Embodiment 1）

[0017] See Figure 1-3 , The continuous recovery and delivery device for high-temperature steam condensate in this embodiment includes: a main cylinder 1, a secondary cylinder 14, an intake switching valve 20 connected to a high-pressure gas source, and an exhaust switching valve 21 connected to the atmosphere. Both the main cylinder body 1 and the auxiliary cylinder body 14 are provided with water inlet one-way valves 17, 18 and water outlet one-way valves 13, 19. As an optimized solution, the main cylinder body 1 and the auxiliary cylinder body 14 are wrapped with an insulating layer.

[0018] The first outlet of the air intake switching valve 20 is connected to the secondary cylinder 14 through the high-pressure air pipe 16 , and the second outlet of the air intake switching valve 20 is connected to the main cylinder 1 .

[0019] The auxiliary cylinder body 14 is provided with a float type exhaust valve 15, which is closed when the liquid level in the auxiliary cylinder bo...

Embodiment 2

[0035] The working method of the continuous recovery conveying device of the high-temperature steam condensate in the above-mentioned embodiment 1, it comprises the following steps:

[0036] A. When the first lower valve of the intake switching valve 20 and the second upper valve of the exhaust switching valve 21 are closed, the first upper valve of the intake switching valve 20 and the exhaust switching valve 21 When the second lower valve is in the open state, the water inlet check valve 17 on the main cylinder 1 is opened by the high-temperature fluid and flows into the high-temperature fluid. Under the action of the gas, it is discharged through the water outlet check valve 19; the floating ball 10 in the floating ball valve opening and closing control mechanism in the main cylinder 1 gradually rises, driving the floating ball connecting rod 11 around its bottom end from bottom to top Gradually rotate and rise. When the floating ball connecting rod 11 is in line with the l...

Embodiment 3

[0039] As a modification of Embodiment 1, the control device includes: liquid level gauges arranged in the main cylinder and the auxiliary cylinder, and a controller connected to each liquid level gauge, and the inlet and exhaust switching valves are connected with the control The electric control valve connected with the device to realize the function of the control device.

[0040] As a further optional solution, the water inlet and water outlet one-way valves on the main cylinder and the auxiliary cylinder are electronically controlled one-way valves connected with the controller, and the high-pressure air source is canceled at this time.

Abstract

The invention provides a continuous recovery and conveying apparatus for condensate of high temperature steam. The apparatus comprises a main barrel, a secondary barrel, an intake changeover valve and an exhaust changeover valve, wherein the main barrel and the secondary barrel are both provided with an inflow water non-return valve and an outflow water non-return valve, a first outlet of the intake changeover valve is connected with the secondary barrel through a high pressure air tube, a second outlet of the intake changeover valve is connected with the main barrel, a ball float type exhaust valve is arranged in the secondary barrel, the ball float type exhaust valve is closed when a liquid level in the secondary barrel is higher than a set position and is opened when the liquid level in the secondary barrel is lower than the set position, a first inlet of the exhaust changeover valve is communicated with an air exhaust opening of the ball float type exhaust valve through a normal pressure air tube, a second inlet of the exhaust changeover valve is connected with the main barrel, and the interior of the main barrel is provided with a control device which is used for controlling operation of the intake changeover valve and the exhaust changeover valve according to the liquid level so as to control liquid feeding of the secondary barrel during liquid discharging of the main barrel and liquid discharging of the secondary barrel during liquid feeding of the main barrel, thereby cyclically forming continuous recovery and conveying of high temperature fluid.

Description

[0001] This application is a divisional application, the filing date of the original application: 2012-1-4, the application number: 201210000626.3, the name of the invention: continuous recovery and conveying device for high-temperature steam condensate. technical field [0002] The invention relates to the technical field of energy-saving equipment, specifically a continuous recovery and delivery device for high-temperature steam condensate, especially a continuous recovery and delivery device for high-temperature steam condensate with a specific gravity of 0.8-1.1 controlled by a floating ball driven by steam or compressed air . Background technique [0003] In the field of production, the steam and high-temperature fluid generated by heat exchange equipment are precious thermal energy resources. At present, the steam and high-temperature condensed water in many common equipment are recovered openly or not recovered at all. Energy is wasted and at the same time pollutes th...
