The invention discloses a small heating oven of dry test samples, which is characterized in that a fan is arranged on the top of an oven body, and fan leaves are suspended above the test samples; the oven body and a door body take the material of stainless steels that are arranged integrally and in interlayers that are filled with heat insulator; a horizontal bracket is arranged above a heating pipe inside the oven body, the door body at the height of the horizontal bracket is opened with a sample feeding orifice, a test sample shelf can be inserted into the sample feeding orifice, takes the horizontal bracket as a guide rail, and can be kept on the horizontal bracket, the rear part of the test sample shelf is fixedly connected with an orifice blockage board that can block the sample feeding orifice, and the outer part of the orifice blockage board is fixedly connected with an operating handle. The small parching oven of the test samples has the advantages in all aspects such as energy-saving effect, even foam formation, safe use, convenient taking and placing of the test samples and shortened parching time, etc.

The invention provides a vertical air conditioner. The vertical air conditioner comprises an indoor unit. The indoor unit comprises a front panel, an air outflow frame, a rear backboard, a left side panel, a right side panel, a top cover plate and a mixed air display. A mixed air outlet is formed in the front panel. The top cover plate is provided with a non-heat-exchange air inlet, an induced draught fan and an air guiding device for opening or closing the non-heat-exchange air inlet. The induced draught fan is used for introducing indoor non-heat-exchange air into an inner air duct through the non-heat-exchange air inlet. According to the vertical air conditioner, non-heat-exchange air and heat exchange air can both be introduced to form mixed air, the mixed air is blown out of the mixed air outlet, and thereof the circulating air volume and the heat exchange speed of the indoor unit are increased. The non-heat-exchange air inlet is formed in the top cover plate, the induced draught fan is used for inducing air, the height of a heat exchanger can be increased without arranging a ventilation air duct, and therefore the capacity of the heat exchanger is improved. The mixed air display is independently arranged, production and mold cost can be reduced to the maximum extent, the arrangement position of the mixed air display is flexible, and the market competitiveness can be improved.

The invention discloses a method for purification and reuse of high-purity and high-yield methane stabilized gas from ethylene oxide produced by ethylene method, which includes the following steps: (1) natural gas enters a PSA system for dehydrocarbonation, decarburization and dehydration to obtain non-adsorbed phase gas The methane product gas enters the reactor reaction as a stable gas produced by ethylene oxide (EO) from ethylene; (2) Obtain the adsorption phase gas from (1), and return part of it to the ethylene oxide reaction cycle gas reaction; (3) The reaction cycle gas formed by the reaction is partially returned to the ethylene oxide reactor, and part of it enters the CO2 absorption tower for decarburization to form non-condensable gas and returns to the reactor; (4) The EO stripper top gas enters the EO reabsorption tower to form The non-condensable gas enters the full temperature range pressure swing adsorption (FTrPSA) to recover ethylene, and the part of the methane-rich tail gas flowing out is returned to (1); the part of the ethylene-rich gas flowing out is returned to the reaction cycle gas for recycling, and part of it is sent to ethylene rectification for recovery and refining Ethylene is recycled as the ethylene needed for EO reaction.

The invention discloses an air outlet mesh of an outdoor unit of an air conditioner, which comprises a frame body and a grate, wherein the grate is arranged in the frame body and comprises a plurality of annular strips; a plurality of radial strips are arranged between the adjacent annular strips; and the air guide surfaces of the radial strips and the axial direction of the frame body form an acute angle. The air outlet mesh of the outdoor unit of the air conditioner can increase the circulating air volume of an outdoor unit, reinforce the heat exchange effect of a heat exchanger, improve the air-conditioner performance and save energy sources.

The present invention provides a vertical air conditioner indoor unit, comprising: a housing with an air supply port, a first air inlet and a second air inlet; A tapered shape whose cross-section gradually decreases along the direction of the airflow; a deflector is arranged in the air duct and defines an annular air outlet gap with its tapered part, and the deflector is used to guide the airflow to the annular air outlet The gap allows the airflow to gradually converge toward the center of the airflow under the guidance of the inner wall of the air duct and flow out of the air outlet and the air supply port; and an air induction channel, formed between the housing and the air duct, has The inlet end communicated with the second air inlet, and the outlet end communicated with the air supply port, indoor air enters the housing through the second air inlet and is guided to the air supply port by the air induction channel . The vertical air conditioner indoor unit of the present invention has stronger wind force and longer air supply distance.

The invention discloses a method for heat transfer and heat dissipation with large heat and high heat flux density based on high-dimensional thermoelectricity. The temperature data acquisition / transmission module collects and transmits the real-time temperature data on the temperature detector in real time, and the control / temperature measurement module integrates the temperature detector. The time is modified in real time, the heat transfer channel in the control / temperature measurement module outputs accurate temperature signals for the collected temperature data, the external power measurement signal module analyzes and compares the output accurate temperature signals, and the high-dimensional heat dissipation matrix passes time synchronization constraints module to realize the large-area distribution control of 1~n groups of thermoelectric cooling chips; as a system-level precise temperature control technology, the present invention realizes a heat flux greater than 10^6W / cm2, a heat transfer distance of more than hundreds of meters, and a laboratory stage Precise control -196°C to 1200°C, the temperature difference between the head end and the end product is only 0.5°C, and the heat dissipation structure design can be customized.
