Water bath device capable of realizing thermal energy cyclic utilization and desorbing instrument including same

Abstract

The invention discloses a water bath device capable of realizing thermal energy cyclic utilization and a desorbing instrument including the same, and belongs to the field of unconventional natural gasmeasurement. The water bath device comprises a water bath heating tank, wherein the water bath heating tank comprises at least one water bath tank; heat-insulating covers are arranged on the water bath tanks; the heat-insulating covers are provided with holes for connecting desorbing tanks and air collecting graduated cylinders; middle parts of the heat-insulating covers are concave surfaces; theconcave surfaces are provided with small draining holes; the concave surfaces are used for importing moisture in the water bath tanks or water in the air collecting graduated cylinders into the waterbath tanks along the small draining holes. According to the small-sized water bath device for heating the desorbing tanks without any external water groove, a semi-enclosed heating manner is adopted,so that the heating temperature upper limit and heating efficiency are increased effectively; the heat-insulating covers are adopted for heating and preserving heat, so that the temperature distribution in the water bath tanks can be uniform, and an experiment result is optimized; through the heat-insulating covers, water drained from the air collecting graduated cylinders and water vapor evaporating in a heating process can be recycled, so that water resources are saved, and the environment is kept clean.

Description

technical field [0001] The invention relates to the field of unconventional natural gas measuring equipment, in particular to a water bath device for heating a desorption tank that can realize thermal energy recycling and a desorption instrument comprising the device. Background technique [0002] With the continuous improvement of social and economic development on energy and environmental protection requirements, unconventional natural gas has become a hot spot in the field of energy exploration. Unconventional natural gas includes shale gas, coalbed methane, tight sandstone gas and natural gas hydrate. As an important data to evaluate the potential of unconventional natural gas resources, gas content has always been valued by the industry. The desorption method is currently considered to be the most direct test method for measuring unconventional natural gas content. Wherein the water bath method is used the most, but the current existing products all use water tanks for...

Problems solved by technology

Among them, the water bath method is the most widely used, but the current existing products all use water tanks for water bath heating, which has obvious disadvantages

Such as: (1) The instrument is bulky and inconvenient to transport; (2) The water tank heating is open heating, and the upper limit of the heating temperature is low; (3) The open heating causes excessive heat loss, resulting in energy waste; (4) Open water tank heating It will cause uneven temperature distribution and poor experimental results; (5) the amount of water evaporation is large, wasting water resources; (6) the experiment for a small number of samples also needs to heat the water in the entire tank, the energy utilization rate is low, and the experimental results are poor

(7) When using a water tank to heat multiple desorption tanks, multiple samples can only be placed in the same water tank, and it is impossible to precisely control the temperature of a single sample
