit 15 communicated with the outside world, ball valve 16 is provided on outlet conduit 15, when When liquid level in steam generating tank 5 is more than certain value, drained by opening ball valve 16.

Steam-water separator 7 is provided on the third pipeline 6 to further by the liquid in the steam in third pipeline 6 Body separation.

Basic principles, main features, and advantages of the present invention has been shown and described above.Current row The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments Only the principles of the present invention, the utility model also has respectively on the premise of not departing from the spirit and scope of the utility model Kind changes and improvements, these changes and improvements are both fallen in the range of claimed invention.The requires of the utility model Protection scope defined by appended claims and its equivalent.
