Energy-saving heat-accumulating type high temperature pure air testing system

Abstract

The invention discloses an energy-saving heat-accumulating type high temperature pure air testing system. A first heat accumulator, a fixed heat accumulator and a second heat accumulator are sequentially composed of ceramic honeycombs, refractory mortar castings, heat insulating layers, heat preservation layers and steel cylinders from inside to outside. A sliding rail consists of two concentric round steel rails. Supporting pieces are connected with the first heat accumulator and the sliding rail, and the second heat accumulator and the sliding rail, and are used for supporting the first heat accumulator and the second heat accumulator. At the initial heating stage, the right end of a cross is sequentially connected with the first heat accumulator, the fixed heat accumulator and the second heat accumulator. At the subsequent heating stage, the preheated second heat accumulator is moved to the right end of the cross through the sliding rail, the rear end of the second heat accumulator is connected with the front end of the fixed heat accumulator, and the first heat accumulator not preheated is moved to the rear end of the fixed heat accumulator to be preheated through the sliding rail. The energy-saving heat-accumulating type high temperature pure air testing system is suitable for testing equipment with high temperature and high pressure air required on the ground, high-flow high temperature and high pressure pure air is provided, and the energy-saving purpose is achieved through outlet gas exhaust waste heat.

Description

technical field [0001] The present invention relates to an energy-saving heat-storage type high-temperature pure air test system, in particular to an energy-saving heat-storage type high-temperature pure air test system, which is suitable for test equipment that requires high-temperature, high-pressure pure air on the ground, and can provide high-temperature, high-pressure pure air with a large flow rate . Background technique [0002] There are many ways to heat air, and the commonly used methods are arc heating, combustion heating, regenerative heating and shock wave heating. And if you need both high temperature and high pressure air, and when you need pure air, the requirements for heating methods are more stringent. Although the arc heating method can make the temperature reach 3000K or even higher, the non-uniformity of the airflow and the pollution of the heating airflow make this heating method unable to provide pure air; the combustion heating is to inject oxygen i...

Therefore, when the heat accumulator is used to heat the high-pressure air, the required high-pressure air heating temperature will not be enough

[0006] To sum up, there are few heating methods for pure air, and the heat accumulator is one of the options, so it can be used to provide high-temperature and high-pressure pure air; when the conventional heat accumulator heats the high-pressure air, the tail heating temperature is not enough, and the outlet Gas waste heat waste and other issues, so there is an urgent need to provide a new energy-saving air heating system
