Problems solved by technology

[0019] Exhaust muffler in use at present, for example Chinese patent publication number: 85202382.0 discloses a kind of " KX-P type exhaust muffler ", and for example Chinese patent publication number: 85202382.0 discloses a kind of " KX-A type safety valve muffler " , KX-P and KX-A muffler series are suitable for boiler steam exhaust and other gas exhaust mufflers in petroleum, chemical, metallurgy, textile and other industrial sectors. Empty muffler, although they have obvious noise reduction effect, muffler structure and in the basic structure of preferred embodiment, they have the following problems and shortcoming about formation and are: throttling and decompression series generally only get 2 levels (that is: take over It is composed of 2-stage throttling and decompression tubes of the outer cylinder), the noise reduction of the designed muffler is generally about 35dB(A), in order to achieve the injection area of ​​the small hole injection, therefore, the total length of their body cylinder Relatively slender (i.e.: 1. The sound attenuation is generally relatively low; 2. The installation space they occupy is also large; 3. When the reaction force is applied, the safety of mutual balance is also poor) and so on.

Abstract

A compound muffler for high temperature and high pressure steam / gas discharge. It is a new type of noise reduction device for various types of high-temperature and high-pressure air exhaust / exhaust steam, including: the two ends of the injection outer cylinder armor are welded with oval head armor; One end of the head armor piece is welded with the interface throttle pipe piece A with the pipe end plate A piece, and the other end of the oval head piece A piece is welded with the lifting ear piece A; On the joint throttling tube A, there is welded the plugging ring plate A with the throttling and decompression tube A and the tube end plate B respectively; the above-mentioned related components are welded firmly and manufactured with them. Consists of a complete set of products.

Description

Technical field [0001] The invention relates to a high-temperature and high-pressure steam / gas discharge composite muffler, which is a new type of noise reduction device for exhausting / exhausting steam at various high temperatures and high pressures. [0002] The high-speed air flow is ejected from the container, impacting and shearing the surrounding still air, causing severe gas disturbance near the nozzle, resulting in high-level aerodynamic noise, forming exhaust jet noise. For example, jet planes, rocket launches, etc. produce jet noise of 140-160dB(A), as well as boiler exhaust in thermal power plants, blast furnaces in the metallurgical industry, various gas emissions in chemical plants, and exhaust venting from air compressors, etc. There will be a strong exhaust jet noise. The noise is continuous broadband noise with peak frequencies proportional to airflow velocity and inversely proportional to exhaust pipe diameter. When the airflow velocity of the exhaust port re...
