Problems solved by technology

[0005] 2. The sampling efficiency of pure steam condensation is relatively slow, and the sampling speed is 10ml / min
[0006] 3. The temperature of the cooling water in the water tank is relatively high after heat exchange through the shell side of the steam sampler, and the water tank has no self-cooling function. It can only be drained after one point of use is used, and new cooling water can be added. point-of-use sampling

Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] figure 2 A steam sampler is shown, comprising a steam sampler 1, a water tank 2 and a pump 3, the steam sampler includes a sampler shell 11 and a sampler tube 12, and one end of the sampler tube 12 is The other end of the steam inlet 121 is a steam condensate outlet 122, the sampler shell side 11 is connected to the water tank 2 through a circulation pipeline, and the sampler shell side 11 is provided with a sampler cooling water inlet 111 and a sampler cooling water The outlet 112 circulates the water in the water tank 2 into the sampler shell side 11 through the pump 3 arranged in the circulation pipeline.

[0030] The cooling water outlet 112 of the sampler is provided with a cooling water cooling box 4 between the water tanks 2, and the cooling water cooling box 4 is provided with a cooling water inlet 41 of the cooling box and a cooling wa...

Abstract

The invention discloses a steam sampling machine which comprises a steam sampling device, a water tank and a pump, wherein a cooling water cooling box is arranged between a sampling device cooling water outlet and the water tank; the steam sampling machine further comprises a refrigeration unit; the refrigeration unit comprises a compressor, a condenser, an expansion valve and an evaporator, which are sequentially connected; the evaporator is arranged in the cooling water cooling box; heat of cooling water in the cooling box is absorbed through the evaporator to realize the purpose of cooling water cooling. According to the invention, the cooling heat exchange device and the refrigerating unit are ingeniously combined in the steam sampling machine, so that the working efficiency of the steam sampling machine is improved greatly; since circulating cooling water which is in a high temperature state and flows out from the sampling device is rapidly cooled to be reused in a low temperature state, the steam condensation sampling speed is increased greatly.

Description

technical field [0001] The invention relates to a sampling device, in particular to a steam all-purpose device, that is, a device for condensing and sampling steam at points of use in a steam distribution system. Background technique [0002] In the prior art, the pure steam condensation sampling technology for the use point in the pure steam distribution system is to pass the pure steam at the use point into the tube side of the sampler, and pump the water in the water tank into the sampler through the circulation pump. Shell side, use the water in the water tank as cooling water to condense the pure steam in the tube side, such as figure 1 shown. [0003] The problems with this technique are as follows: [0004] 1. The cooling water temperature in the water tank is 25°C or higher. [0005] 2. The sampling efficiency of pure steam condensation is relatively slow, and the sampling speed is 10ml / min. [0006] 3. The temperature of the cooling water in the water tank is re...
