Right-angle type HTHP (High Temperature High Pressure) pulse-jet valve

Abstract

The invention discloses a right-angle type HTHP (High Temperature High Pressure) pulse-jet valve which comprises a valve body, an electromagnetic valve, a two-way cylinder, a valve stem, a valve sealing component, an air inlet end and an air outlet end, wherein the valve stem is coaxial to the air outlet end; the tail end of the valve stem is connected with the two-way cylinder, and the front end of the valve stem is connected with the valve sealing component; the valve sealing component comprises a seal valve clack and a seal valve base which are matched for use; the front end of the seal valve clack is provided with a guide piece which penetrates through the seal valve base. According to the right-angle type HTHP pulse-jet valve, the electromagnetic valve controls the two-way cylinder to perform bidirectional movement so as to drive the ascending and descending of the valve stem as well as separation and combination of the seal valve clack and the seal valve base, so that a jetting effect is realized; the guide piece is arranged, so that not only can the opening and closing direction be controlled, but also primary impact of HTHP gases can be avoided; in addition, a metal sealing part can be used for avoiding burning loss of a film, under the condition of ensuring the high-temperature sealing effect and the favorable jetting effect, the service life is improved manyfold, and the right-angle type HTHP pulse-jet valve has favorable popularization and use value.

Description

technical field [0001] The invention belongs to the technical field of blowing valves, in particular to a right-angle high-temperature and high-pressure pulse blowing valve. Background technique [0002] With the progress and development of coal chemical technology, how to solve the problem of dust removal is a systematic and key issue. Among them, the pulse dust collector is often used. Although there are different types, its injection principle is roughly the same. The blowing principle is: when the dust load on the surface of the filter bag increases and reaches a certain resistance, the pulse controller will issue instructions to trigger each control valve in sequence, open the pulse valve, control the opening frequency and instantaneous opening time, and control the high temperature and high pressure gas. (It can be nitrogen, steam, etc.) Instantaneous blowing force to purge dust. The problems in production practice are: the sealing technical problems of traditional so...

AI Technical Summary

Problems solved by technology

The problems in production practice are: traditional solenoid valves cannot solve the technical problems of sealing at high temperature (300°C-600°C), and the stability of the system operation cannot be solved.

However, to solve this problem, there is no corresponding blow valve structure yet.
